Abstract: A trouble light is provided which has an insulating housing and male prongs extending from one end of the housing and shielded by an extension of the housing. There is no conventional wired-in drop cord on the trouble light. Instead, an extension cord has a female socket and the aforesaid prongs on the housing are plugged into the extension cord female socket. A flexible retainer strap interconnects with the extension and is anchored on projections on the housing to prevent inadvertent disconnection of the extension cord from the trouble light.

Abstract: A light concentrator, preferably for use with a color optical scanning device includes a reflector (34) with parabolic reflecting walls (36). Green LEDs (22), red LEDs (24), and blue LEDs (26) are situated at the base of the reflector (34) and a diffuser (30) is attached to the opposite end thereof. An electric switch (32) controls the LED array. When an input page is scanned, the switch (32) activates one type of LEDs at a time. The reflector (34) concentrates the emitted light at the surface of the diffuser (30). The photodetector array of the xerographic device receives three monochromatic images which are then superimposed to provide a color image.

Abstract: A lubrication applicator presses a block of solid lubricant against the flange of a locomotive wheel. An applicator nozzle loosely fits over the body of the applicator and lightly engages the block of lubricant to bridge the gap between the body and the wheel. The applicator is supported by a main bracket fixed to an unsprung portion of the locomotive truck, such as a journal box or a traction motor, and an adjustable bracket which establishes a good attitude of the applicator and is movable radially of the wheel to accommodate wheels of different diameters. A bracket attached to a journal box fits in a restricted space between the truck frame and the wheel and comprises a plate with upper and lower channels attached to opposite sides to provide strong and light structures subject to minimal inertial loading in a severe vibrational environment. To lessen the inertial forces the brackets angle upward (rather than horizontally) to position the applicator within about 45.degree.

Abstract: Illuminated jewelry connectable to a wearer as an earring, a clothes pendant or the like includes a light-emitting diode (LED) connected onto an enlarged flat base member at one end of an elongated stem. A miniature battery housing also includes a stem cavity positioned immediately adjacent and generally coextensive with the battery compartment to supportively receive and releasably retain the distal portion of the stem therewithin. The stem and housing are structured so that an electrical circuit is completed between the battery and the LED through the stem when the stem is fully inserted to the bottom of the stem cavity. In this configuration, a gap between the enlarged base member and the housing generally equal to the thickness of the wearer's earlobe or article of clothing is defined. A transparent lens over the LED may be provided to enhance decorative illumination.

Abstract: A plug-in fluorescent lamp assembly including a lightweight (e.g. plastic) light box that is adapted to either rest upon the existing support grid of a conventional false ceiling in a flush mounted arrangement or be attached directly to the ceiling in a surface mounted arrangement. The lamp assembly comprises a prewired electrical receptacle that is fixedly connected to the light box. Formed at one end of the receptacle is a socket at which the pins of one or more fluorescent tubes are to be removably received. Located at the opposite end of the receptacle is a terminal block that is to be detachably connected to a commercially available electronic ballast by which to drive the fluorescent tubes. By virtue of the plug-in or modular characteristics of the lamp assembly herein described, either a fluorescent tube and/or the ballast may be easily removed and quickly replaced in the event of failure without having to remove the light box from the ceiling or disturb the wiring of the receptacle.

Abstract: A modular lighting system includes a line of lighting fixtures with various body, lens, lamping system and mounting system alternative configurations, types and sizes. Many of the lighting system components are interchangeable among the different lighting fixtures. Others of the lighting fixture components can be fabricated by providing a blank with a certain configuration, (e.g., a hemispherical body) and separating it into one or more components forming portions thereof. A method of forming such modular lighting fixtures includes the steps of providing such interchangeable components and providing other components which can be formed from common blanks, mounting such fixtures with various mounting fixtures and lamping such fixtures with various electrical lamping systems.

Abstract: The invention pertains to a fiber optic lamp system such as those employed in medical diagnostic systems using a cabinet containing a power supply having a front extendible drawer containing a 250 watt focused beam metal halide arc lamp mounted in a removable bracket which includes a sensing tab extension. The bracket sensing tab operates an electrical interlock switch when the proper lamp is properly installed. The interlock switch controls power to the system whose circuit includes pin and floating sleeve electrical connectors which automatically directly completes the circuit to the arc lamp upon the drawer being closed. The amount of light transferred to the fiber optic cable is optimized by offsetting the axis of focused light with respect to the optic cable axis at the cable interface.
