Patent CA-2072068-C (CA)
Title: Electric ignition module
Inventor: ECK GARY
IPC: F02P1/08
Filed: 1991-10-21
Granted: 1995-09-05
Abstract: An electronic ignition module for an internal-combustion engine that is supplied with sparking energy from a rotating magnet includes a switchable semiconductor device through which current in the primary of an ignition coil is to be conducted. A portion of a circuit in the module senses a time when voltage across the semiconductor device approaches a maximum value, and produces a signal at that time that switches the semiconductor device out of conduction. A positive-feedback circuit is connected to increase the switching speed of the semiconductor device. The semiconductor device is protected against AC voltages of a po-larity opposite to that of the conducting direction of the semiconductor device, and is caused to advance switching time in re-sponse to increased voltages associated with high engine speed. A temperature-sensitive resistor controls spark advance in a hot engine, reducing the amount of the advance to permit restart of the engine if it is stopped briefly.

Title: Reshaping conversion process for tennis racket handles
Inventor: LAI GENHONE
IPC: A63B60/06
Filed: 1992-09-29
Granted: 1996-05-28
Abstract: The invention herein relates to a handle for sports rackets which offers an improvement of the conventional eight-surface octagonal tapered grip of conventional tennis rackets which have the shortcoming of causing calluses (hardened and thickened skin and/or medullary sheath) where the grip corners impact the hypothenar eminence of the gripping palm.   The aforesaid improved tapered grip consists of the modification of the conventional octagonal grip shape comprised of opposed horizontal surfaces into a polyhedral diamond shape, thus converting the conventional octahedral grip into a shape with multiple facets and more planar surfaces which thus minimize the number of  corners  impacting  the gripping palm and, moreover, provides more comfort and a greater number of solid gripping positions.

Abstract: Personal leather goods (PLG's) such as wallets, billfolds, pocket calendars have a portion which is required to bend repea-iedly. This bending causes cracking and extreme wear which adversely affects the look of the item and reduces its useful life. Dis-closed is a mechanical hinge which attaches to leather-like panels of such PLG's. The hinge (20) includes a set of interleaving knuckles (32) of relatively soft material which form an axial bore (34) along the length of the hinge, the bore receiving a thin pin-tle (80) made of a relatively stiff but resilient material. The pintle (80) is shorter than the axial length of the bore (34) and is held into the bore by end caps (90), either separately applied or integrally formed with the hinge leaf (30). The leaves (30) of the hinge (20) have an overall curving shape having a concave side and convex side to permit the panels (12) to which the hinge (20) is att-ached to remain parallel when materials are received between them. Alternative constructions are shown, including a third panel comprising a paper binder-like spine (45) or a body (48) made of a series of independently attached knuckles (32) and tubular body portions (40a) which in turn form a second, expandable hinge-like body.

Granted: 1997-12-30
Abstract: An emissions control system for reducing particulates from exhaust gases from a diesel engine includes dual catalyzed diesel particulate filters in joint communication with the exhaust stream and a pair of heater elements each associated with one of the filters, through which exhaust gas is transmitted and uniformly heated. According to predetermined alternating heating sequence, the exhaust gas stream through first one of the pair of filters and then through the other is heated. The differing pressure differentials across the filters, determined by the heating sequence, effectively shift the major portion of the flow of exhaust gas between the filters, so that over the alternating heating sequence the heat generated by the heating elements is sufficient to clean the filters, without the requirement for any auxiliary source of combustion air or any mechanical switching means.
