Title: Process for the production of chlorinated hydrocarbons
IPC: C07C17/15
Filed: 1959-06-05
Abstract: Metal halide catalysts for chlorination processes (see Group IV(b)) comprise halides of metals of variable valency, e.g. Cu, Cr and Fe, alone or in combination with other metals such as Na or K. The catalysts are preferably used as chlorides impregnated on an inert material such as silica gel, alumina, kieselguhr and pumice. The catalyst particles may be diluted with similar but non-impregnated particles (see Specification 894,138. Specifications 853,754 and 884,622 also are referred to.ALSO:Chlorinated hydrocarbons are prepared by the gas phase reaction between an aliphatic C1-4 hydrocarbon and/or a partially chlorinated derivative thereof, and a chlorinating agent which is hydrogen chloride and/or chlorine and an oxygen-containing gas, in the presence of metal halide catalyst particles in a tubular reactor of internal diameter 1/2 inch-4 inches, the catalyst particles each having a longest dimension of not more than 2 inches and each having a total volume equal to that of a sphere of diameter one-fifth to one-seventh of the internal diameter of the tubular reactor, the residence time of the reactants in the catalyst zone being between 0.2 and 10 seconds. The oxygen-containing gas may be oxygen alone, air, oxygen enriched air, air and an inert gas, or air, oxygen and an inert gas.  The metal halide catalyst is preferably derived from a metal of variable valency, such as Cu, Cr and Fe; other metal halides, e.g. of Na and K, may be present.  The catalyst may be impregnated on an inert carrier, and the catalyst particles may be mixed with 1-3 times their volume of inactive particles.  The preferred reaction temperature is 325 DEG C-700 DEG C.  Heat may be removed from the reactor by means of a heat exchange system, e.g. a molten mixture of KNO3, NaNO3 and NaNO2. Non-chlorinated and partially chlorinated reaction products may be recycled.  In examples, CH2Cl, CH2Cl2, CHCl3 and CCl4 are prepared from methane. Specifications 853,754, 884,622 and 894,138 are referred to.

Filed: 1938-07-05
Abstract: 516,658. Delivering slivers into cans. MACKIE & SONS, Ltd., J., and MACKIE, J. P. July 5,1938, No. 19937. [Classes 120 (i) and 120 (iii)] In apparatus for delivering slivers from a yarn preparing machine into cans and switching the delivery from a full to an empty can, the conductor for guiding the sliver into the cans is moved so that the vertical plane containing its longitudinal axis is always substantially at right angles to the vertical plane containing the axis of one of the delivery rollers of the machine. The conductor may comprise a pair of side plates moved over a stationary plate. As shown the sliver conductor 6 is mounted to slide along a horizontal rod 25 arranged parallel to the axes of the delivery roller 2, 3 and is pivotally connected by a link 26 to a slide block 27 the link having a sliding connection 28 with a connecting rod 24 on a crank disc 23 driven by bevel gearing 20, 21 from a ratchet wheel 19 on a shaft 16. The ratchet wheel is engaged by a pawl 18 on a weight 15 mounted to turn on the shaft 16 and having a tail 17 supported, during delivery of sliver into a can, by a pin 13 on an arm 12 which is constantly rotated from the alarm bell motion 10 of the drawing head. When a can is full, the pin 13 leaves the tail 17 and the weight 15 falls, the pawl 18 then rotating the ratchet wheel so that the crank disc is rotated through' 180 degrees to switch the conductor 6 from a position over the full can 4 to a position over the empty can 5. In a modification the conductor moves over a slightly curved path, the connecting rod actuating a parallel motion linkage carrying the conductor. According to the Provisional Specification the conductor may be fixed to the horizontal rod which is arranged to slide in bearings and instead of the weight, a toggle mechanism or hydraulically, pneumatically or electromagnetically controlled device may be used to give a rapid switching of the conductor from one position to the other or the movement in one direction may be effected by a spring. The connecting rod may be connected directly to the conductor or through a rack and pinion or through a single long link.

Title: Improvements in pure fluid amplifier systems
IPC: F15C1/08
Filed: 1964-05-14
Abstract: 1,070,585. Pure fluid amplifiers. R.W. WARREN. May 14, 1964 [May 20, 1963], No.20033/64. Heading G3H. A pure fluid system incorporates a fluid amplifier 13 having a power nozzle 14, control nozzles 15, 16 and an interaction chamber 17. Two outlet passages 47, 48 lead from chamber 17 and are formed by a divider 27, having passage side walls 30, 31, and passage sidewalls 25, 25a, and 26, 26a. The walls 25, 26 end in cusps 33, 34 formed with the walls 43, 45 of lateral ducts 40, 41 connected to a fixed or ambient pressure. The side walls 25a, 26a lead from the other side of the ducts and are spaced to provide an increased cross-sectional area of the passages 47, 48. The apex 32 of the divider 27 is of concave shape and located opposite the power nozzle 14. With the outlet 48 unblocked and fluid supplied through control nozzle 15, flow takes place as indicated by the arrows. The vortex V3 tends to suck fluid from the passage 47 and flow through passage 48 sucks fluid from the duct 41. When the outlet passage 48 is partially blocked by a member, the velocity of fluid decreases in passage 48 and a vortex is formed between apices 34, 36 which may prevent flow from duct 41 to passage 48. The vortex V3 creates a higher pressure region which prevents flow from passage 47 to passage 48. When the passage 48 is completely blocked, e.g. when passages 47, 48 are connected to the opposite ends of a piston-cylinder device, the flow out of duct 41 from passage 48 increases and the vortex V3 increase the pressure in region 17 to force the jet towards the wall 26. Flow through passage 47 due to the movement of the piston passes out of duct 40.
