Patent GB-2122128-A (GB)
Title: Valve control mechanism
Inventor: GILBERT JOHN DEREK
IPC: B29C45/00
Filed: 1982-06-24
Abstract: A valve control mechanism comprises an enlarged diameter portion (7) in a sealed fluid-carrying duct (8). The portion (7) contains a magnetised (10) valve member (9) carrying an external screw-thread (17) which co-operates with a screw- thread (13) formed internally of the portion (7). The valve member (9) has a valve surface (14) at one end which co-operates with a valve seat (15) at one end of the portion (7), a discontinuity (16) or other passage being formed in the valve member (9) to prevent it from otherwise impeding fluid flow. A ring-shaped magnetic adjustment member formed from two interconnected identical half-rings (1, 2) is made of a synthetic plastics material, such as nylon, by conventional injection moulding and contains a particulate magnetic filler, such as ferrite powder, magnetised to produce radially inwardly directed N and S poles. When the member (1, 2) is rotated around the portion (7), the magnetised valve member (9) revolves and is moved axially by co- operation of the screw-threads (13, 17). <IMAGE>

Title: Aperture mask for image scanning and recording apparatus
Inventor: MITSUKA IKUO
IPC: H04N1/036
Filed: 1982-07-23
Abstract: An aperture mask 22 for use in the recording section of an image scanning and recording system is disclosed. The aperture mask defines a pair of apertures 29 of preferably identical size and shape in alignment with the optical path of a light beam 24 for exposing a recording material. Due to dispersion of the twin light beams after passing through the apertures, and to exposure spread in the recording material, scanning the twin light beams in a direction 26 at right angles to their direction of separation produces an exposed strip 27' having substantially straight ends (as against the round ends produced by a single scanning beam). <IMAGE>

Title: Security device for a closure
Inventor: MANDER MICHAEL GEORGE
IPC: E05C9/18
Filed: 1983-07-22
Abstract: A security device has a primary latch bolt (11) movable between extended and retracted positioning by operation of a handle (14) between a rest position (14a) and a first operative position (14b). Secondary latch bolts (20) are also movable between extended and retracted positions by operation of the handle (14) between said rest position (14a) and first operative position (14b). The handle is also movable into a second operative position (14c) to move the secondary latch bolts (20) into a further condition in which they are extended beyond said second condition. In this, further extended, position the chamfers (35) on bolts (20) engage rounded surfaces on the keepers (36) to force the closure (17) tightly shut. As shown the primary latch (11) and a dead-bolt (12) may be operated by a conventional device (13) with a handle adapted to move bolts (20) by the pin-and-slot, lost motion connections involving levers 27. <IMAGE>
Patent GB-2130374-A (GB)
Title: Process and device for locating and monitoring the position of transport vehicles
Inventor: GAGNEUX BERNARD MICHEL ROLAND
IPC: G01C21/26
Filed: 1983-07-22
Abstract: This process permits a vehicle to locate its position on a given route and to identify service stops on a municipal transport system, i.e. underground train, omnibus train, tramway, etc for the purposes of an automatic announcement of stations to travellers. The distance covered by a vehicle between two consecutive stops is measured, and measurements thus made are analysed automatically by comparing them with known distances between consecutive stations on a route which are stored in the form of a table. The comparison permits the station at which a vehicle is located to be calculated. At the beginning of a route (or if the position is "lost") the measurement and comparison is repeated until the position is located. The process may be complemented by detecting other identifiable features of the route which occur between stops such as changes in direction. <IMAGE>

Title: A pump for dispensing metered amounts of fluids
Inventor: RAPP KARL GUNTHER
IPC: B05B11/00
Filed: 1984-03-16
Abstract: An economical pump for dispensing metered amounts of fluid which is easy to assemble is proposed, wherein a piston 3 - in the form of a push-button - is displaceable against a spring 4 in a housing 2 which is mountable on a ventilatable container. A metering chamber 7 is formed between the piston and a dividing wall 22 in the housing, which wall is horizontal i.e. perpendicular relative to the axis, and a reduced pressure is created in said metering chamber by piston movement. A riser tube 1 - capable of being shut-off by a first non-return valve 53 - extends, in use, from the container end into said metering chamber which is connected to an outlet in the piston via a second non-return valve 61. In such case, one-piece flap valves are proposed with a self-springing valve flap provided both in the piston and at the inlet of the riser tube leading into the metering chamber. <IMAGE>

Title: A reactor for quench catalytic cracking of crude oil and residua
Inventor: WALLS JOHN RAYMOND
IPC: C10G15/08
Filed: 1984-04-03

In this new technique only the catalyst itself achieves high temperatures. Thus carbon formation by pyrolysis in the fluid phase is avoided.
Patent GB-2139117-A (GB)
Title: Marking tape for animal husbandry
Inventor: LUMBER PERCIVAL MICHAEL PAUL
IPC: A01K11/00
Filed: 1984-04-18
Abstract: A marking tape has a carrier formed by a layer 1 of plastics material and a fabric layer 2. An adhesive layer 3 permits the tape to be attached to an animal, after removal of a protective layer 4 which protects the adhesive prior to use. A facing layer 5 of a different colour from the plastics layer 1 is secured to the plastics layer 1 so that it is removed by frictional contact. Thus, if the tape is stuck onto the buttocks of an animal, frictional contact of an animal during service or bulling causes the facing layer to be removed, providing a clear indication to the herdsman of the condition of the animal. <IMAGE>

Title: Improvements in or relating to leak detectors
Inventor: COX ANDREW PETER DAVID
IPC: G01M3/00
Filed: 1984-04-26

Patent GB-2146304-A (GB)
Title: Container for pressurised liquid
Inventor: RILEY ARTHUR JOHN
IPC: B65D77/06
Filed: 1984-06-22
Abstract: A flexible bag 10 adapted for reception of a pressurised liquid, e.g. a carbonated beverage, sparkling wine or beer, and having a tap 15 whereby the liquid may be dispensed is enclosed within a cylindrical, plastics or paperboard casing 11 at each end of which is a respective end cap 12, 13. To minimise head space in the bag 10 as the liquid is dispensed so that the liquid does not go flat or stale, one end cap 13 is movable inwardly of the casing 11. This may be achieved simply by pushing downwards on the end cap 13. The movable end cap is preferably part spherical in form and has an auxiliary resilient plate 20, the plate being screw threadedly connected to a handle 30 via an aperture in the end cap. Tightening of the screw threaded connection causes plate 20 to press against convex lower face of the cap so flattening it and expanding its rim into tight engagement with the casing. In this tight fitting position the cap cannot be pushed further into the casing but the entire container can be moved around. To prevent accidental removal of cap 13, e.g. when temperature is high, protrusions may be provided on the inner surface of the casing. Alternatively the cap and casing may have co-operating screw threads (Fig. 4) or ratchet formations to hold the cap in a desired position.   <IMAGE>
