Title: Detection of synchronisation data
Inventor: WILKINSON JAMES HEDLEY
IPC: H04N5/935
Filed: 1992-06-04
Abstract: Apparatus for detecting synchronisation data in an input serial-bit digital signal formed of a series of word blocks each including a predetermined serial group of m bits forming said synchronisation data, comprises a deserialiser (1) for deserialising the input signal to parallel-bit-bit words where p<m, a delay (2) for delaying at least p-1 bits of each p-bit word by one p-bit word period, and logic (3) for receiving successive groups of 2p-1 bits each formed of a said p-bit word and the adjacent p-1 bits of the preceding or succeeding word. The logic (3) is arranged to detect an initial portion of said synchronisation data by comparing bit sequences in a said group of 2p-1 bits with the bit sequence at the beginning of said predetermined group of m bits. On detection of said initial portion of the synchronisation data, bits of one or more succeeding groups of 2p-1 bits are compared with succeeding bits of said predetermined m bits in dependence upon the position of said initial portion in the corresponding 2p-1 bits. On detection of all m bits of the synchronisation data, a control signal is generated for controlling alignment of the bits of the words of the input signal in parallel form in dependence upon the position of said initial portion of the synchronisation data in the corresponding 2p-1 bits. Applications include digital video tape recorders. <IMAGE>

Title: An intruder detector
Inventor: WRIGHT ROGER MARK
IPC: G08B13/26
Filed: 1992-06-11
Abstract: The invention provides an intruder detector for a parallel wire capacitance sensor arrangement in which there are two sets of sensor wires 12, 14. Each set of sensor wires comprises a field wire 16 energised by a respective oscillator 18, 20 an a ground wire 22 and is arranged to protect or cover a portion of a protected zone. Each set of wires 12, 14 is arranged to have a different capacitance and thus each associated oscillator 18, 20 will have a different centre, i.e. steady state frequency. A digital frequency comparator 24 compares variation in the two sets of sensor wires and sounds an alarm, via processing means 26, when there is a change in the capacitance of one set only. <IMAGE>

Title: Check valve
Inventor: BERGMANN KONRAD
IPC: F16K47/00
Filed: 1992-06-11
Abstract: A check valve in particular for use in water fittings or installations has a valve mechanism which allows liquid flow in one direction only, the valve mechanism being movable reciprocally in order to allow the expansion of liquid downstream of the check valve when the valve mechanism is closed. The valve closure member 5 to biassed against a seat carried by a cylindrical casing 4 which, in turn, is biassed against a downstream abutment 6. A rise in downstream pressure causes the casing 4 to move in the upstream direction without permitting flow through the valve. In a second embodiment (Fig 2. not shown), a disc closure plate (35) seals against the cylindrical wall of an upstream portion of the flow path, a rise in downstream pressure causing the plate (35) to penetrate further into the upstream portion. <IMAGE>

Title: Air launched munition range extension system.
Inventor: HARRIS GORDON LEONARD
IPC: F42B15/10
Filed: 1992-06-26
Abstract: A device having pop-out wings 17, 18 and a guidance and control system is detachably mounted on a munition 14 such as a bomb and is used to extend the range capability of the munition. Prior to launch, the wings are folded together. The control system is contained within a saddle portion 11 of the device, and when the munition is released from the aircraft, the wings are caused to pop out to their flying position. The saddle is secured to the munition through a single bolt 15. Controllable flaps 17b, 18b are installed along the trailing edges of the wings, such flaps being operated to control the pitch and roll angle of the munition. When the target area is reached, the device is jettisoned by detonating a charge which shears the securing bolt 15, thereby permitting the device to pivot rearwardly and separate from the munition. <IMAGE>

Hot spots in an oil- or gas-filled cable installation are cooled by displacing the fluid in the vicinity of the hot spot in opposite directions alternately. As shown, an oil-filled cable 1 is provided with end closures 2, 3 and oil containers 4, 5 are connected to opposite ends of the cable through coolers 12, 13 and conduits 6, 7. Between each tank and its associated cooler is a pump 8, 9 and valve 10, 11. The settings of the valves are varied so that each pump in turn feeds the oil to the tank at the other end. In the arrangement of Fig. 2 (not shown), the oil is merely displaced away from the region of the hot spot so that at one end a small reservoir may be used to hold the displaced oil and at the other end a slightly larger one which will hold both the displaced oil and oil coming out of the cable as a result of thermal expansion. Fig. 3 (not shown) shows an arrangement in which the hot section of cable may be isolated by closure sleeves from the rest of the cable. These sleeves may be of a sort which is permeable if pressure is lost in the rest of the cable.

Title: Multiple channel multiple scene dimming system
Inventor: CARSON STEVEN R
IPC: H05B37/02
Filed: 1997-05-12
Abstract: A lighting control and dimming system 10 utilizes a single traveler conductor 28 for transmitting analog data signals corresponding to a particular light intensity level of dimmers DIM 1, DIM 2, DIM 3, DIM 4, ..., DIM N in a dimmer group. A predetermined binary data word is retrieved from the read-only memory of a controller 30 that may be remote from the dimmers, and is transmitted serially in an analog pulse train over the traveler conductor to each dimmer unit. Each dimmer unit includes a microcontroller 78 and read-only memory (EPROM) 60 in which a group of binary numbers are stored. The analog data signal received by each dimmer is converted to binary and is compared bit-by-bit with each binary number stored in the dimmer EPROM memory 60. A serial bit comparator 72 produces an enable signal 106 in response to a bit-by-bit identity match between the converted analog data signal and the preset binary number stored in the dimmer EPROM. Dimmers enabled by the transmitted analog data signal produce a predetermined scene at a particular brightness level corresponding with one of the stored binary numbers.
