Title: Improvements in or relating to hand knitting machines
IPC: D04B39/00
Filed: 1957-03-05
Abstract: 819,686. Knitting-machines. KUENTZ, R. March 5, 1957 [April 13, 1956; Jan. 31, 1957], No. 7213/57. Class 74 (2). In a hand knitting machine, the metal support for a rectangular needle-bed 1 or 6 of a synthetic resin comprises a member 2 or 7, the ends of which engage slidably in longitudinal slots 4 or 9 in the bed, and a member 3 or 11 secured thereto and bearing resiliently on the upper face of the bed in a zone between the slots. Relative longitudinal movement between bed and support may thus take place under the influence of, say, temperature changes. The longitudinal edges of the member 2, which is resilient, have to be sprung together, to insert them into the grooves 4, and therefore tend to move to the bottoms of these grooves. The edges of the member 7 are tied rigidly together by another member 8. The upper edge of the member 11 is turned back to form a slide 13 for the cam carriage.

The fabric plies of a tyre cover are folded and consolidated on a rotary building-drum 1 by stitcher-units comprising endless resilient belts movable to and from the drum by poweroperated means. As shown, the stitcher-units are operated by a power-cylinder 6, the pistonrod 17 of which is connected to a stitcher-supporting platform comprising a cross-plate 18 bolted to a member 22 integral with a carriage 23. The latter has bevelled edges for sliding engagement in undercut keyways in a table 7 to which the cylinder 6 is fixed. Outward travel of the stitcher-platform is limited by abutment of nut 37, on rod 34 carried by the plate 18, with a stop-block 36. Each stitcher-unit support comprises a bracket 39 having a slotted base 40 slidable on the plate 18 and secured in adjusted position by a bolt 44 passing through a clamp-bar 42 which is adjustable, by means of a screw 47, along the underside of the plate 18. An upper table 53 on the bracket 39 is recessed at 54 for adjustable engagement by an L-shaped bracket 56 in the ends of the vertical wall of which are journalled aligned sheaves 58, 59. Helically-coiled endless belts 73, 74 are trained over the sleeves 58, 59 respectively. Belt 73 is adapted for operation on the plies at the edge portions of the building-drum and, as it passes over the actual edge, is depressed as shown in Fig. 2 to wipe down the overhanging flap of the ply-structure. The operative portion of the belt 74 is constrained against inward deflection and axial displacement by means of backing- rollers 76, 77 respectively. The roller 77 is carried on a pivoted arm 93 which is yieldingly urged towards the drum by a spring 98. After the first pair of plies have been operated on by the belts 73, 74, the further plies are laid down by means of a roller-stitcher 104 whilst the drum is rotated at a speed higher than that suitable for the spring-stitchers. The roller 104 is mounted on a swinging arm 106 which is swung towards the drum by means of a rocking power-cylinder 115 and returned by a coilspring 132.

Abstract: 916,337. Automatic oscillation amplitude control. NATONEK, L. March 3, 1959 [Aug. 27, 1958], No. 7359/59. Class 38 (4). [Also in Group XXXVI] The frequency of mechanical vibration of the electrode 24 of a vibrating capacitor 24, 25, Fig. 4, is determined by an A.C. source 29 in the control grid circuit of a valve 30, the output of which energizes the vibrator magnet 1. The amplitude of vibration is maintained constant by applying a constant voltage source 28 over a high resistor 27 across electrode 24 and an auxiliary fixed electrode 26, the consequential voltage changes across these electrodes, which are proportional in amplitude to the mechanical amplitude of vibration, being amplified at 31, rectified at 32, and applied negatively as a regulating voltage in series with the source 29 to valve 30. In another embodiment, Fig. 5, the electrode 24 vibrates at its natural frequency and is maintained in oscillation by positive feed-back of the voltage changes across the electrodes 24, 26. The amplitude of oscillation will increase from zero to a constant value where the linear characteristic relating available vibrating energy to amplitude intersects the non-linear characteristic relating energy required for the vibration to amplitude. The vibrating capacitor 24, 25 may be used, for example, for D.C. to A.C. conversion in a valve voltmeter.
