Granted: 1995-09-05
Abstract: A frost control system is described for inhibiting and removing frost from the door (8) of a storage locker. Relatively cool air is received by an inlet to the frost control system at an inlet placed above the door. The air is drawn into the system by a blow-er (18a, 18b) which forces the air through the ducts (26, 28) of the system. The air passes through strip heaters (30, 32) within the vertical ducts (26, 28) of the defrost system positioned on either side of the door (8). The warm air is discharged horizontally ac-ross the bottom portion of the door and simultaneously rises creating a blanket of relatively warm air in comparison to the am-bient area. Discharge apertures (36, 28) are included in the ends of the vertical ducts (26, 28) which blow a portion of the warmed air to the base of the door (8) to enhance coverage of the door by the warmed air.

Patent CA-2127702-C (CA)
Inventor: KAGAMI NOBUYUKI
IPC: C08J5/18
Filed: 1993-11-10
Granted: 2000-11-07
Abstract: The present invention is polyester composition containing crosslinked polymer particles with ester bands at the main chain. The particles are excellent in affinity to polyesters, and so the films formed from the polyester compositions are hard to cause the particles to fall off during; high speed running, and hard to flaw the film surfaces by the particles. Therefore, the present invention can prevent the generation of white powder and the flawing of magnetic faces caused by falling-off particles, and prevent the contamination in the production of films, even though these are problems caused when various conventional particles are added, and is especially suitable for use as products such as magnetic films.

Title: Manganese dioxide positive electrode for rechargeable cells, and cells containing the same
Inventor: TOMANTSCHGER KLAUS
IPC: H01M50/491
Filed: 1994-02-28
Granted: 1999-03-16
Abstract: This invention teaches rechargeable manganese dioxide cells (10,40) having alkaline electrolytes, zinc negative electrodes (14) and manganese dioxide positive electrodes (18).  In keeping with the present invention, the positive electrode is essentially unconstrained - that is, no cage is used in the cell to confine the positive electrode.  During discharge of a rechargeable alkaline cell, the positive electrode may be inclined to contract or reduce its dimensions.  However, the positive electrode is dimensioned so as to substantially fill the entire space allotted for it within the cell, while allowing for a slight accomodation for height-wise or longitudinal expansion or growth in bobin cells.  The positive electrode may include additives such as carbon or graphite to increase its electrical conductivity, and hydrophobic agents such as PFTE, polyethylene or polypropylene to enhance the hydrogen permeability of the positive electrode and thereby lead to increased hydrogen recombination rates.  Moreover, the discharge capacity of the negative electrode may be established so as to be in the range of from about 60% to about 120% of the theoretical one electron discharge capacity of the positive MnO2 electrode.

Abstract: A transaction evidencing system includes a personal computer (PC) comprising a processor, memory and hard drive, with a plurality of non-metering application programs that selectively run on the PC. An unsecured printer is operatively coupled to the PC for printing in accordance with the non-metering application programs. A portable vault card that is removably coupled to the PC is programmed to generate tokens generation and perform transaction accounting. An application interface module in the PC, which interfaces with the non-metering application programs, issues a request for one digital tokens in response to requests for indicia from a non-metering application program. A secure communications module in the PC, which securely communicates with the vault card when the vault card is coupled to the PC, sends the request for digital token to the vault card and receives a digital token generated by the vault card. An indicia bitmap generation module generates an indicia bitmap in the PC from the digital token and stores it in memory. The indicia bitmap is accessed by the non-metering application program when a print indicia operation is selected. A transaction capture module in the PC stores on the hard drive a transaction record corresponding to each issued digital token and associated postal data. The application interface module, the secure communications module, the indicia bitmap generation module and the transaction capture module are part of a dynamic link library module in the PC.
