Title: Rotary boiler
IPC: F28D11/04
Filed: 1971-04-19
Abstract: 1331563 Rotary boiler E I DU PONT DE NEMOURS & CO 19 April 1971 [18 Feb 1970] 21976/71 Heading F4A A rotary boiler comprises a boiler chamber B defined by a casing 1 mounted for rotation about its axis, and a cylindrical liquid supply chamber 11 rotated therewith by a motor M and supplied through tubular shaft 6 with liquid which then flows to the boiler chamber B through conduits 21, and further conduits 22 which serve to maintain the annular depth of liquid in the boiler chamber at a desired predetermined level. The conduits 21 and 22 are equally spaced around the circumference of casing 1, and the conduits 22 terminate at a distance from the casing equal to the said predetermined level, (and may be adjustable to vary that level), so that if the liquid level falls vapour under pressure in the boiler chamber enters the chamber 11 and forces more liquid into the chamber B through the conduits 21. The boiler is heated by means of a surrounding combustion chamber C in which is burned fuel from a nozzle (30), Fig. 2 (not shown) with air from a manifold (34), and the outer wall of the boiler casing may be provided with ribs 29 to increase heat transfer. The vapour so produced passes to a vapour chamber V internally of the boiler chamber and thence leaves through tubular shaft 5. The chamber 11 is provided with radial vanes 19a to impart rotational energy to entering liquid, and the chamber V with radial vanes 13a to recover rotational energy from departing vapour. In a modification, Fig. 6, boiler chamber B<SP>1</SP> is defined by a number of toroidal sections 56 externally of casing 50 of liquid supply chamber 59 and communicating therewith by conduits 61 and 63, analogous to conduits 21 and 22 of Fig. 1, and with vapour chamber V<SP>1</SP> through conduits 62.

Abstract: 316,579. Westinghouse Lamp Co., (Assignees of Slack, C. M.). July 31, 1928, [Convention date]. R÷ntgen-ray tubes; vacuum tubes.-In order to produce X-rays of high frequency or highvelocity cathode rays, X-rays are caused to impinge on a cathode liberating secondary electrons, the velocity of which is increased by the difference of potential between this cathode and a secondary target on which they impinge. Fig. 1 shows the invention applied to an X-ray tube. From the cathode 2, consisting of a coil of tungsten or tantalum mounted in a focussing cup 8 and electro-static shield 9, electrons are emitted to strike a disc of tungsten &c. mounted in a copper block 10, which also forms the anode, and inclined to direct the X-rays generated against a second cathode 16 connected to the cathode 2 and shaped to focus the electrons emitted on to a secondary target 18 mounted in the block 10. In a modification the secondary cathode is considerably larger than the primary cathode and surrounds it, only one target being employed. Fig. 3 shows an arrangement for generating high-velocity cathode rays. In addition to primary and secondary cathodes 23 and 24 arranged as shown in Fig. 1 a tertiary cathode 25 is provided which directs the liberated electrons through a tubular anode 27 to a thin glass window 30 in the tube.

Abstract: 615,366. Stencilling apparatus. ABBEY, A. (Handels-och Fabriksbolaget Hjalmar Andren). July 31, 1946, No. 22859. [Class 100(ii)] In a stencil printing machine a carriage 3, displaceable along a fabric supporting table 1, carries a coiled stencil 16 and a colour container 17, the colour being applied to the fabric by an endless web bearing against the stencil 16 and advancing over the stencil during the movement of the carriage. The web passes round rollers 6, 7 and one or more intermediate rollers 15, each roller being journalled in vertical slots in the carriage 3. Raised fillets on the edges of the web prevent the colour from falling over the edges of the stencil. The web may be provided with an internal surface covering of leather or other impermeable material. The rollers 6, 7 may be driven positively, or by the friction on the stencil, slippage occurring causing the colour to be rubbed through the stencil, the slippage being ensured if desired by brakes on the rollers. The return movement causes further penetration and a scraper consisting of a felt pad 29 removes surplus colour, and a similar device may be fitted between the guide roller 30 and the rod 20 to clean the stencil before coiling.

Abstract: 963, 578. Nuclear reactors. SIEMENSSCHUCKERTWERKE A.G. June 10, 1963 [June 9, 1962], No. 23119/63. Heading G6C. Corrosion and fission products are removed from the fuel solution of a homogeneous nuclear reactor by deposition on the walls of the circuit which are at the highest temperature in relation to the fuel solution, the deposition region lying outside the reactor and the increased wall temperature being produced by nuclear or chemical reactions and by thermal insulation. The wall of the deposition region may contain material having high gamma ray absorption, to produce the required heating, and may also contain fissile material; in addition the wall may include a catalyst for recombining radiolytically formed substances, such as oxygen and hydrogen, so producing heat by chemical reactions. In Fig. 1 a fissile solution flows from the reactor vessel 1 through the duct 3, where deposition is to occur, to heat exchanger 7, pump 8, and back to the reactor. The duct 3 is surrounded by thermal insulation 4, which may be of quartz foam, and extends between two flanges 5 and 6 so that the duct can be replaced. A tube of canned fissile material may be inserted inside the duct 3. In a modification, Fig. 2, the duct 3 is divided by partitions 31-33 containing fissile material and is surrounded by a reflector layer 9, for example of zirconium hydride, and of thermal insulation 4. Catalysts may be provided in the form of ribs on the partition.
