Patent CA-2147651-A1 (CA)
Title: Selectively actuatable lighter
Inventor: MCDONOUGH JAMES M
IPC: F23Q2/28
Filed: 1993-10-22
Abstract: A selectively actuatable lighter device (10) is disclosed which includes a body defining reservoir (12) for containing a combustible gaseous medium such as butane, and having a valve (20) arranged to be selectively actuated between a normal-ly closed position and an open position which permits the exit of the gaseous medium. Such lighter (10) can selectively pro-duce sparks at a location (19, 22) proximate to the gaseous me-dium exit to ignite the gaseous medium. Such lighter device (10) embodies a resiliently releasable valve actuator (14) which nor-mally prevents actuation of the valve (22). The valve actuator (14) includes an interfering portion (14A) which is selectively movable to a position (Fig.11) out of interference with an inter-fering portion (12A) of the lighter body, so that the gaseous me-dium may be released and ignited by the sparks. Once the valve actuator (14) is depressed and released, it returns to its closed or latched position to prevent actuation of the valve to the open position. To "re-use" the lighter, the valve actuator (14) must again be moved to an unlatched position so that the valve (22) can be actuated for subsequent ignition of the gaseous medium.

Title: Controlled torque power steering system
Inventor: CURNOW JOHN W
IPC: B62D5/065
Filed: 1995-06-02
Abstract: A controlled torque power assist steering system for a vehicle for controlling the level of power assist provided by an hydraulic power assist steering mechanism in response to torque exerted on a steering wheel of the vehicle by a driver.          The system includes a torque sensor mounted on the steering column of the vehicle which senses the torque exerted thereon as the steering wheel is turned.   The torque sensor generates a corresponding torque signal which is applied to an electronic controller, which in turn generates a current control signal to an electronically variable orifice (EVO) actuator valve.  In a first embodiment, the value of the current control signal is based upon a predetermined response curve of input torque versus EVO drive current.   In a second embodiment, a vehicle speed signal  is also supplied to the controller and the desired response curve is varied in accordance with changes in vehicle speed.    The preferred  form of  the  controller comprises  a microcomputer-based digital controller that controls the EVO actuator valve using pulse width modulation control.

Title: Apparatus for treating spinal disorder
Inventor: RIVARD CHARLES-HILAIRE
IPC: A61B17/70
Filed: 1994-02-09
Abstract: An internal brace system (10) includes a pair of implantable rods (12,14) for mounting on either side of the spinal column S co-extensive with a portion of the spinal column to be treated. Transverse bars (16,18) rigidly connect the rods (12,14) together in spaced-apart parallel arrangement to provide a unitary internal brace stabilizing structure. Pairs of anchors in the form of cuffs (20a, 20b) are provided with one of each pair on respective transverse processes (P L, P R) of each selected vertebra (V) in the portion of the spinal column (S) to be treated. A flexible first tie member (22a,22b) extends from each anchor cuff (20a,20b) to a sleeve (24a,24b) on a respective rod (12,14) on either side of the spinal column S for retaining individual vertebra (V) in a predetermined location relative to the internal brace system (10) and against torsional forces applied through the spinal column S. A further anchor (78) is provided on the spinous process of the selected vertebra (V). Second flexible tie members (84) extend from the respective cuffs (20a,20b) on the transverse processes (P L, P R) to the anchor (78) on the spinous process (T) in order to prevent the cuffs (20a,20b) from slipping off the transverse processes (P L, P R).

Patent CA-2159647-A1 (CA)
Title: Board game
Inventor: BERTOLO ALBERT R
IPC: A63F1/00
Filed: 1995-09-27
Abstract: The Board Game consists of a uniquely designed board, 4 sets of 4 different coloured marbles, and a deck of ordinary playing cards.  The game can be played with 2, 3, or 4 players.          A player selects a set of the 4 coloured marbles.          Each player places his/her marbles in the "on-deck" position. The Dealer distributes 5 cards to each player in the first round, and 4 cards to each player in the subsequent rounds.  Thus having gone through the deck, the deal is passed on to the player on the left. In order to move a marble from the "on-deck" to the "start" position, the player must play an Ace or King.  If a player does not have an Ace or King to open, he/she forfeits their cards and places them face up in the centre of the board.          Each player follows in sequence. The marbles are advanced clockwise around the board to the "house" (finish) position in accordance with the face value of the card played. The first player (or partners) to advance all marbles from the "start" position to the "house" (finish) wins the game.

Abstract: The drug-loaded stent includes an expandable stent structural member, and a planar sheet of polymeric material attached to the outside of the expandable stent structural member. The polymeric material preferably is bioabsorbable, and loaded or coated with a therapeutic agent or drug to reduce or to prevent restenosis in the vessel being treated. The polymer material can be attached to the metal stent at one or more points, and wrapped in a coil around the stent in an unexpanded state, to uncoil and expand in diameter to substantially match the expanded diameter of the metal stent; or can be wrapped tightly around the stent structural member and attached to itself, to stretch radially when the stent structural member is expanded. In another currently preferred embodiment, a combination of a stent structural member and a polymeric film wrapping can be provided with a coating of lubricious material. The lubricious material can be polyethylene oxide, polyethylene glycol, polyethylene acetate, polyvinyl pyrrolidone, polyvinyl alcohol, polyacrylamide, hydrophilic soft segment urethanes, some natural gums, polyanhydrides or other similar hydrophilic polymers, and combinations thereof. The layer of lubricious material protects the stent from the guide or the body lumen in which the stent is inserted by providing a low friction surface over the stent.

Title: A brassica sp. gene promoter highly expressed during tapetum development
Inventor: ROBERT LAURIAN S
IPC: C12N15/82
Filed: 1996-02-06
Abstract: A Brassica sp. genomic clone containing a gene promoter, which directs expression in the tapetum, was isolated. When the promoter was fused with the GUS gene and introduced into B. napus by Agrobacterium mediated transformation, this promoter controlled GUS expression in the tapetum in transgenic B. napus plants. Expression was observed from bud length 2-3 mm, which corresponds to the uninucleate microspore stage, peaked at 4-5 mm which corresponds to the binucleate microspore stage and declined to no detectable level at the open flower stage. There was no GUS expression in other tissues such as root, stem, leaf, sepal, petal or pistil. This promoter will be useful for the temporal and spatial control of gene expression in plants.
