Filed: 1986-09-05
Abstract: A process for upgrading a heavy hydrocarbon oil by involving a non-catalytic thermal hydrogenation zone and a hydrodemetallization zone wherein at least part of the hydrodemetallized product is subjected to atmospheric distillate and at least part of an atomospheric distillate obtained is recycled to the non-catalytic thermal hydrogenation zone.
Patent GB-2197097-A (GB)
Title: Data entry using dynamic word predication algorithm
Inventor: PICKERING ADRIAN
IPC: G06F17/30
Filed: 1986-11-04
Abstract: A method of data input comprises establishing a database or vocabulary of words and entering a word prefix. The word prefix is used to select all words from the vocabulary commencing with that prefix to form a sub-set for subsequent processing. The subsequent processing involves ordering the members of the sub-set in accordance with their potential relevance and truncating the ordered sub-set so as to identify a predetermined number of the most potentially relevant words. The truncated ordered sub-set is subsequently presented to enable the intended input word to be selected, if present, from among the presented words. The words are ordered in accordance with their recency of use, or their historical frequency of use, or preferably by a combination of the two.

Title: Semiconductor electro-optic device with controlled birefringence
Inventor: BENJAMIN JOHN DAVID
IPC: G02B26/02
Filed: 1987-05-01
Abstract: The device comprises a layer of semiconductor material (2), for example a silicon wafer, in which an array of transverse parallel slits (1) is formed. The device therefore exhibits birefringency to radiation having a wavelength more than twice the spacing of the slits and the birefringency effect is governed by controlling the free carrier density within the semiconductor. This may be effected by applying an electric potential at (6, 4) between respectively the body of the semiconductor layer and the surfaces (3) of the slit walls, which are doped (7) to a polarity opposite to that of the body of the layer. When such a device is assembled between two prisms a switchable polarizing beam-splitter is formed (Fig. 3). Other applications are switchable quarter- and half-wave plates, and shutters. <IMAGE>

Patent GB-2230566-A (GB)
Title: Piston engine
Inventor: RILETT JOHN WALTER
IPC: F01L21/04
Filed: 1989-04-14
Abstract: A piston engine has a cylinder 3 defining a bore closed at one end by a head 4, an inlet valve seat 23 cooperating with an inlet valve member 10, and a piston 24 reciprocable in the bore, the piston 24 having a pintle 32 upstanding from the centre of its crown to open the inlet valve member 10 as the piston 24 approaches the cylinder head 4. The cylinder head 4 includes, a metering chamber 6 having a bore axially aligned with the piston 24 and a metering piston 7 reciprocable in the motoring chamber 6. The inlet valve member 10 is resiliently supported in the crown of the motoring piston 7 so that during the forward (downward) stroke of the working piston 24 pressurised fluid from an inlet 18 flows from the metering chamber 6 into the cylinder 3 towards the end of the backward stroke the pintle lifts the inlet valve off the valve seat 33 to permit a charge of fluid to pass from the metering chamber into the cylinder bore to urge the piston forward again. At the end of the downward stroke an exhaust valve 26 in the working piston lifts off its seat 25 to allow a spring 33 to return the piston 24. A seal 16 carried by the inlet valve can engage a seat 17 on the motoring piston so that a metered quantity of pressurised fluid is displaced by the metering piston into the working cylinder 3 during each forward stroke. <IMAGE>

Title: Still video camera
Inventor: AOKI HARUMI
IPC: H04N5/77
Filed: 1989-10-03
Abstract: Parameters to be set on a camera, e.g. photographic mode (self timer, single or multiple shot), record/playback, white balance, date/time, are selected by operation of one or other of switches 18, 19, the selection being shown by flashing of a corresponding area in display 15, and adjustment of the selected parameters by operation of up down switches 17a, 17b or switch 19, thereby reducing the necessary number of switches. Switches 17 are also used to set an EV number on depression of a button 21. In a still video camera having a playback function, a change-over switch automatically changes the operating mode of the camera from a record mode to a playback mode when a monitoring adapter is connected to the camera, further reducing the number of actuating members that are needed to control the camera. In addition, the camera is designed to minimize the waste of electrical power by inhibiting the operation playback mode until the camera is instructed to begin operating.

Title: Integrated map and solar compass
Inventor: COURTNEY WILLIAM ALEXANDER
IPC: G01C17/34
Filed: 1990-05-23
Abstract: A solar compass which consists of a circle similar to a clock face but calibrated so that the circumference represents 24 hours instead of the normal 12 hours. This is superimposed onto a map or map cover so that midnight faces the North end of the map. Local time is noted (with a correction for summer time if necessary). By lining the centre of the circle, the value for the local time as read on the clock type face and the current direction of the sun the map is correctly aligned so that North on the map is in the direction of true North. This method of orienting a map is quicker and simpler than using a magnetic compass. It is only viable when the sun is visible, but adds no costs to the map manufacturing process. <IMAGE>

Patent GB-2251152-A (GB)
Title: Noise reduction processing means for video signals
Inventor: THOMSON RICHARD CHARLES
IPC: H04N5/217
Filed: 1990-12-20
Abstract: Image intensified T.V. cameras are prone to produce noisy pictures, the noise being in the form of a speckle pattern of bright white dots above the background picture. To reduce this noise framestores A store successive parts of three frames of the camera's video signal, and a logical output selection unit 2 arbitrates between the framestore outputs to produce a reduced noise output. If the noise of a pixel in the central frame is increased significantly compared to that in the first frame, the output of the third frame for that pixel is used to arbitrate between the two, for example, by selecting as the output that of the first frame if it is found that the output of the third frame is nearer to that of the first frame than to the second. Isolated noise specks are thereby reduced without the problems of motion smear. <IMAGE>

Title: Microcomputer key scanning
Inventor: KWON SUN-DON
IPC: G06F3/023
Filed: 1991-10-25
Abstract: A key scan method includes a step of designating the input/output modes of a bilateral port (or equivalent) by a data direction register DDR in a microcomputer 10 which includes an input/output bilateral port PB and an input-only unilateral port PA, so as to prevent circuit shorts when more than one key are pushed. The columns of keypad 20 are scanned in turn by a single 1 in DDR which selects output mode for the corresponding bit position of port PB. If the scanned column has any key actuated, a O appears at port PA, and the inputs at PA are bit-wise ANDed into a memory MA and DDR is bit-wise ORed into a memory MB. After scanning is complete, more than one 0 in MA or more than one 1 in MB indicates multiple-keying error, Otherwise, the key identify is calculated from MA, MB. <IMAGE>

Title: Improvements in or relating to tufting machinery
Inventor: CROSSLEY PHILLIP HAROLD
IPC: D05C15/12
Filed: 1992-03-30
Abstract: Improved pattern definition in tufted fabrics produced on dual sliding bar machines is achieved by optimising needle gauge potential, the sets of needles (24, 25) provided on the respective needle bars (26, 27) being more closely spaced in the direction of backing fabric movement than in conventional arrangements and the hook/loopers (22, 23) being of such throat length as to be cooperable with the needles (24, 25) of either needle bar (26, 27). Thus a needle on either bar can cooperate with immediately adjacent loopers or hooks instead of having to be displaced between alternate loopers or hooks allowing a reduction in the pitch of needle bar displacement. <IMAGE>
