Abstract: Absorption heat pump system and process for heating, refrigeration, air conditioning and heat transforming, employing an aqueous buffer solution of a lithium salt therein; an aqueous buffer solution of a lithium salt perfectly neutral in pH useful as a coolant, achieving a very high C.O.P. at a temperature lift much higher than usual, without danger of crystallization, even at high generator temperature (up to 330.degree. C.) and evaporator temperature as low as minus 10.degree. C., while in most cases the absorber and condenser can be economically cooled by (ambient) air.

Abstract: This invention discloses an extremely simple chemical heat pump system utilizing the chemical reaction heat of a perfectly reversible chemical disassociation reaction system wherein one gaseous compound is involved in the reversible reaction. The present system can realize a large coefficient of performance over a very attractive temperature range and level for general use, by absence of any phase transition. Reaction kinetics of the system are excellent since only one reversible non-flammable gaseous compound is involved in the chemical heat pump system. The system can be provided with a computer controlled system for changing the restriction value of the expansion valve. The system utilizes jet ejectors in combination with the compressor in the same or different loops to reduce the capacity requirements on the compressor.

The present system can realize a large coefficient of performance over a very attractive temperature range and level for general use, by absence of any phase transition. Reaction kinetics of said system is excellent since only one reversible non-flammable gaseous compound is involved in said chemical heat pump system. Said system can be provided with a computer controlled system for changing the restriction value of the expansion valve. The said system is superior to most conventional compression system by replacing the use of ozone (layer) attacking C.F.C's (chlorofluorocarbons) over the entire temperature range.

Abstract: A liquid fuel injection system for an internal combustion engine in which the fuel, gaseous under ambient conditions, is injected in liquid form under compression into the intake manifold of the engine. Fuel is controlled largely by intake manifold pressure together with the RPM of the engine. Some fuel bypasses the injector, is vaporized and fed into the intake manifold through a sleeve in sufficient amounts to maintain the engine at idle and low load conditions and prevent the injector from freezing.

Abstract: A propane supply unit for use with gasoline powered automotive internal combustion engines to replace the liquid fuel. The unit consists of a plurality of circular or otherwise formed tubular elements supplied with gas from a common manifold located within the air cleaner housing. The tubular elements are spaced so as to divide up the air flow. Openings in the elements are located as to face the spaces between the elements and discharge the gaseous fuel into the separate streams of air. The unit does not alter the normal air flow conditions so that no modification of the existing engine control system is required when the supply unit is used.
