Title: Improvements in electric indicating devices applicable to gate end boxes and the like for use in mines
IPC: B66B19/06
Filed: 1943-07-24
Abstract: 569,021. Protective cut-out arrangements ; indicators for switches. VICTOR PRODUCTS (WALLSEND), Ltd., [formerly CROFTON & CO. (ENGINEERS), Ltd., C.], and MANN, R. W. July 24, 1943, No. 12076. [Class 38 (v)] In a leakage-indicating arrangement for gate end boxes in mines, a lamp is arranged to emit a beam under all working conditions and to go out on leakage occurring or the main isolator being opened, and is associated with a press button employed for resetting overload contactors and the leakage relay. The lamp d is placed behind a red glass rod c let into the push button a in the front x of the gate-end box, and is placed in series with normally closed contacts of the leakage relay n across a transformer, the primary of which is energized by the main circuit controlled by an isolator y, Fig. 4 (not shown). The lamp thus indicates the condition of the isolator and transformer fuses, in addition to showing that the leakage relay has operated, the latter operation causing a lever o to assume the dotted position shown in Fig. 2. Each of these contactors 4 ... 6 has a push button m which assumes the position m<1>, Fig. 2, when the contactor trips on overload. In order to reset the push buttons m, an insulating bar k, guided on pins l, is adapted to be pushed backwards against spring-action by means of an arm f on the inner end of push button a when the latter is depressed. A further arm g on the end of button a carries a projection q, Fig. 2, adapted to engage and reset the lever o, for which purpose the button a is depressed and then rotated anti-clockwise, Fig. 1, by means of a special key fitting over, and engaging a notch p in, the button. A third arm h on the button normally works in a slot t between two projections r, s on the front x and is urged by spring u against projection r. When the button a is rotated after depression, the arm h being clear of the gap t moves along the back of projection s against the enlarged end s<1> thereof. When released, the button is first rotated by spring u and then restored by spring b. The leakage relay coil is in a circuit connecting the neutral wire of the 3-phase supply to earth, so as to be energized only when unbalance current flows in the neutral.

Abstract: 1,092,652. Mechanical switches. FULLER ELECTRIC Ltd. March 24, 1965 [March 23, 1964], No. 12178/64. Heading H2B. [Also in Division F2] A tap selector for a transformer comprises two selector arms on two shafts 20, 21 each co-operating with a fixed circle of contacts so that whilst one arm remains on one contact the other arm moves to the next adjacent contact. The mechanism for driving the two shafts 20, 21 from a shaft 1 comprises an arm 5 keyed to shaft 1 and carrying two pinions 6, 7 engaging a fixed gear 4, the shafts 8, 9 of pinions 6, 7 carrying arms 10, 11 having rollers 12, 13 in slots 16, 17 in arms 18, 19 keyed to shafts 20, 21 respectively. The pitch circle diameter of gear 4 is five times that of pinions 6, 7 so that as shaft 1 is rotated the axes of rollers 12, 13 trace out a five-looped hypotrochoidal path 23, Fig. 1, not shown, having its centre on the axis of shaft 1. At each loop of path 23 the angular velocity of each roller about the axis of shaft 1 is virtually zero whilst the other roller is traversing part of the path between two loops and so rotating one shaft 20 or 21 whilst the other is virtually stationary. The rollers 12, 13 may be a loose fit in slots 16, 17 to prevent slight oscillation of the shafts at each loop. By changing the ratio of the pitch circles the numbers of loops in the path can be altered but there must be more than three. For even number of loops the rollers are not diametrically opposed. In Fig. 3 (not shown) the pinions 6, 7 engaged an externally toothed, fixed gear and the path may have 1-3 loops. The number of loops in the paths may be altered by providing a step-up or step-down gear between shafts 8, 9 and arms 10, 11. In Figs. 4, 5 (not shown) a square plate is eccentrically mounted on shaft 1 and has rollers at each corner running in a fixed hypotrochoidal aperture, the two rollers 12, 13 are mounted at diagonally opposite corners of the plate to drive shafts 20, 21 as before.

Abstract: 423,356. Timing of ignition and fuelinjection pumps. BOHLI, J., 15, Dammstrasse, Solothurn, Switzerland. April 28, 1933, No. 12385. Convention date, April 29, 1932. [Class 7 (iv)] [See also Group XXVIII] The time of ignition or of fuel-injection is regulated by the action on a spring loaded piston of the pressure of an engine driven lubricating oi or liquid fuel pump Movement of the pis ton is opposed by a light spring x during idling, and at heavie: loads by a stronger spring x<1> when the clearance h<111> between the inner and outer piston members y, z, has been taken up. At higher engine speeds the fluid pressure is reduced by the opening of additional return passages f or by an adjustable throttle valve in the passage f. According to the Specification as open to inspection under Sect. 91, the delivery side of the pump may be connected to a bellows variation in the volume of which adjusts the magneto armature or the time of fuel injection. In the latter case the passage divides beyond a narrow orifice so that a sudden increase in delivery by the injection pump withdraws fuel from a bellows and retards the time of injection. This subject-matter does not appear in the Specification as accepted.
