Abstract: A method of enforcing a regular manganese dioxide cathode to become gradually and substantially rechargeable is described, where the cathode capacity is increased towards the theoretical capacity of the cathode. The method involves mixing 20-51 wt% MnO2, 5-25 wt% metallic bismuth and 30-70 wt% graphite powder to form a homogenous mixture, subjecting the mixture to a pressing force to form an electrode and subjecting the electrode to successive discharge/charge cycles at a rate where the cathode capacity becomes greater than 75 % of the theoretical capacity after 4-11 cycles. The method provides for a simple and inexpensive way of forming a rechargeable manganese dioxide cathode without complex chemical synthesis.

Title: Method and apparatus for charging and discharging electric energy
Inventor: FOMINO MARINA
IPC: H01M50/77
Filed: 1993-04-13
Abstract: A method and apparatus for storing and producing electrical energy in an electrochemical cell (32), where the cathode is a porous air electrode (7) and the anode is a hydrogen-containing metal hydride (4). According to the invention, an overpressure is allowed to form inside the porous air electrode during charging, the said pressure preventing the formation of hydrogen bubbles on the metal hydride electrode.  The overpressure remains at the desired level because the pores of the air electrode are made so small that the surface tension of the electrolytic solution (6) penetrating into the pores seals the porous air electrode.

Title: Data compression method and device utilizing children arrays
Inventor: KLAYMAN JEFFREY T
IPC: H03M7/30
Filed: 1994-08-08
Abstract: 2148922 9508873 PCTABScor01 A method (700) and device (1100) increase throughput of a data compression encoder or decoder by using children arrays instead of linked lists in the building and maintenance of the tree. A children array with elements corresponding to each of the input symbols is allocated to a node. An input character is used as an index into the children array. The search result is determined by the value in the children array. Where a search is successful, the value in the children array is a pointer to the child node. A node is added by storing a pointer to the node in the parent's children array at the location indexed by the input character and is deleted by storing a NULL value in the parent's children array where the child node had been. The search, add, and delete operations become very efficient, and each operation has a constant execution time.

Abstract: A data driver circuit (25) and system driving scheme that can be integrated directly onto a display substrate (14) to induce the cost of the peripheral integrated circuits and the hybrid assembly needed by unscanned active matrix liquid crystal displays to connect them to the array. A demultiplexer circuit (102) is deposited on the display (14) for demultiplexing a group of Y columns of multiplexed video data input signals to X groups of Y pixel capacitors (94, 96...100) that are also deposited on the substrate (14) in Z rows. In addition, a data driver circuit (12) provides voltage signals to precharge the pixel capacitors (94, 96...100) to a first voltage level in a first time period such that video data input signals coupled thereto in a multiplexed fashion during a second time period cause the pixel capacitors (94, 96...100) to store to a second predetermined voltage level to provide a video display as the rows of pixels are sequentially scanned.

Title: Sidewall applicator for heat fusion of a fitting to a plastic pipe
Inventor: WELCH JOSEPH L
IPC: B29C65/20
Filed: 1995-06-12
Abstract: A sidewall applicator for heat fusion of a fitting to a plastic pipe has first and second spaced apart paralleled main shafts each having a lower end that is supported by rounding shells to the exterior of the plastic pipe so that the main shafts are supported in a plane that includes the pipe tubular axis.  A housing is slidably supported by and positioned between the main shafts.  A hydraulic displaceable force piston extends from the housing in the direction towards the pipe.  A fitting holder is removably attached to the force piston which, in turn, removably supports the plastic fitting to be secured to the pipe.  Brake arms are pivotally supported to the housing, each having an outer end that releasably engages one of the main shafts.  An actuator piston supported in the housing is in closed communication with a fluid filled passageway within the housing, the fluid passageway being in communication with the brake pistons and the force piston.  A threadably extended shaft engages the actuator piston and has a knob so that by rotating the knob the force piston is displaced applying hydraulic pressure to the fluid passageway to, in turn, displace the brake pistons and the force piston to simultaneously lock the housing to the shafts and to drive the force piston downwardly to force a fitting held thereby into engagement with the pipe.
Patent CA-2154327-A1 (CA)
Title: Instruction result labeling in a counterflow pipeline processor
Inventor: YUNG ROBERT
IPC: G06F9/34
Filed: 1995-07-20
Abstract: The present invention provides an efficient streamlined pipeline for a counterflow pipeline processor with a renaming table. The counterflow pipeline includes an execution pipe having multiple instruction stages forming an instruction pipe, a plurality of result stages forming a result pipe, and a corresponding plurality of comparator/inserters. Each comparator/inserter couples an instruction stage to a corresponding result stages. The counterflow pipeline also includes a register exam stage with the renaming table. The renaming table has entries for associating each register value of an instruction with a unique renamed register number (RRN), thereby eliminating the need for arbitration and housekeeping (killing of stale register values), as instructions and their respective register values counterflow in the streamlined counterflow pipeline. An RRN counter, such as a modulo counter, is coupled to the renaming table and provides unique RRNs for assignment to new register values. In accordance with one embodiment of the invention, instructions are decoded and unique RRNs assigned to the source and destination operand registers. If there is no previous RRN assigned to a register operand, its register value is retrieved from a register file and inserted into the top of the result pipe. In addition, when an instruction execution produces a register result value in the execution pipe, the associated RRN and register value are inserted laterally into the result pipe. The register values and RRNs, in the form of result packages, are garnered by younger (later in program order) instructions counterflowing up the instruction pipe.
