Title: Improvements in or relating to commutators of dynamo-electric machines
Inventor: VICKERY ERNEST HERBERT WARD
IPC: H01R39/32
Filed: 1956-06-14
Abstract: 812,712. Making commutators of dynamoelectric machines. WATLIFF CO. Ltd. June 4, 1957 [June 14, 1956], No. 18465/56. Class 83 (2). A commutator brush contact member has at least one separate extension connected thereto before the said contact member is permanently secured in the commutator, the dimensions of the extension being such that, after the said contact member has been permanently secured and the finished commutator .has been assembled with the rotor, the heat applied to the free end of the extension during the process of soldering or welding it to the end of a rotor winding is not transmitted to the said member in sufficient quantity to impair the stability or insulation of the commutator. A commutator 11 comprises metal contact segments 12 embedded in an annular insulating block 13 fitted on a control bush 15, the segments 12 being separated from each other by insulators 14. Each segment 12 is formed with a slot 16 into which is soldered, brazed or welded a short length, ¢ to 6 inches, of circular or rectangular-sectioned wire 17. More than one wire may be provided for each segment 12. The wires 17 may be connected to the segments 12 while the latter are still connected in the form of a continuous length of bar stock, or in the form of an annulus, which is subsequently to be divided into the individual segments 12, or the wires 17 may be connected after the segments have been separated from one another. Again in the case of moulded commutators, the wires 17 may be secured to the segments 12 when the parts are already held in the assembly ring prior to the moulding of the insulated body. In the case of a built-up commutator the wires 17 may be secured after the segments 12 and intersegment insulators 14 have been assembled and while they are held in a clamping ring preparatory to the machining of the V-grooves for the end rings.

Title: Improvements in or relating to projection welding
Inventor: TRIBE THOMAS FRANCIS
IPC: B23K9/20
Filed: 1960-05-25
Abstract: 893,533. Welding by pressure. BRITISH FEDERAL WELDER & MACHINE CO. Ltd. May 25, 1960, No. 18559/60. Class 83 (4). In projection welding components to the rear surface, which is not coated with plastic, of a plastic coated sheet the welding electrode is pressed against the component, after welding has been performed, for such time as will ensure that a substantial part of the welding heat is conducted away through the electrode, the electrode being withdrawn from the component before the plastic coating is softened to any marked extent. The time of pressing after welding must be such that most of the heat is conducted away by the copper alloy electrode to avoid spoiling the adhesion of the plastic coating but not such that retention of the electrode against the component, e.g. a bolt, would mark the plastic softened by heat conduced thereto. With sheet steel coated with zinc on one surface and PVC on the other, the times of pressing after welding may be 0.16- 0.4 seconds. The plastic surface may rest on a copper alloy die and the term plastic includes substances such as rubber.

Title: Nuclear fuel elements
Inventor: ELTHAM BARRY EDWARD
IPC: G21C17/10
Filed: 1963-05-13
Abstract: 992, 164. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. April 23, 1964 [May 13, 1963], No. 18853/63. Addition to 900, 347. Heading G6C. A finned flat bar nuclear fuel element has an elongate impermeable frangible body secured adjacent to the outside of its sheath and in a position of inferior heat transfer through the sheath, such that swelling of the sheath in the vicinity of the body imparts a bending moment to the body to cause it to break and release a detectable substance confined in the body. As shown in Fig. 2, a flat bar of natural uranium metal 10 is enclosed in a magnesium alloy sheath 11 having chevron fins 12, 13 separated at their inner ends by ridges 15, 16. A thin alumina tube 19, 20 containing a uranium wire 19a, 20a is placed in a longitudinal groove 17, 18 provided in each ridge 15, 16 and saddles 21, 22 are placed across the grooves 17, 18 at frequent intervals in order to prevent movement of the tubes 19, 20. Should a small leak arise in the sheath 11 so that carbon dioxide coolant reacts with the uranium 10, the rate of reaction will probably be greatest where the uranium is hottest, that is in the region of the ridges 15, 16. This reaction will cause uranium oxide to be formed which will increase the volume in the sheath causing it to bulge and apply a bending moment to the appropriate one of the tubes 19, 20. The tube will fracture and fission product gases from the uranium wire will escape into the reactor coolant to be detected by coolant sampling apparatus. In order that the ridges 15, 16 do not strengthen the sheath 11 at the very points where weakness is required, slots are made at intervals in the ridges. The fuel element is shown located in grooves 23 of a fuel element channel 24 of a graphite-moderated, carbon dioxide-cooled reactor.

Title: Improvements in or relating to track brakes for railways and the like
IPC: B61K7/04
Filed: 1935-07-04
Abstract: 459,448. Track brakes for vehicles. RAIL BRAKES, Ltd., 515, Australia House, Strand, London. July 4, 1935, No. 19176. Convention date, Aug. 31, 1934. [Class 103 (i)] In weight-operated track brakes for railway vehicles, having at least one downwardly swinging brake shoe beam, the cross-section of the beam is so shaped and disposed that the axis of smallest moment of inertia is normal to the path of movement of the beam this moment of inertia being so small as to allow deflection of the beam sufficient to apply an effective retarding force simultaneously to wheels of thickness varying within the usual limits. In Fig. 1, the brake beam S pivoted by means of a shaft H has a surface A upon which the wheels run so that the weight of the vehicle causes a surface B to be forced against the side of the wheels, the other side of which are forced against a fixed reaction beam R. In order to permit the beam to bend sufficiently for the surface B to be effectively applied simultaneously to relatively thin and thick wheels as shown in full and broken lines the axis X-X of smallest moment, of inertia of the cross-section of the beam passes through the axis of the shaft H. In Fig. 2, the beam S is carried by plates 1 connected by parallel links L1, L2 to the fixed frame 3 and in this case the axis X-X of minimum moment of inertia of the cross-section is normal to the tangent Y-Y of the path of movement of the beam. In Fig. 3, the link L2 is replaced by a roller 2 on the plate 1 which engages a surface 4 which may be arcuate to correspond with the arcuate path of the upper link or parallel to the tangent to that path or as shown inclined to that tangent. In a further arrangement the beam S is guided by the engagement of curved abutment surfaces on the plates 1 with upper and lower fixed inclined surfaces. To facilitate the entry of the wheels to the brake, the run-in end of the beam may be freed from enforced parallel movement by omitting the lower link L2, Fig. 2, or the roller 2, Fig. 3. Swinging beams may be provided on both sides of the wheels.
