Title: Sealing for valves or flanges, especially for vacuum application
Inventor: BOSCH HUBERT
IPC: F16L23/16
Filed: 1989-10-12
Abstract: In a sealing for valves or flanges which is used especially for vacuum application, two mutually opposite sealing surfaces are arranged on a main flange, on which sealing surfaces a sealing element in the form of a disc spring which is adjustable in the axial direction can be brought to bear. 
<??>In order to be able to make do with a smaller closing force, the disc spring is arranged in the gap between an axially adjustable ring of smaller diameter and a plate of larger diameter. The plate can be elastically deformed radially outwards and inwards and the radial length of the disc spring is chosen such that when the sealing is open the disc spring is tilted in the gap and when the sealing is closed it bears on the main flange approximately parallel on a radius line with the sealing seat.

IPC: G21C17/032

Abstract: A boiling water reactor includes a pressure vessel having internal forced circulation through the core. An annular downcomer region establishes reactor coolant flow downwardly in the periphery of the reactor vessel and finally upwardly and centrally into the core across a core plate (30). A pressure sensor (32,34) detecting the pressure differential across the core plate is utilized. This pressure sensor has its measurement enhanced by input from local power range monitors (42,44,46,48,50,53,54,56) in the core to utilize both the sensed pressure differential and the power to predict more accurately flow in the reactor. An algorithm utilizes the pressure differential and the real time readings from the local power range monitor to accurately gauge overall reactor coolant flow. To ensure accurate calibration, two calibration standards are utilized at steady states of reactor power output and coolant flow. A first calibration standard includes the installation of thermocouples adjacent the reactor core plate for measurement of fluid enthalpy of the coolant as it flows upwardly through the reactor core. The determined enthalpy is utilized in an energy flow balance wherein the core flow rate is solved for as an unknown. A second calibration standard utilizes the sensed pressure differential across the annular pump deck of the forced circulation pumps. The two standards are combined in output utilizing a least squares averaging, and the result combined to calibrate the algorithm.

Abstract: The apparatus employs a magnetic head which has a non-magnetic gap member (3) disposed in a magnetic body (1, 2) with positive magnetostriction constant. During reading of data from a recording medium by a coil (4) wound around the magnetic body, a dc bias magnetic field is caused to be generated in the magnetic body. This field causes a magnetostriction effect in the magnetic body which compresses the gap member thereby cancelling the tensile stress generated by the expansion rate difference between gap member and magnetic body.

Inventor: ROTTINGHAUS ALAN PATRICK
IPC: H03C3/00
Filed: 1991-01-30
Abstract: In a fast-switching frequency synthesizer switching between receiving and transmitting mode frequency is done by changing the divisor of the loop divider and by presteering voltage injection at the voltage controlled oscillator ("VCO") with feedback to allow the VCO, and synthesizer, to quickly transition between two given frequencies. This presteering mechanism, with the feedback, allows the presteering voltage to track the variations in the VCO gain from device to device, and gain changes while in operation. This same information is used to implement a means of automatically adjusting the FM deviation of the transmitter since that information varies with the gain of the VCO as does the FM deviation.

Abstract: A method and apparatus for performing the majority of texture map gradient calculations once per polygon so as to increase processing speed in a graphics system. Texture values are identified for each vertex of an input polygon and are interpolated over the polygon in perspective space in order to find the corresponding values at a given pixel within the polygon. The perspective values of the vertices are linearly interpolated across the polygon to determine the value at the given pixel. The texture gradients are then calculated by defining vectors perpendicular and parallel to the horizon of the plane containing the input polygon so that the resulting components may be calculated. The resulting value is the texture gradient, which may then be used to address a texture map to determine the pre-filtered texture value for that point. A hardware implementation is disclosed whereby the necessary calculations are done in hardware for each pixel in the input polygon. The invention so arranged removes artifacts in the texture mapped image at a low cost and high speed.

Abstract: The breakdown voltage of a MOSFET transistor is increased by reducing the electric field at the gate edge and/or at the field oxide edge. The electric field is reduced by moving the N + source/drain implant away from the gate or field edge by altering the geometry of the N + source/drain implant mask already used in the process. Diffusion continuity to the gate and field edges is maintained by a N- implant. A MOSFET transistor device having enhanced high voltage characteristics includes heavily doped source and drain regions spaced apart from both the gate edge and the field oxide edge. Lightly doped regions contiguous with the heavily doped source and drain regions extend from the edges of the heavily doped regions to both the gate and the field oxide edges. Another MOSFET transistor device having enhanced high voltage characteristics includes heavily doped source and drain regions spaced apart from the gate edge. Lightly doped regions contiguous with the heavily doped source and drain regions extend from the edges of the heavily doped regions to the gate edges.

wherein A is an initiator moiety derived from an active hydrogen-containing initiator having at least 1 carbon active hydrogen, IB is a hydrophilic polyoxyalkylene inner block having a molar ratio of less than oxygen 2.5, OB is a lipophilic polyoxyalkylene outer block having an ester linkage to
     carbon

Abstract: An elevator dispatching system is provided so that floors of a building are assigned to non-overlapping, equal traffic volume sectors that are dynamic in that both the number of floors in the sectors and the number of sectors is variable, depending upon traffic predictions for an up-peak period in the building. The floors within a sector are contiguous and the sectors within the building are contiguous. After the sectors are created an elevator car is assigned to each sector to be dispatched in association therewith. A floor service indicator means displays which elevator cars have been assigned to which sectors. 
     Where the sum of the populations of adjacent sectors falls below 100% of car capacity, said sectors are combined. 
     When the sum of the populations of adjacent sectors does not exceed a given limit, the adjacent sectors are combined and the elevator cars are dispatched according to the new sector assignments.
