Title: Metal recovery
Inventor: WHYTE RODNEY MURISON
IPC: B01D15/02
Filed: 1989-03-13
Abstract: The invention provides an installation for recovering metal values from a pulp or leach solution by carbon-in-pulp or resin-in-pulp adsorption, comprising a number of adsorption cells. Each cell comprises a container having an inlet and an outlet, a screen disposed between the inlet and the outlet, and an impeller adapted to force liquid entering the container via the inlet through the screen and out of the outlet. The installation includes a conduit for feeding a metal-laden pulp or leach solution to each adsorption cell selectively. The supply of the pulp or leach solution to a selected cell can be interrupted for removal of metal-laden carbon or resin from the cell. The same conduit returns the loan pulp or leach solution from each cell to a further adsorption cell.

Title: Magnetohydrodynamic propulsion arrangements for marine vessels
Inventor: CHURCH PETER DUDLEY
IPC: B63H11/02
Filed: 1989-03-17
Abstract: An MHD (magnetohydrodynamic) propulsion arrangement for ships or other marine vessels, in which the magnetic field is trapped in a closed path (B) by solenoids (51) and, optionally, magnetic shunts (52). The interacting current (I) is then passed radially through this path between electrodes (43, 55) at least the outer one of which (55) extends around a major part of the magnetic path (B). The flux and current paths are then oriented, by virtue of their mounting on the ship, to produce a force along the ship axis. A highly efficient high speed propulsion system can thus be produced.

Title: Processor for recursive computations
Inventor: KNOWLES SIMON CHRISTIAN
IPC: G06F7/544
Filed: 1989-06-13
Abstract: A processor suitable for recursive computations incorporates multiplier cells (16) connected to form rows (12) and columns (14). Each row (12) is arranged to multiply by a coefficient. It begins with accumulator cells (18 and 20), and continues with multiplier cells (16) arranged to multiply by individual coefficient digits and disposed in descending order of digit significance. Columns (14) other than the first column (141) begin with a multiplier cell (16), and the higher significance columns (141 to 144) terminate at respective accumulator cells (20). Any intervening multiplier cells (16) are arranged in ascending order of multiplier digit significance. The multiplier and accumulator cells (16 to 20) operate in accordance with signed digit number representation arithmetic involving digit redundancy. They generate sum and transfer digits for output down columns (14) and along rows (12) respectively to neighbouring cells, in the direction of increasing digit significance in the case of transfer digits. The cell arithmetic employed makes it possible to compute results most significant digit first. Each result digit is recycled when formed to provide a multiplicand digit input for all multiplier cells (16) of a respective row (12) selected in accordance with result digit significance. The processor (10) is also arranged to add successive non-recursive input terms to multiplier products. This provides for the processor (10) to provide a first order infinite impulse response (IIR) filter section, and two cascaded processors (50, 50') provide a second order IIR filter section. <IMAGE>

Title: Method and apparatus for conditioning an electronic component having a characteristic subject to variation with temperature
Inventor: PICKERING JOHN ROBERT
IPC: H01L27/02
Filed: 1991-07-31
Abstract: An electronic component 1 is conditioned to remove distortion in a temperature response characteristic due to a temperature hysteresis effect, by subjecting the component to a controlled temperature variation prior to operation of the component at a given temperature. A bias voltage of cyclical waveform and of reducing magnitude is applied to a transistor 3 to cause corresponding variation of the temperature of the component 1 via an on-chip heater 4. The transistor 3 is subsequently operated at a normal bias voltage corresponding to the mean value of the cyclic waveform. A circuit for generating the cyclic waveform is described (Fig 3). <IMAGE>

Title: Riser tensioner system for use on offshore platforms using elastomeric pads or helical metal compression springs
Inventor: ARLT EDWARD J
IPC: E21B19/00
Filed: 1991-08-30
Abstract: A riser tensioner system 10 is provided for use on offshore oil drilling platforms to support a riser 12 relative to a floating platform. The riser tensioner system 10 uses either elastomeric pads 32 or helical metal springs as an energy absorbing medium, rather than hydraulic, or pneumatic systems. The elastomeric pads 32 or helical metal springs are maintained in compression within a shock absorber housing 26 by a plunger 30 which is compressed by the weight of the riser 12. If the riser tensioner system 10 is arranged to place the shock absorber 20 in tension, the shock absorber plunger 30 is inverted in the housing 26 to maintain the elastomeric pads 32 or helical metal springs in compression. To achieve varied response characteristics, nested inner and outer elastomeric pads or compression springs are arranged to act together. A varied response characteristic may also be obtained by varying the elastomeric pad modulus or the helical spring constant, or by use of conically shaped elastomeric pads. <IMAGE>

Filed: 1992-11-17
Abstract: In a pitch control system in which generation of tremolo sound is suppressed, a common clock (11) is used for both write timing and read timing of a ring buffer (3). The data representing samples of analogue waveforms, are interpolated (2) before writing to a memory of the ring buffer (3), a plurality of write positions (Wn, Wn-1) are provided and the data is written while controlling addresses so that addresses are not left empty when raising the pitch or supplied with plural samples when lowering the pitch. Address spacings between a plurality of read memory positions (Ra, Rb, Rc) are different from each other. Coefficients are set within a range from a predetermined negative value to a predetermined positive value according to address spacing in order to write memory position for each of the read memory positions, and the data read from each of a plurality of read memory positions are multiplied by the corresponding coefficient. The resultant data values are summed up and are used as output data. Further, a comb line filter may be provided in the signal path. <IMAGE>

Title: Non-impact printer for printing a video signal of higher resolution
Inventor: TANUMA JIRO
IPC: H04N1/036
Filed: 1993-06-22
Abstract: When a video signal (11) received at a printing control unit (1) has a higher resolution than an LED head (19), the control unit (1) carries out a logical AND operation between successive bit data of the video signal (11) to convert the video signal (11) to a first signal. Corresponding to a line timing signal, this first signal is transferred as a head data signal (18) to the LED head (19) and is then printed on a basic raster scanning line. Further, the control unit (1) also carries out an exclusive-OR operation between the successive bit data of the video signal (11) so that the video signal (11) is converted to a second signal and outputted to a line buffer. Corresponding to an additional line timing signal, the second signal is transferred as another head data signal (18) to the LED head (19) and is printed on an additional raster scanning line. The LED head drive energy for performing printing along the two raster scanning lines is set independently; that of the additional raster scaning line may be lower. <IMAGE>

Title: A method for manufacturing a thin-film el device
Inventor: KATOU HISATO
IPC: H05B33/18
Filed: 1993-09-21
Abstract: A light-emitting layer 4 of a thin-film EL device is formed using a sputtering process so that the light-emitting layer is composed of ZnS that contains the optimum concentration of Mn as the light-emitting core. With the understanding that the Mn concentration in a light-emitting layer formed using a sputtering process becomes higher than the Mn concentration in a target, a ZnS:MnS target with the Mn concentration that is lower than the optimum concentration is used. Otherwise, the Mn concentration on the target surface is adjusted according to the ratio of the Mn area exposed on the target surface to the ZnS area. Such a target may be a mosaic target or a target with Mn pellets placed on a ZnS substrate. Furthermore, the Mn concentration in the formed light-emitting layer may be controlled by using a ZnS target and a ZnS:MnS target and adjusting the ratio of the discharge power supplied to each target. <IMAGE>
