Title: Improvements in or relating to nuclear reactors
IPC: G21C1/00
Filed: 1964-10-21
Abstract: 1,070,835. Controlling reactors. GENERAL DYNAMICS CORPORATION. Oct. 21, 1964 [Oct. 31, 1963], No. 42906/64. Heading G6C. In a high temperature, helium gas cooled, graphite moderated nuclear reactor, a prompt negative temperature coefficient of reactivity is provided by the mixture of fertile and fuel materials in the fuel elements. In addition, an absorber material having a non-1/v characteristic, i.e. the thermal neutron absorption increases with temperature, is distributed through the core being concentrated at the hottest zones. The loading of the core is such as to produce a flat flux profile. A burnable poison is placed along the fuel element spines. The non-1/v absorbers are rhodium-103, erbium- 167 and plutonium-240 and the fertile material, PU-240, acts as a resonance absorber, with a prompt response to temperature changes due to the Doppler action. The heated helium is pumped into a steam generator coupled to the turbine of a power plant.

Abstract: 1,161,257. Pocket soap dispenser. A. BELZ. 21 Sept., 1967 [29 Sept., 1966], No. 43032/67. Headings A4C and A4V. A pocket soap dispenser for accommodating a square section cake of soap 11 comprises a housing 1 made of plastics material and of square section which carries a closure member 2 at its upper end. This closure member carries a magnet 3 and a square section recess 4 which opens inwardly and receives a flat spring 5 bent into a loop, the horizontal ends of which are secured by means of screws 6. The spring has a square recess 7 at its highest point through which is mounted a bulbous head 8 of a spindle 10 provided with a thread 9. The spindle receives a square section cake of soap 11 and carries a frame 13 at its lower end 12 which is adapted to form a hand wheel to receive a plate shaped rasp 19. The frame 13 is of square cross-section and provided with two vertical intersecting butt-jointed ribs 15, 16 in the intersection of which is located a boss 17 adapted to receive the offset end 12 of the spindle and is conected to the frame by means of a split-pin 18. The frame projects beyond the housing past surfaces of ribs 15 and 16 to such an extent that its upper edges are flush therewith after insertion of the rasp wheel 19. The soap 11 thus protrudes slightly beyond the lower edge of the housing 1 permitting its removal from the cake by scraping, i.e. rotating the housing to engage the rasp on the base of the cake.

Title: Process for relieving stresses in metals
IPC: C22F3/00
Filed: 1962-11-15
Abstract: 990,404. Altering physical properties. E. I. DU PONT DE NEMOURS & CO. Nov. 15, 1962 [Feb. 5, 1962], No. 43239/62. Heading B3V. A process for relieving stresses in a metal object comprises positioning the object in spaced relationship to a layer of a detonating explosive with a shock wave transfer medium between them and initiating said explosion. In an example a 2 inches thick aluminium plate 1 having residual stresses of 15,000 p.s.i. is positioned in the bottom of a wooden vessel 4 which is filled with a transfer medium, e.g. water, until the plate is covered to a depth of 1 inch and a sheet 2 of P.E.T.N. explosive in a 50/50 mixture of butyl rubber and thermoplastic terpene resin having an explosive load of 2 grams/ins.<SP>2</SP> and a detonating velocity of 7000 meters/sec. is positioned by pieces of wood above the plate and water layers such that the edges of the plate and explosive are in alignment. The charge is fired by an electric blasting cap via a 6 ins. equilateral triangular line wave generator 8 taped to the shorter edge of the sheet. The residual stresses were reduced to 100 p.s.i. with a reduction in plate thickness of 0.7%. In a second example a variable section flanged aluminium forging, Fig. 4, is similarly treated using a P.E.T.N. explosive layer comprising P.E.T.N. 35%, red lead 50%, in a 15% binder of 50% butyl rubber and 50% of a terpene resin and having an explosive load of 2 grams/ins.<SP>2</SP> and a detonating velocity of 5000 meters/sec. The gap between the flanges furthest away from the explosive are lined with aluminium foil and filled with steel, lead or Wood's alloy 10 prior to stress relieving and subsequently removed. A cylindrical bar surrounded by a transfer medium and a cylindrical explosive charge is similarly treated to effect stress relieving. Metals such as steel, copper, aluminium, lead, magnesium, nickel, tin and zinc and alloys thereof may be used (list given). The explosives which may be formed into a shape complementary to that of the workpiece may be of the nitroglycerin, amatol (T.N.T.-ammonium nitrate mixture), cyclotol (T.N.T.-RDX mixture) or P.E.T.N. types having loadings of 2-4 grams/ins.<SP>2</SP> for metal of 3 ins. thickness and an explosive reaction rate in excess of the velocity of sound or at least 1200 meters/sec.

