Title: Improvements in or relating to control systems for polyphase induction motors
IPC: B66C13/26
Filed: 1946-03-05
Abstract: 615,237. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd. March 5, 1946, No. 6822. Convention date, March 5, 1945. Drawings to Specification. [Class 38 (iii)] In a control system for a polyphase induction motor with a wound rotor the voltage-supply to the motor primary winding is unbalanced for low speed operation with an overhauling load and condensers are used in the motor secondary circuit in order to provide stability of speed. The unbalancing of the primary winding produces positive and negative sequence components of the motor secondary current, and, since the negative sequence current has the higher frequency, the impedance thereto is reduced by the condenser thereby increasing the braking torque component and producing a lower downward speed for a given load with a greater stability of speed over a range of torque variation. The motor secondary circuit comprises resistors, and a number of different resistor-condenser connections are shown. Reactors may be added to the secondary circuit in order to afford greater changes of torque with variations of speed and a lower downward speed for a given torque.

Title: Improvements in push-bell cable
IPC: F16C1/10
Filed: 1958-03-04
Abstract: 834,867. Bowden mechanism. AMERICAN CHAIN & CABLE CO. Inc. March 4, 1958 [March 15, 1957 (2)], No. 6919/58. Class 80 (3). The outer member or casing for a Bowden cable comprises a liner tube of thermoplastic polymeric material surrounded by a sheath of one or more helically wound round or flat wires, the plastic tube being securely engaged by the wire sheath at one or more places along its length. In the Fig. 1 construction the sheath comprises a number of long-pitch wires 12 tightly wound on a plastic tube 11 to grip it throughout its length. The wires 12 may be preformed to a helical shape or may, as shown, be surrounded by a binder wire 13 held at each end by a winding of strip 14 which is grooved to receive the wire 13. In a modification the wires 12 are wound in a separate sheath and the tube 11 is inserted therein, the strips 14 being then compressed so that only the end portions of the tube 11 are gripped. In other constructions a plastic liner tube is inserted into a sheath comprising a flat wire wound in a short-pitch helix, the wire having a trapezoidal section with rounded corners so that adjacent turns abut with their edges overlapping. After insertion of the plastic tube the sheath is swaged to a reduced diameter to grip it along the whole or parts of its length. Alternatively, or additionally, the plastic tube may, after insertion, be located by flaring its ends or by providing end ferrules, Fig. 4 (not shown), which are compressed on to the sheath. In the Fig. 5 construction a Bowden cable 40 which may be of stainless steel extends through a plastic tube 41 inserted in a sheath comprising one or more close-coiled wires, which may also be of stainless steel. The outer surface of the tube 41 has a helical groove or grooves of approximately the same pitch as the wire sheath formed preferably along its whole length, and is located in the sheath by expanding an end portion 45 of the tube 41 so that it may be screwed into the sheath. When the cable assembly is curved and is under load the grooved plastic surface is pressed against the inside of the sheath coils and is thus held against movement therein. It is stated that the grooves on the tube surface may be circumferential instead of helical, or may be of opposite hand to those of the sheath. The plastic liner tube in all constructions is preferably of superpolyamide resin or of polytetrafluorethylene, particularly where large forces are being transmitted. For small forces, however, other plastics may be used, mention being made of polyethylene, irradiated polyethylene, mixed poly - chloro - fluoro - carbons, vinyl and vinylidene polymers, and cellulosic or methacrylate compositions.
