Inventor: BLACKBOURNE CEDRIC
IPC: B28B7/36
Filed: 1988-05-25
Abstract: A method of and apparatus for moulding is provided wherein a plug (17) upstanding from a base (15) has a wall- bounding face of a mould cavity defined by a surface of a layer of lining material (21) which is sufficiently strong to resist deformation under hydraulic forces applied by the fluid casting material, but sufficiently yielding to allow separation of a cast article from the plug (17) without significant increase in separation force. <IMAGE>

Title: Bath plug release mechanism
Inventor: JOHNSON ERROL PHILMORE
IPC: E03C1/242
Filed: 1988-09-15
Abstract: A bath plug release mechanism comprises a vessel 1 connectable to bath plug P and locatable below bath overflow 3 and having a valve element 4 mounted above an aperture in its base, and a duct 2 surrounding the vessel and provided with spring-loaded ball retaining members 6b which are engageable with lugs 6a on the exterior surface of the vessel, the arrangement being such that when the vessel is filled with water from the overflow to an extent such that its weight overcomes the restraining force of the spring-loaded ball retaining members, the vessel descends thereby raising the bath plug and on reaching the bottom of the duct, valve element 4 lifts to allow discharge of water. Overfilling of the bath is thereby prevented. <IMAGE>
Patent GB-2210578-A (GB)
Title: Injection moulding hollow articles
Inventor: SAYER MATTHEW EMMETT
IPC: B29C45/34
Filed: 1988-09-23
Abstract: An injection moulded plastics article is produced by introducing a stream of molten plastics material from an injection moulding machine cylinder into an article forming mould space (13). Pressurised gas is supplied into the interior of the molten plastics material to form a gas containing cavity (25) therein. The plastics material is then allowed to solidify and cool sufficiently so that the article can itself sustain the form dictated by the mould surface. The cavity is vented to reduce the pressure within the cavity to ambient pressure prior to opening of the mould. The step of venting the cavity is achieved by providing at at least one position which is separate from the plastics inlet and the gas inlet a vent passage (30) in the mould open at its inner end to a part of the interior of the mould at which the gas containing cavity (25) is formed, and a retractable closure (31) for opening and closing the vent passage at its inner end, maintaining the closure in its closed position during the forming of the article whereby the cavity wall is formed over the inner end of the vent passage and the closure therefor, and subsequently retracting the closure to allow the creation of a vent opening in the cavity wall in the area of the inner end of the vent passage through which vent opening gas from the cavity passes into the vent passage. Apparatus for carrying out the above process is also described.

IPC: C02F1/00
Filed: 1988-11-22
Abstract: In an electrochemical cell for decomposition of organic waste liquids having an anode compartment 16 and a cathode compartment 18 separated by a porous pot 20, the anode 26 is driven by a shaft 28 having an axial passage 32 extending from an upper inlet 34 in the vicinity of the liquid level to a lower outlet adjacent a turbine 36. The rotating anode 26 produces Taylor vortices in annular space 29 and liquid is drawn from layer 50 through passage 32 and emerges to contact the anode 26. In one use, organic solvent such as tributyl phosphate/odourless kerosene is destroyed. Fresh solvent is added through an inlet. A helical cooler 44 may also be provided. <IMAGE>

Patent GB-2237206-A (GB)
Title: Adhesive sheet
Inventor: WARD WILLIAM JOHN
IPC: A61F13/00
Filed: 1990-10-30
Abstract: An adhesive sheet material for use on the skin comprises a backing layer which has upon at least a portion of one surface a pressure sensitive adhesive layer. A removable release liner covers the adhesive layer and a support layer is attached to the backing layer on the surface remote from the pressure sensitive adhesive layer. The stripping load required to separate the release liner from the adhesive layer is greater than the stripping load required to separate the support layer from the backing layer. As the release liner is stiffer than the support layer then the release liner can be removed from the adhesive without disturbing the support layer. The support layer is conformable enough to remain attached to the sheet when adhered to the skin. Adhesive sheets in the form of ostomy flanges and IV dressings are described.

Title: Inrush current reduction in ir lamp hot plates
Inventor: HIGGINS GEORGE ANTHONY
IPC: F24C7/04
Filed: 1990-11-19
Abstract: A radiant electric heater has one or more infra-red lamps (22, 24) having a relatively high temperature coefficient of resistance. To reduce the inrush current when the lamps are first energized, a series resistance coil (54) is provided together with circuitry (64, 66, 68, 70) to bypass the series resistance after a short time interval. Because the energy dissipated in the coil is relatively limited, it can be concealed beneath a peripheral insulating wall (18) of the heater.

Title: Spatial transformation of video images
Inventor: STARR MATTHEW RAYMOND
IPC: G06T3/00
Filed: 1991-04-11
Abstract: A digital video effects system, that can be used as a subsystem of a digital video system, performs real-time, anti-aliased spatial transforms of input video i.e. it provides an output signal where the picture is a spatially distorted version of the input picture. Any defined area of the input video frame can be placed anywhere in the output frame with independent changes in size and direction along either axis, by manipulation first vertically and then horizontally. For vertical transformation a vertical sequence controller 14 is operative to select and order regions to which transformation parameters are applied from a vertical parameter controller 18. Transformation is undertaken in a vertical spatial interpolator 30. The intermediate vertically transformed image is then similarly horizontally transformed in a horizontal spatial interpolator 32 under control of a sequence controller 22 and parameter controller 26. <IMAGE>

Title: Extraction from spatially coherent noise of a time-variable signal of finite spatial extension
Inventor: FLAMENT BRUNO
IPC: H03H21/00
Filed: 1993-11-26
Abstract: The required signal is subject to q spatially coherent additive noises, and the resulting signal is detected by an array of N sensors or transducers, N being equal to or greater than 3 and q being lower than N. The signals are extracted by acquiring unprocessed signals on the output of each sensor, band-pass filtering the signals to restrict to the frequency band of the useful signals, and of digitizing the filtered signals. Spatial prediction error signals of the noise, are then calculated by a process in which one of the N sensors is selected, the remaining N-1 sensors are distributed into groups of q sensors (the same sensor can belong to more than one group) and, if the signals of a group are independent, they are used to construct a prediction error signal in a specified manner. The prediction error signals are then analyzed and used to recover the required signal from the noise. The process may be applied to the field of magnetic detection. <IMAGE>
