Patent GB-2153615-A (GB)
Title: Optical telecommunications systems
Inventor: HEATLEY DAVID JOHN TAYLOR
IPC: H04B10/293
Filed: 1984-10-02
Abstract: A telecommunications systems employs signals transmitted along optical fibres. A broad transmission band is provided and enables both video and a number of speech channels to be provided. The system uses PFM signals which have no baseband component, the baseband component being regenerated in the receiver. The receiver includes a wide-band PIN FET (20), and a demodulator using a pulse counting technique. The received pulses are converted to fixed width by an ECL monostable (25) and the baseband signal obtained by a low-pass filter (26). <IMAGE>

Patent GB-2172777-A (GB)
Title: Code division multiple access communication system
Inventor: TORRE FRANK M
IPC: H04J13/00
Filed: 1985-10-10
Abstract: A CDMA format is used within a network to permit communication between members of a network. Network members are synchronized to each other and are each aware of a predetermined set of code words which has been established. A member desiring to transmit data selects a code word from the predetermined set. If there are unused code words, one of the unused words is randomly selected. If all words are being used, the code word of the farthest user is selected. Since all members are synchronized in time to stable clocks, the range of each user is known. All members of the network are always listening and keeping track of detections of other users and code words. Transmitted signals are a series of pulses with a jitter or sync pulse inserted within each series. The number and location of sync pulses is unique for each code and defines the CDMA code of the signal. A pseudorandom noise generator synchronized to the clock is gated with coded data pulsed with appropriate jitter insertion and transmitted over a frequency determined by the pseudorandom number at any instant in time. <IMAGE>
Patent GB-2168264-A (GB)
Title: Separator drain box
Inventor: MAVROS STRATOS
IPC: B01D45/06
Filed: 1985-12-11
Abstract: It is common for engines of the gas turbine variety to have filters at their air intakes. An example of a system employing such a filter takes the form of a tube or duct into which is drawn the air to be filtered, which tube contains a number of filtering components inlcuding pads of knitted mesh and a series of zig-zag vanes. These vanes remove any entrained water droplets, and the "condensed" water runs down the vanes (under gravity) into what is known as a "drain box", from which it is led away and disposed of. The present invention proposes a novel design of drain box; instead of having the vanes bottom on a ledge in the drain box, above the drain box floor, leaving a gap between the bottom of the vanes and the floor of the drain box, and so allowing re-entrainment of the moisture, the present invention proposes that the vanes be extended to the floor of the drain box in intimate contact with the drain enclosure bottom surface. In addition to preventing re-entrainment, extending the vanes in this way provides additional structural vane support, and results in a stronger, more rigid filter system.

Title: Application of liquid to web or is sheet metal
Inventor: DAWSON TIMOTHY LESLIE
IPC: D06B11/00
Filed: 1987-02-27
Abstract: Accurately predetermined quantities of liquid can be applied from a plurality of needle like or capillary jets (17) to web or sheet material (14) which is moving continuously relative to said jets. The liquid is supplied to the jets (17) at superatmospheric pressure via respective electromechanical valves (20), which are controlled by computer to open and close rapidly so that liquid is fired from the jets (17) in a succession of short pulses. Thus, small quantitites of treatment liquids can be uniformly applied and, in specific cases where the liquid is colouring medium, pre-programmed patterns can be applied in simple and effective manner. The invention is particularly suited to patterning woven or tufted material (eg cut pile, looped pile or tufted carpet); felt; woven or non woven textiles; paper; board; film; coated or non coated webs. The material may be in sheets or webs. <IMAGE>

Title: Workpiece transfer device
Inventor: BURKNER CHRISTIAN
IPC: B21D43/05
Filed: 1987-03-27
Abstract: A device for transferring a workpiece 1 sequentially between processing stations in a press comprises first and second rails 5 on which are mounted grippers 2,2' having workpiece contact surfaces 3 that are inclined to the general direction Ta of workpiece transfer. A limiting stop 4 is formed on one of the grippers. In use, the rails 5 are moved towards one another to engage a workpiece, in a direction S at right angles to the direction Ta. As a result the workpiece is shifted in the direction Ta by an amount  DELTA L until it engages the stop 4. Then the rails 5 are moved in the direction Ta to move the workpiece to the next processing station. The stations need not be equally spaced apart since the displacement  DELTA L can be utilised to accommodate any non-uniformity in their spacing. <IMAGE>
Patent GB-871029-A (GB)
IPC: F16K31/68
Abstract: 871,029. Valves. ROBERTSHAW-FULTON CONTROLS CO. Nov. 27, 1957 [Sept. 16, 1957], No. 37031/57. Class 135. Ambient temperature compensation of a thermostatic control device is effected by an oval apertured bi-metal disc 120 mounted on a part 116 of the thermally responsive means 158 and bent along its major axis so that the arcuate ends of the V arms so formed engage the valve 124. Rotation of knob 80 and shaft 74 rotates a member 38 having wings engaging slots 34 in a gas control cock 20 which is also turned. Slots 90 in the cock engage tangs 96 on a member 92 having arms 98 engaging slots in a member 108 secured to the stem 116 carrying the thermal valve 124 and which is thereby rotated and screwed along a screw 134 prevented from turning by arm 150 engaging slots in the edge of a thermal diaphragm 158 to which the screw 134 is secured. Valve 124 is loaded by spring 132 on to two diametrically opposite points on the periphery of the bi-metallic disc 120 carried by the stem 116. The bi-metal slides the valve 120 along its stem to compensate for ambient temperature changes. Expansion of element 158 moves valve 124 to its seat and slides member 108 along arms 98 against spring 104. Cock 20 has a small port 28 permitting a minimum flow of gas and a by-pass gas passage 184 is also provided. Knob 80 carries a locking disc 44 provided with three projections 50 at different radial positions from the axis of rotation each of which can enter one of two holes whereby the cock allows the minimum flow or cuts the gas off completely.
