Patent CA-2135760-A1 (CA)
Title: Shaping metals
Inventor: LINZELL GEOFFREY R
IPC: B24B1/00
Filed: 1993-05-27
Abstract: A common way of shaping a metal workpiece by the removal of material therefrom involves rubbing contact, as experienced in a conventional wedge-shaped metal or ceramic cutting tool or in abrasive rubbing using grinding wheels. In conventional cutting and abrading it is commonplace to introduce at the cutter/workpiece interface a material that principally acts as a coolant and as a chip remover but which normally has lubricating properties to minimise rubbing friction. The method of the present invention, in contrast, depends for its function on deliberately causing very high levels of friction between the tool and workpiece; it proposes a method of shaping metal in which the surface of the workpiece is "rubbed" by a tool in a friction-inducing manner and in the presence of an anti-lubrication (friction enhancing) agent in a quantity and in a form such that actual friction enhancement occurs. Such an anti-lubricant allows, under some conditions, any part of the tool in rubbing contact with the workpiece surface momentarily to heat and soften the surface, whereupon, due to the system's momentum (as the rubbing action continues), the further friction caused by the tool shears off the softened surface material under and forward of the contact with the tool.
Patent CA-2135939-A1 (CA)
Title: Turnstile
Inventor: MCGUIRE JOHN D
IPC: E06B11/08
Filed: 1994-11-16
Abstract: A turnstile is disclosed which is easily adapted to operate in either a clockwise or counterclockwise direction of rotation and which does not permit reverse rotation during operation. Resistance to rotation in the reverse direction is achieved by means of a drag shoe mechanism. As a rotor mechanism rotates about a corresponding stator mechanism it trails a drag shoe by a rigid connecting rod, or drag arm, across a bearing surface. The drag arm is disposed at a non-perpendicular angle. In reverse motion the angularly inclined drag arm forces the drag shoe to jam into the bearing surface and thereby act as a brake. The turnstile is provided with a quick release wrench, an safety release bolt which protrudes beyond the housing of the turnstile mechanism, and emergency release instructions labels clearly visible on the top and pillar of the turnstile. Should a child, or other person,become trapped in the turnstile one may easily and quickly release the turnstileby inserting the wrench in the safety release bolt and loosening the mechanism. When loosened the mechanism, and hence the turnstile, swings freely in either direction.

Abstract: Un procédé qui permet d'enduire d'uréthane des tuyaux de différentes matières afin de les isoler contre la chaleur ou le froid. C'est une structure métallique sur roues qui se déplace tranquillement pendant qu'un jet d'uréthane est projeté à l'intérieur d'un moule cylindrique fixé à la structure, afin de recouvrir un tuyau qui est placé au centre de ce moule. Deux (2) éléments sont essentiels dans ce procédé: un fusil qui permet l'injection de l'uréthane et une structure qui sert d'appuie au tuyau et permet le déplacement d'un moule cylindrique autour du tuyau. La structure rectangulaire sur roues comprend un moteur qui lui permet de se déplacer d'elle-même et des supports surmontés de billes sur lesquelles le tuyau pourra s'appuyer et glisser. Le moule est fixé à une certaine hauteur de la structure permettant ainsi à un individu de monter sur le plancher de la structure et à l'aide du fusil, de projeter l'uréthane dans le moule. Pour que l'uréthane n'adhère pas au moule, une membrane de plastique, un coupe-vapeur aluminisé ou un coupe-vapeur de vinyle sera utilisé.

A support frame has a forward end attached to the snow working implement and a rearward end pivotally connected to the intermediate frame for rotation about a horizontal axis.  A latching mechanism on said intermediate support frame for positioning a latch member rearwardly of the transverse latch bar means.  A lift mechanism on the intermediate support frame pivots the support frame about the horizontal axis and lifts the support frame and working implement off the ground such that the weight thereof is borne by the reason bearing surfaces and the pair of spaced socket means.  A friction slide plate maintains the angular relationship between the intermediate frame and the support frame when the intermediate support frame is not coupled to the VMA frame.

Title: Wood pellitizer apparatus and method
Inventor: FISHER GERALD M
IPC: B27C7/00
Filed: 1995-01-19
Abstract: A peripheral drive log lathe having no sliding surfaces susceptible to wear in either the log pinching apparatus or in the knife assembly. All loads are transfered to the frame members through rotary bearings. The knife assembly is self aligning to the thickness W of the veneer cut by the fixed distance W between the noseroll and the knife edge. The idler rolls are mounted on a carriage which can only move in parallel planes as determined by a three point translation scheme. A trio of ball screws and nuts provide synchronized drive to the three points. A rounding actuator controls the knife assembly until the log is rounded at which time the rounding actuator is de-energized and the becomes self aligning.

Title: Load cell with modular calibration components
Inventor: GRIMM STEVEN R
IPC: G01G3/14
Filed: 1995-02-01
Abstract: A digital load cell includes an EEPROM that is permanently attached to the counterforce along with a temperature sensor and a plurality of strain gages. The strain gages are mounted on the counterforce in the electrical configuration of a full wheatstone bridge. The EEPROM and bridge are connected to a flexible circuit that is detachably connectable in electrical communication with circuits including a processor and an analog-to-digital converter, which can be mounted permanently on a local circuit board physically separated from the EEPROM. The local circuit board operates in a manner so that the EEPROM can be programmed to store the calibration/correction factors that are to be applied by the processor to the digital weight signals from the analog-to-digital converter.      The local circuit board is associated with, and alternatively can be removably attachable to, the counterforce.

Title: Atm transmission system
Inventor: WAKE YASUHIRO
IPC: F16C29/04
Filed: 1995-11-23
Abstract: An LD-CELP coder 211 codes an input signal supplied through a telephone line based on the low-delay code-excited linear prediction.  A speech detector 212 detects voice/no-voice of the input signal.  A FAX terminal input detector 213 detects a FAX signal.  A multiplexer 214 multiplexes the coded data and the voice/no-voice data through bit steal of one bit per frame from the code.  In a CLAD (cell assembling and disassembling) unit 300, a speech data frame is detected, and also the voice/no-voice information that has been multiplexed in the coded data is detected.  If the voice/no-voice information indicates voice, the coded data is converted to cell data to be sent out to a transmission line.          Concurrently with the operation of the coder, FAX terminal input data is all converted to cell data and sent out to the transmission line independently of the voice/no-voice information.

Title: Vehicle tracking system
Inventor: HAAGENSTAD JEFFREY D
IPC: G08G1/087
Filed: 1994-05-17
Abstract: An embedded system controller-based vehicle tracking system using vehicle positioning. An embedded system controller controls a traffic intersection using an optical system. The embedded system controller receives a vehicle location and a vehicle schedule. The embedded system controller calculates whether the vehicle is on time and reports the on-time status to the driver interface. The driver may request that the system report a panic or emergency situation to the dispatch center through an external data communications network. The external data communications network may also send vehicle status, such as vehicle position and vehicle condition. A transit company using the system may provide vehicles equipped with the vehicle tracking system with schedules on a daily basis, using a portable data transfer device. The embedded system controller also communicates to the vehicle data network for the communication of vehicle position. A global positioning system receiver may be used to provide the position of the vehicle to the embedded system controller.
