Title: Method of increasing the efficiency of nuclear reactors
IPC: G21C3/20
Filed: 1962-11-06
Abstract: The surface of nuclear reactor structural components e.g. fuel cans is rendered corrosion resistant and capable of operating at high temperatures, by depositing on the surface one or more elements from a fine dispersion thereof in a gaseous atmosphere by electrical gas discharge e.g. a glow discharge.  The elements specified are Si, C, Cr and Ni and are preferably atomized by cathodic disintegration, and the glow discharge intensity is maintained at a high level, e.g. 0.1 watts per cm.2, whereby the surface is heated, the deposited element diffuses into the surface, and the boundary layer on the surface assumes an ideal form of a regular crystal lattice.  The cans may be made of zirconium or alloys thereof, but steel and aluminium may also be treated.  A number of elements may be applied in succession, and a final coating of C formed from a carbon halide is preferred.  Si may also be deposited from silicon halides.  The surface may be connected as cathode for the glow discharge source, and an inert gas may also be present.  Preferably the voltage for glow discharge is pulsed, and the surface is pre-cleaned by glow discharge, the ionized gas removing thereby the same amount of material as is subsequently deposited by the coating.

In a process for the production of hollow bottle-like thermoplastic articles of regulated wall thickness, a tube of plastic material of varying wall thickness extruded from an extrusion press at a constant linear speed is located in a two-part blowing mould 23 mounted below the extrusion nozzle 12. The tube is cut off by the sharp edges of the mould parts 23, Fig. 9, or by a separate cutter and compressed air is introduced into the tube through the blowing nozzle 24 to form the article in the closed mould. The extrusion press comprises a worm 3 positioned in a heated plasticizing cylinder 2, to which granulated plastic material is supplied from a hopper, and the worm 3 is mounted so that it can be reciprocated axially together with its drive 7 by the hydraulically actuated piston and cylinder assemblies 9, 10 to act as an extrusion piston. During the downward movement of the worm 3 the ring 11 at its tip acts as a non-return valve to prevent material flowing back past the worm. The plastic material is fed to a distribution head 4 from which four nozzle heads 5 offset at 90 degrees are fed through channels 6. The nozzle heads 5 have exchangeable outer nozzle sleeve members 12 in which an axially reciprocating nozzle mandrel 15 is concentrically positioned. The outlet cross-section of the nozzle is controlled by the axial movement of the mandrel 15 actuated by the piston and cylinder assembly 20, 21 between positions controlled by stop nuts 18 and a magnetic lock 19. The tube of the required varying crosssection is produced at a constant linear speed by simultaneous variation of the speed of axial downward movement of the worm 3 with the axial movements of the nozzle mandrel 15 by means of a programme controlled hydraulic circuit including the electrically or magnetically operated throttle valves 38, 39, 45 and reversing valves 35, 42. The nozzle member 12 may be replaced by a flexible sleeve 50, Fig. 11, the outlet cross-section being controlled by an axially displaceable ring 51 actuated hydraulically as previously for the movable mandrel, or member 12 may be replaced by a mechanically operated diaphragm similar to an iris diaphragm.

Abstract: 1,068,198. Brake transmitting mechanisms. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Sept. 28, 1965 [Oct. 27, 1964], No. 43733/64. Heading F2E. A load-dependent braking apparatus for a railway vehicle 1 is provided with a variable load mechanism 6, including a block 35 in which is pivotally mounted a first fulcrum 36 and a vertically slidable second fulcrum 40, and includes two bell-crank levers 13, the position of each one of which is dependent upon the load on a respective axle through linkages including weighing mechanisms 10, bell-crank levers 11 and push-rods 12, a roller member 14 which is urged by a spring mechanism (not shown) in a direction tending to engage both bell-crank levers 13 but which for any given load at the location engages only the bell crank lever associated with the most lightly-loaded location such that the position of the roller member 14 is dependent upon the loading at the most lightly-loaded location the position of the roller member 14 to alter the position of the second fulcrum 40 thus determining the degree of braking effort exerted by the apparatus. The variable load mechanism 6 includes the block 35 in which is pivotably mounted, the first fulcrum 36 resiliently urged into its position indicated in Fig. 2 by a spring 37 acting on the fulcrum through a plunger 38. Vertically slidable within the block 35 is the second fulcrum 40 connected by a linkage 41 to a rod 33 by which angular movement of the rod 33 determined by the position of the roller member 14 is tranlated into linear sliding movement of the fulcrum 40. A lever member 17 is pivoted to crosshead members 8, 9 which are coupled to the upper and lower rods 5 respectively shown entering the variable load mechanism 6 in Fig. 1. In operation, upon the commencement of the braking operation, a brake cylinder 4 will cause the crosshead 8 to be moved to the right and as the force exerted by the spring 37 is of suffi-. ciently large magnitude as not to be overcome by the force exerted against it by the lever 7 during movement of brake blocks 3 into engagement with the wheels 2 of the rail vehicle, the lever 7 will be pivoted in an anti-clockwise direction about the first fulcrum 36 so as to move the crosshead 9 to the left. This movement will continue until the brake blocks 3 engage the wheels 2 at which instant the lever 7 will be substantially vertical. After the brake blocks have engaged the wheels 2 continued operation of the brake cylinder 4 will cause the force in the brake rigging to increase to overcome the force exerted by the spring 37 so that the lever 7 will then move into engagement with the second fulcrum 40, the position of which will have been determined by the loading of the vehicle 1. The force transmitted to the brake blocks 3 will then be proportional to the loading of the vehicle at the most lightly loaded end. The invention may be applied to an empty/load braking apparatus by ensuring that the second fulcrum has merely two extreme positions rather than being adjusted throughout the whole length of its movement.
