Abstract: A luminaire of the direct lighting type includes a fluorescent lamp for emitting a torodial light pattern to a reflector assembly having a plurality of flat and contiguous facets spaced laterally from the lamp. The reflector functions to reflect the torodial light pattern within parallel light distribution zones. The reflector may be of the cross-beam type (FIGS. 1-4) or down-beam type (FIG. 5). The facets are precisely positioned relative to the light source to provide the above functions whereby the luminaire will function efficiently and will closely control direct and reflected glare. A louver-lens assembly can be utilized to enclose the open bottom of the luminaire and to aid in these functions, a method is also taught for plotting the precise positions of the facets.

Abstract: The present invention provides a plastic support, for an electric lamp and for the enclosure for that lamp, which is resistant to flame, heat, cold, water, ice, sunshine and other natural environmental conditions; and that support makes it possible to eliminate the traditional metal mounting pan, length of metal pipe, and securing fittings. As a result, the support of the present invention can directly engage a wall rather than engage a metal mounting pan which must engage that wall, and the flexible conductors from the socket can be given a random orientation from that socket to the power-supplying conductors in the wall instead of having to assume the fixed orientation imposed by the use of a length of metal pipe. This means that the conductors can be shorter than normal; because of the elimination of the depth of the metal mounting pan, and also because the wires assume orientations comparable to hypotenuses rather than orientations resembling the altitudes and bases of triangles.

Abstract: An non-lubricated, ringless piston engine without a conventional heat exchange system having a cross-head guide for guiding and restraining the piston within a cylinder of a two-stroke engine. The piston-bore radial clearance gap is maintained during engine operation by means of a capacitance sensor controlling a temperature equilibrium flow system within the piston head and the cylinder jacket. The engine operates at high speeds to minimize horsepower losses due to gas leakage, while benefiting from reduced friction losses resulting from absence of piston rings. Blowing gases are collected and returned to the combustion chamber from a pumping chamber formed beneath the piston and above the cross-head guide.

Abstract: A throttle valve adjuster with which a quantity of air supplied to an internal combustion engine during idling, for instance, can be adjusted. The adjuster comprises a stator which is supported within a throttle valve pipe and which is rotated by actuation of a driving pedal. Supported inside the stator is an armature, which is firmly connected to the throttle valve. Located on the stator is a coil winding, which initiates a magnetic flux that acts upon the armature via two oppositely disposed guide shoulders which forms between the armature air gaps and the guide shoulders. The armature rotates relative to the stator counter to the force of a spring. The entire rotational movement of the throttle valve is thus a combination of the relative movement between the stator and the throttle valve pipe and the relative movement between the armature and the stator.

Abstract: A glare control lamp and reflector assembly and method for glare control which includes a conventional lamp and symmetrical reflector for providing a controlled light beam to a target area. A reflector shield can be positioned on the reflector below the lamp and has the properties of diverging incident light downwardly towards the target area and thus controls reflection upwardly which would produce glare. A glare shield can be positioned on the top of the reflector and extends outwardly from the outer edge of the reflector to block both direct light and reflected light from traveling upwardly and outwardly which would produce glare. In a further combination, a lamp shield can be positioned over a portion of the outermost extending end of the lamp to prevent unreflected light from directly causing glare.

Abstract: In order to avoid the need to expose a coolant level control pump to hot and/or near boiling condensate the radiator is disposed at a level higher than the coolant jacket and gravity is used to return the condensate to the coolant jacket. A level sensor in the coolant jacket senses the coolant level and energizes the pump to induct cool coolant from a reservoir in the event that the level is found inadequate. The cooling circuit can be vented to the atmosphere in order to drop the excess coolant which is introduced into the system during non-use periods to the required level to speed engine warm-up following a cold engine start.

Abstract: This invention concerns a coolant system for a vehicle which possesses a radiator and an excess coolant reservoir to reduce the content of oxygen in the radiator cooling system. An exhaust vent tube communicates with ambient air and the excess coolant reservoir to expel gases generated during engine startup and continuous use. A vacuum exhaust valve is situated in the exhaust vent tube to provide for the expulsion of gas and acts, during engine cool down, to pass exhaust gas to the excess coolant reservoir. This invention situates an adsorption zone, preferably comprised of activated carbon, intermediate the exhaust vent tube and the excess coolant reservoir to adsorb a large quantity of the oxygen being passed to the excess coolant reservoir during cool down periods. Once spent of its adsorption qualities, the adsorbent in the adsorption zone is regenerated by contact with automotive engine exhaust gas at a temperature of between 140.degree. C. and 150.degree. C.
