Title: Improvements in and relating to direct current electric motors
IPC: H02K23/02
Filed: 1944-01-25
Abstract: 578,636. Exciting motors. MANDL, A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Jan. 25, 1944, No. 1410. [Class 35] A motor is operated at constant speed by providing it in addition to a shunt winding, with two componentsofexcitation varying with armature current and counterbalancing one another under steady condition, but one component acting with a time lag, so that on armature current increase, a series component becomes effective to oppose the increase in current. In the form shown in Fig. 3, an exciter 6 with a field winding 7 connected across the interpole winding 8 of motor 1 is connected across the series winding 3 of the motor and renders that winding almost ineffective under steady conditions but effective when the motor armature current fluctuates. The exciter preferably also has damping windings. The series winding 3 assists the motor shunt winding 2 and the exciter winding 7 may be assisted by a series coil 10. Instead of being in parallel with the motor series coil, the exciter may supply a third motor field winding opposing windings 2 and 3, and if desired the shunt excitation may be on the exciter instead of on the motor. In such cases the motor series and opposing separately excited windings should be on different poles or separated by leakage paths. In a further modification, an inductor alternator is used as the exciter, feeding the motor field winding opposing the series coil 3 through a rectifier. The exciter may have a series choke 11 and as a further alternative may be of the metadyne type. A non linear resistance 5 may be in series with shunt winding 2 so that its current changes in greater proportion than the line voltage.

Abstract: 1,034,032. Heat-setting stretched polyvinyl chloride film. TOYO RAYON KABUSHIKI KAISHA. Jan. 15, 1964, No. 1870/64. Heading B5B. A film which consists of polyvinyl chloride or of a polymer consisting chiefly of polyvinyl chloride, and which has been formed by melt extrusion or by calendering, is stretched at a temperature above its heat distortion tempera. ture but below its melting point in either the longitudinal or the transverse direction or in both directions at a stretch ratio of not less than 2 in at least one of the directions, then heat-set under tension at a temperature within the range of from the " Critical Breaking Temperature " of the film to a temperature 20‹ C. lower than the C.B.T. and preferably at a temperature within the range of from 1‹ or 2‹ C. below and 10‹ C. below the C.B.T., followed by a second heat-setting step in which the film is relaxed in either of or both the directions to an extent within the range from 1 to 20%, at a temperature within the range of from 70‹ C. to the C.B.T. The C.B.T. is determined by holding a piece of the film in a frame in such a manner that the film is prevented from shrinking, and placing the frame in a hot air oven the temperature of which is raised at the rate of 2‹ C. per minute starting at 50‹ C. The C.B.T. is the temperature at which the film breaks. In the first heat-setting step the film is held under sufficient tension to prevent it from shrinking. In an example, a P.V.C. film meltextruded at 200‹ C. is stretched at a stretch ratio of 2À2 in the longitudinal direction at 90-95‹ C. by means of nip rolls and stretched at a stretch ratio of 2À2 in the transverse direction by means of a tenter. The critical breaking temperature of this biaxially stretched film is 134‹ C. and part of the film is heat-set under tension for 17 seconds at 130‹ C. by means of a tenter. Another part of the film is heat-set in a continuous manner under tension for 17 seconds at 130‹ C. using a continuous heat-setting apparatus comprising a set of closely spaced rolls. The portion of the film heat-set under tension at 130‹ C. using a tenter is heat set while being allowed to relax 1 to 20% at 100‹ C. and 130‹ C.

Abstract: 724,661. Automatic speed-control systems. SIEMENS-SCHUCKERTWERKE AKT.-GES. Jan. 22, 1953 [Jan. 22, 1952], No. 1893/53. Class 38 (4). [Also in Group XXXVII] In a three-phase-hoist motor-control system of the kind using a low auxiliary frequency during, e.g., braking and stopping, the excitation of the motor at the auxiliary frequency is automatically controlled to maintain a predetermined speed. As shown, a three-phase wound rotor induction motor 1 may be supplied from a main supply at, e.g., 50 cycles through " forward " or " reverse " switches 2, 3, or it may be supplied from an auxiliary supply at, e.g., 2 c/s. through " forward " or " reverse " switches 4, 5, and a motor-operated resistor 6 for varying the excitation. The hoist-motor 1 drives a tachometer-generator 14 having a three-phase field rotating in the opposite direction to the rotor, whereby the rotor output voltage varies with the speed, and there is a high output at synchronous speed. The output of the tachometer 14 is rectified at 21 and applied to the resistance-operating servomotor 28, in opposition to a reference voltage, from rectifier 22, the magnitude of which is preset by a contact arm 23 co-operating with resistors 24, 25 and mechanically coupled to the hand-control lever (not shown). The direction of rotation of the servomotor is controlled by a relay 20 according to whether the motor is hoisting, or braking an overhauling load (i.e. according to the tachometer output indicating that the motor is below or above synchronous speed) so that resistor 6 is varied in the correct direction to maintain constant speed.
