Patent CA-2215361-A1 (CA)
Inventor: REGNAULT JOHN CHRISTOPHER
IPC: H04M15/00
Filed: 1996-03-29
Abstract: A method of, and a system for, detecting possible fraudulent use of a telecommunications network. Call event records, both call initiation and call completion records, are examined. A call record has a number of key fields, e.g. called number, calling number, calling card number, and for each field in turn the key is used to access a database containing an associated set of profiles. Each profile contains an algorithm defining a measurement process to be performed on the call data, e.g. determine the call duration. The respective process results are added to a respective set of stores associated with each profile, and an alarm response is generated when a threshold of a store is reached. An additional process for e.g. a call duration of e.g.  called number card calling number key fields, convert the process results to penalty points which are added to a penalty points store associated with the calling card number key of the call event record under examination. Each response is recorded in a history file for that key.

Abstract: A shuttle conveyor for a work station disposed between two conveyor sections is provided with a pair of shuttles which overlap the centerline of the work station to receive a work piece from an input conveyor and deposit it to a work station during the period of time when a second conveyor is unloading the work station and depositing the work piece on a continuing conveyor section.  The dual shuttle arrangement eliminates the need for a single shuttle to perform all of the loading and unloading steps and further eliminates the need for empty return adding to cycle time.

Abstract: In order to call a casting mould with a molten metal, the latter is caused to flow into through an annular chamber into the shaped cavity of a casting mould, such annular chamber discharging along the entire external circumference of the shaped cavity into the latter. The inflow of molten metal into the annular chamber is interrupted by means of a piston, which, being borne inside the annular chamber, is capable of sliding therein. The molten metal is caused to flow across a large flow cross-section, which shortens the filling time even with reduced flow velocity.

Abstract: A spray nozzle actuator has a fitment for placement on the ring fitting of a spray can, an hinge or resilient portion, a nozzle pressing portion, and an handle portion extending forwardly of, and along the can. The handle is shaped to avoid obstruction of the spray nozzle, such as by having a large aperture through which a cone of spray may flow with little or no impingement. Using one actuator an operator can hold the spray can in the palm of one hand and reach forward with his or her fingers to grasp the handle. A generally rearward pull on the handle causes the spray can nozzle to move, releasing the spray. In another actuator an operator can reach forward with his or her fingers to grasp the can, and can squeeze the handle toward the can with the palm or a substantial portion of the thumb, using the major muscles of the hand.

Title: Method and system fo facilitate motion analysis
Inventor: BALL KEVIN ARTHUR
IPC: A61B5/11
Filed: 1998-12-02
Abstract: A method and system to facilitate motion analysis of a first bone or segment with respect to a second bone or segment connected to the first bone or segment by a joint is disclosed.      The subject is initially asked to perform a simple initializing movement, such as a repeatable planar movement, and representative of the joint's primary movement pattern, such as flexion. The temporal positional information of markers attached to the first segment and the second segment are analyzed during the initializing movement. From the temporal positional information during the initializing movement, a helical angle and axis, as well as an offset vector, can be determined. Corrective matrices are then generated to align the temporary origin with a corrected origin and local frame of reference based on the helical angle and axis and the offset vector. Analysis of the kinematic movement of the joint with respect to the corrected origin and local frame of reference provides improved analysis of the kinematic data for the joint.

IPC: H01H3/30
Filed: 1999-05-06
Abstract: The large close spring in the operating mechanism of electrical switching apparatus is charged by a charging mechanism which includes a charging cam mounted on a cam shaft and rotated by a ratchet wheel. An elongated handle is mounted for rotation about a pivot axis offset laterally from the cam shaft. A drive link which successively engages the teeth on the ratchet wheel is pivotally connected to the handle at a point closer to the handle pivot axis than the radius of the ratchet wheel to increase the mechanical advantage of the handle. A common spring biases the drive link and a stop dog against the ratchet wheel. A turned pin on the drive link is used to engage the ratchet teeth which have an arcuate profile including a radius at the root configured to be engaged by the turned pin. A similar drive link with a turned pin to engage the ratchet teeth is reciprocated by an electric motor. A handle decoupling cam and a motor decoupling cam left the respective drive links out of engagement with the ratchet wheel when the close spring becomes fully charged. A lifting pin and/or a lateral projection on the handle drive link disengage the handle from the ratchet wheel as the handle is stowed.
