Patent GB-2187317-A (GB)
Title: Security system
Inventor: AYTON JOHN BARR
IPC: G08B25/00
Filed: 1987-02-24
Abstract: A security system employs a radio tag and a plurality of radio tag receiving heads positioned at various locations. The radio tag is activated when positioned close to a reading head. On activation the radio tag transmits an identification signal which is received by the reading head and passed to a central processing means which may display/record it together with location and time, or may control access.
Patent GB-2207210-A (GB)
Title: Cleaning lance
Inventor: WILLIAMS MICHAEL JOHN
IPC: F01D25/00
Filed: 1987-07-14
Abstract: In some aircraft operating environments the high pressure turbine blades, virtually the hottest part of the jet engine, are susceptible to the formation of surface deposits which can substantially impair the cooling efficiency of the blade. In particular, these deposits tend to block the cooling air exit holes in the leading edges of surface cooled blades. A lance for cleaning the deposit from the leading edge and from in and around the exit holes has a nozzle for directing a jet of cleaning material, eg fine grit or pressurized water at the edge and into the exit holes. Clean air is also directed throughout a cleaning cycle into exit holes upstream of the cleaning jet in order to purge grit from the internal gallery communicating with the exit holes and to prevent the grit being blown back into the cooling air supply system. <IMAGE>
Patent GB-2207828-A (GB)
Title: Automatic focusing
Inventor: LAM WING-SHEUNG SAM
IPC: G02B7/36
Filed: 1987-08-07
Abstract: One known auto-focusing system for photography relies upon detecting contrasting light and dark areas on the subject to be brought into focus. This is satisfactory in good lighting conditions but does not work if flash illumination is needed. According to a prior system the focusing is achieved in such circumstances by illuminating the subject with the light from a powerful LED passing through a grid. The LED is expensive and requires large amounts of energy. The invention overcomes this by using a simple filament bulb and focusing the bright filament onto the subject to provide a light area. <IMAGE>

Title: Brooch spring pin
Inventor: STOKES DAVID
IPC: A44B9/16
Filed: 1987-10-07
Abstract: A brooch spring pin designed for use on brooches incorporates the catch into the pin itself, by use of a spring 7 inserted into a tube 4 behind a pin 3 with protruding thumb grip. The pin 3 travels backwards along the tube 4 when pressure is exerted on the thumb grip enabling the pin to disengage from the securing ring figure 2. When pressure is removed the pin resumes its rest position whether engaged into the securing ring 2 or not. The pin pivots on an ordinary hinge 6, enabling easy fitting and removal of the brooch as required. <IMAGE>

Title: Carton sleeve
Inventor: MAY GORDON EDWARD
IPC: B65D5/04
Filed: 1987-12-11
Abstract: An open-ended carton sleeve (10) formed from a blank can be loaded with a product container (12), when in a partly erected state, and then sealed in a closed position around the container (12) while leaving the ends of the sleeve open. The sleeve blank has panels which are separated by pre-determined fold lines which permit the blank to be erected so as to form a base (21), sidewalls (22 and 23) and flaps (24 and 25) turnable inwardly so as to overlap each other and to be sealable together to complete the formation of the sleeve. Each sidewall (22 and 23) comprises first and second wall portions (22a and 22b) and (23a and 23b) which join each other along fold lines (26 and 27) which permit the sleeve to be wrapped around in a tightly conforming relationship to the product container (12) loaded therein. To provide longitudinal restraint and thereby hold the product container (12) entirely captive within the carton sleeve (10), longitudinal slots are formed in the sidewalls into which flange portion of the container (12) are held captive. <IMAGE>

Title: Vehicle engine output control apparatus, eg to prevent wheel spin
Inventor: HUBER WERNER
IPC: B60K26/04
Filed: 1990-10-17
Abstract: A control member, eg throttle valve, of a vehicle engine is actuated normally by the vehicle driver using a pedal (4) which acts on a first link (14) against a return spring (30). If required however, eg if wheel spin is detected, the throttle valve (8) may be actuated to reduce engine output by a servomechanism (40) acting on a second link (16). A coupling spring (18) is provided to urge the links (14, 16) into abutment at stops (20, 22). The coupling spring may be relatively weak since it is not under tensile stress from the return spring (30). The layout of the apparatus may be rotary instead of linear. <IMAGE>

Filed: 1990-10-31
Abstract: A temperature control apparatus of learning type for a furnace which runs repetitively with a certain profile of temperature change with time models 9 the response of the furnace and its controller 40 to the desired temperature profile input from the memory 7. For each cycle of the repetition of the temperature profile, an adjustment input (@) is calculated using the model 9 operating on the error between the preset temperature values (r) for the profile and the actual temperatures (y) of the furnace. On each successive repetition of the temperature profile, the adjustment input (@) is applied to the system to cause the furnace temperatures (y) to reproduce the desired temperature profile, and the model updates the adjustment input values. A furnace model (21, Fig 8) may also be used to generate initial adjustment input (@) values before the furnace itself is operated. <IMAGE>

Title: Memory management unit having cross-domain control
Inventor: WELLAND ROBERT V
IPC: G06F12/10
Filed: 1992-03-27
Abstract: A memory management unit (MMU) has cross-domain control for controlling a CPU's right to access a memory 406 for performing an operation. The MMU includes a translator 426, 436, 446, for translating a virtual address issued by the CPU 402 into a physical address 440, a data domain number (DDN) 434 and an address domain number (ADN) 438 both corresponding to a domain (a portion of the virtual address space), and a permission 442. An environment controller 462 determines if the ADN corresponding to the operation is allowed access by the CPU. The translator generates the DDN of tagged data specified by the CPU if the tagged data is a pointer. Logic 456 evaluates the permission and either stops the operation or allows it to continue. Cross-domain control logic 432 evaluates the ADN and DDN to detect the attempted flow of domain specific information as a result of the operation, can prohibit the flow of information between domains and can also prohibit the flow of control by the CPU between domains. <IMAGE>
