Abstract: A turbulator includes a central elongate support (11) composed of at least two elongate support elements (12, 13) mutually twisted one about the other along their lengths, and at least one elongate element (14) looped about at least one of said support elements so as to define a plurality of elongate loops (15) extending in a helical path along said central elongate support (11) so as to define collectively a spiral. <IMAGE>
Patent GB-2019982-A (GB)
Title: Safety closure device
IPC: F16K21/04
Filed: 1979-04-27
Abstract: The device comprises a conduit 1 for introduction to a pressurised distribution system and a piston 31, 32 automatically displaceable to sealingly cooperate with seating 8 in the event of excessive pressure differential across the piston, e.g. due to a fracture in a downstream pipe. The piston is re-opened by knob 42. As shown, in the normal equilibrium position of the piston, fluid flow is established between the inlet 13 and outlet 12 via arcuate passages 33, 34 in two relatively rotatable piston parts 31, 32. Relative rotation of the latter adjusts the flow duct section at 33, 34 to set the pressure difference across the piston for normal flow conditions. Axial movement of the piston is restrained, as by the frictional grip provided by seal 6, to maintain the piston in its equilibrium position until a threshold value of the pressure difference is exceeded. Other embodiments incorporate, respectively, adjustable magnets and a diaphragm subjected to fluid pressure to provide the axial restraining means. The drive for rotating the relevant piston part may include gearing. <IMAGE>

Title: Modular camera
IPC: G03B19/18
Filed: 1979-05-21
Abstract: A modular cine or video camera has, in addition to its basic functions, at least one additional optional function provided by a snap-in module. Thus a plurality of modules, for alternative sophisticated optional functions, may be acquired as required. The basic functions typically include multiple speed power zoom, testing circuitry for remaining film or tape quantity and battery or power conditions, automatic exposure or illumination control, and sound recording capabilities. In a cine camera, the modules may provide capabilities for producing fading of the exposure and/or sound recording, slow motion, auto exposure override, variable film speed and lap dissolves. In a video camera, the modules may also provide automatic color level control and a color aberration selector. An optional auto-focus module may provide automatic focusing.

Patent GB-2038219-A (GB)
Title: Improved wire drawing method and apparatus
IPC: B21C1/12
Filed: 1979-10-24
Abstract: A method of drawing wire uses a partial turn of wire wedged in an endless groove (32) in a rotating wheel (31) to generate the necessary drafting tension and the wire is cooled by direct contact with liquid coolant as it leaves the sizing opening (36) and while it is wedged in the groove. In a multi-stage apparatus, the coolant would be removed from the wire downstream of the wheel and upstream of the next sizing opening (e.g. by an airwipe 39). <IMAGE>
Patent GB-2038010-A (GB)
Title: Camera with display means
IPC: G03B19/02
Filed: 1979-11-23
Abstract: In a camera which is provided with display means for indicating the aperture setting, exposure time or any other control value to which the camera has been set, the optical display means (42) can also be employed to indicate the condition of switches or other components of the camera, e.g. during manufacture of the camera. As shown, a rod (50) is operable to disconnect the display means (42) from, for example, the standard electronic unit (18) and connect it to components such as switches (S1, S2, S3). A microprocessor in the camera then runs through a test programme instead of an exposure programme and displays the results at 42. <IMAGE>

Patent GB-2069283-A (GB)
Title: Navigation receiver
IPC: G01S1/44
Filed: 1980-02-05
Abstract: A marine navigation aid comprises a beacon which transmits bearing information in the form of two or more VHF signals on the same carrier frequency from respective spaced apart aerials, the two signals having incremental relative phase variation. The signals are transmitted, together with additional preamble, synchronisation, beacon identity and other data signals in two alternating modes. One mode is relatively slow and can be directly utilised by a human listener with a VHF radio receiver. The other mode is fast and can only be utilised by an auxiliary unit attached to the receiver. The preamble indicates which mode follows. The unit includes decoding logic to decode the data signals and programmable logic which, when programmed by the decoding logic, can derive from the bearing information signals the bearing of the receiver with respect to the beacon. The unit includes synchronisation extraction (4), mode extraction (5), timing extraction (6), and bearing signal detection (8) and a micro-processor (10) which drives a visual display unit (12). <IMAGE>

Title: Load raising and lowering apparatus
Inventor: BARNETT MICHAEL IAN MAX
IPC: B66D1/44
Filed: 1981-06-15
Abstract: Apparatus for raising and/or lowering loads, especially for operation of a winch raising and lowering scenery one stage, comprising an hydraulic motor (10) which drives the winch (100) and has an output transmission to one or more lead screws (32) having cam devices (34) which are threaded thereon to be driven along said screws in order, at the lower or upper stop positions for the load, to engage a flow control valve (26) which controls the fluid supply to the motor so as to effect gradual deceleration and acceleration of the load. A separate fluid control valve (24) provides for speed regulation between the end stop positions, and the flow control valve (26) is operable independently thereof.

Title: Producing power from a cryogenic liquid
IPC: F17C9/04
Filed: 1981-06-18
Abstract: A methane-containing cryogenic liquid such as LNG is compressed and used as a refrigerant in the condensers of a first closed circuit which includes power turbine 5 and a second independent closed circuit which includes power turbine 6. The heat exchange medium in the first of the cycles evaporates in heat exchanger 3 at a lower temperature range than that at which the heat exchange medium in the second cycle condenses in heat exchanger 3.

Patent GB-2080777-A (GB)
Title: A container with a safety closure
IPC: B65D50/04
Filed: 1981-07-14
Abstract: A container with a safety closure, preferably a medicine bottle, has a cap (34), as shown a screw cap, which is to be turned when applied or removed, and a blocking mechanism in the form of a resilient blocking means (38) on a collar (32) securely mounted on the neck and a stop face (41) on the closure cap. The cap has an area of reduced wall thickness which in the closed position is opposite the blocking means and makes it possible to act on said means by pressure from the outside. When the cap is turned in the direction of removal from the closed position the stop face engages the blocking means and prevents further turning, unless the blocking means is caused to clear the stop face by applying a pressure to said area of the closure cap. Alternatively blocking means (38) may be moulded directly on neck (31). <IMAGE>

Title: Wheel hub assembly for a vehicle
IPC: B60B35/12
Filed: 1981-09-04
Abstract: This wheel hub assembly is intended for the driving set of wheels of a vehicle which may be steering wheels or otherwise. It comprises mainly a wheel flange, a transmission joint and a rolling bearing. The axial bearing surface between the flange and the inner race of the rolling bearing is limited to an annular ring of small radial dimension but of relatively large diameter. The section of the passage of the flow of heat between the flange and the race is thus substantially reduced.

Title: Burner
Inventor: JOYCE WILLIAM INGLIS
IPC: F23D1/00
Filed: 1982-08-13
Abstract: The invention provides a furnace burner that operates with pulverized fuel. Heated combustion air flows with a rotational movement along a burner tube (9) and a slurry of pulverized fuel in water is discharged into the air from nozzles (14). The effect of the air, and the extended residence time resulting from the rotation of the air, will effect drying of the fuel before it reaches the furnace opening (2). The swirling air can be first supplied in a direction away from the furnace, Fig. 2 (not shown). <IMAGE>
