Title: Improvements in or relating to the production of Vinyl Fluoride
IPC: C07C67/00
Filed: 1966-12-22
Abstract: 1,168,844. Plastics reactor lining; catalytic reactor. DYNAMIT NOBEL A.G. 22 Dec., 1966 [22 Dec., 1965], No. 57567/66. Headings B1F and B1X. [Also in Division C2] A reactor for use in the catalytic hydrofluorination of acetylene to vinyl fluoride contains internal surfaces which are contacted by the reaction mixture and which are composed of a synthetic plastics material inert to hydrogen fluoride under the reaction conditions. The reactor may be formed completely of the plastics material or the plastics material may be applied as a lining to a reactor made of metal such as iron or steel. Specified plastics materials are polyethylene, polypropylene, polytetrafluoroethylene, and polycondensation plastics such as polyamide plastics. At least 3 reactors of the above type may be used in conducting the process continuously by effecting the reaction in a first reactor, connecting a second reactor in series with and downstream of the first reactor when acetylene is detected in the product from the first reactor, continuing the reaction using the seriesconnected pair of reactors until acetylene is detected in the product from the pair of reactors, disconnecting from the pair of reactors the reactor which has been longer in use and simultaneously series-connecting a third reactor to and downstream of the other reactor of the pair and continuing the reaction using the new pair of reactors, this procedure being repeated to form a new series-connected pair of reactors whenever acetylene is detected in the product from the pair of reactors then in use.

Title: Improvements in or relating to load-balancing hoists
IPC: B66D1/08
Filed: 1966-12-31
Abstract: 1,101,780. Load balancing hoists. BIRFIELD ENGINEERING Ltd. 31 Dec., 1966, No. 58493/66. Heading B8B. In a self balancing hoist 20 in which the hoist drum is rotatable in a load-lifting direction upon application of fluid pressure to a chamber coaxial with the drum, the pressure causes axial movement along a ball screw of a recirculating ball nut integral with the drum, and the supply and exhaust of fluid to and from the chamber is manually controlled by a hoist controller 30. Pressurized fluid is supplied by line 72 to a flow control device 70 on the drum casing. An adjustable needle valve on the device 70 controls the flow via line 78 and a check valve to the controller 30. Manual depression of a lever 126 on the controller opens a spring poppet valve and fluid passes to the drum operating pressure chamber via line 86 and another adjustable needle valve on the device 70. The fluid is exhausted from the chamber to atmosphere by manual depression of lever 136 which opens a further spring poppet valve in the controller 30. The movable stem in the fluid supply poppet valve is dimensioned to permit only a small flow of fluid upon partial depression of the lever 126, facilitating fine control of the drum motion. This feature may be extended to the exhaust poppet valve. A cable 102 supports the controller 30 from the hoist casing. In operation, the load is approximately positioned by means of the controller 30, in which position the load is counterbalanced by the fluid and final positioning of the load is carried out manually.

Cutter 16 is positioned at the outer edge of the stationary disc 4 and cuts each filament issuing from each orifice once per rotation of the spinneret into a length approximately equal to the circumference of ring 8-1. Above the cutter is positioned an air line 18 which blows the bundles 19 of filaments down a shoot 17 below the cutters. Preferably the ring 8-1 rotates more slowly than the spinneret; it may rotate, however, in either direction.
