Abstract: A method and system are provided for starting a combustion system utilizing a catalyst, and at the same time provide low emissions of unburned hydrocarbons and carbon monoxide. The method is particularly applicable to starting such combustion systems which are subject to intermittent operation, such as for example, gas turbines used to power automotive vehicles in which carbonaceous fuels are combusted to provide the motive fluid, or furnaces which are used intermittently. In the method, heat, such as produced by electrical means or by thermal combustion of a carbonaceous fuel, is employed to bring the catalyst to an operating temperature which will permit rapid oxidation of the carbonaceous fuel. When the catalyst has been heated to reach such operating temperatures, the start-up heating may be terminated and the normal operation of the combustion zone including the catalyst may proceed.

Abstract: A refrigerating fluid which has passed through the cooler of a refrigerating apparatus during the defrosting cycle and is thus partially liquid and partially gaseous, is fed under pressure into a heat exchanger containing a radiator and a plurality of expansion tanks. The refrigerating fluid in the combined gaseous and liquid state is fed into the evaporating tank about which hotter air is circulated by means of an air circulating fan which causes warm air coming from the radiator to be circulated about the tanks, thus causing an increase in temperature of the fluid causing it to evaporate and leaving no remaining liquid as the fluid leaves the evaporating tanks. The gaseous fluid is then directed to the compressor by which it is fed into a radiator where it tends to heat the radiator, thus providing the warm air for circulation over the evaporator tank.

A lubricant is contained in a sump in the compressor casing and it is atomized and mixed with refrigerant gas which leaks past the pistons. A duct is formed in the casing for conveying the mixture of refrigerant gas and lubricant from the casing under the action of the suction stroke of the pistons. The mixture is delivered at the inlet for refrigerant gas and the total mixture now flows to a separator where the lubricant is separated from the refrigerant gas. The refrigerant gas is then supplied into the cylinder bores during the suction stroke and the lubricant is delivered into a reservoir where it is forceably delivered back into the casing to the sump.

Abstract: A refrigeration system in which refrigerant liquid is cooled by self-evaporation and is used for refrigerating in the liquid form, in which the self-evaporation is in stages, each having a vapor compressor, the expansion taking place in enthalpy converting liquid turbines instead of permitting partial vaporization through valves into vapor separators. The enthalpy converting liquid turbines are much more efficient than the adiabatic liquid expansion which is customarily used in refrigeration systems in which a cold liquid cooled by the expansion is evaporated to absorb heat and thus to provide cooling. There is much less irreversibility and hence increase in entropy is reduced, especially when removal of super heat from the compressed vapors in each stage is effected by quenching with a small portion of the refrigerant liquid. A good portion of this heat is recovered as mechanical energy in the enthalpy converting turbines.
