Title: Cable making machines
IPC: D07B3/00
Filed: 1970-04-30
Abstract: 1356942 Stranding machines TRAFALGAR ENG CO Ltd 8 June 1971 [30 April 1970] 20812/70 Heading D1T A cable stranding machine of the kind in which a plurality of wires are hauled along a feed path whilst being rotated about an axis coincident with said feed path, has the resulting stranded cable passed around strand delivery pulleys before being passed to a take-up spool, the strand delivery pulleys and the take-up spool rotating about the feed path of the cable, and a differential gear mechanism that causes a relative rotary oscillation between the spool and the pulleys such as to cause the cable leaving the pulleys to be traversed back and forth along the spool. In Fig. 1 the strand delivery pulleys 13, 14 and the take-up spool 15 are driven from a common drive that includes said differential mechanism whereby a periodically reversing component of movement is introduced into the drive of the pulleys 13, 14 or the spool 15 about the stranding axis. In Fig. 5 input shaft 40, driven by motor 18, carries a bevel pinion 41 meshing with two further bevel pinions 42 carried by annular frame 43. An out-put shaft is driven by a further bevel pinion meshing with the pinions 42. The frame 43 carries an arm 44 having at its outer end a pin 45 in a slot 46 in a plate 47 carried by a threaded block 48 on a lead screw 49. The lead screw 49 is rotated by any suitable transmission and limit switches 50 reverse the direction of rotation of the screw 49 either by reversing a driving motor or by actuation of an appropriate reversing gear. The resulting oscillation of the frame 43 causes the take-up spool 15 to oscillate relatively to the pulley 14 whilst the pulleys and spool are rotating about the feed path 12. The limit switches 50 are adjustably mounted to vary the amplitude of traverse. Screw 49 may be driven at a variable preselected rate such that the cable moves axially along the spool through its own diameter for each revolution of the spool. Fig. 6 (not shown) illustrates an alternative method of causing the spool 15 to oscillate relatively to the pulleys 13, 14. An annulus (62) is driven by a belt. Bevel gears (60) on one side of the annulus (62) rotate the spool 15. Bevel gears (63) on the other side of the annulus are coupled through a gear box (64) that contains a reversing mechanism, to a motor (67) that rotates the spool 15 about its own axis.

Title: Improvements in or relating to machines adapted to insert packing material into containers
Inventor: HOLLIS ALBERT CHARLES
IPC: B65B61/22
Filed: 1955-07-20
Abstract: 832,752. Packaging-machines. B. U. SUPPLIES & MACHINERY CO. Ltd. July 19, 1956 [July 20, 1955], No. 20954/55. Class 94(1). In a machine for inserting cotton-wool or like packing material into bottles containing tablets or like articles, the bottles are fed in line between guides 42, Fig. 1, and transferred in succession by an oscillating arm 44 to pockets 36 of an intermittentlyrotating disc 40, each bottle being carried round between guides 36, 38 to an inserting station A where it is received by a holder 96, Fig. 2. The latter is carried by a rotatable and reciprocable shaft 98 which is first raised to cause the neck of the bottle to embrace the lower end 150, Fig. 5, of an inclined guide 146 down which a rope of cottonwool is fed and then rotated in 180 degree steps so that the wool is packed evenly under the shoulders of the bottle. The shaft 98 is then lowered to allow the bottle to be removed from the holder 96 by the next movement of the disc 40 and fed out of the machine between guides 50, the inserted cotton wool being severed from the rope when the holder reaches its lowered position. The cotton-wool feeding mechanism comprises a member 148, Fig. 5, pivoted to a lever 158 and a spring link 169, the lever being fulcrumed at 160 and coupled at its other end to a link 162 actuated by an eccentric 164, 166, and the link 169 being coupled at 168 to an intermediate portion of the link 162. The arrangement is such that the end 149 of the member 148 is pressed against the rope of cotton-wool by the spring on its downward stroke but retracted clear of the rope on its upward stroke, so that the wool is fed into the bottle in a series of tucks. The member 148 is operated continuously but is normally prevented from feeding the wool by a spring-loaded pivoted arm 194 which prevents anticlockwise movement of the member about its pivot 156. When a bottle is raised to the position shown in Fig. 5, it actuates a microswitch 188, Fig. 2, which energises a solenoid 192 whose armature 200 is coupled to the arm 194. The latter is thus swung clear of the member 148 to allow it to engage the wool. The wool is severed from the supply by mechanism C comprising cam-operated shears 216 and 218 (see Fig. 6, not shown).

Title: A method for conditioning thin webs of a thermoplastic material to improve windability
IPC: B29C53/32
Filed: 1961-06-09
Abstract: 948,805. Embossing; winding webs; embossing surfaces. INTERNATIONAL DEVELOPMENT CO. OF NATIONAL DISTILLERS & CHEMICAL CORPORATION S.A. June 9, 1961 [June 10, 1960], No. 20982/61. Headings B6B, B6C and B6J. In the winding of webs of thin thermoplastic material into rolls the material is preconditioned so as to compensate for the effects of shrinkage and density change therein after rolling, by embossing the web to produce a regular embossed pattern on the web immediately prior to winding the web upon a roll under such conditions that distortion of the thermoplastic material in excess of its elastic limit is avoided. A web 3 of thermoplastic material, which may have a gauge less than 0.002 inch, is embossed between a resilient, rubber cylinder 4 and an engraved, chromeplated steel cylinder 5 and is then wound on a roll centre tube 2 on a winding shaft 1 after passing round a spring-biased idler roller 6. The shaft 1 and the shafts of the cylinders 4, 5 are driven in synchronism. The cylinder 5 is engraved with helical grooves 7, 8 of opposite rotation and with circumferential grooves 9 so that a pattern of equilateral triangular bosses is formed thereon, there being preferably between 64 and 1,024 bosses per square inch. The pressure between the cylinders is sufficient to impress the pattern into the material of the web 6 without exceeding the elastic limit of the material and may be within the range of 25 to 150 1b. per square inch. Thus the pattern remains impressed on the material as it is wound up but disappears after a time whereby additional material is made available in each roll layer to compensate for the effects of shrinkage and density change, preventing the formation of ridges and depressions in the rolled web.

Title: Silver chloride, silver sulphide infrared transmitting filters
Inventor: HAMMAR GUSTAF WILHELM
IPC: G02B5/22
Filed: 1953-07-31
Abstract: 898,222. Optical filters. EASTMAN KODAK CO. Aug. 3, 1954 [July 31, 1953], No. 21368/53. Class 97(1). An optical filter opaque to wavelengths of less than 2 microns is produced by immersing a polished sheet of crystalline silver chloride in an aqueous solution of hydrogen sulphide of concentration 0.01N to 0.2N for between 2 and 60 seconds and then rinsing in water and drying it. After drying, the sheet may be baked at a temperature between 100‹C. and the softening temperature of the sheet (about 455‹C.). Just before immersing the sheet in H 2 S solution it should be dipped in a wetting agent, such as any detergent not harmful to the silver chloride. By increasing the time of immersion, within the time of 60 seconds, the longest wavelength at which the filter is opaque may be increased up to 5 microns. In addition to the improvement in opacity to wavelengths of about 2 microns it is claimed that filters according to this Specification have improved transparency (curves 10, 11) at wavelengths of 11 to 13 microns. The sheet may be continuously immersed in the H 2 S solution.
