Title: Improvements in or relating to rotary electric transformers for coupling two alternating current networks
IPC: H02K47/20
Filed: 1926-01-08
Abstract: 246,133. Siemens - Schuckertwerke Ges. Jan. 17, 1925, [Convention date]. Equalizing load in systems depending on two or more machines.-For coupling two alternating-current circuits of fluctuating or different frequencies and effecting an interchange of power between them, a converter is employed consisting of two machines of asynchronous type provided with a flywheel mass and with regulating devices for altering the loadspeed characteristics of the machines. The set has the property of changing its speed without affecting the two circuit frequencies, and may consist cf two asynchronous machines cascaded with commutator machines, in which case regulation is effected by controlling the secondary voltage which is introduced into the slip circuit by the commutator machine. Alternatively, two three-phase shunt commutator motors may be employed with regulation by brush-shifting. Fig. 1 shows a form in which the circuits 1, 2 are connected by a converter comprising, two 3-phase shunt machines 3, 4 with a flywheel 5 on their common shaft. By regulating one machine as a motor subsynchronously and the other as a generator hypersynchronously, power may be transferred from one circuit to the other. With a sudden power demand, on the circuit 2, for instance, the machine is regulated to act as a generator, putting a greater load on the converter shaft and bringing, the flywheel into action to give a buffering action. Tirrill or other quickaction regulators may be used to regutate the machines automatically and bring about the buffering action at prescribed load conditions. When the generator element does not work in parallel with other machines, it may be regulated in accordance with the frequency, voltage, or other condition of the. supply or consumption circuit by means of a frequency relay or other device; when it works in parallel with other sources, it may be automatically regulated in accordance with the whole or a part of the load current.

Title: Improvements in hydrostatic transmission systems
Inventor: MACDONALD JOHN GRAHAM
IPC: F16H47/04
Filed: 1964-01-07
Abstract: 1,098,191. Variable-ratio gears. DOMINION ROAD MACHINERY CO. Ltd. Jan. 5, 1965 [Jan. 7, 1964; Jan. 27, 1964; March 23, 1964], Nos. 713/64, 3386/64 and 12188/64. Heading F2D. A planetary gear has a sun 27 geared to an input shaft 1, a planet carrier 29 fast with an output shaft 33, and a ring gear 25 connected to the input shaft by way of a hydrostatic transmission comprising a variable displacement primary pump 3 and a constant displacement secondary pump 7 which is connected to the ring gear 25 by a two-speed constant-mesh gear 38 which provides a first ratio when the ring gear 25 drives the secondary pump 7 in the direction R in order to give zero or low speeds to the output shaft 33. This ratio is such that the secondary pump 7 is rotated faster than the ring gear, with a consequent reduction in torque so that this pump can be smaller than would otherwise have been possible. The gear 38 provides direct drive or a second ratio when the secondary pump 7 rotates in the forward direction F, and drives the ring gear to give high speeds to the output shaft 33. As shown the gear 38 has gears 9, 18 meshing gears 11, 17, gear 17 being fast with a countershaft 16 and gear 11 being connected to the counter-shaft by a ratchet clutch 10 of the jamming roller type which engages when the ring gear 25 is rotated in the direction R and acts as the driving member. The gears 9, 18 are directly connected by a jamming roller type ratchet clutch 19 when the secondary pump 7 rotates in the direction F and acts as the driving member. In operation, on starting, the pump 3 is set to rotate the secondary pump 7 in reverse at a speed corresponding to the output shaft 33 being stationary; reduction of the pump displacement and then reversal and increase up to its positive maximum displacement increases the output shaft speed up to its maximum in a forward direction. While the pump displacement is being reduced from its initial displacement to zero the clutch 10 is engaged so that the secondary pump 7 rotates more rapidly than the ring gear; from zero to maximum displacement of the pump the secondary pump is driven in a forward direction so that the clutch 19 locks up and the ring gear is driven at the speed of the secondary pump 7. In modifications the two-ratio gear 38 provides a step-down ratio when the secondary pump 7 is driven in reverse by the ring gear and a step-up or a step-down ratio when the pump 7 drives the ring gear forwardly, the gear again being of the constant-mesh type with the ratios introduced by jamming roller ratchet clutches. As shown the variable ratio gear is used to drive a winch drum 34. When used to drive a vehicle the output shaft may be followed by a reversing gear having two gears fast on the output shaft 33, one meshing a gear loose on the final driven shaft and the other meshing a second loose gear through a reverse idler, the loose gears being clutchable to the driven shaft by a double dog clutch.
