Patent CA-2220535-A1 (CA)
Title: Steering control system for tracked vehicle
Inventor: STRAETKER JOHN GEORGE
IPC: B62D11/18
Filed: 1997-12-01
Abstract: A steering control system for a tracked vehicle includes a spring centered steering wheel which is rotatable in both directions to endstops. A steering control unit executes a transitional counter-rotation (TCR) mode algorithm which disables steering or counter-rotation when the gear lever moves from park to neutral or from park to neutral to gear while the clutch is disengaged. Steering function can be re-enabled by turning the steering wheel to its centered position and then turning the steering wheel in either direction away from its centered position, or by turning steering wheel towards one of its endstop positions (without centering the steering wheel). If steering or counter-rotating is enabled the second way, then during a transition period the turning rate as a function of the position of the steering wheel will be less than that of normal operation. If the steering wheel is then held at the endstop position, the control system will automatically and gradually increase the rate of turning (by increasing an electronic steering gain value) until full normal turning rate capability is attained.

Title: Hydroponic cultivation receptacle
Inventor: SCHAERER EMIL A
IPC: A01G31/02
Filed: 1998-01-27
Abstract: A hydroponic cultivation receptacle comprising a tray 22 having a board 22a to place seeds of small vegetables like sprouts has plural drainage holes 23 on the board 22a and upper rims of said drainage holes 23 to form protrusion 24 so as to retain a little amount of water to dip lower part of the seeds placed on the board 22a. Accordingly, water remained to the height of protrusion 24 retains enough water to keep lower part of the seeds by surface tension while most water provided inside tray 22 drained from the drainage holes 23. Protrusion 24 prevents the seeds from moving from the place they are uniformly placed and the problem of moving of the seeds when water is poured is also solved.

Abstract: L'invention concerne un nouveau système d'encapsidation de rétrovirale dans lequel les plasmides d'encapsidation rétrovirale et les transcrits vectoriels se prêtant à l'encapsidation sont obtenus à partir de plasmides à forte expression après la transfection stable ou transitoire de cellules mammaliennes. Il en résulte dans ces cellules transfectées des titres élevés pour les rétrovirus recombinés, d'où la possibilité d'une transduction ultérieure de cellules cibles mammaliennes par coculture ou par infection par des surnageants. Les procédés décrits font intervenir les nouveaux vecteurs et plasmides d'encapsidation rétrovirale pour la transduction de cellules humaines primaires, y compris les lymphocytes T et les cellules souches hématopoïétiques humaines, par l'intermédiaire de gènes étrangers suite à une coculture ou à une infection par des surnageants très efficaces. Le système est utile pour la production rapide de surnageants viraux à titre élevé et la transduction à haute efficacité de cellules réfractaires à la transduction effectuée par des moyens classiques.

Title: Control of handoff in cdma cellular systems
Inventor: MEIER STEVEN KENT
IPC: H04B7/26
Filed: 1999-04-20
Abstract: This invention relates to an arrangement for efficiently providing an up to date neighbor list for base stations serving a wireless cellular telecommunications call. The neighbor list is required by a mobile station measuring signal strengths of signals for surrounding base stations in order to locate base stations from which the mobile station can receive strong signals. When one base station receives a revised neighbor list from another base station, it receives a revised neighbor list from another base station, it receives a time stamp identifying when that revised neighbor list was created. Thereafter, when a request for data from a base station is transmitted, it is transmitted with that time stamp; no neighbor list is returned if the time stamp matches the time stamp stored with the neighbor list of the base station receiving the request.

Patent CA-2272353-A1 (CA)
Inventor: SAINTS KEITH W
IPC: H04B7/26
Filed: 1997-11-13
Abstract: The present invention provides a method and apparatus for providing improved quality or power control by recognizing the delays inherent in a closed-loop communication system. The mobile station (12) or receiver properly adjusts its forward link quality or power level thresholds or measurements with which it compares incoming frames or portions thereof to reflect the level it anticipates receiving (after the delay). For example, the mobile station (12) can recognize that at a given measurement time, two outstanding messages have not been executed by the transmitter (where each message indicates a corresponding increase of 1 dB). As a result, the mobile station (12) can adjust its measurement threshold down by 2 dB to more closely correspond to future power adjustments. If the currently received frame or portion thereof is still below the readjusted threshold, then the mobile station (12) sends out a new message to request a further increase in the forward link channel.
Patent CA-2272884-A1 (CA)
Title: Manufacture of reconstituted wood products
Inventor: COLEMAN JOHN DOUGLAS
IPC: B27N3/08
Filed: 1997-11-25
Abstract: A method and apparatus are disclosed for making a reconsolidated or reconstituted wood product from a charge of wood components and binder using steam injection pressing to consolidate and bind the charge into a mat in which the wood components are bound to each other to form the wood product. The charge is compressed into the mat by operation of at least the one pressing member in the form of a heated movable platen. The method and apparatus are characterized by the pressure being applied to the charge or mat from the steam injection pressing being independent of the compressing force applied to the charge or mat by the pressing member. The invention is particularly adapted to form beams of relatively large cross section, such as for example in excess of 30 mm, preferably larger than 40 mm.
