Abstract: A refrigerator includes an outer cabinet and an inner liner separated by insulation. The liner includes a plurality of walls defining a compartment to receive items to be refrigerated. An electric light is positioned adjacent to a first of the liner walls. A second of the liner walls disposed perpendicular to the first wall has three spaced apart slots positioned closer to the first wall than the light to the first wall. A shield is positioned between the light and the first wall and includes three tabs received in the slots in the second wall. The middle tab has a pair of lateral ears with rest positions angled with respect to the long axis of the corresponding slot. The ears flex as the tab is inserted through the slot and then return to their rest position to overlie the second liner wall. The other tabs also are angled with respect to their slots to firmly engage the second wall when installed.

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.

Abstract: A light bulb assembly includes a light bulb, a base receiving the light bulb, and a socket receiving the base. The base is formed with a displaceable arm terminating in a locking element. The socket is formed with an opening through a wall having an edge adapted to receive the locking element to lock the base to the socket. The base is releasable from the socket by passing a pointed implement through the opening to displace the finger and thereby to release the locking element.

Abstract: Disclosed is a distress signal lamp assembly including a mounting base, which has a clamping frame and vacuum mounts for mounting on either door window or any smooth surface of an automobile alternatively, a cylindrical casing fastened to a top socket on the mounting base, a retractable tube made to slide in and out of the cylindrical casing, and a lamp head fastened to the retractable tube by a toggle joint.

Abstract: The illumination device comprises a housing, a lampholder, a reflector and an electric lamp having a base rigidly connected to its light-diffusing lamp vessel. A light source within the lamp vessel is disposed substantially coaxially with an optical axis of the reflector. The reflector is polygonal in cross sections transverse to its axis and shapes the light generated into a beam, the intensity of which increases from I.sub.o along the optical axis to a value of 105 to 130% thereof at an angle of 5 to 25% to the axis. Scenes illuminated by the device yield evenly exposed photo, film and video images.

Most preferably the lamp shade is defined by two or more spaced arrays of light deflectors. In one embodiment the light deflectors are mounted end to end to allow vertical variation in light intensity and direction. In another embodiment the light deflectors are both horizontally and vertically disposed to increase versatility in both appearance and lighting effect. Thus, the lamp shade advantageously allows the light to be directed in accordance with the particular area in which the light fixture is placed, both to shield the user's eyes and to direct light where it is most needed.

Abstract: A reflector assembly for fluorescent luminaires. The reflector assembly improves the lumen output of the fixture by bringing light from the backside of the lamps around the lamps and out of the luminaire. Access to the ballast of the luminaire is improved by providing a removable section of the reflector assembly located over the ballast.

Abstract: A system for precisely measuring the amount of oil consumed during operation of an internal combustion engine includes a float chamber which communicates with an oil sump in the engine. A float is disposed within the chamber which moves upwardly and downwardly therein, depending upon the level of oil. A precision level detector is mounted in the upper end of the chamber for generating an electrical signal which is representative of the position of the float within the chamber. A microprocessor receives this signal, along with signals from various other sensors representing engine speed, engine torque, and oil temperature. In response thereto, the microprocessor controls the operation of a pump connected between an external supply of oil and the engine sump. When predetermined conditions are met, the microprocessor activates the pump to add oil from the system. The microprocessor also records the oil level over a period of time to determine the rate of oil consumption.
