Title: Recursive processor employing redundant number arithmetic
Inventor: KNOWLES SIMON CHRISTIAN
IPC: G06F7/544
Filed: 1993-09-22
Abstract: A processor 300 suitable for recursive computations incorporates multiplier cells 316 connected to form rows and columns. Each row is arranged to multiply by a coefficient. It begins with accumulator cells J, and continues with multiplier cells arranged to multiply by individual coefficient digits and disposed in descending order of digit significance. Columns other than the first begin with a multiplier cell, and the higher significance columns terminate at respective accumulator cells J. Any intervening multiplier cells are arranged in ascending order of multiplier digit significance. The cells operate in accordance with signed digit number representation arithmetic involving digit redundancy. They generate sum and transfer digits for output, via delay latches (shown as triangles), down columns and along rows respectively to neighbouring cells, in the direction of increasing digit significance in the case of transfer digits. The cell arithmetic employed makes it possible to compute results most significant digit first. Each result digit is recycled when formed to provide a multiplicand digit input for all multiplier cells of a respective row in accordance with result digit significance. The processor is also arranged to add successive non-recursive input terms unto multiplier products. The processor may provide a first order infinite impulse response (IIR) filter section (Fig 5), and two cascaded processors provide a second order IIR filter section (Fig 6). <IMAGE>

Title: Fluid boiling-point measuring device
Inventor: BUCHANAN NIGEL ALEXANDER
IPC: G01N33/28
Filed: 1994-03-01
Abstract: A portable fluid boiling point measuring device (1) includes a probe (2) for immersion in the fluid to be tested. The probe (2) comprises a casing (2a) and plug (9) defining chambers (3, 4) semi-encapsulating a sample of fluid (3a). The fluid (3a) is kept at an optimum level by a quantity of air being trapped in the upper chamber (4) above apertures (6a). The plug (9) separates chambers (3, 4) with a central fluid connection (9b 9c, 9d). A heater (8) around a central conduit (9a) heats the fluid (3a) causing fluid circulation upwards, cooler fluid being drawn down the conduit (9a) over a temperature measuring device (10). The test fluid (3a) ceases to circulate at boiling point when its temperature equalises. The device (1) shows this equalised temperature on the display (11). Fluid above boiling point vents through apertures (9c, 9d, 6a) and cooler fluid enters from base aperture (5) stabilising the boiling point. <IMAGE>

Title: Improvements in and relating to packaged beverages and packaging therefor
Inventor: REYNOLDS ANDREW JOHN
IPC: B65D79/00
Filed: 1993-12-23
Abstract: Devices are described for fitting into pressurised individually packaged beverages (typically canned beers, ales and stouts), by which gas at high pressure is stored within the package for jetting into the beverage as the package is opened to atmosphere. One embodiment comprises a length of tube (10) having a gas jetting orifice (14) which in use is submerged below the beverage in a pressurised can having a gaseous headspace, which can be used to charge the tube with gas during the passage of the filled can (16) along a conventional canning line, on which the can is inverted after filling which brings the orifice into the gaseous headspace. A more preferred design of device comprises a moulded plastics capsule (34; 50; 78) secured near the bottom of a can (20, 88) with an internal, preferably central, pipe (56; 62; 80) to provide a liquid seal to prevent loss of gas when the can is inverted from the upright position, and an airlock when the can is upright to prevent beverage which has entered the capsule from leaving it when the can is opened to atmosphere. A further design of capsule (96) having a central internal pipe (98) and adapted to be pressurised solely by the ingress of beverage, which is fitted midway down a can (94) but which still only jets gas on opening, is also described. <IMAGE>

