Patent CA-2143133-A1 (CA)
Title: Tire and vehicle system utilizing asymmetric support member molded to outer sidewall
Inventor: WEBER MICHAEL J
IPC: B60C15/024
Filed: 1995-02-22
Abstract: Improved tires designed for use in an improved tire/vehicle system having two pneumatic front tires and two pneumatic rear tires are especially effective when utilized on vehicles with a suspension system having limited camber, as in a live axle suspension system.  The tires include a support member which is molded to the inboard sidewall of one or more tires in the tire/vehicle system.  The inboard sidewall of a tire provides improved lateral stiffness in the tire, for cornering, and functions similar to cambering in tire/vehicle systems where cambering is not possible or where camber adjustment is limited.
Patent CA-2143557-A1 (CA)
Title: Automatic closure for toilet seat
Inventor: LAWRENCE JAMES C
IPC: A47K13/10
Filed: 1995-02-28
Abstract: An improved toilet seat closure is described employing weight-driven cords or cables for pivoting forward and lowering a toilet seat and its lid without a loud noise upon flushing of the toilet. The seat and mechanism for achieving the automatic closing can be easily retrofitted to existing toilets without any unsightly or major modification of the toilet or tank. The mechanism employs a flexible cable or cord which runs through a tubular sleeve and extends under and behind the tank and over the rear lip of the tank so as to be substantially out of sight to the users. The cord or cable is connected to a weight in the tank (which weight has a specific gravity slightly higher than 1 ) so that on flushing the weight draws down the cord or cable a short distance. The cord also runs over a fixed pulley and runs free to the end of a pivoting arm extension from the seat member. The end points of arc of the end of the pivoting arm are so related to the fixed point that the falling weight causes the cable to initially pivot the arm and thus the seat member from its raised position forward to past its forward tipping or falling point. The seat thereby then pivots by gravity downward but is restrained and slowed by the cable and weight system as it approaches its down or closed position.
Patent CA-2147300-A1 (CA)
Title: Downhole signal conveying system
Inventor: OWENS STEVEN C
IPC: E21B47/00
Filed: 1995-04-19
Abstract: Actuation of downhole tools is accomplished by inducing motion in the wireline. The downhole tool monitors such motion for predetermined patterns. Detection of a predetermined pattern actuates performance of a desired function. The pattern selected is sufficiently unique to avoid random or premature actuation. The tool may thus be actuated using ordinary nonconducting cable. In like fashion the tool can transmit stored information to the surface by a mechanical means such the resonant frequency of a mechanical signal in the cable.

Abstract: Pour démoduler des signaux porteurs (AS) modulés, acheminés à un appareil de télécommunication sans fil, on utilise un comparateur de données (1212) pour la transmission sans fil d'information, notamment pour la transmission d'informations spécifique de la norme DECT, à une entrée (E2) duquel est conduit un signal de référence (RS) produit par intégration du signal porteur (AS), afin de démoduler le signal porteur (AS). Comme selon l'accord de transmission DECT, outre la démodulation, il faut également reconnaître deux valeurs binaires identiques d'un mot de synchronisation (S-BW), un seuil de décision (ES) du signal de référence (RS) est modifié par une valeur d'erreur (dES). Un système de compensation (16, 19, 142) supplémentaire est de ce fait prévu dans l'appareil de télécommunication sans fil, pour compenser cette valeur d'erreur (dES).

Patent CA-2152918-A1 (CA)
Inventor: SCHULZE KLAUS
IPC: F16K17/30
Filed: 1993-12-24
Abstract: The invention takes as its basis the problem of creating a safety sealing device for gas pipes by which the bearing of the valve body should be frictionless, require no maintenance and which causes only minimal flow resistance. Further the safety sealing device should not require outward sealing connections. It should be easy to install and able to be fitted into existing gas piping or fittings without having to change them.    The problem is solved in that with safety sealing devices with a valve body (6) which can be pressed against a valve seat (1), whereby the valve body (6) is supported so that it is movable in the axial direction of the valve seat (1) is against the force of a locking spring (8), the valve body is conducted only through a spring and is otherwise freely movable without additional support points.       The invention concerns a safety sealing device for closing gas conduits in cases of damage, e.g. pipe bursts or hose ruptures, in order to prevent an uncontrolled leakage of gas and thereby a dangerous situation.
