Title: Process for the removal of alkynes from hydrocarbon mixtures containing alkadienes
Inventor: KING RALPH WILLIAM
IPC: C07C11/12
Filed: 1963-10-25
Abstract: In the recovery of butadiene or isoprene from hydrocarbon mixtures by extractive distillation with a polar solvent, alkynes are separated by removing a side stream from the solvent stripper column, butadiene or isoprene being recovered overhead.  The preferred solvent is aqueous acetonitrile.  The alkyne-containing side stream is removed from the stripping column as a vapour or liquid at a point below the feed, preferably in the lower third of the column.  Part of the solvent bottoms may be returned to the stripper column at a point above feed entry.  The side stream may be stripped or washed with water to recover solvent and the hydrocarbons sent to atmosphere, selectively hydrogenated and recycled to the extractive distillation or recycled to a dehydrogenation process producing the extractive distillation feed.  Raffinate from the extractive distillation may also be recycled to a dehydrogenation stop.

Abstract: 952,393. Shoots; conveyers. AMP Inc. Nov. 22, 1962 [Nov. 28, 1961], No. 42432/61. Headings B8A and B8S. Electrical leads 22, each with a leading connector 23 and a trailing connector 24, are fed singly from an automatic lead-making machine (not shown) to an inlet funnel 1 (Fig. 1, plan view), driven rolls 4 mounted on levers 6 pivoted at 7 being opened by a ram 10, 11 to allow passage of the leading connector 23. The rolls 4 are then brought into contact to project the lead 22 into a channel 13 with sufficient force to reach the closed end 15, the rolls being such as not to damage the trailing connector 24. The channel 13 has a bottom plate 16 pivoted at 17 (Fig. 3) and operated by a ram 18 to allow the lead 22 to slide down a shoot 19 into a trough 20. The leads 22 are thus stacked in parallel sideby-side relationship to facilitate further handling. The sequence of operations is controlled automatically by cams mounted on a cam-shaft (not shown), driven by the lead-making machine, actuating the rams 10, 11 and 18. Specification 921,777 is referred to.

Abstract: 1,043,636. Driver alerting arrangement. T. P. DEMPSEY, and K. A. SHKARDOON. Oct. 20, 1964 [Oct. 21, 1963], No. 42752/64. Heading B7N. An alerting system for vehicle, e.g. train, drivers comprises a slow-release relay A/2 which is momentarily energized via an alert button 17A or micro-switches L7B, 17C associated with the train brake and throttle controls and which at the end of its 2 minute release time operates a lamp 14 and buzzer 15 at its contact A2 and opens the energizing circuit of relay P/1 at its contact A1, if the alert button is not operated before the termination of the 20-second release delay of relay P/1 contact P1 opens to release relay B and apply the brakes. A relay M/2 is provided to prevent permanent actuation of the alert button and is energized via one of the switches 17, if the relay is continuously energized for a period of 90 seconds it picks up and operates a horn 16 at its contact M1 and opens the brake circuit at contact M2. In a second arrangement, Fig. 2 (not shown), a train carried magnetic switch actuated by permanent track magnets operates the alert alarm on approach to junctions. Means are also described for disabling the system when the train is waiting for a long period or when a fault appears in the circuit arrangement or the air brake system.

Title: Method of and apparatus for checking whether or not a knotting cycle has been carried out successfully in the operation of a winding mechanism
IPC: B65H63/00
Filed: 1968-09-09
Abstract: 1,245,838. Checking knotting operations. ELITEX ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI. 9 Sept., 1968 [9 Sept, 1967], No. 42761/68. Heading D1D. Yarn 112 passing to a winding station is engaged by fingers 14 biassed by a spring 160 and by an arm 110 'biassed by a pivoted weight 114. In the event of yarn breakage fingers 14 and arm 110 are displaced and an automatic knotting operation performed. If the operation has been incorrectly performed and the yarn is not in the position shown, the apparatus of Fig. 1 prevents repeated knotting operations thus indicative to an operative than the station requires attention. As shown on yarn breakage fingers 14 and arm 110 are displaced. The displacement of arm 110 causes, with a time delay, a cam 4 to be driven, thus pivotting a lever 1 biassed thereagainst. The opposite end of lever I is moved clear of a member 7 pivoted on a lever 9 so as not to restrain lever 9 from rotating anticlockwise under the influence of a biassing spring. If the knotting operation has been successfully performed and the yarn is once again in the position shown in Fig. 1 an abutment 12 associated with fingers 14 engages the end 11 of lever 9 and prevents it being rotated and the winding operation then proceeds. If the knotting has not been correctly carried out and the yarn is not in the position shown abutment 12 is displaced from the position shown and lever 9 rotates anticlockwise. This prevents knotting being repeated and requires an operative to investigate the reason why the knotting mechanism is functioning incorrectly. On repairing the knotting mechanism the operative manually resets the checking mechanism.

Title: Improvements in or relating to a method for positioning a movable body with reference to a stationary body through the agency of compressed fluid and means for executingsaid method
IPC: F16C32/06
Filed: 1960-12-13
Abstract: 917,117. Fluid-bearings. MECANORGA S.A. Dec. 13, 1960 [Dec. 24, 1959], No. 42881/60. Class 12 (1). The position of a rotationally or translationary movable member supported by fluid under pressure in a fixed member is adjusted by the opening of a slidable sleeve valve arranged in the fluid circuit, thus increasing the fluid pressure. A bearing 2, Fig. 2, supporting a rotating shaft 1 has at least one chamber 3 to which fluid under pressure is supplied through a passage 11a. Diametrically opposite the chamber, a slidable sleeve valve 5 is carried by a bearing 19 secured in bearing 2 and fluid under pressure is supplied to the bore 8 of the sleeve through a passage 24 and between the head 4 of the sleeve and shaft 1. The other end of bore 8 is connected to passage 11a by a further passage 11, and also to a discharge 10 through a port 9. An adjustable port is formed by a collar 14 on the sleeve, and a ring 15 on bearing 2, and fluid passes through this port to a chamber 13, and thence to discharge 10 via a port 16. In operation, with shaft 1 coaxial with bearing 2, and an external force acting on the shaft above chamber 3, the shaft will move towards the chamber and the fluid pressure will increase, thus increasing the pressure in bore 8 of sleeve 5. Sleeve 5 will be forced away from shaft 1, and the port formed by collar 14 and ring 15 will allow fluid to pass into chamber 13 until the pressures in the latter and bore 8 are the same, whereupon the movement of sleeve 5 will cease. The pressure in chamber 3 will build up and shaft 1 will move back to its original position. Different fluids may be used for chamber 3 and the remainder of the circuit and in this case a slide valve 29, Fig. 3, is inserted between passages 11, 11a, and fluid to supply chamber 3 passes through a port 32 and is bled-off through a passage 36 and exhausted, due to movement of valve 29 when the chamber pressure is increased.
