Title: Vacuum bagging
IPC: B29C70/44
Filed: 1981-03-25
Abstract: A method and apparatus is disclosed for forming a vacuum bag for moulding composite articles which comprises a base 10, triangular section ribbing 12 fixed to the base and about its perimeter, a stretchable membrane 14 of elastomeric material such as silicone rubber held within a framework 16 and able to form a seal with the ribbing 12.

Filed: 1982-02-16
Abstract: For feeding sheets to, and removing them from, a cutting machine of the kind having an angularly movable jaw which closes against a fixed jaw to cut sheets, apparatus comprising arms 7 for handling the sheets which are rotated about a common axis between work stations. At a first station holders on the arms 7 pick up sheets and then carry them to a second station where they are loaded on to the movable jaw and subsequently removed from that jaw by the holders after cutting. The arms deposit the cut sheets at a third station. Sheets are held by suction at the holders. The arms 7 extend radially of a vertical rotational axis. They are supported on a hub 31 on which is a co-axial annular gear 38 rotated by a pneumatically reciprocated rack 43, the gear being drivingly connected by a ratchet wheel 42 and pawl to the hub to rotate the hub in one direction only. The arms are urged to pivot downwards by pneumatic dampers 65 but by engagement with a sloping guide rail 70 are swung upwards as they approach the second station. A lift cylinder 18 supports the arms horizontally at the second station and a further guide rail maintains them horizontal as they travel to the third station. <IMAGE>
Patent GB-2094750-A (GB)
Title: Encapsulation and release of core material
IPC: B01J20/26
Filed: 1982-03-12
Abstract: A process for microencapsulating a core material and subsequently releasing the core material by selectively disrupting the membranes of the microcapsules involves the formation of a water-insoluble semipermeable membrane, e.g., around a droplet, through formation of multiple ionic salt bonds between a polyionic polymer in the droplet and a crosslinking polyionic polymer which possesses multiple ionic groups of opposite charge. The membrane is disrupted by exposing it to a solution of competing crosslinking multivalent (preferably di or trivalent) ions and to a solution of a competing polyionic polymer of the same charge as the polymer in the original droplet. The two competing reagents may be used in admixture. The competing reagents convert the membranes into a water-dispersible or soluble gel from which is then completely disrupted by exposure to a sequestering agent.

Title: Method of producing a bifurcated pipe junction
Inventor: BUTLER PETER ANTHONY LESLIE
IPC: B21C37/29
Filed: 1982-09-17
Abstract: To form a junction for example in, or for, a branched pipe for a vehicle exhaust system, a portion of tube between its ends is formed to a D-shaped cross section by flattening an arc of the tube section against an anvil, with an arcuate die. The tube is then cut through the arcuate section, and folded back about the unsevered flat section such that the flattened portions abut. Alternatively the tube is completely severed and the two parts are placed such that their flattened portions abut. The flattened portions are then connected, e.g. by welding, and the joined ends may then be telescoped in, and welded to, a junction pipe. <IMAGE>

Title: A braking system for a cycle, specifically a bicycle
Inventor: WATKINS ANTONY TEWDYR
IPC: B62L3/08
Filed: 1983-01-21
Abstract: A cycle (pedal, motor or tri-) is provided with a braking system in which a single brake actuating member (34 or 35) is adapted to be connected to control the operation of brakes (30, 31) on both the front and rear wheels (29, 19) of the cycle. The member is shown as a manually operable lever - it could be a pedal. At least one wheel (19, 29) of the cycle is shown operatively connected to the levers (34, 35) and adapted to be actuated upon operation of either or both of the said levers via cables. The specification illustrates a number of embodiments of caliper brakes actuable by either of two cables connected respectively to levers (34, 35) (see Figures 2, 4) and various forms of lever are disclosed (see Figures 3, 5). It may be arranged that the rear brake is actuated in advance of the front brake; and that a smaller braking force is applied at the rear brake than at the front brake (see e.g. Figures 5, 6). Figure 7 illustrates an adaptor device for fitting in a conventional cable brake system to enable both brake levers to actuate both front and rear brakes. <IMAGE>
