Title: Fluid pressure actuated operator cylinder with incorporated stress converter
IPC: F15B15/00
Filed: 1975-09-25
Abstract: 1502980 Hydro-pneumatic intensifiers REUTI ANSTALT 25 Sept 1975 [10 Oct 1974 4 Aug 1975] 39234/75 Heading F1D In the device shown in Figs. 1 and 2, when compressed air is admitted through a port 11, a piston 8 and rod 9 are moved to the right by the combined action of air acting directly on the piston and by hydraulic liquid acting on the lefthand end 19 of the piston-rod. A free piston 13 transfers the air-pressure to hydraulic liquid and this is forced through ducts 14 to act on the pistonrod 19. When the rod 9 has been moved the desired distance at a relatively high speed with a low-pressure, e.g. up to a workpiece, compressed air is admitted through a port 22. This moves a piston 20 with a rod 21 to the right. After a small displacement, the rod 21 closes ducts 14 and the piston 20 and rod 21 act as an intensifier and move the piston 8 and rod 9 to the right with greater force. Fig. 5, (not shown), illustrates the final position. Fig. 7 shows a simplified embodiment in which the piston 8 is omitted. Air-pressure applied to the port 11' acts on the piston 19 through a free piston 13' and hydraulic liquid which passes through ducts 14'. The intensifier section 20', 21', operates as previously described.

Title: Improvements in and relating to nuclear reactors
Inventor: BOWDEN ANDREW THOMSON
IPC: G21C1/20
Filed: 1956-12-28
Abstract: 820,579. Nuclear reactors. PARSONS & CO. Ltd., C. A. Oct. 16, 1957 [Dec. 28, 1956], No. 39410/56. Class 39(4). In a liquid moderated liquid cooled reactor, the nuclear fuel is housed in a plurality of re-entrant tubes each comprising an inner tube and an outer tube, the inner tube containing the fuel, and the liquid coolant being circulated through a space between the inner and outer tube and thence through the inner tube to cool the surface of the fuel. In the reactor shown in Fig. 1 re-entrant tubes each comprising an outer tube 3a and an inner tube 3b are disposed in a liquid moderator 2 which may be heavy water. A cooling liquid, preferably a diphenyl or a triphenyl, is introduced at an inlet 4 to each tube 3a and flows downwardly between the inner and outer tubes and then upwardly through the inner tube 3b past fuel element 6. Preferably the liquid has a lower velocity when flowing downwards than when flowing upwards to reduce heat transfer to the moderator ; the tubes 3a may incorporate gas spaces to further reduce the heat transfer to the moderator. The heat transfer to the moderator may thus be kept at a level which prevents boiling without the need for pressurizing. The re-entrant tubes may be connected in parallel to supply and exhaust mains through which coolant is circulated by a pump in a closed pressurized system.

The member 7 may be a screw but as shown is in the form of a nut having a threaded bore for engagement with a screw 1 passing through a bore 3 in a plate 5. In use, the nut 7 is screwed on to the screw 1 by gripping the element 13 and when the frustoconical foot 21 of the nut engages the plate with a predetermined force the element 13 disengages the stop 17 to rotate relative to the nut 7 along co-operating threads 11. If desired continued rotation of the element 13 brings frusto-conical surfaces 23, 25 into abutment and produces inward radially applied pressure on the screw shank and thereby locking engagement of the nut to the screw 1. The stop 17 may be formed by a rolled-over or bent-over portion of the nut 7 or by an enlarged threaded outer portion of the nut 7 or by separate stop nuts screwed on to the nut 7.

A multi-cut copying process comprises automatic means for moving a feeler and a template relatively to one another at the end of each preliminary cut to increase the depth of cut of the tool and includes a switch, operated by the return of the tool to the starting position, which is maintained out of operation for the final cut when the whole of the operative edge of the template is traversed by the feeler. In a first embodiment in which a feeler 2, Fig. 1, is moved stepwise away from a template P, fixed to a lathe bed, to perform a number of preliminary cuts on the work, the hydraulic copying slide is of a known form and the feeler is supported on a scissors like mounting Y which is moved automatically at the end of each cut to increase the depth of cut. The feeler Q, Fig. 15, moves parallel but away from the straight parts of the template P during preliminary cuts and only touches the template when the shoulders thereon are reached. A switch on the template support is then operated to withdraw the tool and return it at a rapid traverse to a fresh starting position. This cycle continues as shown by the broken lines until the feeler contacts the straight parts of the template when the whole template form is copied (as shown in the drawing vertically hatched) and the tool slide J, Fig. 1, moves through a complete traverse up to the stop Z. In a second embodiment a similar stepwise control device and support Y, Fig. 16, pivots the template P, mounted on a lever 57 for a series of preliminary cuts. The final cut is effected when the template lever reaches a stop 58. Two forms of the stepwise control device for the feeler are illustrated in Figs. 2 and 4 (not shown).
