Title: Nuclear Fuel Assembly
IPC: G21C3/322
Filed: 1968-08-27
Abstract: 1,169,868. Fuel elements. SOC. BELGE POUR L'INDUSTRIE NUCLEAIRE S.A. BELGONUCLEAIRE. 27 Aug., 1968 [7 Sept., 1967], No. 40829/68. Heading G6C. In a fuel element assembly, the fuel elements are subdivided longitudinally into several bundles between which flow-twisters are placed, which flow-twisters force the coolant from one region within one bundle into another region with a different power generation within the next bundle. A more uniform coolant outlet temperature is thus obtained. In one particular example, a radial blanket fuel assembly for a sodium cooled fast reactor comprises two bundles 11, 12 of fertile rods 13 located within a hexagonal wrapper 14 in a triangular lattice and supported by upper and lower grids 15, 16. A flow-twister 17 is integral with the upper grid 15 of bundle 11 and the lower grid 16 of bundle 12. Sodium coolant flow is shown by arrows 20. The flow-twister may be helical with either two or three blades, or may be a device with cross flow ducts where half the flow goes through a central passage and the other half is led in cross flow round this passage. The fuel elements may be in the form of rods, plates or otherwise shaped elements.

Title: Regulation of the fuel supply of a gas turbine
IPC: F02C9/32
Filed: 1958-12-18
Abstract: 909,832. Gas turbines; jet propulsion. SCHMIDT, F. A. F. Dec. 18, 3958 [Dec. 19, 1957], No. 40916/58. Class 110 (3). The fuel supply of a gas turbine engine comprises a distributer having a number of fuel inlet ports spaced apart on the circumference of a circle, a number of fuel outlet ports spaced apart on the circumference of a circle in a surface which faces the inlet ports, and two rotating discs which have apertures therein which co-operate with each other to permit the flow of fuel from the said inlet to the said outlet ports, the discs being also rotatable by a governor relative to each other to vary the overlap of the apertures and vary the fuel supply according to the speed of the engine, additional means being provided to vary the fuel supply in response to engine operating conditions such as atmospheric temperature and pressure, altitude and engine load. The pressure of the fuel supplied from the pump 1 to the distributer 2 is varied by a bleedoff through bores 7 and 9, the rate of bleed being controlled by the compression of a spring 10 acting on the piston 8. This compression is varied by the movement of a lever 15 which compounds an input from a cam 11, operated by the engine load selection lever, and an input, proportional to envoironmental air pressure and temperature, provided by a pressure box 13. In one embodiment of the bleed-off device (Fig. 8, not shown), the lever is also affected by changes in the exhaust gas temperature. Part of the bled fuel is fed to the ignition burners 17, the flow being controlled by a further bleed-off device adjustable by a cam 18 which is regulated to keep the mixture proportion for the ignition burners substantially the same for every operating condition. It is stated that cam-plate 18 may be set by a servo system controlled by a Venturi device which measures the weight rate of flow of air through the ignition combustion chamber. Alternatively, the setting may be regulated according to the atmospheric conditions and the engine speed. The engine load selection lever is also coupled to an hydraulic system 22, which displaces the bullet 28, and to a camming ramp on the distributer, described in Specification 868,074, which reduces the flow of fuel when conditions approach the surge limit of the compressor. The distributer (see Figs. 9 and 10) comprise apertured discs 52, 53 rotated, with the governor weights 54, by the engine. The weights are joined together by pins 69 each pin engaging one forked end of a lever 70 pivoted on the shaft 61. A link 57 pivoted at 56 to one weight and at 58 to a member 60 attached to the shaft 61 effects relative movement between the discs 52, 53 as the engine speed increases and the weights move outwards. The position of the pivot 58 on the member 60 is varied by one end of a lever pivoted to the disc at 63, the other end of the lever being engaged by the rod of a spring-loaded piston 64 subjected at its underside to fuel pressure.

Title: Improvements in or relating to punching apparatus
Filed: 1958-12-18
Abstract: 842,440. Selective punching apparatus. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Dec. 18, 1958, No. 40959/58. Class 31 (2). Punching apparatus comprises a plurality of independently lengthwise movable punches arranged for co-operation with a die and normally retained in spaced relation with the die by retaining means individual to the punches and selectively operable to effect release of the punches, the punches on release thereof being movable with and relative to a carrier reciprocable relative to the die and to the punches in their retained positions so that the released punches effect punching due to the kinetic energy thereof and are then restored by the carrier to co-operation with the retaining means. As shown, the punching apparatus comprises punches 15 supported by a carrier 8 reciprocable towards and away from a die 1, the punches being normally retained in spaced relation with the die by energized stationary electromagnets 26 co-operating with armatures 19 fitted at the ends of the punches, and during movement of the carrier towards the die the electromagnets are selectively de-energized to release the punches which are then movable with and relative to the carrier by means of compression springs 20 surrounding the punches, at a speed such that punching is effected by the kinetic energy of the punches. When the carrier moves away from the die it takes with it the selected punches and presents them to the corresponding electromagnets which by this time have again been energized to retain the punches spaced from the die. Each spring is compressible by the carrier during movement thereof towards the die when the punch is in its normally retained position and is so constructed that the load of the spring when compressed by the carrier is less than the magnetic force by which the punch is held in its retained position. The apparatus is similar to that described in copending Specification 842,439.

