Title: Improvements in nuclear reactors
IPC: G21C3/32
Filed: 1961-11-07
Abstract: 992, 021. Reactors. BABCOCK & WILCOX Ltd. Nov. 7, 1961 [Nov. 8, 1960], No. 39775/61. Heading G6C. A nuclear reactor includes magazines containing bundles of fuel pins spaced from one another and the magazine wall by spacing means, and each magazine wall, which forms externally part of a pressure compartment, is constructed of thin metallic sheeting made flexible by flutes or corrugations so that a fluid pressure differential maintained between the compartment and a coolant flowing through the magazine serves to pack the spacing means tightly between and around the fuel pins. The flutes or corrugations 23 are also used to space the magazines apart. The spacers 28A, 28B and 28C (Fig. 3) which space the fuel pins 25 from one another and from the magazine walls 22, comprise short annular cylindrical rollers of identical length but different diameters, and are arranged in vertically spaced horizontal layers throughout the magazine 13. Each fuel pin is shouldered at its ends 26 for the rollers to rest on. The coolant is heated in the magazine 13, passed through a turbine, heat exchanger and pump respectively, and then recirculated through the magazine. The pressure compartment, which is contained in a pressure vessel, is pressurized by coolant fed through an opening in the pressure vessel from a point downstream of the pump. In Fig. 4 the coolant is not fed into the compartment 20 through the vessel, but is fed through a conduit 31. The conduit 31 has a flared mouth 32 adjacent a nozzle restriction 33 which causes high velocity coolant to enter the mouth 32 resulting in a pressure build-up within the conduit 31 which is transmitted to the coolant within the compartment 20. The pressurising conduits need not be supplied from the reactor coolant supply, but from special booster pumps which normally supply new coolant to the circuit. The new coolant can be fed to the compartment from which an overflow can open into the main coolant circuit.

IPC: G01B11/04
Filed: 1961-11-08
Abstract: 974, 234. Measurement of length by photo-electric circuitry. JONES & LAUGHLIN STEEL CORPORATION. Nov. 8, 1961, No. 40038/61. Heading G4H. In an apparatus for measurement of the length. of an article, e.g. a billet, photo-cells are used to detect the presence of the article and to develop a voltage proportional to the length. The article and photo-cells are moved continuously relative to each other. The photo-cells are arranged in two groups, the cells V-Z of one group being spaced apart by, for example, 5 feet, and the cells A-E of the other group being spaced by 1 foot. The billet 12 is passed from right to left along a conveyor and its leading edge is detected by cell 16. The resultant pulse is differentiated at 32 to set trigger 36 and to cause unit 38 to pulse. As a result, all the triggers 22 and 30, associated with the two groups of cells, are reset and all the gates 20 and 28 are opened. As the billet passes the cells A-E and V-Z the pulses from the cells, after differentiation at 26 and 18, set triggers 30 and 22. When the trailing edge of the billet passes cell 16 gate 34 is opened, and as the edge passes successively cells A, B, C.... triggers 30 are reset. When the leading edge reaches the next cell of the group V-Z, in the Figure this is cell Y, a pulse from the associated differentiator 18 passes through gate 34 to reset 36. All gates 20 and 28 are thus closed so no further triggers 22 and 30 can be set or reset by the photo-cells. Triggers 22 each give a voltage of 1 volt when set and triggers 30 give 0. 2 volts. Thus the sum of the voltages, in the illustration this is 4.4 4 volts, obtained from unit 46 and displayed by unit 48, is proportional to the length of the billet, which is therefore 22 feet in this example.

Abstract: 1387590 Severing by abrasion MONSANTO Ltd 20 July 1972 [26 Aug 1971] 40059/71 Heading B3D [Also in Division B5] A method of slicing a rod 24 comprises adheasively bonding one end of the rod to one end of an adapter piece 46, Fig. 1, having at least a portion of the same cross-section as the rod, placing the bonded rod in a rod-holding assembly 2, holding the bonded rod by a clamping means, relatively moving the rod and a saw 54 to slice the rod while supporting the slice being cut with a suction pick-up head, releasing the clamping means, returning the rod or saw, and advancing the rod relative to the saw blade plane in readiness for the next cut. In a machine for performing the method an annular saw 54 having an internal diamond edge is supported and rotated by a hollow spindle 55 mounted in a carriage which is reciprocated by an hydraulic motor 61. The rod holding assembly 2 comprises clamping means in the form of a pair of jaws 21, Fig. 2, which are pivotably supported in a cradle 12 which is itself pivotable about a vertical axis so that slices may be cut from the rod at an angle to the axis thereof. The cradle 12 is movable towards the saw blade plane by an hydraulic cylinder 7, and the rod and adapter piece are moved relative to the jaws 21, when these are open, by an hydraulic cylinder 39, Fig. 1, which moves a rack 38, Fig. 2, to cause rotation of a nut 36 via a one-way clutch 35 and thus cause a lead screw 37 attached to the adapter piece 46 to be advanced by a distance equal to the thickness of a slice plus the saw kerf. The suction pick-up head comprises a grooved rubber pad having a central aperture through which vacuum may be applied or released or air blown. Air is blown to clean the free end of the rod before the head is secured thereto by vacuum, and the vacuum is released to drop a slice cut from the rod into, e.g. a container of water. The cut slice and rod are withdrawn from the plane of the cut before the saw blade is retracted to its initial position.
