Patent CA-2247484-C (CA)
Inventor: PREVOST JEAN
IPC: E01C13/00
Filed: 1998-09-21
Granted: 2001-07-24
Abstract: The invention relates to a synthetic grass turf assembly for installation on a supporting soil substrate to provide a game playing surface that combines the feel of natural turf with the wear resistance of synthetic turf. The turf assembly includes a pile fabric with a flexible sheet backing and rows of upstanding synthetic ribbons representing grass blades, extending upwardly from an upper surface of the backing. A  unique infill layer of multiple distinct graded courses of particulate material is disposed interstitially between the upstanding ribbons upon the upper surface of the backing and of a depth less than the length of the ribbons. A base course is first placed upon the top surface of the backing and consists exclusively of hard sand granules.  A middle course of intermixed hard sand and resilient rubber granules with relative weight ratio of 3 to 1 is then placed upon the base course. A top course exclusively of resilient rubber granules is then placed upon the middle course. The relatively thin top course that is in contact with users, has a high resilience where contact occurs and low abrasion due to exclusive use of rubber. The base sand course provides weight to hold the turf in place and to quickly drain the surface. The middle layer of mixed sand and rubber granules acts as a buffer to keep the base sand and top rubber courses separate avoiding migration of abrasive sand towards the top surface level. An upper portion of the synthetic ribbons extends upwardly from the top surface of the top course 0.25 to 1.00 inches to give the appearance of grass blades. Preferably the upper portion of the synthetic ribbons is fibrillated, split or frayed on site by passing over the installed surface with a stiff wire brush. The fibrillated surface has a slight resilience and visually appears like a natural grass turf. The criss-crossed fibrillated fibres contain the top course rubber granules while allowing dislodged rubber granules to fall back into place and permitting water to drain through to the sand containing courses.

Title: Capless refueling assembly
Inventor: GRUBER HERBERT
IPC: B60K15/035
Filed: 1998-10-16
Granted: 2008-12-02
Abstract: A capless refueling assembly for opening and closing a filler neck of a gas tank. The refueling assembly includes a housing attached to the filler neck. A lid is pivotally mounted to the housing between open and closed positions for facilitating the opening and closing of the filler neck. A valve mechanism is movably mounted to the housing between seated and unseated positions for selectively releasing pressurized fluid from the filler neck. The refueling assembly is characterized by an actuation device automatically moving the valve mechanism from the seated position to the unseated position while the lid remains in the closed position. Accordingly, any pressurized fluid within the filler neck is vented to a safe area, preferably a carbon canister, before the lid is moved to the open position.

Granted: 2004-08-03
Abstract: A telephone communications switching system incorporating echo cancellers that may be replaced by other echo cancellers, and a method for replacing such echo cancellers are disclosed. The system comprises a control module for receiving and switching call data; and active and redundant echo cancellers. Under normal operation, an active echo canceller cancels echo in a call. A processor on the control module monitors the system and in the response to a sensed trigger event activates the redundant echo canceller and switches call data at the input of the active echo canceller to inputs of both the active and redundant echo cancellers. The processor then waits a determined amount of time; and thereafter disconnects the output of the active echo canceller from the control module and connects the output of the redundant echo canceller to the control module. By waiting, the processor allows the redundant echo canceller to become ready to cancel echo, before connecting the output of the redundant canceller to the control module. This may reduce the amount of time echo cancelling is not available for the call.
