Title: A method of applying an orthodontic aid
IPC: A61C7/14
Filed: 1989-02-10
Granted: 1992-12-23
Abstract: A method of applying an orthodontic wire which is affixed to at least one of a row of teeth with an adhesive. A cast is made of the row of teeth (2). The wire (4) is brought into the desired shape on the cast (1), and temporarily secured in position. Over the cast with wire, a layer of permanently resilient material is applied, which is deformed to conform to the shape of the cast to form a mould (6). The mould with the wire embedded therein is removed from the mould. The wire is temporarily removed from the mould, the mould is provided with perforations (5) at the desired locations, which correspond to the shape and dimensions of the adhesive receiving places, the wire is re-positioned in the mould, and the perforations are filled with adhesive. The mould with the wire embedded therein and adhesive applied is then placed on, and over, the row of teeth and pressed into contact with them. Any excess of adhesive pressed out of the perforations is removed, and the pressure is maintained until the adhesive has set on the row of teeth and secures the wire relatively to the row of teeth. The mould is then removed, leaving the wire affixed to the row of teeth.

Abstract: Porous shaped articles made from a molded composite of ultra high molecular weight polyethylene and polyethylene wax are disclosed. These articles are produced by free-sintering a non intensively mixed blend of UHMW-PE particles and particles of a polyethylene wax. The process involves mixing the UHMW-PE and wax both in powdered form until a heterogeneous mixture is formed, but under conditions which do not lead to any substantial fracturing of the UHMW-PE particles or melting of either component. The heterogeneous mix is then transferred to a press mold to form a shape and pressure is applied sufficient only to maintain the enclosed volume of the shape. The mold is heated to a temperature above the melting point of the UHMW-PE for a period of time to allow the particles to soften, expand, and contact one another at their surfaces. The mixture is then quickly cooled. Porous articles so produced may exhibit stiffness values in excess of about 2000 psi while at the same time showing excellent porosity values of less than about 25 inches water pressure drop.

Abstract: A programmable low voltage multi-band compression system suitable for use with hearing aids is described. Received audio signals are processed by a band split filter which separates the received audio signal into a plurality of frequency bands. A plurality of compressors coupled to the band split filter compresses each of the respective frequency bands. The output of the compressor are then summed to generate a composite audio signal. The compression ratio of each of the compressors is set, in response to a set of control signals, to a preselected independent value. The average gain of each of the compressors is set to a preselected level independently of the other compressors. In addition, the compression ratio of each compressor may vary with input signal level. Another set of control signals is employed for setting the gain of the compressor to provide a volume control function.

Granted: 1993-06-23
Abstract: Des agencements de l'enroulement de cryoaimants comprennent un enroulement en fil supraconducteur (12) connecté en parallèle à un enroulement en fil conducteur normal (11) qui, dans le cas d'une transition supraconductrice, transmet le courant de service et stabilise mécaniquement l'agencement d'enroulement. Indépendamment de cela, les dimensions d'un tel agencement d'enroulement dépendent avant tout des efforts de traction exercés sur les fils et du module d'élasticité du matériau dont se composent les fils. Comme les dimensions de ces agencements constituent un facteur significatif dans la détermination de leur coût, il est souhaitable de réduire leurs dimensions. Selon l'invention, l'agencement d'enroulement comprend dans la section de l'enroulement plusieurs groupes (17) agencés en couches qui se répètent dans le sens radial, de sorte que chaque spire de fil supraconducteur soit associée à une spire de fil conducteur normal et à une spire de fil d'acier ou d'un autre fil ayant un module d'élasticité élevé.

