Title: Improvements in or relating to devices for attaching buttons to fabric
IPC: A41H37/10
Filed: 1935-07-05
Abstract: 448,589. Sewing-machines. JACKSON, L. MELLERSH-, 28, Southampton Buildings, Chancery Lane, London.-(International Button Hole Sewing Machine Co. ; 502, Harrison Avenue, Boston, U.S.A.) July 5, 1935, No. 19284. [Class 112] A machine winds a thread about the threads securing a button to a fabric in order to form a neck. The button is tilted over the end of the throat plate 49 by a tube 38 secured to a pivoted arm 37, and the needle thread is passed through the tube 38 and secured beneath the button. The arm 37 is then swung away from the button and the needle thread wound round the button securing threads by the rotation of a gear 28 on which the arm 37 is mounted. The button is again tilted by the tube 38 and the needle thread fastened beneath the button. The gear 28 rotates on a cloth plate 29 which is mounted on trunnions 47 so that it can be tilted by a treadle 63 for the insertion of the work. At the finish of the first thread fastening operation and when the needle-bar is in its raised position, an arm 75 is drawn by a spring 77 into latching engagement with a slot in the needle bar 34 and the bar is locked. The arm 75 rotates a shaft 70 to which is secured an arm 76 for disconnecting the needle bar driving arm 84 from a lug 82 and an arm 67, 66 for actuating the arm 37. As the shaft 70 turns in a clockwise direction, the arm 67, 66 turns with it and the engagement of a pin 64 and a cam 41 together with the rotation of the gear 28, brings the arm 37 into the position shown in Fig. 12. The tube 38 is thus held in a position off-set to the needle passing position while the thread which passes through it wound round the button securing threads as the gear 28 turns. The number of turns depends upon the ratio of gears 27, 28. At the end of the winding operation the shaft 70 is turned in a counterclockwise direction by a cam 18 and the arms 75 and 76 release the needle bar 34 and reconnect it with the driving arm 84 respectively.

Abstract: 1492336 APC systems INTERNATIONAL BUSINESS MACHINES CORP 11 May 1976 [30 June 1975] 19333/76 Heading H3A An APC system for reliably and rapidly assuming a #/2 phase relationship between the input, output of a phase locked loop 34 comprises a 3#/2 phase detector 40-54 responsive to an input signal at 22 and a feedback signal along 36 for providing a threshold step signal, an input signal presence detector 58, a 180 degree phase delay element 24, a phase selection switch 28 responsive to the input signal, the signal presence indicator 58 output, the 180 degree phase delayed signal and the 3#/2 phase detector output for providing at its output selectively the input signal at 22 un-phase shifted or with a phase shift of 180 degrees and a phase lock loop 34 responsive to the output of switch 28 for providing an output signal related to the phase and frequency of the input signal and which is also used as the feed-back signal. The phase selection switch 28 normally applies the un-phase shifted input signal to the phase locked loop so that its output exhibits a #/2 phase shift. But if the output exhibits a 3#/2 phase shift (an unstable condition), the 3#/2 phase detector output exceeds a threshold so as to cause a switch 30 to vary its state by applying a control signal from device 56 and the input signal delayed by 180 degrees is applied to the phase lock loop. When the phase shift is between #/2 and 3#/2, the 3#/2 detector 38 output does not affect switch 28 and the system settles to a #/2 relationship.

Abstract: 765,882. Knitting. BRITISH NYLON SPINNERS, Ltd. June 30, 1955 [July 3, 1954], No. 19555/54. Class 74 (2). A fabric knitted of a crimped yarn is patterned by knitting on a few selected needles only. an uncrimped yarn of similar material together with the crimped yarn. A relief effect is thereby produced due to the inability of the uncrimped yarn to contract with the crimped yarn and which uncrimped yarn therefore assumes a cockled appearance which is forced proud of the surface of the fabric. The yarns are composed of a synthetic linear polymer such as a polyester or a polyamide. The different material used for each yarn and the different physical characteristics of each yarn may in addition to the relief pattern effect result in a differential dye uptake effect. The pattern effect may be achieved by needle selecting Jacquard mechanism or by laying the uncrimped yarn around selected needles in a wrap thread machine and in warp knitting. Specification 742,618 is referred to.
