--captions by vitac--

00:00:04,655 --> 00:00:07,655
Captions paid for by
Discovery communications
3
00:00:51,068 --> 00:00:54,344
Narrator: ever since the days
Of the american wild west,
4
00:00:54,344 --> 00:00:57,655
Badges have been a way to tell
The good guys from the bad.
5
00:00:57,655 --> 00:01:01,551
Sheriffs don't raise posses to
Maintain law and order anymore,
6
00:01:01,551 --> 00:01:04,724
But a badge continues to be
A powerful symbol,
7
00:01:04,724 --> 00:01:08,827
And simply flashing one
Can still stop a suspect cold.
8
00:01:15,000 --> 00:01:17,344
The badge
Comes with the uniform.
9
00:01:17,344 --> 00:01:20,241
It identifies
The officer's rank and unit.
10
00:01:20,241 --> 00:01:22,862
So it's an accessory
That makes a statement.
11
00:01:24,931 --> 00:01:26,758
Each one is custom-made.
12
00:01:26,758 --> 00:01:31,586
The client spells out the
Specifications on an order form,
13
00:01:31,586 --> 00:01:35,689
Right down to the metal finish
And the color of the lettering.
14
00:01:42,068 --> 00:01:44,827
This machine delivers
A powerful punch
15
00:01:44,827 --> 00:01:49,000
To cut sheriff star shapes
From a coiled sheet of brass.
16
00:01:53,862 --> 00:01:57,275
They place a star shape
In the steel mold of a press.
17
00:01:57,275 --> 00:02:01,586
It applies about 170,000 pounds
Per square centimeter
18
00:02:01,586 --> 00:02:03,724
To make an impression
On the badge.
19
00:02:09,586 --> 00:02:13,551
A punch press trims the ragged
Edges to make it look neater.
20
00:02:19,206 --> 00:02:22,034
A mechanical stamper
Then inscribes the company name
21
00:02:22,034 --> 00:02:23,482
On the back of the badge.
22
00:02:26,551 --> 00:02:28,241
This computerized engraver
23
00:02:28,241 --> 00:02:31,344
Then marks the rank and other
Information on the front.
24
00:02:35,344 --> 00:02:37,931
They apply a couple of dabs
Of silver solder
25
00:02:37,931 --> 00:02:40,517
To the back of the badge.
26
00:02:40,517 --> 00:02:42,103
It's the substance
27
00:02:42,103 --> 00:02:45,034
That will hold the catch
And pin joint in place.
28
00:02:45,827 --> 00:02:49,103
They blast the back of the badge
With a torch,
29
00:02:49,103 --> 00:02:52,586
And it reaches a temperature of
Over 1,400 degrees fahrenheit.
30
00:02:52,586 --> 00:02:56,896
This causes the solder to melt,
Fusing the parts to the badge.
31
00:03:02,103 --> 00:03:06,413
They then position the badge
Under a hydraulic press.
32
00:03:06,413 --> 00:03:08,689
Like a steel fist,
33
00:03:08,689 --> 00:03:12,517
It punches the badge to give it
The correct curvature.
34
00:03:18,517 --> 00:03:21,724
Here they spray a mix of water
And tiny glass beads
35
00:03:21,724 --> 00:03:23,448
Onto the back.
36
00:03:23,448 --> 00:03:25,172
This is called wet blasting,
37
00:03:25,172 --> 00:03:28,482
And it makes the finish cleaner
And more textured.
38
00:03:34,448 --> 00:03:36,965
A technician now hooks the pin
In the joint
39
00:03:36,965 --> 00:03:38,793
That was soldered
Onto the badge.
40
00:03:38,793 --> 00:03:41,206
He slides the assembly
Onto a rivet
41
00:03:41,206 --> 00:03:43,931
Automatically served up
By this machine.
42
00:03:43,931 --> 00:03:45,724
The machine applies pressure
43
00:03:45,724 --> 00:03:50,310
To expand the rivet
And lock everything in place.
