IPC: F16J13/06
Filed: 1963-05-17
Abstract: 1,080,075. Pressure closures. DUNLOP RUBBER CO. Ltd. May 1, 1964 [May 17, 1963], No. 19618/63. Heading F2P. [Also in Division E2] A fastening and sealing device for a closure member 10, and a surround member comprises a securing member 15 which is movable in the closed state of the closure and surround members to secure them releasably together, and sealing means 30 for location between the closure and surround members, the sealing means being expansible to provide a seal between the closure and surround members, and the arrangement being such that expansion of the sealing means 30 moves the member 15 to a position in which it secures the closure and surround members together. In the embodiment shown the closure member is a hinged aircraft door 10, with recesses 32, and the surround includes an inflatable rubber tube 30, which passes through a guide 31 in each of a number of fastening units 14 spaced apart around the door. A securing member 15, pivoted at 17, overlies the tube 30 so that when the tube is inflated by pneumatic or hydraulic pressure the member 15 enters the recess 32 to secure the door 10, further inflation of the tube 30 causing it to contact the door and thus provide a seal between the door and its surround. A switch 33 operated by the latch 15 is connected in an electrical signalling circuit which informs the pilot of the aircraft when the unit 14 is in the fastening position. To release the unit pressure in the tube 30 is released, and pressure is introduced into a chamber 34 having a diaphragm 36 so that a rod 19 secured to the diaphragm 36 slides to the position of Fig. 3 and pivots the member 15 to the releasing position through an arm 18. The member 15 is additionally held in fastening or releasing position by a spring toggle 22, and may be controlled manually by a handle 21 on the rod 19.

Abstract: Hexafluoropropene is made by pyrolysing 2-chloro - 1,1,1,3,3,3 - hexafluoropropane at 650-850 DEG  C. for 3-120 seconds.  The reaction is suitably effected in a tubular reactor lined with a metal which is inert to the acidic products, e.g. Ag, Pt, an alloy of Ni, Cr and Fe, or an alloy of Ni, Mo and Fe.  It is preferred to use the starting material in an undiluted form, but an inert gas, e.g. N2, He, may be added.  The starting material may be made by reacting carbon tetrachloride and trichloroethylene, or chloroform and tetrachloroethylene, to give hexachloropropene which is then reacted with HF in the presence of an activated anhydrous chromium oxide catalyst.
