Patent GB-2075936-A (GB)
Title: Air cushion vehicle cushion pressure regulation
IPC: B60V1/16
Filed: 1980-05-14
Abstract: A gas-cushion vehicle has means (20 or 20a) for reducing dynamic variations in cushion gas pressure. The means comprise a gas-flow outlet connection between a space (3a) occupied by cushion gas and the atmosphere, and flexible wall member (10) of inflatable form disposed within the connection and operable to allow cushion gas to escape as cushion pressure tends to increase, and to impede such escape as cushion pressure tends to decrease. The flexible wall member (10) provides a barrier maintaining a pressure differential between the cushion space and the atmosphere. Dynamic variations in cushion pressure will alter this pressure differential and the resistance to the escape of cushion gas offered by the wall member will then alter accordingly. Pressure in wall member (10) may be automatically controlled according to cushion pressure, pitch/ heave acceleration, etc. <IMAGE>

IPC: C23C16/442
Filed: 1981-09-29
Abstract: Processes and apparatus for coating inert particles, e.g. alumina, with tantalum by chemical vapour deposition in a fluidised bed of the particles (3). Tantalum pentachloride is produced immediately prior to introduction thereof into the bed chamber (3) by reacting hydrogen chloride gas with tantalum metal powder in an adjacent reaction chamber (1).

Title: Forage harvesters
IPC: A01D34/43
Filed: 1982-01-07
Abstract: A forage harvester is provided with a pressure means such as a forward roller 5, which holds cut forage on the ground as the forage harvester is drawn over it. A flail rotor 3 within the forage harvester then lifts up the cut forage, which is held on the ground by the roller 5, and co-operates with cutting plates 6 to carry out a chopping action. In this way, satisfactory chopping can be achieved with a relatively simple cutting mechanism. The pressure means may alternatively be a plate. <IMAGE>

Title: Apparatus for Measuring Attenuation in an Optical Fibre
IPC: G01M11/00
Filed: 1982-02-02
Abstract: The apparatus comprises a section 12 which generates and transmits optical pulses to the fibre 11, a beam splitter 14 and photodetection, amplification and signal processing devices 15. The detector 15 contains an integrator circuit 40a, connected downstream from a photodetector 21a, and which supplies an output signal which is the time-integral of one electrical signal, from the photodetector 21a. The pass-band of the integrator circuit 40a may be changed by altering its reactive component values, with consequent optimisation of the opposing factors of maximum inspectable fibre length and spatial resolution. The use of two similar circuits 16a, 16b, with one photodetector 21a irradiated by backscattered light from the fibre 11 and the other 21b shielded from light, enables the subtraction of spurious signals by a differential amplifier 20. A logarithmic amplifier 34 enables a linear output to be generated at terminal 37. <IMAGE>

Patent GB-2131723-A (GB)
Title: Painting plastics components
Inventor: HERRIOTT CHARLES EDWARD
IPC: C25D13/22
Filed: 1982-12-17
Abstract: A plastics component is painted by making at least its surface conductive (by loading conductive powder therein or applying conductive paint), applying a layer of paint by cathodic electro-coating, and applying further coats of paint to the electro-coated layer. By applying an electro-coated layer, the rejection rate of the components is reduced, since the electro-coated layer prevents the formation of blisters in the enamel layer which would otherwise occur due to solvent absorbed in the plastics material coming to the surface on heating the component to cure the enamel layer. An article (e.g. a motor vehicle) having both plastics and metal components can be painted by making the surfaces of the plastics components conductive, assembling the plastics and metallic components, passing the assembled components through a phosphating bath, applying a coat of paint to the components by cathodic electro-coating, and applying further layers of paint to the electro-coating layer. Thus the same painting process can be used for both the plastics and metal components.

Title: Improvements in or relating to hand-controlled electrically-powered appliances
Inventor: TRELFORD ALAN
IPC: A01D34/68
Filed: 1983-03-04
Abstract: A hand-controlled electrically-powered appliance has a handle assembly which, as a safety measure, requires the user to have both hands on the handle 1 to bring the electric motor into operation. The handle assembly incorporates a manually-operable lever 16 which controls energization of the motor and a slide 17 which can interlock mechanically with the lever to prevent accidental operation thereof. The slide 17 has a manually-engageable surface 34 by which the slide can be released from the lever 16 to allow the motor to be energized but the surface 34 is sufficiently spaced from the lever 16 to prevent single-handed operation of both controls. <IMAGE>

Title: Filing cabinet for suspended drawings
Inventor: MITCHELL HAROLD VICTOR
IPC: B42F15/06
Filed: 1983-03-23
Abstract: Suspended drawings etc. are stored in a filing cabinet having a front wall (3) pivoted about a horizontal axis (12) which extends intermediate the upper and lower edges of the front wall. Preferably, the pivot axis lies closer to the mid point of the front wall than to the lower edge, and lies in a vertical plane inwardly of the vertical plane of the front wall. The positioning of the axis (12) is such that, when the front wall is fully loaded with sheets and is in its open position, the weight of these sheets on the front wall which bias the front wall to its open position, is minimised. Thereby a minimum force is required from the operator to move the front wall to its closed position. A spring may bias the front wall (3) towards the closed position. <IMAGE>
