Patent CA-2110097-C (CA)
Inventor: KAWAKAMI SOICHIRO
IPC: H01M4/40

Granted: 2002-07-09
Abstract: A secondary battery exhibiting a long cycle life and comprising a negative electrode active material made of lithium or zinc is provided, the battery at least having a negative electrode made of lithium or zinc serving as the negative electrode active material, an electrolyte (electrolyte solution), a separator, a positive electrode made of a positive electrode active material, a collecting electrode and a battery case, wherein at least the surface of the negative electrode is covered with a film having a structure which allows ions relating to the battery reactions to pass through. Since growth of dendrite of lithium or zinc at the time of the charge can be prevented, short circuit between the negative electrode and the positive electrode can be prevented. Therefore, the charge/discharge cycle life can significantly be lengthened. As a result, a lithium secondary battery, a nickel-zinc secondary battery, an air-zinc secondary battery, a bromine-zinc secondary battery and a silver oxide-zinc secondary battery of the long cycle life can be manufactured.

Patent CA-2127757-C (CA)
Inventor: MASON ARTHUR C
IPC: B23Q1/54
Filed: 1994-07-11
Granted: 1997-12-16
Abstract: A mechanical loading device capable of generating a substantially rectilinear output motion for the purpose of transporting workpieces between work stations.  The mechanical loading device is capable of producing the rectilinear output motion such that a workpiece is lifted, transferred horizontally, and then lowered into position with a significant degree of precision.  The rectilinear output motion is generated primarily by a carrier on which a yoke is supported with an eccentric shaft extending from a driven member mounted to the carrier.  The eccentric relationship between the driven member and the yoke, in conjunction with the controlled rotation of the carrier, generates the rectilinear output motion at an output member supported by the yoke.  The mechanical loading device is structurally strong and compact, is constructed so as to be readily maintainable, and enables the efficient conversion of a rotational input motion to the desired rectilinear output motion.

Title: Remote file transfer method and apparatus
Inventor: PYNE CHARLES F
IPC: H04L29/06
Filed: 1995-01-12
Granted: 2005-04-05
Abstract: Remote file transfer applications often involve a situation where a receiving computer (22) contains a reference file (48) that may be similar, or perhaps even identical to, a source file (46) to be transmitted by a sending computer (20). Disclosed is a file transfer method that identifies and isolates the differences between the two files, and transmits only those differences to the receiving computer.  The method divides the data in the reference file into a plurality of blocks and associates each block of data with a key value. The key values are then sent to the sending computer in the form of an array. At the sending computer, a block of data at the source file is identified, its key value computed, and the key value is then compared to the keys in the array. If a match is found, an indication of such is sent to the receiving computer. Otherwise, a byte of data from the data block is sent to the receiving computer. and a subsequent block of data is identified and analyzed. The latter steps of the method are repeated until a representation of the source file is present at the receiving computer.

Title: Method and device for non-interlace scan detection and field elimination

Granted: 2004-09-14
Abstract: A method for determining which of similar video fields may be excised to enhance video signal compression evaluates parameters of four successive fields denoted 0, 1, 2, and 3. Accumulated differences d(0, 2) and d(1,3) of corresponding pixels in successive frames are generated. In addition a determination is made whether fields 1 and 2 exhibit interlace characteristics. If they do not exhibit interlaced characteristics, a comparison is made of d(0, 2) and d(1, 3). If d(0, 2) is less than d(1, 3) by a predetermined amount, field 2 is excised from the signal stream and a code is generated to condition a receiver to display two of the remaining four fields in a three field interval.      Subsequently the latter two fields of the set of 0, 1, 2 and 3 fields, and the next two occurring fields are similarly analyzed.

Abstract: Refractory material is applied to the interior surface of a vessel by advancing a boom carriage on a frame positioned externally of the vessel through an opening in the vessel. The boom carriage supports a collapsed telescoping mast and a nozzle boom. The carriage supporting the mast and nozzle boom is advanced through the opening to an elevated position within the vessel. At the end of travel of the boom carriage, the telescoping mast is pivoted through approximately 90° to a vertical position and the nozzle boom is pivoted to a position perpendicular to the mast. The mast is progressively extended as the nozzle boom is rotated and refractory material is sprayed from a nozzle assembly on the end of the boom onto the vessel interior surface. The nozzle boom is transversely and pivotally movable on the mast to adjust the position of the nozzle assembly to follow the irregular contour on the interior surface as the mast is telescopically advanced or retracted.

Abstract: A brake shoe locking key is provided with a retention tab that is saw-tooth shaped and extends across the entire width of the key shank.  The retention tab is upraised from the shank more than the correspondingly-shaped serrations typically formed on the bottom of the key and is thus more effective in engaging the brake head as an initial detent to prevent the key from backing out of the keyhole in the brake head when a loose fitting key fails to retain its locking position.    In addition,  the retention tab  is adapted to engage the keybridge at the orifice through which the key passes in order to provide a further detent to prevent a loose key from backing completely out of its locking connection between the brake head and brake shoe, in the event the first detent fails to engage.
