Title: Methods and apparatus for reshaping hollow members
Inventor: FAULKENER MARTIN DAVID
IPC: B21D26/047
Filed: 1989-08-10
Abstract: A can reshaping apparatus includes a mould having two halves 18, 20 pivotally supported from a pivot post 12. A shuttle comprising a shaft 40 having upper and lower supports 48, 42 is slidable along the mould chamber axis to bring a can into and out of the chamber. When a can is brought into the chamber, the two mould halves 18, 20 are closed and this also imprisons the supports 48, 42 in the mould. A hydraulic clamp 54 acts to seal the flange of the can against a mould liner (26B, Fig. 6) of the mould. A mandrel 52 upstanding from a base 10 substantially fills the can but leaves a small gap. Compressed air is fed through openings 56 in the mandrel 52 into the gap to cause the can to expand to conform to the profile of the mould liner. The air is pressurised totally outside the can, and after reshaping of the can some of the pressurised air is recovered while still under pressure, for use in pressurising a subsequent can. The apparatus may be an automated can reshaping apparatus comprising eight can reshaping stations (4, Fig. 5) on a rotary turntable (2). A drive system of the rotary turntable is coupled to a piston (62, Fig. 8) supplying the pressurised air. The piston (62) moves in a cylinder (60) which is precharged with air from a source (68) of substantially constant pressure. <IMAGE>

Title: Method for three-dimensional clip checking for computer graphics
Inventor: PRIEM CURTIS
IPC: G06T15/30
Filed: 1989-09-21
Abstract: The method includes inputting a plurality of points comprising an image to be displayed, wherein each of the points is described by X, Y, Z and W world coordinates. The points are stored in the memory coupled to the CPU. The CPU executes a viewing algorithm which transforms the world coordinates for each point into view reference coordinates. The view reference coordinates have an origin at the viewpoint of the user, with the Z axis pointed outward in the direction of the display screen. Each of the points of the image are described by clipping bits X Right, X Left, Y, Top, Y Bottom, Z Back, and Z Front. The view reference coordinate system of the present invention permits the user to selectively enable/disable clipping quadrants in X, Y, Z and W space. The method determines the value of the clipping bits for all of the points (vertices) comprising the image. Using predefined combinational logic, the method evaluates the clipping bits and determines if the image is visible, hidden, or if it intersects at least one clipping plane. The method provides an efficient means for determining if a three dimensional image is to be displayed on a computer display system.

Title: Chemical sensor utilising a group of differently selective sensors
Inventor: WEIR DONALD JAMES
IPC: G01N27/12
Filed: 1990-12-05
Abstract: A device for detecting the presence of a chemical material, such as a gas, amongst a number of incident chemical materials comprises a group of sensors (1,2,3) having overlapping broadband selectivities in respect of the incident materials, so that each sensor responds, to a greater or smaller extent, to each of the materials. The sensor outputs are fed to a signal processor (5) which produces, for each material, a notional vector. These vectors are compared with stored reference vectors to identify the material under investigation. The responses to the various materials have a time-varying portion (x,y,z) and a portion of constant value. Certain materials may produce the same constant value, but different time-varying portions. The latter portions are therefore also taken into account in identifying the materials. A chromatographic layer may be provided over the sensors to distinguish between chemical species in the materials under test. <IMAGE>

Title: Compression of composite colour video signals
Inventor: STONE JONATHAN JAMES
IPC: H04N7/30
Filed: 1991-01-11
Abstract: To enable a digital composite colour video signal (NTSC or PAL) to be compressed directly, that is without dividing it into its components and compressing the components separately, the digital composite colour video signal is decorrelated, for example by spatial sub-band filtering or discrete cosine transform to form data sets, for example sub-bands, representing dc luminance information, ac luminance information and dc chrominance information. The data sets are then quantised in accordance with respective values such that the amount of quantisation of each of some of the data sets to which the dc luminance information and the dc chrominance information is at least predominantly confined is less than the average of the amounts of quantisation of the remaining data sets. At least some of the quantised data sets are then entropy encoded, e.g. run length or DPCM. <IMAGE>

Patent GB-2254637-A (GB)
Title: Sluice
Inventor: HARROP PAUL
IPC: E02B7/54
Filed: 1991-04-12
Abstract: In the draining of, e.g., fields it is known to employ low cost sluice gates to control such draining. However, low cost sluice gates are often of poor quality and do not seal successfully. The invention provides a sluice (10) in which a slideable plate (12) is resiliently biassed by a deformable guide member (16) against the open end of a duct (11) fitted with a peripheral seal (13). The resilient biassing ensures good sealing of the sluice, even when upstream pressure is low. When upstream pressure increases, the head of fluid acting on the plate (12) forces it into a more tightly sealing relationship with the seal (13). The advantage of the arrangement is that the sluice is of low cost yet provides good sealing ability. <IMAGE>
