Patent GB-2082694-A (GB)
Title: Sealing inlets and/or outlets of process vessels
IPC: D01F9/32
Filed: 1981-07-31
Abstract: In apparatus for heating a woven sheet 10 of conducting non- combustible material in order to fully or partially carbonise the material, the sheet 10 is passed by conveying rollers 30 through a pressure vessel 16 having an inert atmosphere of nitrogen gas, and is heated by passing a current through the material by means of the conveying rollers 30 connected to a unidirectional voltage source. At the inlet and outlet of the pressure vessel the sheet is fed through a trough 20 containing spherical ferrite particles 22 of about 75 microns in diameter. An electromagnet 24 connected to the base of the trough 20 produces a magnetic field which causes the particles 22 to be held into sealing engagement with the sheet 10 of material passing through the trough, to prevent escape of nitrogen from the pressure vessel and egress of air into the vessel. <IMAGE>

Title: Electro-hydraulic robot positioning system
IPC: B25J9/16
Filed: 1981-12-22
Abstract: An electro-hydraulic control includes a closed loop hydraulic system comprising a reciprocating pump (55) which forces hydraulic liquid under pressure into the system and hydraulic actuators e.g. 60, 62 which are operated by hydraulic pressure in the system to perform some kind of useful work. A valveing arrangement (58) in the system directs hydraulic liquid from the pump always to the delivery side of the system and also directs the movement of the hydraulic actuators in accordance with the particular work operation to be performed. An electric servomotor 10 controlled by eg a computer (Fig. 1, not shown) rotates a thread 14 to move a carriage 37 connected to a reciprocating piston 48 in a final cylinder 50 of the pump 55. An accumulator 82 controls minimum pressure in the system. <IMAGE>

Title: Television display system
Inventor: DREWERY JOHN OLIVER
IPC: H04N7/01
Filed: 1982-01-25
Abstract: A subjectively higher-definition television receiver display based on GB 2050109A receives a conventional TV signal (e.g. 625/50 2:1 interlaced PAL), and by use of storage devices and special scan control circuitry displays with a scan in which (a) the field rate is double the input field rate (b) the number of lines per field is the same as the input (c) there is a 4:1 interlace and (d) the vertical line displacement between adjacent output fields alternates between one and two output picture lines. The output line content is formed such that (a) each line of an even-numbered or odd-numbered output field is derived from lines of an even or odd input field respectively, and (b) each output line is formed from input lines which are vertically closest to it when the output line structure is notionally superposed on the input line structure with each output line being vertically displaced by one-quarter of the input picture line spacing from the input lines (Figure 6 not shown). In an alternative mode of operation (Figure 7 not shown) the output lines are formed from one or a combination of lines in the nearest input field, and the output line formation can adaptively switch between the two modes in dependence upon scene content, e.g. motion. <IMAGE>

Title: Ultrasonic flaw detector signal analyser
Inventor: CRECRAFT DAVID IAN
IPC: G01N29/38
Filed: 1982-02-05
Abstract: A signal analyser for analysing the echo signals generated by an ultrasonic flaw detector, particularly in the region of geometry echoes comprises a number of signal processing channels (10), each arranged to receive a portion of the echo signal via a time gate (34) which is operated by a clock (14) or a clock (58) emitting gate pulses, and a shift register (12). Each signal processing channel (10) includes hold circuit (40) or (74) which holds the peak value of the signal in the respective time gate, an averaging filter (42) or (76) the output from which represents the average "grass" level, a first comparator (44) or (78) the output from which represents the difference between the outputs from the hold circuit and the averaging filter, and a second comparator (46) or (80) which receives the output of the first comparator and a threshold signal. The second comparator only has an output if the output of the first comparator is greater than the threshold signal, and thus represents a flaw and this output enables a tri-state buffer to pass the output of the first comparator to the output data bus. <IMAGE>

Title: A pump
Inventor: KNOWLES ALBERT HENRY
IPC: F03B13/26
Filed: 1982-02-18
Abstract: A pump having a chamber (1) provided with a movable partition (5) in sealing engagement with the chamber walls, but which has a valve (10) which allows the passage of liquid to be pumped entering the chamber at one end as the partition moves through the chamber towards that end. At a predetermined position of the partition (5) in the chamber and prior to a lifting action the valve (10) is closed thus trapping an amount of liquid at one side of the partition. At this point pressurised air is introduced through the pipe 6 to the other side of the partition (5) to initiate a pumping action to move out the partition in the other direction and lift the trapped liquid out of the pump. <IMAGE>

Title: Sanitary fittings
Inventor: HUNZIKER WERNER
IPC: E03C1/086
Filed: 1982-06-09
Abstract: The external outlet pipe conveying cold water 11 is a hydraulically deformed thin-walled pipe having a cross-section narrowing from the inlet towards the outlet The outlet extremity 11a of this outlet pipe 11 is angled over and terminates in a holding ring 14 having an internal screw thread. The hot water passage is a flexible tube 9 traversing the external outlet pipe 11. At the inlet side, the tube 9 is fastened to a guiding pipe section 7 installed in the housing 1 of the fitting, co-axially to the corresponding terminal part of the external outlet pipe 11. At the outlet side, the tube 9 is fastened on a connector of a coupling pipe element 13 the other connector of which, centred co-axially in the angled-over terminal section 11a of the external outlet pipe, is joined hermetically under thrust to the internal sleeve 15c of a jet divider insert 15. The external sleeve 15a of the insert 15 is screwed into the holding ring by means of an external screw thread, so that the whole jet divider insert may be unscrewed manually. The opening portion of the internal sleeve 15c is conically chamfered at the outside, at an acute angle; a negative pressure area causing rapid mixing of the two separately supplied water flows is thereby engendered in the cold water outlet. <IMAGE>

Title: Apparatus for propelling abrasive medium
Inventor: EDGAR PAUL
IPC: B24C5/02
Filed: 1982-07-20
Abstract: An apparatus for propelling an abrasive medium comprises a hand- held container (10) refining a cavity 10a for a self-contained supply of propellant medium and an inner container (16) defining a cavity (16a) for a self contained supply of abrasive medium. The cavity (10a) connects with an abrasion resistant nozzle (24) with a venturi through a control valve (28), and the cavity (16a) also connects with the nozzle (24) through a tube 22. Pressure on a cap (30) opens the valve (28) and passage of the propellant causes abrasive to be drawn to the nozzle (24). No abrasive therefore contacts the valve (28). <IMAGE>

Title: Centrifuge and method of operating same
Inventor: CALVERT COLIN
IPC: B04B11/04
Filed: 1983-02-07
Abstract: A centrifuge comprises a rotor (16) which tapers conically downwardly from a maximum diameter upper region (16a) to a central bottom opening (26) through which a liquid entry pipe (28) projects upwardly. An outlet end of the entry pipe is shrouded by a concentric cone (30) which is mounted for rotation with the rotor. A flexible diaphragm (32) is secured to the outlet end of the pipe and extends towards the cone so that liquid entering the rotor is directed to flow over an inwardly facing surface of the cone. By this means, the spin of the rotor is transmitted immediately to the liquid. During operation of the centrifuge, rapid changes in the rate of rotation of the rotor are effected so that solids which have separated from liquids in the rotor and have accumulated in the upper region (16a) are dislodged therefrom. <IMAGE>
