Abstract: A vehicle suspension system in which a computer controls damping and spring forces to optimize ride and handling characteristics under a wide range of driving conditions. A controllable shock absorber connected between the wheel and frame of the vehicle includes a hydraulic sensor which provides signals to the computer which are representative of the position of the piston within the shock absorber. The computer utilizes these position signals to control compression and rebound hydraulic pressure regulators by continuously computing, utilizing programmed algorithms, compression and rebound damping forces that will yield the desired ride and handling characteristics. An air spring may be connected with the shock absorber for compression and rebound along the same axis. Pressure sensors and air pressure inlet and outlet valves are connected to the computer for adjusting the pressure within the air spring to provide the desired spring rate.

Abstract: An automatic correction system for the servo-circuit of a device with optical scanning of a rotating information support, with a known servo-circuit, for detecting anomalies in the scanning system (1) to whose outputs is connected a gate circuit, providing as necessary a mute control signal at the decoder (2) connected to the scanning system (1) and thus ensuring the mute control of its outputs. According to the invention, anomalies in scanning caused by external faults and/or disc faults, such as scratches, can largely be reduced, in terms of the disturbance caused by this phenomenon, by the fact that a triggering criterion for correction signals can be produced, in the event of anomalies, by sequential address comparison. This is achieved by the fact that a comparator (6) compares any newly read data with the preceding information, which is temporarily stored in a latch circuit (7) and by the fact that a preliminary indication is made available, in the form of a measurement window $g(D) D in order to determine whether the comparison lies outside the measurement window and in order then to emit a correction signal from the comparator (6) to the servo system (3) and by the fact that the scanning system (1) refers back to the last valid scanning point.

Granted: 1989-06-15
Abstract: A method of wrapping articles in a plastic film. Stretch wrapping film (3) supplied from at least one supply roll (2) is folded and connected to form a tube having a passageway sufficiently large to introduce unit into it and transport it therein, without contacting the tube wall, whereafter the tube is stretched in the longitudinal direction to constrict it and cause it to tautly contact the unit being wrapped. The stretched and constricted tube is closed, possibly sealed and separated in front of and behind the unit being wrapped. A wrapping apparatus comprises a folding and guiding unit which brings the film into a tubular form, and elements connecting the film to form a closed tube. A sleeve member (6) cooperates with positive transport means placed alongside its outer circumference. Drawing means positioned downstream of the positive-transport means are movable in the direction of film transport at a higher velocity than that of the positive-transport means. The machine further comprises a clamping mechanism (4), optionally a sealing mechanism, a separating mechanism and transport means. The transport means are interrupted approximately at the level of the downstream end of the sleeve member, with the upstream portion of the transport means extending through the sleeve member down to at least the downstream end thereof.

Title: Improvements relating to the treatment of medium used in photographic processors
Inventor: TOULSON BRIAN THE ASHLEY BUSIN
IPC: G03C5/395
Filed: 1987-03-02
Granted: 1989-12-14
Abstract: The invention provides an electrolyte cell which is used for the electrodeposition of silver from a fixer medium (used as the electrolyte) which has previously been used and has to be re-used for developing photographic films, X-ray plates and the like processes wherein silver is extruded by the treatment process. Whilst the silver electrodeposition is taking place, air is bubbled through the electrolyte to prevent copper sulflate and the additives in the electrolyte from settling out and aggregating which shortens the life of the fixer medium. The electric potential which is applied to the electrodes is such as to give a much smaller electrolysing current i.e. up to 1 amp compared to the more usual electrolysing currents of 10 amp or more.
