The magnetic sound track is prepared from a composition consisting of 100 parts by weight Y-hematite, 35 parts polyvinylacetate, 10 or 8 parts of polyurethane resin, 140 parts methylethyl ketone, 70 parts methylisobutyl ketone and 70 parts methoxy acetate.
Patent GB-442564-A (GB)
Abstract: 442,564. Combination ranges. WHITEMAN, A., BELLABY, A., ULPH, G. E., and BUXTON, F., Derwent Foundry, Milford, Derbyshire. Sept. 29, 1934, No. 27912. [Class 126] In a combination open fire place and cooking- stove, having a central flue for the open fire and one or more side flues, the latter are controlled by a pivoted damper or dampers 17 and the former by a sliding damper 13, interengaging parts causing the side damper or dampers to open when the open fire damper is closed, and vice versa. In the construction shown, the side flue dampers 17 are pivoted at 16 and carry tongues 19 which engage inclined faces of triangular members 18 on the damper 13 as the latter is drawn forward to close the open fire flue, the tongues riding up the incline and causing the dampers 17 to be raised to open the side flues. The side flues are fully opened before the open are flues is fully closed, to avoid trapping of smoke in the upper part of the fire.

Abstract: 464,983. Knitting-machines. LACY, W., WIGFIELD, G., WIGFIELD, S., and CUCKSON, H. W. Oct. 28, 1935, No. 29659. [Class 74 (ii)] In thread-changing mechanism for substituting one or more threads for the ground thread and cutting out and trapping one thread when another is introduced, the several thread fingers are adjusted by either of two sets of cams mounted on independent axles and connected to separate operating means so that one set of cams can be advanced independently of the other. As shown in Figs. 1 and 2, cams 4, 5, having lifts set 180‹ apart, are mounted on axles 6, 7 respectively on opposite sides of a spindle 3 carrying thread feeders 2, 2a, 2b, the axles 6, 7 being operatively connected to star wheels 9, 13 respectively that can be advanced independently by pattern controlled studs as the cam ring rotates. Associated with the feeders are two thread cutting and trapping units 28a, Fig. 3, of the type described in Specification No. 446,427, which are operated by cam controlled levers 34, 35, through plungers 30, 31, blocks 32, 33, bell-cranks 29, 28 and slides 24, 25, the blocks 32, 33 being so positioned that the plunger 30 can be raised by the lever 34 or by the plunger 31. As shown in Fig. 9 the means for operating the star wheels 9, 13 and the levers 34, 35 comprises three sets of radially movable slides controlled by a pattern drum 58, two subsidiary sets, for producing hose with a striped instep, being disposed one on each side of a main set for forming all-round striping. The main set comprises two yarn controlling slides 38, 40 and a trapper slide 36 whilst each subsidiary set comprises a trapper slide 42 and a yarn changing slide 44, the trapper slides being provided with a cam rib 37 or 43 for engaging one or other of the levers 34, 35 and the yarn changing slides carrying studs 39, 41 or 45 for operating the star wheels 9, 13. For operating the main and subsidiary sets selectively, pairs of change-over slides 46, 46a ... 49, 49a are interposed in the connections between the control slides and levers 54 ... 57, operated by the pattern drum 58, the levers of each pair being coupled together by movement of a lever 68 having dogs on its under side for engaging recesses in the slides. When the lever 68 is moved clockwise, the slides 46, 48 are coupled to the slides 46a, 48a respectively so as to operate the trapper slides 36, 42 and the yarn changing slides 38, 44 of the main and one of the subsidiary sets, whilst reversal of the lever couples the slides 47, 49 to the slides 47a, 49a so as to operate through connections 64, 67, the yarn changing and trapper slides of the other subsidiary set (not shown). The yarn changing slide 40 of the main set is connected independently to a slide 76 that is operated when a dog 85 or 86 on the lever 68 is positioned in front of a slide 81 that is connected to a drum lever 84. All the slides are disconnected when the lever 68 is in the intermediate position shown. According to the Provisional Specification the yarn changing and trapper slides may also be controlled by pattern wheels mounted on a common shaft.
