Patent CA-2219326-A1 (CA)
Inventor: SVENSSON KJELL
IPC: H02J5/00
Filed: 1997-11-13
Abstract: ABSTRACT            A PLANT AND METHOD FOR TRANSMITTING ELECTRIC POWER   A method and apparatus for eliminating overmodulation in a power plant is provided. The power plant has a direct voltage network connected to at least one alternating voltage network through a station. The station is adapted to transmit power between the direct voltage network and the alternating voltage network and includes at least one converter. The converter is adapted to convertdirect voltage into alternating voltage and convert alternating voltage into direct voltage. The method comprises the steps of calculating a reference alternating voltage and measuring a direct voltage between two poles of a direct voltage side of the station. The reference voltage is divided by half of the direct voltage and this quotient is compared with a predetermined value. When the quotient exceeds the predetermined value, a first signal is sent to a means for controlling the converter. In response to receiving the first signal, the converter is controlled to increase consumption of reactive power on the alternating voltage side of the station.

Title: Self-limiting heaters
Inventor: SELLARS BRIAN G
IPC: H05B3/14
Filed: 1997-12-05
Abstract: A self-limiting electric heater comprising a PTC element in the form of a body having first and second faces opposite one another and first and second ends opposite one another and at least one series element in the form of a layer (preferably a coating) on the first face so as to be in intimate thermal contact with it. This layer is in effective electrical contact with the PTC material only in the neighbourhood of the first end and external connections are made to the PTC material and to the layer, both in the neighbourhood of the second end.  Preferably the external connection of the PTC material in the neighbourhood of the second end is made by a further series element in the form of a similar resistive layer in the second face of the PTC element and in effective electrical contact with it only in that neighbourhood and an external electrical connection to this further series element in the neighbourhood of the said first end; the structure thus becomes at least in general terms rotationally symmetrical.  Insulating the series resistance layers electrically from the PTC layers in this way (but maintaining thermal contact) stops the PTC material from tending to short out the series resistances when it is cold and has low resistance, minimising inrush current.  It also allows the current path through the PTC material to be long and of small cross-sectional area, increasing the high-temperature electrical resistance of the PTC element and minimising the effect of inhomogeneity.

Patent CA-2226909-A1 (CA)
Inventor: LOEFFLER JOHN M
IPC: F16H63/36
Filed: 1998-01-14
Abstract: An interlock assembly for a vehicle transmission prevents more than one of a plurality of shift rails from being simultaneously moved axially out of a central neutral position to a gear engaging position. The interlock assembly includes an interlock plate having four semi-circular cut-outs (one for each of the shift rails) and two relative large interior openings. The interlock assembly further includes a backing plate which is somewhat smaller than the interlock plate and has two relatively small interior openings. A pair of threaded fasteners extend through the small openings of the backing plate and through respective spacer bushings disposed in the large interior openings of the interlock plate into threaded engagement with the housing of thehydraulic actuator. The spacer bushings prevent the interlock plate from being frictionally engaged between the backing plate and the housing of the hydraulic actuator. As a result, the interlock plate is loosely supported on the threaded fasteners and can slide freely in any direction relative thereto. Each of the four cut-outs of the interlock plate is formed having opposed tapered edges which cooperate with tapered grooves formed on the exterior surfaces of the four shift rails. When any one of the four shift rails is moved out of the central neutral position, the interlock plate slides to extend into the grooves of the other three shift rails. Thus, the interlock plate prevents the other shift rails from moving until all are in the central neutral position.

Title: Transceiver apparatus employing wideband fft channelizer and inverse fft combiner for multichannel communication network
Inventor: CARNEY RONALD R
IPC: H04B1/38
Filed: 1994-10-18
Abstract: A physically compact, multichannel wireless communication transceiver architecture employs overlap and add or polyphase signal processing functionality, previously applied to narrowband speech analysis research, for wideband signal processing. A receiver section receives a plurality of multiple frequency communication channels and outputs digital signals representative of the contents of the plurality of multiple frequency communication channels. The receiver section contains an FFT-based channelizer that processes the digital signals output by a wideband digital receiver and couples respective channel outputs to a first plurality of digital signal processor units, which process (e.g. demodulate) respective ones of the digital channel signals and supply processed ones of the digital channel signals at respective output ports for distribution to as attendant voice/data network. On the transmit side, a transmit section contains a plurality of digital signal processors, respectively associated with respective ones of a plurality of incoming (voice/data) communication signals to be transmitted over respectively different frequency channels. Their processed (modulated, encoded) outputs are supplied to an inverse FFT combiner. The FFT combiner supplies a combined multichannel signal to a wideband transmitter which transmits a multiple frequency communication channel signal. Each of the channelizer and combiner may be implemented using overlap and add or polyphase filtering.

An embodiment also provides a transport system for the delivery of video signals to a device, for the return of analog signals from the device, and for the transmission of digital signals to a signal destination. This embodiment includes a broadband communications module that receives video signals from a signal source and delivers the video signals to the device. The module also receives analog signals from the device and transmits the analog signals to an interface. The interface receives the analog signals, converts the analog signals to digital signals and transmits the digital signals to an optical network unit or a communications network connection card for further transmission to a signal destination.

Title: Suspension system with laminated beam
Inventor: VANDENBERG ERVIN K
IPC: B60G7/00
Filed: 1997-05-08
Abstract: A vehicle suspension system having a pair of hanger brackets (5) and a pair of beams (15). A first end of each beam is attached, via a bushing sleeve to each hanger bracket, and an axle (19) is rigidly attached to the second end of each beam. Each beam is manufactured from a plurality of layers of laminate material which extend circumferentially around the axle and the bushing sleeve (30). An adhesive layer extends between the bushing sleeve and axle, and the layers of laminated material, for securing the bushing sleeve and axle to the beam. Inasmuch as the laminate material and adhesive have relatively low modulus of elasticity, these materials flex in response to movement of the axle, thereby assuring that the connection between the laminate beam (15) and the axle (19) remains stable, even as the axle moves in response to forces acting thereon. In another embodiment of the invention, each beam (47) is integrally formed with an air spring piston (48). In another embodiment of the invention, a parallelogram suspension is provided with a pair of parallel and spaced-apart control arms (62) manufactured of laminate material. Alternatively, the control arms of the parallelogram-type suspension may be integrally formed with a stabilizer bar (68) extending therebetween. In alternative embodiments, a pair of air spring pistons (48) may be mounted on the stabilizer bar (68), substantially reducing the weight and cost associated with the manufacture and operation of air spring suspension systems.
