Patent GB-2068272-A (GB)
Title: A device for applying a force
IPC: B25B5/06
Filed: 1981-01-23
Abstract: A device for applying a force, such as a clamping device, comprises an electric motor (2) which, when energised, causes rotation of a nut (8) which in turn causes linear displacement of a spigot (9) and of an output element (16). When the output element (16) meets a resistance and is arrested, a resilient assembly (15) is compressed, and relative movement takes place between a rod (17) carried by the output element (16), and a tube (18), carried by the spigot (9). This relative movement is detected by a transducer (20) which, when the movement reaches a predetermined value, delivers a signal which causes the motor (2) to be de-energised. The device enables a predetermined clamping force to be achieved and maintained substantially constant, or varied in a predetermined manner. The device may be used on machine tools. <IMAGE>
Patent GB-2069034-A (GB)
Title: Pile drivers
IPC: E02D7/02
Filed: 1981-02-06
Abstract: An underwater pile driver comprising one or more hydraulic cylinders (6) is operated by the water in which it is submerged. A pump (20) at the surface produces a pressurised water supply and the driver exhausts the water directly into its surroundings. Only a single large-bore high-pressure line (24) is therefore required as there is no return line. By means of a remotely actuated pilot valve (28) the pressure water supply is also used to operate a valve (26) through which the water flows into and out of the cylinder. The valves (26, 28) are disposed on the submerged pile driver frame (2). <IMAGE>

Patent GB-2079267-A (GB)
Title: Manufacture of Optical Fibre Preforms
IPC: C23C16/515
Filed: 1981-07-08
Abstract: In the manufacture of an optical fibre preform by forming a multilayer vitreous coating composed of one or more oxides, in the bore of a glass substrate tube, from a gaseous reaction mixture passed through the tube, the reaction mixture is carried by an ionisable gas and the reaction is activated by plasma flashes occupying the whole of the region of the tube length in which deposition of the coating is required. The plasma flashes are produced by the application of electrical or electromagnetic power pulses of high field strength to the said region of the tube, the tube being substantially filled with unreacted gases, at a constant low pressure, before the application of each pulse. Several methods of producing the plasma flashes, and of effecting the required repeated fillings of the tube in synchronism with the flashes, are described. Fig. 1 shows silica tube 1, microwave cavity 2, pulse generator 3, and tubular electric furnace 4. In another embodiment (Fig. 3), tube 1 contains a tapered silica rod extending coaxially along the length of the deposition region. <IMAGE>

Patent GB-2093327-A (GB)
Title: High pressure liquid cutting means
IPC: A01D34/01
Filed: 1982-02-11
Abstract: High pressure liquid cutting means primarily for cutting grass is provided in which a fine bore nozzle (1) receives water (or other liquid) at high pressure from a pump (2), the high pressure cutting jet (W) of water issuing from the nozzle (1) being received by the orifice (11) of a collector member (10) aligned with the nozzle (1). Water received by the collector (10) is returned to a reservoir (4) for re-circulation by the pump (2) to the nozzle (1) so that a small quantity of water can be repeatedly used for a prolonged period. Multiple or ganged arrangements of nozzles (1) and corresponding collector members (10) may be employed for obtaining a required cutting width or swathe, e.g. in conjunction with a finger bar. <IMAGE>
Patent GB-2098365-A (GB)
Title: Digital electronic timepiece
IPC: G04G9/12
Filed: 1982-03-05
Abstract: A miniature digital electronic timepiece displays time information in a continuously laterally shifting manner upon a dot-matrix type display of a time display section (12) such that more than one digit and less than two digits are visible at any particular instant. The category of information currently displayed, e.g. minutes or hours, is indicated by an identification mark of an identification mark display section 14, and the currently displayed digits can be halted and made completely visible, through size reduction, by actuation of a correction switch (16). Correction of the now stationary digits can then be accomplished by further switch actuation, so that time information correction is simple and rapid, even if only a single external operating member is utilized. <IMAGE>

