IPC: D04H11/04
Abstract: 1,143,808. Corrugating webs; making pile fabrics; coating webs. PAERSE-LAING Ltd. 25 Oct., 1967 [18 Aug., 1966], No. 37014/66. Headings D1K, D1L and D1S. A corrugating machine of the type in which a fibrous web 40 or a sheet of yarns or threads is fed to a table 23 constituted by one run of an endless conveyor 16 composed of transversely-extending blades 17 into the gaps between adjacent pairs of which the web 40 is pressed to form corrugations 55, is characterized in that the conveyor 16 is guided over rollers 14, 15 so that the table 23 is inclined at an angle of between 40‹ and 85‹ to the horizontal. As shown, the table 23 is inclined at approximately 60‹ to the horizontal and the blades 17 are shaped to interengage to form the conveyor 16, see Fig. 2. A bar 28 is mounted on arms 29, Fig. 4, swingable so that the bar is caused to enter the gap between two adjacent blades 17 to form a corrugation 55 in the web 40. The arms 29 are carried on a shaft 30 oscillated by a cam (not shown) on a main shaft 34 through a link 32 and an arm 31. A supply roller 39 over which the web 40 passes is rotated stepwise by the shaft 30 through an arm 35, a link 36, and drive crank 37 and a pawl and ratchet mechanism 38. One end of the shaft 41 of the roller 14 is driven by an eccentric 46 on the shaft 34 in synchronism with the oscillation of the bar 28 through a cup 45, a rod 44 and a sprag clutch 42. The amplitude of each partial rotation can be altered by adjusting the eccentricity of the eccentric through an adjustable union 47. The other end of the shaft 41 is provided with an index mechanism comprising a wheel 48, Fig. 5, having peripheral notches 49 cooperating with spring-loaded rollers 50, 51 which, when the shaft 41 is being rotated, tend to cause it to become stationary and which are limitedly adjustable around the wheel 48. In operation, the web 40 is supplied by the roller 39 to table 23 just in advance of the bar 28 and each time the conveyor 16 becomes stationary the bar 28 forms a corrugation 55. As the table 23 progresses the corrugated web 40 passes beneath a feed box 25, Figs. 1 and 2, having an outlet 26 to provide a coating 56 of a curable substance, e.g. latex or polyvinyl chloride, on the web 40. The box 25 is supplied from a reservoir 27 by a pump (not shown). The web 40 then passes through an infra-red heating unit 24, Fig. 1, to cure the coating 56 to form a continuous pile fabric 58. If the web 40 is a yarn sheet, the pile is composed of yarn loops which may be cut or cropped to provide a tufted finish.

Apparatus for assembling and pressing the laminations of transformer magnetic circuits comprises an angularly, movable base 1 carrying an assembly table 2 having supports 5, 6 for the yokes and limbs of the magnetic circuit, a movable pressing beam 8 and drive means 11 for moving the beam towards the table so as to compress the laminations. The supports 5 comprise transverse beams carrying jacks 7, which adjust the height of the yokes. After the laminations have been positioned on their supports, bars 9 are inserted in sockets (10) and the beam 8 is mounted on the bars, Fig. 2 (not shown). The drives 11 are actuated to compress the laminations and a carriage 12 on the beam 8 is moved to a first clamping zone. The carriage is provided with means (15) for applying local pressure to the laminations, where a bandage is wound therearound, Fig. 4 (not shown). A gas burner (18) on the carriage secures the bandage end by welding and a knife (20) cuts off the loose end. The carriage 12 is moved along the beam 8 to apply bandages to the limb at preselected locations. When the laminations of the first limb have been clamped, the beam is positioned over the next limb and the cycle repeated. For pressing yokes carrying brackets or other projections, extensions 23 are fitted on to shoes 17 on the beam 8 and attachments 24 are fitted into the bars 9. The beam is turned through 90 degrees and located above a yoke, which is then clamped at pre-selected locations. Yokes fitted with brackets receive clamps, which embrace only half the yoke perimeter. The length of the beam corresponds to the maximum limb length of the circuits to be assembled on the stand. Hence it may be necessary for the beam to be placed first over one half of the yoke and then over the other. When clamping of the circuit is complete, the base 2 is pivoted to a near vertical position and the circuit removed.

As shown Fig. 1 the test wheel 9 is rotated by a feeler 14 resting against a tooth surface, carried by a nut 13 driven by motor 11 via lead screw 3. A disc 4 with two similar sets of circumferential marks is freely mounted on the shaft 2 of wheel 9 and rotated by a motor 7, the marks being sensed by a fixed head 5, whose output frequency f 5  is proportional to the speed n 4  of disc 4, and by a head 6 attached to the shaft 2 whose output frequency f 6 + is proportional to n 4  Œ n 2 , where n 2  is the speed of shaft 2 and wheel 9. The lead screw 3 is coupled by gears 15, 16 to the rotor of a selsyn 8, whose stator is fed with the signal from head 5 after it has been split into quadrature voltages at 17 Fig.2. It is shown that if the ratio of gears 15, 16 is correctly chosen, and any faults in the gear ratio and in the lead screw 3 are negligible, the frequency f 5 + of the signal from the rotor of selsyn 8 is theoretically equal to the frequency f 6 + of the signal from head 6. These frequencies are compared at 18 and the difference, representing the inaccuracy of the helix of the wheel 9, is indicated at 20.

Abstract: 1326903 Crystallizing UNITED KINGDOM ATOMIC ENERGY AUTHORITY 4 Oct 1971 [21 Oct 1970] 50032/70 Heading BIG  Compounds are separated from a feed-stock by mixing a refrigerant with the feed-stock at such a temperature that the refrigerant evaporates, liquefying the evaporated refrigerant in the presence of the feed-stock, allowing the liquid refrigerant to return to the feed-stock, and removing the crystallised component from the mix. As shown sealed vessel 2, contains heat exchanger 4, a thermometer 6 and a stirrer 8. The heat exchanger 4, comprises a copper tube to which is fed at one end liquid nitrogen from container 10, whilst at the other end throttle valve 12 allows the nitrogen to escape. Vessel 2 carries two inlets 14 and 16, and an outlet 17. The vessel can be evacuated through inlet 14 via valve 18 or supplied through 14 with a refrigerant from container 24 by valve 20 and pressure regulator 22. Feed-stock is forced by compressed refrigerant gas from a container 26, into vessel 2, via a valve 27 and through inlet 16. The feedstock and compressed refrigerant gas is fed into container 26 through valves 28 and 30. Valve 32 regulates flow of material from outlet 17. A draft tube 34, assists circulation of the, contents of the vessel under the action of stirrer 8. The apparatus can be used for dewaxing lubricating fuel or crude oils, separating saturated or unsaturated fatty acids, crystallising acetic acid from a mixture of acetic acid and acetic anhydride, or crystallising paraxylene from a feed stock containing also metaxylene. The crystallisation of para-xylene is particularly described. The refrigerants may be trifluorochloromethane, dichlorodifluoromethane, ethane, or ethylene. Instead of a copper coil an extended surface conventional heat exchanger may be used.
