Title: Underwater container assembly
IPC: B63B35/44
Filed: 1963-02-26
Abstract: 974,576. Marine storage vessels. D. O. ALEXANDER. Feb. 26, 1963 [Feb. 26, 1962], No. 7663/63. Heading B7A. [Also in Divisions B8 and E1] A submersible package includes an inflatable membrane 12 of a size to fill, when inflated, an outer container 14, and a commodity 10, which may be in a box, within the membrane. The package may include a gas bottle 34 for inflating the membrane, and control devices, operable by radio or sonar, or by a time mechanism, to release an anchor on the container and to initiate inflation of the membrane. Inflation of the membrane may also be controllable manually. The pressure of inflation may be under the control of devices sensitive to the pressure within the membrane and to the external hydrostatic pressure, and the control may be such as to provide the buoyancy necessary to maintain the package in equilibrium at a predetermined depth. A relief valve may release the air or gas inflating the membrane as the package approaches the surface. The vents 16 shown in the outer container 14 may be replaced by valves opened by the pressure of the membrane when this is inflated. The package may include handling hooks 17. It may also have a propulsion means 55, and may be in the form of a sled, or have tracks, wheels or skids, and may be in the form of a boat or of a boat landing craft. The membrane may be adapted to be thrown away after each use. The Specification suggests suitable materials for the outer container 14 and for the membrane 12.

Title: Reactor control rod system
IPC: H01L29/00
Filed: 1964-02-24
Abstract: 992,482. Reactor control rods. UNITED STATES ATOMIC ENERGY COMMISSION. Feb. 24, 1964 [May 6, 1963], No. 7681/64. Heading G6C. A nuclear reactor control rod drive system for vertically disposed control rods comprises a tube mounted above and in axial alignment with the control rod and having an internal diameter which increases in the direction away from its end adjacent the control rod, means for providing a variable fluid flow upwards through the tube, a float member disposed in the tube and adapted to vary its position in response to variations in the fluid flow rate, and means coupling the float and control rod to enable changes in the position of the float to produce corresponding changes in the position of the control rod. The reactor is gas cooled and its core comprises small graphite spheres containing U 235  which are loaded into the core through tubes 13 and unloaded through tubes 27. Coolant enters a lower plenum chamber 20, passes up through a steel support grid 14 and a lower reflector 9 into the core. Hot coolant passes through an upper reflector 10 and through a plenum chamber 23 to a steam generator 5, from which the cooled coolant passes through an outlet 6 to chambers 26 and 28, before returning to a circulator. The control rods and drive system comprises a tapered tube 34 through which coolant gas is drawn upwardly by a centrifugal pump 37, gas entering the tapered tube 34 from inlet holes 33a in a control rod guide tube 29, and from its lower end; the flow through the guide tube cools the neutron absorbing control rod. A float 40 is attached to the control rod by a cable 44, and a differential transformer 43 mounted alongside the tapered tube 34 provides signals indicative of the control rod position. Stops 41 and 42 limit respectively the downward movement of the float and the upward movement of the control rod. Characteristics of the system may be varied by using different degrees of taper in the tube 34, including the use of small and large angle tapers in the same tube to give more sensitive control over the normal operating range; the system is fail-safe. It is possible to dispense with the pump 38 and use gas to direct from the circulating blower, exhausted to a low pressure part of the reactor; in this case, control rod position is varied by means of a throttle valve.

Title: Oil filter
Inventor: BROWN RICHARD EVERETT
IPC: B01D27/00
Filed: 1957-03-08
Abstract: 815,349. Filters. AIR-MAZE CORPORATION. March 8, 1957, No. 7727/57. Class 46. A filter housing has inlet and outlet conduits communicating with it, a partition in the housing between the conduits, a filter element extending through an opening in the partition, and an axially extending-sealing member fixed to the filter element and telescopically engaging the edge of the opening in the partition to seal the opening in all positions of the sealing member, the sealing member forming a seal with the partition of such extent as to remain effective even though the filter element be subject to axial movement. A perforate tube 18 carrying filter leaves 19 has rigidly secured thereto a cylindrical member 22 having an annular groove 22a in which is located an 0-ring 23 of rubber or the like to provide a seal between the member 22 and a sleeve 24 rigidly secured in an aperture 15a in a partition 15. The extent to which the filter element may be inserted into the space beneath the partition (the inlet space) is governed by a plate 25 rigidly secured to the tube 18 and normally resting on the partition. The length of the tube 18 and the position of the plate 25 are so chosen that between the upper end of the tube and a cover 13 only a small clearance 27 is left. The axial extent of the seal provided by the members 22, 23 and 24 is so chosen that when clogging of the filter leaves occurs and the consequent increase of differential pressure operates on the under-surface of the cylinder 22 to raise the tube 18, the 0-ring 23 remains in engagement with the sleeve 24 when the upper end of the tube has come into contact with the cover. A plate 26 is included between a nut 20 and a cup 30 (clamping the leaves 19) so as to protect the lower leaves from damage on inserting the element, and to cooperate with the plate 25 to protect the leaves and the cylindrical member 22 from damage when the element is laid down after removal from the casing 10. Three such elements are provided in the casing.

Filed: 1958-03-11
Abstract: 884,298. Nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 11, 1958 [March 18, 1957], No. 7761/58. Class 39(4) A gas-cooled reactor having vertical channels 19 in a graphite core 40 accommodating fuel elements or control rods, has a number of tubes 3 movably mounted in the biological shield 1, each tube serving a group of channels. For example, when a tube 3 is moved opposite a control rod channel it provides a passage for the cable supporting the rod (Fig. 2, not shown) whereas when it is positioned opposite a fuel element channel it may serve as a passage for lowering inspection equipment into a channel having a jammed fuel element and for lowering a grab to retrieve the fuel elements from that channel. The required movements of the tube 3 are obtained by slidably mounting it along an axis Z-Z in a plug 5 rotatable about an axis Y-Y in a plug 4, the plug 4 being rotatable about an axis X-X. The three axes intersect at O and the flared entrances of the channels 19 of the related group converge towards the point O. The tube 3 is moved longitudinally by a pinion 13 operating on a rack and may be closed by a valve 14 operated through a shaft 16. Specification 869,539 is referred to.