Title: Foam and sludge separating
Inventor: FIRTH DONALD
IPC: B01D21/00
Filed: 1981-11-03
Abstract: Foam and sludge are separated from a liquid such as industrial waste water and effluent by flowing the liquid at a uniform velocity and substantially horizontally along a tank wherein said sludge settles to the bottom and said foam rises to the top;    removing the sludge from the bottom of the tank at 32 and    removing the foam from the top of the tank at 60. The uniform flow is imposed on the liquid by constraining it to pass through perforated baffles 44, 56. <IMAGE>
Patent GB-2129236-A (GB)
Title: Lamp monitoring circuit
Inventor: EMBREY DEREK MORRIS
IPC: B60Q11/00
Filed: 1982-09-28
Abstract: Lamp bulbs, e.g. in motor vehicles, are monitored by placing a reed switch coil in series with each bulb to be monitored, the failure of the bulb thus causing a reed to change over. In Figure 1, a plurality of reed contacts RS1-4 are placed in series so that if any of them opens when the light switch SW1 is closed, then a transistor Q1 is biased into conduction so as to illuminate a warning lamp W. It is also possible, in accordance with the invention to arrange a reed switch so that it closes when a bulb fails, and such an arrangement can be used for direct operation of a warning lamp. <IMAGE>

Patent GB-2132330-A (GB)
Title: Spiral heat exchanger
Inventor: LAWRENCE STEWART MICHAEL
IPC: F28D9/04
Filed: 1982-12-20
Abstract: In a spiral heat exchanger, two strips 2 and 3 are wound in an interleaved spiral fashion to form flow passages 4 and 5. One side of each flow passage is normally sealed by welding the strip 2 and 3 together, and the other side by means of gaskets 9. Conventionally, these gaskets are mounted on thick flat end covers. In accordance with the present invention, the thick flat or slab like end covers are replaced by facer sheets 11 of comparatively thin material which are sealed to spherical dished plates 13 to form chambers 14 which are pressurised. The chambers 14 may be pressurised either from an external source, or by bleading off working fluids through aligned apertures in the facer sheets and gaskets, or by feeding or discharging the working fluids through the chambers 14. In the latter case, the complex and expensive pockets which are conventionally used may be eliminated, giving a further cost saving. <IMAGE>

Title: Ring laser gyroscope readout arrangements
Inventor: MALVERN ALAN RICHARD
IPC: G01C19/66
Filed: 1983-09-21
Abstract: A ring laser gyroscope is provided with a readout arrangement in which its two readout beams 3, 4 are combined and polarisation thereof modified such that a single combined beam is provided having linear polarisation the plane of which rotates as a consequence of change of phase difference between the readout beams, and thereby corresponds to the rate of rotation of the ring laser gyroscope. As shown, beams 3 and 4 are linearly polarised in the same direction, beam 4 being converted to the orthogonal polarisation by half wave plate 12 prior to combination at 15 with beam 3. The combined beam 13 is passed through quarter wave plate 17 to form the linearly polarised beam, the polarisation direction being determined by orthogonal polarisers 22, 24 and detectors 25, 26. A further combined beam 14 and detector 28 may provide a lock-in and/or path length control signal. Detector 28 may alternatively receive a part of beam 6 leaving reflector 16. <IMAGE>
Patent GB-2128421-A (GB)
Title: Power supplies
Inventor: FENNA DOUGLAS STUART
IPC: H03K17/13
Filed: 1983-10-05
Abstract: A controller to switch an alternating current power supply at zero crossing points generates a plurality of signals (Fig. 2a) having duty cycles of, for example, 50%, 25%, 12% etc. Selected ones of these signals are combined to produce a composite firing signal (e.g Fig. 26), switched at zero crossing points and having a duty cycle dependent on the desired power output. The signal is used to trigger a switch, e.g. a triac 1, which thus energizes a lead 3 from an AC source 2 for selected complete cycles of the source. <IMAGE>
