Filed: 1997-06-17
Granted: 2001-05-01
Abstract: A circuit (10) for predistorting a signal to be transmitted via a non-linear channel (18) comprises an envelope detector (24) for detecting an envelope of the signal (v). A quantization means (22) for forming quantized envelope values on the basis of the detected envelope is connected to the envelope detector (24) as well as to a table (16) for supplying complex predistortion coefficients which depend on said quantized envelope values and on a previously detected transmission function of the non-linear channel. An evaluation circuit (14) separated from said non-linear channel (18) and used for the complex evaluation of the signal (v) to be transmitted via the non-linear channel (18) with the complex predistortion coefficients permits the distortion introduced by the non-linear channel (18) to be substantially compensated according to amount and phase.

Title: Separator for fuel cell and manufacturing method for the same
Inventor: MIZUNO SEIJI
IPC: H01M8/02
Filed: 1999-01-18
Granted: 2004-03-16
Abstract: A separator for a fuel cell is manufactured by preparing a raw material powder, uniformly mixing the prepared raw material to be formed into a slurry, and charging the raw material powder derived from granulation into a metal mold for heat press forming. The raw material is obtained by adding to carbon powder a binder containing a mixture of phenolic resin and epoxy resin. Therefore the heat press forming step does not cause the binder to generate gas, thus allowing manufacturing of a separator exhibiting sufficient gas-impermeability.

Abstract: Coolant pump service in a crowded engine compartment is provided by forming the side wall of the pump drive pulley with a centralized and radially lobed opening which can accommodate the radial arms of the drive hub that are normally connected by screws to the pulley side wall. The drive hub is fixed to the outboard end of the coolant pump drive shaft that extends through the housing of the pump that is removably secured by screws to the block of an internal combustion engine. The pump impeller is mounted on the inboard end of the drive shaft for fluid pumping operation in a coolant-receiving cavity in the coolant circuit of the engine. In the event of interference, which prevents or hampers the removal of the pulley axially from the drive shaft, the hub screws are removed and the pulley is turned into alignment with the lobes of the opening so that the pump housing screws are accessible. These screws are then removed so that the pump can be manually removed from the clearance between the engine and the frame side rail or other interfering component.

Title: A method and apparatus for rejecting rain clutter in a radar system
Inventor: BOHLEY ERIC P
IPC: G01S13/931
Filed: 1999-07-06
Granted: 2005-03-22
Abstract: A method and apparatus for detecting the presence of objects in a vehicle operator's blind spots. The apparatus comprises a side-facing Doppler radar system using continuous wave (CW) transmission with frequency modulation (FM) operation from a frequency modulation switching technique. The radar system determines the presence, range and closing rate of detected targets. The radar system detects targets even when operated in adverse weather conditions and will not generate false warnings due to rain clutter caused by wet roads and other wet surroundings. The radar system uses ranging techniques to reject false targets that are detected outside of a predetermined target detection zone. In accordance with the present invention, the radar system indicates that a target is detected if and only if any part of the target is within the detection zone and it: (1) remains in front of the antenna for at least TH1 seconds; (2) is at a range between Rangemin and Rangemax; and (3) is moving faster than Closing-Speedmin relative to the antenna. By rejecting targets that are closer than Rangemin feet to the antenna, false alarms due to rain clutter are dramatically reduced. Also, by rejecting targets that are further than Rangemax feet from the antenna, the radar system reduces false alarms caused by wet foliage and other wet "non-road" surroundings. In one embodiment, the radar system uses a patch array antenna oriented into a diamond-shape configuration to effectively create a natural linear amplitude taper that aids in rejecting clutter caused by wet road surfaces.

Title: Process for simultaneous extraction of dispersed and dissolved hydrocarbon contaminants from water
Inventor: PACE GARY WILLIAM

Filed: 1997-02-28
Granted: 2006-05-02
Abstract: The invention is a new process for simultaneous extraction of dispersed and dissolved hydrocarbon contaminants from water. The process is based on the principle of injecting natural hydrocarbon gas to the water feed stream under pressure and temperature conditions which permits the gas to act as a solvent for dissolved and dispersed hydrocarbon contaminants. The dispersed particles "swell" and have a reduced density which markedly improve the efficiency of the downstream separation by liquid-liquid-hydrocyclones.

Abstract: A process for the preparation of a catalyst useful for conducting carbon monoxide conversion reactions, especially a Fischer-Tropsch catalyst, use of the catalyst for conducting such reactions, especially Fischer-Tropsch reactions, and the composition produced by said process. In the preparation of the catalyst, a solution of a polyol is employed to impregnate and disperse a compound or salt of a catalytic metal, or metals, e.g., copper or an Iron Group metal such as iron, cobalt, or nickel, or in a preferred embodiment both a compound or salt of rhenium and a compound or salt of a catalytic metal, or metals, e.g., copper or an Iron Group metal such as iron, cobalt, or nickel onto a refractory inorganic oxide support, e.g., titania. The rhenium, when prese nt only in small amount permits full and complete reduction of the catalytic metal, or metals, dispersed by the polyol. Higher catalyst activities with lower rhenium loadings are thus achieved than in previous preparations where higher concentrations of rhenium were required t o both effectively disperse, and reduce the catalytic metal, or metals, during the preparation. Surprisingly, as little as about 1/10 of the rhenium is required to accomplish the reduction promotion where the dispersion is effected with the polyol.
