Title: Reel-winding apparatus
IPC: B29C48/05
Filed: 1962-09-04
Abstract: 999,276. Winding stock; speed and tension control. CROMPTON & KNOWLES CORPORATION. Sept. 4,1962 [Feb. 28,1962], No. 33872/62. Headings DID and D1J. Cable stock S, Fig. 2, is passed round a guide wheel 75 before being wound on to a reel R. The guide which 75 is biased to the dot- and -dash line position to tension the stock but is displaceable toward the dotted line position in response to increasing tension in the stock, such movement being used to control electrical means for reducing the speed of the reel R to a value that reduces the tension in the stock to its desired value. The guide wheel 75 is carried by arms 96, Fig. 3, pivotally mounted on a screw threaded spindle 82. The spindle 82 is rotated by reversible means controlled by limit switches 156,158 at the ends of the traverse of a head plate 98 on the arms 96. The guide wheel 75 is biased to the dot- and dash line position in Fig. 2 by piston and cylinder unit 88, 90 acting on an arm 94 coupled to a track 92 on which the head plate 98 is slidable, the head plate 98 being rockable about the axis of the threaded spindle 82. Speed control. As the head plate 98 is rocked in response to any change in position of the guide wheel 75, it moves a cam 170, Fig. 3, to rock a follower arm 172 and shift a magnetic core 174 in a reactor coil 176. The field current of the driving motor is from a source L regulated by a grid controlled rectifier tube 190, the grid bias voltage of which is charged by a phase-shift network 192 which is phase sensitive to a change in the inductance output voltage of the reactor coil 176 as caused by the displacement of the magnetic core 174. The grid bias voltage controlls the current input to the motor field 188. The arrangement is such that swinging movement of the guide wheel 75 in clockwise and anticlockwise direction, Fig. 2, will cause acceleration and deceleration, respectively, of the motor 56 and hence of the reel R.

Title: Improvements in automatic systems for regulating parallel-connected dynamo-electric machines
IPC: H02J1/10
Filed: 1929-11-08
Abstract: 340,092. British Thomson-Houston Co., Ltd., (Assignees of Bany, H., and McDonald, G. R.). Nov. 10, 1928, [Convention date]. Running generators in parallel; regulation, automatic.-The voltage of and load balance between two dynamo-electric machines in parallel is maintained when generating or motoring by means which operate selectively when the voltage is not normal to vary the field of the appropriate machine only and, when normal voltage is restored, to maintain the load balance. Overload relays limit the current of each machine and reverse current relays co-operate with them to eliminate the voltage control with excessive motoring current. A voltmeter relay 6 controls high and low voltage relays 15, 11 respectively. A current balance relay 21 energizes relay 24 or 26 according as the machine 2 or 3 is generating most current or as machine 3 or 2 is receiving most current. With voltage normal a relay 33, energized only when both machines are in operation, prepares a circuit through contacts 40, 41 of the relays 11, 15 for the raising and lowering windings 13R, 13L of the field regulator of machine 3 so that 13R is energized by relay 24 or 13L by relay 26 according as machine 2 or 3 generates most current or as machine 3 or 2 receives most current under motoring conditions. With high volts relay 15 closes lowering circuits for windings 12L, 13L of the field regulators of both machines if the machines currents are balanced, but if unbalanced the lowering circuit of one machine is interrupted by the relay 24 or 26, this being the low current machine when generating and the high current machine when motoring. Similarly with low volts the relays 11, 24 and 26 control the raising circuits for windings 12R and 13R, but when generating each overload relay 27, 27<1> opens the raising circuit of the machine to which it is connected when a given current is exceeded and closes its lowering circuit; when motoring, however, this action is precluded by the relays 30, 31 which are then de-energized by the reverse current relays 34, 35. The current balance relay 21 may be arranged to predetermine any desired division of current between the machines 2, 3. Specification 265,617, [Class 38 (iv), Electric supply and transmission systems &c.], is referred to.
