Patent GB-2183317-A (GB)
Title: Apparatus for drying stenter held material
Inventor: PERKIN DR ROBERT MELSON
IPC: F26B23/08
Filed: 1985-11-12
Abstract: Web material 12 undergoing process treatments such as drying is generally held in lateral tension by metallic stenter pins 17 which are themselves mounted on metallic rails 18 and 19: the use of R.F. heating is therefore precluded due to the possibility of high voltage flashovers from the metallic components. This specification discloses an apparatus which allows stenter held material to be dried by an R.F. field originating from electrodes 10 and 11 by having electrically conductive screens 21 positioned to exclude substantially all the r.f. field from the stenter pins and rails. <IMAGE>

Title: Imaging arrangement
Inventor: YOUNGS ERIC GEOFFREY DUNLOP
IPC: H04N3/09
Filed: 1986-02-02
Abstract: An imaging arrangement combines a thermal imager 15 with a laser imager 7, 11 to enable several correlated pictures to be produced which show different properties of the same field of view. A common scanning device 6 is used to scan each pixel in the field of view in a raster-like pattern, and for each pixel data can be derived representing thermal content, range, optical reflectivity and velocity. The last three properties are obtained by coupling an optical interferometer 11 to the scanning device 6 which generates the picture representing the thermal content.

Title: Process for the production of bitumen
Inventor: FABB TERENCE REGINALD JOHN
IPC: C10C3/04
Filed: 1987-03-12
Abstract: Hydrocarbon feedstocks derived from crude oil and containing at least 1% by wt of a component, which boils below 450 DEG C are blown with a mixture of gas containing free oxygen and an inert stripping gas or vapour, which may be steam. This mitigates the problems associated with bitumens derived from such feedstock, including the adverse effects upon the ageing properties and fume evolution of the bitumen. The process is carried out at 210-280 DEG C and uses 250-1100m<3> of stripping gas per tonne of feedstock.

Title: Tile stacking apparatus
Inventor: POWEL WILLIAM ROY
IPC: B65G57/32
Filed: 1987-12-03
Abstract: Articles, for example concrete roofing tiles, arriving in a stream on an in-feed conveyor (2) are stacked at first and second stacking stations (3,4) each having elevators (5,6 Fig 2) and located one behind another along the length of the conveyor. As articles arrive in the stacking station (3) they are stopped by a stopper (13) and an elevator (5,6) is then operated to lift the article to make room for the next article to arrive and so on until a stack of the required size is formed within the stacking station (3). The next article is lifted from the conveyor in the upstream stacking station (4) and pushed into the downstream stacking station (3) simultaneously with ejection of the completed stack by means of a pusher apparatus (9). The cycle then repeats. <IMAGE>

Title: Greenhouse utilizing insulation and reflected sunlight
Inventor: OGLE JOHN HADLOW
IPC: A01G7/04
Filed: 1988-03-01
Abstract: A building for horticultural use which incorporates glazing on one face only, the Southern face for Northern latitudes. The remainder of the structure is of high thermal mass and/or high thermal insulation to minimise heat loss and maximise thermal storage. A system of moveable insulation panels over the low level glazing are arranged to increase solar collection when open and to insulate the low level glazing when closed. A system of moveable insulated panels form a reflective ceiling, which is raised during periods of sunlight and lowered at other times to create an insulated ceiling and to isolate the glazing. The system may incorporate low level up-lighters for use when the insulation panels are closed reflecting artificial light from the ceiling onto the growing area. The system may incorporate heat storage in the form of a rock bed or by means of phase change eutectic salts. <IMAGE>

Title: Liquid container
Inventor: SHARPLES LEONARD
IPC: B67D1/04
Filed: 1988-08-05
Abstract: A liquid container (10) comprises an outer housing (11), and an elastomeric bag (12) arranged in the housing to hold a charge of liquid. The bag is capable of being expanded as it is filled with liquid until at least part of its outer surface engages with the inner wall of the housing. A dispenser outlet permits dispensing of the liquid product from the bag, and pressurised gas, or a source of pressurised gas, is introduced into the interior of the housing (11) so as to apply a compressive force to the bag such that, upon operation of the dispenser outlet, the liquid can be discharged from the bag under the action of the pressurised gas. The elasticity of the bag may be sufficient to permit its expansion during filling with liquid, but if additional pumping action is required, greater elasticity may be provided in the bag so that bag contraction also contributes to the pumping action exerted on the liquid during dispensing. <IMAGE>

Patent GB-2216439-A (GB)
Title: Centrifuge drum with whirl discharge chambers
Inventor: BRUNING DIPL-ING PAUL
IPC: B04B11/02
Filed: 1989-03-03
Abstract: From the solids space (4) in the centrifuge drum (1) channels (3) lead to an inner chamber (11) in the centrifuge drum (1), from which the solids are led away by means of a paring member (12). With each of the channels (3) a whirl discharge chamber (5) is associated, having an outlet (9) which opens into the inner chamber (11). A discharge whirl is created at the outlets (9), which opposes increasing resistance to the throughput. The whirl created becomes less with increasing viscosity of the solids flowing out. If the viscosity of the solids increases, the amount of solid flowing out via the outlets (9) also increases and thus leads to a reduction in the vismsity. The reverse effect occurs with decreasing viscosity. The whirl discharge chambers (5) thereby lead to automatic regulation of the concentration of solids. 
<??>Various embodiments disclose provision of more than one whirl. discharge chamber in series for each channel (3); and throttling arrangements to enhance the whirl effect by throttling the output through each outlet (9).

Patent GB-2216841-A (GB)
Title: Moulding processes
Inventor: COOPER ROYSTON BARRY
IPC: B29C45/00
Filed: 1989-03-15
Abstract: Rigid mouldings, eg. kitchen sinks, having a wall thickness generally not exceeding approximately 0.4in (10mm) are produced by a process in which pre-heated and de-gassed curable resin composition, which sets within 60 minutes, is supplied under at least 4 psi (280g/cm<2>) pressure to fill a hotter mould and thereafter until the composition in the mould has set so as to compensate for shrinkage. The composition temperature is controlled in the mould to maintain a substantially linear temperature gradient in the composition increasing from its entry into the mould for the composition to set progressively through the mould back to the entry. Preferably the composition comprises an epoxide resin, an anhydride hardener and a mineral filler, and the temperature gradient is approximately 10 DEG C. Typically using a solid system composition maximum pre-heated mould temperature is 170 DEG C, the composition is supplied at 90-120 DEG C at 15 psi (1050g/cm<2>) and the moulding is removed in under 30 minutes for heat treatment. Using a liquid system composition maximum pre-heated mould temperature is typically 120-160 DEG C and composition is supplied at about 50 DEG C.
