Title: Integrated circuit high voltage distribution and control systems
Inventor: SIMKO RICHARD THOMAS
IPC: H01L27/105
Filed: 1983-04-07
Abstract: Low power consumption methods and apparatus for distributing and controlling on-chip generated high voltage are described, e.g. for programming nonvolatile memory arrays and the like. A selected node is charged to a first potential while remaining nodes are charged to a second potential. The selected node(s) is (are) then isolated and charged to a high potential, eg 10-50 volts, by an on-chip device. The high potential charging device may sense the potential of a node and only be enabled to charge that node to a high potential if the sensed potential is above a given potential, ie at the first rather than the second potential. The arrangement reduces the current requirement and allows the use of an on-chip charging device.

Title: Method to zero-set a gas sensor in a gas-fed incubator
Inventor: LOSCHER HELMUT
IPC: G01N27/18
Filed: 1984-04-25
Abstract: To calibrate or set the zero point and eliminate drift from a CO2 sensor 2 exposed to an atmosphere in a chamber 10, for cultivation of biological cells, tissues, or of microorganisms, the sensor includes a reference portion 2a and a measuring portion 2b, and, during a calibrating phase valve 29 causes the reference portion to be exposed via 28 to the same gas which is within the chamber 10, and which is to be measured. The resulting output signal should be zero; if, however, due to drift or other changes in the zero-set of the sensor 2, it is not zero, the resulting output signal is stored and then algebraically added to the output signal derived from the sensor when the reference portion is again exposed to a reference gas of known composition, for example air from 26. The correction signal is subtracted from the signal sensed when the reference portion 2a is exposed to the reference gas, and only the measuring portion 2b is exposed to the gas to be measured, within the chamber. <IMAGE>

Patent GB-2144594-A (GB)
Title: Method for DC pulse modulated arc welding
Inventor: WRIGHT WILLIAM E
IPC: B23K9/067
Filed: 1984-07-18
Abstract: In a method of arc welding, the width of constant current pulses supplied by a power supply is modulated to provide a selected power flow to work pieces (1). This method of arc welding is especially useful with a type of pulsed DC arc welding wherein the ratio of peak current to maintenance current is maintained at a selected high value and the current is cycled in a time duration whereby oxides on the surface of the work pieces are dissipated when making the weld. When used with this type of pulsed DC arc welding the present method is especially suited for fluxless welding of aluminium work pieces, such as thin wall aluminium tubing used in making heat exchangers for air conditioning. <IMAGE>
Patent GB-2162234-A (GB)
Title: Releasable fastening mechanism for vehicle tilting cabs, bonnets or boots
Inventor: MORRIS BARRY STANLEY
IPC: B62D33/07
Filed: 1984-07-25
Abstract: The fastening has a latch (6) pivoted to a mounting (1) by a pivot pin (7) and cooperating with a striker (5). A locking pawl (9) biassed by a spring (17) normally holds the latch (6) against pivoting so as to retain striker (5) trapped in a mouth (8) of the mounting. A detent lever (15) is pivoted at its mid-point (16) on the mounting, and a hooked end (21) is engageable with a pin (23) on the locking pawl to hold the pawl inoperative as soon as the pawl has been released from the jaw by actuation of the associated hydraulic or cable actuator. This prevents the mechanism from re-locking before the striker has left the mouth (8), to prevent mechanical damage, but as the striker leaves the mouth it engages with one end (24) of the detent lever (15) to disengage the hooked end (21) from the pin (23), thereby releasing the pawl for subsequent re-locking of latch (6) when the striker is urged back into the mouth (8). <IMAGE>

Title: Sound recording interface for a domestic video cassette recorder
Inventor: MARLOW PETER JOHN COURT
IPC: G11B27/34
Filed: 1984-10-23
Abstract: A sound recording interface for a domestic video cassette recorder which creates a standard television signal on a spare UHF channel of a 'black' picture and the desired sound. This signal can be recorded and played back by the video cassette recorder like any other television signal. The interface is connected to the video cassette recorder via the UHF aerial feed in such a way as not to interfere with broadcast television signals or radiate unwanted signals. Radio programs can therefore be recorded on a video cassette recorder taking advantage of the long length of video tape (as compared with audio cassette) and the sophisticated timer on the recorder. Any mix of radio and television programs can be recorded. Reference is made to the provision by the video signal generator of a "non-black" picture, and moving colour display changing according to level or frequency of audio input. <IMAGE>
Patent GB-2152780-A (GB)
Title: Distance measurement
Inventor: MARSHALL IAN
IPC: G01C3/32
Filed: 1984-11-13
Abstract: A distance measuring arrangement uses two optical sensors spaced apart from each other along the optical axis of the arrangement so that the images of a distant object have different degrees of de-focus at each sensor. The two resulting electrical signals have different contrast values from which the range of the object can be determined. The contrast is taken to be represented by a high frequency component of the signal amplitude which varies as the image is scanned across the sensor. <IMAGE>
Patent GB-2167261-A (GB)
Title: Optical fibres
Inventor: CANNELL GEORGE JAMES
IPC: H04B10/071
Filed: 1984-11-16
Abstract: The optical time domain reflectrometry (OTDR)/backscatter trace of an optical fibre is obtained used a light emitting diode (LED) (19) as the source in place of the more conventional laser diode. The LED 19 is driven to produce a pulsed output which is applied to one end of the optical fibre 20 via a 3dB fibre coupler 21. Photons output from the fibre are coupled to a detector 22 such as an avalanche photodiode operating in a photon counting mode. The detector output is integrated (13, Fig. 1) and used to provide an OTDR/backscatter trace on an oscilloscope or chart (18, Fig. 1). For a 1.3 mu m LED, a germanium avalanche photodiode detector cooled to temperature of the order of liquid nitrogen temperatures is required, but at shorter wavelengths an uncooled silicon photodiode suffices. The apparatus may be used as a fault finder for use in the field. It is simple to operate and safer and cheaper than one employing a laser diode as the source. <IMAGE>

Title: Detecting horizontal colour changes in a video signal
Inventor: PARLETT MARK EDWARD
IPC: H04N9/64
Filed: 1986-01-08
Abstract: Delays 3,4 provide three constructive lines of video chrominance signal CH0, CH1, CH2. These are combined 24,25 to provide to signals which are multiplied 26 to provide an output indicating a change in the colour subcarrier phase i.e. a horizontal colour change. The amplitude of CH0, CH2 are also compared, by adder 29, to indicate a horizontal transition. Either output signal provides a transition detected output, which is used to alter the configuration of a PAL decoder (Fig. 3). When a change in chrominance is detected the decoder uses only one line of video signals in the decoding of the chrominance and luminance and in the separation of the colour difference signals. If no chrominance change is detected three adjacent lines are used in the decoding. <IMAGE>
