Title: Process for expanding tobacco
Inventor: NEVETT ROBERT
IPC: A24B3/18
Filed: 1997-02-04
Abstract: Tobacco is treated to cause its expansion by a process which comprises the steps of subjecting it, in a treatment chamber, to a reduced pressure of not greater than 7 kPa, impregnating the cell structure of the tobacco with isopentane vapour at a temperature in the range of from 70 °C to 100 °C and maintaining the tobacco in contact with the vapour at a pressure of at least 400 kPa, removing excess isopentane vapour from the treatment chamber, contacting the impregnated tobacco with steam to expand the tobacco cell structure, reducing the pressure in the treatment chamber at a rate of at least 10 kPa/minute, preferably 30 kPa/minute, and then venting the treatment chamber back to atmospheric pressure. The final filling value of the tobacco treated according to this process is directly proportional to the rate at which the pressure in the treatment chamber is reduced following the steam treatment of the tobacco.

Title: Detecting digital multiplexer faults
Inventor: HABEGGER KENNETH LEON
IPC: H04L12/26
Filed: 1998-08-06
Abstract: Apparatus and a method for testing tiered digital multiplexing apparatus. To test a primary train of tiered demultiplexers, a data path assurance train of demultiplexers and a selector is used to generate a demultiplexed signal for comparison with a primary demultiplexed signal. To test a primary train of tiered multiplexers, the output of the final multiplexing stage is connected to the input of the data path assurance train of demultiplexers to generate a demultiplexed signal for comparison with a primary input signal to the primary multiplexer train. Advantageously, a simpler, more reliable, and less expensive data path assurance circuit using the same types of components as the primary multiplexers and demultiplexers can be used to detect failures in these primary units as well as the data path assurance circuit.
Patent CA-2245317-A1 (CA)
Title: Circuit card connector with isolation base assembly
Inventor: ZIELKE HENRY
IPC: H01R12/79
Filed: 1998-08-19
Abstract: A circuit card connector that utilizes flexible circuitry includes one or more isolator portions attached to its base that serve to substantially isolate the base of the connector from the circuit board to which the connector is mounted.  The isolator portions include feet that extend out from the connector and which partially support the flexible circuitry.  These isolator portions are made from thermally insulative material and serve to prevent heat transfer to the connector base from occurring during soldering of the flexible circuitry conductive portions to the circuit board.

Patent CA-2246423-A1 (CA)
Title: Encoder for digital data storage
Inventor: GRAY MARTIN D
IPC: H03M13/41
Filed: 1997-02-07
Abstract: A variable rate bit inserter is provided which efficiently encodes data prior to writing to a magnetic storage medium. In a preferred embodiment, the bit insertion technique monitors the phase and amplitude content of the data stream and inserts appropriate bit patterns to ensure that phase and amplitude lock are maintained on the data stream for reading and decoding purposes. Preferably the number of bit insertions made on a given randomized block of data is monitored to determine if the number of bit insertions falls within the tolerable limits for storing the data. If the number of bit insertions is not tolerable, the pseudo-random code used to randomize the data stream is reconfigured.

Title: Windshield stripper
Inventor: ANDELA CYNTHIA
IPC: B02C13/04
Filed: 1996-02-20
Abstract: A device for recycling automotive windshields (11). An automotive windshield is comprised of two layers of glass and a plastic liner sandwiched in between. The present invention strips the glass from surfaces of the inner plastic liner, comminutes the glass and separates the two substances for recovery. A windshield is fed into the unit (11) by means of dual horizontal feed rollers (14). The windshield then passes over a stationery breaker bar (25) and into the path of a plurality of rotating flexible impactors (26). The force of the rotating impactors (26) on the top surface and the stationery breaker bar (25) on the under surface act together to strip the glass from both sides of the inner plastic liner material. The glass is hammered into small particles the size of gravel and sand while the plastic breaks into much larger fragments. A shaker screen (43) located below the rotating impactors (26) serves to separate the two substances for individual recovery.

