Patent GB-2196642-A (GB)
Title: Agglomerated solid fuel briquettes
Inventor: WRIGHT WILLIAM RICHARD
IPC: C10L5/14
Filed: 1986-10-22
Abstract: Shaped briquettes for use as a smokeless or smokey combustible solid fuel are manufactured by firstly compressing a mix of agglomerated solid fuel particles and a binding agent such as resin and starch or a lignosulphonate to produce "green" briquettes of low compression strength. The green briquettes are then treated in a microwave oven at elevated temperature (e.g. 120 DEG C-300 DEG C) for a short period of time sufficient to bring about partial or complete hardening and curing of the green briquettes. There is also disclosed apparatus for such manufacture.

Title: Extended nip press
Inventor: HUND HELMUT
IPC: B30B9/20
Filed: 1986-10-29
Abstract: An extended nip press comprising a fixed yoke 5, press shoe 7, flexible tubular casing 6, and non-rotating guide assembly 10 about which the casing is rotated in use is characterised in that the guide assembly is constructed such that it may be expanded or contracted to allow for changes in length of the circumference of the casing during use. The latter may be effected by means of an elastic tube 22 connected to a source of pressure, or by a spring. The guide assembly may be polygonal in cross-section or its outer surface may be provided with longitudinally-extending ribs and grooves, which may be straight or helical. The ribs may be radially elastic. Both casing and guide assembly may be moved towards and away from press roll 2 independently of the press shoe e.g. by a hydraulic actuator. The sides of the guide assembly may be arranged to be slidable transverse to its axis. <IMAGE>
Patent GB-2184915-A (GB)
Title: Imaging apparatus
Inventor: SMITH JAMES MUIR
IPC: H04N5/353
Filed: 1987-01-27
Abstract: The sensitivity of the image sensor is controlled differently respectively during a first and a second plurality of interlaced raster scans. The sensitivities may be respectively high and low so that, in effect, a greater dynamic intensity range of the sensor is obtained. The video signal portions associated with the respective periods may be displayed on two different monitors or in different portions of the screen of a single monitor. For missile guidance the higher sensitivity signals display a relatively dull target while lower sensitivity signals show only the missile flare to avoid confusion by cloud edges and the like. A C.C.D. sensor 3 provides rapidly changeable sensitivities, the charges from the "integration region" which senses the input radiation being clocked into the "store" by means of a pulse generator 7. This generator controls the timing of reverse and forward transfer of charges in such a way as to achieve control of sensitivity. Odd and even control layers 15, 16 provide higher sensitivity for odd lines than for even lines of the scan. <IMAGE>

Title: Apparatus for affixing fasteners to a conveyor belt
Inventor: HARGREAVES ARTHUR
IPC: F16G3/00
Filed: 1987-02-28
Abstract: An apparatus for affixing a plurality of fasteners (12) to one end of a portion of a conveyor belt has an affixing head (30) which is movable stepwise across the end of the belt (10). The affixing head (30) has three separate portions, namely a fastener deforming and stapling head (54), a staple folding head (56) and a staple flattening head (58). Upper and lower portions of the affixing means (30) are relatively displaceable by means of a cam (66). As the upper and lower portions are brought together, the fastener deforming and stapling head (54) deforms a fastener (12) and clamps the arms of the fastener onto the belt. Simultaneously, the corresponding lower die portion inserts a staple through aligned holes in the arms of the fastener. After the upper and lower portions of the affixing means (30) have been brought together, the staple folding means turns over the ends of a staple protruding from a fastener. Simultaneously with the operation of the deforming head (54), a staple which has previously undergone the other two operations in previous cycles has the turned over ends of the staple pressed towards the fastener by the flattening head (58). The affixing means (30) is indexed stepwise in steps equal in length to the spacing of the fasteners, whereby each fastener is acted upon sequentially by the fastener deforming head (54), the staple folding head (56) and the staple flattening head (58) as the affixing head (30) is advanced. <IMAGE>

Title: Ammunition feed on an automatic firearm
Inventor: SCHOCH CARLOS
IPC: F41A9/82
Filed: 1987-03-16
Abstract: In an ammunition feed on an automatic firearm cartridge clips 11 filled with cartridges 12 are loaded by hand into a magazine (10). In order to ensure that the ammunition feed functions properly an empty cartridge clip must first be inserted before the full cartridge clips can be loaded. Therefore a catch lever 39 is swivelled about axle 40 by spring 41 to place a stop 42 in the insertion path when the magazine is empty, the stop only being pushed out of the path when a clip has been inserted. Only when the operator is inserting an empty clip will he have a hand free to swivel the lever 39 away. <IMAGE>

Title: Hydraulic power assisted vehicle steering system
Inventor: TAYLOR JOHN CRAWSHAW
IPC: H01H37/00
Filed: 1987-05-07
Abstract: The system has a control valve which controls assistance pressure to a servo motor, the control valve having two valve elements which are rotationally displaceable relative to each other in response to a steering input and from a neutral condition to determine the power assistance which is provided. The two valve elements are biased to the neutral condition by a torque rod or spring. A vehicle speed responsive pump 26, the output from which increases in pressure as vehicle speed increases communicates by way of a non-return valve 30 with a ball clutch that reacts in response to an increase in hydraulic pressure to increase restraint to relative rotation between the valve elements. The non-return valve 30 communicates downstream thereof with an hydraulic accumulator 31, the accumulator 31 communicates with the ball clutch and maintains a source of hydraulic pressure for temporary actuation of the clutch in the event of the pump 26 failing. <IMAGE>
Patent GB-2208739-A (GB)
Title: Liquid crystal devices
Inventor: BOWRY CAROLYN
IPC: G09G3/36
Filed: 1987-08-12
Abstract: In a method of driving a matrix of ferroelectric liquid crystal devices in a TDM mode, a strobing signal comprises a first and a second pulse 24, 25 of mutually opposite polarity and either or both of the data ON and data OFF signals 27, 28 comprises n pulses of alternately opposite polarities (where n>1) spanning the same time period as the first pulse 24 or the second pulse 25, or 2n such pulses spanning both those time periods. By use of the relatively short n or 2n data pulses of alternately opposite polarities, the effect of crosstalk due to the multiplexing is reduced, because the liquid crystal director of an unaddressed device moves only a small distance in one direction, followed by a small distance in the opposite direction, in response to the successive pulses. <IMAGE>
Patent GB-2208741-A (GB)
Title: Liquid crystal devices
Inventor: BOWRY CAROLYN
IPC: G09G3/36
Filed: 1987-08-12
Abstract: In a method of driving a matrix of ferroelectric liquid crystal elements in a TDM mode, first or second data signals are selectively applied to the data lines and the strobing pulses applied to each strobe line occur in contiguous time slots (35-37, 29) instead of occurring in spaced-apart time slots as in the conventional systems whereby at the end of a strobing signal there is no residual dc level remaining across any addressed element. The applied signal may comprise pulses of opposite polarities in alternate time slots, or a pulse of one polarity occupying first and second time slots and a pulse of the opposite polarity oocupying third and fourth time slots. Alternatively, the signal may comprise pulses of the same polarity in first and fourth time slots and a pulse of the opposite polarity occupying the second and third time slots. Where two adjacent time slots are occupied by a single pulse, that pulse may be stepped so that the second half of the pulse has a different amplitude from the first lay. This allows flexibility in setting the pulse amplitude to take account of the switching characteristics of the liquid crystal elements. <IMAGE>
