Patent CA-2242475-A1 (CA)
Inventor: MARKLE EVAN
IPC: A47K13/10
Filed: 1998-07-08
Abstract: Apparatus is provided for manipulating a cover or lid between horizontal and upright positions. A foot-actuated device is connected by a first cable to a lift mechanism positioned about the lid's pivot. The first cable lies over the profile of an oblong cam in the lift mechanism. Pulling the first cable rotates the cam for rotating the lid. The cam's profile initially producing a large turning moment which compensates for the initially difficult lift and then smoothly decreases the turning moment to compensate for the decreasing force needed as the lid approaches the upright position. In the context of a toilet seat lid, it is convenient to incorporate an automatic lowering device. In upright position, a latch in the cam engages a trigger. The seat is spring-urged to close, restrained only by the latch and trigger. A  second cable is float-actuated to disengage the trigger from the latch when the tank begins to refill after being flushed. Preferably, the foot-actuated device is a double hinge located between a base and a semicircular pedal. Depression of the pedal causes two points of the hinge to retreat, pulling the first cable and actuating the cam's rotation and lifting of the lid.

Title: Compact five ring stuffing box packing assembly
Inventor: HARRELSON ALBERT L III
IPC: F16J15/20
Filed: 1997-03-20
Abstract: The compact five ring stuffing box packing assembly (56) includes high density metal inserted braided end rings (64, 66) of graphite which have each been die formed to have angled facing surfaces. Three low density graphite preform rings (58) having angled facing surfaces are contained between the high density braided end rings (64, 66).

Patent CA-2255375-A1 (CA)
Inventor: ROUSSEAU VICTOR
IPC: A01K5/00
Filed: 1998-12-09
Abstract: The cattle feed mixer comprises a self-standing container having a cylindrical inner chamber in which is journaled a coaxial shaft rotatably carrying a number of radially extending paddles. An upper opening mouth allows hay and other cattle feed elements to be poured into the inner chamber, where the paddles are rotated to mix these elements together. Sector portions of a number of circular saw blades project into the inner chamber through slits made in the bottom of its inner wall, and rotate at high velocity to shear the hay carried thereagainst by the paddles. Once the mixing and cutting operations are completed, a discharge door is opened to allow the paddles to scoop the now homogeneous cattle feed out through a discharge opening, to be dispensed in suitable receptacles. The container has a collecting trough located under the slits of the saw blades, which is connected via an upwardly-extending sleeve to the inner chamber. Augers in the trough and in the sleeve allow particulate feed elements which have seeped through the blade slits, to be reintegrated into the inner chamber.

Title: Guide wire dispenser apparatus and method
Inventor: PECOR ROBERT
IPC: A61B5/00
Filed: 1997-05-15
Abstract: A storage and dispensing apparatus for a springy guide wire used in medical procedures includes a coiled tubular portion defined by elongate tubing with a bore for receiving the guide wire.      A ring section includes a tangential portion of the tubing defining an open end from which the guide wire may be dispensed.      Adjacent to the tangential portion, the tubing defines a pair of spaced apart openings from which the guide wire respectively exits and reenters the tubing. Intermediate the pair of openings the tubing defines a curved external surface across which the guide wire runs externally of the tubing and is manually accessible for advancing and retracting movements impelled by a user's thumb, for example. The guide wire defines a pair of gentle S-shaped bends adjacent to the ends of the externally-exposed curved section, which bends cause the guide wire to engage sufficiently with the storage and dispensing apparatus to resist self-ejection.

Abstract: A system is disclosed for facilitating a secure method of payment for a commercial transaction which took place in a secure or unsecured environment. The system includes a financial persona server having a file stored therein which is configured to store information related to a user of the system. The information includes a choice of payment options. The system also includes a payment server selectively connectable to the financial persona server and operable to request one of the payment choices from the financial persona server to pay for the commercial transaction. Also disclosed is a method for enabling a purchaser to select a method of payment, and authorize a commercial transaction, between the purchaser and a merchant. The method includes providing the purchaser with an account on a financial persona server, an account number representing the account and a secure connection to the financial persona server. It includes enabling the purchaser to input, over the secure connection, two or more payment options into the account. The method also includes receiving, at a payment server, a message from the merchant, which identifies the transaction and the account number. The payment server communicates the message to the financial persona server and in response, the financial persona server requests an authorization and a payment choice from the purchaser. If the financial persona server receives the authorization and the payment choice from the purchaser, the financial persona server communicates the payment choice to the payment server over a secure link. The payment server receives the payment choice and forwards it over a secure link to a financial institution for further authorization. If the payment server receives authorization from the financial institution the payment server communicates an authorization code to the merchant.

Title: Asynchronous transfer mode switch and method of controlling cell priority
Inventor: SAITO TSUNEHISA
IPC: H04L47/80
Filed: 1999-09-08
Abstract: In an ATM switch, an internal cell converting portion converts cells input from a transmission line to internal cells with added priority control information set in advance within the switch. The ATM switching portion routes the above-mentioned internal cell and transmits it to a priority control portion 40. A priority control portion is established for each class represented by the priority control of information and comprises a class unit buffer. The priority control portion executes priority control for the internal cell through the pertinent class unit buffer based on the priority control information added to the cell. The internal cell converting portion converts the internal cell, after priority control, to a usual ATM cell without the priority control information and outputs the ATM cell to a transmission line.
