In a sodium sulphur cell, improved protection of a cathode current collector is obtained by isostatically pressing graphite foil or flakes onto the surface of the collector, which surface is preferably roughened or coated with an intermediate conductive layer such as a nickel-chromium alloy or a conductive carbide providing a rough surface.

The present invention comprises a technique for performing a reassembly assist function that enables a processor to perform packet reassembly in a deterministic manner. The technique employed by the present invention enables a processor to reassemble a packet without having to extend its normal processing time to reassemble a varying number of fragments into a packet. The invention takes advantage of the fact that the reassembly assist can be dedicated exclusively to reassembling a packet from a series of fragments and thereby offloading the reassembly process from the processor.

A processor complex architecture facilitates accurate passing of transient data among processor complex stages of a pipelined processing engine. The processor complex comprises a central processing unit (CPU) coupled to an instruction memory and a pair of context data memory structures via a memory manager circuit. The context memories store transient “context” data for processing by the CPU in accordance with instructions stored in the instruction memory. The architecture further comprises data mover circuitry that cooperates with the context memories and memory manager to provide a technique for efficiently passing data among the stages in a manner that maintains data coherency in the processing engine. An aspect of the architecture is the ability of the CPU to operate on the transient data substantially simultaneously with the passing of that data by the data mover.

A high temperature rechargeable electrochemical power storage cell comprises an anode compartment containing a molten alkali metal anode; a cathode compartment containing an alkali metal aluminium halide molten salt electrolyte as well as a cathode which comprises an electronically conductible electrolyte-permeable porous matrix which has dispersed therein an active cathode substance, with the matrix being impregnated with said molten electrolyte; a separator separating the anode compartment from the electrolyte; and a wick in the anode compartment to enhance contact of alkali metal with the separator in the anode compartment. The wick comprises a layer of alkali metal wettable particles on the separator surface, and a metallic anchoring component abutting the wettable particles and protruding into the anode compartment.

The present invention comprises a scheduling assist function (scheduling assist) that enables a processor to schedule events and be notified when these events expire. In addition, the present invention includes features that enable a processor to associate these events with output channels and enable the processor to quickly locate output channels (links) that are available and ready to be serviced. The invention takes advantage of the fact that the scheduling assist can be dedicated exclusively to scanning tables in its own dedicated memories looking for events that have expired and/or output channels that are available and not involve the processor in the search for output channels that are available and ready to be serviced.
摘要:
A system and technique facilitate fast context switching among processor complex stages of a pipelined processing engine. Each processor complex comprises a central processing unit (CPU) core having a plurality of internal context switchable registers that are connected to respective registers within CPU cores of the pipelined stages by a processor bus. The technique enables fast context switching by sharing the context switchable registers between upstream and downstream CPUs to, inter alia, force program counters into the downstream registers. In one aspect of the inventive technique, the system automatically reflects (shadows) the contents of an upstream CPU's context switchable registers at respective registers of a downstream CPU over the processor bus. In another aspect of the invention, the system redirects instruction execution by the downstream CPU to an appropriate routine based on processing performed by the upstream CPU.
摘要:
A method of making a cathode for a high temperature rechargeable electrochemical cell comprises impregnating a mixture, in granular form, of an alkali metal halide and a substance comprising a transition metal selected from the group consisting of iron, nickel, cobalt, chromium, manganese, and mixtures thereof, with an alkali metal aluminium halide molten salt electrolyte. The impregnated mixture is subjected to at least one charge cycle in a high temperature electrochemical cell in which the impregnated mixture forms the cathode and is located in a cathode compartment of the cell. The cathode compartment is separated from an anode compartment by a solid electrolyte separator. Alkali metal forms in the anode compartment during the charge cycle.

This invention provides a method of making a cathode for a high temperature rechargeable electrochemical cell. A mixture is formed in particulate form of an alkali metal chloride such as sodium chloride and a substance comprising a transition metal such as iron, and the mixture is impregnated with a chloride ion-containing alkali metal aluminium halide molten salt liquid electrolyte such as molten sodium aluminium chloride. The impregnated mixture is then subjected to at least one charge cycle in a high temperature cell in which it forms the cathode and is separated from an alkali metal anode by a solid electrolyte separator.
