Title: Waveguide apparatus
Inventor: TODD MURRAY JAMES
IPC: H01P1/06
Filed: 1988-05-21
Abstract: Waveguide apparatus includes a rotating joint 5 across which microwave power is transmitted. One microwave signal is transmitted via ports 6 and 7 in the TM01 mode and another signal at a different frequency is transmitted across the joint 5 in the TE10 mode. The transition from a TE10 mode to the TE01 mode is achieved by applying a signal to the E-plane port of a Magic-T 10 and arranging the outputs of the Magic-T 10 to be adjacent one another. The outputs are then applied via a short taper and an iris to a resonant cavity at the joint 5. <IMAGE>

Title: Method and apparatus for optimized depth cueing using short vectors
Inventor: MALACHOWSKY CHRIS
IPC: G09G1/06
Filed: 1989-10-23
Abstract: A computer graphics system which determines displayed intensities of points representing line segments (e.g. CD) on a raster computer output display which intensities would ideally vary in general in accordance with the depth of each point to be represented, comprising apparatus for determining the ideal intensities of each end point C and D of such a line segment to be displayed, apparatus for averaging said intensities of the two end points, and apparatus whereby all points describing the line segment are displayed at the same intensity equal to the average value of the intensities of the two end points. The effect of the removal of continuously varying intensity depth cueing is minimised since curves B C D F on computer graphics displays tend to be definable as a series of short line segment vectors BC, CD, DF. A long segment 30 is initially broken down into smaller portions MN etc. each of which will have a uniform intensity point. <IMAGE>

Patent GB-2233541-A (GB)
Title: Carcass stripping
Inventor: WILKES ANTHONY JAMES
IPC: A22B5/16
Filed: 1990-07-12
Abstract: Carcass-stripping apparatus 10 uses jaws at 14 to grip the poll region 18 of a pelt 16 on an inverted hung carcass 12. The jaws 14 are then driven down by an actuator 22 to strip the belly. Rollers 26, 28 on the jaws are then driven to rotate and draw the remainder of the pelt from the carcass. During drawing, tension exists only in the part of the pelt between the jaws and the carcass. Appropriate positioning of the jaws 14 at the lower end of its stroke can ensure that the delicate belly portion of the pelt is through the nip of the rollers 26, 28 before the larger forces required to strip the hind legs are applied to the pelt. <IMAGE>
Patent GB-2237664-A (GB)
Title: Safety valve arrangement
Inventor: DU PLESSIS JACOBUS NICOLAAS
IPC: F16K17/32
Filed: 1990-10-05
Abstract: A self-actuating safety cut-off valve arrangement (10) includes a main valve housing (14) having an inlet (16) and an outlet (18) for connection in a high pressure fluid line. A valve member (24) is carried slidably within the main valve housing (14) and is movable from an open position, in which it allows the passage of fluid through the fluid line, to a closed position. An auxiliary inlet port (60) is formed in the housing (28) and communicates with one end of a feedback line (64). The opposite end of the feedback line (64) communicates, via a 3-way pilot valve (12), with the fluid line downstream of the valve member (24). An orifice plate (106) located downstream of the valve member (24) is connected to the pilot valve (12) by linkage (108). A lowering in pressure in the fluid line, generally caused by a downstream rupture or breakage, moves the orifice plate (106) to switch the pilot valve (12), and thus vent the feedback line (64) to atmosphere. The main valve member (24) is arranged to move to the closed position in response to the drop in pressure it experiences via the feedback line (64). <IMAGE>

Title: Graphics accelerator rendering outlines using parallel processing
Inventor: NEAVE JOHN WALTER
IPC: G06T17/00
Filed: 1991-01-09
Abstract: A graphics accelerator system which provides improved speed in displaying the outline of a convex graphical primitive. A set of n boundary offsets is added onto each of the m points in the set of pixels to be outlined. The resulting n x m calculated pixel positions will contain many duplications; but only those of the resulting calculated pixel positions which have been duplicated fewer than n times are considered to be boundary pixels. (For a dense set of imaged pixels, this constraint will filter out the pixels in the interior.) This calculation is performed by a parallel graphics processor, and is parallelized over the set of pixels in the graphical primitive rather than over the number of offsets. <IMAGE>
