Title: Improvements in or relating to the manufacture of rods
IPC: C30B13/30
Filed: 1965-12-10
Abstract: In a process of floating-zone melting, a rod of constant diameter is produced by continuously measuring the diameter of the solidifying interface and the volume of the molten zone; continuously comparing with the desired constant diameter and a variable volume setting, respectively; continuously adjusting the measured volume to the set volume (initially set to approximate to the desired value) by stretching or compressing the ends of the rod; and continuously causing any deviation in diameter from the desired value during zone-melting to alter the comparison volume setting so as to correct the deviation.  The diameter may be measured by a television camera. The volume may be measured by means of an induction coil.  According to the Figure (not shown), a molten zone 2 is produced in a rod 1 by an induction coil 3.  A coil 5, just below coil 3 and a measurement converter 6 form an electric oscillation circuit system which provides a direct current signal to a controller 8.  A similar signal is supplied from a volume setting device 9 and any difference causes operation of means 4 for stretching or compressing lower end 1b of the rod. The diameter of the solidifying interface is measured by a television camera 11 connected to a measurement converting device 12 which supplies a direct current to a controller 13.  A similar signal is supplied from a diameter setting device 14 and any difference causes alteration of the setting of device 9.

Title: Improvements in or relating to containers for radioactive materials
Inventor: LECUYER DANIEL
IPC: G21F5/02
Filed: 1967-12-08
Abstract: 1,206,767. Radio-active source container. D. LECUYER. 8 Dec., 1967 [20 Dec., 1966], No. 56044/67. Heading H5R. In a source container, a shielded position and exposure position are available for the source with a conduit allowing movement between the two, the arrangement being such that on withdrawing the source into the shielded position, the conduit is automatically blocked and the presence of the whole of the source in the shielded position is verified there being means for producing an alarm signal if the returned source is not of the correct size. The blocking or obturating member 8 is preferably slidable along the conduit away from the source when it is being exposed, being then displaceable laterally to exposure the source, this lateral movement being linear (Fig. 12, not shown) or a rotation e.g. about axis 9 (Fig. 3), the obturator being supported in a suitable carrier. Preferably the obturator 8 is received into one tube 10 of two tubes 10, and 11 supported by a cradle 9 pivoting about axis 9a, the tube 11 being adapted to receive the source during exposure. The pivotal movement of the cradle 9 and the translatory movement of the obturator 8 may be accomplished using a rotary cam 13 having a slot 18 in which a stub 19 attached to the cradle operates, the cam also having a pin 14 which co-operates with slot 15 in lever 16 to accomplish the translatory movement of obturator 8. In Fig. 2 and Fig. 3 the exposed position is shown in full line the shielded position in chain dotted line. It is preferred that the arrangement be such that the cradle 9 cannot be rotated from the exposed position until the source has been withdrawn from it. In returning to the shielded position the obturator 8 is arranged to contact the source, and the end of the lever 16 occupies a certain position according to the length of the source. Any deviation from the normal position may be adapted to activate an alarm system, and if desired the normal position may activate one type of signal, the abnormal a second signal (Fig. 7, not shown). The cam 13 is operated by a ratchet 22 and sprocket 21 which turn axle 20 (shown in section in Fig. 3). The cam 13 may be held in the exposed position against a spring loading of ratchet 22 by a spring loaded pawl 31 which operates via lever 33 against a stop (not shown). The movement of the cradle and the replacement of the obturator may be made to be automatically dependent on the return of the source by ensuring such return releases the stop.

Title: Improvements in or relating to gas pressure regulators
Inventor: FARRER SYDNEY
IPC: A62C4/02
Filed: 1967-12-12
Abstract: 1,212,520. Valves. BRYAN DONKIN CO. Ltd. 10 Dec., 1968 [12 Dec., 1967], No. 56382/67 Heading F2V. In a valve which is adapted to regulate pressure when such pressure lies between predetermined upper and lower values and to cutoff flow when such pressure rises above, or falls below the predetermined values, regulation of pressure is effected by a valve member 80 which co-operates with a seat formed about a port 72 whilst cut-off is effected by a valve member 84 which co-operates with a seat formed about a port 74, the two valve members being interconnected by a spindle 83 and the two ports interconnected by the bore formed in a plug 70 which is disposed in a wall 66 separating the inlet 62 from the outlet 64. An extension 60 of the spindle 83 is connected, through an operating lever 92, a trip lever 94 and a link 96, to a diaphragm 32, the underside of which is subjected, via ports 65, to pressure at the outlet, the operating lever being pivoted at 116, and the trip lever being pivoted to lever 92 at 102 and to link 96 at 100. A spring 104 extends between the pivot point 100 and a pin 106 and, under normal regulating conditions, extends below pivot point 102. With the fluid pressure within the predetermined valves, the pressure at the outlet 64 acts on the diaphragm which in turn correspondingly actuates valve member 80. Upon such pressure falling below the lower predetermined value, spring 47 moves the diaphragm downwardly and hence, via the link and levers, moves valve member 84 on to its seat, Fig. 3 (not shown). In the event of the pressure rising slightly above the upper predetermined value, diaphragm 32 moves upwardly so causing lever 92 to pivot in an anticlockwise direction and hence valve member 80 to be seated, Fig. 2 (not shown). A further pressure increase results in spring 104 moving to the other side of pivot 102 and hence, by virtue of the arrangement of pivot points and the spring tension, forcing cut-off valve member 84 on to its seat, Fig. 4 (not shown). Re-setting of the valve, subsequent to valve member 84 being seated, is effected by appropriate manipulation of diaphragm stem 40.

[Also in Division F4] Underwater ejection apparatus for a buoyant aircraft crash recorder container comprises a housing 2, Fig. 1, for the container 7, 8 accessible through an opening normally closed by a cover 4, a spring-operated device 21 under the control of a pressure sensor 10 which, on sensing a predetermined pressure, e.g. corresponding to a depth of 25 to 35 feet, causes gas to be released , from a high pressure source 9, and a telescopic ejection device 36-39 for ejecting the container 7, 8 through the opening together with the cover in response to the release of gas. The recorder container 7 in its buoyancy container 8 are mounted In a cylinder 5 and located therein by a pin 29. The pressure sensor 10 is fixed to the cylinder 5 and has a piston movable against a spring to push a pin 11 outwardly against a toggle linkage 12-15 (Fig. 2). Continued movement of pin 11 in direction of arrow A moves the linkage over-centre. Through linkage 12, 20 and spring linkage 22, 24, a circular plate 21, secured to an end wall 6 of cylinder 5, is rotated clockwise. A lever 25 on plate 21 is brought into contact with a pivotable lever 26 having a pointed end 28, and moves lever 26 anticlockwise so that part 28 ruptures a membrane in compressed air cylinder 9. Simultaneous movement of link 24, through a link 33 causes withdrawal of pin 29 so that the container 7, 8 is no longer fixed to cylinder 5. The air is fed through pipes 35 into passages in pistonrods 36, out through the piston-heads 38 where it acts against plugs 39 on cylinders fixed in container 8 and against pistons 38 to push the container 7, 8 out of the housing. The cover 4 is locked by four equally spaced ball locks 43, 44. As the container 7, 8 is moved, striker pads 46 contact a plunger 41 which is moved within the cover to move a member 42 away from a ball 43 which ball then moves out of contact with a member 44 to release the cover 4. To enable the pressure sensor to operate, holes 80, 81 are provided to allow cylinder 5 to flood quickly. A radio beacon on the recorder container is automatically switched on as it moves out of its housing by a means 57, 58 fixed to the wall 6 of cylinder 5.
