Title: Improvements relating to current control circuits
Inventor: HOOPER SAMUEL BRIAN DAVID
IPC: H02P7/29
Filed: 1965-01-26
Abstract: 1,058,408. Control of D.C. motors. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Dec. 21, 1965 [Jan. 26, 1965], No. 3308/65. Heading H2J. [Also in Division G3] A traction 1 motor is supplied from battery 2 through chopper regulator 3 having " on " and " off " signals applied thereto from a multivibrator comprising transistors 14, 15. When an accelerator pedal is depressed, potentiometer 7 is adjusted to charge capacitor 6, and, at the same time, the basic mark-space ratio provided by the multivibrator is set. The exponential rise of motor current is detected by senser 4, transistor 5 conducting when the strength of the current-signal exceeds the value represented by the voltage across capacitor 6. Trigger circuit 11 then causes transistor 12 to conduct whereby transistor 14 is rendered non- conductive, and transistor 15 conducts to apply an " off " pulse to the regulator 3. The battery ceases to supply current to the motor although current continues through free-wheeling diode 1a. This current declines gradually until the transistor 5 is rendered non-conductive. The current-detecting circuit thus superimposes a control upon the basic operation of the multivibrator. The charge on capacitor 6 is increased during each successive " on " period of the transistor 5 until the capacitor-voltage reaches the maximum determined by the setting of the potentiometer 7. Thus, excessive starting currents are prevented even if the pedal is initially operated directly to its upper limit. The trigger circuit 11 may be arranged so that it renders transistor 12 conductive for a certain output of transistor 5, but is only switched to the other condition when this output falls to a lower value.

In a method of making edgewisewound coils, material is removed by machining from one or both sides of a strip conductor before winding at positions corresponding to the intended inner radius of the coil bends in such a way that the thickness of the strip after bending will not exceed the normal thickness of the strip prior to bending. The strip is advanced by a mandrel T mounted on a plate 16 which forms a rounded portion of the coil during a half revolution of the mandrel. At the end of half a revolution a stop 21 engages a switch 9 to stop the mandrel in a horizontal position. The mandrel then moves horizontally until a stop 21 engages a switch 17. The switch 9 also actuates the milling machine M wherein a piston in a pneumatic cylinder 5 rotates a threaded spindle 8 via a rack 6 and pinion 7. Rotation of the spindle 8 moves a support 1 whereby pivotally mounted milling cutters 2, 3 engage the strip. The depth of cut is adjusted by screws 13 and a dashpot 24 controls the speed at which the cutters engage the strip. A second milling machine is provided when it is necessary to mill both sides of the strip. When the switch 17 is engaged, the plate 16 rotates a further half turn and the milling cutters are disengaged. The milling machine(s) M and truing device R are mounted on a pivoted support plate 15.
