Patent CA-2216400-A1 (CA)
Inventor: TURINA DALIBOR
IPC: H04W84/08
Filed: 1996-03-07
Abstract: La présente invention porte sur un procédé concernant un système de communication radio, agencé en vue de la transmission de données en paquets selon un protocole ALOHA de message synchronisé avec réservation. Des stations mobiles sont agencées au sein du système pour envoyer des demandes d'accès à une station de base, au cours d'une phase de réservation, dans un système de radio mobile faisant appel à ce protocole. La station de base est agencée pour recevoir des demandes d'accès en provenance d'une première station mobile et pour les satisfaire par émission d'un message de réservation de canal (2) comprenant une réservation de canal (3). La station de base est, en outre, agencée pour recevoir des demandes d'accès provenant d'au moins une seconde station mobile pour laquelle il est momentanément impossible de mener à bonne fin une réservation de canal. Selon le procédé relevant de cette invention, une demande d'accès reçue, en provenance de la seconde station mobile, est confirmée lorsqu'il est impossible de mener à bonne fin la réservation de canal de manière habituelle. La confirmation est envoyée sous la forme d'une confirmation d'accès (4, 5) figurant dans le même message de réservation de canal (2) que la réservation de canal (3) concernant la première station mobile.

Patent CA-2226282-A1 (CA)
Inventor: THOMSON GARY G
IPC: E04H3/14
Filed: 1998-01-07
Abstract: The size of a walled ball-court's playing area is changed by moving a wall into and out of one side thereof (e.g., the end of an elongate court). The wall moves on wheels rolling in horizontal tracks inset into the floor of the court. The movable wall is mounted on one end of a frame extending outwards from the ball-court, and the weight of the wall is balanced with counterweights so that the wall does not tip when moved. A mechanical drive, which may be manually powered by a single operator, applies horizontal forces to the wall in order to move it back and forth along the tracks. In a preferred embodiment, two sets of wheels, spaced out along the movable wall, are used. In this configuration the spacing between the two sets of wheels is adjustable to allow an installer to select an optimal spacing. Additional safety is provided in a preferred embodiment by providing a safety dog fixedly attached to the frame, extending into the track, and engaging the side of the track whenever the wall tilts forward toward an unstable and unsafe attitude.

Patent CA-2230466-A1 (CA)
Inventor: SUZUKI SHIGERU
IPC: B60H1/08
Filed: 1998-02-25
Abstract: A heater containing viscous fluid, which is sheared to generate heat.  The heater is provided with an electromagnetic solenoid that includes a case, a solenoid coil housed in the case, and a core extending through the case.  The heater further has a heating chamber and a sub-oil chamber.  Viscous fluid is moved between the heating chamber and the sub-oil chamber through a communication bore.  The core extends toward the communication bore.  A coil spring urges the core toward the communication bore. Excitation of the electromagnetic solenoid moves the core away from the communication bore.  The core opens and closes the communication bore and pumps the viscous fluid into the communication bore when the solenoid is cycled on and off. As a result, the heat output is accelerated.

Patent CA-2272493-A1 (CA)
Inventor: SUNDBERG HENRIC
IPC: C05F17/02
Filed: 1999-05-20
Abstract: A kitchen waste composter for composting vegetable matter comprises an outer drum having an axis for rotation which is disposed horizontally for rotation inside an outer housing. The outer drum and the housing have respective waste inlet means which are in communication with each other for receiving waste so that waste which is introduced into the housing is received inside the outer drum.  An inner drum having an axis for rotation which is disposed horizontally for rotation of the inner drum is disposed inside the outer drum. Waste outlet means formed in the inner drum is adapted to discharge decomposing waste through an open end wall of the outer drum. The configuration of the outer drum with the inner drum disposed inside, allows for a two-stage decomposition of waste matter, thereby maximizing the capacity of the composter while occupying a minimum of space which is customarily at a premium in the kitchen environment.
