Abstract: 607,080. Transmitting mechanical power. VAUGHAN CRANE CO., Ltd., and SADLER, G. V. Jan. 25, 1946, Nos. 2472 and 7429. [Class 38 (iv)] An electric motor 1 drives the hoisting drum of a crane or the like through an eddy current coupling 2, 3, the excitation of which is controlled, to vary the lifting speed, by a rheostat or other " stepless " regulator 11a operated by a hand wheel 12 in which is' incorporated a switch 11 having contacts which are maintained closed, in any position of the regulator, only by the application of pressure by the operator. Release of pressure de-energizes a contactor 9, thereby also de-energizing both the coupling and a release coil 13 for a brake on the drum. As shown, the coupling is energized from a potentiometer 14 connected across the brake release coil. A switch 10 controls the motor contactor 8. In the case of an A.C. motor, direct current for energizing the coupling may be obtained by rectifiers of which may be constituted by the coil 13. Other arrangements are described wherein two further stepless regulators and eddy current couplings are associated with the motor to operate cross-traversing mechanism, and wherein a second motor and two more couplings and regulators provide for longitudinal travelling of the crane. Another coupling and regulator may be associated with the first motor to provide a positive lowering torque for a light load, or this coupling may be energized simultaneously with the hoisting coupling to permit the hoisting or lowering of light loads at creeping speeds. Electrical interlocks may be provided to prevent energization of the couplings prior to starting of the motors. Overwinding and over-speed protection may also be provided. Specification 540,346, [Group XXXVII], is referred'to.

Title: Hydraulic turbo transmitters with adjustable guide vanes
IPC: F16H61/56
Filed: 1937-01-29
Abstract: 485,125. Hydraulic transmission of power. VOITH, W., VOITH, H., and VOITH, H., (trading as VOITH, J. M., [Firm of]). Jan. 29, 1937, No. 2735. Convention date, Feb. 10, 1936. [Class 69 (ii)] In a hydraulic torque converter of the Fottinger type having a stationary reaction member between the runner outlet and impeller inlet, the individual guide vanes of the reaction member are associated with a common control member whereby they can be adjusted. The inlet ends only, or the outlet ends only, may be adjustable ; the inlet and outlet ends may be independently adjustable ; the vanes may be adjustable as a whole whereby inlet and outlet ends are simultaneously adjustable. Where only part of a guide vane is adjustable, the vane may be made of resilient material, the adjustable part being capable of deformation while the remainder is rigidly fixed to the reaction member. Adjustment is in some cases effected at will by a hand or foot lever, and in other cases is effected automatically as, e.g. in accordance with secondary speed, or with ratio of primary to secondary speeds, or with primary or secondary torque, or with the difference or the ratio of said torques. In one form, Fig. 1, the guide vanes f are pivotally mounted in the fixed casing e, levers g fixed on the vane spindles being pivotally connected to a common rotatable ring ; the vanes are rectangular in elevation, so that the outlet flow area is less than the inlet flow area for all settings of the vanes, whereby the liquid is accelerated from reactionmember inlet to outlet. In a modification, Fig. 7, the vanes f are pivoted at h<1> on a stationary ring h and are connected by pins i<2> and slots f<1> with a ring i rotatable against the restraint of a spring K, its rotation being limited by a projection i<1> and stops l<1>, l<2> ; the vanes set themselves automatically in accordance with the difference of primary and secondary torques and thus indirectly in accordance with the ratio of secondary to primary speeds. The invention is applicable to road vehicles, and the effect of the various adjustments is discussed in some detail together with the theoretical considerations.

IPC: B60Q1/34
Filed: 1927-11-01
Abstract: 305,549. Telford, A. E., and Hyde, A. Nov. 1, 1927. Road-traffic signals on vehicles.- A direction-indicating arrow is given a flickering appearance when a hand-switch is closed, by reason of a shutter which is eleetromagnetically caused to vibrate. Further, when the foot or hand brake is actuated the red tail light is changed to show an illuminated stencil "stop." Each signal arm 3, 4 has an arrowshaped opening 7, 8 formed by transparent windows behind each of which is a stationary plate 9 having vertical slots 10. Behind the plate 9 is a slidable plate 11 carrying an armature 16 aud having vertical strips of the same colour as the intervals between the slots 10. Between these strips are louvres 12, the front faces of which are silvered. Normally the parts are as shown in Fig. 2, but when the driver closes a switch to R or L, Fig. 4, a magnet 15 or 15a is energized to operate the appmpriate plate 11 against its spring 17. As the circuit includes an interrupter 18 of known form, the plate 11 vibrates and gives the arrow a flickering appearance. Between the arms 3, 4 is a housing 5 having a lamp 19 adapted to shine through an opening 20 on each side on to the arrows 7, 8 and to shine through a lower operation 21 on to the number plate of the car. A stationary member 13 and a movable member 14 behind it are. of such grid-like, formation that in their normal positions they provide a red circle for the lamp to shine through; this gives the tail light; but when 14 is moved this circle disappears and the stencilled work " Stop " takes its place. The member 14 is moved by the armature lever 23 of a magnet 22 operated from the brake contacts 24. The lamp 19 is also in this circuit, but may also be constantly alight at night.
