Title: Improvements in and relating to control switches for electric motors
IPC: B60L15/20
Filed: 1933-04-06
Abstract: 417,396. Actuating controllers. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitõts-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) April 6, 1933, No. 10326. Convention date, April 6, 1932. [Class 38 (iii).] A controller is actuated in steps by electric driving means 1 under the control of a hand or foot operated lever 9 which actuates a contact 13 to release restraining means 2 to render the drive effective, and is coupled to the controller so as to be capable of operating it directly if the electric drive fails. The lever 9 first operates a switch 18, to energize the operating electromagnet 1, and also a valve-controlling electromagnet 5, the valve 2 being closed to prevent the flow of damping fluid in a tube 3 and to hold the controller stationary. When the contact 13, operated by the lever 9, leaves a contact 12 to de-energize the electromagnet 5, the valve 2 opens, and the controller is moved until it has operated the contact 13 into re-engagement with the contact 12 to energize the electromagnet 5 and reclose the valve 2. Thus the controller may be electromagnetically operated in steps, but if this drive fails a nose 16 on the lever 9 engages a disc 8 and the controller may be moved directly by the lever.

Title: Electrical speed regulating arrangement for an alternating- current motor
IPC: H02P25/14
Filed: 1974-03-08
Abstract: 1464792 Automatic control of speed ROBERT BOSCH GmbH 8 March 1974 [10 March 1973] 10406/74 Heading G3R [Also in Division H2] The speed of an A.C. motor, forming one arm of a bridge, is regulated by a capacitor which charges through a transistor in dependence upon the bridge diagonal voltage. The armature current, and thus the motor speed, is controlled in dependence upon the capacitor charge by a semi-conductor switch connected to the capacitor through a signal transmission device e.g. a light link. As shown, the motor, which comprises an armature 12, series field winding 11 and armature winding 10, forms one arm of bridge 12, 15, 16, 17, 18. Control capacitor 193 charges from a fixed voltage, across Zener diode 194, at a rate dependent upon the bridge unbalance i.e. any motor speed error, the motor armature voltage being speed-dependent. Provided the motor speed error is not in a given range i.e. the base emitter threshold of transistor 190 is exceeded, capacitor 193 charges through the transistor, and discharges through lamp 220 so as to vary the resistance of photo-resistor 221. The charging rate of capacitor 250 is thus varied to vary the firing angle of triac 252, in series with the motor armature, and thus regulate the motor speed. For large speed errors, the resistance of photoresistor 221 falls, to limit the motor speed to a value that is independent of the motor supply 13. Capacitor 18 in the bridge compensates for motor inductance and filters out armature voltage harmonics. The transmission device 220, 221 may be replaced by a photodiode - phototransistor or by a magnetic coil and modistor. In other embodiments Figs. 3 and 4 (not shown) capacitor 191 may be supplied by the rectified output of a transformer fed from the motor supply 13 or from the voltage across motor field 11, rather than from the, load dependent, armature voltage.

IPC: B23P17/06
Filed: 1934-04-09
Abstract: 422,096. Shearing. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.- (Rhodes, J. H.; 153, West Austin Avenue, Chicago, U.S.A.) April 9, 1934, No. 10660. [Classes 83 (ii) and 83 (iv)] In the manufacture of steel wool, the wool in the form of parallel strands is cut into lengths as it leaves the machine in which it is made. The strip of wool 10 passes from the machine through bent wire guides 17, 18 to feed rolls 19, 20, whereof the lower is driven by a belt 24 whilst the upper is pressed against the lower by levers 28 and springs 29. The roll 20 is driven so as to feed the wool slightly faster than the rate of delivery of the machine, the yielding support of the roll 19 allowing slip to take place. The wool passes from the feed rolls over the edge of a fixed shear blade 21, Fig. 4, and is cut off at intervals by a moving blade 22 attached to wheels 30 on a shaft 31. Guides 39 on the wheels wipe past the blade 21 with a small clearance to maintain the wool in contact therewith. The shaft 31 is driven from the feed roll shaft 23 by means of a belt 32 and stepped pulleys 33, Fig. 2, so that the speed of the wheels 30 and therefore the length of wool strip cut off may be varied. The pulleys 33 are connected to the shaft 31 through a hand-operated clutch 35. The machine is arranged so that fine wool is fed to one side of the machine and coarse wool to the other side, as shown in Fig. 2, the cutting apparatus being identical at each side of the machine except that the cutter wheels 30 at one side are driven independently by a separate belt 41 and clutch. The feed rolls 20 are both attached to the same driving shaft 23.