44
00:03:50,310 --> 00:03:52,551
The pin now fits in the catch,
45
00:03:52,551 --> 00:03:54,586
Which will enable the badge
46
00:03:54,586 --> 00:03:57,413
To be fastened onto
The police officer's uniform.
47
00:03:59,172 --> 00:04:02,862
Next, they brush enamel
Into the engraved lettering.
48
00:04:02,862 --> 00:04:05,482
The enamel is a mix
Of glass and water,
49
00:04:05,482 --> 00:04:08,103
Which comes from an ancient
Metalworking technique
50
00:04:08,103 --> 00:04:09,482
Called cloisonné.
51
00:04:15,551 --> 00:04:17,379
They fire the badge in a kiln,
52
00:04:17,379 --> 00:04:20,241
And the glass enamel
Melts into the lettering.
53
00:04:21,413 --> 00:04:22,620
After it hardens,
54
00:04:22,620 --> 00:04:25,551
They grind the enameled sections
Against a stone
55
00:04:25,551 --> 00:04:27,724
To expose the inscriptions.
56
00:04:32,379 --> 00:04:35,241
They then polish the badge
To a mirror finish.
57
00:04:40,758 --> 00:04:42,275
This automated rack
58
00:04:42,275 --> 00:04:45,620
Immerses the badges
In a electroplating solution
59
00:04:45,620 --> 00:04:48,931
To give the brass
A protective layer of nickel.
60
00:04:48,931 --> 00:04:52,000
They plate some badges
With 24-karat gold.
61
00:04:56,137 --> 00:05:00,517
Now they apply a strong adhesive
To the back of a medallion...
62
00:05:00,517 --> 00:05:02,620
Then attach it to the center
Of the badge.
63
00:05:02,620 --> 00:05:04,448
The medallion
Has an official emblem.
64
00:05:04,448 --> 00:05:08,137
It's specific to
The police force's jurisdiction.
65
00:05:11,689 --> 00:05:14,206
They adjust the catch
And its hardware
66
00:05:14,206 --> 00:05:17,862
To ensure it moves freely
And is in good working order.
67
00:05:17,862 --> 00:05:22,586
After all, no officer
Wants to lose his or her badge.
68
00:05:26,206 --> 00:05:30,379
They give it a shine and check
For surface imperfections.
69
00:05:30,379 --> 00:05:33,758
And now it's ready
To report for duty.
70
00:05:33,758 --> 00:05:37,827
It takes three weeks to make
One of these police badges,
71
00:05:37,827 --> 00:05:40,965
And they should be good
For a lifetime of service.
72
00:05:52,931 --> 00:05:54,275
Narrator:
The word "Muffin"
73
00:05:54,275 --> 00:05:55,758
Appeared in britain
Around the 11th century.
74
00:05:55,758 --> 00:05:57,172
In victorian times,
75
00:05:57,172 --> 00:06:00,103
Muffins were bought in
The street from the muffin man,
76
00:06:00,103 --> 00:06:03,000
Made famous in the popular
Children's nursery rhyme.
77
00:06:03,000 --> 00:06:05,862
In america,
Cooks began to experiment
78
00:06:05,862 --> 00:06:10,137
With english muffin recipes,
And the modern muffin was born.
79
00:06:15,172 --> 00:06:17,689
These muffins
Are a lot like homemade,
80
00:06:17,689 --> 00:06:19,310
Except to make this many,
81
00:06:19,310 --> 00:06:21,655
You need
Some pretty big equipment
82
00:06:21,655 --> 00:06:23,310
And a heap of ingredients.
83
00:06:28,103 --> 00:06:29,896
At this commercial bakery,
84
00:06:29,896 --> 00:06:32,620
They make them with flour,
85
00:06:32,620 --> 00:06:35,551
Then add salt, baking powder,
86
00:06:35,551 --> 00:06:38,862
And a prepared mixture
Of dry ingredients.
