Title: Improvements in or relating to the protection of direct current dynamo-electric machines
IPC: H02H7/08
Filed: 1924-05-02
Abstract: 234,259. Electrical Improvements, Ltd., and Porter, G. L. May 2, 1924. Cut-out arrangements.-D.C. dynamo-electric machines, for example, motors, generators and converters, are protected from the results of a fault to earth in the windings by making use of the alternating or pulsating voltage between any armature conductor and earth to energize a current transformer the secondary winding of which operates the tripping gear or operates indicating devices. In the case of a motor or generator A, Fig. 1, both the incoming or outgoing leads C, B are taken through a ring transformer D and one of the leads, for example B, is earthed on the side of the transformer remote from the machine. Sudden fluctuations of the direct current in the leads C, B neutralize one another in their action on the transformer whereas, in the event of an earth in the armature winding, an alternating current flows in the lead B and energizes the transformer. In the case of a rotary converter L, P, Fig. 2, the supply leads H, K to the motor are passed through the transformer together with a lead Q from the neutral point of the alternating current winding which, after passing through the transformer, is connected to earth on the side remote from the machine.

The A, B and C scales on each rule are calibrated in odds, with the B scale reversed, while the D scale is calibrated logarithmically in money. In the win rule the odds scales are calibrated so that the distance from the origin of an odds n = log(n + 1) and are so related that when evens on the A scale is against evens on the B scale, 0 on the C scale is against 4/- on the D scale. On the win and place rule the odds scales are given by n = log(5n/8 + 1) and on the place rule by n = log(n/8 + ¢). The scales on the win rule having been fixed the scales on the other rules are determined as is explained in the Specification.

[Also in Division G4] Nuclear reactor fuel elements, of the type comprising an assembly of plate fuel members role-clad in non-fissile material, are made by securing the plates to supports and/or to one another by electron beam welding unexposed joint faces. The plates may comprise a plate of uranium-aluminium alloy (uranium 90% enriched in V235) between two layers of aluminium. Various joints are described:- In Fig. 2, fuel plates 1 are welded into channels 5 in supports 2 (weld zone designated 7); in a modification the channels are omitted and a single T-joint formed to attach each plate edge to the supports. Fig. 4 illustrates one of a number of similar joints; as indicated, sub-assemblies are made by welds 14, which are then assembled by welds 15. Instead of the rectangular grooves shown in Fig. 4, a sawtooth profile may be used, with the plates resting on the horizontal " tooth flanks " (Figs. 5 to 7) which results in a smaller depth of solid material to be penetrated for a given number of fuel plates. Also, these embodiments show individually made weld seams for each plate edge, made at an oblique angle to the support. Fig. 8 shows an embodiment which dispenses with the supports by using shallow channel action plates; Fig. 9 (not shown) shows a modification of Fig. 8 in which plane fuel plates are used in conjunction with rectangular bar spacers between adjacent plates. Three further embodiments illustrate similar joints to those described, for building up fuel elements in the form of concentric rings, each formed by a plurality of arcuate plates welded to radial webs.
