Abstract: In a grain cart equipped with a lower horizontally-disposed input drag auger, a vertically disposed lift auger, and an upper horizontally disposed discharge auger, a unique drive train is used. The lift auger and the discharge auger can be activated independently of the input auger in order to empty their contents on start-up of the grain cart discharge system. By so doing the strain on the drive train is considerably lessened thus permitting very large grain carts to be emptied without damage to the drive train system. A hydraulic cylinder activates a belt-tightener between a drive sheave and a driven sheave. The driven sheave is attached to the axis of the drag auger. When the hydraulic cylinder is extended, pressure exerted on the belt causes the input auger to rotate and to feed the lift and discharge augers.

Abstract: Apparatus for spraying an ice surface with a white paint comprises a trailer having a tank carried on the trailer, a pump and a boom having a plurality of spray nozzles. The tank has a large opening in the top for receiving bags of paint pigment. The pump is a high capacity pump which generates a flow rate significantly greater than necessary to supply the nozzles. The excess is returned to the tank through a jet mixing system including four arms each having a pair of jet nozzles. A mixing wand is also provided which receives mixed materials from the pump for the jet nozzle for stirring within the tank. The nozzles are closely spaced so as to generate an overlapping spray pattern. The nozzles generate a fine mist and are directed slightly upwardly and rearwardly.

Abstract: A time-duplex wireless telephone for reducing magnetic coupling between the wireless telephone and a hearing aid to prevent hum pick-up in the hearing aid. The wireless telephone includes a battery, a rad io circuit, and a humbucking coil. The radio circuit is connected to the battery and has a transmit mode where transmit signals are transmitte d and a receive mode where received signals are received. The radio circuit intermittently is switched between the transmit mode and t he receive mode. The radio circuit generates a transmission magnetic field when the radio circuit is transmitting transmit signals. A humbucking coil is connected in the radio circuit to generate a cancellation magnetic field that is directly proportional to the transmissio n magnetic field and in antiphase with the transmission magnetic field. The cancellation magnetic field at least partially cancels the transmission magnetic field and reduces magnetic coupling between the wireless telephone and a hearing aid used in conjunction with the wireless telephone.

Title: Reversing flow catalytic converter for internal combustion engine
Inventor: KLOPP GERHARD O
IPC: F01N3/26
Filed: 1998-10-23
Granted: 2007-05-22
Abstract: A compact reversing flow catalytic converter for reducing noxious substances in exhaust gases produced by internal combustion engines is described. The catalytic converter includes a valve unit which reversibly directs exhaust gases through a container filled with catalytic material. The container defines a U-shaped gas passage which communicates with two ports at a top of the container. The valve unit is mounted to the top of the container and includes an intake and an exhaust cavity. The valve unit includes a valve disk having two openings therethrough and rotates around a perpendicular central axis between a first and second position. In each position, each opening communicates only with one of the cavities and one of the ports. In the first position, the exhaust gases enter the exhaust cavity from an exhaust pipe and pass through one of the openings into the gas passage where they contact the catalytic material as they travel through the U-shaped gas passage and enter the exhaust cavity. In the second position, the two openings are rotated 90° so that each opening communicates with the same cavity but a different one of the ports. Therefore, the gas flow through the U-shaped gas passage is reversed. The advantage is a compact, reliable, highly-efficient catalytic converter that is inexpensive to manufacture.

Title: Detecteur d'attitude de satellite a imagerie thermique

Abstract: L'invention porte sur un procédé permettant de distinguer le contour d'un objet, et l'objet lui-même, d'un fond, consistant à détecter le rayonnement électromagnétique d'au moins deux champs de vision englobant sensiblement le contour de l'objet et le fond voisin du contour apparaissant dans un détecteur (36) sous forme d'images en superposition ou en recouvrement. Le procédé consiste à corréler les transitions spatiales en intensité des images superposées dans le détecteur avec le contour de l'objet. Le détecteur utilisé pour déterminer l'attitude d'un satellite par rapport a la terre, est un détecteur (36) du type thermique à infrarouge, avec lequel on obtient un fort contraste entre le rayonnement thermique de la terre et l'espace froid. L'invention présente un procédé et un dispositif simples et efficaces de détermination de l'orientation et/ou de l'attitude d'un satellite par rapport à une cible thermique émettrice d'infrarouge. Le détecteur comporte un miroir segmenté (32) en forme de limbe fournissant plusieurs champs de vision à l'intérieur du champ visuel qui sont superposés sous forme d'images dans un détecteur classique (36). La résolution souhaitée peut être obtenue pour une large plage d'altitudes orbitales opérationnelles. L'attitude du satellite peut varier d'un angle important par rapport à l'orientation minimale tout en permettant une détermination précise de l'altitude. L'existence de plusieurs canaux modulaires assure la redondance et une plus grande précision, tout en offrant la possibilité de configurations diversifiées. Le recours à des réseaux de microbolomètres non refroidis comme détecteurs d'imagerie permet de se passer d'équipement additionnel de refroidissement; on obtient ainsi un détecteur économique, de taille réduite, de faible masse, avec une flexibilité de configuration et sans pièces mobiles.

Abstract: The temperature of a battery in a hybrid car is supervised by temperature sensors. When the temperature of the battery is at a temperature not exceeding a predetermined temperature, a battery ECU issues a command to a control CPU to perform forcible charge/discharge of the battery to raise the temperature of the battery. When raising of the temperature is performed by charging, a requested output from an engine is increased as compared with a usual state. In such a state, motor-generators are operated as generators so as to generate electric power and charge the battery by passing an electric current to the battery rather than generating a driving force. When raising of the temperature is performed by discharging, the requested output from the engine is reduced as compared with the usual state. In this case, the motor-generators are operated as drive motors to consume electric power so as to draw electric current from the battery causing discharge of the battery. The electric current allowed to flow at. this time causes internal resistance to be generated in the battery that heats the battery from an inside portion thereof. Thus, an apparatus for controlling a charge/discharge state of a hybrid car can be provided that quickly and easily controls the temperature of the battery to a predetermined temperature.

Abstract: A power assisted liposuction/lipoinjection handpiece includes a handle (12) which provides power to reciprocate a cannula (10) back and forth during surgery. The cannula (10) can be connected to the handle (1 2) by a connector (24) that is affixed to, integrally formed with, or selectively joinable to a reciprocating member (14). Benefits in sterilization, distribution and surgical use can be realized when the cannula (10) and connector (24) are joined together, such that the surgeon merely needs to remove the cannula (10) from the package and connect it to a reciprocating member of a powered handle (12). The handle (1 2) may be configured such that the reciprocating member (14) is selectively detachable; thereby, allowing the handle (12) to be used for additional surgical procedures such as sawing or drilling. A vacuum hose (26) is connected to the cannula (10) such that vacuum pressur e can be exerted through the cannula (10) for aspirating severed fat tissue. Preferably, the connector (24) radially offsets the cannula (10) from the reciprocating member (14) to a position which is axially in alignment with the vacuum hose (26); thereby avoiding bend regions and enhancing suction.