Title: Method of making flanged wheels
Inventor: BROOKS DEWEY HOBSON
IPC: B21D53/26
Filed: 1963-10-28
Abstract: 986,787. Making sheet metal wheels; stamping; trimming-dies; bending. SHEFFIELD CORPORATION. Oct. 28, 1963, No. 42458/63. Headings B3A, B3E, B3Q and B3W. A method of making a sheetmetal pulley &c. wheel, Fig. 11, comprises drawing a blank into cup shape having a central disc 10, Fig. 1, and a cylindrical flange 18 with an offset 20 and a flared portion 19, sliding the offset portion 20 relatively to a camming punch 25, Fig. 2, to bulge or bend the flange while maintaining the flange-diameter adjacent the flared portion 19, and axially compressing the blank to overlap the bulged portion of the flange upon itself, forming one side of the wheelrim the other side of which is formed by the flared portion 19. The drawing tools, Fig. 1, include a stationary punch 11, a stripper 14, a work-holding ring 12 supported by pins 15 on a pressure cushion, and a drawing ring 13. During the operation of bulging the flange, the disc is located in an upper workholder 30 while the flared portion 19 is held in a recess 27 in a lower workholder 26 by radially movable elements 28. The workholders and elements 28 are moved downwardly, carrying the offset portion 20 of the flange into engagement with the camming section, Figs. 3 and 6 (not shown), of the punch 25, and then continuing until the disc 10 engages the end of the punch, Fig. 2. Pins 27<SP>1</SP> operated by a pressure cushion support the workholder 26. The flared portion 19 may then be trimmed by a punch-and-die set 37, 39, Fig. 4, having a workholder 43 and springs 41 between the workholder and a die-carrier 42. Overlapping the bulged flange is effected in several operations, in the first the flared portion 19 is clamped by radially movable members 49, Fig. 5, to a raised workholder 47 movement of which is restricted by a stop 48. A punch 45 supports the underside of the disc while a die 50 engaging the top side, is moved downwardly causing the flange to buckle outwardly. The workholders 47, 49 are moved downwardly by a ring 51 on the die 50. The flange adjacent its connection to the disc, is straightened in section by a stationary punch 56, Fig. 8, and a die 60, the work being held against a workholder 57 by radially movable members 58. Closing of the flange to form the upper wheel-rim follows, the blank being held between a punch 64, Fig. 9, and a downwardlymovable die 71 by a work-holding ring 67 and radially movable clamping dies 70. Finally, the periphery of the flared portion 19 is turned down and a hub-hole is punched in the disc by coaxially arranged cutting out and shaping dies, Fig. 10 (not shown); the wheel may then be welded to the hub 75.

Title: Improvements in or relating to inflatable acceleration-protection garments and pressure controlling valves therefor
IPC: F16K17/00
Filed: 1959-12-14
Abstract: 890,623. Fluid-pressure servomotor control systems. BENDIX CORPORATION. Dec. 14, 1959 [Dec. 29, 1958], No. 42471/59. Class 135. [Also in Group XXI] The inflation of a pressurized acceleration protection garment worn, e.g., by airmen, is controlled by a valve device comprising a main valve 32 controlling the supply of inflating fluid from an inlet 12 to an outlet 24 to the garment (not shown) and controlled by a pilot valve 50 actuated by displacement of an accelerometric mass 78, there being means for applying a regulating pressure to modify the response of the pilot valve to the accelerometric mass. Fluid from the inlet is supplied to the upper side of a diaphragm 22 of the main valve through a restriction 18 and the pressure on this diaphragm is controlled by a hinged pilot valve 50 controlling a leak-off into a chamber 44 which communicates with the outlet 24, the pilot valve being actuated by the mass 78 through a beam 82 which acts on a stem 88. This stem is carried on a diaphragm 42 responsive on one side to the pressure in chamber 44 and on the other side to ambient pressure or a control pressure regulated e.g. as a function of altitude, at 34. Downward movement of the mass 78 on acceleration causes opening of the main valve 32 and is also arranged through the beam 82 to hold closed a vent valve 66 controlling a vent opening from a chamber 70 connected to the outlet 24 and to chamber 44. On removal of the acceleration force, the beam 82 rises to open the vent valve 66 and deflate the garment. This vent valve is carried on a diaphragm 68 and is exposed at 36 to ambient pressure or a control pressure also regulated according to altitude. A spring-loaded relief valve 100 prevents over-pressurizing of the garment. The beam 82 may also be depressed by a manual push-button 94 acting through a spring against the weight 78, so as to operate the main valve for test purposes.

Abstract: 1400115 Releasable fastenings J LASSCHE 11 Sept 1973 [11 Sept 1972] 42703/73 Heading E2A A coupling which may be used in safety belts and which automatically uncouples at a predetermined time after a heavy load has been applied and then released, comprises a tongue 5 secured by a rockable latch-bolt 4 connected to a sliding carrier 7 which is normally restrained by springs 6 against the loading on tongue 5, but which when forcibly displaced, pulls a hooked rod 9 against spring 13 causing a rack to wind up a delay 10, which on its return drives a rod 18 so that a spring on its shank tilts a lever 19 to release the bolt 4. The second rack 12 is not normally coupled to the releasing rod 18 but excessive displacement causes a spring-loaded latch-pin 16, Fig. 6, to engage a hole 14 near its end, thus linking them together until manually uncoupled so that the main coupling can be reengaged. The use of spring 20 means that the coupling will not release while it is still under load. A ramp surface 21, visible in Fig. 2, acts to reinsert the bolt 4 if a second load is applied as the bolt is being withdrawn. When the tongue 5 is withdrawn from the coupling, a feeler pin 24 allows lever 26 to rock so that its right-hand end lifts the head 17 of pin 16 to disconnect the rack 12. A slight modification is described.
