Title: Improvements in or relating to Methods Of and Apparatus For Cooling Granular Materials
IPC: F26B17/10
Filed: 1966-12-22
Abstract: 1,155,060. Cooling granular material. PRAT - DANIEL S.A. 22 Dec., 1966 [23 Dec., 1965], No. 57539/66. Heading F4U. Granular material is passed up a vertical shaft by entrainment in a cooling air stream and after separation from that stream passes down a second vertical shaft in countercurrent flow relationship to a second stream of cooling air which is partly provided by jets directed transversely into the second shaft to promote turbulence. As illustrated, air is withdrawn from the gas outlet 6 of a centrifugal separator 5 to provide the upward flows through the first shaft 1 and the second shaft 7. Valves 10 regulate the amounts of air passing to the bottom of shaft 7 and to transverse jets located at points 9. Granular material to be cooled is introduced at 3 and after cooling falls into a silo 11. Particles which are too heavy to be entrained by the air stream in the shaft 1 fall through a restricted air intake 2, and very light particles are drawn off with the air stream passing through the outlet 6. Air drawn into the shaft 7 may be cooled and/or dried. In a modification, Fig. 4 (not shown), material from the separator is collected in a hopper prior to passage down the second shaft, the residence time in the hopper providing for temperature equalization in the material. A cyclone may be used for the separation, Fig. 5 (not shown), in which case air is withdrawn from the cyclone and from the second shaft immediately below its connection to the cyclone. The granular material may be a fertilizer.

Abstract: 1,237,000. Waveguide ferrite devices. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. 6 Dec., 1968 [8 Dec., 1967], No. 58196/68. Heading H1W. [Also in Division H3] A microwave ferrimagnetic device comprises a slab 3 of ferrimagnetic material having a ground plane 2 on one side and a strip conductor 1 on the other, the slab being magnetized by a field parallel to the ground plane which may vary from zero to a few hundred oersteds. It is stated that such a device has a " cut-off " frequency below which the attenuation remains high and substantially constant and above which it remains low and substantially constant, the two regions being joined by a narrow frequency band within which the attenuation increases rapidly and substantially linearly. The effect of varying an applied field, which may be parallel or normal to the direction of propagation, is to shift the cut-off frequency. For materials of the garnet type, e.g. YIG, the effect occurs in the 1-2 GHz band and for Mn-Mg type ferrites, in the 2-15 GHz band, the field being varied between 0 and 400 oersteds. The device may be used as a dissipative load, variable attenuator, amplitude modulator or high-pass filter. In an example (Fig. 4, not shown), the device is used to terminate one port of a three-port circulator. If the device is operated within the transition band centred around the out-off frequency, it may be used for converting a frequency-modulated to an amplitude-modulated signal.

Abstract: 1371920 Valves SIEMENS AG 23 Dec 1971 [24 Dec 1970] 60094/71 Heading F2V  A valve arrangement 4, Fig. 2, especially for emergency cooling systems for nuclear reactors, comprising an inlet section 3 and two outlet sections 5, 6, has a closure 19 controlled by a piston 17 subjected on opposite sides to the pressures in outlet sections 5, 6 respectively. The arrangement also includes throttles 13, 14, and a duct 18 for equalizing the pressures on opposite sides of the closure 19. An emergency system for a nuclear reactor, Fig. 1 (not shown), includes a h.p. pump 1 for supplying inlet section 3 for subsequent distribution by the valve arrangement 4 to one of two pipe-lines (7, 8) of a low-pressure coolant system incorporating an after cooler (9) and pump (11). In the event of moderate or minor leakage in a main coolant pipe-line of the reactor, the pump (1) is started and supplies the pipe-line (8) via outlet section 6 since the closure 19 normally assumes the position shown due to gravity. However, in the event of leakage from outlet section 6, the consequent pressure drop downstream of throttle 14 creates a pressure differential across piston 17 resulting in lifting the closure 19 against upper seat 21, whereafter delivery is established through outlet section 5 and pipe-line (7). Two such valve arrangements may be connected together to increase safety, one outlet section of the first valve arrangement being connected to one outlet section of the second valve arrangement, and the other outlet section of the first valve arrangement being connected to the inlet section of the second valve arrangement, Figs. 3 and 4 (not shown).

