Patent GB-2136313-A (GB)
Title: Air Intake Equipment
Inventor: SHACKELL JOHN
IPC: B01D51/02
Filed: 1984-03-16
Abstract: The equipment, e.g. for gas turbine engines, and usually of the three-stage sort, comprises a first vane stage 5 for removing the bulk of the water. Preferably a second coalescer stage 8 for coalescing - small droplets passing through the first vane stage, and a third vane stage 14 for removing the coalesced droplets are included. To provide anti-icing facilities, it is proposed to heat the first stage 5 of such equipment by using a self- regulating polymer in the form of strips or a coating, the polymer being such as to become non-conductive upon reaching a predetermined temperature. The coalescer stage 8 may also be heated. The first vane stage 5 may be preceded by a sea or fresh water scrubbing spray. <IMAGE>

Title: Improved solvent recovery
Inventor: RIVET JOHN
IPC: B01D53/14
Filed: 1984-08-03
Abstract: Solvent recovery from a gas mixture is effected with the mixture flowing upwardly past an array of horizontal tubes (5) which carry a heat exchange fluid (e.g. a primary refrigerant). Solvent condensed on the upper tubes in the array (5) drips down counter current to the gas mixture. Thermal recuperator coils (3, 7) may be linked in a run-around system by pipes (10) with a pump (11). Solvent in a sump (9) can be warmed by the incoming gas mixture via a spray pipe (6). <IMAGE>

Title: Abrasive blast cleaning method and apparatus
Inventor: MIYAHARA SHUJI
IPC: B24C1/00
Filed: 1984-09-18
Abstract: In the production of particles for abrasive blast cleaning, liquefied carbon dioxide, supplied by a vehicle 6, is expanded through a nozzle in a snow-making device 1, thereby solidifying at least a proportion of it into a powder. The powder is sprayed with water from a tank 4 via a further nozzle thereby coating the carbon dioxide particles with ice to form composite particles. The particles are then formed into pellets 27 by a pelletizer 11 and are fed via a hopper 27 and sequentially operated vessels 13a, 13b, into a compressed-air line 18 subsequently to be projected against the object 25 to be cleaned through a nozzle 17.

Title: Arrangements for converting rotary motion to linear motion
Inventor: STIDWORTHY FREDERICK MICHAEL
IPC: F01L13/00
Filed: 1984-10-26
Abstract: An arrangement for converting rotary motion of a camshaft (1) into linear motion of a reciprocable valve (9) employs a reciprocable cam (2) which is rotatable with the camshaft but is radially displaceable relative to the camshaft which extends through a slot-shaped aperture in the reciprocable cam. The profile of the reciprocable cam is held in engagement with a fixed reference roller (3) and the bucket (7) of valve is held in engagement with output rings on the cam. In the course of rotation of the camshaft, the cam lobe causes radial displacement of the cam on the camshaft with attendant movement of the valve. <IMAGE>

Title: Underwater craft
Inventor: OLENSKI ZDZISLAW JOSEPH
IPC: B63G8/00
Filed: 1984-11-20
Abstract: An underwater exploration craft consists of a pressure vessel which may contain one or more operators and which has one or more propellors which are adjustable in order to give the craft manoeuvrability. It is analogous to an underwater helicopter. The craft may be used for difficult submarine work at great depths, and is particularly valuable in undersea salvage operations where its manoeuvrability enables lines to be attached to an object to be lifted, e.g, a sunken ship, those lines then being pulled upwards to lift the submerged object. Winches may be provided to pull on the lines, conveniently mounted on a substantial size lifting platform, e.g. an iceberg.

Title: Temperature regulation in hydropneumatic suspension units
Inventor: GUESDON ALAIN
IPC: F16F9/08
Filed: 1985-02-15
Abstract: A unit for a vehicle suspension includes a volume of gas and a volume of liquid which are separated in sealed manner by a deformable membrane 16. A device is provided to regulate the temperature of the gas, said device comprising a temperature sensor 28 and a heating means (e.g. resistance 30) disposed in the volume of gas and connected to a regulator circuit 32 for maintaining the temperature of the gas substantially at the maximum value which it could reach during use of the suspension.

