Patent GB-2185489-A (GB)
Title: Adhesive substances
Inventor: COPE ROY
IPC: C09J105/00
Filed: 1987-01-15
Abstract: An adhesive substance is made by the treatment of the walls of yeast cells in such a manner that they acquire adhesive properties. The yeast is preferably Saccharomyces cerevisiae. The yeast may be yeast that has been propagated in a brewing process. The treatment may comprise the subjection of yeast cells to alkaline conditions, which in turn may be followed by acid conditions. Alternatively the treatment may comprise the subjection of yeast cells to treatment with an enzyme, such as a  beta -glucanase, that breaks down constituents of the cell walls. The resultant adhesive substance may be used alone as an adhesive or be mixed with other materials to form an adhesive. The adhesive preferably contains water. If applied to absorbent surfaces the water is absorbed and the adhesive bonds the surfaces together and is itself water- resistant.

Title: Hydraulic brake system
Inventor: SCHONLAU JUERGEN
IPC: B60T13/52
Filed: 1989-01-10
Abstract: A hydraulic brake system for an automotive vehicle comprises a master cylinder (37), wheel cylinders, a vacuum brake power booster (2) and a control unit for generating a controlled pneumatic pressure for the vacuum brake power booster (2). The vacuum brake power booster (2) generates a controlled hydraulic pressure which serves to generate in the master cylinder (37) an operating pressure for actuating the wheel cylinders of the brake system. This operating pressure acts via a duct (35) upon a sensing piston (44) which, in turn, converts the operating pressure into a reaction force which can be felt at the brake pedal. The master cylinder and the pheumatic control unit are combined to form a construction unit and are arranged at a location separated from that & the pneumatic brake power booster. <IMAGE>

Title: Non-destructive testing for cracks in metals
Inventor: SADEGHI SEYED HOSSEIN HESAMEDI
IPC: G01N27/90
Filed: 1989-07-07
Abstract: In a non-destructive method for the detection of surface cracks in metals, an eddy current is induced by two U-shaped inducers in the surface region of a workpiece under test, at a frequency sufficiently high to generate an alternating magnetic field solely in the skin region of the workpiece. Thai alternating surface magnetic field is interrogated by means of a relatively small electro-magnetic induction sensor, having regard to the overall area of the induced magnetic field. The sensor provides a voltage output which is analysed, preferably in real time, to yield an indication sensor. <IMAGE>

Title: Modulated composition composites produced by vapour deposition
Inventor: MATTHEWS ALLAN
IPC: C23C14/00
Filed: 1991-03-08
Abstract: Modulated composition composites are formed by vapour deposition of evaporant material on to a substrate in which the evaporated material reacts with one or more reactive gases admitted to the deposition vessel. The composition of the deposited layer is modulated without discontinuous variation by the continuous or semicontinuous variation of the availability of the reactive gases in the deposition chamber (figs 1, 2). Materials deposited are zirconium / zirconium oxide fibres, tungsten carbide and films based on chromium / oxygen / nitrogen / carbon. The adjustment of the input of the reactive gases may be made by manual or automatic control of the inlet valve. <IMAGE>

Title: Updating a transformation map for real-time digital video
Inventor: STARR MATTHEW RAYMOND
IPC: G06T1/20
Filed: 1991-03-27
Abstract: A look-up table used to process real-time digital video is updated without the need to interrupt the digital video signal processing. An SRAM normally receives from latches 3 and 4 video and control data respectively from latches 1 and 2, and provides an output dependent thereon via latches 5 and 6. When the SRAM is to be updated, host addresses are applied to latches 3 and 4 from latches 7 and B, and new data for the SRAM is applied through latch 9. The least significant bit applied to latch 8 is held at a predetermined value, e.g. zero, during signal processing clock cycles, and at the complementary value, one, during update clock cycles, so that the updating is applied only to half the lockup table without affecting the half used for signal processing. When that half is updated, the LSB applied to latch 8 is reversed to update the other half of the table. There is a small loss of accuracy or resolution due to the loss of the effect of the least significant control bit. <IMAGE>
