Means for loading work pieces into machines comprises a carriage having arms carrying rollers 1 and 12 engaging guide tracks 13, 19 and 20 in a frame 14 mounted to pivot on trunnions 15. The work piece is deposited in a cradle 17 from an overhead conveyer as described Specification 699,801. The cradle is supported by arms 16 and 21. The arm 21 has a cross-piece 22 engaging a cam 26 in the frame and a slot in the crank 23 rotated bv a motor. The rollers guided by the tracks position the cradle correctly with respect to the machine. The top clamp 18 is disengaged from the workpiece and the arm 16 is swung laterally, free from the work piece or to remove the work piece after the operation by pivoting the frame 14 the rollers being returned to their initial position in the tracks. The arm 16 has a roller 27 which engages a cam 28 on the frame to take the weight of the cable on its return. In an alternative form the work piece is loaded from a support 46, Fig. 3, onto a support 50 which feeds a cradle 36. The arm supporting the cradle has rollers 33, 34 engaging a curved track 31 in triangular frames 30. The arm has a pin 37 engaging a slot in a driven arm 39. The cradle and driving mechanism are rotated through 45 degrees about a horizontal axis to disengage the work piece. In an alternative form the support 46 feeds the cradle directly.

Title: Improvements in wire drawing machines
IPC: B21C1/12
Filed: 1950-06-14
Abstract: 696,130. Drawing wire. NORTON & CO., Ltd., Sir J. F., and NORTON, W. J. June 7, 1951 [June 14, 1950], No. 14840/50. Drawings to Specification. Class 83 (iv). [Also in Group XXXVII] A wire drawing machine having a number of blocks driven through magnetic clutches has means which, upon the pressing of the " Start " button or its equivalent to set the machine in operation, causes the clutches to be saturated to a value in excess of that required for normal running, such excess saturation being maintained for a short period of time during which the initial inertia and resistance to drawing through the dies is overcome. The electrical system is such that on starting up, the clutches are fully energized, and after a predetermined time lag of up to two seconds, a contactor with a mechanical timing device, or an electronic device, operates to insert rheostats in the clutch circuits to reduce excitation of the clutches. To stop the machine, the driving-motor or motors of the commutator type is or are retarded at a controlled rate, by means of a notor. driven induction regulator, until the torque of the clutches is insufficient to maintain the drawing action, whereupon the clutches are deenergized. With a fixed speed motor or motors the clutches are de-energized at a con. trolled rate until the blocks cease to draw. Limit switches in the aforesaid induction regulator ensure that when the driving motor or motors stop the regulator returns to a position between the limits to which said switches are set, such as to give an initial speed suitable for the particular wire being drawn. Upper and lower speed limit switches stop the pilot motor which operates the induction regulator when the latter reaches either of its limiting positions.

Title: Frequency Measurement or Testing
Inventor: GLAWLESCHKOFF BASILIUS
IPC: G01R23/00
Filed: 1967-04-03
Abstract: 1,188,343. Frequency testing. ENTWICKLUNGSRING SUD G.m.b.H. April 3, 1967 [April 27, 1966], No. 15099/67. Heading G1U. The frequency of an alternating voltage is tested by generating a first train of pulses, each having a duration equal to that of a corresponding half cycle of the alternating voltage, generating a second train of pulses, each pulse commencing at the beginning of a corresponding one of the first train and ending either a predetermined time after its commencement or a predetermined time after the corresponding pulse in the first train ends and respectively feeding either both the first and second trains or the second train alone to an arrangement providing an output indicative of the relative durations of corresponding pulses of the first and second trains of pulses. In one embodiment the input alternating voltage is applied to a resistor-Zener diode combination 11, 12 to produce the first train of pulses corresponding to the positive half cycles of the input, and the pulses are applied to a timing element 10, wherein they can be controllably expanded. The output signal from the element 10 is inverted at 15 to obtain pulses corresponding to the spaces in the train from 10. These pulses are expanded at 17 to a fixed width related to the minimum frequency measurable by the system. The unit 10 is then adjusted until the pulses just disappear, as indicated on an indicator at 18, and the setting of the unit 10 indicates the input frequency. In an alternative embodiment, Fig. 5 (not shown) a timing element (20) provides an output pulse train of pulses of predetermined width. These are passed together with the input pulse train from the Zener diode input circuit (21, 22) to an exclusive OR gate which produces an output when only one input is received. The element 20 is adjusted until no output from the exclusive OR gate is obtained, whereat the adjustment of the element gives the input frequency, since its output pulse is the same width as a half cycle of the input. For small inputs the resistor and Zener diode may be replaced by a Schmitt trigger in the input.

Filed: 1956-05-16
Abstract: 828,705. Control of A.C. motors. GENERAL ELECTRIC CO. May 16, 1956 [May 25, 1955], No. 15254/56. Class 38 (3). [Also in Groups XVIII, XXXV and XL (c)] An A.C. synchronous motor is energized from an oscillator, the input circuit to which receives two feedbacks, one carrying a signal from the output circuit and the other carrying a signal whose frequency is determined by the motor speed. The arrangement may be used in the system disclosed in Specification 819,992 by which a clock motor is energized by locally generated A.C. whose frequency is controlled by a synchronizing pulse derived from power mains. The oscillator comprises a transistor 11 serving as a phase inverter and energized from D.C. terminals 14, 15 which are connected to emitter 41 and collector 31 through resistors 16, 17, respectively. Coupled to its output through capacitors 28, 29 are the input circuits of transistors 12, 13 which, with diodes 35, 36 form a push-pull class B amplifier. The amplified output is fed to field coils 45, 46 of the clock motor which has a permanent magnet rotor 50. To ensure that oscillation will start feedback circuits comprising resistor 56, capacitor 57 and resistor 82, capacitor 81 are provided round the phase inverter and amplifier, and around the amplifier stages respectively. In a further feedback circuit around the entire apparatus including the motor which includes a capacitor 66 and resistor 65, signals at the motor frequency are developed in coils 47, 47<SP>1</SP>. These ensure that the motor starts in the correct direction and accelerates to a speed arranged to be that at which the clock is designed to run. It is then locked in by pulses fed to the base of transistor 11 from terminals 25, 26. As shown in Fig. 2, rotor 50 runs in a gap in core 48 which carries field coils 45, 46. Feedback coils 47, 47<SP>1</SP> are mounted on opposite legs of a further core 49 which is arranged to be effected by the rotor field, but to produce no coupling between the field and feedback coils. The equilibrium frequency of the system may be varied by varying the angle of core 49, and by appropriate choice of value of capacitors 38, 39 connected between emitters and bases of the amplifier transistors 12, 13.
