Title: Electro-hydraulic operating system for extensible boom crane
Inventor: BARTHALOW HENRY D
IPC: B66C23/687
Filed: 1996-10-02
Abstract: An electro-hydraulic operating system for an extensible boom includes one or more hydraulic cylinders for imparting relative motion between the boom sections to retract the boom according to an electronically stored program of sequences of movement and speeds. A source of pressurized hydraulic fluid is fed through appropriate control valves which include solenoid valves in fluid communication with a source of pressurized hydraulic fluid. The solenoid control valves are supplied with control currents proportional to the desired flow rates of fluid to the hydraulic cylinders in order to achieve speed and position control according to the stored program. A metering valve structure is provided for operation in conjunction with the solenoid control valves. The metering valve includes an associated pilot valve which receives variable pressure signals from the solenoid control valves to achieve the metering of fluid to the hydraulic cylinders in proportion to the characteristics of the control current supplied to the solenoid valves. The electrical control signals are such that the hydraulic cylinders may move associated boom sections at gradually increasing speeds during a starting period of any cycle of movement of the section, at a substantially constant speed during an intermediate period of movement and at a gradually decreasing speed during a stopping period preceding the end of the cycle of movement, thereby providing soft start and soft stop of the sections.

Title: Thin-film antenna device for use with remote vehicle starting systems
Inventor: DERY NORMAND
IPC: H01Q13/26
Filed: 1997-02-18
Abstract: The present invention relates to a thin-film antenna device particularly well suited for use with remote vehicle starting systems. The antenna device includes an electrically conducting film printed on an insulating substrate that can be bonded to any suitable supporting surface, such as the windshield of a vehicle. The electrically conductive film is protected by an outer protective coating along its entire surface except at two areas that form contact pads for receiving the terminals of a signal processing unit such as a radio receiver, demodulator, filter and amplifier, among many others. The signal processing unit is mounted to the same surface to which the antenna device is secured by a releasable attachment system such as a hook and loop type fastener. In a typical installation, a patch of hook-type material is adhesively bonded to the supporting surface overlying the antenna device. The patch of hook-type material includes a pair of apertures registering with the contact pads of the antenna device. The signal processing unit includes a printed circuit board to which is bonded a patch of loop-type material. A pair of resilient three-dimensional contact elements project through the loop-type material patch such that when the two patches are mated the contact elements pass through the apertures of the hook-type material patch and engage the contact pads of the antenna device.

Title: Unvented heating appliance having system for reducing undesirable combustion products
Inventor: BARKHOUSE SYDNEY R
IPC: F24B1/18
Filed: 1997-03-24
Abstract: A gas-fueled heating appliance having a system for reducing the amount of undesirable combustion products released to the site in which the appliance is installed. The appliance includes a firebox partially surrounded by a heat exchanger. Ambient air is drawn into the heat exchanger below the firebox and a portion of the ambient air enters the firebox to assist in combustion, and the remaining portion travels through the heat exchanger to be heated by convection before being combined with combustion gasesexiting through the top of the firebox. The heat exchanger creates a low pressure area relative to the firebox which induces a draft from the firebox into the heat exchanger and ultimately to the ambient environment through an exit provided above the firebox. A carbon monoxide catalyst element is provided in the exit passageway from the firebox to the heat exchanger to oxidize carbon monoxide into carbon dioxide and filter away airborne particulates which would otherwise be released to the ambient air.
Patent CA-2207126-A1 (CA)
Title: Optical fibre transmission systems
Inventor: ROBERTS KIM BYRON
IPC: H04B10/18
Filed: 1997-06-05
Abstract: An optical transmission system includes means for measuring optical dispersion in the optical path, and a controllable element such as a dispersion compensator, operable in dependence on the measured value of dispersion. A low frequency dither on the optical signal causes timing jitter which varies according to the dispersion in the optical path. The timing jitter is extracted from a clock signal recovered from the optical signal. This jitter is correlated with the original dither to remove jitter effects caused by other mechanisms.      Thus a value for dispersion is derived which can be used for monitoring or control purposes.
