Abstract: The method of cleaning internal combustion engine fuel injector structure, valves and combustion chambers, and employing a canister containing a liquid mixture that includes engine fuel and injector cleaning solvent, the steps that include charging pressurized gas into the canister to a selected high-pressure level; communicating the interior of the canister with a passage extending to the injector structure and operating the engine, including a fuel pump to provide pressurized fuel discharge which is delivered to the passage; terminating operation of the fuel pump; continuing operation of the engine by allowing substantially continuous pressurized flow of the mixture in the canister to the injector structure, via the passage, and until the mixture in the canister depletes; and after pressure drops to a selected lower level, re-charging pressurized gas into the canister to a selected high-pressure level, and continuing the communication of the canister interior with the passage to flow more of the mixture to

Abstract: A method for rapid and efficient cleaning of an internal combustion engine cooling system includes forcing the coolant liquid from the cooling system to the exterior of that system, driving the coolant liquid from the cooling system to the exterior of that system, treating the coolant liquid in a zone or zones outside the cooling system, such treating including effecting precipitation of anions and cations, in the coolant liquid to produce contaminant particulate and removing contaminant particule from the coolant liquid, and returning the treated coolant liquid to the cooling system.

Abstract: A child resistant upright bottle neck and cap combination if provided, wherein threads formed on its outer side and there being structure at the uppermost end of the neck to close same, the cap having a first skirt and threading formed on the skirt at the inner side thereof to mesh with the neck threads when the cap is rotatably attached to the neck. In this environment there is provided:(a) first lug structure including a first lug on the neck and protruding sidewardly outwardly thereof,(b) and a second lug on the cap skirt and protruding sidewardly inwardly thereof to engage and ride over the first lug during rotatable attachment of the cap to the neck,(c) and a brake surface formed on the cap generally opposite the second lug and presented inwardly to engage the neck and frictionally resist cap rotation in either direction after the second lug rides over the first lug in a cap tightening direction.

Abstract: A gasoline additive composition comprising an organic peroxide and a gasoline detergent in a hydrocarbon solvent. Improvements in engine power, fuel economy, and emissions are achieved when the composition is added to gasoline.

Abstract: A water and energy conservation system connectable between a hot water line and a hot water faucet comprising a reservoir for saving clean water normally wasted as the hot water tap is turned on and the cold water retained in the hot water line between the hot water system and the faucet is drained. When the hot water faucet is turned on, the water in the hot water line is conducted into the reservoir where it accumulates until the water in the reservoir reaches a predetermined temperature. At this time, the reservoir is drained through the hot water faucet.

Abstract: An inexpensive, highly efficient, durable, and easy to manufacture solar collector of the flat-plate type. The collector includes a heat exchanger having an upper plate, a lower plate, and four triangularly-shaped side plates defining an enclosed chamber, all plates being highly absorbent of solar radiation, the upper plate curving inwardly so that a central portion thereof extends closely adjacent the lower plate along a hot line extending between opposite corners of the collector; and means for conducting a fluid into and out of the chamber, at the remaining corners thereof, on opposed sides of the hot line, so that the fluid flows through the chamber, perpendicular to and in a thin sheet past the hot line, absorbing heat from the upper plate. The collector also includes a frame in which the heat exchanger is supported along the outer edges only in a manner such that light is reflected to the lower plate to increase the efficiency of heat absorption.
