Patent GB-2109771-A (GB)
Title: Bags and the manufacture of bags
Inventor: CLAXTON NIGEL ERVINE
IPC: B31B19/90
Filed: 1982-11-16
Abstract: A strip of tamper proof, reclosable bags 44 comprises two plies 19.1, 19.2 of plastics sheet material secured to one another by welding along transverse zones by folds 20, 22 along their edges. Adjacent bags are connected along lines of perforations. The plies are provided with interengageable male/female rib formations 12, 14 adjacent the folds 20, 22, and a line of weakening is formed by perforations 24, 26 in the plies between the fold and the male/female rib formations to form an edge portion which can be removed by tearing along the line of weakening. The plies are slit at 38 to form openings 46 through which the bags can be filled and thereafter sealed. Prior to opening the bag, the edge portion is torn off. The bag can then be opened to provide access to the contents by disengaging the rib formations 12, 14, and reclosed by re- engaging the rib formations. The bags are produced in strip form and remain in strip form until required for use. <IMAGE>

Title: Orthopaedic traction apparatus
Inventor: SINGLETON TERENCE
IPC: A61H1/02
Filed: 1983-02-11
Abstract: Orthopaedic traction apparatus of the kind including a support structure 31 carrying guide means 33 serving to direct an elongate flexible member 34 between a patient and a suspended weight 37, the weight applying tractive force to the patient by way of the member, is improved by the provision of a safety mechanism 40, 41 of dynamic seat belt type operably connected between the support structure and the weight. The mechanism is preferably of a form having a belt arresting element operable in response to tilting of the mechanism from a predetermined orientation.

Title: Improvements in and relating to conveying systems
Inventor: HART BERNARD EATON
IPC: F04F5/12
Filed: 1983-03-07
Abstract: The present invention relates to a conveying system particularly but not exclusively for conveying a slurry comprising particulate material, e.g. sand, and a liquid, e.g. water, to a gun for providing a high pressure abrasive jet. The high pressure jet is created in the gun (3) to which the slurry at low pressure and high pressure water are provided separately in pipes (2, 5). To assist flow of slurry to the gun at spaced intervals along the slurry carrying pipe (2), the high pressure water pipe (5) is connected to it by bleed devices (6, 7, 8, 9) providing high pressure jets of liquid in the slurry pipe in the direction of flow of slurry therealong. <IMAGE>

Title: Tie for existing cavity wall
Inventor: MILLEN RONALD JAMES
IPC: E04G23/02
Filed: 1983-07-07
Abstract: Rod 4 carrying two spaced spreadable gripping devices 13 and 14 is inserted into bores 23 and 24 in inner and outer wall skins 2 and 3. The rod 4 has screw-threaded portions 5 and 6 at its ends and a pair of flats 7 at one end forming a tongue. On portion 6 are mounted abutment 9 and nut 16 with a frusto-conical surface and lugs 21. On nut 16 are mounted gripping members 12 whose inner surfaces form a complementary frusto- conical contact surface and which have outer bore-engaging bosses 20. On portion 5 are mounted an abutment 8 and nut 15 with a frusto-conical surface, and slot 29. On nut 15 also are frusto-conical gripping members 12. Rod 4 is rotated by the tongue. Nut 16 is prevented from rotation by gripping members 12 and bosses 20, so that it moves towards abutment 9 and spreads gripping members 12 against the bore. When the rod is secure, nut 15 is rotated by slot 29 and moves towards abutment 8, spreading gripping members 12 against the bore. <IMAGE>

Title: Isolator system for data loggers
Inventor: MICHAEL PETER COLIN
IPC: H03F3/38
Filed: 1983-07-07
Abstract: An isolation system for low level output sensors 10-13 typically associated with a multi-channel data logger. The respective sensor outputs are applied across capacitors 50-53 and the capacitor voltage is connected periodically to respective transformers 56-59 via time-multiplexed switches 40-46. Rectangular amplitude modulated pulses resulting therefrom at the secondary transformer winding pass via the multiplexed switches 41-47 to the capacitor 61 and thence to buffer 62. The voltage across capacitor 61 represents the sensor voltage from the most recently switched channel now referenced to ground potential and can be used by the data logger after conversion by ADC 21. <IMAGE>

Title: Warm air driers/air purifiers
Inventor: CHURCH ALAN HOWARD
IPC: A47K10/48
Filed: 1983-08-03
Abstract: A warm air hand drier for washrooms has a very fine filter capable of removing particles down to 0.01 microns, so that instead of circulating germs over the user's hands it removes them. It can be used as a room air purifier, for which purpose the usual timed switch can be over-ridden by a switch that allows the fan to run for a long period without the heater.
Patent GB-2126762-A (GB)
Title: Computerised design
Inventor: JORDAN DAVID
IPC: G06F9/44
Filed: 1983-09-06
Abstract: A data-handling system primarily for eliminating hidden inconsistencies from a design of e.g. an aircraft control system comprises an input terminal and a database 5 on which the design is stored as it evolves. Design data input from terminal 1 in English is analysed into simple subject-verb- object sentences by a language analyser 2 and stored as a potential design update on database 3. The potential update is then analysed by a mathematical method derived from flow algebra for consistency with the design on database 5 and added to that database or rejected accordingly. <IMAGE>

Patent GB-2128704-A (GB)
Title: Rod coupler
Inventor: KUMAR DR ARVIND
IPC: F16B4/00
Filed: 1983-10-11
Abstract: A technique of coupling bars 10 is characterized by progressively reducing the diameter of the bars in calculated steps and correspondingly increasing the wall thickness of the coupler 11. Conventional couplers have an outside diameter of about 1.5 times that of the bars. With this technique the outer diameter of the coupler can be reduced to about 1.3 times that of the bars. Reduction in the outer diameter will allow such couplers to be used extensively in reinforced concrete work for joining reinforcing bars. <IMAGE>

Patent GB-2271815-A (GB)
Title: Device for reducing pressure oscillations in a pipe
Inventor: SOTHERAN ARTHUR
IPC: F02K1/82
Filed: 1985-08-01
Abstract: A device (15) for reducing the amplitude of pressure oscillations occurring in a pipe, such as those associated with the phenomen of 'buzz' in the jet pipes of reheated gas turbine engines, comprises a cylinder (20) in which a piston (19) resides. The cylinder (20) is, on one side, in open communication with a jet pipe (14) of a reheated gas turbine engine (10) and on the opposite side in communication with a plenum chamber (22) with provides a pressure proportional to the mean pressure in the jet pipe (14). If the magnitude of pressure oscillation in the pipe (14) exceeds a set value the piston (19) is displaced enough to uncover at least one bleed port (26) which allows a passage for gas in the pipe (14) to vent to a region of lower pressure. The piston (19) is acted on by a spring (21) to avoid spurious bleeds. <IMAGE>
