A breeder-converter nuclear reactor comprises a generally cylindrically shaped core including a plurality of removable fissile fuel plate assemblies and a plurality of removable fertile material plate assemblies, the assemblies in the central portion of the core being arranged with each fertile material assembly longitudinally surrounded by fuel plate assemblies. Each assembly comprises a number of flat plates of fissile or fertile material clad with zirconium or stainless steel and arranged in a container of square crosssection. The fissile material may be enriched uranium or thorium enriched with uranium 233, and the fertile material is thorium. Fig. 2 shows a cross-section of the core of the reactor wherein the fissile assemblies are shown crosshatched ; in the centre each fertile assembly is surrounded by fissile assemblies, and in addition there is a surrounding blanket of fertile assemblies. The central fuel elements burn up at a greater rate than the outer ones, so that when the unit is to be refuelled the depleted fuel is removed from the central part of the core, the outer fuel is transferred to the centre, and new fuel assemblies are placed at the outer side of the core. Fig. 7 illustrates the arrangements for changing the fuel elements. The reactor 10 is cooled by heavy water and is disposed at the bottom of a tank 50 which is filled with water. A fuel shielding tank 52 is joined to the top of the reactor by a fluid-tight connection to the flange 24, and the lower half of the tank 52 contains heavy water whilst the upper part is filled with a clear organic liquid which is immiscible with water, such as diphenyl, this liquid forming a radiation shield. The closure member 20 is removed from the reactor and stored in the tank 52, and fuel elements are then shifted or removed from the reactor and hung on the rack provided in the shield tank. The fuel elements can be observed visually during this operation. After refuelling the closure member 20 is replaced and the contents of the tank 52 replaced by water ; the heavy water and the diphenyl removed from the tank 52 may be separated by known methods.

Title: Improvements in or relating to gas turbine plants
IPC: F02C1/08
Filed: 1945-10-30
Abstract: 604,155. Gas turbines. SULZER FRERES SOC. ANON. Oct. 30, 1945, No. 28776. Convention date, May 5. [Class 110 (iii)] In a gas turbine plant of the type in which the turbine driving the compressor is driven by working medium flowing in a circuit and a useful output turbine is driven by working medium taken off from the circuit, the exhaust gases from the useful output turbine pass through a heat exchanger at normal loads but. at higher loads pass through an exhaust gas turbine installed after the useful output turbine. The heat exchanger may be used to pre-heat the air for a combustion chamber in the plant and the exhaust gas turbine may be used to drive a compressor supplying make-up air to the circuit. The air from the compressor 1 is divided into two parts, one part flows through a heat exchanger 5 and a tube system 9 in a conbustion chamber 10 to the turbine 12 driving the compressor and from there through the heat exchanger 5 and cooler 15 back to the compressor and .the other part flows through a heat exchanger 7 to act as combustion air in the combustion chamber 10 which supplies gas to the useful output turbine 19. The exhaust gases from the turbine 19, at normal loads, pass to the exhaust pipe 25 through the heat exchanger 7 but at higher loads are diverted by means of the valves 21 and 22 through the exhaust gas turbine 23 driving the compressor 31. The valves 27 and 28 are operated simultaneously with the valves 21 and 22 so that at normal loads the make-up air is taken from the atmosphere but at higher loads is supplied by the compressor 31.

Title: Improvements in tools for applying wire straps or ties to boxes, bales and the like
IPC: B65B13/02
Filed: 1935-10-21
Abstract: 463,274. Strapping boxes &c. POWER & SONS, Ltd., F. A., and POWER, E. A. Oct. 21, 1935, No. 28948. [Class 45] [Also in Group XV] A tool for applying wire straps or ties to boxes, bales, and the like in which the tie has at one end a deformable locking-member through which the other end is passed, and in which a jaw grips the stationary part of the tie during the tensioning and sealing, the jaw is adapted to be held in the gripping position by a member which is moved to release the jaw only after a full working-stroke of one of the levers which seal the wire tie has been completed. The invention is described as applied to a tool of the type described in Specification 231,822, [Class 45]. During the tensioning, the stationary end of the wire is gripped between a serrated surface e on the tool body and a complementary surface f on a movable jaw g. The jaw g is pivotally connected to the free end of an arm k pivoted on a fixed stud l, a torsion spring m urging the arm k upwardly. A wedge block n mounted on the end of a rod p which is slidably guided on the body has an inclined face r adapted to engage a complementary face on the arm k, and when the lever d is rocked over to commence the tensioning of the wire, a finger s on the lever engages the block n and forces it between the arm k and a surface t on the body so that the arm k is rocked and the jaw g urged to grip the wire. At the completion of this movement a surface u on the block n engages a complementary surface v on the arm k so that the jaw is held closed. A bracket x adjustably secured on the rod p carries a spring-pressed pawl y which is adapted to project into the path of a tooth z on the lever b, the tooth being so situated on the lever that after the block n and rod p have been moved by the lever d to grip the wire, and the levers a, b are operated to seal the tie, the tooth z rides over and engages with the pawl y just as the lever b reaches the end of its working stroke. On the return movement of the lever b, the tooth z engaging the pawl y moves the rod p and block n back to release the arm k and thus allow the jaw g to release the wire. By this arrangement, the jaw g cannot release the wire unless the lever b has made a full working stroke to seal the tie completely. The bracket x is adjusted on the rod p to suit the thickness of the wire of the tie being sealed.

