Abstract: 814,217. Controlling variable speed gearing. BRITISH THOMSON-HOUSTON CO. Ltd. Oct. 18, 1957 [Nov. 15, 1956], No. 34982/56. Class 80 (2). An induction motor is connected to its load through a variable speed gear automatically varied to maintain the motor speed constant by governor means, the governor being biased to maintain the percentage slip in the motor at a desired value as the supply frequency varies. An induction motor 1 drives a load, such as the starting gear of a gas turbine, through a variable speed gear 2, the ratio of which is controlled by a governor 4 to maintain the motor speed constant. The governor is biased by a spring S loaded by a flange 5 axially free but rotationally fixed on the governor shaft 6, the flange 5 being moved axially by differential working of a screw 7 and nut 8 mechanism in which the nut 8 is driven through gears 11 from a synchronous motor 10 connected to the supply to the motor 1. The gearing 11 is determined to provide a required percentage slip in the motor 1, the motor 10 being sensitive to any frequency change in the supply and acting through the governor to cause the slip in motor 1 to remain at a desired percentage. When the motor 1 is used as an alternator after the prime-mover 20 (Fig. 3), has started, the variable speed gear 2 is connected through a high ratio gear train 18, 19 bridged by a one-way clutch b to start the.: prime-mover, and directly through the clutch b when the direction of the torque is reversed, the gears 18, 19 being bridged by a second oneway clutch a. Under these latter conditions the screw 7 (Fig. 4) moves to the right and causes pivoted jaws 12, 13 to engage a fixed member 15 to release the flange member 5 from axial connection with the screw 7. Specification 806,947, [Group XXXV], is referred to.

Abstract: 367,447. Railway &c. vehicle axletrucks. MALEY, A. W., 4, Grosvenor Road, TAUNTON, E. M., 11, Wilton Road, both in Handsworth, Birmingham. Nov. 21, 1930, No. 35166. [Class 103 (vi).] In a tramcar or like rail vehicle of the kind in which the axles are capable of lateral displacement, e.g. by the provision of swing-link or pendulum type axle-box suspensions, lateral oscillation of the body is prevented by coupling the axles together by a suitable connection so that no relative movement between them is permitted. In the construction shown the connection between the axles 2 is made through the intermediary of the motors 1, which are partly supported on the axles, and of a rigid framework comprising inclined tie-rods 14 and a central rectangular frame 15, the outer ends of the rods 14 being rigidly connected to transverse bars 7 that assist in supporting the motors. To provide for the lateral displacement of the axles, motors, and framework the rods 7, 14 at their junction are supported by flexible means comprising bolts 12<1> and upper and lower surrounding springs 8 abutting against brackets 9 which are bolted to inclined members 11 of the truck frame 10. In a modification the central frame 15 is dispensed with, the ends of the transverse suspension bars 7 being directly connected by crossed tie-rods. In vehicles having a worm drive and in which the motors are supported entirely by the truck frame, each motor may be arranged to be displaced transversely on rollers within stirrups on the cross-beams, the two motors being connected by crossed tie-rods. In cases where no axial movement is permitted between the axles and axle-boxes tie-rods forming a rigid connection between the axle-boxes may be provided for effecting the simultaneous movement of the axles.