Le système de gestion de fibres (100) comprend des guides de fibres (101, 102) et un ou plusieurs plateaux de fibres (111a-111g). Un guide de fibre (101) comprend plusieurs taquets intérieurs (102a-102e) et plusieurs taquets extérieurs (104a-104e) pour retenir une fibre optique. L'un au moins des taquets comporte une partie courbe ayant un rayon tel que la fibre optique qui passe sur celui-ci ait une courbure qui ne soit pas inférieure à son rayon minimum. Le plateau de fibre, qui achemine une fibre optique vers le guide de fibre, comporte une lèvre courbe ayant un rayon au moins égal au rayon minimum de courbure des fibres optiques. Le plateau de fibre et le guide de fibre ont une position telle que la lèvre courbe du plateau de fibre est adjacente à la partie courbe du taquet. Les fibres optiques sont acheminées sur la lèvre courbe du plateau de fibre puis sur la partie courbe du taquet correspondant, ce qui permet de les faire courir sans les plier au-delà de leur rayon minimum de courbure.

Patent CA-2264467-A1 (CA)
Inventor: TESSIER LYNN P
IPC: E21B23/01
Filed: 1999-03-05
Abstract: A tool is provided for preventing the rotation of a downhole tool or rotary pump stator, the tool comprising a tubular housing and a jaw which pivots radially outwardly from the tool upon tool rotation to engage the casing wall for arresting tool rotation and providing significant stabilization of a rotary pump. In doing so, the tool housing moves oppositely to rest against the casing opposite the jaw. The tool housing and the downhole tool are thereby restrained and stabilized by the casing wall. The tool's jaw is released and is stowed adjacent the housing by opposite tool rotation. Preferably the profile of the jaw allows it to stow closely against the housing for presenting minimal obstruction. More preferably, the jaw is formed independent of the housing and the bore supports differential pressure so that the tool can be installed above a rotary pump or as a part of an extended tailpiece.

Title: Expanseur pour chaine stereophonique
Inventor: SIBBALD ALASTAIR
IPC: H04S1/00
Filed: 1997-11-03
Abstract: L'invention concerne un expanseur pour chaîne stéréophonique qui reproduit une image sonore réaliste en trois dimensions. Les systèmes antérieurs présentaient l'inconvénient que la création de sources sonores virtuelles ou d'enceintes acoustiques provoquait une modification tonale. Les tentatives pour corriger la modification tonale compromettaient la précision de la source sonore virtuelle. La présente invention résoud les problèmes rencontrés par les systèmes antérieurs en couplant des signaux modifiés et des signaux non modifiés. Ainsi, si l'on ne modifie pas une fonction de transfert relative à la tête pour un signal et si l'on égalise ladite fonction de transfert pour l'autre signal, on obtient une réponse de fréquence aplatie sans modification tonale mais avec une grande précision spatiale. Les signaux de sortie résultants peuvent être utilisés pour générer des signaux binauriculaires ou pour alimenter des sélecteurs diaphoniques.

Patent CA-2291021-A1 (CA)
Inventor: SHIRAISHI KENICHI
IPC: H04L27/22
Filed: 1998-06-15
Abstract: An absolute phasing circuit having a simplified phase rotating means constituting a remapper. The phase rotation angle of a receiving phase for the signal point arrangement on the transmitting side is detected, and a phase rotation signal RT (3) based on the detected phase rotation angle is outputted from a frame synchronization circuit (2). Phases of baseband demodulated signals I and Q through a demodulator circuit (1) are rotated by 45° through a ROM  (3) constituting the remapper. A logic conversion circuit (4), receiving the baseband demodulated signals I and Q  through the demodulator circuit (1) and phase rotated baseband demodulated signals i and q from the ROM (3), performs inversion of code and exchange of the baseband demodulated signals selectively and delivers a baseband demodulated signal matched with the signal point arrangement on the transmitting side. The circuity is simplified because the ROM (3) is simply required to rotate the phase of the baseband demodulated signals I and Q  through the demodulator circuit (1) by, for example, 45°.
