Title: Nuclear fuel sub-assembly - with outer jacket expansion chamber for gaseous fission products
IPC: G21C3/32
Filed: 1966-08-12
Granted: 1971-07-12
Abstract: Nuclear fuel sub-assembly of the multi-pin cluster type where the ends of the fuel pins fit into a honeycomb grid of collars; the collars being joined together by members having internal passages which connect the free spaces in the fuel pins' casings with an expansion chamber formed in the wall of a jacket enclosing the multipin cluster. By providing this additional space into which fission gases from all the pins can expand during operation of the reactor, it is possible to obtain a marked increase in thermal output by employing higher temperatures without over-stressing the fuel pin casings.

Abstract: 1,051,315. Holders for X-ray film. L.L. DECROP. Feb.19, 1964 [July 11, 1963], No.6934/64. Heading G2A. A casing for X-ray film contains built-in supplies of developing and fixing salts in solid form, so that the film can be processed in situ merely by adding water. The casing 1 is made of a plastics material that can be joined by heatseaming. Such a seam is made to form a wall 18 having a sloping lower portion 54. Wall 18 divides the casing into two compartments 16, 17, containing developing and fixing salts 21, 22 respectively. The narrow portion between the lower end of wall 54 and the wall of casing 1 is temporarily closed by a flexible grip 55. The bottom end of the casing is divided off from the remainder by a seamed wall 2 to enclose a compartment 50 which holds the plate or film 9. The flat casing walls on each side of the film have punctiform projections to support the film centrally and so allow free flow of liquid round it. In the upper corner of compartment 50 is an exit orifice 51. When water is poured into the casing through an entrance orifice (not shown), both solutions are formed together. The fixing solution is closed off by grip 55, so that only the developer solution flows down the casing and through gap 53 to reach the film. After development, grip 55 is removed, so that the fixing solution can now run down and fill compartment 50. Figs. (not shown) 2, 3 and 10 are modifications having different arrangements of the separating walls. In Fig. 10 the entrance and exit orifices are the same, and the casing is emptied by inverting it. Figs. (not shown) 4-9 illustrate how the casing may be folded up for convenience.

Abstract: 1,054,054. fluid analysing apparatus. HONEYWELL Inc. June 4, 1963 [June 1, 1962], No. 22204/63. Headings G1A and G1N A fluid analysing apparatus comprises a tank including a means responsive to a physical characteristic of the fluid within the tank, the tank being positioned within and spaced from the walls of a container the capacity of which is such as to provide a space many times greater than the volume of the tank, and fluid passageways being provided so that a sample may pass through the base of the tank through an opening in the upper wall, and out through a drain in the upper wall of the container. The invention is applied to an apparatus for testing river water in which samples may be drawn from predetermined depths by a pump 44, Fig. 1 (not shown), and wherein the container holds six tanks 102, 104, 106, 108, 110, 112 each including a probe, the respective probes measuring temperature, turbidity, pH, chloride ion conductivity, and dissolved oxygen content which are recorded on a single chart together with sunlight intensity on the river which is measured by a separate transducer 135. The pump 44 is suspended from a shaft 30 mounted on a float 12 and apertures are provided in the shaft supporting bracket wherein pins may be located to fix the pump at a desired angle. A proportion of the pumped water is fed back to the river through a manually adjustable valve 60. The fluid is fed to the tanks through a manifold 74 and the inlet ends within thetank may be screwed for the provision of nozzles such as 124, Fig. 3, so that the initial spray may be directed on the probes for cleaning purposes. Sand filters may be incorporated in the manifold. Apertures 150, 152 provide for the egress of water and the size of the space to which the water flows ensures a good representative sample in the tank. An overflow 174 is provided in the outer container, and a drain 178 controlled by a solenoid operated valve 180 is provided for cleaning purposes. The control circuit provides for samples to be bottled in the event of characteristics exceeding predetermined limits. The turbidity meter comprises a light 280, Fig. 3 (not shown), directing light on to the surface of the tank sample through a lens 282 the reflected light from the water being detected by one or more photo-cells 288 around an aperture 284. An analogue to digital converter may precede the recorder. The process is controlled by cam operated mercury switches in response to a timer, and the measuring is initiated by a floating level switch in the container.

Abstract: 1,144,323. Rotary positive - displacement fluid pumps and motors. CHAR-LYNN CO. March 22, 1966 [Aug. 4, 1965], No. 12655/66. Heading F1F. A rotary-piston pump or motor, comprises an externally-toothed piston or star member 18 that is rotatable in a planetary manner relative to an internally-toothed ring-member 6, working chambers or cells 39 to 44 being cyclically connected to inlet and outlet ports 14, 16 for the working fluid by a rotary valve-element 28 fixed to a power input, or output, shaft 30 and coupled to the piston by a splined shaft 58. A plurality of axially-orientated passages 91 to 97 in a section 4 of the casing connects the working spaces to one end of a bore 20 containing the element 28, and two sets of passages 71 to 76 and 81 to 86 in the element 28 are periodically and sequentially brought into register with the passages in the section 4 when said element revolves, the two sets of passages being connected to the ports 14, 16, respectively, by annular grooves 64, 66. Tilting of the element 28 due to pressure exerted by the working fluid on an end face 34 of said element in regions adjacent the passages that are either partially or wholly in register with the passages in the section 4 is obviated by dummy passages, which are constituted by recesses 101 to 107 and located in said section. In another embodiment, Figs. 5 to 8 (not shown), the piston (122) is fixed to a rotatable power input, or output, shaft (126) and the ring member (124) is rendered capable of gyrating about the polar axis of the piston without revolving about its own axis, the valve element 28 being replaced by a valve element in the form of a circular plate (132) that is fixed to the ring member and co-operates with an inmovable plate or casing section (111) containing a plurality of pairs of radially-orientated slots (1X, 1Y to 7X, 7Y). The slots (1X to 7X) are connected to an inlet port (114) whereas the other slots (1Y to 7Y) are connected to an outlet port (115), radial slots (1G to 7G) being formed in the plate (132) and connected to the working spaces by axial passages (152). Dummy slots (164) between the slots in the plate (111) and further dummy slots (X and Y) between the pairs of slots in the plate (132) prevent tilting of the latter due to the pressure of the working fluid, the slots (X and Y) being connected to the ports aforesaid, respectively, by annular channels (154, 156) and axial passages (166, 168) in the plate (111). The motion of the ring member is controlled by a plate (130) attached thereto and having a pair of axially-orientated studs (147, 148) lodged in rectangular slides or boxes (143, 144) that slidingly engage with rectangular recesses (141, 142) within the casing.