Title: An engine mount assembly having a modular damping unit
Inventor: TOURNIER PASCAL
IPC: F16F13/24
Filed: 1996-09-24
Abstract: An engine mount assembly comprises a rigid cover 5 secured to a vehicle body or chassis. The cover 5 supports rubber elements 6B, 8B having rigid metal jaws 10, 12 into which is inserted, as a unit, damping module 20. The damping module 20 comprises two identical moulded valve elements 26, 28 having a moulded valve arrangement (40, fig 2) therein and being supported by bellows 22, 24, eg of thermoplastics. A bolt 56 secured to the engine passes through valve elements 26, 28, thereby holding damping module 20 in position. The bolt 56 also transmits engine vibrations to the damping module. Relatively low frequencies of engine vibration are damped by helical conduit 64 which provides a restrictive path for hydraulic fluid to move from one bellows 22, 24 to the other. At higher frequencies, valve flaps (48, 50, fig 2) vibrate causing alternate small compression and expansion of the bellows 22, 24 and thus reducing transmission of the vibrations. In another embodiment (see fig 3)bellows 22 does not contact the cover 5 and thus it acts solely as a compensating chamber.

Title: Trailer towbar assembly with steering control mechanism
Inventor: RODBARD JEFFERY WILLIAM
IPC: B62D13/04
Filed: 1996-12-17
Abstract: A towbar assembly U allows the towing vehicle V to vary in pitch attitude to the towbar assembly U, whilst turning angles made between the two will steer the road wheels A of the assembly to the required positions up to a 90 degree trailer X to towing vehicle V angle, as shown in Fig.2. The towbar assembly U complete with road wheels A, can be attached via front springs or otherwise, to the forward end of the body or chassis of a trailer X having separate rear wheels, to produce a stable and easily reversible trailer. A rotable member M positioned at the pivot L between the towing vehicle and trailer, drives a chain N which is conected to the track rods E of the steered wheels A via links P, Q and plate G, whilst a cam plate T maintains tension in the mechanical links P, Q and chain N. The mechanical relationship between towing vehicle turning angle and the steered wheels is tailored for different sizes of trailer by selection of a suitable cam plate T installed in the assembly. Provision can be made for allowance of small misalignments of the two vehicles, the effect on the steering being illustrated in Fig.3.

Title: Rocking infant holder
Inventor: AFZAL SHER
IPC: A47D9/02
Filed: 1997-04-23
Abstract: An infant seat or cradle has a motor 12 causing reciprocal motion thereof on wheels 20 which are guided in a track 22. Partial actuation of the motor causes the wheels to engage only in a straight central portion of the track whilst full actuation causes the wheels also to engage upturned end portions. Change between the two motions may be controlled by computer 11 in response to signals from a close proximity sound scanner and a movement sensor. If motion or crying is detected then after a predetermined delay motion will be started to settle the infant. After a further predetermined time, a chime or music controlled by the computer may also sound. The motor may have a gear 115 driving a rack (117, Fig 2) and springs (23, Fig 2) may bias the wheels to a central position. The device may be externally powered or have internal batteries 14 and/or solar cells.

Title: Adaptive feedforward control system and method for reducing vibrations generated by pistons
Inventor: CHAMPION SHAUN L
IPC: F16F15/02
Filed: 1997-09-29
Abstract: An adaptive feedforward vibration control system reduces vibrations at fundamental and harmonic frequencies of matched reciprocating pistons, such as the back-to-back compressor pistons 2, 4 in a Stirling cycle cryocooler 14. The pistons are driven by motor drives 32, 34 connected to servos 28, 30 and signal generators 24, 26. A vibration sensor 22 senses vibrations caused by the pistons. A processor 20 converts the sensed signals from the time domain to the frequency domain, preferably by Fourier analysis, and calculates the fundamental and harmonic frequencies of the vibrations. At least one of the pistons 2, 4 is then driven with correction signals from the processor 20. The correction signals are computed iteratively to increase their accuracy and need only to be updated relatively infrequently to adjust the pistons' motions, thereby enabling the use of a relatively slow microprocessor. The system is also applicable to reducing the vibrations generated by a pair of opposite expander and balancer pistons 8, 10 in a cryocooler.
