Title: Network and method for interconnecting router elements within parallel computer system
Inventor: TAYLOR STUART A
IPC: G06F13/40
Filed: 1991-01-04
Abstract: A network and method for interconnecting a plurality of router elements (11-13, 20-23, 30-33) in a parallel computer. The network forms a routing system (5) for routing data from source processing elements (PE1 - PE64) to destination processing elements. The input lines (IL-101 to IL-116) and output lines (1A1 to 1D4) of each router chip (100) are prioritized. Higher priority output lines (2A1, 2A2) from a given output group (A) of a first routing element (10) are connected to low priority input lines (415, 410) of a second routing element (20) and lower priority output lines (2A3, 2A4) from the output group (A) of the first routing element (10) are connected to higher priority input lines (401, 408) of the second routing element (20).

Title: Imager having improved thin film transistor and photosensitive device structures
Inventor: KWASNICK ROBERT F
IPC: H01L27/146
Filed: 1991-08-08
Abstract: RD-19,885 AN IMAGER HAVING IMPROVED THIN FILM TRANSISTOR AND PHOTOSENSITIVE DEVICE               STRUCTURES           Abstract of the Disclosure An improved structure for a thin film transistor photodiode photosensitive array retains the semiconductor material of the thin film transistor layer under the entire area occupied by the photosensitive device for each pixel of the array.  This eliminates a step in the layer on which the source metallization of the thin film transistor is disposed and results in more reliable passivation of that layer and thereby increases yield and reduces cost.  Several improved processes may be employed for the fabrication of such a thin film transistor photodiode photosensitive array.

Inventor: KOEHLER RANDAL W
IPC: G05G1/08
Filed: 1991-08-29
Abstract: 90 CON 274(AP) ABSTRACT     A rotary actuator for an appliance control system, such as a gaseous fuel burner ignition system, having a shaft means thereon locked in an "OFF" position between a stop and a detent which requires the user to move (push) the shaft axially in order to enable the cam means to clear the detent to permit rotary movement away from the "OFF" position stop for affecting a control function such as a burner ignitor.  As the cam means is rotated past the detent to the desired "ON" position, and upon user release, the shaft is spring biased to its initial axial position.  Upon return rotary movement of the shaft by the user, the cam means automatically moves the shaft axially to enable the cam means to pass by the detent to return to the "OFF" position against the stop.

IPC: B21D7/024
Filed: 1991-11-25
Abstract: CURVED GRID TEES FOR SUSPENSION CEILINGS                 ABSTRACT OF THE DISCLOSURE           A horizontally  curved  grid  tee  for  suspension ceilings is bent in the direction parallel to the plane of the flanges of the grid tee.  Such grid tee is provided with end connectors and openings so that the grid tee can be assembled in a suspension ceiling grid combining curved grid tees and/or straight grid tees to produce aesthetically pleasing patterns.  When panels are installed in the openings defined by the curved grid tees, appropriate mating curves are formed in the panels so that the panels are supported at their periphery.  A method and apparatus for producing such grid tees involves curved tooling which cooperates to confine a straight grid tee as it is bent to the curved shape.  The tooling provides grooves  into which the flanges project during the bending operation.  Such grooves are constructed and dimensioned so that the inner portion of the flange which is subjected to compressive stresses is not buckled.  Such tooling allows the production of curved grid tees having a planar smooth flange in which the exposed surface coating applied as a prepainting operation is not damaged.

The tube is precisely immovably secured in both orientation and elevation to the deck by an external circumferential rib (38) bearing against the upper surface of the deck, and one or more staking protrusions (40) that bear against the lower surface of the deck. The tube is made from a flat blank of sheet material (59) which has a first pair of opposed edges provided with locking tabs (61) a second pair of opposed edges that eventually form the top and bottom ends of the tube, and a rib (38) that is generally perpendicular to the first pair of opposed edges. The blank is deformed to form a tube (24) in which the locking tabs (61) engage each other and the rib (38) is positioned externally and circumferentially. The tube is inserted in a deck opening until the rib (38) engages the upper surface of the deck (20), and the tube is locked in its precise final position by protrusions (40) that engage the lower surface of the deck. The tubes are field-replaceable.

IPC: F01D17/18
Filed: 1992-10-06
Abstract: 56,877 ABSTRACT OF THE DISCLOSURE A method for improving operational efficiency of a partial-arc steam turbine power plant during power output variations by dynamically adjusting valve point values during turbine operation.   Impulse chamber pressure at each of a plurality of valve points is first determined during operation of the steam turbine at constant pressure.  For each adjacent pair of valve points, an optimum constant pressure transition point pressure for transitioning from one to the other of the sliding pressure mode and constant pressure mode is then computed.   The optimum constant pressure transition point pressure for each pair of valve points is converted to a corresponding percentage of the pressure difference between the adjacent pairs of valve points.  The impulse chamber pressure at each valve point is then used to calculate a corresponding impulse chamber pressure for transitioning from the one mode to the other mode based upon the percentage pressure difference.  The calculated impulse chamber pressures for transitioning are compared to measured values of impulse chamber pressure and the system force transition from one of the modes to the other mode when the measured value is substantially equal to the calculated transition pressure.
