Title: Hydraulic Lifting Circuits
IPC: F15B11/08
Filed: 1979-09-20
Abstract: A hydraulic system for raising and lowering loads includes a pump (16) which is operable, preferably by an electric motor, to deliver fluid from a reservoir (18) to a remote jack (10) through a conduit (20) and a solenoid- operated check-valve (26) of an assembly (24) integral with jack (10) to effect raising of a load by the jack (10). The pump (16) is adapted to allow fluid to pass therethrough in the opposite sense and the system is arranged such that upon actuation of valve (26) fluid is returned from the jack (10) through a flow regulator (27) of assembly (24) and thence through the conduit (20) and the pump (16) to the reservoir (18) in order to lower the load. <IMAGE>

Title: Thermally insulated heat accumulator
IPC: F28D20/02
Filed: 1979-12-12
Abstract: A heat accumulator for use in a space heating or hot water supply system comprises an insulated container containing a heat storage medium, e.g. water or wax, and having a radiant heat reflecting lining or coating. As shown, the container 1 comprises a cylinder 2 formed from a series of rigid urethane foam segments, a top 3 and a bottom 4 of the same material, and a watertight liner 15 of polished aluminised foil.

Title: Adhesive metering device
IPC: B05C1/08
Filed: 1980-03-04
Abstract: A glue applicator has an elongate shoe 10 floatingly mounted alongside of and urged toward a glue applicator roll 101 by a fluid controlled biasing means 40. A longitudinally extending depression 22 in the shoe 10 is substantially closed by the glue roll 101 to define a glue cavity 22 to which glue is fed by a positive displacement pump via line 406. The shoe 10 is mounted so that the downstream end of the shoe 10 is movable away from the glue roll 101 automatically as required to permit glue to exit from the cavity 22 at the same rate it is supplied thereto. This provides what is effectively a self-adjusting nozzle or metering slot 51 extending the full length of the shoe 10 and through which glue is forced from the cavity 22 to form a thin layer of uniform thickness on the outside of the glue roll 101. <IMAGE>

Title: Hydraulic directional control valve
IPC: F15B13/043
Filed: 1980-03-17
Abstract: In a hydraulically operated directional control valve of open- centre type the spool (12) is remotely operated electro-hydraulically by valves (36,37) controlling flow of pressurized liquid from a pump connection port (23) to drain. The pressurized liquid acting in chambers (13,13A) on the ends of the spool. In order that an adequate operating pressure may always be available, the spool (12) is adapted upon movement away from the neutral position to restrict the flow path between the pump connection port (23) and the tank connection port (25) rapidly enough to ensure that the pressure produced by the pump increases to the value required for a firmly controlled displacement of the spool (12) throughout the displacement range before the opening of the flow path between the pump connection port (23) and the load connection port (26,27) begins. <IMAGE>

Title: Vacuum apparatus for liquid extraction of solids
IPC: B01D29/09
Filed: 1980-07-24
Abstract: An intermittently operating device for extracting or washing components from solids lying on a pervious band 24 contained within a chamber 28, 2 that is sealed by means of a hinged cover 1 that can be moved vertically by means 21. A batch of solids in slurry form is introduced from agitation tank 17 into the chamber where the slurry is dewatered by means of a vacuum pump 20 connected through vacuum receivers 29, 30 via line 34 to the bottom sealed chamber 2 that supports the pervious band. A number of charges of liquid with various concentrations of solute which have been obtained from the extraction of the previous batch of solids are consecutively drawn under vacuum into the chamber containing the solids and sucked through the solids and the pervious band. The liquids with differing concentrations of solute are then removed as described to separate vacuum chambers 29, 30, the liquid with the strongest solute concentration being first pumped from the system via line 37 to a storage tank. The cover 1 is then raised and the solids are then discharged from the chamber by means of pervious band 24 driven by a motor 5. The sequence of opening and closing the various valves indicated is described in detail. <IMAGE>

Patent GB-2082765-A (GB)
Title: Optical/pressure switch
IPC: G01L1/16
Filed: 1980-08-21
Abstract: A force or pressure sensitive switch includes a piezo-electric element (18) wherein changes in applied pressure or force produce corresponding changes in electrical potential developed across the element. This potential, being applied to the electrodes of a liquid crystal device (14), varies the light transmissivity thereof in accordance with that potential above a certain threshold level. Light, passed from a light source (10) via optical fibres (11-12-13) through the device (14), is reflected by a mirror (15) back through the device and then travels via optical fibres (13, 12, 16) to a light detector (17). Thus changes in the light reaching the detector depend on changes in the force or pressure being monitored. Alternatively, the fibres coupled to the light source and the detector are on opposite sides of the liquid crystal device. One application of such a switch is as the vortex frequency sensing means in a vortex flow meter. <IMAGE>

Patent GB-2094280-A (GB)
Title: Photochemical vapour deposition of oxides
IPC: H01L21/225
Filed: 1981-03-06
Abstract: The specification discloses a low temperature process for depositing oxide layers on a substrate by photochemical vapor deposition, by exposing the substrate to a selected vapor phase reactant in the presence of photochemically generated neutral (un-ionized) oxygen atoms. The oxygen atoms react with the vapor phase reactant to form the desired oxide, which deposits as a layer on the substrate. The use of photochemically generated neutral oxygen atoms avoids damage to the substrate due to charge bombardment or radiation bombardment of the substrate. The deposited oxide layer may optionally incorporate a selected dopant material in order to modify the physical, electrical, or optical characteristics of the oxide layer.