87
00:06:41,344 --> 00:06:44,724
Finally, they add vanilla flavor
And start up the barrel mixer.
88
00:06:44,724 --> 00:06:46,206
It's a big one --
89
00:06:46,206 --> 00:06:49,551
Large enough to hold
A ton of batter at least.
90
00:06:49,551 --> 00:06:53,896
Next, they add oil and water,
Then vegetable shortening.
91
00:07:01,793 --> 00:07:04,758
Now here come the blueberries.
92
00:07:04,758 --> 00:07:06,724
They go into the mix
Once they're thawed.
93
00:07:06,724 --> 00:07:08,275
Berries are delicate,
94
00:07:08,275 --> 00:07:11,344
So workers take care
To pour them out slowly,
95
00:07:11,344 --> 00:07:14,310
Weighing each bucket
To add just the right amount.
96
00:07:18,758 --> 00:07:22,344
Down below, workers pour out
Close to a ton of batter
97
00:07:22,344 --> 00:07:23,206
From the mixer.
98
00:07:23,206 --> 00:07:24,724
That's a whole lot of batter.
99
00:07:24,724 --> 00:07:28,448
Just one batch
Makes about 7,000 muffins.
100
00:07:31,241 --> 00:07:33,689
They cover the trough
To protect the batter
101
00:07:33,689 --> 00:07:37,241
Until it goes on
To fill baking pans like these
102
00:07:37,241 --> 00:07:41,275
That can hold 54 muffins,
Each with its own paper liner.
103
00:07:41,275 --> 00:07:43,103
A conveyor advances the pans
104
00:07:43,103 --> 00:07:46,034
Towards a machine
Called a batter depositor.
105
00:07:47,137 --> 00:07:49,586
Prepared batter
Pumps in from the trough
106
00:07:49,586 --> 00:07:52,241
And into the pans
As they pass below it.
107
00:07:53,517 --> 00:07:56,931
The depositor fills the pans
One row at a time,
108
00:07:56,931 --> 00:08:00,241
Measuring out the batter
By weight.
109
00:08:06,103 --> 00:08:07,931
At the next station,
110
00:08:07,931 --> 00:08:09,758
Blueberries
Pass through a funnel
111
00:08:09,758 --> 00:08:11,206
Equipped with a turning gear
112
00:08:11,206 --> 00:08:14,379
And drop
Right onto the muffin tops.
113
00:08:21,379 --> 00:08:25,689
A bar placed across the conveyor
Blows filtered air
114
00:08:25,689 --> 00:08:28,551
To remove any stray berries
From the pans
115
00:08:28,551 --> 00:08:30,896
As they advance to the gas oven.
116
00:08:37,344 --> 00:08:41,965
A metal arm pushes them right in
To bake for about 30 minutes.
117
00:08:41,965 --> 00:08:46,413
The oven, open on both sides,
Has dampers to keep in the heat.
118
00:08:50,482 --> 00:08:54,000
The muffins come out of the oven
Baked a golden brown.
119
00:08:55,551 --> 00:08:58,517
The pans cool for a few minutes
And then continue on
120
00:08:58,517 --> 00:09:02,310
To a custom-designed machine
That's pretty handy.
121
00:09:02,310 --> 00:09:04,448
It removes the muffins
From the pan
122
00:09:04,448 --> 00:09:06,655
And packages them
All automatically.
123
00:09:06,655 --> 00:09:11,206
Suction cups seize
Cardboard flats two at a time
124
00:09:11,206 --> 00:09:13,827
And push them
Onto a tray former.
125
00:09:15,448 --> 00:09:18,137
The forming head pushes down
On the preglued cardboard
126
00:09:18,137 --> 00:09:21,310
And voilĂ --
Out comes a perfectly square box
127
00:09:21,310 --> 00:09:23,620
That falls
Right onto the conveyor belt.
128
00:09:23,620 --> 00:09:25,551
Pans full of baked muffins
129
00:09:25,551 --> 00:09:28,413
Follow alongside
On another conveyor.
