Title: Gas blast interrupters
Inventor: STEWART JOHN STANLEY
IPC: H01H33/70
Filed: 1983-06-23
Abstract: In a contacts closed position of the interrupter, one contact 20 engages a further contact 21 and passes substantially sealingly through an insulating orifice 25 in a tubular housing 24 which surrounds the contact 21 and through a further insulating orifice 27 in a tubular guide 26 which surrounds the housing 24. Upon initial contact separation formations 20a on the contact 20 disengage from contact formations 22 on the contact 21 and subsequently also disengage from a metal probe 23, thereby drawing an arc between the contact 20 and the probe. Pressurised gas is supplied to an annular chamber 28 defined between the housing 24 and the guide 26 so that, when upon further contact opening the contact 20 passes out of the orifice 25, the pressurised gas is able to flow out of the chamber 28 and through the orifice 25 to cool and de-ionise the arc. Upon still further contact opening, the contact 20 also passes out of the orifice 27, thereby permitting the pressurised gas to flow therethrough out of the chamber 28 in the opposite direction to the flow of gas through orifice 25. <IMAGE>

Title: A dart flight stem
Inventor: KOYCE JOHN PATRICK
IPC: F42B6/00
Filed: 1984-04-06
Abstract: A dart flight stem intended to be furnished with a flight comprising four planar vanes radiating from a longitudinal axis of the flight, has, instead of the conventional form in which the stem has two longitudinal intersecting slots extending from its rear end and dividing the rear of the stem into four adjacent portions, a form corresponding to that which would be produced by removal of two diagonally opposite said portions from such a conventional stem to leave diagonally opposed portions 18 spaced apart by V-section channels 23. This configuration avoids damage to the flight from the point of a subsequently thrown dart striking the flight, as such a point readily slips out of the V-section channels 23. The channels 23 terminate at their forward ends in sloping flanks which further assist in deflecting the point of a following dart. <IMAGE>

Title: A horizontal plate freezer
Inventor: FENNER FRANK RICHARD
IPC: F25D31/00
Filed: 1987-02-06
Abstract: A horizontal plate freezer has a stack of freezer plates comprising an upper group and a lower group of plates. An upper pressure frame 12 overlies the upper group and a lower pressure frame 11 lies between the groups. Hydraulic piston and cylinder arrangments 22, 23 engage the upper frame 12 to lift it sufficiently to move the plates of the upper group relative to each other to an open place spacing in which products can be loaded and unloaded in the space between adjacent plates. In the first condition with all plates in closed spacing for freezing product, the stack has a first height, which will increase to accommodate the opening of the upper group of plates to the open spacing condition. Hydraulic piston and cylinder arrangements housed in guides 17, 18 engage the lower frame 11 to move the plates of the lower group to open space condition and close the upper group to closed spacing, in so doing the lower frame 11 raising the lowermost plate of the lower group from its initial position and closing the upper group to closed spacing. Raising the lower frame does not increase the stack height. Lowering of the lower frame will return the plates of the lower group to the intitial condition in closed spacing and lowering the upper frame returns the upper group to closed spacing, and the stack height to the first height. <IMAGE>

Title: Ultrasonic shape assessment device for non-spherical particles in solution
Inventor: TRENCHARD PAUL MALCOLM
IPC: G01N15/14
Filed: 1988-07-08
Abstract: An annular ultrasonic transducer 1 is compressed against a transparent plastic pack containing non-spherical particles e.g. platelets in solution. The opposite pack surface 5 is maintained flat and normal to the propagated cylindrically-shaped ultrasound beam, so that reversed (180 DEG ) reflection occurs. This arrangement causes counterflow of particles within the core fluid retained central to the cylindrical ultrasound field, and enables light transmission/scattering measurements to be made in the core axis without obstructing the ultrasound field. The core counterflow causes orientation of suspended non-spherical particles. Light transmission/scattering relative to particle flow rate, within the core, allows indirect assessment of the degree of particle non-sphericity, and its rate of change with time. The latter is particularly applicable to monitoring particle shape transformation during the storage of certain types of blood cells. <IMAGE>

Title: Liquid crystal display
Inventor: WILTSHIRE MICHAEL CHARLES KEOG
IPC: G02F1/139
Filed: 1988-07-20
Abstract: A liquid crystal display comprises a body of a nematic liquid crystal host material (1) which contains a pleochroic fluorescent dye and which is supertwisted. Parameters of the display are selected such that the display has a transmission wavelength spectrum which encompasses the emission spectrum of the fluorescent dye. In a backlit mode, the display operates in transmission and the light from an electroluminescent panel (11) excites the fluorescent dye in the liquid crystal. In high ambient light levels, the display operates in a reflective mode and the fluorescence is excited by ambient blue or ultraviolet light. The absorption and the fluorescence of the dye are anisotropic, so that switched segments appear dark. In unswitched regions of the display, however, the fluorescence is excited and gives a bright background to the display. Hence, the effect of the fluorophor is to improve the brightness of the display.
