Patent GB-2189632-A (GB)
Title: Microprocessor video display system
Inventor: MATHIESON JOHN
IPC: G09G1/16
Filed: 1987-04-09
Abstract: In a microprocessor video display system a pixel-mapped video memory (10) can be accessed both by the CPU (12) and by video display logic (14) which delivers video data to the display. Contrary to accepted practice, contention between simultaneous access requests from the CPU and video display logic is avoided by the video display logic deferring its access request for one video memory access period. This is acceptable because: the video control logic can access data at a rate twice that required by the display, the video memory access cycle rate is the same as the CPU clock rate, and the microprocessor accesses the memory for one clock period during operation cycles lasting three or four clock periods. The CPU operation is thus kept at its maximum speed without the video data being adversely delayed. <IMAGE>
Patent GB-2193114-A (GB)
Title: Catalysts
Inventor: JENNINGS DR JAMES ROBERT
IPC: C01G49/00
Filed: 1987-05-26
Abstract: Iron is recovered from spent reduced iron catalyst particles by passivating the spent catalyst by contacting the reduced catalyst particles with an oxidising oxygen-containing gas at a temperature below 100 DEG C, to oxidise the surface layers of the particles without oxidation of the bulk of the particles, reacting the passivated catalyst particles with nitric acid to dissolve the bulk of the un-oxidised iron in said particles, and filtering undissolved material from the reaction mixture, thereby obtaining a nitrate solution. If cobalt is present in the spent catalyst, it will be recovered with the iron. The nitrate solution may be used for the preparation of fresh catalyst by precipitation by addition of a base followed by drying and calcination of the precipitate.

Patent GB-2217540-A (GB)
Title: Automatic biassing of amplifiers
Inventor: DEAVER DAVID K
IPC: H03F1/30
Filed: 1989-03-15
Abstract: In a push-pull amplifier 102-108, a control signal, e.g. stored at 130-132 is selectively altered in dependence upon a supply current sensed at 120 and a current Ic proportional to the control signal is used to control the value of the supply current. The bias applied to output transistors 102, 104 is dependent upon current Ic flowing from source 150 through a biassing resistor 110. This current is maintained constant or increased in dependence upon the positive supply current falling below a predetermined value as sensed by stages 120, 138 to maintain or vary the potential at node 136. Additional circuitry may be included to maintain a negative supply current above a predetermined minimum value. In a modification, the difference between an average supply current and the average output current may be maintained above a predetermined minimum value. FETs may be used in place of bipolar transistors. The arrangement enables the bias current to be substantially independent of variations in temperature and other operating conditions.

Title: Engine idling control apparatus
Inventor: NAKAMURA AKIHISA
IPC: F02D41/08
Filed: 1990-04-26
Abstract: To judge when an engine is idling, a throttle position sensor 9 and an idle switch 10 for changing state at a predetermined throttle opening near a fully closed state of the throttle valve are provided. A circuit 31 judges the state of the idle switch and a circuit 32 updates a minimum value of output values from the throttle position sensor when an idling state is determined. A circuit 36 increases a compensation value when an idle switch state judging circuit 34 judges that the switch 10 is ON and initialises the compensation value when the circuit 34 judges that the idle switch is OFF. A circuit 38 sets a reference value by adding the compensation value from the circuit 37 and at least one predetermined offset value to the minimum value from the circuit 32. A circuit 39 then judges whether or not the engine is idling by comparing the reference value with the output of the throttle position sensor. 
<??>When the engine is judged to be idling, appropriate control, e.g. of a ISCV valve in a throttle bypass, is effected.

Patent GB-2248988-A (GB)
Title: Interface circuits
Inventor: HAN GYO-JIN
IPC: H03K17/693
Filed: 1990-12-14
Abstract: A double voltage source interface circuit comprises an n channel CMOS transistor (n1) coupled to the output of the circuit by way of a latch circuit (1). The input signal is also coupled to the output by way of an inverter (IVa) and a further n channel transistor (n2). A high level source (VH) is applied to the latch circuit (1), whereas a low level voltage source (VL) is connected to the inverter (IVa). The circuit is able to produce an output switching between a low level and the high level of the voltage source (VH) in response to an input which changes from low level to the lower high level of the voltage source (VL) without an unnecessary dissipation of power. The inverter IVa may be of the type shown at IV1; IV2 in figure 1 (not shown). Depending on whether n1 or n2 conducts in response to input level, the level at P or Q is inverted by IVa or IVb. Spurious conduction affecting output level or state is avoided. <IMAGE>
