摘要： An integrated system to provide both heat and electric power. The integrated, or cogeneration, system operates with an organic working fluid that circulates in a Rankine-type cycle, where the organic working fluid is superheated by a heat source, expanded through an involute spiral wrap (scroll) expander such that the organic working fluid remains superheated through the expander, cooled in a condenser, and pressurized by a pump. Heat exchange loops within the system define hot water production capability for use in space heating and domestic hot water, while the generator is coupled to the scroll expander to generate electricity.

摘要： A novel method of preparing a highly homogenous spinel Li.sub.1+X Mn.sub.2-X O.sub.4+Y intercalation compound having a predetermined mean particle size and particle size distribution for 4 V secondary lithium and lithium ion cells is provided. The method comprises mixing at least one manganese compound having a predetermined particle size distribution with at least one lithium compound wherein the manganese compound has a mean particle size of between about 1 and 15 microns and the mean particle size of the lithium compound is less than that of the manganese compound. The mixture is then fired in one or more firing steps within specific temperature ranges to form the Li.sub.1+X Mn.sub.2-X O.sub.4+Y intercalation compound. Preferably, at least one firing step is at a temperature of between about 700.degree. C. and 900.degree. C. The Li.sub.1+X Mn.sub.2-X O.sub.4+Y intercalation compounds may be used in the positive electrodes of secondary lithium and lithium ion cells to provide cells having high specific capacity, cycleability, and charge-discharge rate capability.

摘要： The device includes an audio signal circuit having two separate terminals that are connected through the photoresistor elements of two, separate, optical isolators with an audio signal input/output terminal, so that signals can be routed selectively and bidirectionally along separate signal paths to or from the input/output terminal to one or both of the two separate terminals. A separate control circuit supplies DC power selectively to the LED's which control the selective energization of the photoresistor elements of the optical isolators, the advantage being that the photoresistive devices permit selective blocking of the audio signal paths without physically opening or interrupting the paths and thus avoiding objectionable signal spikes and consequent loud popping sounds in associated loud speaker systems. The DC control circuit includes two, manually operable double pole, double throw switches for controlling the selective routing of signals between the audio signal terminals.

摘要： A process is described for the production of a stable dispersion of a copolymer, in particular of a copolyester, copolyamide or copolyesteramide, in a non-solvent organic liquid. The process involves the steps of (1) dispersing two or more comonomers, each of which is capable of undergoing homopolymerization and is solid at the copolymerization temperature, in the liquid with the aid of a defined monomer-stabilizing agent and so as to produce monomer particles no larger than 50.mu., and (2) heating the dispersion so obtained so as to bring about copolymerization, in the presence of a defined polymer-stabilizing agent. The copolymers so produced are believed to be different in structure from those obtained from the same comonomers by melt or solution copolymerization.
