Filed: 1932-04-12
Abstract: 403,070. Valve circuits. MOULLIN, E. B., 189, Morrell Avenue, Oxford. April 12, 1932, No. 10434. [Classes 40 (iii) and 40 (v).] Relates to a tuning-circuit for use in a dynatron or other valve oscillator, in which, in order to prevent the frequency from being affected by the curvature of the valve characteristic, acceptor circuits LC2, LC3 .... are tuned to the harmonics, and an inductance L in branch a forms, with the capacity C1 together with the capacities in the acceptor circuits, a rejector circuit tuned to the fundamental ; and consists in equalizing the power factors of the inductive and capacitative branches of the total circuit at the fundamental frequency by addition of a resistance P. In order that the fundamental resonance may occur when P<2>LK=1, where K=C1+C2+C3 .... , the power factor of the inductance branch a must be equal to that of the remaining branches, which are capacitative at the fundamental frequency ; and to this end a resistance P equal to 0.868 R is added as shown, where R is the resistance in each inductance coil. The values of C1, C2, C3 ... are determined by the frequencies of the fundamental and harmonics with which they are associated, and C1=K- 2.3077 ; but as an approximation the inductances belonging to the high harmonics may be reduced to permit of the use of larger condensers. The inductance in branch LC2 may be shunted by a small condenser to make that branch capacitative to the fourth and higher harmonics.

Abstract: 127,141. Fairweather, W., (Singer Manufacturing Co.). July 4, 1918 Sewing-machines ; thread-cutters and threadend holders. -- Thread-cutting mechanism, described as applied to a sewing-machine for forming points on gloves with the object of keeping the thread ends on the underside of the work, comprises a finger 18 pivotally mounted on a slide 17 and normally held in a retracted position by springs 39. The finger is formed with a point 20, adapted to be projected into the needle-thread loops c, and a knife-edged shoulder 21, and with cam-surfaces 32, 24 adapted, on longitudinal movement of the slide, to contact with fixed abutments 35, 25, to throw the finger laterally to pull off sufficient thread for a succeeding stitch and carry the knife-edge 21 into a position where further longitudinal movement of the slide causes it to coact with a fixed ledger blade 44 to sever the loops of thread on the finger. The slide is moved by a manually-operated bell-crank lever, and the time of the three stages in the operation is controlled by a stepped cam 60 on the looper-shaft acting as a stop for a hinged guide-rod 57 carried by the slide. In order to prevent the cutting movement of the slide until two or more stitches have been made at the beginning of an operation. the rod 57 is provided with spaced ribs 78, 79 of different widths and passes through an aperture in a bar 68 and a slot 73 in a plate 66 with notches 74, 75 adapted to fit the ribs 78. 79 respectively. The bar 68 is moved so as to bring the tongue 76 between the ribs and stop the longitudinal movement of the slide until a sufficient number of stitches are made. It is then moved to free the bar 57, which then slides past the control cam. On release. of the. manual control of the operating bell-crank, all the parts are returned to their initial positions by springs. The free ends of the thread are clamped at the beginning of the operation between the presser-foot, and a plain surface provided on the feed-dog.
