Title: Center wind assist driving wheel mechanism
Inventor: KREMAR DJURO
IPC: B65H19/22
Filed: 1995-05-25
Abstract: A center wind assist mechanism for use in a web winding device for winding a substantially continuous web onto a reel bar. The winding device includes a driving drum that maintains a first nip engagement with the reel bar to rotate the reel bar and transfer the web passing over a surface of the driving drum onto the reel bar. The web winding device further includes a transfer mechanism for moving the reel bar from a primary winding position to a secondary winding position while maintaining the reel bar in nip driving engagement with the driving drum. The web winding device is characterized by a center wind assist mechanism for applying a driving torque to the reel bar as the reel bar moves from the primary winding position to the secondary winding position. The center assist winding mechanism includes a drive assist support arm pivotally mounted to the transfer mechanism to move therewith and pivot relative thereto. A driving wheel is rotatably connected to the drive assist support arm. A drive mechanism and transmission mechanism cooperate to rotatably drive the driving wheel. A tensioning mechanism is connected to the transfer mechanism to maintain the driving wheel in driving and torque transfer relation with a peripheral surface portion of the reel bar. The center assist drive mechanism insures a more distributed nip pressure being applied across the web passing between the reel bar and winding drum during this initial phase of winding.

Title: Anti-fraud credit card dispatch system
Inventor: SEILER DIETER G
IPC: G07F7/10
Filed: 1993-12-24
Abstract: PCT No. PCT/CA93/00560 Sec. 371 Date Jun. 22, 1995 Sec. 102(e) Date Jun. 22, 1995 PCT Filed Dec. 24, 1993 PCT Pub. No. WO94/16415 PCT Pub. Date Jul. 21, 1994An anti-fraud system for the dispatch of credit cards to customers, rendering the new card useless to anyone other than the intended customer. Validation of the new card is accomplished at any retail outlet by means of a timed sequence at the transaction processing computer which ensures that any first-time sales authorization request under the new card is followed immediately within a prescribed time interval by a reading of the old credit card number and expiry date. The system also operates if the old card is tendered first at a sales outlet after the new card has been issued. This unique sequence of events will then automatically invalidate the old card, validate the new card, and indicate to the card issuing company that the customer has acknowledged receipt of their new card. Since both the old, expiring card, and the new card are required in order to validate the new card, an unauthorized party in illegal possession of the new card only, cannot use it.

Title: In-line incrementally adjustable electronic expansion valve
Inventor: EBER DAVID H
IPC: F16K31/02
Filed: 1995-08-15
Abstract: A variable flow rate expansion valve designed for in-line installation in a fluid conveying conduit such as between the high pressure condenser and lower pressure evaporator of a refrigeration system includes an integrally defined restrictor disc and a closure disc for controlling the flow of fluid through the valve.  The restrictor disc has a first set of flow apertures and the closure disc a second set of flow apertures.  The closure disc is rotatably coupled to the restrictor device in a plane parallel to the plane of the restrictor disc and perpendicular to refrigerant flow.  A stepper motor is coupled to the closure disc through a linear actuator.  Movement of the linear actuator causes the closure disc to rotate relative to the restrictor disc such that the flow apertures of the closure disc are selectively brought into and out of registry with the apertures of the restrictor disc.