130
00:09:31,206 --> 00:09:32,482
At the next stop,
131
00:09:32,482 --> 00:09:35,000
Suction cups lift the muffins
Out of their pans.
132
00:09:35,000 --> 00:09:36,655
With military precision,
133
00:09:36,655 --> 00:09:39,000
They set them down
Into neat rows
134
00:09:39,000 --> 00:09:42,517
In the cardboard boxes
That wait on the back conveyor.
135
00:09:42,517 --> 00:09:44,241
The conveyor
Carries the filled boxes
136
00:09:44,241 --> 00:09:45,931
To a station
Where they're covered,
137
00:09:45,931 --> 00:09:49,517
Top and bottom,
With a sheet of clear plastic.
138
00:09:49,517 --> 00:09:53,931
Heated blades cut and seal
The plastic at both ends.
139
00:09:55,586 --> 00:09:58,413
Then the boxes
Pass through a heat tunnel
140
00:09:58,413 --> 00:10:01,034
That shrinks the plastic
Snugly over the trays.
141
00:10:01,034 --> 00:10:02,931
They're now ready for shipping
142
00:10:02,931 --> 00:10:05,620
To customers
In the food-service industry.
143
00:10:05,620 --> 00:10:08,586
On another line,
Preprinted plastic film
144
00:10:08,586 --> 00:10:12,793
Wraps the individual muffins
As they flow along the conveyor.
145
00:10:14,620 --> 00:10:17,448
Rotating brushes
Keep them moving forward
146
00:10:17,448 --> 00:10:21,068
While blades come down
To separate the continuous roll
147
00:10:21,068 --> 00:10:24,310
Into individually wrapped
Muffins ready for retail sale.
148
00:10:29,551 --> 00:10:32,965
Blueberry, bran,
Pecan strudel, lemon poppy.
149
00:10:32,965 --> 00:10:38,172
With so many flavors to choose
From, why not try some of each?
150
00:10:54,000 --> 00:10:56,275
Narrator: the best car washes
Tackle everything
151
00:10:56,275 --> 00:10:59,103
From road grime and dead bugs
To bird droppings
152
00:10:59,103 --> 00:11:01,241
That eat away at the paint
And metal of your vehicle.
153
00:11:01,241 --> 00:11:03,655
Car washes help you
Preserve your investment
154
00:11:03,655 --> 00:11:05,896
And increase its resale value.
155
00:11:05,896 --> 00:11:07,379
They save you time
156
00:11:07,379 --> 00:11:10,931
And help you feel proud about
The vehicle you're driving.
157
00:11:15,103 --> 00:11:19,034
A state-of-the-art car wash can
Be an eye-opening experience.
158
00:11:21,103 --> 00:11:23,586
Assorted soaps and waxes
Clean and pamper
159
00:11:23,586 --> 00:11:26,620
Every part of the vehicle
Like never before.
160
00:11:28,275 --> 00:11:31,000
This effective, yet gentle,
Cleaning power
161
00:11:31,000 --> 00:11:34,551
Is made possible using the
Latest car-cleaning technology.
162
00:11:39,517 --> 00:11:42,689
It starts with welding together
The steel frame
163
00:11:42,689 --> 00:11:45,655
That travels inside the bay
Of the car wash,
164
00:11:45,655 --> 00:11:48,758
Then adding the steel
And fiberglass walls.
165
00:11:53,965 --> 00:11:55,724
Using a milling machine,
166
00:11:55,724 --> 00:11:59,103
The worker then makes the wheels
On which the frame travels.
167
00:11:59,103 --> 00:12:02,689
The machine first prepares the
Center hole where the axle goes,
168
00:12:02,689 --> 00:12:05,586
Then makes a groove in the wheel
So it can ride on a track.
169
00:12:08,689 --> 00:12:13,034
Before long, a steel blank
Becomes a finished drive wheel.
170
00:12:15,724 --> 00:12:19,310
He then welds the wheel
Onto a drive shaft.