Abstract: 1279660 Charge and discharge systems for batteries WOODBRO CORP 4 Sept 1969 [12 Dec 1968] 43915/69 Heading H2H A charging system for a battery 140 comprises a voltage regulator 110 controlled by a transistor 116 receiving a reference voltage from member 118 and the battery terminal voltage from potentiometer 120, the arrangement being such that the regulator output voltage increases with the terminal voltage (as charging proceeds) until a predetermined terminal voltage is reached, whereupon a diode 111 is reverse biased by the voltage across a resistor 117 to interrupt the charging current and alter the output signal from transistor 116, which alteration abruptly reduces the regulator voltage to below that of the battery. The battery then slowly discharges through members 117, 118, 120, 122 until the diode 111 is no longer reverse biased, whereupon the output voltage of the regulator is abruptly increased and charging of the battery recommences. An indicator lamp 112 enables the charge and discharge periods to be detected and the state of charge and capacity of the battery to be deduced. It also indicates the presence of the supply to the regulator and of the battery in the circuit. It may be replaced by an alarm triggered by a voltage-sensitive circuit. During the slow discharge of the battery the signal from transistor 116 slowly increases the output voltage of the regulator.

Abstract: 1,028,333. Supercharged I.C. engines; gas turbine plant. SCHWITZER CORPORATION. Nov. 22, 1962 [March 1, 1962], No. 44190/62. Headings FIB, FIG and FIT. In a control system for a turbocharged I.C. engine in which pressurized lubricant is supplied to bearings 64, a valve member 32 is held off a seat 31 in the turbine waste gate until the lubricant pressure is sufficient to overcome the valve biasing means 52. In operation valve 32 is in its solid line position until the engine is started so that initially part of the engine exhaust gases are diverted from manifold 23 through passages 28, 26, to atmosphere thereby limiting the turbine/compressor speed. With increasing speed the engine oil is delivered through line 63 to bearings 64 and at a predetermined pressure the force on piston 48 overcomes the spring 52 and thereby moves valve member 32 against seat 31. All exhaust gas then passes through the turbine which accelerates to its normal speed. If boost pressure in passage 27 becomes too high valve member 59 is moved against spring 61 to open passage 57 thereby allowing compressed air to fill the housing 34 to the left of piston 48. This pressure causes movement of piston 48 against the oil pressure thereby unseating valve member 32 causing exhaust gas to by-pass the turbine and a consequent reduction in boost pressure to a predetermined level. The compressed air in housing 34 passes to atmosphere through metering orifice 56 thereby maintaining a constant pressure level in housing 34 and hence an equilibrium position of the valve member 32. In the event of failure of valve 58 the pressure acting on the upstream face of valve member 32 unseats it at a predetermined boost pressure. A vent 53 serves to discharge any oil leaks into the area between piston sealing rings 49, Fig. 3 (not shown). If the oil pressure rises above a predetermined value, valve member 71 is moved to open passage 68 thereby discharging oil through line 68 to sump 67.

[Also in Division G1] An apparatus for positioning a tool or tool carrier 1 such as a flame cutter or a photoelectric line tracer from a workpiece 6 comprises a contact member 10 to locate the tool or carrier 1 at a desired spacing from the workpiece 6, the tool or carrier 1. being movable between spaced limit positions relative to a support 11 which is driven in the appropriate direction as the tool or carrier 1 reaches one or other limit position. as the contact member 10 rides over the workpiece 6. Small undulations in the plate surface 6 are compensated for by a bellows coupling 13 between the carrier 1 carrying cutting nozzles 3, 4, 5 and a member 15 rotated by a servomotor system (not shown) of a gas distributer 11. As the roller 10 traverses a peak, the carrier 1 and a push-rod 26 are raised whilst the bellows 13 is compressed. When the upper limit position is reached which is a small distance, e.g. <SP>3</SP>/ 16  inch, before the bellows 13 is fully compressed, the rising push-rod 26 pivots a lever 29 to cause a micro-switch 36 to be actuated by a screw 33. A motor 40 is thereby energized to rotate through gears 41, 42 a spindle 43 which raises a support frame 20 and the attached gas distributer 11 and tool carrier 1. As the frame 20 is raised by the motor 40, the push-rod 26 moves down and the motor 40 stops when the screw 33 is lifted off the switch 36. Upon the roller 10 encountering a depression in the plate 6, the carrier 1 is moved downwards and when the lower limit position is reached, e.g. <SP>1</SP>/ 16  inch, before the bellows 13 is fully extended, a microswitch 37 is actuated by a screw 34 to cause the motor 40 to drive the carrier 1 downwards until the screw 34 disengages the switch 37. Before the end of the cut, a lock switch (122) (Fig. 2, not shown) is actuated to prevent the cutting head 1 dropping when the plate edge is met. The cutting head 1 is returned to its initial position by actuating a switch (117) causing the frame 20 to be raised until an upper limit switch (115) is opened. The plate 6 may be cut by a plasma flame.
