Patent CA-2189274-A1 (CA)
Title: Heavyweight lock
Inventor: FAVEL RICHARD VICTOR
IPC: E05G1/02
Filed: 1996-10-31
Abstract: The  "HEAVYWEIGHT   LOCK"  is a theft  preventive   measure designed   to  protect   computer   towers.   It  acomplishes   this  by clamping   the  tower  in a 4 inch  wide  band  of 3/8  inch  steel placed  midway  along  the tower's  length.  This  band  is a U shape and  is screwed  into  a multiple   and  interlocking   stack  of one inch  thick  iron  weights. (L=18-20")     The  top  weight  has  a 1/2 stopper  at the front  and back  of the tower, thus   preventing   it being  slid  forward  or backward   out  of the  clamping   devise.          The  stoppers   in no way  inhibit  any  conection   or switching   on the  tower.          The fact  that  the U shaped  clamp  is holding  the tower  firmly, it cannot  be lifted  above  the  1/2  inch  stoppers.          Also  the U shaped  clamp  is secured  with  tamperproof   set screws,   preferably   of two  or three  different   types  or sizes.          Becasuse   the weights  are  interlocking   the  "HEAVYWEIGHT   LOCK" can  be made  as heavy  as is needed.
Patent CA-2189519-A1 (CA)
Inventor: PAPE JAMES D
IPC: E04B1/86
Filed: 1996-11-04
Abstract: This invention describes two products both with a plain, nonperforated surface visual consisting of a fiberboard substrate with or without a laminated porous nonwoven scrim and then a finished painted surface.  The finish painted surface decorates or finishes the board, but most important, must remain acoustically transparent to retain the sound absorption properties of the fiberboard prior to painting.  The fiberboard substrate is made to be porous or modified with hole perforations to cause it to be a good sound absorber.  If the fiberboard substrate is sufficiently porous without hole perforations, then the sprayable, high solids, porous paint can be directly applied.  If hole perforations are used to improve the sound absorption properties of the board substrate, then a porous, nonwoven scrim is attached and painted using the same high solids porous paint.  This painted scrim must be sufficiently optically opaque to hide the hole punched board, yet sufficiently open to render it acoustically transparent. The inventions also include the paint coating alone or the paint/scrim coating alone.

Abstract: A variable ratio drive pulley of the type employed in snowmobiles to transmit a drive from the snowmobile engine to a variable ratio belt drive transmission has a fixed flange and an opposed movable flange which cooperate to drive the belt.  The drive pulley is coupled to rotate with the engine crankshaft and the movable flange incorporates a centrifugal means that operates to advance it towards the fixed flange, with a force that increases with speed of rotation, to grip the transmission belt between the flanges and apply a driving torque thereto, this torque being applied by both the flanges.  To reduce the effects of engine induced vibrations on the centrifugal means and on the movable flange, a damping structure is incorporated in the torque path between the engine crankshaft and the centrifugal means and movable flange.  The damping structure comprises a hexagonal rubber ring that is positioned between a driving head and the hub of the drive pulley to absorb vibrations which would otherwise be transmitted between these.

Title: Automatic sample testing machine
Inventor: FLENDER GREGG
IPC: G01N35/10
Filed: 1997-02-12
Abstract: An automatic sample testing machine for testing samples stored in test cards. The machine has a test sample positioning system for moving a tray containing a plurality of test sample cards and fluid receptacles among various stations in the machine. The machine has a diluting station for adding a predetermined quantity of diluent to the receptacles as needed. A pipetting station transfers fluid from one receptacle to another. A vacuum station is provided having a vacuum chamber moveable relative to the tray between upper and lower positions. The chamber cooperates with the tray to make a sealing engagement with the top surface of the tray when it is lowered to the lower position. A vacuum generator supplies vacuum to the chamber. When the vacuum is released from the chamber, the fluid samples are loaded into the cards from the receptacles. The test sample positioning system moves the tray to a cutting and sealing station and then to an incubation station and loads the cards one at a time into a carousel within the incubation station. A test card transport station transports the test cards from the incubation station to an optical reading station, where optical measurements (e.g. transmittance and/or fluorescence optical testing) is conducted on the wells of the card. When the card has been read, it is either moved back to the incubation station for additional incubation and reading or transferred to a stacking card disposal system when the reading is complete.
