Patent GB-2298345-A (GB)
Title: Panoramic imaging systems
Inventor: ALLEN BRIAN PHILIP
IPC: A61B6/14
Filed: 1995-07-28
Abstract: An imaging system for producing a panoramic radiograph of a patient's jaw for dental analysis includes an X-ray source 2 carried at one end of an arm 1 and detector means 7 at the other end. A primary diaphragm or slot 6 defines the X-ray beam. The front surface of the detector means 7 carries scintillator material 8 which substantially solely defines the area of the detector means at which the image information is captured. The secondary diaphragm or slot used in conventional panoramic X-ray imaging systems can thus be omitted, giving a less complicated system.

Title: Well servicing fluids
Inventor: VAN OOIJEN JOHANNES ADRIANUS C
IPC: C09K8/06
Filed: 1995-02-01
Abstract: This invention relates to an aqueous well servicing fluid comprising in solution a cesium salt of a carboxylic acid characterised in that the carboxylic acid has: a) at least one carboxyl group and b) at least one other carboxyl and/or hydroxy group. Typical examples are cesium lactate, citrate and oxalate. Use of these cesium salts enables the production of dense brines usable as well servicing fluids.

Title: A lockable ring binder
Inventor: LAW CHUN CHEUNG
IPC: B42F13/26
Filed: 1996-01-24
Abstract: The binder comprises a pair of plates 12 pivotable about an outer edge, each mounting ring halves 14. Opening and closing of the binder is controlled by means of longitudinally-slidable member 16. The outer ends of the plates 12 include downwardly-sloping ramps 18. The rings are closed by moving the control member 16 inwardly so that the underside of the control member abuts against the ramps and pivots the plates downwardly. The rings are locked by engagement of the crossbar 38 of the control member 16 into a hook 40 (Fig 6) formed on the underside of the plates. The rings are opened by moving the control member 16 outwardly so that the crossbar 38 rides up a sloping surface or a pair of hemi-spherical protrusions 42 (Fig 9) on the underside of the plates. Engagement of the crossbar with the base of the hemi-spheres locks the plates open.

Title: Sense amplifier for a semiconductor memory
Inventor: SIM JAI-HOON
IPC: G11C7/06
Filed: 1996-03-12
Abstract: A sense amplifier for a semiconductor memory has a differential amplifier Q13 and Q14 for sensing current signals input to first and second input nodes N1 and N2, amplifying the differences between the two signals and supplying first and second amplified output signals to first and second output nodes N3 and N4. A first feedback circuit Q18 is connected between the second input node and a current control node N5 and has a control terminal connected to the first output node. A second feedback circuit Q19 is connected between the first input node and the current control node and has a control terminal connected to the second output node. The current paths formed by the two feedback circuits lower the voltage of the input nodes differentially, thus increasing the amplification of the two input signals.
Patent GB-2311917-A (GB)
Title: Audio signal decimation
Inventor: GREENWOOD JONATHAN MARK
IPC: H04N5/60
Filed: 1996-04-02
Abstract: Digital audio data occurs in groups of data samples spaced apart in time. The data rate in the groups is much greater than the audio data sampling rate. The audio data may be embedded in the horizontal blanking interval of a video signal as in SDI. The audio data is extracted (2) from the video signal and the samples stored in a FIFO (3). The FIFO (3) removes the spacing between the groups of samples. Sets of the samples are weighted and summed in a multiplier (4) and accumulator (5). Each set to be weighted and summed is displaced by a preset number of samples relative to the previous set to decimate the audio data.

Title: Controlling stages and scanning type exposure
Inventor: TOKUNAGA MASATERU
IPC: H01L21/68
Filed: 1996-04-22
Abstract: In a scanning type exposure apparatus, a reticle coarse movement stage 22 and a wafer stage 20 are simultaneously scanned in a predetermined scanning direction or directions, and a position control system 44 for the reticle fine movement stage detects a positional discrepancy amount between the wafer stage 20 and the reticle fine movment stage 24 and calculates an amount of vibration of a vibration-preventive pedestal 12. Both the stages 20 and 22 are driven and controlled so that positional discrepancy is corrected on the basis of the detected positional discrepancy amount and the calculated vibration amount. Accordingly, even if a vibration of the vibration-preventive pedestal 12 occurs during acceleration for scanning for the stages 20, 22, an error caused by the vibration is taken into consideration and correction is made at a predetermined time interval so that the positional relationship between the stages 20, 24 conforms to a predetermined synchronized relationship.

Title: Combined liquid crystal display and photovoltaic convertor
Inventor: PHILLIPPS JOHN QUENTIN
IPC: G02F1/133
Filed: 1996-12-16
Abstract: A transparent photovoltaic generator structure, formed between plates 2 and 3, is combined with a liquid crystal device, formed between plates 1 and 2, in a single stacked structure. Power derived from the convertor is used to power, or to assist in powering, the display or an apparatus in which the device is used. The advantage is that, because both devices occupy the same area, apparatus incorporating them can be made more compact.

Title: Pay phone security protection circuit
Inventor: WU CHENG-WEI
IPC: H04M17/02
Filed: 1997-10-09
Abstract: Connection of a telephone (70, Figs. 1,2) between the earth wire E of a four-wire telephone line S,A,B,E and a ground terminal GND of a pay phone 11-30 coupled to the four wire line would allow a call to be made by the telephone (70) without payment unless the pay phone is protected against such fraudulent use. In an arrangement to prevent such a free call being made, a rectifier 12 is connected to the communication wires A, B of the four-wire line, and a voltage detection circuit 20 detects the drop in the output voltage of the rectifier 12 caused by connection of the phone (70) between wire E and terminal GND. In response to detection of the voltage drop, a relay 31 disconnects the ground side of the rectifier 12 from the ground terminal GND. A CPU of the pay phone compares the output of the voltage detection circuit 20 with a reference voltage which is set at 1 volt if the pay phone is in a communication state, and at 5 volts if the pay phone is not in a communication state.

Title: Battery housing
Inventor: LORENZ BERND
IPC: H01M50/103
Filed: 1998-02-27
Abstract: The invention concerns a battery housing comprising a water-proof housing wall which surrounds the battery, at least a part of the housing wall being constituted by a resilient material. A portion 28,29 of the resilient material 26 has been weakened compared to the remainder of the resilient material, the weakening being such that the said portion ruptures when the battery temperature exceeds a predetermined threshold temperature.

A plurality of control unit logic elements correspond respectively with the control units (17) and control instruction branching within their respective control unit (17) by defining the next address field. Finally, a branch central intelligence mechanism controls branching between the control units (17) by defining the next address field.

Title: Headgear ventilation device
Inventor: CAMPBELL DONALD ALBAN
IPC: A42B3/28
Filed: 1998-12-08
Abstract: A plastics moulding, ventilation device, includes an elongate flexible strip 3 and a plurality of substantially flat wall sections 5, mutually spaced and lying end-to-end on a smooth curve, which converges with, and meets, the strip at opposite ends. The wall sections are connected to the flexible strip by means of webs 8 and 9, which may contain ventilation apertures, forming trapezoidal ventilation passages 10, between the wall sections and the flexible strip. Instead of lying on the inside of the device, the flexible strip may lie on the outside (figure 5). The inside of the device is covered with a porous sweat band 12 and contains apertures 7, so that air flowing through the ventilation passages keeps the sweat band dry by a wick effect. The outside wall is provided with a layer of pressure-sensitive adhesive, for attaching the device to the inside of the headgear.
