Title: Reduction of cumulative error effects when decoding time-sequential digitally-encoded data
IPC: H04N1/419
Filed: 1978-09-22
Abstract: Digitally encoded time sequential, bidirectionally decodable data, for example a run-length encoded facsimile telegraphy signal, in blocks between points of reference, for example end of line codes, is decoded by decoding the first half of a block of data from a first point of reference to the mid-point of the block in a forward direction and decoding the second half of the block from the mid-point to a second point of reference in a backward direction from the second point of reference. A facsimile telegraph receiver using this type of decoding produces a better quality image as transmission errors are only able to accumulate for half a scan line.

Title: Separation of gas mixtures using a swirl tube
IPC: B04C5/04
Filed: 1978-09-22
Abstract: In the separation of a gas e.g. isotope, mixture using a swirl tube 10, the gas mixture is collected under positive pressure at 36, 37 and fed into the swirl tube 10 so as to flow from one end to another along a helical path, the gas being caused to expand as it is fed into the swirl tube in the direction of flow, e.g. by means of a nozzle 21 which is divergent in the direction of flow. The flow velocity in the swirl tube is higher than in conventional swirl tubes and can be increased further by rotating the swirl tube in the direction of flow thereby avoiding friction losses. <IMAGE>

Abstract: A plurality of single strand or multi-strand filaments in side-by-side relationship, e.g. optical fibres or electrical wires are drawn through a reservoir of viscous liquid polymer so that the viscous polymer adheres thereto. A web of the polymer material occupies the space between adjacent fibres or wires and thereby connects them. The fibres are then pulled from the reservoir through an appropriate shaped orifice to form a flat cable. The cable is cured in an oven or other curing device.
Patent GB-2034430-A (GB)
Title: Boosters for vehicle brakes
IPC: B60T13/567
Filed: 1979-10-19
Abstract: In a servo booster assembly for vehicle braking systems a generally cylindrical booster housing comprises two or more identical segments 1 which are connected together along joint faces 2 which extend radially relative to the booster axis and in planes that include the booster axis. The joints may be welded, bolted or banded together. This arrangement not only makes for easier production as the casing segments are identical, but any reaction forces in operation of the booster are transmitted along the casing joint lines and not across them as in known boosters. Thus these forces do not tend to separate or distort the casing segments. The casing segments include a groove 8, for locating a flexible diaphragm (13) dividing the housing into two chambers. <IMAGE>

Patent GB-2083504-A (GB)
Title: Vapour cleaning plant
IPC: C23G5/04
Filed: 1980-09-11
Abstract: Vapour cleaning plant has in a wall of its tank 10 temperature sensors 20-22 which are arranged to control heating of the cleaning fluid in the sump 12 so that a desired top level of the cleaning vapour is maintained in the tank. In non-use periods reduced heating is effected but on fall of the top vapour level in use, e.g. due to loading of cold workpieces to be cleaned, increased heating is brought into effect to restore the vapour level to the desired top level. Cooling coils usually provided at the tank top may be omitted with consequent power saving, and extraction air of rim extraction means may be used to cool the tops of the walls to prevent loss of cleaning fluid due to vapour creep along the walls. Control of the heater may be effected by the arrangement in Fig. 3 in which the difference between the temperature at 20 and 22 is compared at 33 with the output signal of a ramp generator 35. Comparator 33 controls the heating of the bath via relays 36. If the sensor 21 detects a substantial fall of temperature, gate 34 is opened which has the effect of overriding the control by sensors 20, 22 and applying full power to the heater. <IMAGE>

Title: Improvements In and Relating to Process Controllers and Programme-controlled Machines
IPC: D06F34/28
Filed: 1981-02-04
Abstract: A process controller, suitable e.g. for programme controlled washing machine 1-4, performs a sequence of operations in accordance with user commands provided by user controls. It enables a user to check components of the machine by means of the user controls and microprocessor 9. The controller provides a test mode in which each user control becomes dedicated to a particular component which can then be selectively energised by means of its dedicated control so as to assess its operational state. The process controller is arranged, during operation, to perform periodic checks on signals provided by sensors and to assess whether or not each signal is within specified limits at a specified time. Failure of a periodic check results in the display of a code which identifies the sensor involved in the check. <IMAGE>
