Inventor: ALLUM DAVID R
IPC: G06Q10/08
Filed: 1993-05-18
Abstract: Mail can be sorted automatically to point of delivery level by deriving from the address including postal code on a piece of mail a suffix which together with the postal code forms routing data which uniquely identifies the final delivery address.      This is achieved automatically at the Post office sorting facility by means of an optical character reader which reads the addresses on mail items and a computer arranged to generate a suffix based on the address read. The routing data is printed as a bar code on the mail item and this allows the complete sortation to be effected automatically. Also contemplated is a progressive encoding system which can be applied as bar codes by customers as desired to mail pieces. The basic data is the routing data set to which can be added a shipment number which allows automatic revenue accounting control and a piece number which allows automatic track and trace. Finally, the customer may also progressively encode return mail envelopes with the shipment number followed by a product code and a user defined field which permits automatic specialized handling of the return mail item.
Patent CA-2098384-A1 (CA)
Inventor: SCHWAIGER KARL-HEINZ
IPC: H04L7/08
Filed: 1991-12-11
Abstract: In order to transmit additional information with an A.M. radio signal, the phase position of an A.M. radio signal carrier is first modulated on the emitter side with a digital, coded additional information signal. On the receiver side, the A.M. radio signal carrier is phase modulated, the recovered additional information signal is decoded and the decoded additional information is used for tuning, switching and/or reproduction purposes. The additional information (PI, PS, AF, AFT, TP, TA, TMC, RT) of the additional information signal is subdivided into a cyclically repetitive number of groups having each two information blocks of the same length. Each information block has an information word and a checking word composes of a determined number of data bits, different offset words being superimposed upon both checking words of each group. These offset words are used on the receiver side for synchronizing the information blocks.
Patent CA-2099376-A1 (CA)
Title: Stabilization of proteins by cationic biopolymers
Inventor: AUER HENRY E
IPC: A61K9/16
Filed: 1991-12-31
Abstract: A method is described for the incorporation of proteins in the form of specific noncovalent complexes with polycationic reagents, into sustained release systems, where the polycation stabilizes the protein against inactivation while it resides in the delivery device, and retards release of the protein from the delivery device. Alternatively, the polycation-protein complex itself serves as a depot for release of the protein active agent, rather than a polymeric matrix. The end result is the release of the active agent with retention of biological activity, with a high cumulative field, over a sustained period of time.

Patent CA-2102014-A1 (CA)
Title: Improved gfci receptacle
Inventor: MCDONALD THOMAS M
IPC: H02H3/33
Filed: 1993-10-29
Abstract: A GFCI receptacle has a receptacle and terminals for connecting the connectors of that receptacle to an AC source, terminals for connecting the connectors of the receptacle to one or more other loads and an interrupter for disconnecting the source from the receptacle and the other loads in the event of ground current exceeding a selected level. For testing the interrupter, a manually operable supervisory circuit opens the interrupter and gives a visible indication of its operation. The supervisory circuit is connected between a hot connector of the receptacle and ground so that the visible indication will not be visible when the GFCI receptacle is installed improperly, thereby avoiding a false indication of proper installation.

Inventor: SCHOOLCRAFT RALPH W
IPC: H04B1/707
Filed: 1993-11-17
Abstract: "Spread spectrum communication system" A pseudo-noise (PN) correlation and demodulation method and apparatus, in which received signals are correlated with locally generated PN codes and correlation measurements are maintained for multiple time bins corresponding to signals received over possible multiple paths. Instead of selecting one or a small number of significant correlation measurements to control data demodulation, the method of the invention performs data demodulation over the multiple time bins, and then selects data values corresponding to significant correlation measurements and combines the selected data values, weighting them in accordance with their relative strengths a determined during correlation. Use of the invention provides improved performance in terms of signal quality and continuity in the presence of multipath conditions. Careful selection of design parameters allows the improved performance to be obtained in a compact and easily portable implementation including transmitter and receiver modules.

IPC: H03L7/089
Filed: 1994-01-19
Abstract: A device for converting binary logic pulses into an output current and the output current being switchable between a positive and negative polarity. The device provides a charge pump circuit which is suitable for the phase-detector stage in a phase-locked loop (PLL) circuit. The charge pump circuit comprises an input stage for the "UP" binary logic pulses and a second stage for the "DOWN" binary logic pulses. The input stages comprise emitted-coupled transistor pairs. The circuit includes current sources and current sinks for generating the output current in the input stages in response to the binary logic pulses. The circuit features a pair of commutating diodes between the outputs of the input stages. The commutating diodes control the output current and the leakage current in the idle state.      The circuit also includes a clamping circuit to limit the voltage swing across the commutating diodes. The charge pump circuit according to the present invention exhibits a fast response time, a symmetrical response to the binary logic pulses, and virtually zero leakage current in the idle state. The charge pump circuit utilizes non-complimentary bipolar processes and is suitable for a monolithic integrated circuit implementation.
Patent CA-2116906-A1 (CA)
Inventor: BEST WILLIE H
IPC: F27D99/00
Filed: 1994-03-03
Abstract: Radiant emitting walls enclose opposite sides of a central combustion chamber in an oven where coated objects to be dried are placed or passed.   The radiant emitting walls generate primarily infrared radiation and have a nonuniform temperature distribution so that the temperature of  the  lower portion  of  the  oven  can be  selectively adjusted to be significantly higher than the temperature of the upper portion.  An insulated outer housing surrounds the radiant walls and defines combustion chambers each having a linear burner which runs substantially the entire length of the radiant emitting walls.  The lower portions of the radiant emitting walls receive energy primarily from radiation from the linear burners and the upper portions of the radiant emitting walls receive energy from primarily radiation from the interior radiant emitting surfaces of the insulated outer housing and convection from the linear burners.   The  temperature  distribution of  the radiant emitting walls can be selectively varied by varying the distance between the burners  and the  radiant  emitting walls.
