Title: Improvements to road rollers
Inventor: TAYLOR HAROLD
IPC: E01C19/25
Filed: 1981-10-21
Abstract: The present invention is of a road roller consisting of a strong chassis (a) carrying a large steel tank (b) which is divided into compartments (c) with connecting valves (h) so that the water ballast in the container can be moved from side to side to vary the loading on the roller (d). Jockey wheels (e) and tow bars (f) are attached for towing by tugs. Water ballast can be added to the tank to increase the rolling load or water ballast may be abstracted from the tank to decrease that load. The size of the tank or container is such that the load on the roller far exceeds that of the conventional road roller and yet by emptying out the water ballast the roller can safely traverse present bridges. <IMAGE>

Title: Electronic image processing
IPC: G06V10/28
Filed: 1981-04-16
Abstract: An electronic image processing system, for image enhancement and noise suppression, from signals representing an array of picture elements, or pels. The system is of the kind providing a feature-enhanced output by the addition of outputs of a high-pass filter acting as image-feature detector and a complementary low-pass filter. The low-pass filter also acts as an image-feature detector and includes a prefilter (130 and Figure 22) and a sub-sampling filter (32) based on a set of weighting patterns in the form of sparse matrices (Figure 23). The sub-sampling filter in a bandpass channel of the low-pass filter (206 and Figure 28) comprises a pair of gradient detectors (210, 220, 230, 240 and Figures 32, 33, 34, 35) arranged back to back.
Patent GB-2096283-A (GB)
Title: Electro-fluid control device
IPC: F16K31/06
Filed: 1982-03-23
Abstract: An electrically-operable fluid pressure control device (10) in which the valve elements are magnetically susceptible discs (51, 52) operable by pot-coil electromagnets (63, 64) to close or not close at separate or simultaneous times respective ports (41, 44). When not closing these ports the discs can close other ports (42, 43) but not both at one time by the opposition of a link member (7) which is also effective to aid the unseating of one disc from the respective port of 42 and 43 when the other disc approaches. The speed and reliability of operation are obtained from this construction by relatively simple and non-critical manufacture. The fluid can be gas or liquid as no close-tolerance sliding surfaces exist. <IMAGE>

Title: Simulating a field of view from a stored background image
Inventor: HOHMANN THOMAS
IPC: G09G5/34
Filed: 1982-08-27
Abstract: For the simulation of the visual field of view in the training of a battle situation, a TV monitor is arranged in the field of view of the optics of a person to be trained. On said monitor a cutout (16) of a digitally stored background image (13) is displayed. The cutout to be displayed experiences a continuous change at an aiming motion. In particular when displaying different cutouts on a plurality of monitors, access problems arise due to the memory cycle time of the digital background memory if it is intended to transfer the whole cutout during one TV frame period. In order to prevent those problems, the image cutout is loaded into a buffer memory and with a changed addressing the information in the buffer memory overlapping with respect to the old and new cutout is maintained. Only the new digital image information to be added is loaded from the background memory into the buffer memory at the place where the old image information has to be cancelled. Proper cyclical addressing takes care that the new buffer memory contents are displayed in the correct logical sequence. <IMAGE>

Patent GB-2138186-A (GB)
Title: Pulse train divider arrangement
Inventor: BRENNAND PETER ROBERT
IPC: H03K27/00
Filed: 1983-04-08
Abstract: An input (1) of a pulse train divider arrangement receives a clock pulse train of frequency f and 1:1 mark-space ratio, which input is applied to a first input of an exclusive-OR gate (2). The output of the gate (2) is applied through a delay circuit (3) providing a finite delay period of less than the period of the clock pulse train to the input of a monostable (4) whose pulse output is applied to the input of a divide by two circuit (6) whose frequency divided output is applied to the second input of the gate (2). The arrangement is capable of providing two frequency divided outputs, that at a first output terminal (5) connected to the output of monostable (4) being a first pulse train of frequency 2f/3 whilst that at a second output terminal (7) connected to the output of the divider circuit (6) being a second pulse train of frequency f/3 when the period of the pulses produced by the monostable (4) is greater than half the period of the clock pulse train but less than one and a half times the period of the clock pulse train. The second pulse train always has a 1:1 mark-space ratio when the monostable period is three-quarters the period of the clock pulse train. In a modification the delay circuit (3) may be omitted and the required finite delay provided by the response time of the monostable (4) and/or the divider circuit (6). <IMAGE>

Title: Variable rate speech synthesizer
Inventor: MOZER FORREST SHRAGO
IPC: G10L13/10
Filed: 1983-05-16
Abstract: In a speech synthesizer, a method and apparatus for varying the intonation of a word or a phrase relies on the generation of pitch frequencies independent of the formant frequencies of synthesized speech. Pitch frequency is controlled and varied in successive repetitions of a phrase by reference to an external timing reference, such as stored tables of pitch frequencies as functions of time. At each repetition of a phrase, a different repetition rate produces successive repetitions of the same phrase with desired variations in intonation. The invention finds application in both time domain speech synthesis and frequency domain speech synthesis.

Title: A hydraulic shock absorber with rebound stop
Inventor: BAKER GERARD EDWARD WALSH
IPC: F16F9/49
Filed: 1984-10-12
Abstract: A hydraulic shock absorber has a hydraulic rebound stop. A stop plate 34 supported in the cylinder 12 by a spring 32 acts to obstruct the intake apertures to the rebound valve in the piston 16, to reduce hydraulic flow through the piston. The surface of the piston facing the plate 34 has an annular ridge 38, and the spring 32 bears on the plate 34 (on the opposite side to the ridge 38) around an annulus of different radius so that when the spring 32 is compressed, the plate 34 is distorted (see Fig. 3) to increase the obstruction afforded to the rebound valve intake apertures. The intake apertures and the ridge 38 are actually formed in/on a plate 26 attached to the piston.   <IMAGE>

Title: Improvements in dual brake valves
Inventor: MCCANN DENIS JOHN
IPC: B60T15/04
Filed: 1984-11-23
Abstract: To avoid brake pressure oscillations caused by "cab-nod" in a lorry, a dual brake valve assembly including two co-axial primary and secondary valves (11, 12) for primary and secondary braking circuits is modified to include an auxiliary exhaust valve (50) operable in conjunction with the driver actuated pressure plate (37) and a secondary piston (10) which controls operation of the secondary valve (12) in response to operation of the primary valve (11). When the valve assembly is operated to apply the brakes, the value element (51) engages the annular seat (25) of the piston (10) so the auxiliary exhaust valve (50) remains closed to prevent the premature release of fluid from the primary circuit irrespective of uncontrolled relative movement between parts of the valve assembly. The element (51) may have grooves or radial bores (Fig. 3) to permit a restricted flow to exhaust when it is seated. <IMAGE>

Title: A masking plate for pipes
Inventor: MOLYNEUX GEORGE
IPC: F16L5/00
Filed: 1984-12-19
Abstract: The invention provides a building construction in which there is a pipe passing through a wall with a clearance all round the pipe, to allow for differential settlement of the pipework and the wall, and a masking plate surrounding the pipe and preventing rodents passing through the space between the wall and the pipe. The masking plate comprises at least two sections each of which subtends only part of the perimeter of the pipe, the masking plate fitting in engagement with or closely adjacent to one face of the wall and substantially closing one side of the clearance left between the opening in the wall and the perimeter of the pipe. Because the masking plate is constructed in two sections, it is possible to fit it around the pipe after the pipework is finished. The plate sections may be held together by wire wrapped around lugs 52,54 or by inter-engaging saw-tooth configurations (Figs 6,7 not shown). <IMAGE>
