Abstract: 771,615. Paper &c. tubes. GEE MANUFACTURING CO., Ltd. Dec. 12, 1955 [Sept. 15 1954], No. 26707/54. Class 99(2) In a machine for making paper &c. tubes by winding strip material 11 helically on a mandrel 10 by means of an endless belt 12 looped around the mandrel and driven from rollers 13, 14 and cutting the tubing thus formed, the diameter of the tubing is adapted to be varied during production thereof while maintaining constant the length of tube severed, so as to compensate for variations in the characteristics of the strip material and in the performance of the machine. The outer cover of the tube may bear a unitary pattern in which case the variation may enable the point of severance to be located accurately relative to the pattern. As described, the mandrel 10 has a slight taper (1 in 1000) and is adjusted axially; alternatively, the mandrel may be inflatable and may be in the form of a distensible helix or it may be composed of segments with internal wedging means, whereby the diameter may be varied. The mandrel 10 in the Figure is fitted with a sleeve 10a slidable in a,bearing comprising a body 21 and a cap 21a and supporting a screw rotation of which traverses a nut 23 having an extension engaging a slot in the sleeve 10a. In a modification, the mandrel 10 slides in a head mounted in an arcuate guideway, and a bevelled pinion on the mandrel engages an arcuate rack whereby axial movement of the mandrel is accompanied by angular displacement thereof to compensate for lateral displacement of points on adjacent convolutions of the strip; cutting is effected by a rotary cutter operation of which is controlled by a target, by a measuring roller riding on the tubing and actuating a switch, or by synchronizing the tube winding mechanism drive with the cutter mechanism. According to the Provisional Specification, the mandrel has a taper of 1 in 4000.

Abstract: 616,969. Clocks. JORGENSEN, C. Oct. 19, 1945, No. 27457. Convention date, April 2, 1943. [Class 139] In a rotary or torsion pendulum clock the pendulum is formed by a thin torsion wire fixed at each end and carrying at its centre a bob. As shown in Fig. 1, a torsion wire 10 is clamped at its ends by members 12 and 14 mounted on springs 20 and 24 respectively carried by a fixed plate of the clockwork. The springs 20 and 24 serve to tension the wire 10 which at its centre carries a bob 16 consisting of two cylindrical portions 28 and 38 and adjustable weights carried on screws 54 and 56. At its ends the cylindrical portion 28 projects into recesses 30 and 32 in guides 34 and 36 respectively to prevent excessive horizontal displacement of the wire. The cylindrical portion 38 lies between the guides 34 and 36 and by co-operation with them prevents excessive vertical displacement of the bob 16. A rough adjustment of the pendulum can be obtained by altering the position of the weights on the screws 54, 56. For a fine adjustment, a spring 58 carried by the plate 22 and bifurcated at its outer end to engage the wire 10 is moved, by means of a screw 62, up or down, so altering the effective length of the pendulum. If desired, the spring 58 may carry a bimetallic strip bifurcated to engage the wire and arranged to bend away from or towards the adjacent suspension point according to the variation of temperature. A counterweight 42 may be provided to prevent overstress of the wire 10.