Title: A resonant element force sensor in a housing affording temperature and pressure compensation
Inventor: PYE JOHN ALBERT
IPC: G01L1/10
Filed: 1986-10-10
Abstract: A force sensor using a mechanically resonant element 13 includes two diaphragms 11, 12 connected by a rigid link 15 to prevent changes in pressure affecting the resonant element. The link may be a tubular member around the element 13 and this is connected to end caps 16, 17 on the diaphragms 11, 12. The element 13 is suggested at one end by a rigid arm 14. Optical fibres 18, 19, 20 provide pulsed and continuous light to excite the element 13 into resonance and to supply a detector 24 which measures the light modulation caused by the vibrating element 13. A processor 25 converts the detector signal into a value for the force F applied to the diaphragm and element 13. In another arrangement the arm 14 supports two resonant elements and the fibre bundles 18-20 are duplicated. A ball and socket connection between the or each element 13 and the end cap is also disclosed. <IMAGE>

Title: Analyzing two phase flow in pipes
Inventor: STEWART PETER ANTONY EABRY
IPC: G01N23/12
Filed: 1987-11-24
Abstract: A section of pipe carrying a material flow is x-rayed using e.g. a stereoscopic imaging system 1, 4, 5, 6, 7, 8 and the images stored, e.g. in a video frame store 9. The stored image data is operated on by an image processing system 10, 11, 12, 13 and information describing the density distribution of material flowing through the imaged section of the pipe is extracted. From this information the type of flow and the relative quantities of gas, liquid and solid is determined. The results are useful for controlling the operation of a pumping system supplying the material in order to cater, for example, for large quantities of gas in the flow. The results also find use in a fiscal metering system in an oil field, and in fuel and lubrication systems for gas turbine engines. <IMAGE>
Patent GB-2199086-A (GB)
Title: Dispenser pump
Inventor: WASS ANTHONY
IPC: B65D47/34
Filed: 1987-12-15
Abstract: A dispenser pump comprises a pump chamber (25) having a flexible wall (9) for altering the volume of the chamber (25). The flexible wall (9) is a polygonal pyramid, preferably five-sided, with facets (70) interrupted by respective cylindrical surface portions (71) inclined to the facet (70) so as to induce bending thereof when the wall (9) is flexed on actuation of the pump, thereby producing a force tending to restore the flexible wall (9) to its rest condition. An inoperative condition of the pump may be achieved by relative rotation of two body parts (1,15) of the pump about the axis of a slidable telescopic guide connection between the flexible wall (9) and a relatively fixed body part (15), a discharge nozzle (12) of the pump being out of register with an outlet port (29) of the pump in the inoperative condition. The flexible wall (9), an essentially rigid boundary portion (10) thereof, an essentially rigid guide member (6,8',80) that moves with it and the discharge nozzle (12) may be formed together as a one-piece integral part (1) of e.g. polypropylene. The construction enables a large pumping volume to be swept out in a relatively small diameter using only a small number of separate pump parts.

Title: Fastening load-carrying bars
Inventor: STONELAKE FRANK GEOFFREY
IPC: B60P7/15
Filed: 1988-10-28
Abstract: A removable load-carrying bar (1) for use in the restraint of loads, particularly in vehicles such as lorries. The end (6) of the bar (1) is adapted to be received by an opening (3) in a corresponding fixed perforated track (2). The presence of a releasable latch (8) adjacent the end (6) prevents the bar (1) from being disengaged from the associated track once inserted into position except either by pivotal movement of the bar (1) relative to the track (Fig 4) or by manually retracting the latch (8) by depression of latch control button (9). Disengagement of the bar (1) from its track can therefore be effected from the other end of the bar which is advantageous for a long bar. <IMAGE>
