Title: Semiconductor switch with overtemperature protection
Inventor: MARSHALL ANDREW
IPC: H01L29/732
Filed: 1990-05-29
Abstract: A semiconductor switch contains a power bipolar switch element (T1) for control of the energisation of a load or a bridge of such elements. The switch elements, which may be transistors or darlington multiple transistors, have voltage dropping means (R1) connected in the leads to their control bases, which voltage dropping means may be a series resistor (R1) or a constant current circuit. The switch has temperature sensitive means, such as a diode (D1), for diverting current from the control base of the or each switching element to terminate its conduction if the temperature of the element becomes too high.

Patent GB-2233668-A (GB)
Title: Recovering heavy metal compounds
Inventor: URQUHART WILLIAM MCDONALD
IPC: F23C3/00
Filed: 1990-06-12
Abstract: Heavy metal compounds, particularly vanadium and nickel compounds are recovered from petroleum coke by combusting the coke under conditions constraining the temperatures to within the range 600 to 1400 DEG C, collecting the ash which is then subjected to a known process for the extraction of the metallic compounds. Whilst the combustion process may be achieved in a fluidised bed furnace, high recovery rates are likely to be achieved utilising a tubular furnace chamber 2 inclined at 10 DEG  to horizontal. Dried petroleum coke, ground to fine powder (ASTM 75 micron, or less) is entrained into a primary air flow injected tangentially into the chamber through ports 18, 20, 22, 24 together with secondary air sufficient to maintain an oxidising atmosphere. Molten slag is deposited on the chamber wall by centrifugal action and drained from the chamber to fall on a rotating steel drum immersed in a water trough. A scraper removes the slag from the drum as flakes which are removed from the water trough using a screw conveyor.

Title: Cross-linked antibodies and processes for their preparation
Inventor: RHIND STEPHEN KEITH
IPC: C07K16/00
Filed: 1990-10-09
Abstract: Cross-linked antibody conjugates are described which have at least one interchain bridge containing a reporter or effector molecule.

Title: Spray painting using a mask and a shielding air flow
Inventor: POLLOCK THOMAS MUNN
IPC: B05B15/04
Filed: 1991-09-20
Abstract: A method of spray painting an article, such as a housing for electronic equipment, having areas which need to be masked-off comprises fitting a mask (6) such that a spacing (2) is left between the periphery of the mask and the edge of the area to be masked-off, and passing a flow of air (A) through the spacing counter to the direction of paint spraying (S) to prevent entry of the paint into the spacing. The mask may be in the form of a pin-type protrusion (6) for masking the inside wall (14) of an aperture, or in the form of a cover (see dotted lines, figure 3) placed over the masked-off area (e.g. an area of the electrical circuit boards 22 & 28, figure 3). The problem of providing a close-fit around the masked area is alleviated. <IMAGE>

Title: Power reducing circuit for A.C. Load
Inventor: BALLANTYNE STEPHEN LESLIE
IPC: H02P25/14
Filed: 1992-08-05
Abstract: The purpose of the invention is the provision of a load modification arrangement in an electrical circuit with the objects of saving energy and of prolonging the working life of the load device 10 for example a lamp or a motor. A triac 14, which is triggered by a diac 16 and a fixed phase shift circuit 18, causes the load to operate at a fixed proportion of its nominal rated power, eg. 60 to 90% and particularly 75%. In order to avoid the problem of say feedback current causing the triac current to fall below its holding level so that the triac 14 switches off prematurely in each AC half cycle, the triac 14 may have a slow dv/dt capability thereby giving it poor turn-off characteristics. The trigger circuit may also be modified to incorporate a holding current arrangement adequate to overcome any tendency of the triac to turn off prematurely. <IMAGE>

IPC: G06F11/267
Filed: 1992-11-03
Abstract: A duplex computer system is constructed of two computer (or processor) systems FC1, FC2 connected with a common backboard bus L1 and a plurality of I/O units to be controlled by the computer systems. Each computer is composed of a CPU unit 10 having a self-diagnosis function for outputting a ready signal CPURDYO indicating whether or not the operations can be normally accomplished, a communication interface unit 2 for the backboard bus, and a duplex control unit 15 which receives the ready signal outputted from the CPU unit for controlling the two computer systems to determine which of the computer systems is brought into a control status while the other is brought into a standby status. There is no independent duplex control unit between the two computer systems and thus trouble in one computer system will not influence the operations of the other computer system. <IMAGE>
