Granted: 2001-11-20
Abstract: In a multisite radio frequency simulcasting transmission system involving microwave-multiplex distribution paths to several transmitting sites, each path including manually settable amplitude and time delay devices for equalization of the modulation in signal overlap areas among the various transmitter sites, an automatic simulcast alignment device is included in each distribution path whereby transmissions between a control, point and each site transmitter are periodically tested and each path is compensated for amplitude and time delay variations to thus maintain equalized amplitude and time of arrival of the modulation in the transmitter site overlap areas. Thus, the instantaneous distribution of the FM modulation sidebands is maintained to be ideally identical in the signal overlap areas.

Title: Improved fuel vaporizer
Inventor: ROBINSON EDGAR C
IPC: F23K5/14
Filed: 1992-12-04
Granted: 2006-06-06
Abstract: A temperature compensated fuel control valve or regulator has a temperature sensor which senses the temperature of fuel entering the regulator. The temperature sensor controls the area of an orifice through which the fuel must pass in order to enter the burner. When the fuel is at low temperature, its viscosity will be higher and more of the orifice area will be exposed to the fuel. When the fuel is at high temperature, it will flow more easily and less of the orifice will be exposed to the fuel thereby allowing less fuel to pass to the burner.

Inventor: GRINHAM TERRY
IPC: C10M111/00
Filed: 1993-05-11
Granted: 2002-11-19
Abstract: A lubrication block, with or without a cavity, or a lubrication bag, for lubricating an ID surface of a tyre and an OD surface of a plurality of pads of rotary trunnion supported equipment, such as a kiln, cooler, dryer, reactor, granulator and ball mill operating at temperatures from 100°F to 500°F or higher. The tyre has inner and outer faces, and the inner face of the tyre is slipped over the plurality of pads or filler bars welded to an outer shell of the rotary equipment. The lubrication block or bag is sized so as to be inserted in between the pads. The lubrication block comprises a lubricant and a solid carrier for said lubricant. The carrier is selected from the group consisting of waxes such as paraffin, polymers, copolymers such as ethylene or polyethylene glycol or mixtures thereof, and the lubricant comprises powdered carbon and a soft metal powder (e. g. copper, zinc, aluminum) or a noble metal powder (e.g. silver, copper). The lubrication bag contains a lubricant like the lubrication block and is made of a material selected from the group consisting of plastic materials such as polymers, copolymers or mixtures thereof.      The carrier or the material of the bag melts and vaporizes at the temperature of the tyre, leaving very little harmful residue on the tyre except for the powdered carbon, the soft metal powders and the noble metal powders. In this way, the powdered carbon and the metal powders are capable of lubricating the ID surface of the tyre uniformly, without having to use messy hoses, pumps, or kegs containing the lubricant, in order to apply the lubricant to the ID surface of the tyre.

Filed: 1992-09-04
Granted: 2007-04-10
Abstract: L'invention concerne les procédés qui permettent de démoduler de manière numérique une modulation complexe permettant de transmettre des paramètres différents. Elle consiste à effectuer un filtrage en bande de base (201) du signal d'entrée, une démodulation complexe (202) d'une première sous-porteuse à la fréquence Fp pour obtenir après élévation au carré (207) un signal de correction. On démodule ensuite le signal d'entrée autour d'une fréquence exactement égale au double de la fréquence de la premiére démodulation pour obtenir des signaux de sortie présentant une erreur de fréquence par rapport à 2Fp. Cette erreur de fréquence est corrigée par multiplication (213) avec le signal de correction de fréquence élaboré précédemment. On filtre ensuite ( 214, 215) à une fréquence inférieure à 1 Hz le signal ainsi corrigé pour obtenir un signal donnant l'erreur de phase à la fréquenee 0, c'est-à-dire celle de la sous-porteuse à 2Fp. Ce signal permet de corrige r en phase les signaux préalablement corrigés en fréquence pour obtenir deux signaux complémentaires l'un de l'autre et transmis par modulation en quadrature autour de la fréquenee 2Fp. Elle permet de démoduler les signaux omnidirectionnels et dipolaires provenant d'une bouée d'écoute sous-marine.

Granted: 1999-06-15
Abstract: A digital copier includes an automatic copy quality correction and calibration method that corrects a first component of the copier using a known test original before attempting to correct other components that may be affected by the first component. Preferably, a scanner subsystem is first calibrated by scanning a known original and electronically comparing the scanned digital image with a stored digital image of the original. A hard copy of a known test image is then printed by a printer subsystem and the calibrated scanner subsystem scans the hard copy. The scanned digital image is electronically compared with the test image and the printer subsystem is calibrated based on the comparison.