171
00:12:25,379 --> 00:12:28,724
He places the wheel assembly
In the bottom of the steel frame
172
00:12:28,724 --> 00:12:30,931
And bolts it in place.
173
00:12:37,793 --> 00:12:40,034
He then connects
A hydraulic motor
174
00:12:40,034 --> 00:12:42,103
To the end of the wheel assembly
175
00:12:42,103 --> 00:12:44,896
And makes sure
It couples together perfectly.
176
00:12:49,103 --> 00:12:51,620
Here a worker puts together
The brush assembly
177
00:12:51,620 --> 00:12:54,103
That cleans the sides
Of the vehicle.
178
00:12:55,586 --> 00:12:59,034
The brushes are made of material
Called poly-flex.
179
00:12:59,034 --> 00:13:01,758
It comes cut to various lengths
180
00:13:01,758 --> 00:13:04,758
So that it gets
Into those hard-to-clean places.
181
00:13:08,896 --> 00:13:11,689
Poly-flex won't trap in
Dirt particles.
182
00:13:11,689 --> 00:13:14,689
It's smooth and very gentle
On the vehicle.
183
00:13:18,068 --> 00:13:20,241
The finished side-brush assembly
184
00:13:20,241 --> 00:13:23,655
Consists of seven alternating
Columns of poly-flex.
185
00:13:25,586 --> 00:13:28,827
A worker puts together the
Pneumatic regulators and gauges
186
00:13:28,827 --> 00:13:31,413
That control many aspects
Of the car wash,
187
00:13:31,413 --> 00:13:33,068
Including the brush assemblies
188
00:13:33,068 --> 00:13:36,241
And the distribution
Of soaps and waxes.
189
00:13:39,620 --> 00:13:42,586
He then bolts the hydraulic pump
To the frame.
190
00:13:46,655 --> 00:13:51,310
He screws on the system's
Hydraulic filter...
191
00:13:51,310 --> 00:13:54,103
Then connects
The hydraulic pressure line
192
00:13:54,103 --> 00:13:56,034
And makes certain it's secure.
193
00:13:58,793 --> 00:14:01,344
The hydraulic power system
194
00:14:01,344 --> 00:14:04,206
Moves the car-wash frame
And rotates the brushes,
195
00:14:04,206 --> 00:14:07,103
But a computer
Controls everything.
196
00:14:09,413 --> 00:14:12,379
He hooks up the system wires
That connect to the computer.
197
00:14:12,379 --> 00:14:14,172
The computer makes it possible
198
00:14:14,172 --> 00:14:16,827
For the car wash to run
Without an operator.
199
00:14:22,551 --> 00:14:24,586
Workers then install the rack
200
00:14:24,586 --> 00:14:26,931
That supports
An overhead curtain.
201
00:14:28,724 --> 00:14:31,586
A worker attaches a shaft
To the rack...
202
00:14:31,586 --> 00:14:34,206
Then a heavy-duty bearing.
203
00:14:36,551 --> 00:14:38,965
When the bearing assembly
Is in place,
204
00:14:38,965 --> 00:14:41,482
He secures the rack
To the frame.
205
00:14:43,551 --> 00:14:45,793
He tests the rack
To make sure
206
00:14:45,793 --> 00:14:47,965
Its computer-controlled
Pneumatic cylinders
207
00:14:47,965 --> 00:14:50,620
Manipulate the overhead curtain
Correctly.
208
00:14:55,137 --> 00:14:58,586
He tests the oscillating
High-pressure nozzles.
209
00:15:01,655 --> 00:15:05,517
Then he makes sure the wheels
Move the frame properly.
210
00:15:07,344 --> 00:15:09,655
He turns on
All the brush assemblies
211
00:15:09,655 --> 00:15:11,137
That clean and polish the car
212
00:15:11,137 --> 00:15:14,034
And makes sure they spin and
Oscillate in perfect harmony.