Title: Fast sodium-cooled reactor core structure
IPC: G21C5/10
Filed: 1969-12-15
Abstract: 1,222,930. Reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 15 Dec., 1969 [22 Jan., 1969], No. 60935/69. Heading G6C. A reactor core structure for a liquid metal cooled fast reactor is made up of closely packed hexagonal fuel, blanket and reflector bundles which are held tightly together by an orificing pattern which imposes a higher internal pressure in the outer fuel bundles than in the inner fuel bundles, and which is provided with an hydraulic balancing arrangement whereby a separate unclamping arrangement for refuelling is eliminated. The core is surrounded by structural rings 14 supported by a vessel wall 15 and having their inner surfaces 16 shaped to the contour of the outside surface of the reflector bundles 13. The reflector bundles 13 surround radial blanket bundles 12 and fuel bundles 11. An inlet 17 for the coolant, e.g. sodium, is provided at the lower end of the wall 15. A support plate 18 extends across the bottom of the core and a housing 19 mounted below the plate 18 defines a plenum 20, leakage from which via an aperture 22 goes into the surrounding coolant. The lower ends of the bundles 11, 12, 13 define an inlet plenum 24 to permit coolant to flow horizontally from the inlet 17 to the various parts of the core. This is accomplished by the lower construction of the bundles 11, 12 and that of the bundles 13. In the former, the hexagonal casing extends to the lower extremity of the bundle and the sides of the casing in the region of the plenum 24 are perforated by holes 26. The lower end 25 of the casing is joined to a hexagonal bottom plate 27. In the latter, the casing terminates in the plenum 24 and a bottom plate 27<SP>1</SP> is connected to the upper section of the bundle by a central rod 28. The fuel bundles 11 each comprise a central rod 28<SP>1</SP> joining the bottom plate 27 with a fuel pin support member 29 attached to fuel pins 30. Each blanket bundle 12 is similarly constructed. Each reflector bundle 13 comprises a stainless steel casing penetrated by cooling passages. If desired, the lower ends of bundles 11, 12 can be constructed in a similar manner to those of bundles 13. The central rod 28 or 28<SP>1</SP> resists in tension the upward pressure loading of the fuel pins 30 due to the equal pressures against the bottom plate 27 or 27<SP>1</SP> and the fuel pin support member 29. The bottom plates 27, 27<SP>1</SP> each include a flange 31 to define a space 32 beneath the bottom plate which is vented to plenum 20 via apertures 33 in plate 18. Excessive upward displacement of the bundles is prevented by a rigid hold-down grid 36 located in coolant outlet 21 and normally spaced sufficiently above the bundle handles 35 to permit differential thermal expansion. Structural rigidity in the core during operation is accomplished by orificing the outlets of the outer fuel bundles such that they have a greater internal pressure than the inner bundles.

Abstract: 1299609 Electrically driven cameras NIPPON KOGAKU KK 29 Dec 1969 [28 Dec 1968] 63114/69 Heading G2A A camera in which the film wind and shutter tensioning are effected by an electric motor has a changeover arrangement whereby the camera can take either single shot exposures or a continuous sequence. As shown, the motor M drives a gear train 1, 2, 3, 4, the gear 4 being unitary  with a cam 5 having a flange 5a. A spring 6 biases the cam 5 to the left, but it can slide to the right, against the spring, on a shaft 8. Shaft 8 is integral with a roller 7 and also a bevel gear 8a. Gear 8a engages with another bevel gear 9 mounted on a shaft which has at one end a coupling 10, this coupling engaging with means to wind on the film and wind up the shutter. The shutter is released by a pin 12, which is urged downwards by a spring 13 against a lever 11 whose other end bears against the flange 5a. Fig.1 shows the position just after the shutter has been released, and a switch S 3  has been opened by an operating button 17. The circuit arrangement is such that the motor M is energized, and causes the cam 5 to rotate in the direction of the arrow. At the same time gear 9 is driven to wind on the film and set the shutter. When the winding is completed, rotation of the coupling 10 is stopped by a stop member (not shown), and thus gears 9 and 8a are also stopped. The motor, however, continues to rotate cam 5, which accordingly is caused to slide to the right. Hence a spring- loaded lever 14 which bears against flange 5a is allowed to pivot clockwise and thus changes over a switch S 2 , which stops the motor. The changeover switch S 4  in the full line position closes the contact S, this being the setting for single shot operation. When button 17 is pressed to close switch S 3 , the motor is energized. As cam 5 is rotated it moves to the left, so that lever 11 is pivoted clockwise, so actuating the shutter release pin 12 upwards. At the same time lever 14 is pivoted anti-clockwise so that switch S 2  is changed over, and the motor stops. When button 17 is released, the motor rotates again, and the film and shutter wind are operated as described above. When the changeover switch is moved to the broken line position (C 0 ), and switch S 3  is now closed, the motor continues rotating and performs a continuous series of exposures by repeating the shutter release and winding stages. When button 17 is released the motor stops rotating after the film wind and shutter setting operations are completed. A remote control switch S 5  can be used instead of switch S 3 . A modification of the control circuit Fig.3 (not shown) allows the time between completion of the shutter release and initiation of the winding step to be varied by adjusting a variable resistor.
