Patent CA-2152628-A1 (CA)
Inventor: TOWNSEND PAUL DAVID
IPC: G09C1/00
Filed: 1993-12-23
Abstract: A method of communication uses quantum crytogra-phy to encode and decode a signal. A key is distributed on a quantum channel, and information subsequently com-municated between the transmitter (1) and receiver (2) on a public channel to determine whether the key has been inter-cepted. A common transmission medium (3) is used for the quantum channel and public channel. A calibration signal is transmitted over the public channel on the common trans-mission medium to calibrate the system for the subsequent transmission of a key on the quantum channel. The transmis-sion medium may be an optical fibre and the transmitter may switch between a single-photon output and a multiple-photon output to provide the quantum channel and public channel respectively.

Title: Gasification process combined with steam methane reforming to produce syngas suitable for methanol production
Inventor: FONG WING-CHIU FRANCIS
IPC: C01B3/36
Filed: 1995-11-23
Abstract: An improved method for the production of stoichiometric ratioed syngas comprises partially oxidizing a gaseous feedstock containing substantial amounts of methane in a gasifier to produce a hot synthesis gas stream that is passed in indirect heat exchange through a steam reforming catalytic reactor. A portion of the steam reforming reaction products are mixed with the cooled gasifier synthesis gas stream exiting the steam reforming catalytic reactor to form a combined synthesis gas stream, called a "stoichiometric ratioed synthesis gas." The stoichiometric ratioed synthesis gas stream can then be passed into a methanol synthesis unit at substantially the specifications for optimal methanol production with little or no external compression. In a second embodiment the gasifier unit is arranged and operated in parallel with a primary steam reformer unit. The respective synthesis gas streams exiting each unit are combined to form a combined synthesis gas stream that undergoes oxidation in a secondary catalytic reformer unit to form a stoichiometric ratioed synthesis gas that requires minimal external compression before being converted to methanol.

Title: Conductive agent and non-sintered nickel electrode for alkaline storage batteries
Inventor: YANO MUTSUMI
IPC: C01G51/04
Filed: 1997-02-06
Abstract: A non-sintered nickel electrode for use in alkaline storage batteries is provided. An active material of the electrode takes the form of composite particles consisting of grains of nickel hydroxide or grains mainly constituted by nickel hydroxide, each of which has a surface formed with an electric conduction layer consisting of a cobalt compound containing 0.1 to 10 % by weight sodium. The electrode is thereby adapted to make an active material available in a high degree because the pulverulent active material consists of grains, each of which is coated with an electric conduction layer having a high electric conductivity. Because the electrode is non-sintered, the highly porous substrate allows an active material having a relatively large bulk density to be used during manufacture. The presence of sodium in the electric conduction layer improves specific electric conductivity of the electrode relative to other non-sintered nickel electrodes.

Title: Device and method for testing vehicle shock absorbers
Inventor: MUELLER ROLAND
IPC: G01M17/04
Filed: 1995-09-11
Abstract: In known devices for testing vehicle shock absorbers, the tires, which have a dampening effect, are not taken into account, so that the measurement results may be falsified by up to about 30 %, depending on the tire pressure. In addition, when the wheels are mounted on the vehicle, no shock absorber characteristic curve may be measured, only individual values. In the disclosed device, the actuating variable "tire" is eliminated by a regulation process that consists in normalising the resonance amplitude, a considerably more accurate measurement being thus obtained. In addition, the spring constant of the wheel suspension is determined before actually testing the shock absorbers, allowing defective springs to be detected. Finally, car body oscillations may also be determined, causing an additional precision gain. For the first time it becomes possible to determine a shock absorber characteristic curve without having to dismount the shock absorbers.
