Patent GB-230929-A (GB)
Title: Improvements in and connected with weighing apparatus
IPC: G01G1/40
Filed: 1923-12-21
Abstract: 230,929. Benton Scale Co., Ltd., and Benton, W. A. Dec. 21, 1923. Loose - weight apparatus. - The invention relates to the type of apparatus described in Specifications 4724/12 and 17604/14 in which a rough approximation of a load above a predetermined minimum is first obtained, and consists in providing means operated by the indicating drum to select and place in weighing position weights which counterbalance the major order of the load, the minor order of the load being balanced simultaneously by a separate resistant. The selected resistants are controlled by a series of levers whose fulcra lie in one horizontal plane and are operated by a hand-actuated lever. Upon a load 7 being placed on the platform 8, the link 9 operates the beam 12, thereby raising the weight 15 from its bearings on the lever 16. The movement of the lever 16 causes the rotation of an indicating drum 20 for the minor order of the load, e.g. up to 10 cwts. If the weight 7 exceeds 10 cwts. the beam 12 is depressed until the knife-edge 21 engages the shackle 22, thereby transmitting the major part of the load to the beam 23, the free end of which is supported by a spring resistant 25. Movement of the beam 23 causes a rotation of a second indicating drum 30 and also of a serrated disc 33 secured to the drum spindle 34. Each serration on the disc 33 represents increments of 10 cwt. of the major part of the load. A hammer 35 is carried by the spindle 34 and comes to rest over one of a series of levers 39, having their fulcra on an elliptical member 49, each of which is connected by a link 40 with a bar 41. The disc 33 is locked by a detent 32 operated by a hand-lever 31, which also depresses a plate 38 to engage the hammer 35, a pin 37 being depressed and an appropriate lever 39 being operated. Each rod 41 has a number of projections 41a which release trip-levers 42 to allow levers 43 to fall. Each lever 43 supports a weight 44 and a combination of these weights proportionate to the major part of the load indicated on the drum 30 is allowed to rest on the rod 45 depending from the beam 12. Equilibrium of the beam 12 is thus restored and the knife-edge 21 is released from the shackle 22, the minor part of the load being balanced accurately by the lever 16 and indicated on the drum 20. The handle 31 operates a rod 50 through a chain 68 to return the levers 43 and weights 44.

Abstract: 263,789. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Wood, J. D.). Dec. 29, 1925, [Convention date]. Automatic circuit-breakers; cut - out arrangements. - Tripping means for reverse current circuit-breakers 8 comprise an armature member 11 adapted to trip the latch 15 of the circuit-breaker on reversal of current flow through the current coil 12 and a latch 23 on the lower end of the armature which automatically looks the armature against tripping, on armature excess current in the forward direction. The arrangement is shown in Fig. 1 for the protection of the transformers 4, 5, 6 (supplying a load in parallel) against fault in the transformers which would produce a reverse flow of power to the faulty transformer. The current coil 12, Fig. 2, acts on a core 18 fixed to the armature whereas the potential coil 13 acts on a core 19 which has some free movement thereon. In the case of a short-circuit on the secondary side of the system, the core 18 and with it the armature 11 are attracted but, before much movement can take place, the latches 23 by engagement with the fixed projections 24 are brought into locking engagement with recesses in the core 19. Consequently the circuit-breaker is not tripped. With reversal of current flow, however, under the joint influence, of both windings the core 19 is raised quickly before the core 18 is raised, and locking is prevented. Consequently the armature is lifted to trip the circuitbreaker. In a modification, the potential winding is wound upon projections external to the core structure and a magnetic latch for the armature is pivoted to one of the projections and comes under the influence of both the current and potential windings.
