Title: Improvements in or relating to wire and the like drawing mechanism
IPC: B21C1/12
Filed: 1943-01-13
Abstract: 555,933. Drawing wire. ARNOLD, J. C. (Vaughn Machinery Co.). Jan. 13, 1943, No. 605. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 13, 1943.] [Class 83 (iv)] Continuous wire drawing machines have means for regulating both the back tension and the speed of the following drum. The wire passes from one drum to the next round a pulley 11 carried on arm 12 biased by a sector and pinion 16 on the shaft of a torque motor. Also gearing with the sector is a pinion 19 controlling rheostats 18, 18a. Manually operated rheostats 17c are in series with the fields 17b of the tensioning motors 17 and the field of the tensioning motor immediately preceding the last drum 3 is also provided with a manually operated rheostat 17d associated with a manually operated rheostat 7c in the field 7b of the motor 7 for this drum. The manually operated rheostats are set to give drives as determined by calculation for theoretically perfect conditions. Each armature 17a of the tensioning motors is in series with the armature of the drive motor for the next succeeding drum so that as the torque of the motor 7 or 6 increases a corresponding increase takes place in the back tension of the wire for the dies 10 or 9 respectively. Movement of the tension arms 12 by means of the rheostats 18 controls the speed of the immediately preceding drum motors and in the case of the intermediate motor (or motors if more than three are employed) the rheostat 18a is also operated to cause the torque of the following tension rheostat motor to be correspondingly varied. The tension arm following the first drum 1 controls only a single rheostat for the field of its motor 5. In a modification all the armatures are in parallel across the mains but the tension motors have, in addition to their rheostat regulated shunt fields, additional field coils in series with the armatures of the next succeeding drum motors.

Title: Improvements relating to the control of electric blankets or the like
IPC: H05B3/34
Filed: 1947-01-09
Abstract: 632,943. Automatic temperature control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 9, 1947, Nos. 813, 814 and 815. Convention dates, Jan. 9, 1946. [Class 38 (iv)] In an electrically-heated blanket or like article of clothing a temperature-variable resistance element distributed through the blanket controls an electron discharge device which interrupts heating upon the occurrence of a predetermined high temperature. The temperature of the electric blanket or like device is maintained constant irrespective of possible local overheating or changes in ambient temperature by a test resistance distributed through the blanket and variable over a wide range with changes in temperature. Fig. 2 shows a blanket 1 heated by elements 3, 4 connected in parallel to A.C. mains 5 over the contacts of a relay 12. A test resistance 10 is provided in the blanket and is connected in one arm of a bridge circuit comprising in addition, the tapped windings 13, 14 of the supply transformer 15 and an adjustable resistance 20, an electronic discharge device 23 being connected across diagonals. On switching on, a thermostatic switch 28 closes the circuit of relay 12 after an interval sufficient to protect the device 23 until its filament is fully heated when due to the unbalance of the bridge the device 23 operates relay 12, which pulls up and closes the circuit of the heaters 3, 4. Should the blanket heat up above the desired temperature the " test " -circuit lowers the potential of the point 19 to reduce the grid voltage and switch off the heater. The blanket temperature then falls and by reason of the falling resistance of the testcircuit, the grid potential rises and thus restarts the cycle. The system continues to " cycle " in this manner and maintain a substantially uniform temperature in the blanket. Changes of ambient temperature effect the rate of the cycle to maintain the blanket temperature constant. Similarly, abnormally high temperatures due say to local overheating are prevented. Adjustment of the operating temperature of the blanket is effected by variation of the resistance 20. In a modification (Fig. 3, not shown), the resistance 20 is replaced by a fixed resistance and the variable resistance is connected in series with the "test " resistance in one arm of the bridge. In this embodiment the fixed resistance may have a negative temperature coefficient in order to compensate for changes in ambient temperature. In a further modification (Fig. 4, not shown) the heating circuit is controlled by a grid-controlled arc rectifier, the operation of which is governed by two reversely-connected triodes, one of which has its grid responsive to the out-ofbalance voltage of the bridge circuits.
