Abstract:
Disclosed herein is a valve. The valve includes a first member having a first port therethrough, a second member in operable communication with the first member having a sealing surface thereon on an inner radial surface of the second member and a second port therethrough that is movable relative to the first member. The valve also has a seal sealingly engaged with the first member and slidably sealingly engagable with the second member, and a support member movably disposed relative to the first member and the second member. The support member has a support surface dimensioned similarly to the sealing surface, and is movable with the second member relative to the first member so that upon such movement the seal is continuously supported by at least one of the sealing surface and the support surface.
Abstract:
A method and apparatus are provided for executing instructions of a multi-threaded processor having multiple hardware threads (32, 34) with differing hardware resources comprising the steps of receiving a plurality of streams of instructions (38, 44) and determining which hardware threads are able to receive instructions for execution (40, 46), determining whether a thread determined to be available for executing an instructions has the hardware resources available required by that instructions (36) and executing the instruction in dependence on the result of the determination (50).
Abstract:
A lithium electrochemical cell design incorporating a low molality electrolyte including LiI is disclosed. The resulting cell delivers excellent performance under a wide range of temperatures, conditions and drain rates.
Abstract:
A method and apparatus are provided for selecting between a plurality of instruction sets available to a microprocessor. An instruction fetch address is supplied. At least one predetermined bit of the instruction fetch address is used to select between the instruction sets. Once an instruction set has been selected instructions may be fetched and decoded with a decoding scheme appropriate to the instruction set.
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. Soluble salts used in the electrolyte solution are, for example, LiCF.sub.3 SO.sub.3 LiBF.sub.4. The preferred lithium salt is LiCF.sub.3 SO.sub.3.
Abstract:
A portable lift is provided. The portable lift includes a top frame assembly, a carriage frame, a base frame, and a hoist mechanism. The top frame assembly is secures top ends of a pair of stringers together. The base frame assembly secures bottom ends of the pair of stringers together forming the portable lift frame. The carriage frame includes a plurality of wheel assemblies each having a plurality of wheels. The plurality of wheels releasably retain to and slidably engage with a stringer of the pair of stringers. The hoist mechanism includes a motor, a spool rotatable by the motor, a pulley secured to the top frame assembly, and a hoist cable wrapped around the spool and running from the spool through the pulley and secured to the carriage frame.
Abstract:
A method is provided for dynamically determining which instructions from a plurality of available instructions to issue in each clock cycle in a multithreaded processor capable of issuing a plurality of instructions in each clock cycle. The method includes the steps of: determining a highest priority instruction from the plurality of available instructions; determining the compatibility of the highest priority instruction with each of the remaining available instructions; and issuing the highest priority instruction together with other instructions compatible with the highest priority instruction in the same clock cycle. The highest priority instruction cannot be a speculative instruction. The effect of this method is that speculative instructions are only ever issued together with at least one non-speculative instruction.
Abstract:
An apparatus for executing fixed width instructions in a multiple execution unit system has a device for fetching instructions from a 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:
An electrolyte composition including a detectable contrast agent and an electrochemical cell including the electrolyte composition, wherein the contrast agent allows for detection of spillage or leakage of electrolyte during or after cell construction. In some embodiments, the contrast agent is able to change the color intensity of the electrolyte composition over time after addition to the cell. Methods for detecting spillage or leakage of the contrast agent-containing electrolyte composition during cell construction are disclosed.
Abstract:
An nonaqueous electrolyte blend for improved low temperature performance in lithium-iron disulfide cells is contemplated. The electrolyte has at least two solutes, including lithium iodide, wherein the lithium iodide is present at a concentration of 0.26 to 0.45 moles per liter of solvent and wherein the overall concentration of solutes is between 0.40 and 0.75 moles of total solute per liter of solvents. The solvents include DIOX and DME provided at a ratio of DIOX:DME between 50:50 and 70:30, and the solvents must include at least 80 volume percent of ethers.
