Abstract: 881,522. Protective cut-out arrangements. BRENTFORD TRANSFORMERS Ltd. Jan. 29, 1959 [May 9, 1958], No. 14917/58. Class 38 (5). An overload protective device comprises a transductor T having two opposed control windings CW1, CW2, the winding CW1 being supplied with a current proportional to the current of an apparatus L under test and the winding CW2 being supplied with a current proportional to the theoretical load current, any difference between these currents causing the current in the main winding of the transductor to vary and cause the operation of a cut-out switch CO or other device. In the arrangement shown, the D.C. voltage applied to the terminals BB1 of the winding CW2 is arranged to increase in proportion to the steadily increasing test voltage applied to the apparatus L at terminals AA<SP>1</SP>, so that the current produced in the winding CW1 by a current transformer CT and a rectifier R is balanced by the current in the winding CW2 under normal circumstances. Should a shortcircuit occur in the apparatus L, the current in the winding CW1 increases and is not balanced by that in the winding CW2, with the result that the impedance of the main A.C. winding is reduced and the trip coil COT of the switch CO is energized.

IPC: D01H1/241
Filed: 1921-05-30
Abstract: 185,211. Curry, M., and Cook, A. May 30,1921. Spindle-driving apparatus.-A device for use in tying driving-bands of spinning and other banddriven machines so as to provide a regulated tension comprises a member 1 engaging the spindle bearing-member 7, a tension-regulating member 3 pivoted to the member 1 at 2 and an adjustable spring 11 for normally swinging the member 3 away from the member 1. In tying a driving-band, the band is passed each side of the wharl 21 and its ends brought round a hook 30 at the top of the member 3. The knot is partly formed and the band tightened, causing the member 3 to swing towards the spindle until, at the desired tension, a notch 34 snaps over a spring-controlled latch 32 fixed to the member 1. The knot in the band is then completed and the lower end of a lever 42 is pressed towards the member 3, whereupon the upper end' portions 44 lift the band off the hook 30 on to the wharl 21. In a modification, Fig. 9, the spring 11 is replaced by a split-ring tension-spring 47 placed over the extremities of the members 1, 3 below the pivot-bolt 4.

[Class 143.] Pendulum-weight apparatus; locking mechanism. -In an automatic weighing machine, a locking mechanism for maintaining the reading after the load is rembved or for preventing derangement of the mechanism when the machine is moved, comprises mechanically operated brake blocks operating upon plain cylindrical arcs carried by the pendulum levers and concentric with the fulcrum knife-edges, the arrangement being such that the knife-edges are retained upon their seats in the locked position. The pendulum levers a<1>, a<2> mounted on fulcrum blocks b<1> b2 are provided with circular arcs g<1>, g<2> adapted to be engaged by brake blocks j<1>, j<2> carried by levers k<1>, k<2>. The pendulum lever a<1> actuates an indicating pointer e by means of gearing c, h.

[Class 35] An alternating-current machine, particularly for use as a tachometer dynamo comprises two relatively rotatable magnetic structures, one comprising unidirectional flux-producing means such as permanent magnets 11, 12 and the other 13 at least one restricted magnetic section 15, 16 dimensioned to become substantially saturated, and a coil 17 surrounding at least a portion of one of the magnetic structures so as to be threaded by a pulsating flux the maximum value of which is determined by the crosssectional area of the restricted section. The restricted portion is of such dimensions and material that it will be saturated at the lowest value of flux expected from the magnets having regard to ageing &c. and is preferably of material such as Permalloy having high permeability and a sharp knee near the saturation point on its magnetization curve. The magnets 11, 12 are preferably of cobalt steel. With the arrangement shown, the resultant effect of leakage flux on the coil 17 is zero. The stationary generating coil is connected through a bridge arrangement of rectifiers 18 to a voltmeter 23 graduated in speed units. Resistances 24, 25 of zero or slightly negative temperature coefficient of resistance are connected as shown to correct for temperature variations, and the ohmic value of resistance 24 is several times the combined resistance of coil 17, rectifier 18 and instrument 23. In a modification, the section 16 of the generator is dispensed with and the shaft extends through a hole in a stack of laminations connecting the ends of the magnets. In a further modification of this kind, the shaft is stationary and the part 15 alone rotates. A form is described giving six flux pulsations per second comprising four magnets and two three-armed inductors.
