Patent GB-2165381-A (GB)
Title: A device for and method of reading from a substrate
Inventor: RIGBY BRIAN
IPC: G06Q20/34
Filed: 1985-10-03
Abstract: A substrate such as a transaction card C whether for cash or goods carries one of a pair of algorithm generated numbers. This may be read from the card and fed to signal processing circuitry. The other number of the pair, normally a personal identify number PIN is fed into the circuitry from a keyboard. The circuitry processes the two numbers in accordance with the algorithm to give a result which is compared with a third piece of information which may also be written on the card C. If the comparison is correct, a valid signal issues. The algorithm may be implemented in the circuitry by shift registers SR1, SR2. <IMAGE>

Title: Reinforced screw holes in hollow profile members
Inventor: MOLLER HUBERT
IPC: E06B3/96
Filed: 1986-03-21
Abstract: A hollow profile member (1) has at least one inextensible reinforcement element (2a, 2b, 4a, 4b) embedded therein. Each reinforcement element is provided with corrugations (11) on at least one side substantially transversely to its length direction. The corrugations (11) are provided over the whole length of the reinforcement element and along this one side there is provided at least one elongate screw hole (3, 5) having a preferably circular cross-section and bordering the corrugations. In the manufacture of frames, as for example window-frames or door-frames, two suitably cut hollow profile member parts can be secured one to the other with high strength using only simple threaded bolts or screws, because the threaded bolt or screw is screwed into the said hollow chamber (3, 5) where the corrugations (11) on the one side of the reinforcement element act as a counter-thread to hold the bolt or screw anchored fast in the material of the hollow profile member. <IMAGE>

Patent GB-2228587-A (GB)
Title: Controlling drawing of curtains
Inventor: MESSENGER ALAN GRAHAM
IPC: A47H5/032
Filed: 1989-09-28
Abstract: In response to a close (or open) command signal, a motor 52 drives curtains until they reach a first closed (or open) position, whereupon a further signal is generated which causes the motor to drive the curtains to a second closed (or open) position. As described, the command signals are generated manually at 84, 86, or by a light sensor 82 or by a timer 83 and, via a bistable 76 and logic 74, operate energising and direction control circuits 70, 72 for the motor 52. When the first closed (or open) position is reached, a limit switch 58 opens to de-energise the motor, then after a short delay the logic 74 reverses the motor to move the curtains a short distance until the switch 58 closes again and de-energises the motor. This brief reversal relieves mechanical stress on the system. <IMAGE>

Title: Reducing shock wave losses over aircraft surfaces
Inventor: PARRY PHILIP
IPC: B64C23/04
Filed: 1990-05-22
Abstract: To reduce drag due to the formation of shock waves where the local airflow over an aircraft wing or tail surface becomes supersonic, positively charged ions are produced in the airflow. An electric current through material (B) at the leading edge produces positive ions in the airflow. Electromagnetic inductive panels (C) located where the shock waves are likely to form produce a field which interacts with the positive ions to reduce shock formation, and hence compressibility losses. <IMAGE>

Title: Thermal clearance control method for gas turbine engine
Inventor: SCHWARZ FRED M
IPC: F01D11/24
Filed: 1990-06-18
Abstract: Clearance between blade tips and an annular shroud is controlled by enhancing the thermal response of the engine case and annular shroud during the transient response period following a step change in engine power. A temporary reduction or elimination of the flow of cooling air supplied to the engine case by the active clearance control system ensures that the radius rs of the case follows curve 34 instead of curve 32 leading to an increased minimum clearance delta min. Substituting a flow of relatively warm air for the cooling air leads to a further increase in the response of the case (curve 36) and a further increase in  delta min. <IMAGE>

Patent GB-908789-A (GB)
IPC: H03K17/0412
Abstract: 908,789. Transistor switching circuits. RAMO - WOOLDRIDGE CORPORATION. Oct. 29, 1958 [July 31, 1958], No. 34743/58. Class 40 (6). A transistor switching circuit comprises an emitter-follower of one conductivity type directly connected to the input of a grounded emitter stage of opposite conductivity type. As shown in Fig. 3, when the input to emitterfollower transistor A1 is at the + 13.5 volts level, the emitter of A1 goes positive to switch grounded-emitter transistor A2 off, so that there is delivered - 13.5 volts at the output. When the input to A1 is at its alternative level of - 4 volts, the input to transistor A2 tends to go negative so permitting the transistor to conduct and deliver a zero-volt output; simultaneously the base-emitter diode of transistor A2 prevents the emitter of transistor A1 going markedly negative so that transistor A1 is cut off. An input circuit 10 comprises a transistor 12 which is switched off, so supplying a +13.5- volt input to the switching circuit when its own input is at the -13.5-volt level and is switched on so supplying a -4-volt input to the switching circuit when its own input is at zero volts. The output from transistor A2 thus follows the input to the input circuit 10. Fig. 4a shows an alternative input circuit employing a Zener diode 17 and providing an inversion between input and output voltages. Fig. 5 shows a circuit comprising two switching circuits as shown in Fig. 3, the emitter-followers A1a, A1b being reciprocally coupled between their collectors and bases to provide a bi-stable circuit. The output is taken from between the collector electrodes of grounded emitter transistors A2a, A2b; a transformer output coupling may be used, Fig. 6 (not shown). Diodes 15a, 15b, D3a, D3b prevent saturation in transistors 12a, 12b, A2a, A2b respectively. In this circuit the application of a negative-voltage input to one or other of the input circuits 10a, 10b permits clock pulses, at terminals C, to be applied to the corresponding ones of emitterfollowers A1a, A1b. Similarly, a zero-volt input suppresses the application of clock pulses to the corresponding transistor of the bi-stable circuit.
