Title: Apparatus for bending pipe
IPC: B21D9/12
Filed: 1980-05-21
Abstract: In a pipe bending apparatus in which a pipe length 4 is forced by a ram 5 over a curved mandrel 1 having a thickened end, a curved holding arm 2 supports the thickened end of the mandrel and receives the pipe bend. To enable bends of more than about 110 DEG  to be formed, the arm 2 disengagably engages the thickened mandrel end to enable the holding arm to be swung round on a turntable 38, after release of a rightward clamping load applied to a turntable support carriage 26 to forceably engage the arm with the mandrel, whereby the pipe bend 6 can be drawn off the support arm in the reverse direction. In the rotated position of the turntable, a further support arm 40 engages and supports the mandrel when the rightward clamping load is restored. <IMAGE>

Patent GB-2073084-A (GB)
Title: Swinging ram apparatus
IPC: B26F1/40
Filed: 1980-10-30
Abstract: A swinging ram press (10), as shown, for severing lengths of elongated stock such as tubing, has a ram (18) supported for swinging movement to operate e.g. a cutoff die set (24). The press (10) includes a power cylinder assembly (110) combined with a toggle link arrangement (106, 108) to produce the swinging movement of the ram (18). The relative geometry of the ram link support (20, 22) and the toggle mechanism (106, 108) coupled with the arrangement of the cylinder (110) is such that a complete ram motion cycle is carried out during a single forward or return stroke of the cylinder. The force exerted by the cylinder and toggle mechanism is not resisted either by return springs or the weight of the ram, thereby further maximizing the usable power of the power cylinder. Accordingly, one may reduce the cylinder size requirements for a given application. The mechanical advantage afforded by the toggle mechanism (106, 108) provides for a maximum force at the ram full down position to maximize the force available for the blade stroke. Cylinder size requirements are further reduced and the force of the working strokes of the ram are equalized for forward or return strokes of the cylinder by an alternative form of toggle mechanism (208, 210), Fig. 8, which compensates for the fact that the cylinder delivers less force on retraction than on extension of its output shaft. <IMAGE>

The shield 37 is laterally offset from the plate 32 so as to be spaced from the adjacent door frame surface. The free end 42 of the strip 38 projects beyond the end of the shield 37 when the door 50 is open but is compressed behind the shield 37 when the door is closed. <IMAGE>

Patent GB-811166-A (GB)
Abstract: 811,166. Capacitors. BRITISH DIELECTRIC RESEARCH Ltd. June 27, 1956 [June 28, 1955], No. 18724/55. Class 37. [Also in Group XVI] A capacitor electrode of the lacquered foiltype is made immersing a roll of foil wound with constant tension in a chemical etching solution so that one or both edges of the foil are etched away to leave projecting lacquer coatings. Aluminium, silver or tin foils coated with polyester-polyisocyanate, epoxy resin, polystyrene or polytetrafluoroethylene may have one or both edges trimmed to expose the metal before etching in an aqueous solution of a hydrohalogenic acid, preferably hydrochloric, hydrofluoric or hydrobromic acid or nitric or sulphuric acids. A mixture of two or more of these acids may be used. Reference is made to the etching of P.T.F.E. coated aluminium in solutions of trichloroacetic acid in water or methyl alcohol, in a 4 per cent solution of sodium hydroxide or a solution of iodine in methyl alcohol, of tin in a 30 per cent solution of hydrobromic acid and of silver in a 12 per cent solution of nitric acid. A wetting agent may be added to aqueous solutions. In one embodiment a 6Á aluminium foil containing 0.3 per cent iron, coated on each surface with a 3.5Á layer of polyester-polyisocyanate lacquer is wound into a roll of 8 cm. internal diameter at a tension of 50-100 gram per cm. width before being etched to a depth of 1 mm. in a 1 per cent w/v solution of hydrofluoric acid for 240 hours. After washing by immersion for 6 hours in each of four changes of distilled water, the foil is dried. The treated foil is wound with bare foil, or similarly treated lacquered foil, or one or both major surfaces may be metallized before being wound into capacitors. In another embodiment, both edges of the roll are etched. After being washed and dried, the foil is divided longitudinally to give two strips, each having one foil edge flush with the lacquer. Capacitors having electrodes exposed at opposite ends are made by winding the two strips together, or from each strip after metallizing the major surfaces. Instead of dividing the foil, one edge may be trimmed off to expose the metal. The capacitors may be covered with a few turns of thermo-plastic film such as polyethylene-terephthalate. End connections are made by soldering, either directly or to a sprayed metal layer. Examples of treatment in solutions of other concentrations are given.
Patent GB-2097514-A (GB)
Title: Flow regulating apparatus
IPC: A61M5/168
Filed: 1981-04-24
Abstract: A flow regulating apparatus particularly for use in medical administration of fluid to the body, comprises a housing (11) which has a cylindrical protrusion (20,21) at either end so that the housing may be inserted into a tube of, for example, a medical infusion set. A piece of tubing (10) within the housing extends between the protrusions and one of the protrusions is mounted on an annular disc (12) so that it may be rotated relative to the other end of the housing. This rotation which is controlled by a ratchet mechanism (17), causes the tubing to twist and thereby controls the rate of fluid flow through the tubing. The rate of flow may be controlled between a full bore rate and a zero flow rate when the tubing is twisted so that its bore is fully occluded. <IMAGE>
