Title: Preventing misuse of cards in card freed apparatus
Inventor: WYATT STANLEY
IPC: G07F7/00
Filed: 1990-02-13
Abstract: Apparatus freed by a coded card includes at least two sensors 12 or 30 and 26, eg optical sensors, spaced apart in the direction of movement A of the card such that a credit is only signalled to a microcomputer controlling use of the apparatus eg for game playing, if when the card has cleared sensor 26 the sensor 12 or 30 has also been cleared. If sensor 12 or 30 has not been cleared the inference is that the card is being withdrawn, eg by a string attached to the card, and an alarm is signalled. Both sensors 12 and 30 are preferably provided, sensor 30 indicating the presence of a tag 32 on a pivotal gate 16 when the gate is in a closed position, ie that the rear of the card has passed the gate which has then returned by bias to the closed position. The card is driven by pinch rollers (44, 46 Figure 2) past the second sensor 26, the rollers reversing if a card is not acceptable. Stops prevent the plate going past its closed, upright position. A battery powered supply may be provided such that the sensors and means for signalling an alarm condition remain operational with the apparatus switched off or during a power failure. <IMAGE>
Patent GB-2234606-A (GB)
Title: Car assembly line control
Inventor: NOMARU MINORU
IPC: B23P21/00
Filed: 1990-04-26
Abstract: An automotive vehicle body assembling line includes a floor assembling unit a body side assembling unit and a vehicle body assembling unit for positioning the body side and the floor and joining them. During final assembly, the pushing forces applied to points on the body side are measured. The measured forces are compared with predetermined forces required to push the points of the body side when each of the floor main components is misplaced a predetermined amount from its correct position to determine if any floor component has been positioned incorrectly by the floor assembling unit. Position errors are estimated from the pushing forces using standard equations which are then used to control the floor assembling unit to eliminate the estimated position errors in subsequent vehicles. Positions may also be measured directly to obtain the standard equations. <IMAGE>

Title: Demountable extensions for motor vehicle clutch, brake and accelerator pedals
Inventor: BAKER JOHN EDGAR THOMAS
IPC: G05G1/487
Filed: 1990-10-09
Abstract: The pedal extensions attach directly to the existing brake and clutch pedals by one nut on each only. The accelerator extension consists of a pedal (22) fixed to the existing floor, or a raised floor (20) behind the accelerator, by means of a base plate (23) on which the pedal pivots backwards and forwards. A coupling rod (24) connects the top of this pedal to a clamp (25) which is secured to the accelerator pedal (26) by a single bolt. When fitted, the pedal extensions give up to an extra 7.5 cm. reach, thereby improving the driving position for small people.

Title: Image data compression with dynamically controlled quantiser
Inventor: STONE JONATHAN JAMES
IPC: H04N7/26
Filed: 1991-09-19
Abstract: A dynamically variable degree of quantisation Qs is applied to decorrelated 12 input image data to control blocks of data output from the encoder to have a predetermined maximum size. The number of compressed bits stored in field store 60 is counted 62 and the count used to address a look up table 64 storing the quantisation factors Qs which are applied to quantiser 14. If counter 62 indicates that too many bits have been passed to store 60 then an overflow indicator may be inserted 67 in the compressed image data signal. The technique of variable quantisation may be applied to sub-band filtered image signal which is then resequenced to transmit those coefficients containing most significant information first. <IMAGE>

Filed: 1992-03-02
Abstract: Apparatus and method for transferring segmented memory units (756, 764) determines a need for memory transfer and searches a memory unit segment by segment until a valid data record is found. This valid data record is conveyed to another memory unit via the asynchronous mode. If a valid data record is not found within a predetermined amount of time, a message identifying the memory segment last searched is conveyed. If no remaining valid data records are found, a message with no information is conveyed. Priority is given to asynchronous messages. <IMAGE>

Patent GB-2259765-A (GB)
Title: Optical sensing
Inventor: PEACOCK STANLEY JOHN
IPC: G01N21/55
Filed: 1992-09-18
Abstract: An optical sensor 10 senses the presence of an analyte in a fluid. The sensor has a surface plasmon resonance-sensitive device 17 which reflects light from a light source 11 to a light detector 34. A 'pinhole' aperture 33 determines the portion of the reflected light which is permitted to reach the light detector. On exposure to the analyte, via inlet pipe 24 and outlet pipe 25, the device 17 responds so as to alter the intensity of the light reflected to the light detector 34. The detector produces an output signal representative, for example, of the concentration of the analyte. The concentration is indicated by an indicating means 35. The 'pinhole' aperture 33 may be replaced by an optical fibre end 37 (fig. 3, not shown). <IMAGE>

Title: Preparation which inhibits the autoimmune response in HIV, or SLE, patients
Inventor: HOLMS RUPERT DONALD
IPC: A61K38/00
Filed: 1994-06-08
Abstract: It is an object of the present invention to provide preparations for the treatment or prophylaxis of AIDS and systemic lupus erythematosus and related disorders. The invention is based on the discovery of the process triggered in the immune system by HIV which leads to AIDS. HIV has a specific mechanism to activate the immune system to allow it to replicate and this same immune activation leads to an autoimmune process which eventually leads to AIDS. The preparation for treatment comprises novel synthesized peptides whose amino acid sequences are derived from a human protein called ezrin and are based on the following sequence: NH2ThrGluLysLysArgArgGluThrValGluArgGluLysGluCOOH SEQ ID. No. 2. The mechanism of action of these peptides is that they switch off specific retrovirally induced immune responses by immunological tolerance.
