Patent GB-349292-A (GB)
Title: Improvements relating to pattern mechanism for automatic knitting machines
IPC: D04B9/38
Filed: 1930-05-19
Abstract: 349,292. Knitting-machines. SCOTT & WILLIAMS, Inc. and SWINGLEHURST, H., 366, Broadway, New York, U.S.A. May 19, 1930, No. 15342. [Class 74 (ii).] Some of the functions usually controlled by the main pattern drum are controlled by an auxiliary pattern drum which is brought into operation by a part moving with the main pattern drum while substantially at the same time the main pattern drum is rendered inoperative. The invention is described in connection with a circular machine in which the auxiliary pattern drum controls a number of the narrowing and widening operations in making heels and toes of stockings. The main pattern drum 12) is driven by gearing 121, 122, 123 and ratchet wheel 81 secured to a shaft 80; the ratchet wheel 81 is provided with a long tooth 81a so that at that part it cannot be driven by its pawl 82 until it has been rotated by other means. The auxiliary pattern drum 150 is loose on the shaft 80, but can drive the shaft by means of a spring-pressed plunger 151 secured to the shaft and an abutment 154 arranged within the drum, and can be driven from the shaft by the plunger 151 and an abutment 153. When the pawl 82 engages the long tooth 81a, the auxiliary drum 150 and a ratchet wheel 160 secured thereto have been rotated so that a pawl 161 rides off a long tooth 160a on the wheel 160 so that the pawl can drive the wheel and drum 150. The main pattern drum is restarted by the engagement of the abutment 154 with the plunger 151, the long tooth 81a moving from under the pawl 82 so that the pawl 82 can actuate the wheel 81 before the wheel 160 presents a long tooth 160a to the pawl 161.

Title: Determining the piercability of seamless metal tubes
IPC: G01M99/00
Filed: 1968-04-01
Abstract: 1,208,203. Rolling tubes. NIPPON KOKAN K.K. 1 April, 1968 [30 March, 1967], No. 15560/68. Heading B3M. [Also in Division Gl] A Mannessman-type piercer apparatus for making metal tubes, Fig. 3, comprises conical rollers 1, 2 rotating in the same direction and drawing through the roll pinch a billet 4 of hot metal. The rotation of the rollers in combination with the effect of the piercer 3 causes the billet to exit from between the rollers as a tube (rotating forging). In order satisfactorily to test the piercability of a billet it is necessary to test the billet without using the piercer or plug 3, but previously in such tests it has been the practice to run the rollers at a speed the machine would have had were a plug actually in use. With the plug out of use however the delivery rate of the tube is greater than when the plug is in use as the plug resists delivery thus resulting in an increase in the rotating forging effect which is a loosening of the structure of the billet core portion due to the rollers alone. In order to test for this forging effect alone the axis of the rollers at the billet entry side must be varied to give the same delivery speed to the billet in the absence of the plug 3 as when using the plug and the reduction ratio (i.e. the percentage reduction of cross-sectional area after working) imposed by the rolls must be varied as the billet passes through. The billet must then be examined to detect the starting point 12 of internal rupture. The reduction ratio at that point should then be found and not exceeded at the subsequent piercing operation so that tubes having excellent internal finish may be obtained. In operation a tapered billet is used as the test piece, Fig. 5, and is inserted in the roller gap without the plug 3, the taper of the billet giving a variation in the reduction ratio as the billet passes through because the variable billet diameter is converted to a fixed diameter after reduction. In other words the billet in Fig. 5, which is of uniform cross section, has that uniformity produced by passing a tapered billet through the rolls to give various reduction ratios, and the point 12, at which internal rupture starts, is the 15% reduction ratio point which in operation should not therefore be exceeded.

Abstract: 797,570. Circuits employing bi-stable magnetic elements. SIEMENS & HALSKE AKT.- GES. May 24, 1956 [May 25, 1955], No. 16111/56. Class 40 (4). In an arrangement producing an output of longer duration than a signal pulse, a core 2, Fig. 2, having a rectangular hysteresis loop is driven to one stable state by a signal pulse in winding I and has its stable state subsequently reversed by unidirectional timing pulses applied to winding II, the flux reversal due to a timing pulse producing an output in winding IV which acts in a winding V over a delay circuit comprising a condenser C1 and a resistor W1 and restores the core to the state initially determined by the signal. Output pulses are also induced in a winding III by the flux reversals due to the timing pulses and after smoothing by a condenser C2 cause a relay 4 to operate and hold, which lights a lamp 3. The relay is released by a blocking pulse applied to winding I which cancels the signal stored in the core. Rectifiers R1 and R2 suppress unwanted induced voltages. In a modification, Fig. 3, the relay circuit is decoupled from the core 2 by a second magnetic core 5. Further magnetic cores may be added in cascade where a time delay in the output circuit is required.
