Abstract: The invention is an electrochemical battery cell, such as a Li/FeS2 cell, with a nonaqueous liquid electrolyte having a solvent with a high ether content and a solute including LiI and one or more additional salts, preferably LiCF3SO3, that can avoid a sharp drop in voltage on high rate and high power discharge at low temperatures, while still providing reasonable capacity on high rate and high power discharge at room temperature. The electrolyte solvent includes 1,3-dioxolane and 1,2-dimethoxyethan in a volume ratio greater than 45:55 and less than 85:15. When the total solute concentration in the electrolyte is low (0.40 to 0.65 mol/l solvent), the solute contains at least 35 mole percent LiI, and when the total solute concentration in the electrolyte is high (greater than 0.65 to 2.0 mol/l solvent), the solute contains less than 35 mole percent LiI.

Abstract: The invention is an electrochemical battery cell, particularly a Li/FeS2 cell, with a nonaqueous electrolyte. The electrolyte has LiI as a primary solute and a solvent including a relatively high level (45 to 80 volume percent) of 1,2-dimethoxyethane and a limited amount (5 to 35 volume percent) of 3-methyl-2-oxazolidinone. The inclusion of 3-methyl-2-oxazolidinone in the electrolyte provides an electrochemical cell which is economical to produce and has good discharge characteristics at room temperature, particularly on high rate and high power discharge, while also providing useful capacity at low temperatures.

Abstract: The invention is a 1.5 volt primary electrochemical battery cell with an alkali metal lithium negative electrode (such as lithium), a positive electrode (comprising iron disulfide for example) and a nonaqueous electrolyte. The electrolyte has a solute including lithium iodide dissolved in an ether-containing solvent including a 1,2-dimethoxypropane based solvent component and no more than 30 volume percent 1,2-dimethoxyethane. When 1,2-dimethoxypropane is used to replace at least most 1,2-dimethoxyethane in the solvent, the cell provides good discharge capacity at low temperature while maintaining excellent discharge capacity at room temperature.

Abstract: An apparatus for executing fixed width instructions in a multiple execution unit system has a means for fetching instructions from memory, and a decoder for decoding each fetched instruction in turn. A determination is made as to whether each decoded instruction includes a portion to fetch a locally stored instruction from a local store. If it does, the locally stored instruction is fetched and locally stored portion are executed.

Abstract: A new class of low flammability solvents for use in the electrolyte of a nonaqueous battery comprising a compound of the general formula ##STR1## in which R is a C.sub.1 -C.sub.10 alkyl group, X is a C.sub.1 -C.sub.8 acyclic group which can be linear, branched, saturated or unsaturated and Y is a C.sub.1 -C.sub.10 alkyl group or a carbonyl group O ##STR2## in which R' is a C.sub.1 -C.sub.10 alkyl group. When Y is a carbonyl group a class of diesters is disclosed which are prepared from a dihydroxy alcohol and two molecules of a monocarboxylic acid. When Y is a C.sub.1 -C.sub.10 alkyl group a class of ether-esters is disclosed. The preferred solvents are ethylene glycol diacetate and 2-ethoxyethylacetate. The solvents are preferably used in combination with a cosolvent such as propylene carbonate and most preferably employ additions of more volatile ether cosolvents such as dimethoxyethane or 1,3-dioxolane for increased discharge performance.
