Title: Combustion equipment
Inventor: WARD ROBERT GEORGE
IPC: F23M5/00
Filed: 1987-10-20
Abstract: Combustion equipment (10), which is particularly suited for use with a low power industrial gas turbine engine, comprises a metallic cylindrical liner (11) having a plurality of circumferentially abutting ceramic tiles (25, 26) provided on its radially inward surface. The tiles (25, 26) may be of generally pentagonal or trapezoidal cross section and have circumferentially abutting surfaces which lie in radial planes relative to the longitudinal axis of the liner (11) so that radially inward movement of the tiles (25, 26) is inhibited. A fuel supply nozzle (22) and swirler vanes (20, 21) control fuel and air supply for combustion. <IMAGE>

Title: Hand held winding apparatus
Inventor: NICHOLS DAVID MAURICE
IPC: B65H75/20
Filed: 1987-10-20
Abstract: A winding apparatus for fence wire and the like comprises a substantially rectangular winding frame (1) consisting of elongated steel rod members (2, 3) joined adjacent their ends by cross-members (4, 5). A tubular member (6) is provided substantially at the centre of the frame (1) and a screw-threaded rod (11) forming part of a handle (7) is pivotally mounted in the tubular member (6). A hand gripping part (10) of the handle is provided at one end of the rod and is provided with two projections (13) which are arranged to be located on either side of the frame (1). A wing nut (12) is engaged with the other end of the rod (11). When the wing nut is tightened, relative rotation between the handle and the frame is prevented by virtue of the engagement of the frame by the projections (13) but when the nut is loosened, the projections can be lifted clear of the frame to permit relative unwinding rotation to take place between the frame and the handle. <IMAGE>

Title: Cargo securing means
Inventor: ROWLEY KEITH
IPC: B60P7/08
Filed: 1988-04-18
Abstract: Cargo securing means according to the invention includes two plate like components 12, 32 pivotally connected together by a hinged joint at their respective lower ends 14, 34 formed by a bolt 60 projecting through respective elliptical holes 26, 46.

Title: Power generation from tides
Inventor: LUCY RICHARD JOHN HAMPDEN
IPC: F03B13/26
Filed: 1990-01-23
Abstract: Power generation apparatus driven by the tides includes one or more floats 118 a b c d e or float assemblies which may comprise scrap containers sealed to make them buoyant. They are moored by running tackle 120 a b c or other selectively controlled restraining means in tidal waters e.g. by cables running in a continuous loop round guide pulleys between a supporting gantry 110 and a seabed anchorage 116, for controlled rising and falling motion on or submerged in the tidal waters and this motion is controlled and converted, e.g. by harnessing the runs of cable to energy conversion means, for generation of electricity or other power output. The vertical movement of the floats may be regulated by braking means acting on the running tackles. The floats could be fillable with water to assist their downward travel. Instead of running tackle 120, the floats could be connected to pivoted arms or guided within frames with the drive and braking being provided through a rack and pinion arrangement. <IMAGE>

Title: Circuit arrangement for an anti-lock-controlled vehicle brake system.
Inventor: BLECKMANN HANS-WILHELM
IPC: B60T8/92
Filed: 1990-11-02
Abstract: A circuit arrangement for an anti-lock-controlled vehicle brake system serves for processing sensor signals obtained by means of wheel sensors (5) and for generating braking pressure control signals. The circuit arrangement contains two micro-controllers (1, 2) interconnected by data exchange lines (7). The wheel sensor signals are processed concurrently by the micro-controllers independently of one another and exchanged signals between micro-controllers are checked for consistency. A deviation of the exchanged signals due to malfunctions is signalled to a safety circuit (8) which, compares the signal with a time standard derived from dock generators (TG2, TG3). Any change in the signal, or a failure in the time standard, causes a cut-off of the power supplied to solenoid valves (L1...Ln) in the brake line. <IMAGE>