Title: Method of and apparatus for forming group stitches
IPC: D05B47/00
Filed: 1934-10-10
Abstract: 425,017. Sewing-machines. FAIRWEATHER, W. C., 65, Chancery Lane, London.-(Singer Manufacturing Co. ; Elizabeth, New Jersey, U.S.A.) Oct. 10, 1934, No. 28980. [Class 112] Buttons, attaching; needles, vibrating laterally; thread-tensioning devices.-The invention consists in improvements in the needle-thread control of machines for producing a group of stitches such as button-sewing machines. In the example shown, the driving shaft B rotates a looper shaft C through suitable gearing including a connection C<3> for alternately accelerating and retarding the speed of the looper shaft relative to the driving shaft. The needle bar D is given its up and down move. ments by a crank arm D<5> link-connected to the needle bar and carried by an oscillatory actuating shaft D<6> actuated from the main shaft by a pitman E. The main shaft B has a worm rotating a gear secured to the shaft F carrying a cam disc FA which oscillates the lever G on the pivot G<1>. The shaft F makes one complete rotation during the formation of each group of stitches of a complete cycle. The groove in the cam F is shaped so that during all but a small final portion of each sewing operation the lever G, and thereby the lower bearing DG of the needle bar, are oscillating to-and-fro in timed relation with the oscillations of the needle bar shaft so that the needle alternatively penetrates button thread holes at opposite sides of a vertical plane. During the final portion of each stitching operation, in which the needle makes two or three final downward strokes, the oscillation of the lever G is interrupted owing to the shape of the cam groove. Consequently, the last few needle strokes penetrate the same hole and form knotting stitches. The button is held by a clamp h carried by an arm H pivoted to a sliding work-carrying member HA. It is given to-and-fro movements for four-hole. buttons by a vertical crank-shaft I. The driving shaft B is rotated by a pulley BJ loosely mounted on the shaft but normally coupled thereto by the engagement of a projection BJ<1> with an arm B<5>. The pulley BJ is moved on the shaft to shift the projection BJ<1> into and out of the path of the arm B<5> by a cam J<1> on a stop-motion shaft J. Mounted in the arm of the frame A alongside the needle bar is a rock-shaft K having arms K<1> and K<2>. The arm K<1> is connected by a chain K<3> to the button clamp arm H and the arm K<2> has a treadle connection by which the shaft K may be rotated to lift the button clamp away from the cloth plate for the insertion and removal of the goods to which the buttons are to be attached. The thread passes through an intermittent tension control L, a steady tension M and an intermittent thread clamp N. A thread pull-off arm O is attached to the rocker K. The normal take-up action of the needle bar is supplemented by the take-up S. Threads, cutting.-The thread is gripped and severed below the throat plate by a cutter P actuated by an eccentric FC on shaft F by links PF<1>, PF<2>.

[Class 130.] Filter tips for cigarettes are made by feeding strip material, the width of which is a multiple of the desired length of tip, to forming mechanism in which forming elements act transversely on a length cut from the strip to produce a substantially cylindrical filling, ejecting the filling axially and, in timed relation to the forming mechanism, subdividing the filling to obtain a number of filter tips at each operation of the forming mechanism. In one form, a length of material is severed from a strip 1 by a cutter 2<a> and is formed into a cylindrical filling 5 by rolling, folding, bunching or otherwise in a forming unit 2, from which it is ejected axially in stages by a plunger 3. Lengths 5a are out off by a rotary-disc or other cutter 4, each length being received by a spoon 6 for insertion into a cigarette paper tube or mouthpiece. In a modification, the plunger 3 ejects the fillings into a chamber in an intermittently rotating drum or other carrier, from which the fillings are ejected in stages by a second plunger. The fillings may be cut on leaving the drum, or cut while in the drum by cutters operating through slots in the drum ; or the subdivision may be effected in the forming unit, which is suitably slotted.
