The metal strip is treated with etching acids that "melt away" the uncoated portion of metal, leaving an impression of the design. Computerized engraving is done by keying the designs or letters into the computer; the designs are transmitted to an "arm" on the computer which "draws" (engraves) them onto the metal plate. This is a shop or plant only classification. Repair work when specified is limited to work performed at the shop or plant.

This classification excludes all outside repair work which is to be reported separately in the applicable services classification; the production of raw materials used in the manufacturing of the above articles which is to be reported separately in the classification applicable to the production process used; and establishments engaged in the manufacture of watches which are to be reported separately in classification 3602-09.

A radio set is comprised of an input circuit for tuning in to the frequencies of the various transmitters to be received, the demodulation circuit for separating the audio-frequency from the high-frequency carrier, a low-frequency amplifier stage, and the loudspeaker. The amplifier elements are transistors supplied with the necessary operating voltages. Establishments in this classification usually assemble radio component parts and circuit boards that are manufactured by others. The assembly is accomplished by soldering, clipping, riveting, and welding the parts into place. This is a shop or plant only classification.

Applies to establishments engaged in the manufacture of electrical or gas-filled bulbs or tubes such as, but not limited to, incandescent lamps, photoflash lamps, flood lamps, fluorescent tubes, X-ray tubes, cathode-ray tubes, neon tubes or artistic style neon tube signs that are not attached to metal backings. The processes and equipment will vary somewhat depending on the type of electrical bulb, tube, or lamp being made, but the basic operation is the same. Component parts such as, but not limited to, glass bulbs, globes, or tubes, tungsten wire, metal bases, shellac, and nitrogen and argon gas are purchased from outside sources. Using flange machines, the bottom of the glass tubing is fused to the flange to produce the base that is used within the bulb or globe. Metal bases may be milled, and then coated with a sealing compound such as shellac. Mounts are assembled and inserted into the flange on stem machines. The assemblies are seared together, and then the tungsten filaments are fixed between support wires forming the stem. The bulbs or globes are flushed with nitrogen to expel any moisture before the stems are inserted into them. These units are inserted into the metal bases and cemented. Air is evacuated and argon gas is pumped into the bases, after which they are heat sealed and trimmed. Neon tube signs or displays are made by heating a thin tube of glass over a ribbon flame until the tube becomes flexible, blowing air into the tube to keep the glass from collapsing, then, while it is still hot, bending it to shape. Because the glass cools rapidly, the heating and bending is repeated until the desired shape is achieved, then the tube is filled with neon or argon gas and the ends sealed.