213
00:15:17,965 --> 00:15:21,344
The definitive test, of course,
Is an actual car wash
214
00:15:21,344 --> 00:15:24,000
That proves the system
Works flawlessly
215
00:15:24,000 --> 00:15:25,724
And that every part
Of the vehicle
216
00:15:25,724 --> 00:15:29,344
Gets the best washing
And waxing possible.
217
00:15:35,413 --> 00:15:37,137
After a quick drying,
218
00:15:37,137 --> 00:15:40,517
This vehicle drives out
Of the car wash sparkling clean.
219
00:15:54,482 --> 00:15:56,758
Narrator: life without pressure
Gauges would be pretty rough.
220
00:15:56,758 --> 00:15:58,034
Figuring out everyday things
221
00:15:58,034 --> 00:15:59,896
Like oil pressure, air pressure,
And blood pressure
222
00:15:59,896 --> 00:16:02,068
Would be almost impossible.
223
00:16:02,068 --> 00:16:03,689
Without pressure gauges,
224
00:16:03,689 --> 00:16:06,137
We'd even have trouble
Taking a proper shower
225
00:16:06,137 --> 00:16:09,000
Because getting the correct
Water pressure in our homes
226
00:16:09,000 --> 00:16:11,517
Would be a hit-and-miss affair.
227
00:16:14,620 --> 00:16:17,241
For a pressure gauge
To be trustworthy,
228
00:16:17,241 --> 00:16:19,931
Whether it's measuring gases
Or liquids,
229
00:16:19,931 --> 00:16:23,620
It must be exceptionally
Well-made and accurate.
230
00:16:23,620 --> 00:16:26,724
To start, a worker loads
An aluminum faceplate
231
00:16:26,724 --> 00:16:28,172
Into a printing press.
232
00:16:28,172 --> 00:16:29,551
It applies a colored scale
233
00:16:29,551 --> 00:16:33,310
Used for measuring pressure
In pounds per square inch.
234
00:16:34,586 --> 00:16:36,724
The type of scale it prints
235
00:16:36,724 --> 00:16:38,965
Depends on the measuring unit
Being used.
236
00:16:44,241 --> 00:16:45,896
Then a worker puts a copper tube
237
00:16:45,896 --> 00:16:47,551
Into a bending machine
238
00:16:47,551 --> 00:16:51,241
That bends, cuts, and flattens
Sections of the tube.
239
00:16:54,896 --> 00:16:57,275
The amount of flattening
And bending
240
00:16:57,275 --> 00:17:00,448
Determines the pressure range
The gauge can measure.
241
00:17:00,448 --> 00:17:03,931
Each piece becomes
A pressure-sensing tube
242
00:17:03,931 --> 00:17:05,965
Known as a bourdon tube.
243
00:17:08,551 --> 00:17:10,931
Then a worker
Cuts lengths of brass
244
00:17:10,931 --> 00:17:13,241
That he machines
Into connectors.
245
00:17:13,241 --> 00:17:16,172
They will link the bourdon tube
To an inlet pipe.
246
00:17:23,275 --> 00:17:26,482
He melts zinc solder
In the connector's receptacle,
247
00:17:26,482 --> 00:17:29,689
And he mounts the bourdon tube
In the correct position.
248
00:17:30,758 --> 00:17:33,344
He fills the gap
Between the connector
249
00:17:33,344 --> 00:17:35,655
And the bourdon tube
With solder.
250
00:17:35,655 --> 00:17:39,551
Then he flushes the heated piece
With water to cool it down,
251
00:17:39,551 --> 00:17:42,206
Sealing the tube in place.
252
00:17:46,068 --> 00:17:48,965
He puts the cooled piece
On a mounting fixture
253
00:17:48,965 --> 00:17:51,448
And solders the other end
Of the bourdon tube
254
00:17:51,448 --> 00:17:53,655
To the gauge's
Internal mechanism.
255
00:17:56,551 --> 00:17:59,379
He seals the gap
And cools it down.
