Title: Rectifier circuit for supplying dc voltage to an intermediate circulating current circuit
IPC: H02M7/757
Filed: 1988-07-16
Granted: 1992-03-18
Abstract: The rectifier circuit is universally suitable for connection to a DC or AC network and is particularly suitable for multi-system rail vehicles. In this case, the circuit operates with an AC supply as a four-quadrant adjuster and with a DC supply as a step-up or step-down series circuit. The circuit has four arms in a bridge circuit, each arm consisting of a valve (T1...T4), which can be switched on and off, with an anti-parallel, uncontrolled rectifier (D1...D4). Between the connections (F,G) on the DC side of two arms of equal polarity (T1/D1/T3/D3), a switch contact (17) is provided. When the switch contact (17) is open, the supply from the DC network passes through the DC connections (D, E) of the rectifier, whereas the AC connections (A1, B1, A2, B2) are short-circuited. To supply the circuit from the AC network, the switch contact (17) is closed. <IMAGE>

Abstract: A ceramic-reinforced aluminum matrix composite is formed by contacting a molten aluminum-magnesium alloy with a permeable mass of ceramic material in the presence of a gas comprising from about 10 to 100% nitrogen, by volume, balance non-oxidizing gas, e.g., hydrogen or argon. Under these conditions, the molten alloy spontaneously infiltrates the ceramic mass under normal atmospheric pressures. A solid body of the alloy can be placed adjacent a permeable bedding of ceramic material, and brought to the molten state, preferably to at least about 700 DEG C, in order to form the aluminum matrix composite by infiltration. In addition to magnesium, auxiliary alloying elements may be employed with aluminum. The resulting composite products may contain a discontinuous aluminum nitride phase in the aluminum matrix and/or an aluminum nitride external surface layer.

Abstract: To remove disturbing wax particles and for increasing the specific volume the short fiber fraction is subjected to a thermal treatment, especially by application of water vapor or steam, in a heater, such as a worm heater throughout a defined residence time and a defined temperature. With relatively low energy expenditure the distrubing wax particles are eliminated in such a manner that no wax spots or speckles can be discerned in the finished product. The specific volume of the short fiber fraction is appreciably increased while obtaining a predetermined strength.

Abstract: In a group of elevators with double cars, the assignment of such double cars to floor calls takes place at scanner positions  alpha in two procedural steps, according to two parameters: primarily by assignment of the individual cars of all double cars by logical decision, according to a criteria chain (KK), and subsidiarily by assignment of the double cars according to the minimal loss time of all involved passengers. The individual elevators each have a microcomputer system with a calculating device and are connected with each other by way of a comparator circuit to form a group control. The optimal individual cars are assigned for each elevator by floor in the associated individual car/call assignment memories. The optimal double car is selected by comparison of the loss times of all elevators calculated as the total operating costs Kg ( alpha ) and is assigned to the respective floor in the associated double car/call assignment memory. For the total servicing costs Kg ( alpha ), a special cost calculating algorithm is provided. With the separate assignment of individual cars and double cars, this group control renders possible a complete utilization of the double car functions as well as a good matching to different operating and traffic conditions. At the same time, the minimal waiting time of the passengers is optimized.

Abstract: The present invention comprises a first interconnect assembly and a second interconnect assembly which detachably connects to the first interconnect assembly. One of the interconnect assemblies includes a shutter for blocking an optical path. The first and second assemblies have surfaces which mechanically co-act to drive the shutter away from the optical path. An optical fiber is connected to one of these assemblies. In the preferred embodiment, the first assembly (13) forms a plug and the second assembly (15) forms an adapter, such as a socket. The socket assembly includes a shutter (183) which is spring-biased to a normally closed position. In this normally closed position, the shutter blocks passage of laser light to an optical fiber (79). The plug assembly includes an appendage (25) having a camming surface (73) which co-acts with a camming surface (142) on the socket assembly so as to drive the shutter to an open position which permits transmission of laser light to the optical fiber.

Abstract: The present invention relates to a novel method for forming metal matrix composite bodies and novel products produced by the method. Particularly, a permeable mass of filler material or a preform (1) has included therein at least some matrix metal powder. Moreover, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with the filler material or a preform (1), at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform (1). The presence of powdered matrix metal in the preform (1) or filler material reduces the relative volume fraction of filler material to matrix metal.
