Patent CA-2221475-A1 (CA)
Title: Variable displacement compressor
Inventor: NAGAI HIROYUKI
IPC: F04B27/14
Filed: 1997-11-19
Abstract: A housing of a compressor has a shutter chamber for accommodating a shutter.  The shutter moves between a closed position, where the shutter stops flow of gas from an external circuit into a suction chamber, and an open position, where the shutter permits the gas flow in response to the tilting motion of a swash plate.  A coil spring, which has a conical shape, is located in the shutter chamber to bias the shutter in a direction toward the open position from the closed position.  The spring is arranged to prevent the spring from sliding against the inner wall of the shutter chamber when the spring is expanded or contracted by movement of the shutter member.

Filed: 1998-01-27
Abstract: An apparatus and method for removing gasses and particulate matter from automobile exhaust. The apparatus includes a heat exchanger connected to an automobile exhaust system for cooling exhaust and condensing at least a portion of the exhaust into a liquid condensate. A fluid separator is connected to the heat exchanger and separates the condensate and at least some of the particulate matter from non-condensed gasses. The condensate is passed into a fluid holding tank. The condensate is treated in a first chemical reactor which neutralizes any acids present in the liquid. Non-condensed gasses flow into a second chemical reactor connected to the fluid separator. Gasses are reacted in the second chemical reactor with a substance which absorbs carbon monoxide and carbon dioxide and removes more of the particulate matter. The treated gasses are vented to atmosphere through an exhaust outlet.

Title: Weaving machine with pneumatic weft thread insertion
Inventor: SPEICH FRANCISCO
IPC: D03D49/70
Filed: 1995-10-10
Abstract: The invention concerns a mechanical loom comprising a weaving reed (8) and a weft thread guide device (32) which are interconnected so as to pivot between an insertion position and a stop position.     In order to insert the weft, there are provided a stationary weft-insertion device (14) with at least one blower nozzle (22) for inserting a weft thread (38) into the guide duct (36), as well as a thread clamp (16) and scissors (15). The thread clamp (16) is coupled with the weaving reed in order to clamp an inserted weft thread (38) and convey it synchronously with the guide duct (36) from the insertion position to the stop position. The scissors (15) are arranged downstream of the thread clamp (16) in the stop direction in order to cut off the weft thread immediately after it has been clamped. Since the insertion device is stationary and the thread clamp and scissors are operatively associated with the weaving reed, control of the loom is simplified such that up to sixteen different weft threads can be inserted.

Title: Ntsc interference detectors using comb filters that suppress dtv pilot carrier to extract ntsc artifacts
Inventor: LIMBERG ALLEN LEROY
IPC: H04N5/44
Filed: 1998-09-16
Abstract: A first comb filter differentially combines an I- or Q-channel baseband signal supplied as input signal to a co-channel NTSC interference detector for a DTV receiver with that signal as subjected to a first amount of differential delay. This generates a first comb filter response in which artifacts arising from synchrono us detection of the co-channel interfering analog television signal are suppressed. The detector includes a second comb filter that combines the input signal with that signal as subjected to a second amount of differential delay to generate a second comb filter response in which artifacts of the co-channel interference are reinforced. The f irst and second comb filters both use the same type of linear combiner so the direct term of input signal is treated similarly in the first comb filter response and in the s econd comb filter response. First and second amplitude detectors detect the respective amplitudes of these comb filter responses. An amplitude comparator compares the first and second amplitude detection responses and indicates, when and only when the first and second amplitude detection responses differ more than a prescribed amo unt, that co-channel interference is of sufficient strength to be objectionable.

IPC: H01Q19/17
Filed: 1998-09-22
Abstract: An antenna system has a reflector illuminated by a primary feed for producing a primary beam.   The reflector is illuminated further by a secondary feed formed of an array of  secondary  feed  elements  of  which  the  respective electromagnetic signals are adjustable in terms of their relative amplitudes and phases to produce a secondary beam with  sidelobes  oriented  in  directions  away  from  the directions  of  the primary  beam.    Spacing  among  feed elements of the secondary feed array  is  selected for further  control  of  orientation  of  sidelobes  of  the secondary beam.  Highest efficiency is attained for signals of the primary feed by configuring the reflector for forming the primary beam,  while the secondary beam is produced with lower efficiency but with isolation from the primary beam.  The surface of the reflector is contoured to provide  maximum  primary-beam  efficiency  and  minimal primary-beam sidelobes in the direction of the secondary beam.
