Title: Liquid-metal cooled nuclear reactors and rotary pump assemblies therefor

IPC: G21C1/03
Filed: 1965-03-31
Abstract: 1,137,865. Lubricating; seals; pipe joints. ENGLISH ELECTRIC CO. Ltd. 29 March, 1966 [31 March, 1965], No. 13711/65. Headings F2A, F2B and F2G. [Also in Divisions F1 and G6] In a pump assembly (see Group F1) for circulating cooling liquid metal, e.g. sodium, potassium or a mixture thereof, in a nuclear reactor (see Group G6), the pump drive shaft 37, Fig. 5, is supported in a journal bearing 75 and a journal and a thrust bearing, 57, 58, Fig. 3. The bearing surfaces may be coated with a hard, non-ferrous metal alloy, and the thrust bearing may be of the Michell, roller or collar type. Liquid metal from the reactor is circulated through the bearing 75 via passages 79, 80 and through the bearings 57, 58 through passages 59, 60. Upward leakage of liquid metal past the bearing 75 is removed through passage 85. To prevent liquid metal from leaking into a vessel 30 a labyrinth seal 81 is provided. Any liquid metal leaking past the seal 81 passes into an annular space 90 where the liquid metal is caused to freeze by the cooling action of an inert gas, e.g. argon, circulated through an annular space 95 via passages 94, 96. A double gas seal 84 is provided. In an alternative embodiment, Fig. 4 (not shown), the annular spaces 90, 95 are omitted and the inert gas is supplied to a lantern ring (83) beneath the double gas seal (84) and above a retaining plate (82), the gas being pressurized to a value greater than that of the liquid metal to assist sealing. A flange on the discharge side of the pump assembly is attached to a connector 66, Fig. 3, via a bellows 64 and a number of tie bolts 70 forming clearances 73, to permit relative thermal expansions and contractions. The connector has a frustoconical female portion (67), Fig. 2 (not shown), at its lower end which receives a complementary male portion (68) at the upper end of a discharge pipe (16), the two portions being secured together by cam-type clamps (69) operated externally of the reactor by a mechanical linkage.

Abstract: 468,808. Valve generating circuits. RADIOAKT.-GES. D. S. LOEWE. May 15, 1936, No. 13749. Convention date, May 16, 1935. [Classes 40 (iii) and 40 (v)] Impedances 13..20, which improve the transmission of low frequencies, are inserted between the deflecting plates or coils of a cathode-ray tube for television reception and a relaxation oscillator 3, which is succeeded by an amplifier 12. All the resistance-capacity combinations 4.. 11 in the coupling circuits have a time constant greater than the period of scanning one complete image. The correcting impedances consist of condensers and resistances in parallel and in series with the resistances 1, 8, 21, 10, 11. The time constant of the condenser-resistance circuit 13', 14, which smooths the grid bias of the amplifier, is so selected as to eliminate the drop in voltage at the low frequencies. Specifications 442,740, 454,471, and 465,184, as open to inspection under Sect. 91, are referred to. The Specification, as open to inspection under Sect. 91, also comprises the use of deflecting coils, the time-constant of which is at least ten times the period of scanning one image. This subject-matter does not appear in the Specification as accepted.

Title: Apparatus for sorting radioactive ore
IPC: B07C5/346
Filed: 1949-05-24
Abstract: 658,572. Valve relay circuits. ELDORADO MINING & REFINING (1944), Ltd. May 24, 1949, No. 13855. Convention date, June 1, 1948. [Class 40 (vi)] [Also in Group XL (b)] The output pulses of a Geiger counter are integrated to trigger a thyratron, the thyratron operating a circuit which holds the thyratron fired for a sufficient length of time to operate a sorting mechanism for radioactive particles. As shown, a shielded Geiger tube 16 situated along the belt receives radiation from the particles and applies a series of negative pulses to the grid of an amplifying triode 33. The resulting positive pulses at the anode are fed to the grid of a second triode 43 having a common cathode resistor with the first triode so that the positive output pulses are increased in amplitude. The impulses are integrated across a condenser 51 so that when grid 49 of a further triode 50 reaches a predetermined build-up voltage the output voltage across a cathode resistor triggers a thyratron 59 to operate a A.C. feed relay 53. This relay 53 firstly connects the cathode of a triode 71 to the grid of tube 50, secondly supplies a positive pulse of predetermined length to the grid of tube 71 and thirdly connects a "kicker" to the supply to eject the radioactive particle from the belt. The length of the positive pulse applied to the grid of tube 71 is determined by condenser 72 and a preselected one of resistors 75, 76 and 77. If the cathode output potential of tube 71 is only a little less than the potential of grid 49 in the absence of a signal the firing time of thyratron 59 is increased so that the "kicker" operating pulse is sufficiently long to actuate the "kicker" satisfactorily. The cathode potential may be adjusted by variable resistor 83 and the thyratron sensitivity by resistor 64 forming part of a bleeder chain.

Title: Construction of reciprocating engines

Abstract: 419,948. Cylinders, framing, &c. ROBINSON, G. H., 11, Wigan Road, Westhead, Ormskirk, Lancashire. May 18, 1933, No. 14449. [Class 7 (ii).] A cylindrical member in which reciprocating movement takes place in a reciprocating engine, pump, or the like is made by splitting one end of a metal tube, opening the split portions, and connecting one or both portions to the crank-shaft bearing or bearings. In the four - stroke internal - combustion engine shown, each cylinder 1 is made by splitting the end of a tube of steel or an alloy of magnesium or aluminium, opening and flattening the split portions 2, flanging the edges 3, and tucking and welding them into grooves in half-sleeves 4, forming half-bearing housings. Longitudinal stiffening- webs 33 which may extend through the crank case to the half-sleeves, are welded between the cylinders, which are preferably chromium-plated to a thickness of <1>/100 in. In a multicrank engine in which there is no bearing between each crank pin, some of the cylinders have no split portions and are retained by the webs 33 and by welding to the upper half of the crank case. The lower half of the crank case is formed by a pan 53 which is bolted on to the upper half through welded-on bosses 54 joined by stiffening-webs 55. The top half 6 of the crank case is welded to the cylinders and comprises two plates 7, 8 connected by longitudinal webs 9 and transverse webs 10, which are welded to the inner plate and provided with tongues 11 passing through slots in the outer plate 8, so that they can be welded to the latter plate from the outside. To stiffen the cylinders laterally, one transverse web 10 on each side of each cylinder is extended upwards as at 10a, and two of these are extended laterally to form a seating 12 for a dynamo or other auxiliary, and further stiffening-webs 59 are welded between the plate 7 and the edges of the split portion 2. End plates 13, 14, formed of steel pressings or built up by welding steel plates and stiffening- ribs, are welded to the upper half of the crank case, the plate 14 being recessed and forming with a plate 27 a casing 17 to accommodate gear for driving a cam shaft 18. An apertured plate 34 is welded to the top of the cylinders to receive the studs 45 holding down the cylinder head, which is welded up from pressings and plates, and a sheet 35 is welded to the plate 34 and to the outer plate 8 of the crank case to form a water jacket. A casing which holds the valve gear is formed between a plate 41 closing the top of the water space in the head and a sheet-metal cover 43 having welded stiffening-ribs 44. After welding has been completed the structures are annealed to relieve stresses.