Title: Device for obtaining a load signal from a mechanically sprung and driven axle of running gear comprising a lift-axle
IPC: B62D61/12
Filed: 1990-04-30
Granted: 1992-11-11
Abstract: 2.1 The axle load of such a drive axle can be described by the spring deflection of the suspension spring and the pressure of the lifting bellows. A previously described device has a signal body which can be displaced axially by the pressure and rotated by the spring deflection. A three-dimensional characteristic diagram is arranged on the signal body and determines for each constellation of rotational position and axial position the insertion depth of the slide of an electrical displacement sensor into the stator and thus determines the axle load signal to be obtained. Because of the signal body with the three-dimensional characteristic diagram the known device constitutes a complex solution. 2.2 In order to simplify the known device, the present invention proposes the replacement of the three-dimensional characteristic diagram by a two-dimensional contour (20, 21) and a displacement capability of the stator (25) of the displacement sensor (24) as a function of the pressure of the lifting bellows (1). As a result, a pressure-dependent adjustment of the insertion depth is superimposed on the adjustment of the insertion depth of the slide (22) by the contour (20, 21). The preferred area of application is vehicle technology. <IMAGE>

Title: Handling method of destination calls registered in lift cars
IPC: B66B1/20
Filed: 1990-06-02
Granted: 1993-08-18
Abstract: An elevator group control with immediate allocation of floor calls includes an apparatus for processing car calls according to a car call algorithm implemented in a process computer in dependence on the traffic volume, the position of the calls, and the immediately allocated floor calls. Floor calls allocated by a floor call algorithm are entered for each elevataor car in a first list of the current one half round trip and/or in a second list of the next one half round trip. Both lists are stored in a memory region common to the algorithms. In the case of low traffic volume, car calls lying ahead of the elevator cars are entered into the first list unconditionally and car calls lying behind are entered into the second list subject to a maximum trip distance. In the case of average traffic volume, car calls lying ahead are entered into the first list in case synonymous allocated calls are already present therein. Otherwise, these calls are entered into the second list as also are the car calls lying behind subject to the maximum trip distance. In the case of high traffic volume, an entry takes place into the first and second lists only in case synonymous allocated calls are entered and the maximum trip distance is not exceeded.

Abstract: Method and apparatus for measuring displacement between layers of a semiconductor wafer wherein systematic errors associated with the measurement system are eliminated. An optical system, including a microscope and a camera, records an image of registration patterns on different layers of the wafer. The image is analyzed to measure displacement between the registration patterns. A first measurement is taken, the wafer is rotated by 180 DEG  about the measurement axis, and a second measurement is taken. The actual displacement between layers of the semiconductor wafer is calculated from the first and second measurements. Since the measured displacements change sign when the wafer is rotated and the systematic errors remain constant, systematic errors drop out of the calculated values of actual displacement. System errors can also be calculated for subsequent correction of measured values.

Abstract: Harmful constituents are removed from non-combustible solid waste, such as incinerator ash, by continuously feeding a mixture of the solid waste and a combustible excitation material into a reaction chamber, igniting the mix in said chamber and causing it to react in the presence of oxygen until the heat of the reaction causes the solid waste material to become a molten slag and the temperature within the chamber above the molten slag is high enough to destroy substantially all of the harmful constituents in the gaseous effluent released by the formation of the molten slag. The excess molten slag is conducted from the reaction chamber. The effluent is conducted from the reaction chamber into a second chamber where it is rapidly cooled to cause particulate material to precipitate out of the effluent. The effluent is thereafter treated to remove substantially all of the remaining particulate and harmful gases to achieve acceptable environmental quality. The thus treated effluent is released into the atmosphere.

A partitionable section of the array containing several processing units are contained on a silicon chip arranged with "Picket"s, an element of the processing array preferably consisting of combined processing element with a local memory for processing bit parallel bytes of information in a clock cycle. A Picket Processor system (or Subsystem) comprises an array of pickets, a communication network, an I/O system, and a SIMD controller consisting of a microprocessor, a canned routine processor, and a microcontroller that runs the array. The Picket Architecture for SIMD includes set associative processing, parallel numerically intensive processing, with physical array processing similar to image processing. a military picket line analogy fits quite well. Pickets, having a bit parallel processing element, with local memory coupled to the processing element for the parallel processing of information in an associative way where each picket is adapted to perform one element of the associative process. We have provided a way for horizontal association with each picket. The memory of the picket units is arranged in an array. The array of pickets thus arranged comprises a set associative memory. The set associative parallel processing system on a single chip permits a smaller set of `data' out of a larger set to be brought out of memory where an associative operation can be performed on it. This associative operation, typically an exact compare, is performed on the whole set of data in parallel, utilizing the Picket's memory and execution unit. <IMAGE>
