Title: Treatment of filamentary polyacrylonitrile
IPC: D01F6/18
Filed: 1961-08-10
Abstract: 950,661. Treating polyacrylonitrile. AMERICAN CYANAMID CO. Aug. 10, 1961, No. 28953/61. Heading B5B. [Also in Division D1] The dyeability of previously hot-stretched filaments of an acrylonitrile polymer containing at least 80% by weight of acrylonitrile is improved by drying the filaments in the gelled state at a dry-bulb temperature of 200- 260‹ F., the relative humidity falling between the lines AA and DD. Drying is continued until substantially all the water has been evolved from the filaments and the structure has collapsed. The filaments are then treated in a relaxed state in steam at 105-160‹ C. Before the drying stage, the gelled, stretched filaments may be rinsed in water. After the drying stage, but before the steam treatment, the collapsed filaments may be immersed in a reducing solution at pH less than 7.0. The acrylonitrile polymer may be a homopolymer or a copolymer of acrylonitrile with one or more mono-ethylenically unsaturated compounds, e.g. methyl acrylate, methyl methacrylate, acrylamide, vinyl chloride, vinylidene chloride, vinyl acetate, p-styrene sulphonic acid, vinyl pyridine and 2- methyl-5-vinyl pyridine. In an example, a copolymer of acrylonitrile and methyl methacrylate is extruded into aqueous calcium thiocyanate, washed, stretched in boiling water, and dried in air at 110‹ C. and relative humidity 18% until the water content is less than 1%. The filaments are then immersed in water or in 10% aqueous sodium bisulphite, heated in relaxed condition with steam at 125‹ C. and dried at 95‹ C. to less than 1% water content. The filaments are immersed for 60 minutes in a dyebath at 95‹ C. containing 1% Sevron Brilliant Red 4G, 3% ammonium acetate, and 5% retarder LAN. Dye-bath ratio is 1: 100. In a further example, filaments are immersed for 80 minutes in a dye-bath at 93‹ C. containing 2% Calcofast Wool Bordeaux BB, 4% sulphuric acid, and 5% Glaubers salt. Dyebath ratio is 1:60. Specifications 714,530 and 732,135 are referred to.

Title: Improvements in and relating to regenerative braking on electrically driven vehicles
IPC: H02P3/14
Filed: 1938-10-07
Abstract: 523,592. Control of D.C. motors. MALEY, A. W., and TAUNTON, E. M. Oct. 7, 1938, No. 29119. [Class 38 (iii)] Regenerative braking.-In traction equipment the armature circuit is opened should regeneration cease and motoring recommence due, for example, to the vehicle running on to a section of higher supply voltage. With the circuit-breaker 14 closed and the power controller " off," contacts 12 closed, regeneration is initiated by a braking controller closing contacts 13, thereby closing contactors 18, 19. The motor field 3, 4 are thus pre-excited from the supply through a resistance 21. When the voltage across the armatures 1 and 2 approaches that of the supply, contactors 9, 25 close, contactor 25 connects the fields across armature 2, and contactor 9 connects coil 7 and rectifier 8 between armature 1 and the supply. When the back E.M.F. of the motors exceeds the voltage of the supply, coil 7 is energized and contactor 5 closes the regenerative circuit, and is maintained by coil 6. Should at any time the motor armature current reverse, coil 26 in series with a rectifier 23 is energized, causing switch 15 to reverse, thereby not only de-energizing contactors 18, 19, but also energizing trip coil 27 of the circuit breaker 14. The coil 26 may itself be the trip coil of the circuit breaker 14. Specifications 430,029, 434,189, 458,132, 461,881 and 500,947 are referred to.

A selsyn system for controlling, e.g., the screw-down gear of a rolling-mill, comprises a plurality of selsyn units selectively connectible for determining the displacement of a servomotor as measured from either the last position, or a fixed zero position. As shown, a receiving selsyn 11 with A.C.-energized single-phase rotor, has its 3-phase stator winding connected via switch 42 and differential selsyn 13 to the stator of a selected transmitting selsyn 15a- 15n. If the angular position of the rotor of selsyn 11 does not agree with that of the manually-adjusted rotor of the selsyn 15a-15n selected by operation of switches 14a-14n, 14a<SP>1</SP>-14n<SP>1</SP>, a signal voltage is developed in the latter rotor which is amplified at 16, 17 to rotate motor 10 and selsyn 11 until agreement is reached. The error signal is also fed through an amplifier 23 to a first relay which operates switch 24 to transfer motor 10 to manual control at a predetermined low value of error signal, and also to a second relay which closes switches 14, 14<SP>1</SP> to compare the new position of selsyn 11  with a further selsyn 18, the difference signal being fed via amplifiers 19, 20 and motor 21 to the rotor of differential selsyn 13. Thus the combined output from selsyns 11, 13 is again zero, and any transmitting selsyn subsequently connected will determine the displacement of motor 10 from this new zero. To revert to the original zero, switch 42 is operated via selector switch 22 to replace selsyn 11 by a further, preset selsyn 43, whereupon motor 21 drives the rotor of differential selsyn 13 to its initial position. Selsyn 18 is automatically disconnected at switches 14, 14<SP>1</SP> when its output signal is zero.
