Title: Hydrodynamic torque converter
Inventor: DEHRMANN UWE
IPC: F16H41/28
Filed: 1996-10-24
Abstract: A hydrodynamic torque converter (1) has vaned wheels in the form of a pump wheel (7) a turbine wheel (9) and a guide wheel (11). A torque is transmitted from the pump wheel (7) to the turbine wheel (9) by means of a pressure fluid which flows along a flow path from the pump wheel (7) to the turbine wheel (9) and is conducted back via the guide wheel (11) to the pump wheel (7). The wheels (7, 9,11) each comprise vanes (8, 10, 12) connected to an outer wall. At least one wheel includes a stabilising ring (19, 21, 23) which connects the vanes (8, 10, 12) at their inner ends and is arranged to minimise flow losses of the fluid in the flow path.

Title: Method and apparatus for synthesizing spatial waveforms in an electronic position encoder
Inventor: ANDERMO NILS INGVAR
IPC: G01B7/00
Filed: 1997-04-16
Abstract: In a method and apparatus using a capacitive displacement encoder to determine the relative position of two members, e.g. a slide 112 and a scale 114, which are relatively movable along a measurement axis 116, one member (the slide) carries an array of electrodes 132 to which voltages are applied to as to give a waveform which varies spatially along the array, and the second member (the scale) carries one or more electrodes 140 capacitively coupled to the array so as to receive a signal therefrom which varies in dependence on the relative position of the two members. The voltages applied to the array electrodes are varied so as effectively to shift the applied waveform along the array in increments which are smaller than the array electrode spacing 136, and the relative position of the two members is determined from the applied shift, e.g. by adjusting the shift to minimise the voltage signal from the electrode(s) 140 on the second member. The shifts of the spatially varying waveform may be made by modulating a basic pulse waveform using a set of coefficients so as to apply several individual waveforms to each array electrode 132 during a position measurement. As a result, the effective position of the composite spatial waveform is a function of the average of the individual spatial waveforms.

Abstract: A method for the dyeing of textile fabrics containing modified cellulose regenerated fibre, capable of being dyed with cationic dyes, and further containing at least one kind of fibre selected from ordinary cellulose regenerated fibre, cotton and wool, comprises dyeing of the textile fabric with a dyeing solution containing cationic dyes alone or containing cationic dyes and other dyes by a one-bath dyeing method to form a sprinkly pattern, dungaree pattern, chambray pattern, check pattern or striped pattern. The modified fibre capable of being dyed with cationic dyes is obtained by incorporating into the spinning solution, before spinning, polystyrene sulphonate or a compound having anionic groups such as an insoluble polymer which is obtained by cross-linking a dihydroxydiphenylsulphone-sulphonate condensate with epoxy compounds having at least two epoxy groups in the molecule. The method may further include sequential treatment of the dyed textile fabric with an aqueous solution of tannic acid and then with an aqueous solution of tartar emetic. The dyed textile fabric may be further treated with a resin reactive to cellulose for cross-linking, eg an N-methylol-based resin.

Title: Temperature indicating means for electronic components
Inventor: WILKIE STUART EDWIN STANTON
IPC: G01K11/12
Filed: 1998-04-17
Abstract: A thermal interface pad for electrically insulating an electronic component whilst allowing heat dissipation includes means to indicate the temperature of the electronic component. The temperature indicating means comprises a thermochromatic material distributed either on or in the surface of the pad or substantially throughout the pad. The thermochromatic material may give a visual indication that the temperature of the electronic component falls within two or more discrete temperature ranges or may provide a continuous visual change over a single temperature range for more accurate temperature determination. The visual change may be permanent or reversible. Such thermal interface pads may be used to monitor the temperature of electronic components, particularly inaccessible electronic components, during operation in electronic assemblies. More particularly they may provide an indication that a maximum desired temperature has been exceeded.

Patent GB-2337904-A (GB)
Title: Frame erasure for digital data transmission
Inventor: TRUELOVE STEPHEN
IPC: H04B14/04
Filed: 1998-05-29
Abstract: A method of improving frame erasure performance for slow frequency hopping channels utilizes two convolutional decoding steps and two PBER thresholds (8), (high and low), in conjunction with the cyclic redundancy check. The breakdown condition in the convolutional decoding process is detected by means of a 'forward backward decoding' algorithm (see Fig.1). The breakdown condition is detected with two passes of the convolutional decoder. When the decoder breaks down an essentially random burst of erroneous decoded bits are produced, and due to the memory effect of the decoder these will be different in each decoding direction. These erroneous random errors may be detected by comparison (7) of the two decoded sets of data. Application is to GSM.

Title: Headlight with high and low beam reflector units
Inventor: SATO MASAKAZU
IPC: F21Y101/00
Filed: 1998-08-27
Abstract: To provide a headlight for vehicle use in which an upper reflector unit 16A and a lower reflector unit 16B are arranged, capable of ensuring a sufficiently large quantity of light of a main beam so that the visibility can be enhanced in the case of driving at night. A low beam reflector unit 16A and a main beam reflector 16B, are integrated with each other, each having a light source bulb. Direct light emitted from the main beam light source bulb (20B fig 2) passes through a space in the front of the boundary section 22 between both reflectors and is incident on the reflector surface 18A of the low beam reflector unit 16A. Therefore, when the main beam light source bulb (20B, fig 2) is turned on, direct light emitted from the main beam light source bulb (20B, fig 2) is reflected on the reflecting surface of the low beam reflector 18A and irradiated to the front. At the same time, direct light emitted from the main beam light source bulb (20B, fig 2) is also reflected on the main beam reflecting surface 18B and irradiated to the front. Due to the foregoing, it is possible to increase a quantity of light of the main beam.

Title: A mechanised fender for marina-based craft
Inventor: MEREDITH RICHARD GARFIELD
IPC: E02B3/26
Filed: 1999-07-01
Abstract: A mechanised fender pushes a craft away from the pontoon against her mooring lines, and normally maintains a gap between the pontoon and the craft's conventional fenders, thereby minimising hull / gel-coat damage. A spring-actuated torque-arm 3, secured to a spring-housing 1, directs its force to the craft via a removable variable length connecting-arm 5, and permanently secured boat attachment 7. Universal-joints at either end of the connecting-arm 5, together with its screwed-rod section, and the high rangeability travel of the torque-arm 3, cater for all movement of the craft relative to the pontoon. A removable foot-lever (9, Fig 10), enables torque-arm 3 to be accurately positioned, whilst engaging a sliding-plug 4, with the guide on the connecting-arm 5. The spring-housing 1, may be releasably connected to the surface of the pontoon, by clamp 2, or mounted below the surface of the pontoon, and permanently bolted to the pontoon structure.
