Title: Improvements in and relating to the manufacture of threads, films, ribbons, tubes and like forms of polymerised ethylene
IPC: B29C39/42
Filed: 1938-02-11
Abstract: 511,054. Artificial filaments, films &c. MYLES, J. R., BACHE, L.L., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 11, 1938, No. 4416. [Class 2(ii)] Threads, sheets, ribbons, films, tubes and the like are manufactured from normally solid polymers of ethylene by introducing a hot concentrated solution of the polymer in an organic solvent or a mixture of such solvents into a precipitant liquid which is miscible with said solvent or solvents but which has little or no solvent power for the ethylene polymer, the said precipitant liquid being maintained at a sufficiently high temperature, for example 70-180‹C., to ensure the precipitation of the polymer incoherent form. Suitable solvents for the polymer are benzene, tetrahydronaphthalene, decahydronaphthalene, trichlorethylene and high boiling petroleum ether. Suitable precipitant liquids are n-butyl ether, anisole, ethyl-iso-amyl ether, n-propyl alcohol, n-butyl alcohol, cyclohexanol, ethylene glycol secondary octyl alcohol, methyl amyl ketone, acetophenone, amyl acetate, methyl oleate, butyl phthalate and methyl succinate or mixtures of two or more of these liquids. Any residual liquid adhering to the materials after they leave the precipitant may be removed by the aid of a hot air blast or by the application of a partial vacuum. In cases where precipitants. of low volatility are employed, the materials may first be passed through a bath of low boiling solvent such as ethyl ether or petroleum ether. The strength of the products may be increased by subjecting them to drawing in the case of threads and tubes or to cold rolling in the case of films, sheets or ribbons. In examples, a 40 per cent. solution of ethylene polymer in xylene at about 95‹C. is (a) extruded in thread form into a bath of n-butyl alcohol or a mixture of n-amyl alcohol and butyl phthalate at the same temperature, (b) cast in the form of a film on the surface of a heated revolving drum dipping into a bath of n-propy alcohol at 90‹C. Specification 479,804 is referred to.

Title: Improvements in and relating to machines for filling receptacles with liquids
IPC: B67C3/20
Filed: 1921-02-09
Abstract: 181,061. Powley & Sons, Ltd., R., and Powley, M. Feb. 9, 1921. Bottling.-In a machine for filling bottles &c. with aerated water &c. and provided with means for delivering a determined quantity of syrup through a. valve to a series of troughs and thence through pipes to the receptacles, each pipe is surrounded by a reciprocating telescopic tube member which is moved positively outwards relative to the pipe to form an extension thereof for introduction into the receptacle during filling and is moved inwards clear of the receptacle when it moves to a further position. Measured quantities of syrup are delivered to troughs 33, from which depend outlet tubes 34 each surrounded by a telescopic tube 36 connected to a cross-head 39, which slides on a hollow guide 38 and carries, by a pin-and-slot connection, a centring-cap 37 through which the tube 36 projects. Movement of the cross-head 39 is controlled by a link 42, which connects it to a bellcrank lever pivoted at 46 to a rotating frame and provided with a roller 44 running on a cam-track 45. When the cross-head descends, movement of the cap 37 is stopped by the bottle, but the tube 36 continues to descend into the mouth of the bottle. Syrup is delivered by a valve 32 operated by a star-wheel 50 controlled by a wheel 51 at the top of a rod 52 slidably mounted in the guide 38. If no bottle is.in situ, the cross-head 39 descends below its usual position and strikes pins 53 on the rod 52, which pins project through slots in the guide 38, and so lowers the wheel 51 and prevents it from striking the star-wheel 50, a spring 55 subsequently returning it to its normal position. Specifications 23077/14, [Class 106 (v), Measured quantities &c.], and 180,280 are referred to.

Title: Improvements in devices for feeding granular and other similar materials
Inventor: CROFT ARTHUR
IPC: F27D3/00
Filed: 1952-02-25
Abstract: 721,294. Step-by-step conveyers. CROFTS (ENGINEERS), Ltd. Jan. 19, 1953 [Feb. 25, 1952], No. 4882/52. Class 78 (1). A device for feeding metal swarf, such as borings, turnings, grindings or other metal from machining operations from a vertical chamber 14, Fig. 1, to a cupola furnace 9 comprises an inclined feed passage 1 so constructed that the material entirely fills it and a reciprocating ram 4 of less cross-sectional area than the passage which is provided with projections 5, Fig. 2, to stir the material on the return stroke and prevent choking of the passage. The side walls of the passage converge from the bottom of the chamber 14 to an intermediate point 2 and thence diverge to the outlet 8. The ram is composed of parts having different diameters and is connected to the piston rod 18 of a double-acting cylinder 16. A housing 17 connecting the chamber 14 and cylinder contains adjustable stops 20, 21 which limit the stroke of the ram. These stops are engaged by a bar 22 mounted on the ram which carries at one end a double spring-loaded double-headed pin 28. This pin actuates tappet valves 26, 27 to reverse the airflow to the cylinder ends through the pipes 23, 25. The valve 26 is connected also to a dwell valve 31 and an adjustable bleeder valve 33 to cause a dwell at the end of the return stroke. Should excessive resistance to the movement of the ram occur, it will stop automatically and resume its reciprocation when the resistance is reduced. The airflow through the valve 31 is regulated by a hand - actuated valve 32. When the material in the chamber 14 falls to a certain level, the resultant movement of a flexible diaphragm 34 effects the closure of a tappet valve 35 and the apparatus is stopped. This automatic control may be cut out by opening the valve 38 in the by-pass 37.

Filed: 1953-02-23
Abstract: 726,085. Valves. W.K.M. INTERNATIONAL CORPORATION. Feb. 23, 1953 [March 13, 1952], No. 4974/53. Class 135. In a lubricated gate valve having a two-part, wedge-surfaced valve gate 18, Fig. 1, slidable between opposed annular seats 16 pressed into counterbores 22, Fig. 2, in the valve housing 10, each seat 16 mounts in an annular groove 38 spaced wiper rings 42, 44 having lips 66 pressed against the gate by a flat serpentine spring 56. Lubricant under pressure is supplied through a nipple 64, passage 62, recess 58 and holes 60 into the groove 30 behind the rings and forced through the space between the rings on to the surface of the valve gate. The pressure of the lubricant acting on the annular surface between the lips 66 opposes that acting on the rear faces of the rings to reduce the force necessary to move the gate. On closing the valve, the wedge-surfaced gate parts 26, 28 are urged apart on the engagement of the part 28 by an abutment 36 to force the rings into their grooves and so provide a pumping action which ensures the wiping away of extraneous matter from between the contacting surfaces of the gate and its seat at each operation of the valve and prevents such matter being mixed with the lubricant and the washing away of the lubricant by the fluid passing through the valve.
