摘要:
An infrared radiation source for gas detection, with a thin layer infrared radiator that is arranged in the interior chamber of a protective housing that includes a support surface for the thin layer infrared radiator and an exit window for the infrared radiation arranged at a distance opposite the support surface. The thin layer infrared radiator includes a platinum layer and at least one structurally defined de-gassing canal with an entry opening and an exit opening that leads from the interior chamber of the protective housing to the outside. For non-critical applications, the de-gassing canal is not sealed. For critical applications, it may be sealed by a sealing membrane that is water impermeable, water vapor permeable and open for gas diffusion, with the sealing membrane preferably being semi-permeable.

A method is provided for producing an infrared emitter made of an endless quartz glass body, wherein a reflector layer is deposited at least partially on the surface of the body made of quartz glass. The quartz body is divided into individual sections after application of the reflector layer. An infrared emitter is also provided.

Manufacturing equipment and manufacturing process steps that improve upon prior art processes for the manufacturing of filament tube and arc tube light sources, their components and subassemblies, and lamps employing said light sources. A double ended, tipless filament tube or arc tube light source incorporates a drawn-down tubular body, and one piece foliated leads with spurs for process handling and for spudding into a filament with stretched-out legs. Bugled ends on the body provide a novel cutoff means, facilitate a flush-fill finishing process, and enhance mounting and support of the light sources in lamps. The foliated leads are made from a continuous length of wire in a process including foil hammering and two-bath AC electrochemical etching. Cost-reduced light source and lamp production enables affordable household consumer lamps, even when containing two series-connected halogen filament tubes. Safety benefits ensue from series connection, especially in combination with disclosed body and filament constructions.

摘要:
An incandescent lamp having a substantially cylindrical glass bulb closed at one end by an exhaust-sealed portion, the entire length of which is reduced by reducing the inclination of a portion continuing from the cylindrical major portion of the glass bulb to the exhaust-sealed portion, as well as, a process for producing the same. The glass bulb containing filaments is closed at one end by the exhaust-sealed portion, with a shoulder having a substantially truncated conical appearance connecting the exhaust-sealed portion and the substantially cylindrical major portion, wherein the angle formed between the plane orthogonal to the axis of the glass bulb and the surface of the shoulder, i.e. the inclination of the surface of the shoulder, is designed to be 45.degree.or less.
