Abstract: 140,846. Forsstrom, W. Nov. 27, 1918. Systems controlling travel for a fixed distance.-A device for manipulating forgings &c. on the feed table of a rolling mill comprises a series of oscillating jaws which turns the metal to remove scale &c., the jaws being carried by sliding members which are driven by mechanism put into action by the metal, this mechanism preferably comprising a motor control switch which is operated to reverse the current to the driving motor and simultaneously to open the main switch which has to be re-closed before the motor starts in a reverse direction to return the jaws and their carrying members' to the original position. As shown in Fig. 2, a series of jaws 9 are arranged between feed rolls 2 of a rolling mill, and the jaws are controlled by flexible links 15 attached to fixed standards 16 to assume the position shown in Fig. 2. These jaws are operated to rotate the work through 180 degrees bv a motor 13, Fig. 5, the current to which is controlled by a switch 20, which in turn is controlled by a main switch 30, and a starting switch 26 which is closed by the engagement of the work with a spring-raised arm 23, when the work reaches a predetermined position. With the switch 20 in the position shown, the closing of the switch 26 causes the current to pass through the motor 13 in the direction A to B, and also a current passes through an electro-magnet 33 which closes the switch 30, and another circuit is completed to the motor 13 via wires 38, 43, contact 45. switch arm 20, contact 52 and wire 54. A current also passes through the electro-magnet 33 via wire 38, contact 32, switch arm 30, so that the switch 30 remains closed until the arm 20 is moved to reverse the direction of current to the motor 13. During the movement of the switch arm 20 the circuit is broken, and the switch 30 opens under the action of spring 34, so that although the switch 20 is reversed, the motor is not actually driven in a reverse direction until the switch 26 is again actuated by contact of the work with the arm 23. The motor 23 drives pinions 12 which actuate racks 10 on the slides 8, to which the jaws 9 are pivoted, and the shaft 17 of the motor control arm 20 is actuated by adjustable stops 19 on the racks 10. The switch 26 may be closed by hand instead of by the work.

Abstract: 958,775. Semi-conductor switching circuits. ENGLISH ELECTRIC CO. Ltd. June 9, 1960 [June 11, 1959], No. 20036/59. Heading H3T. [Also in Division H2] In a protective relay arrangement having an operating time related to the magnitude of a unidirectional overcurrent or over-voltage operating signal, the timing means comprise a capacitor C3 arranged to be charged by the operating signal through a rectifier S3 connected in the blocking direction with respect to the polarity of the operating signal. The operating characteristic may be modified by a parallel.non-linear resistor NL and a linear resistor R7. For quick resetting, a discharge circuit including a rectifier S2 and resistor R8 and R5 may be provided. A further rectifier S1 and resistor R6 permit near instantaneous operating when the operating signal is very large and a Zener diode S4 protects the relay circuits when the signal is extremely large. The rectifiers S1 and S3 are selenium or copper oxide rectifiers and the rectifier S2 is a silicon or germanium rectifier. The operating signal is derived from transformers T2, T3 having their secondary windings connected in opposition so as to provide no resultant output under normal conditions. The transformer T3 is arranged to saturate at a lower input current than the transformer T2 so that the transformers have a resultant output under overload conditions, the output being rectified by a full-wave rectifier B1. The delayed output from the timing means is applied to a transistorized relay circuit which may be that of Specification 958,774.

Abstract: 639,058. Sewing-machines. COENEN, G. H., and DIKS, P. M. July 25, 1947, No. 20075. Convention date, Aug. 10, 1946. [Class 112] [Also in Group XXX] Straws are cut off in a single layer from a stack in a reservoir 7 and transported to a conveyer 4 immediately below the reservoir for delivery to a machine 1, 2, 3 sewing straw envelopes for bottles. The aligned straws 8, of equal length, are fed down the reservoir 7 by prongs extending through slots in the reservoir and borne on chains 9 passing over pulleys 10 driven from the sewing machine. A "cutter" device 14 comprising members 15, 16 supported by rods 19 to move vertically relatively to a frame 11 is moved with the frame across the bottom of the reservoir 7, to the position indicated by broken lines in Fig. 1, a support 12 for the straws and a pointed cap 17 for the cutter 14 moving with the frame so that a single layer of straws is trapped between the member 15 (which is covered by the cap 17) and the member 16. During this motion a bar formed with prongs and pivoted to fixed guides 13 is held by a roller on the frame 11 across the bottom of the reservoir 7 so that the prongs prevent lateral movement of the straws. An arm bearing a roller and driven from the sewing machine then engages a bridge 20 at the top of the rods 19 to depress the rods together with the cutter 14, the support 12 and cap 17 remaining stationary. During the initial downward movement, a roller 25 on an arm 24 secured to the member 16 rides on a surface 26 on a guide plate 23 carried by the frame 11 so that the member 16 turns about a pivot 18 and the layer of straws is gripped between the members 15 and 16. The member 16 is of angle section having one horizontal and one upwardly extending vertical flange so that the straws are bent upwardly at right angles in the middle. The continued downward movement of the cutter 14 brings the straws to the conveyer 4 where a member 28 moves transversely across the conveyer to fold the upstanding ends of the straws over the horizontal portions. The lower part of the guide plate 23 is shaped so that the rollers 25 permit the members 15, 16 to separate, subsequent movement of the frame 11 to the right in Fig. 1 leaving the folded straws on the conveyer 4. The rods 19 and cutter 14 are then raised, positively or by springs, and the action repeated.
