Title: Automative machine for arranging bricks
Inventor: CHI WU CHING
IPC: B65G47/90
Filed: 1986-05-12
Abstract: The machine comprises clamps 4 mounted on an elevator 3 movable vertically by hydraulic cylinder 52 acting on pulleys 231 of a 4 steel cable and pulley system, and movable horizontally on wheels 22 by a further hydraulic piston 51. Each clamp 4, Figure 6, is rotatable about a vertical rod 41 by the action of a worm 91 slidable along and rotated by a keyed shaft 9, the worm acting on a worm gear 46 to cause the rotation, the clamping members being pivoted about ball shaped ends 441 for the clamping action by vertical movement of rod 41. The bricks of one layer can be arranged at an angle to the bricks of another layer. The distance between the clamps 4 can also be varied. <IMAGE>
Patent GB-2191880-A (GB)
Title: Linear interpolation
Inventor: FORT ANDREW JEFFREY
IPC: G06F17/17
Filed: 1986-06-13
Abstract: A digital linear interpolator has a main read-only memory 81 which both drives, and receives addresses from, a microsequencer 80 once a starting signal MINT* has been received. By means of an address counter 24 the memory 81 addresses an active memory containing tables of given values of dependent variables and of the independent variables related thereto. When a further value of an independent variable is loaded into the active memory, a main processor 16, which includes the memory 81, searches for a given value of independent variable close to the further value, and computes from the address of this given value and possible other given values the address of a related given value of the dependent variable. A concurrently operating subsidiary processor 17 uses the previous related given value thus found, and other data, in a linear interpolation equation to calculate the value of the dependent variable corresponding to the further value of the independent variable. The main processor 16 includes a floating point ALU 18 for computing differences between the further values and close given values of independent variables. The subsidiary processor 17 includes a floating point ALU 92 for computing differences and sums and a floating point multiplier 93 for computing products included in linear interpolation equations. <IMAGE>

Title: Bar coating apparatus
Inventor: SHEPHERD JOHN VICTOR
IPC: B05C11/04
Filed: 1987-01-07
Abstract: Simple bar coating apparatus is described. A sheet of material (3) to be coated is laid on a coating bed and the bar (1) is traversed across it. A bead of liquid between the bar and the sheet to be coated is moved across the sheet so that the liquid deposits as a coating. In accordance with the invention, at the same time as the bar is moved across the sheet, it is rotated about its axis but at a peripheral rotational speed less than that of its translational speed across the coating bed. Various mechanisms may be employed to cause the relatively slow rotation, which is preferably 1 to 35% of the translational speed. <IMAGE>

Title: Apparatus for precipitating exhausted smoke from a chimney
Inventor: HUANG CHIEN-FENG
IPC: F23J15/02
Filed: 1987-03-12
Abstract: An apparatus for treating the exhausted smoked from a chimney by precipitation has a smoke collecting device placed at the exhaust of the chimney and a vapour injecting nozzle to spray high speed vapour over the smoke from the chimney into the collecting device. A water tank for receiving the mixture of the vapour and the smoke and precipitating the same with the water contained therein is connected to the collecting device by a conduit. The conduit is provided with suction means to accelerate the flow of the mixture of the vapour and the smoke to the tank. The water tank may also be equipped with set of vapour spraying devices and a smoke filtering web for preventing the possible leakage of smoke from the water tank. A preferred embodiment has two opposing collecting devices, each provided with its own conduit, suction means, and tank.

Patent GB-2190309-A (GB)
Title: Spray devices
Inventor: BUDDEN HARRY GEORGE EDWIN
IPC: B05B14/00
Filed: 1987-05-08
Abstract: A spray device for spraying glazes slurries or emulsions used in the food industry has a spindle 12 and a disc 10 which are rotated. Fluid to be sprayed is passed through a feeder tube 24 to impinge on the conical valve member 30. When the fluid flow rate is considerable, the valve member 30 deflects the flow outwardly and the fluid then hits the diffuser plate 34 and is deflected outwardly towards the surface 38 of the disc 54. When the fluid hits the disc it is caused to move outwardly as a result of the centrifugal force exerted by the spinning disc. The fluid then travels over the surface 38 until it leaves the periphery 40 of the disc and is thrown outwardly. At a lower fluid flow rate, the fluid passes directly from the valve member to the surface 38. <IMAGE>

Title: Floating gate synapse cell with dual control gates
Inventor: TAM SIMON M
IPC: H01L27/115
Filed: 1990-05-29
Abstract: A synapse cell in a neural network comprises a floating gate transistor 72 having a dual control gate structure 78, 79. Charge stored on the floating gate corresponds to the weight of a neural connection between input line 85, 91 and output summing line 87, with which an input pulse, having a fixed amplitude and applied to both input lines but a variable duration, is multiplied to discharge the output summing line 87. Programming or erasing of the weight stored on the floating gate is achieved by raising both control gates 78, 79 to a programming or erase potential with suitable potentials applied to the source and drain of transistor 72. Because of the dual control gate structure, disturbance of adjacent synapse cells 70, 73 in a "half-selection" mode is virtually eliminated. <IMAGE>
