Title: Improvements relating to making wrapped pattern knitted fabric
IPC: D04B9/26
Filed: 1932-03-09
Abstract: 383,840. Knitting-machines. SCOTT & WILLIAMS, Inc., 366, Broadway, New York, U.S.A.-(Assignees of Page, A. E.; Flatbush, Brooklyn, and Swinglehurst, H.; Floral Park, both in New York, U.S.A.) March 9, 1932, No. 7100. Convention date, March 13, 1931. [Class 74 (ii).] In circular machines having selectively operated striping yarn fingers, the length of wrap can be varied by means which select and hold outside the needle circle, after the selecting means have released the same, certain of the fingers chosen by the finger selecting means. The invention is embodied in a machine of the type shown in Specification 12722/13, [Class 74 (ii), Knitting &c.], and including pivotally mounted pattern yarn fingers 766, which, with the usual bobbin stand 840, are rotated in unison with the needle cylinder. The selection of the yarn fingers is obtained by means of an intermittently rotated trick wheel 800, which by engagement with either or both of reader cams 825, 825<1> operates a lifting rod 754 and positions a cam 750 to engage any one of a plurality of butts at the upper end of each finger. The trick wheel 800 also carries means for selecting those needles which are to take wrapping yarns. When a yarn finger is swung radially outwards it carries the pattern yarn in front of a stationary abutment 870, which brings the yarn into contact with the selected needles, and then passes behind a maintaining cam 763 which holds it on the outside of the needle circle until the desired number of needles have been wrapped, both members 870, 763 being mounted on the latch ring 550. The length of wrap may be varied by employing yarn fingers of different lengths, the longer fingers, when selected, being engaged and held in yarn-feeding position by the maintaining cam 763 and the shorter fingers being returned within the needle circle by springs 815 as soon as they have passed beyond the selecting cam 750. To obtain greater selectivity, the maintaining cam may be stepped and the yarn fingers, which are enough to engage the cam, formed of varied lengths. Specifications 10819/15, 196,124, 224,593, 282,640, [all in Class 74 (ii), Knitting &c.], also are referred to.

Abstract: 559.166. Coating surfaces. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). June 18, 1942, No. 8340. [Class 95] A method of applying a stiffening material in fluent condition to a shoe upper part comprises applying the stiffening material by automaticallysupplied applying means arranged to coat both sides of the shoe upper part, and thereafter mechanically forcing the applied material into the interior of the shoe upper part. A machine, for carrying out this method upon a shoe upper U comprising a toe cap T, a doubler D and a lining L, includes lower applying means 10, a presser plate 12, an upper applying means 14, a work-supporting roll 16, and jaws 330, 332 which grip the work and drag it outwardly of the machine past the applying means 10 and 14. The lower applying means comprises a receptacle 11 with a top 36 having parallel slots 38 through which stiffening composition is extruded to the underside of the workpiece. The work is held, by the presser plate 12, against sloped ridges 68, and as the work is dragged across these ridges the stiffening composition is driven into the fabric. The presser plate 12 is adjustably carried by a swinging pivoted carrier 72, and adjustment of the plate determines the thickness of the coating on the work-piece. The upper applying means 14 is mounted on the swinging carrier 72, and comprises a receptacle 160 and a beater role 172, supplied with stiffening composition through a tube 186. As the carrier 72 is lowered, stiffening composition is forced under pressure into the receptacle 160, and, when in lowered position, the beater roll 172 is rotated at high speed and, by means of the ridges 198, the composition is scraped and driven into and through the work-piece so that it coalesces with the composition applied to the opposite side. The beater roll is water cooled. The work-supporting roll 16 is driven in the same direction as the work, and may be kept clean by means of a moistened wick 312 and squeegee roll 320. When the upper and lower applying means 14 and 10 have been brought together on opposite sides of the work, the latter is dragged from between them, so as to rub the stiffening composition into the texture of the work-piece, by means of jaws 330, 332, slidably carried on reciprocable bars 350, 336,

Abstract: 731,525. Copying-telegraphy; photo-multiplier circuits. MUIRHEAD & CO., Ltd. Feb. 29, 1952 [April 12, 1951], No. 8569/51. Class 40 (3). In an arrangement for deriving a modulated carrier signal from the anode circuit of a multi-stage photo-electric multiplier cell having its cathode subjected to the incident light, the carrier signal is applied between the cathode and the first dynode which is biased so that the mean potential between it and the cathode is in the range of maximum cathode sensitivity for all signal conditions and is such that the cell sensitivity is approximately 50 per cent of maximum. In a modification, Fig. 2 (not shown), two multiplier cells are arranged in push-pull and the carrier is applied in antiphase to the first dynodes. In a further push-pull modification, Fig. 3 (not shown), the carrier signal is applied in anti-phase to the cathodes, and in this arrangement the mean potential difference between each cathode and its associated first dynode is less than that required for maximum cathode sensitivity. In the arrangement shown in Fig. 1, the carrier A.C. is applied between the cathode 1 and the first dynode 2, and the biasing D.C. source is such that the photo-electric portion operates with maximum cathode sensitivity. Additionally, the valve of the D.C. potential in relation to the potential on the second dynode 3 is such as to give the cell a sensitivity of approximately 50 per cent of the maximum so that the applied A.C. gives the cell a total instantaneous sensitivity above or below that obtained with the D.C. alone so that from the anode 4 is derived an output current of alternating form and of value proportional to the intensity of the light incident on the cathode 1. For the double-cell arrangement, the scanning beam reflected from the object passing through an aperture to a half-silvered mirror which may be adjustable or may be associated with an adjustable masking member to control the amount of light falling on the cathodes of the respective cells; Fig. 4 (not shown).