Patent GB-918843-A (GB)
IPC: A24C5/34
Abstract: 918,843. Cigarette-making machines. POCOCK, F., AHERN, R. A., and MOLINS MACHINE CO. Ltd. June 15, 1959 [June 16, 1958], No. 19211/58. Class 130. [Also in Groups XIX and XXIII] An apparatus for testing the cross-sectional size of a cigarette or like rod similar to that of Specification 888,478 in which the rod R is passed through an orifice 25 to which air under pressure is supplied, variations in rod size producing variations in the air pressure, is modified in that the orifice is formed by an apertured member whose shape can be altered to enlarge or contract the aperture. The rod R passes through a pair of orifices in discs 25, 26, of rubber or like material which can be compressed by a screw threaded member 33 to vary the orifice size. The discs 25, 26 are carried by a spacer member 27 an annular space 31 in which is supplied with air under pressure which flows through ports 32 into the space around the rod R from which it escapes through the orifices 25, 26 at a rate dependent upon the rod size. The chamber 31 is connected to the pressureresponsive device described in Specification 888,478 which may operate a signal or a device to control the tobacco feed or reject defective cigarettes. A thrust washer 37 prevents torsional stress being transmitted from the adjusting member 33 of the disc 25.
Patent GB-2252364-A (GB)
Title: Fluid pressure intensifier
Inventor: CREASEY ROGER HAROLD
IPC: F04B9/107
Filed: 1992-01-23
Abstract: A fluid pressure intensifier comprises a reciprocable ram (H) in a high pressure generating chamber with a common low and high pressure port leading to check valves (D, I), the first (D) permitting low pressure fluid inflow to chamber (F) and the second (I) permitting high pressure fluid outflow from chamber (F). A piston (G) is connected to the ram (H) and has a larger diameter. A cylinder in which the piston moves defines a low pressure chamber (E), and low pressure fluid fed thereto acts on piston (G) to displace the piston (G) and ram (H) in a ram delivery stroke. A fluid outlet route from the low pressure chamber (E) to exhaust is also provided. A shuttle valve (A, B) serves, to open the inlet route and simultaneously close the outlet route, and in a second position to close the inlet route and simultaneously open the outlet route, and a lost motion mechanism (M, N, J, K, L) between piston (G) and the shuttle valve (A, B) ensures that, towards each end of the ram stroke, the shuttle valve means is automatically displaced to the other of its two positions. <IMAGE>

Patent GB-2253681-A (GB)
Title: Gas valves
Inventor: HARGREAVES ALAN GEORGE
IPC: G05D16/18
Filed: 1992-03-05
Abstract: A flow tube 10 has its inlet 12 and outlet 13 separated by a curved wall 14. An aperture 15 in this wall forms a circular valve seating 16 against which a valve closure member 17 abuts. The closure member is carded on a valve stem 18 passing through a control body 11 attached to the flow tube and divided into a stack of control chambers 25-28 by control diaphragms 29 and 30. The valve is controlled by feeding gas 40 at suitable pressures into various control chambers. Flutter (oscillations) can be caused in such valves by sudden changes of pressure, eg by the generation of pressure and flow pulses in the main gas flow which in turn produce force pulses on the valve closure member. To reduce this, two control chambers 25 and 26 are both fed from the gas inlet, the path 50 to one chamber being constricted relative to the path 51 to the other. These chambers have matching diaphragm areas, to cancel out the effects of long-term pressure changes. <IMAGE>

Title: Method of depositing a pecvd teos oxide film
Inventor: CARLSON ARVID C
IPC: C23C16/505
Filed: 1992-06-15
Abstract: In a method of depositing PECVD TEOS oxide film (12) for a semiconductor device positive charge in the film is reduced by controlling the stress of the TEOS oxide film as-deposited. The positive charge in the PECVD TEOS oxide film (12) can be reduced by forming a film having a tensile stress as-deposited followed by an annealing step at 900 DEG C in oxygen and hydrogen chloride. The tensile stress in the film is obtained by controlling the amount of low frequency RF in the reactor or by reducing the RF power to reduce ion bombardment. <IMAGE>