256
00:18:01,655 --> 00:18:04,206
Then he puts
The finished pieces,
257
00:18:04,206 --> 00:18:07,034
Or pressure-system assemblies,
As they're now called,
258
00:18:07,034 --> 00:18:09,172
Into a cleaning machine.
259
00:18:09,172 --> 00:18:11,551
Its hot, soapy water
Washes away any dirt
260
00:18:11,551 --> 00:18:14,000
And loose solder particles.
261
00:18:17,137 --> 00:18:18,689
The pressure-system assemblies
262
00:18:18,689 --> 00:18:20,689
Then go on
To a leak-testing machine
263
00:18:20,689 --> 00:18:23,000
That pushes air into the tubes.
264
00:18:27,103 --> 00:18:31,034
A stable pressure reading
Indicates there is no leakage.
265
00:18:36,896 --> 00:18:39,482
Another worker
Takes a gear mechanism,
266
00:18:39,482 --> 00:18:42,689
Which controls the mechanical
Movement inside the gauge,
267
00:18:42,689 --> 00:18:44,724
And places it on the connector.
268
00:18:44,724 --> 00:18:48,206
A machine screws
The gear mechanism in place.
269
00:18:51,482 --> 00:18:54,379
He then takes
The gear's connecting link
270
00:18:54,379 --> 00:18:56,827
And rivets it
To the pressure-system assembly.
271
00:19:03,517 --> 00:19:05,586
He fits
The pressure-system assembly
272
00:19:05,586 --> 00:19:08,517
Inside a protective
Stainless-steel housing.
273
00:19:08,517 --> 00:19:10,758
A machine
Screws it all together.
274
00:19:17,448 --> 00:19:20,655
Next, a worker
Calibrates the assembly.
275
00:19:20,655 --> 00:19:23,793
She loosens up
The connecting link slightly
276
00:19:23,793 --> 00:19:25,344
To prevent friction,
277
00:19:25,344 --> 00:19:29,586
Puts on the indicator needle,
And runs a test.
278
00:19:29,586 --> 00:19:32,103
After a bit more adjusting,
279
00:19:32,103 --> 00:19:35,379
She puts the faceplate and
The indicator needle back on.
280
00:19:36,551 --> 00:19:39,137
She ensures the gauge
Reads accurately
281
00:19:39,137 --> 00:19:40,655
At three key positions
282
00:19:40,655 --> 00:19:44,000
And then screws the faceplate
Onto the gauge.
283
00:19:46,551 --> 00:19:50,482
A final test confirms
It is calibrated properly.
284
00:19:52,068 --> 00:19:55,172
Then she puts a glass cover
Over the faceplate
285
00:19:55,172 --> 00:19:58,206
And adds a steel ring
To hold it in place.
286
00:19:58,206 --> 00:20:01,413
A crimping machine
Evenly folds the ring's edge
287
00:20:01,413 --> 00:20:04,758
Until it makes a perfect seal.
288
00:20:08,172 --> 00:20:11,103
Now she fills the gauge
With glycerin.
289
00:20:11,103 --> 00:20:15,034
Glycerin lubricates
The internal mechanical parts
290
00:20:15,034 --> 00:20:17,793
And increases the lifetime
Of the gauge.
291
00:20:17,793 --> 00:20:20,931
Glycerin also absorbs
Vibration well,
292
00:20:20,931 --> 00:20:25,344
Which helps the indicator needle
Remain stable during operation.
293
00:20:26,689 --> 00:20:28,965
A worker completes
The pressure gauge
294
00:20:28,965 --> 00:20:31,758
By sealing off the fill hole
With a rubber plug.
295
00:20:34,206 --> 00:20:38,413
But, of course, not all gauges
Are built the same way.
296
00:20:38,413 --> 00:20:41,793
As accurate and dependable
As a swiss watch,
297
00:20:41,793 --> 00:20:46,172
A trustworthy pressure gauge
Also has a pretty face.
298
