Title: Modulator for electromagnetic signals transmitted by a contactless transmission/reception system
Inventor: PARRAULT OLIVIER
IPC: H04B1/59
Filed: 2002-09-13
Abstract: The invention relates to a device for transmitting data by means of electromagnetic wave radiation in a contactless transmission/reception system to a contactless object. The data bits transmitted correspond to the alternation of a first time interval during which the electromagnetic waves are transmitted at a pre-determined carrier frequency and a second cut-off time interval during which the transmission of electromagnetic waves at the pre-determined carrier frequency is cut-off. According to the invention, during said second cut-off time interval, generation means (40, 42, 44, 46, 48) are used to generate electromagnetic waves having a frequency that is double the pre-determined carrier frequency, thereby causing an attenuation of the field radiated by the antenna, said attenuation being greater than a pre-determined value such as 30 dB.

Patent CA-2433202-A1 (CA)
Title: Universal putter
Inventor: JACKSON GEORGE W
IPC: A63B53/02
Filed: 2003-06-25
Abstract: A putter has an elongated head with a face along a long side of the head and an end surface along a short side of the head. The shaft can be positioned to strike a ball with either the face or the end surface. The end surface may have a loft of 5 degrees or more. The shaft is held in each position such that it does not move appreciably while putting, but can be moved to another position by a golfer, optionally with or without tools. In some embodiments, all contact between the shaft and the head is made through one or more resilient, non-metallic materials such as rubber. In some embodiments, a ball on the end of the shaft is held in a cavity in the head by an annular nut. O-rings or other elements separate the ball from components fixed to the head and the nut can be tightened or loosened to adjust the friction provided by the O-rings or other elements. In some embodiments, the shaft can alternately be made fixable or moveable relative to the head by manipulating, for example twisting, the shaft. In other embodiments, a golfer can change the loft of a face or end of the putter without moving the shaft, by using a wedge that may be removeably affixed to the face or end.

Title: Modular voc entrapment chamber for a two-chamber regenerative oxidizer
Inventor: CASH JAMES T
IPC: F23L15/02
Filed: 2002-06-18
Abstract: Regenerative oxidizer including an entrapment chamber and damper assembly, as well as a method of oxidizing volatile organic compounds in a gas using such apparatus. To improve the VOC destruction efficiency and eliminate opacity issues resulting from heat exchange matrix regeneration, untreated fluid can be diverted away from the oxidizer exhaust stack and directed into a "holding vessel" or VOC entrapment chamber. The assembly utilizes a single damper in order to divert the exhaust flow from the oxidizer either to exhaust or to the entrapment chamber. The entrapment chamber preferably has a modular construction, which facilitates expanding or decreasing the volume of the chamber. The design facilitates installation and can be retrofitted on existing equipment. The damper diverts the flow of gas with minimal or no negative impact on the process flow.

Patent CA-2460930-A1 (CA)
Inventor: MALKERSON ERIC E
IPC: B63B21/08
Filed: 2004-03-15
Abstract: A cam cleat has at least one cam mounted on a base. The cam has a fairlead projection that is spaced from the base and that rotates with the cam. When the cam is in its idle position with no line gripped by a jaw of the cam, the fairlead projection is rotated out of alignment with a gripping path that a line to be gripped by the cam cleat occupies. When a line is gripped by the cam, the cam rotates into a gripping position where the fairlead projection is rotated into alignment with the gripping path. The fairlead projection is aligned with the gripping path when the line is gripped in the cam's jaw. When so aligned, the fairlead projection resists tension in the line directed upward from the cam cleat that might otherwise cause the line to slip from the grip of the cam's jaw.
