Abstract: 164,850. Adams, Sir H. Goold-, and Mitchell, J. March 16, 1920 Couplings, automatic.-In automatic couplings, of the type described in Specifications 26165/04 and 16063/13, in which a revolving disc hook is locked in the coupled position by a spring-actuated transverse locking-bar, the locking-bar is provided with a wedge-shaped surface which engages under spring pressure in the locking position in a recess in the revolving disc hook and maintains the coupler heads in close engagement. In Fig. 1, the coupler heads 1, 1<1>, shown as applied to the combined buffer and draw gear described in Specification 6083/09 are shown in the locked position, the bar 7 locking the disc hook 5. The locking-bar has an offset wedgeshaped projection 10 which engages with a corresponding inclined surface 11 on the disc hook 5 and a spring 8 tends to force the inclined surfaces into deeper engagement, thereby revolving the disc hook 5 and making a tight coupling. In crder to prevent the locking bar in its coupled position from being accidentally displaced so that the recess 18 is brought opposite the disc 5, a locking-member 21 is secured to the coupler head by pins 23, and has a small projection 24 which engages a removable projection 25 on the locking- bar. When uncoupling, the member 21 is lifted by a projection 27 clear of the path of the stop 25 : the bar 7 is then pulled out until the latch 19 drops into the recess 18, as described in Specification 8751/06; the bar being retained in the uncoupling position by the latch. On parting the vehicles, the edge of the disc hook 5 passes up through the slot 18 and uncoupling is effected. In a modification for preventing any accidental displacement of the locking-bar, a pawl attached to the coupler head engages in ratchet teeth at one end of the bar 7.

Abstract: 1,010,901. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Feb. 20, 1962 [March 3, 1961], No. 7937/61. Heading G6C. A nuclear fuel element comprises a sheathing encasing the fuel and containing a heat transfer medium which is liquid at the operating temperature of the element, a gettering material having an affinity for extraneous substances in the heat transfer medium, such as oxygen and hydrogen which are potentially deleterious to the sheathing, being included in a non-structural role to contact this medium. By way of example, a fast reactor fuel element comprises annular fuel segments 11 and a breeder segment 14 housed between an inner vanadium sheath 12 and an outer niobium sheath 13, the outer sheath 13 being welded to a niobium plug 16 with a free space 17 between the breeder segment 14 and the plug 16. Screwed into the top of the plug 16 is a stainless steel end fitting 18 pierced by holes 20 giving entry for liquid sodium coolant to the inner flow channel through the element. Holes 23 permit the liquid sodium to pass from the outside of the fuel element to the free space 17 which contains the gettering material in the form of a tube 21 of zirconium or titanium. When the element is in use in a reactor, the sodium filling in space 17 remains virtually unchanged, sodium being expelled and returned through the holes 23 only to the extent induced by expansion and contraction. The invention further comprises a method of sheathed fuel element manufacture in which a liquid heat transfer medium for thermally bonding the sheathing with the fuel is brought. during introduction into the sheathing, into contact with a gettering material which has an infinity for unwanted impurities in the heat transfer medium and is incorporated in non- structural role internally of the fuel element, the fuel element being heated to a temperature favourable to the gettering of such impurities.

Abstract: 541,022. Reconditioning used oils. ROWNTREE, J. S. (Langlois, H. F., and Langlois, H. N.). May 8, 1940, No. 8286. [Class 91] Apparatus for reconditioning used oils oy treating with bleaching clay and heating under reduced pressure comprises a heating element surrounded by a conduit through which the mixture of oil and clay travels to a filter and thence to a labyrinthal chamber connected with pressure-reducing means for drawing off the volatiles. For example, mixed oil and clay is fed through a spout 15 to a container 10 and agitated by injection of air or other gas, as that discharged from a vacuum pump 24 through a pipe 29; it is drawn up a pipe 30 surrounding an electric heater 54 to a chamber 34 provided with thermostats 75, 76, one governing a valve 28 which opens, breaks the vacuum and stops the feed if the oil is too cool, and the other switching off the heater 54 at a predetermined temperature; the heated mixture is then drawn through pipes 56 and filters 66 heated by strip heaters 68. The filtered oil is taken by pipes 69, annular space 45, ports 47, annular space 46 heated by the oil in tube 30, and ports 48 to a trough 49 and baffle plates 51, 52, all roughened or covered with gauze to increase the surface area and within a chamber 35. From this chamber, volatiles are evaporated through a pipe 70 to a condenser 72 and taken by a pipe 71 to a storage tank 11 while the reconditioned oil is taken through a passage 36, an oil seal 40, and a pipe 42 to a storage tank 43. Gases in the chamber 11 are drawn through pipes 21, 23 by the vacuum pump 24 and delivered through the pipe 29 ; they escape from the tank 10 by a pipe 77. The total area of the ports 48 is greater than that of the ports 47 to prevent surging of the oil. Specification 447,139 is referred to.
