Patent GB-2176207-A (GB)
Title: Metal recovery
Inventor: CHADWICK DR ANDREW THOMAS
IPC: C01G53/00
Filed: 1985-06-04
Abstract: In the recovery of metal, such as a non-ferrous metal, from an aqueous solution thereof by extracting the metal into an organic solvent phase, back extracting the metal into an aqueous phase therefor, and plating out the metal electrolytically, the back extraction and plating out are both carried out in the cathode compartment of an electrochemical cell, e.g. in a rotating cathode contactor. This procedure reduces the number of process operations, improves process effectiveness and gives the metal in a form (e.g. powder) suitable for subsequent removal and processing.

Title: Sensing electrical contact with underwater structures
Inventor: BACKHOUSE GEOFFREY HOWARD
IPC: G01R31/50
Filed: 1986-06-12
Abstract: Apparatus for sensing when a probe (106) is in proper electrical contact with an underwater metal structure (not shown) comprises two open loops (108, 110) terminated by electrodes (102, 104, 106) that are in electrical contact with the water. The loops are energised by a pulse source (120) and a detector arrangement (128-140) responds to the current differential in the loops preferably by using peak detectors (134, 136). The loop currents are normally in balance but contact of the probe (106) with a submerged metal structure causes an unbalance which can be used to signal that a proper contact has been made. The apparatus may be used in other conductive media, not necessarily fluids. <IMAGE>

IPC: H02P1/26
Filed: 1988-09-26
Abstract: A three-phase motor 10 has a relatively large 'starting' capacitor 20 connected in parallel with a smaller 'running' capacitor 18 via a switch 22, which allows the 'starting' capacitor to be decoupled from windings 12a, 12b, 12c, of the motor, which are connected to a single-phase supply. The capacitor 20 provides an energy storage device whereby energy is stored from the single phase supply and is delivered to the windings 12a, 12b, 12c at the required instants. Further embodiments are described (Fig 2 & 3) where the windings are connected in star connection. To stop the motor switch 15 is opened and start switch 22 is closed so that capacitor 20 and resistor 24 are connected across the motor to enhance braking. <IMAGE>

Title: A Signal Equalising Arrangement and a Method of Equalising a Received Data Signal
Inventor: GURCAN MUSTAFA KUBILAY
IPC: H04B7/005
Filed: 1988-10-05
Abstract: A signal equalising arrangement comprises a decision feedback equaliser formed by a feedforward filter section 16 connected to a feedback filter section 18 which includes a decision stage 20. If the performance of the equalising arrangement as determined by the signal to noise ratio versus the bit error rate is found to be below the calculated optimum performance of the decision feedback equaliser, then an improved performance may be obtained by operating the equaliser in a time reverse mode. In order to operate the equaliser in a time reverse mode, a first last-in, first-out store 60 is connected in the signal path to the feedforward filter section 16 and a second last-in, first-out store 62 is connected to the output of the decision stage 20. For working with the last sample of the impulse response, the feedforward section may be omitted (Fig 6). <IMAGE>

Title: Semiconductor device and production method therefor
Inventor: KOBIKI MICHIHIRO
IPC: H01L21/301
Filed: 1989-06-29
Abstract: A semiconductor device, eg a high power FET device 101, includes a metallic layer 7a extending from a rear surface to a front surface to protect device side walls during handling. During fabrication a separation groove 13 is spaced outwardly from the device on a wafer and contains a metallic layer which becomes the side wall protection after dicing the device from the wafer. The side wall protection layer 7a extends onto portions of the front surface of the device as a measurement electrode. A via-hole 9 extends through the substrate connecting a rear surface electrode to the front surface. The arrangement gives access to the source, drain, and gate electrodes of the device from the front surface for measuring the electrical characteristics of the device while it is still part of a wafer containing a large number of devices. Preferably, the separation grooves 13 are wider and deeper than the via-holes 9. The devices are made by etching the separation grooves and the via-holes from the front surface of a substrate. Thereafter, the thickness of the substrate is reduced from the rear surface. <IMAGE>
