Title: Method of and apparatus for slitting or edge trimming strip material
Inventor: LAWSON DR KENNETH THOMAS
IPC: B23D19/06
Filed: 1983-02-24
Abstract: One or more pairs of knives 2 for trimming or slitting moving strip 14 is/are mounted on a base 3 which is pivotally mounted on a sub-base 4, itself movable transversely of the process line. The lateral position of the strip is sensed by sensors 10 and the position of the strip relative to centre line of the process line is determined by a computer (not shown) which controls the lateral movement of the sub-base 4 by a hydraulic jack 9 so as to keep the strip and trimming knives in alignment. The speed V of the strip is sensed and the lateral speed VT of the trimming knives is sensed by a transducer 12. The base 3 and thus the or each pair of knives 2 is pivoted, by a hydraulic jack 8, about a pivot 11 on the sub-base 4 so that the angle ??? the knives make with the centre line of the process, tends to equal tan<-1> (VT/V) so that despite lateral movement of the knives they remain at least substantially parallel with the line of cut made in the strip. <IMAGE>

Title: Improvements relating to felt material and the manufacture and use thereof
Inventor: WOOD ERIC
IPC: D04H1/46
Filed: 1983-07-04
Abstract: The present invention relates to the provision of a filling material such as an inorganic filler in a needled felt. The resulting felt material is formed into a tube for use in a passageway lining process in which the felt material is soaked in a curable resin.

Patent GB-2131539-A (GB)
Title: Electric starting aids for internal combustion engines
Inventor: FRENCH GEOFFREY RICHARD
IPC: F23Q7/00
Filed: 1983-10-19
Abstract: The aid has a body part to be mounted in an inlet manifold of the engine. A fuel inlet is formed in the body part for connection in use to a source of fuel. A fuel vaporiser includes an electric heating element carried by the body part which in use receives fuel from the inlet. An orifice controls fuel flow from the inlet to the vaporiser and is located in or adjacent the vaporiser at a position such that the component in which the orifice is formed is heated by the electric heating element. This minimises the risk of the orifice being blocked in use by frozen fractions of fuel. The orifice is defined in a plate located in a tubular portion of the vaporiser. The plate is cup-shaped and is held in the extension by frictional engagement of a skirt portion. -

Title: Telecommunication system
Inventor: REES FREDERICK HENRY
IPC: H04M7/14
Filed: 1985-04-27
Abstract: The public telephone network is being enhanced by the inclusion of digital exchanges in what was hitherto a mainly analogue network, with digital links between the digital exchanges and also (with suitable conversion) between analogue and digital exchanges. In addition, analogue PABX's are being replaced by digital PABX's, which raises a number of problems. To deal with one problem a concentrator-expander (2,4) pair can be used, which concentrates a number of digital links (1) on to a set (3), less in number of links to an expander (4) at which the links (3) are expanded to a set of links (6) equal in number and corresponding to the first links which give access to a digital exchange (5). Signalling uses some of the time slots on the concentrator-expander links (3), so that although communication is channel-concentrated, signalling is not. Such a concentrator-expander pair, or pair gain arrangement, is system-independent. <IMAGE>

Patent GB-2178109-A (GB)
Title: Actuator
Inventor: ARNOLD DAVID WILLIAM
IPC: F15B11/076
Filed: 1985-07-25
Abstract: An actuator has a rod 12 attached to a piston 14 slidable in a cylinder 10. The rod 12 is tubular, and acts as the cylinder of a hydraulic piston/cylinder, the piston 24 of which is fixed to the cylinder 10. Both cylinders are preferably double-acting. The actuator is operated by pneumatic pressure in the cylinder 10. The hydraulic cylinder acts to damp movement of the rod 12, since liquid is displaced from one side of the piston to the other through throttle valves 36, 38. The throttle valves 36, 38 may be closable to lock the actuator rod 12 in position, and they may be arranged to remain closed if and for as long as the pneumatic pressure is insufficient to support the load on the rod. A reservoir 34 limited by a diaphragm can communicate with the hydraulic cylinder. A fluid operated spool valve 50 may be provided at the cylinder head end to control the operation of the pneumatic piston/cylinder. <IMAGE>

Title: Immobilisation of polynucleotides
Inventor: PEDLEY STEPHEN
IPC: C12Q1/6834
Filed: 1986-11-20
Abstract: The problem of immobilising a polynucleotide on a welled plastics support, such as a 96-well microtitre plate, has been overcome by the finding that a branched polyethylenimine bonds to the plate and can be bonded to polynucleotides, such as DNA, RNA or oligonucleotides, by a cross-linking agent such as glutaraldehyde. A polynucleotide present in an analyte can be assayed by binding it to the plate, probing it with a labelled complementary polynucleotide under hybridisation conditions, and detecting the presence or amount of the label. The plate is made preferably from polyvinyl chloride or polystyrene.
