Title: Fluid pump automatic shut-off control device
Inventor: CHANG TSAI-FU
IPC: F04B49/02
Filed: 1991-01-11
Abstract: A fluid pump shut down device, preferably for use in a water supply system, includes a housing (21, 22) having a chamber with inlet (23) and outlet (231) ports. A magnetic valve (24) is located within the chamber and is controlled by a bias spring (25) to prevent water flow when water is not being pumped through the supply system. The magnetic valve is moved away from the closed position when water from a water source is pumped by the water pump into the water inlet port (23). The movement of the magnetic valve controls a normally open switch (26) to close the contacts (261) of the switch when the magnetic valve is closed and to energise a heat emitting resistor (27) which in turn heats a bimetal thermostat (28) to deform the contacts thereof, when the water supply is stopped from entering the water inlet port eg when the source is depleted. Opening the contacts of the thermostat disconnects the power supply to the pump. <IMAGE>

Title: Adjustable nozzle for hypersonic engine combustion chamber
Inventor: KRETSCHMER JOACHIM
IPC: F02K1/08
Filed: 1991-03-21
Abstract: In a ram jet combustion chamber having fuel injectors 34 and an exhaust nozzle 7, the nozzle throat cross-section (between the widest part of a displacement body 15 and an outer wall 10 increases along with increase in combustion space length as the body 15 axially slid able on a support pipe 18 is moved outwards, and conversely, both parameters decrease as the body (15) is moved inwards. This interdependence results in highly effective ram-jet operation. In other embodiments, air may be delivered to the ram jet combustion chamber by a double pipe (figs 2 to 5) or may serve as a combined ram-jet combustion chamber and afterburner chamber of turbo engine (figs 6 and 7) which may have a bypass arrangement. <IMAGE>

Title: "screen"
Inventor: TIDMARSH THOMAS JOHN SCOTT
IPC: E05G7/00
Filed: 1992-06-11
Abstract: A screening device (1) for use in banks or building societies is provided where a flexible screen (7) can be moved across a window (5) which is located above a counter (4) to obscure the view through the window (5) and thereby break visual contact between the cashier on one side of the window (5) and a gunman on the other side of the window (5). The movement of the flexible screen is rapid and is triggered by the provision of an electrical alarm signal. The leading edge of the screen (7) is provided with a rail (11), itself having a leading edge covered with a strip of padding (13) to prevent injury to a cashier's hand if positioned below the rail (11). The rail (11) is made heavy so that it descends under the force of gravity. The screen is dispensed from a first roller (9) which is biased to wind the screen (7) onto itself but the biasing force of the roller (9) is less than the force exerted on the rail (11) by gravity so that on activation of a release mechanism the rail (11) and screen (7) descend rapidly down across the window.

Title: Walker having retrofit wheels and brakes
Inventor: CASS TERENCE JAMES
IPC: A61H3/04
Filed: 1992-10-12
Abstract: The invention provides a kit for converting a conventional unwheeled walker 10 into a walker having wheels and brakes. Hand brakes of the type used with bicycles are releasably clamped to the handles 20, 22 of the walker. Cables 40, 60 extend from each hand brake to a brake assembly of the type used in bicycles. Each brake assembly includes a pair of brake pads 34/36, 48/50 positioned on opposite sides of their associated caster wheels 30, 50. The pads frictionally engage the wheels when the brake handles 38, 58 are squeezed so that the wheels cannot rotate. To carry out the conversion, the caps are removed from the lowermost end of each walker leg 12, 14, 16, 18 and the stems 70 of the caster wheels 30, 50 are inserted into the hollow interiors of the legs. Each stem 70 has diametrically extending throughbores formed in it. The legs are provided with vertically spaced diametrically extending throughbores 72 as well, and pins extend through aligned throughbores to vertically adjust the height of the walker. A tray 66 is releasably attachable to the walker 10 in a stored position, a seat-providing position, or a tray-providing position. <IMAGE>
Patent GB-2269081-A (GB)
Title: Image processing apparatus
Inventor: MURATA MASAHIRO
IPC: G06T15/40
Filed: 1993-07-23
Abstract: An image processing apparatus for use in three-dimensional graphics has a frame buffer for storing image information and depth information per pixel. For high-speed pattern filling, the frame buffer has an image buffer (34) for simultaneously storing image information of a predetermined number of pixels arranged in a horizontal direction in response to write permit signals individually given to the pixels, respectively, a Z buffer (31) for simultaneously outputting stored depth information relative to the pixels and simultaneously storing new depth information with respect to the pixels in response to the write permit signals. An identifying circuit identifies whether a condition indicating that an image to be plotted is a horizontal line is satisfied or not. As many write permit signal output circuits as the predetermined number simultaneously calculate respective items of new depth information relative to the pixels when the condition is satisfied, compare the depth information read from the Z buffer (31) with the calculated depth information, and simultaneously output the write permit signals relative to the respective pixels to the image buffer (34) and the Z buffer based on the result of comparison. Such an image processing apparatus can calculate Z values at high speed when plotting a horizontal line to achieve high-speed plotting operation. For Z merging, another image processing apparatus has an image buffer for storing image information per pixel and outputting the stored image information, and a Z buffer for storing depth information per pixel and outputting the stored depth information. <IMAGE>

Title: Data processor with both static and dynamic branch prediction, and method of operation
Inventor: ROSSBACH PAUL C
IPC: G06F9/38
Filed: 1994-10-10
Abstract: A data processor (10) (Fig.1) has branch prediction circuitry 62 - 76 to predict a conditional branch instruction address before the condition on which the instruction is based is known. The branch prediction circuitry operates in one of two user selectable modes: dynamic branch prediction or static branch prediction. In the dynamic mode, the prediction is based upon a branch state history maintained at 62 for each branch instruction. Each branch state may be updated after the data processor determines if the prediction was correct. In the static mode, the branch prediction is based on one or more bits embedded in the branch instruction. The data processor may or may not update the branch state of each branch instruction during this second mode, as desired by the user. In either mode the predicted address is selected from the output of an incrementer 72 or a calculator 74, by a multiplexer 68. <IMAGE>
