Abstract:
Coil bobbins are disclosed having flanged coil support portions provided with outboard terminal housings projecting beyond the flange rim and defining inwardly extending terminal-receiving cavities. The end walls of the housings are slotted to allow a wire to pass through the cavity in a circumferential direction relative to the winding axis in similar fashion to a turn of coiling. Bifurcated terminals pressed into the cavities in straddling relationship to the wire provide connections to the coil.A double bobbin has twin flanged coil support portions with bridging sections maintaining their physical separation. Terminal housings are provided on the bridging sections allowing wire to be first wound into a coil on one support portion, guided across the bridging section and passed through the cavity in a terminal housing, and then wound into a coil on the other support portion, all without interruption.
Abstract:
This luminaire has a reflector of substantially transparent material that is adapted to surround a light source. The reflector has many double-reflector right-angle prisms on its outer surface, each characterized by having two reflecting surfaces disposed to effect total internal reflection of a large percentage of the light from the source entering the prism. For controlling the amount of light passing from the source through the prismatic outer surfaces of the reflector, an additive in particle form is dispersed within the transparent reflector material and serves to divert some of the light rays entering the prisms into paths that intersect the reflecting surfaces at angles less than the critical angle of incidence, thereby causing said diverted rays to pass through the prismatic outer surface.
Abstract:
This luminaire comprises a metal housing surrounding an internal space and having a mouth at the front side of the housing. Within the housing is a double-ended lamp comprising a tube of transparent material and terminals at opposite ends of the tube. Also within the housing is a pair of sockets, each comprising contact structure for receiving one of the terminals and a ceramic support for supporting said contact structure. A ceramic reflector partially surrounds the tube. This ceramic reflector and the ceramic supports of the sockets constitute portions of a single integral ceramic piece that is adapted to be inserted through said mouth into said internal space as a single unit during assembly of the luminaire.

Abstract:
Felt gasket material comprising polyethylene terephthalate fibers and suitable for use in luminaires is provided with improved compression recovery properties at elevated operating temperatures of the luminaire by heating the gasket material preferably in the range of 160.degree. C to 200.degree. C for a sufficient time to heat-set the fibers.
