Patent CA-2157949-A1 (CA)
Title: Method for extinguishing a fire
Inventor: MARS HANS ALBERT
IPC: A62C35/02
Filed: 1995-09-11
Abstract: When extinguishing a fire by means of an extinguishing gas, after a fire is detected, the extinguishing gas is supplied under high pressure to the area in which the fire has broken out, with simultaneous displacement of air. In order to prevent gas speeds which are too high, the extinguishing gas is fed, in a first step, into a chamber which is delimited by a porous wall and subsequently, in a second step, is fed via the porous wall to the fire to be extinguished. Preferably, the displaced air is removed at a location which is related to the ratio of the specific weights of air and extinguishing gas.

Patent CA-2167909-A1 (CA)
Title: Automotive vehicle, preferably golf caddy
Inventor: BAIL GUENTHER
IPC: A63B55/60
Filed: 1994-07-27
Abstract: An automotive golf caddy has a high frequency position finder and an ultrasonic position finder. When the caddy is placed in readiness by means of a manual transmitter, it first determines whether it receives ultrasonic signals from the manual transmitter. If that is not the case, it determines by high frequency position finding the direction of the manual transmitter and approaches the transmitter on a straight path at a relatively high speed. When the caddy enters the ultrasonic position finding range, it is automatically switched to ultrasonic position finding, follows the manual transmitter even in curves and continuously determines its distance from the transmitter. When a predetermined minimum distance is reached, the motors of the caddy are switched off. It will only follow the transmitter automatically once again when the transmitter reaches a predetermined distance from the caddy. The ultrasonic position finding allows the caddy to be accurately kept at a predetermined minimum distance from the player.

Title: Pre-rinse for phosphating metal surfaces
Inventor: BROWN KEVIN
IPC: C11D7/16
Filed: 1994-09-12
Abstract: A method for preparing a pre-rinse composition for phosphating metal surfaces uses an aqueous suspension comprising water-insoluble manganese (II) phosphate.

Title: Method for preserving the original timebase of a program in a multiplexed communications system
Inventor: WASILEWSKI ANTHONY J
IPC: H04N7/24
Filed: 1994-07-11
Abstract: A method preserving an original timestamp value in a packet (70) of data to be transmitted from a transmission site to a reception site wherein the original timestamp value may require adjustment at the reception site to account for delays experienced by that packet (70) during multiplexing and/or transmission. The method comprises the steps of (a) defining at least first (88) and second (96) fields within the packet (70), (b) inserting, at the transmission site, an original timestamp value in the first field (88) of the packet (70), and thereafter not modifying the value in the first field (88); and (c) adding the value of any multiplexing or transmission delays experienced by that packet (70) to an initial value in the second field (96). At the reception site, the second field (96) will reflect any delays experienced by the packet (70) while the original timestamp value is preserved in the first field (88).

Title: Mobile satellite user information request system and methods
Inventor: WIEDEMAN ROBERT A
IPC: H04B7/185
Filed: 1996-10-15
Abstract: Disclosed are methods and apparatus for use in a satellite communications system  (10)  that enable a user to gain knowledge of a direction to one or more "best" satellites available to the user.

The information can be employed by the user to select for a period of time, by example, a position on an east side of a building, to move to a south-east facing window, or to take  some  other  action  that  enhances  the  user's connectivity to one or more of the satellites.
Patent CA-2189081-A1 (CA)
Inventor: HUNG CHRISTINE
IPC: F16L45/00
Filed: 1996-10-29
Abstract: A pipe fitting that allows the systematic interception and removal of solid matter from within storm drainage systems. Its topside has an opening near each end.  When the pipe fitting is installed horizontally at a slope, water that enters at one end runs out the other end.  A protrusion externally situated adjacent to each topside opening and another protrusion internally situated on the base-side of the pipe wall opposite each topside opening allow a tongue made of flexible material with a hole at each end to be attached thereto.  As water bearing solid matter enters the system, the tongue intercepts the solid matter while permitting the water to pass.  The pressure of heavy water flow forces the solid matter out through the topside opening. The diameter of the pipe fitting around each topside opening is larger than the diameter of the surrounding pipe fitting so as to prevent water from rushing out the topside openings but without disrupting the rate of flow.  This bulge or belly does not accumulate water, since the slope causes the water to systematically flow out.  Detaching the tongue permits entry into the system by a human hand or tool in order to remove blockages without the need to disassemble the system components or to enter through the mouth of the drain situated in the roof gutter.  Despite the ready availability of an entryway into the system as provided by the practice of this invention, the possibility of water leakage is minimal or none.
