Patent GB-2308007-A (GB)
Title: A process for producing burn-in boards
Inventor: COMERFORD PAUL
IPC: H05K3/00
Filed: 1995-12-08
Abstract: Burn-in boards are produced by insertion of sockets (4) into a board (2) of polyimide material having a glass transition temperature of 240{C. A runner (10) is mounted centrally and longitudinally to the lower surface of the board (2) and during soldering, this is used to help ensure that there is uniform application of solder across the width of the board (2). Before application of flux, the assembled board (12) is baked at 110{C for 2 hours for removal of moisture from the board. Before soldering, there is pre-heating by passing over heating plates at a temperature of 175{C. Effective soldering is ensured by use of the runner (10) and the solder composition is 96% Sn/4% Ag to provide reliable joints for the life of the burn-in board. The soldered board is tested by use of a universal test panel having a number of connectors for connection of any desired pair of probes to the board. Each socket (4) is tested in turn and integrity of the socket is ensured as a set of through-holes for the socket is individually connected to an edge connector.

Title: Synchronizing signal generating circuit for optical multiple-scanning device
Inventor: MINAKUCHI TADASHI
IPC: G02B26/10
Filed: 1996-09-30
Abstract: An optical multiple-scanning device 1 has a number of scanning laser light beams 21a-21d that scan along a scan path and which are separated along the scan path 11 by a predetermined pitch P and produce an illumination spot of diameter D. A synchronizing signal generating circuit 10 has a single photodiode 6 and a signal processing circuit 9. The photodiode has a width W along the scan path and generates a signal with maximums IMAX and/or minimums IMIN. If the condition W * less than or equal to * P - D/4 is met, or if IMIN is less than or equal to 80% of IMAX, the synchronizing signal processing circuit 10 accurately generates a square-wave synchronizing signal of successive rectangular pulses to indicate that successive scanning laser beams have reached a predetermined position along the scan path.
Patent GB-964716-A (GB)
Abstract: 964,716. Calculating-apparatus. BUCHUNGSMASCHINENWERK KARL-MARX-STADT VEB. April 28, 1961, No. 15447/61. Heading G4B. Clearing mechanism for the keyboard of an accounting or similar machine comprises a clearing push bar which is normally ineffective and is rendered effective only when the machine is conditioned to print and one or more symbol keys are depressed. A depressed locking key prevents clearing in these circumstances. If a key 2 is in operated position and a 'print' instruction is received, setting members 21 for the type slides are released and move to the right until abutments 26 on co-acting setting slides 25 engage the ends of the depressed keys. This movement to the right allows an adjustable plate 27 on the setting member 21 to rotate a holding latch 15, releasing a rivet pin 12 and allowing an intermediate lever 10 to rotate clockwise. This causes a transmission member 7 to drop and hence a clearing push rod 18 to engage a bent end 16 of an actuating lever 5. During the machine cycle the push rod 18 moves to the left, and on its return, its edge 17 rotates the actuating lever 5 counter-clockwise. The bent end 29 of the lever 5 engages a transversely slidable locking bar 4, pushing this leftwards to release the spring-urged keys. At the same time the clearing push rod 18 is raised by the bent portion 16 and by means of an inclined edge 20 acting on a rivet pin 19, lifts the transmission member 7 so that the spring- urged latch 15 can re-engage the rivet pin 12. During the following machine-cycles the clearing push rod 18 will move but its edge 17 is above the bent end 16 of the actuating lever 5 and hence any depressed keys will not be cleared until a new 'print' instruction is received. If a locking key 3 is depressed it prevents the lever 10 from rotating and thus the clearing push rod cannot drop even if the latch 15 is released.
Patent GB-2312184-A (GB)
Title: Making a durable sand mould
Inventor: DARBY DAVID JOHN
IPC: B29C33/38
Filed: 1997-04-11
Abstract: A method for making a durable mould comprises forming a porous mould by applying sand 18 coated with thermo-setting resin to a heated pattern 14, cooling, removing the pattern and impregnating at least those interstices near its surface with a liquid chemical which sets hard and heat-resistant, such as cyanoacrylate, either by suction, pressure, immersion or coating. A porous mould incorporating a cooling jacket is made by applying sand (48) (Fig 5, not shown) coated with thermosetting resin to a heated pattern (44) removing surplus sand to leave a fused layer adjacent the pattern, laying a sheet (50) of a thermo-plastic material capable of being burned off, such as polystyrene, over the surface of the hot layer to follow the contours of the pattern, re-applying resin-coated sand over the sheet, and heating to fuse the re-applied sand whilst burning off the sheet to leave a void constituting the cooling jacket. Holes (52) may be formed in the sheet to accommodate resin-coated sand which forms supporting pillars in the jacket. This porous mould can be made durable by impregnating it with cyanoacrylate.

Title: Electric heater control for a glass-ceramic top cooking appliance
Inventor: HIGGINS GEORGE ANTHONY
IPC: H05B3/74
Filed: 1997-07-17
Abstract: A glass-ceramic top cooking appliance has an inner heating zone with one or more heating elements 8 controlled by a first energy regulator 13, and an outer heating zone at least partially surrounding the inner zone and having one or more heating elements 9 controlled by a second energy regulator 14. The regulators 13, 14 operate in a co-ordinated manner under control of a manual power level selector 22, so that at a full power setting the surface power loading (watts per square centimetre) of the inner zone of the glass-ceramic top is not less than that of the outer zone, and in at least one lower power setting the surface power loading of the inner zone is not greater than that of the outer zone. At the full power setting the appliance may thus have a higher power loading in the inner zone than the outer zone (ie. centre weighting), and in at least one lower power setting the inner zone power loading may be less than that of the outer zone (giving edge weighting) or equal to that of the outer zone (giving neutral weighting).

Title: Controlling a setting element in response to the occurrence of an error.
Inventor: FISCHER WERNER
IPC: G05B9/02
Filed: 1998-05-15
Abstract: Control or regulation of a settable setting clement with integral behaviour is carried out by firstly detecting the actual value of a parameter of an operating system which incorporates the setting element. A target value of the parameter is also generated, and the setting of the setting element is dependent on the difference between the target and actual values. The actual value of the parameter is also monitored so that an error or defect in the system can be recognised. In response to such an error, the setting element is controlled so that it is disposed at least temporarily in a predetermined setting, thus permitting emergency operation of the system. The element may then be controlled in dependence on a simulated actual value based on the predetermined setting. In the embodiment, the setting element is an injection-adjusting device of a high-pressure fuel pump, and it is driven to a predetermined position under certain engine operating conditions such as over-run or idling.
