Title: Improvements in or relating to traverse drums for thread winding machines
IPC: B65H54/48
Filed: 1943-03-10
Abstract: 572,330. Traverse drums for thread winding machines. SCHARER, K. J., (trading as MASCHINENFABRIK SCHARER). March 10, 1943, No. 3851. Convention date, March 23, 1942. [Class 120 (ii)] The traverse drum of a thread-winding machine is formed with a common inner carrier part 2, Fig. 2, and at least three outer parts, e.g. 3, 4, 5, each of which is detachably fixed independently to the carrier part 2 leaving gaps whereby the latter is exposed between the said outer parts to form the oppositely-directed helical thread-guiding grooves 9, 10, Fig. 1. As shown the parts 3, 4, 5 are secured by screws 6, 7, 8 to the carrier member 2 fixed to the shaft 1 and at the points where the guide grooves 9, 10 merge into each other, i.e. at the points of reversal of the thread at the ends of the drum, pins 11 are arranged across the grooves to ensure correct guiding of the thread ; the pins may be fixed in the middle part 4 and project into bores in the end parts 3, 5 of the roller. At the points where the grooves 9, 10 cross, the end parts 3, 5 are provided with noses 12, 13 which project into the groove 9 in opposite directions to prevent the thread skipping from one groove into the other.

Title: Improvements in the purification of gelatine and other substances
IPC: C09H3/02
Filed: 1941-03-24
Abstract: 548,205. Purifying gelatine. PERMUTIT CO., Ltd., and HOLMES, E. L. March 24, 1941, Nos. 3981 and 6298. Addition to 528,850. [Class 121] In purifying gelatine solutions as described in the parent Specification, by removal of mineral matters by passage through a bed of hydrogen-ion exchange material, the production of acidity in the solution is avoided by using hydrogen-ion exchange material only partly saturated with mobile hydrogen ions, the remainder being basic cations. The filter bed may be obtained by treating exchange material fully saturated with basic cations with an amount of acid insufficient to effect complete replacement of the exchangeable cations with hydrogen. Calcium salts in the gelatine solution may be replaced by sodium salts by treating the filter bed before, during or after the treatment with acid with a dilute solution of sodium chloride. The filter bed is drained and washed with water before regeneration, and is afterwards washed with water at 90-120‹F. so that after draining the bed is at a suitable temperature for treatment of gelatine solution.

Abstract: 1,083,741. Hose couplings; hoses. BTR INDUSTRIES Ltd. Jan. 20, 1965 [Jan. 30, 1964], No. 4064/64. Headings F2G and F2P. A hose end unit embodies a length of flexible hose comprising a tube 14 of electrically insulating material such as polytetrafluoroethylene and an external wire braid reinforcement 15, and an end fitting 10 including a metal sleeve 11 which is disposed within the end of the tube. The reinforcement does not extend beyond the end of the tube and is gripped with the tube between the sleeve and an outer metal ferrule or clip 16, and the reinforcement and ferrule or clip are spaced from the end fitting. The end portion of the tube is surrounded by a protective sleeve 25 of insulating material such as glass fibres, and an 0-ring is positioned between the sleeve and tube to provide a fluid-tight seal. Knurling on the sleeve prevents axial separation of the sleeve and tube arid rotation of the tube on the sleeve.

Title: Improvements in or relating to the manipulation of labels in labelling machines
Inventor: ROSE ALFRED GERMAN
IPC: B65C9/14
Filed: 1950-02-17
Abstract: 694,031. Labelling-machines. ROSE BROS. (GAINSBOROUGH), Ltd. Feb. 7, 1951. [Feb. 17, 1950] No. 4106/50. Class 73. [Also in Group XVI] In a labelling machine wherein labels 18 in a magazine 19 are separated by each of four suction separators 12 (see Group XVI) on a support 11 which is rotated intermittently by a Geneva mechanism 40, 45 from a drive shaft 86, each label is carried first to an idle or detector station, then to a gumming station, and then to a station where a bottle 22 is rolled over the label. The bottles 22 are carried on a conveyer 21 past a spacing worm 23, and are each rolled across a label on a separator 12 by means of a driven belt 24 (not shown) mounted on two pulleys, the pulley opposite the separator being mounted on a spring-urged arm. At the commencement of this rolling action, the operative face of the separator is cut off from the source of suction and connected to a source of compressed air to assist the removal of the label from the separator. The gumming-apparatus comprises a roller 96 carried by a forked arm 97 arranged to slide in a pivoted slideway 98. Gum from a bath 99 is supplied by rollers 102, 101 to the roller 96. The roller 102, driven by chain and sprocket gearing from a shaft 106, is geared to the roller 96. The arm 97 is reciprocated by an eccentric 111 on the shaft 106, and the slideway 98 is rocked by a link 114 and a pivoted arm 113 which bears against a cam 117 on the shaft 106. Thus the roller 96 first rolls down the face of a label on a separator 12 to apply gum thereto, and then moves away from the separator before making its return movement.

Title: Improvements in variable gears
IPC: F16H9/12
Filed: 1922-02-14
Abstract: 202,332. Webster, N., and Philipson & Co., Ltd. Feb. 14, 1922. Expanding pulley gearing comprises a friction train as well as a belt train. A belt f passes over V driving and driven spring pulleys A, B. These pulleys are also connected by a friction pulley C, which engages the V pulleys at the same distances from their centres as the belt does. The pulley C thus takes part of the drive, and, by its movement in the line of centre, causes one pulley to open and the other to close, to vary the ratio. Reversed driving may be effected by allowing the belt to fall upon a loose ring a<6> and then deflecting it by a jockey into engagement with the pulley C, by which the belt is driven, or by inserting an idler between the pulleys C, B.

Filed: 1938-02-11
Abstract: 510,811. Cable systems. FELTEN & GUILLEAUME CARLSWERK AKT.-GES. Feb. 11, 1938, No. 4322. Convention date, Feb. 25, 1937. [Class 36] Insulated telephone cables, instead of being provided with a lead or other moisture-proof sheath are drawn into a tube which is impermeable to moisture, e.g. a steel tube formed of a number of sections welded together. The cable may be provided with a sheath of synthetic material, such as polyvinyl chloride, which is sufficiently impermeable to protect the paper insulation against moisture during the interval between manufacture and laying of the cable. Alternatively, the cable may be subjected to a drying process after installation in the tube, which process may include blowing dry air through the tube, or ventilating the tube, with or without the application of heat, e.g., by passing a current through the cable. The tube may be filled with gas under pressure so that leaks in the tube may readily be detected by a fall in pressure.
