Patent GB-1051764-A (GB)
IPC: C07C7/00
Abstract: <PICT:1051764/C4-C5/1> Acetylene is recovered from thermal or electrical cracking processes (with or without oxygen) by washing with an acetylene solvent in a preliminary stage to obtain a preliminary wash liquor and a gas which is washed with a larger amount of solvent under pressure to obtain a main wash liquor, expelling acetylene from the main wash liquor and purifying the acetylene by countercurrent contact with the main wash liquor, removing from the main wash liquor a mixture of compounds more soluble than acetylene by means of steam and/or solvent vapour and contacting the resultant mixture with the preliminary wash liquor. Solvents mentioned are aqueous butyrolactone and N-methylpyrrolidone. Gas in line 1 is washed in tower 2 with solvent from line 3 and the gas in line 4 is compressed and washed in main wash tower 6 with solvent from line 7. Liquor in line 9 is passed through stripper 10 and then into degassing tower 12.  Released gases pass into the base of stripper 10.  Some acetylene leaves by line 14 and is recycled to tower 6 and pure acetylene is recovered by line 15.  More soluble gases with water and solvent vapour are obtained from tower 12 by line 16 and enter the base of column 17 to the top of which is passed preliminary wash liquor in line 29.  Gases in line 18 are water washed in tower 19 to recover solvent which is returned by line 22 to tower 12.  Stripped solvent from column 17 is partly returned to tower 2 and partly fractionated in column 25 to recover solvent in line 27, polymers being removed by line 28.

Abstract: 1,052,092. Plastic tubes. B. F. GOODRICH CO. April 7, 1964 [April 8, 1963], No. 14331/64. Heading F2P. [Also in Divisions C3 and F4] Cylindrically-shaped tub-  ing of cellular rubber may be produced by forming a cylindrically - shaped tube from a rubber or rubber-like composition containing a chemical blowing agent, e.g. by extruding said composition, supporting the tubing in the trough formed between two parallel rolls mounted for revolution in unison, heating the tubing to cause expansion and vulcanization of the expanded composition and, throughout the heating step continuously rotating the tubes whereby the tube is rotated about its longitudinal axis in tangential contact only with the rolls. Fig. 1 shows an apparatus suitable for producing the tubing. An unexpanded tube 40 containing the chemical blowing agent is placed between two parallel rolls 21 at the right-hand end of the heating chamber 41 and transported through the heating chamber between sprockets 13 and 11. The rolls 21 are continuously rotated thus causing the tube to be rotated about its longitudinal axis and preventing the flattening of the expanding tube. The heating chamber may be heated by introducing hot air through one or more openings and may be divided into zones of different temperature by suitably placed baffles.

Abstract: 1,233,224. Bag making; seaming non-metallic sheet material. WINDMOLLER & HOLSCHER. 13 Aug., 1968 [18 Aug., 1967], No. 38639/68. Headings B5D and B5K. Machine for heat-sealing continuously moving workpieces of plastics film e.g. tube sections for making bags, has a plurality of heatsealing jaw sets secured to endless conveyer chains, each heat-sealing jaw set being arranged to be energized in dependence on the machine cycle and to be de-energized by means of a timing element after a predetermined interval of time. Tubular material is cut into bag lengths S, each of which is fed at position 37 into a pair of retaining and heat-sealing jaws 8-37, mounted on conveyer chains 2, 2<SP>1</SP>. Heat-sealing begins when the workpiece enters on the lower run of the conveyer. The retaining and sealing jaws are guided by rollers in suitable guide rails and are closed by a pair 38, 38<SP>1</SP> of a series of pairs of rails, acting on rollers 89, 89<SP>1</SP> to close the heat-sealing jaws 86, 91 (Figs. 3-5, not shown). The rails 38, 38<SP>1</SP> are pivotally mounted on levers 58, 59; 60, 61 &c. and acted upon by a respective piston-cylinder unit 63-72 through a corresponding beam 82. These units are controlled by respective cams 145-154 driven by the machine which cams also operate time relays in the heating circuits, to interrupt the heating current after a pre-set time interval. Current is conveyed to the heating jaws through current collectors 101, 101<SP>1</SP> from a common neutral bar 102 and a respective bus-bar 48 of a series of bus-bars 48-57. After the heat sealing the heating jaws are separated through release of the rails 38, 38<SP>1</SP> by the piston-cylinder unit. Subsequently the retaining means are opened and the bag deposited on a delivery container. The arrangement is such that each corresponding cam, piston-cylinder unit, pair of rails and current collectors control one of a number (10 as shown) of heat-sealing jaw sets along the lower run of the conveyer and as each set leaves said control a further set is introduced at the beginning of the run, thus enabling, say 10 out of say 30, heat-sealing jaws to be operative at the same time.

In a mechanical press having an eccentric or crank drive and a pneumatically actuated friction clutch 2 and brake 3, failure of the brake actuating means causes an air-exhaust valve 17 to be opened to actuate the brake at the end of the working stroke, the valve 17 being opened by a stop 12 which rotates with the drive shaft 1 of the press, and an intermediate member 8 which is moved out of the path of the stop at the commencement of the working stroke. This movement of the member 8 is effected by a spring-biased pawl 7 on a piston 6 which is operated by compressed air from a container 5 which also releases the brake 3 and applies the clutch 2. During the working stroke a spiral groove 10 on a disc 11 on the shaft 1, engages a pin 9 on the lever 8 and rocks it downwardly. If a valve 4 is reversed at the end of the stroke the system is exhausted to atmosphere, the clutch 2 is opened and the brake 3 applied. If the valve 4 fails to operate, the stop 12 continues to rotate and engages the shoulder on the lever 8 and moves it and a piston 14 on which it is mounted to the right against the bias of springs 15, 16, thus opening the valve 17 and operating the clutch and brake.

A gas filter comprising a bed 32 supported on a foraminous plate 6 is cleaned by (a) reversing the flow of gas so that the bed 32 is fluidised and (b) simultaneously producing violent agitation in parts of the bed by releasing compressed air upwardly into the bed from near its base through nozzles at the lower ends of travelling tubes 40 which are fitted with ribbed deflector cups 41. As described, gases from a kiln enter at 14, pass down through sand or synthetic granule bed 32, and out at 15. During cleaning, nozzles and tubes 40 are moved through the bed by the rotation of hub 27, compressed air being delivered to them via pipes 61 and 24. Rakes (45, Fig. 2, not shown) are also mounted on hub 27, and smooth the bed. Plate 6 comprises a grid 19 and fine mesh 20. A plurality of the above filter chambers may be connected for flow in parallel, selected chambers being cleaned sequentially, Fig. 3 (not shown).
