Patent GB-429843-A (GB)
Title: A new and improved rotary internal combustion engine
IPC: F02B53/00
Filed: 1933-12-07
Abstract: 429,843. Rotary internal-combustion engines. POLICANSKY, H., Tandem, Marmion Road, Cape Town, South Africa. Dec. 7, 1933, No. 34487. [Class 110 (ii)] A rotor D has two piston vanes C, C<1>, which move around a rectangular-sectioned annulus inside a stator A. Axially-sliding pairs of abutments H<1>, H<2>, J<1>, J<2> are actuated by push rods and bell-crank levers, from cams on the shaft E. Fuel gas is induced through ports L<1>, M in the casing and K in abutments J<2> when the latter are closed, Fig. 3. The vane C<1> is provided with scavenging blocks Q which close recesses P and assist the vane C<1> to sweep burnt gases through exhaust ports M<2>, L<2>. The vane C has no scavenging blocks, and gas compressed in front of the vane is transferred to the rear of it during its passing the recesses P, and the compressed fluid is fired by a plug S<1>, the abutments H<1> being closed at this moment. Gas pressure tends to rise due to a building up of compressed gas not transferred to the rear of vane C. Valves U<1> which are adjustable, release this gas when the pressure is too high, and allow part to flow through a pipe T to the induction side of the engine. Packing rings O are provided on the vanes, and packing is also attached to the abutments. The recesses P may be dispensed with and replaced by valves within the vanes which allow passage of fluid at the correct pressure. Valves U<1> may be of the ball type.

Title: Improvements in and relating to control systems for electrically-driven strip rolling mills
IPC: B21B37/54
Filed: 1935-12-13
Abstract: 454,197. Control of two motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Dec. 13, 1935, No. 34666. Convention date, Dec. 13, 1934. [Class 38 (iii)] In a strip rolling-mill having a roll driving motor 13 and a reel driving motor 14, in which the speed of the mill is adjusted by field control of the motor 13 and in which an electricallyoperated device 26 energized by the current input to the motor 14 gives indications of the tension in the strip, the device 26 is automatically calibrated in accordance with movements of the speed controlling means so that its indications are correct for all mill speeds. The motors 13, 14 are fed from a Ward-Leonard generator 15 controlled by a regulator 16 and mill speeds above the basic speed corresponding to full excitation of the generator 15 are obtained by a regulator 17 in the field circuit of the motor 13. The indicating device 26 comprises a moving coil 28 energized from a shunt 29 in the armature circuit of the motor 14, and a stationary energizing coil 27 which is adjusted by a regulator 30. The regulators 17, 16 and 30 are operated by a common handle 18, and are arranged so that when the regulator 16 has been fully operated the regulators 17, 30 are then operated together. Thus the device 26 is automatically calibrated during the controlling range of the regulator 17, and its tension indications are correct for all speeds. The armature current of the motor 14 is maintained constant by a vibratory regulator 22 energized in accordance with the armature current and controlling a field resistance 23. The regulator 22 is adjusted by varying either a resistance 25 in series with its operating coil 22d or the resistance 24 in the armature circuit of the motor 14 across which the coil 22d is connected.

Abstract: 642,448. Electric motor control systems. MOROVIAN ELECTRICAL ENGINEERING WORKS, and KLIMA, V. Dec. 31, 1947, No. 35067. Convention date, Dec. 8, 1941. [Class 38(iii)] An arrangement for phase compensation of a stator fed A.C. shunt commutator motor includes (i) an induction regulator or a regulating transformer to inject a voltage in the rotor to regulate the speed; (ii) a transformer to inject a compensating voltage in the rotor for phase compensation, and in addition another component of the compensating voltage is introduced in the rotor by feeding the induction regulator or the regulating transformer with an additional voltage displaced in phase with respect to the mains voltage. Fig. 1 shows a 3-phase stator winding 1 connected to supply lines R, S, T through reversing control relays 10, 11. A double wound induction regulator 3/4 has its primary winding 3 in series with a tertiary winding 7 of a transformer 12, the other ends of the winding 7 being connected to the lines. The primary winding 5 of the transformer 12 is fed from the lines through reversing control relays 8, 9 and connected at the other ends to resistances 13 and condensers 21 acting as phase shifters. A secondary winding 6 of the transformer 12 is connected in the rotor circuit including the secondary winding 4 of the induction regulator. Speed is regulated by a voltage applied to the rotor 2 from the winding 4 while phase compensation is produced by injecting into the rotor circuit a voltage produced by the winding 6 together with another additional voltage introduced in the rotor circuit by the tertiary winding 7 through the induction regulator 3/4. In a modification two transformers are used instead of one and in a further modification, the transformer windings may be arranged with the induction regulator itself. In a still further modification, the primary of the induction regulator is connected to a tapping in the stator winding. The commutator A.C. machine can be used either as a motor or as a generator by changing over the switches 8, 9.
