Abstract: ABSTRACT          The invention provides a method of making an electrochemical cell.  The method comprises loading, into the cathode compartment of the cell an alkali metal aluminium halide molten salt electrolyte having the formula MAlHal4 wherein M is the alkali metal of the separator and Hal is a halide; an alkali metal halide MHal wherein M and Hal are respectively the same alkali metal and halide as in the molten salt electrolyte; aluminium; and an active cathode substance which includes a transition metal T selected from the group comprising Fe, Ni, Co, Cr, Mn and mixtures thereof.  An electrochemical cell precursor is thereby made.  When the precursor is subjected to charging at a temperature at which the molten salt electrolyte and alkali metal M are molten, aluminium reacts with the alkali metal halide MHal to produce further said molten salt electrolyte and to form said alkali metal M, the alkali metal M passing through the separator into the anode compartment.  After all the aluminium has reacted with the alkali metal halide to provide a cell in a discharged state, the active cathode substance is halogenated, with further alkali metal M being produced and passing through the separator into the anode compartment, the proportions of alkali metal halide MHal, molten salt electrolyte and aluminium loaded into the cathode compartment being selected so that when the cell is fully charged and all the available active cathode substance has been halogenated, the proportion of alkali metal ions and aluminium ions in the electrolyte is such that the solubility of the active cathode substance in the molten electrolyte is at or near its minimum.

Title: Hole saw plug ejector
Inventor: PARENT PHILIP V
IPC: B23B51/04
Filed: 1988-02-02
Granted: 1992-01-07
Abstract: Hole Saw Plug Ejector Abstract Cylindrical type hole saws, as known, necessarily allow for the cut out hole plug to enter the cylinder as it is being cut and remain there when the hole saw is withdrawn from the workpiece.  Generally, this plug becomes bound within the cylinder.   In order to remove this plug, a screwdriver blade or similar slim object is inserted into one of the several slots provided in the periphery of the saw blade.  The screwdriver is then canted, thereby forcing the plug outward.  The present invention Provides for the removal of the cutout plug without disconnecting the drill motor and makes the removal faster, safer, and easier than is presently known.  Other reference devices which attempt to solve this problem utilize manual force in an attempt to dislodge the plug. Very tightly bound plugs may still present difficulty depending upon the physical strength of the user.  None of these devices utilize the novel features of the present invention.

Abstract: "Adaptive Data Compression Method and Apparatus"     Abstract of the Disclosure A method and apparatus for compressing data, particularly useful in a modem. The preferred method is implemented in a microprocessor within a modem, and dynamically adapts to changing data statistics. Parallel encoding and decoding tables are provided at the encoder and the decoder, and are updated for each character processed. Each table has a plurality of digital compression codes associated with characters of an alphabet. In response to an item of data presented for encoding, a compression code which corresponds to the character presented for encoding is selected using the encoding table. The selected compression code is provided as an output. Periodically, the association between the codes and the characters of the alphabet in the table is adjusted as a function of the frequency of occurrence of characters of the alphabet, over a plurality of characters. As the frequency of occurrence of characters presented for encoding changes, the more frequency occurrence characters become associated with the shorter codes in the encoding table. By performing the same steps in the decoding table, the compression codes are used at the decoder to select a character of the alphabet, which is provided as a decoded output.
