Title: Standpipe arrays
IPC: G21C13/02
Filed: 1971-02-05
Abstract: 1374482 Reactors BRITISH NUCLEAR DESIGN & CONSTRUCTION Ltd 7 Feb 1972 [5 Feb 1971] 4101/71 Heading G6C A standpipe array for a reactor having a core composed of a plurality of parallel columns comprises a fuelling standpipe 10 in respect of a group of the columns and one or more control red standpipes 14 (only one shown) disposed adjacent to the fuelling standpipe 10, the or each control rod standpipe 14 being arranged to serve a respective one of the columns in the group, and the fuelling standpipe 10 having internal dimensions sufficient to permit passage through the standpipe of each of the columns in the group. Where the columns are hexagonal in cross-section (Fig. 1, not shown), each group of seven columns is served by a single fuelling standpipe 10, the axis of which coincides with that of the central column of the group, and six control rod standpipes 14 disposed symmetrically around the standpipe 10. The standpipes 10, 14 extend through the top cap 18 of a concrete pressure vessel surrounding the reactor core. Provision is made for cooling the control rod standpipes 14 by means of an annular water jacket 22 having inlet and outlet pipes 24, 26. In fuelling a homogeneous core, each of the blocks forming the core columns may be removed by lifting it clear of the core, shifting it laterally into line with the fuelling standpipe 10, and then withdrawing it. The control rod standpipes 14 are cranked outwardly near their upper ends with respect to the fuelling standpipe 10 to avoid obstruction of a fuelling unit latched on to the upper end of the standpipe 10. Alternatively, each standpipe 14 is inclined outwardly from its lower end. During fuelling operations through a fuelling standpipe 10, it is only necessary to remove one, or at the most two, control rods from the core, these being the control rod disposed in the column to be removed and the control rod, if any, which is disposed in or above the centre column of the group. Thus throughout fuelling operations an adequate potential neutron absorbent capacity in the form of control rods remains available for use.

Title: Improvements relating to lights for guiding aircraft
IPC: B64F1/20
Filed: 1941-04-05
Abstract: 547,345. Signalling by visible signals. CHANCE BROS. & CO., Ltd., and HOLMES, J. G. April 5, 1941, No. 4575. [Class 118 (ii)] A device for guiding aircraft consists of a light-projecting apparatus with a moving screen which bears a pattern that interrupts the light beam and projects flashes. The pattern is so arranged that the sequence of flashes seen by the pilot of an aircraft differs according to the position of the aircraft relatively to the projector. In one construction, the apparatus comprises an electric lamp a, Fig. 2, a reflector b, a condensing lens e, a projecting lens c, and a screen consisting of an endless band d of opaque flexible material carried by rollers h one of which is driven by a motor. The band d has transparent or translucent portions arranged in a pattern as shown in Fig. 3, to provide groups of signal flashes. The parts of the pattern between the lines 1, 2 give a succession of equally-spaced dot flashes, the parts between the lines 2, 3 give a sequence of dot and dash flashes, and the part between the lines 3, 4 give a sequence of groups of flashes. The image of the pattern is projected upwards, and a pilot of an aircraft knows that he is on his proper course if he sees the flashes emitted by the central part of the pattern. Deviation from the course will bring him into the regions covered by the outer ports of the pattern. The screen may reciprocate instead of being driven in one direction, or it may consist of a rotating disc. In another form, the pattern may be formed on a frusto-conical screen j, Fig. 5, or on the edges of two such screens, or rotating discs, which touch or overlap one another on the optical axis O-A of the projecting lens.,

Title: Microwave transmission system
IPC: H01P5/08
Filed: 1951-02-26
Abstract: 676,947. High-frequency transmission lines. STANDARD TELEPHONES & CABLES, Ltd. Feb. 26,1951 [May 23, 1950], No. 4645/51. Class 40 (viii). A single line conductor 1 used for microwave propagation by means of an electromagnetic field formed thereabout is coupled to a hollow conductor 3 by being extended therein. The end portion of the conductor 3 may be caused to decrease progressively in conductance towards its end to improve matching. This may be effected as shown by tapering the wall of conductor 3, or alternatively the conductivity of the conductor may be varied, for example by spraying resistance material thereon. Conductor 3 may be a wave-guide or, as shown, it may form the outer of a coaxial line, the inner of which is a continuation of conductor 1. The latter is generally covered with insulation to maintain its surrounding field within desired limits and, as shown, this insulation may include beads 10, 11, 12, and 13. By altering the spacing of the beads or otherwise varying the insulation the insulation per unit length may be arranged to decrease progressively in each direction along conductor 1 from the point of entry at bead 10 into conductor 3. This effects a desirable contraction of the field about conductor 1 at its point of entry into conductor 3.

Abstract: 926,064. Filters; presses for separating liquids from solids. J. WILLMES. Feb. 8, 1961 [Feb. 12, 1960; Dec. 20, 1960], No. 4691/61. Class 46. [Also in Group XIII] A press drum which may be rotatable comprises staves 3, a fixed end platen 1 and a platen 5 mounted for movement towards the platen 1 on a threaded spindle 10 in an internally threaded member 7. Ribbons 14 extend between the platens and ribbons 13, Fig. 2, wider than the ribbons 14, are placed in overlapping manner along the internal face of the drum to provide flow channels for the liquid pressed out of material introduced into the drum through a door 2<SP>1</SP>; the ribbons are of a fibrous capillaryactive material. The ribbons 14 extend along substantially straight lines when the platens are at their greatest distance but movement of the platen 5 allows the ribbons 13, 14 to touch and create a continuous sytem of channels to allow discharge of moisture through apertures between the staves 3. Reversal of movement of the platen 5 straightens the ribbons to comminute the material. In a series of modifications, Figs. 3 to 7 (not shown), the ribbons 14 may be (a) arranged in radial planes offset by equal angles about the axis of the drum (b) replaced by a large number of closely spaced fibrous ropes (c) arranged to extend in planes parallel to the axis of a drum of rectangular section and at right angles to a removable wall therein (d) replaced by two ribbons extending axially between the end platens in a drum of square cross-section, which ribbons are connected by axially spaced transverse ribbons, and in a final modification (e) the axially extending ribbons of modification (d) are secured to carrier plates slidably inserted in grooves formed on the two end platens. Means for securing the ribbons to the platens without the use of carrier plates comprise hooks or threaded studs on the platens which engage eyes carried by the folded ends of the ribbons, and the rope-type ribbons are secured at the ends of the drums by carrier plates mounted in spaced relation to the platens to provide a drainage space. The ropes comprise several strands of a continuous length of material skeined to form several loops which are inserted through apertures in the carrier plates and held in position by rods or rings and the rope may be combined into a bundle or groups within the drum by the use of further rings.
