Title: Rotary contactor
IPC: B01D11/02
Filed: 1980-11-25
Abstract: A continuous liquid/liquid or liquid/solids contactor comprises an outer shell 12 with a rotor therein having axially spaced partition discs 16 dividing the shell into compartments, at least some of which compartments have receptacles 17 carried by the rotor. Passages for phase flow between compartments are provided in or about the discs. At least one end settlement chamber free of receptacles is provided, having means therein, suitably in the form of a weir or funnel, for reducing vortex flow and/or turbulent flow in the settlement chamber.

Title: Electronic Control Arrangement for Fuel Injection Pump
IPC: F02B3/06
Filed: 1981-02-25
Abstract: The arrangement includes a regulating element (7) which is the control rod of a fuel-injection pump (2), the element (7) being controlled by a vacuum servo-unit (11) including a diaphragm (8) to which the element (7) is connected. The servo-unit (11) is subject to a control means (12) which is regulated by a controller (13) which is preferably a micro-processor. Pneumatically operated means (28, 29, 30) is provided for the automatic adjustment of the servo-unit to a predetermined position in the event of failure of the controller (13) or loss of vacuum. The controller (13) controls the control means (12) in dependence on monitored operating parameters of the engine and in the event of breakdown, the position of adjustment of the regulating element (7) corresponds to the idling speed of the engine. The automatic adjustment means may consist of a flap (33) controlled by an electro magnet (32) and a Venturi (30) controlling a valve (29) or it may consist of a flap (33) controlled mechanically by a vacuum- operated means (37, 38); in either case the adjustment means is controlled by the vacuum developed between the control means (12) and the servo unit (11). <IMAGE>

Patent GB-2109871-A (GB)
Title: Gas turbine floating seal
Inventor: WILKINSON WILFRED HENRY
IPC: F16J15/34
Filed: 1981-11-14
Abstract: Leakage of gases through the gap 30 between stator 20 and rotor 22, is prevented by the supply of high pressure air to the space radially inwardly of an annular seal 32 which forms a serpentine airflow path with the rotor disc 24. Relative axial movement of disc 24 and seal 32 is nullified by high pressure air being fed onto the disc face from the seal face to create a back pressure which is fed to a signal generating device 43, change in back pressure causing mechanism 44 to move the seal 32 into proper positional relationship with the disc 24. <IMAGE>

Title: Chromatographic method for recovery of ethylene glycol
IPC: B01D15/08
Filed: 1981-12-23
Abstract: Ethylene glycol contained in washings discharged from an ethylene oxide production process by gas phase oxidation of ethylene with oxygen, is recovered by passing the washings along pipe 6 to a chromatographic separation column 1 whose lower part is packed with a cation exchange resin 2 in salt form. Water from pipe 3 is used to elute the column 1, the effluent from the column 1 being divided into at least three fractions of which at least one is an ethylene glycol-rich fraction, the others containing e.g. organic acids or coloured materials. At least one of the other fractions which contains low concentrations of ethylene glycol is recycled via pipe 7. <IMAGE>

Title: Electrical equipment having diagnostics
IPC: G03G15/00
Filed: 1982-03-30
Abstract: In a stand-alone or add-on sorter for a reproduction machine, the sorter (2) has access to its own collection of diagnostic programs under control of a single push button (14) carried on the sorter housing. A lamp (situated behind window (16)) associated with the push button is used to indicate, by its frequency of pulsing, the diagnostic state of the machine, and a manually- operable switch (26) is used to move the sorter between its normal and diagnostic modes. In the latter mode, a given diagnostic routine may be selected by operating push button (14) a predetermined number of times, this code being accepted automatically when a chosen period of time (e.g. 2 secs.) has elapsed since the last actuation of push button (14). <IMAGE>

Title: Data processing systems for motor vehicles
Inventor: BARRETT PETER MARTIN
IPC: G07C5/08
Filed: 1982-03-31
Abstract: A data processing and recording system for a motor vehicle comprising data processing means, providing part of the system fitted to a motor vehicle and connected to sensors 23 to 26 on the vehicle. The data processing means 1 processes sensor signals and records the processed data on a cartridge 2 forming another part of the system. The recorded data on the cartridge is transferred to a data collection means 3. The data processing means requires calibration data, unique to the vehicle in which it is fitted, to process the sensor signals correctly. The calibration data is generated by the data collection means and transferred to the data processing means by the cartridge. Reference data, also unique to the vehicle, is transferred in the same way. <IMAGE>

Title: >A safety system for a conveyor
Inventor: SARGEANT MICHAEL GARY
IPC: B65G43/02
Filed: 1982-08-04
Abstract: A safety system for detecting faulty bearings of rollers supporting an endless belt conveyor includes an infra-red radiation sensor which is positioned to sense changes in temperature of the conveyor belt. In one method the conveyor is stopped for a time to allow localised heating of the conveyor belt in the region of any faulty bearing. The conveyor is then restarted and moved at a known speed and the areas of localised heating sensed by the infra-red sensor. The elapsed time between restarting the conveyor and detecting the localised heating is measured and the position of the faulty bearing identified.
