Abstract: 332,670. North, O. D., Hugh, P. G., and Scammell Lorries, Ltd. May 15, 1929. Energy - absorbing elements; disc; force-transmitting elements; compensating for wear.-A watercooled brake for motor vehicles comprises a rotary brake disc disposed between a stationary and coaxially movable hollow brake member having annular water chambers connected to a source of cooling medium. The cooling fluid may be obtained from the motor cooling system and is allowed to flow on brake application by a valve operated by the brake pedal. The brake comprises a disc 1, Fig. 2, sliding on splines on a hub 19 on the transmission shaft 2, a fixed disc 5 and disc 6 moved on brake application by means of arms 7b, 8b on shafts 7, 8. The arms 7<b>, 8b have ball ends engaging shoes which bear on oppositely inclined pads 15 on the disq 6 so as to equalise the brake pressure, by axial movement of the shafts 7, 8. In an alternative arrangement the arms 7b, 8<b> carry an axially slidable bar 26, Fig. 6, having inclined faces engaging the inclined faces on the disc 6. The shafts 7, 8, Fig. 2, are operated from the foot pedal by means of a balance yoke. The disc 1 is automatically centralised by means of a frictionally held ring 20 to which it is connected by studs 22 and a collar 23. Springs 21 on the studs are compressed when the brake is applied and the ring 20 is moved to a new position when wear takes place, and there is excessive movement of the disc 1.

Title: Improvements relating to nuclear reactors and in the operation thereof
Inventor: TAYLOR ANTHONY JAMES
IPC: G21C15/04
Filed: 1956-05-16
Abstract: 858,504. Nuclear reactors. BABCOCK & WILCOX Ltd. May 16, 1957 [May 16, 1956], No. 15202/56. Class 39(4). Coolant flows through a number of zones of a reactor so that the amount flowing through each zone can be controlled to obtain a desired outlet temperature. The coolant from a pump 2, Fig. 1, is controlled separately at 22, 25, 28 according to outlet temperatures at 31, 32, 33 so that gas flowing through fuel channels in a central zone and in two annular zones leaves the reactor core at the same temperature, before passing to a heat exchanger 5. In a further embodiment, Fig. 5, gas in controlled proportions is admitted by different pipes 76 through the wall of a pressure vessel 52 into windboxes 101 to 108 each supplying fuel channels within one of eight zones. These windboxes are formed by cylindrical partitions 91 to 97 beneath a graphite core 51 supported on a plate 56 and grid 57. The outlet from the outermost zone, supplied by windbox 108 may be at a higher temperature and superheat steam generated in a heat exchanger supplied with hot gas from the inner zones. When the fuel elements in the inner zones are partially consumed they may be exchanged for elements in outer zones. Within each zone some channels are permanently throttled to different extents so that those channels in the zone in which the fuel elements are hottest receive the maximum amount of gas in the zone. The reactor is connected to four pairs of heat exchangers, each pair with a pumping system and network of pipes 76, all four pipes for the innermost zone supplying the common windbox 101 and so on outwards. A gas seal 65 divides the upper part of the pressure vessel from the lower part. The reactor described uses natural uranium and carbon dioxide as fuel and coolant.

Abstract: 799,446. Band clips. ETABLISSEMENTS COLSON. May 16, 1856 [May 17, 1955], No 15272/56. Addition to 798,042. Class 44. A ring clip of synthetic plastic comprises a base part 2 of parallelopiped form provided with a hole 6 for securing it to a supporting surface 10 and with an elongated recess 7 which extends beneath the object to be clamped, one wall 8 of the recess having a toothed formation, and a thin blade 1 extending integrally from one end of the base 2 and having a toothed formation 5 at its free end, the blade being adapted to encircle an object 9 seated on the base and to secure it by interengagement of the toothed formations on the wall 8 of the recess and on the free end of the blade. As described, the clip is secured to the surface by a screw engaging the tapped hole 6 of the base 2. The resilient blade 1 and a shorter resilient blade 4 extend from opposite sides of the base and are bent around the object. After engagement of the toothed formations, the free end 12 of the blade may be folded back on itself or severed at 13. A further embodiment which will withstand higher tensile stresses is shown in Fig. 6, and comprises a block 2<SP>1</SP> in which an open-topped recess 7<SP>1</SP> is formed, bounded on either side by flanges 16, and having a convex toothed base 8<SP>1</SP>. The flanges 16 are concave at 17 thus forming four bearing surfaces 18 to support the object 9<SP>1</SP>. Only one resilient blade 1<SP>1</SP> is used to encircle the object, but a second one may be present as in the first embodiment. A further modification is described in which the blade 1 of Fig. 3 has the teeth 5 formed along most of its length and on the side adjacent the object. The teeth thus engage the object and provide a better grip. The end portion of the blade is folded back to enable the teeth 5 to engage the toothed wall of the recess.

Abstract: 779,306. Microtomes. SITTE, H. May 27, 1955 [June 1, 1954], No. 15333/55. Class 97(1). The specimen 6 is secured to the end of a flexible rod 1 of good thermal conductivity embedded in a block 2 of large thermal capacity, means being provided for heating the block, the end of the rod being moved in a closed path so that the specimen is moved past the cutting edge 8 once in each cycle. The rod 1 may be replaced by a tube forming part of a system by which liquid is circulated also through a passage in the block 2, to assist heat transfer, by natural convection or by a pump. The block may be heated by an electrical element in bores 15 or in a cavity in the face of the block. A thermometer may be provided or the current supply may be controlled automatically by 'a bimetallic element. Cooling water, or liquified gas may be circulated through a bore 14 to cool the block in preparation for a fresh series of cuts. In the form shown the end of the rod 1 is actuated by a hand or motor driven crank 36. The crankpin is coupled by a bearing 32 to one end of a bent rigid lever 30, 31, the other end of which is coupled by a bearing 34 to the end of the rod 1. An intermediate point of the lever is coupled by a bearing 33 to a pin 40 secured to one end of a lever 39 carried on a bearing 41. To take account of the fact that the movements of the lever system are not limited to a plane the bearings 32, 34, 41 are self aligning. Alternatively the lever 31 may be a flexible strip while the levers 30 and 39 move in a plane. The lever 39 may then also be replaced by a flexible strip rigidly secured to the lever 30 and to the framework.
