Patent CA-2010345-A1 (CA)
Inventor: ATALLA MARTIN M
IPC: G06Q20/40
Filed: 1990-02-19
Abstract: A method and apparatus ng electronic financial transaction processing systems used by customers of certain credit or electronic banking card-issuing institutions. The present invention involves two levels of secure interaction between the customer and the card-issuing institution. The first level of interaction involves the enrollment of a customer in the institution's electronic financial transaction processing system.  The customer either selects or is issued a personal identification number and a card encoded with a personal key.  The personal key and personal identification number are used to generate a PIN transmission number and personal verification number, which is stored in bank records. The second level of interaction involves the authorization of a customer's use of the electronic financial transaction processing system for executing an electronic transaction.  The customer enters his personal identification number and the system reads his encoded card, both of which are used generate a candidate PIN transmission number.  The candidate PIN transmission number is transmitted to a remote processing center by computer network.  The system, at the remote processing center, generates a candidate personal verification number using the transmitted candidate PIN transmission number and compares the candidate PIN transmission number for parity with a PIN transmission number stored in the institution's records.

Title: Method and apparatus for managing tasks
Inventor: NIITAKA KOJI
IPC: G06F9/46
Filed: 1990-05-28
Abstract: ABSTRACT OF THE DISCLOSURE    A method and an apparatus for scheduling tasks, which dispatches high and low priority tasks in predetermined intervals. High priority tasks are performed before low priority tasks while successively executed high priority tasks are counted up to a predetermined value. A low priority task is automatically dispatched and executed if the counted number reaches the predetermined value before all high priority tasks are completed. As a result, the method and apparatus can prevent low priority tasks from remaining without execution for long periods of time even when there are many high priority tasks to be executed.

Title: Room temperature jet printing ink and method
Inventor: KRUSE JURGEN M
IPC: C09D11/02
Filed: 1990-07-13
Abstract: An ink jet composition for printing paper, and which is a low viscosity fluid at room temperatures, comprises a sol wherein (a) the liquid medium comprises a non-aqueous solvent, preferably a glycol ether and (b) the disperse medium comprises an amount of a resin which is capable of forming a solution in the solvent at a temperature in the range 20 to 35°C and a dyestuff which is soluble in or bound to the resin at said temperature but is substantially insoluble in the solvent at said temperature; and optionally (c) a suspending agent.

Abstract: SHOPPING CART LOCKING MEANS                     ABSTRACT OF THE DISCLOSURE An infant carrier (2) for secure attachment of a shopping cart (4).  The infant carrier includes a seating section (5) for supporting the infant.  The seating section includes a bottom portion (6) and a back portion (8) disposed at an angle to the bottom portion.  Side portions (10) are located adjacent to and substantially perpendicular to the back and bottom portions.  Rear side extensions (12) are coplanar with the side portions, extending rearwardly therefrom, and include a lock (14) for securely attaching the carrier to a horizontal wire (20) of the shopping cart.  The lock is disposed on a rear surface (13) of the rear side extensions in an elongated opening (26) formed in the rear surface.  The lock includes a resilient cantilever member (28) connected by a connection end (32) at a lower end (30) of the opening.  A latch (34) is disposed remote from the lower end for retaining the horizontal wire within a recess (22) formed in the rear side extension.  To lock the horizontal wire in the recess, the infant carrier is positioned such that the latch contacts the horizontal wire. The infant carrier is pushed downwardly such that the horizontal wire exerts a force (arrow A) on the latch, pushing the resilient member into the opening.  The horizontal wire is thus received in the recess.  The resilient member is biased to its normal position such that an upper support surface (42) of the latch retains the horizontal wire within the recess.

Patent CA-2023700-A1 (CA)
IPC: G01P3/488
Filed: 1990-08-21
Abstract: A variable reluctance rotation sensor comprises a rotatable magnetic toothed wheel adjacent a fixed magnetic pickup assembly.  The pickup assembly comprises a pair of permanent magnets, each with a similar pole adjacent the wheel and separated circumferentially by the arc between a tooth and a non-adjacent slot.  A magnetic flux member with a coil joins the other poles of the magnets in series opposed relationship and extends in close proximity to the toothed wheel to establish separate flux loops for each magnet distributed along the coil.  The flux loops are spatially determined by the teeth and slots between the permanent magnets, so that they fluctuate circumferentially and generate an electrical signal in the coil with wheel rotation by variation of the flux linkages to individual turns of the coil.  The sensor thus uses spatial flux changes to produce a rotation signal at very low rotational speeds with a larger air gap than that of conventional sensors.

Title: Shower head
Inventor: BAKER BERNARD
IPC: B05B1/02
Filed: 1990-10-23
Abstract: ABSTRACT OF THE DISCLOSURE            A showerhead is disclosed, which has a water chamber closed by a plate having a series of water ports through which an equal number of valve plugs slidably fit to control water flow through the ports.  The valve plugs are held in the chamber by a radial header at one end of a displacing member which also comprises a sleeve portion that projects out of the chamber.   The header and plugs are moved by an operating member which is mounted for rotation  only  around  the  sleeve  projecting  portion. Mounted within the sleeve is a water conducting stem which has one end secured to the chamber closing plate and which is constructed to allow flow of water into the chamber. The stem is constructed to prevent reciprocation of the operating member along the central sleeve.   A pair of parallel helical grooves formed on the outer surface of the central sleeve.   Finally, follower pins are provided on the operating member, each pin projecting into one of the helical grooves.   In this manner,  as the operating member is rotated relative to the central sleeve and to the  chamber,  the  pins  ride  along  the  helical  grooves between their ends and allow the displacing member to be reciprocated linearly so as to allow the valve plugs to control water flow through the ports.
