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.
