Patent GB-2046397-A (GB)
Title: A retaining rail for securing heating pipes of an under-floor heating system
IPC: F24D3/14
Filed: 1979-08-30
Abstract: A retaining rail of generally U- shaped configuration but formed as a box-profile extrusion from plastics material is described. The extrusion includes a base and side flanges the upper regions of which are solid but the base and lower regions of which are formed with elongate cavities which extend along the length of the extrusion. Cavities (20) are formed in the flanges and cavities in the base. Circular cut-outs (28) are formed in the side flanges to receive heating pipes (32) which are laid transversely to the length of the rail. The inwardly directed projections (30) grip the pipes (32) and retain them in place. The pipes are not laid in every pair of cut-outs but for example only in alternate cut-outs according to the local heat requirements so that the exposed cut- outs allow flooring compound to flow through the openings in the walls of the cut-outs into the cavities so as to assist in embedding the extrusion within the flooring compound. <IMAGE>

Patent GB-2060053-A (GB)
Title: Ignition circuits for internal combustion engines
IPC: F02P11/02
Filed: 1979-10-05
Abstract: Switching of current in the primary winding of the ignition coil is controlled by a semiconductor device (transistor 2) and means are provided for protecting the circuit from excess supply voltages such as can arise when the engine is coupled to an external power supply. The protecting means senses the current in the primary winding and when this reaches a predetermined safe upper limit, sparking is initiated to dissipate energy in the coil. Sensing is accomplished by comparison (14) with a reference voltage VREF and employing the resultant signal to terminate prematurely the pulses controlling switching of the transistor 2. Termination is by means of logic circuitry 16, 18, 20. The circuit also includes means for restricting the engine speed during overload conditions and which includes a delay means 16 which inhibits sparking for a predetermined period of time in each engine cycle. <IMAGE>

Title: Display screen photography arrangement for a monitor employing a circular-image form of frame blanking
IPC: H04N5/84
Filed: 1979-10-23
Abstract: A radiography system in which a video image 1 derived via a television camera (not shown) from an X-ray image intensifier output screen (not shown), is applied to a display monitor tube 7 and photographically recorded from the display screen 12 by a camera 11. Exposure contrast is normally controlled by measuring image brightness using a sensor 12 and controlling the X-ray tube current. Exposure results tend to vary due to display tube aging and voltage fluctuation. In the improved arrangement the optical path between display screen 12 and the camera 11, is enclosed by an optical screen 10 to exclude ambient light and the displayed image has a circular boundary 13 because the intensifier output is a circular image. The sensor 12 measures light in an image region 14 and provides contrast control by controlling the gain of a video amplifier 4 feeding the tube 7. A further sensor 16 measures the light from the blanked outer region, eg 17, to provide a black-level control via the brightness control circuit 9. The arrangement thus enables a radiographic image stored on videotape to be replayed and photographed. <IMAGE>

Title: Apparatus for Exerting Percussive Forces on Workpieces
IPC: B21J7/46
Filed: 1980-02-04
Abstract: An apparatus for exerting percussive forces on workpieces has a cylinder 1 with pistons 3, 5 therewithin, the cylinder 1 being divided by the annular piston (5) into a gas filled chamber (7) and a working fluid chamber (6), the latter chamber (6) initially being charged with a predetermined quantity of pressurised working fluid whereafter separation of the working face (8) of the piston (3) from engagement with a cylinder and face (8) exposes the piston (3) to the working fluid to produce a working stroke of the piston (3) and its rod (2). Damping at the end of the working stroke occurs when piston (3) enters a recess (9) in the annular piston (5). The volume of the gas-filled chamber (7) increases during the working cycle since the annular piston 5 moves towards the cylinder end face 8, the increase being accompanied by a fall in the pressure of the pressurised gas. The pressurised gas in the pressurised gas chamber (7) serves to return the piston 3, 5 into their end positions shown. <IMAGE>

Patent GB-2058281-A (GB)
Title: A method of lining a pipe
IPC: B29C63/48
Filed: 1980-08-19
Abstract: In a method of lining a metal pipe with a rigid thermoplastics material lining tube, an adhesive is applied to the external surface of the tube or to the internal surface of the pipe, and the tube is inserted into the pipe. An internal pressure is applied within the tube and the assembly is subjected to an axially progressive heating so that air between the tube and the pipe is expelled and internal pressure presses the tube against the pipe. Axially progressive quenching follows the axially progressive heating. The tube may be of polypropylene and its surface etched e.g. by corona discharge.

Title: Sensing hydraulic systems
Inventor: KIBBLE JOHN DUNBAR
IPC: G01M99/00
Filed: 1982-08-17
Abstract: A desired parameter is sensed for a hydraulic circuit having discontinuous load demands. A derived signal indicative of the sensed parameter is fed to processing means 7 adapted to process those portions of the derived signal associated with operational periods when the load demand is applied to the system. Fluid is drawn by a pump 2 from a reservoir and fed to a system including loads 5 and a measurement circuit 6-22 or returned to the reservoir via an unloader valve 3. The fluid pressure is sensed by transducer 6 but a processing means 7 including a comparator 20 disregards the sensed output only if the motor 10 is energised and the sensed pressure is below a predetermined level i.e. due to a discontinuous load. When the pressure falls abnormally low a shut-off device 21 and an alarm 22 are activated. <IMAGE>

Title: Adjustable structure, for example, comprising interconnected panels
Inventor: BANNISTER BRIAN CHARLES
IPC: E05D3/06
Filed: 1982-09-17
Abstract: An adjustable structure comprises two panels 24 carrying at adjacent edges respective members 11, 13, each having ribs 14 and grooves interengaging with one another after the fashion of gear teeth so that the members 11, 13, can roll relative to one another about respective axes parallel with the panel edges. Each member 11, 13, carries within a respective longitudinal passage 33 resilient spindle elements 35 disposed substantially coaxially with the member 11, 13, and resiliently displaceable, at least in part, transversely of said axis. The members 35 are held together by connecting links 46 providing hooks receiving respective resilient spindle elements 35 of the two members, slots 32 being formed in the members 11, 13, for passage of the links. The configuration of the links 46 and the spindle elements 35 is such that resilient displacement of spindle elements 35 transversely of their axes, towards one another, is necessary to apply the links to or detach the links from the spindle elements. The construction described allows quick and simple assembly of various adjustable structures incorporating such panels, whilst ensuring reliable interconnection of the panels and adjustment of the structure. <IMAGE>

Title: Joining device for hollow members
Inventor: COCKLE ARNOLD FREDERICK
IPC: F16B7/04
Filed: 1982-10-20
Abstract: Two similar hollow structural members (1, 2) are joined together end-to-end in axial alignment by an internally disposed joining means. A tension member (6) coupled by a removable pin (7) to the member (2) extends into the member (1), and there a projecting abutment at the end of the tension member (6) is urged by a jack screw (8) screwed into member (1) into engagement with the lower end of a compression member (4) which is pivotally carried at its upper end adjacent a fixed abutment (3) secured in the member (1). The small acute angle between the compression and tension members (4, 6) enables the jack screw (8) to rapidly change the tensile force in the tension member (6) which holds the two members (1, 2) together. <IMAGE>
