Patent JP-S5697116-A (JP)
Title: Voltage stabilizing circuit
Inventor: KINKO AKIRA
IPC: G05F1/56
Filed: 1980-01-07
Abstract: PURPOSE: To stabilize the voltage, by connecting a resistor and a capacitor in parallel between the output terminal of a voltage stabilizing circuit and the input terminal of an error voltage detection amplifier, tying the input terminal of the error voltage detection amplifier and the output terminal of the reference voltage source with a resistor, grounding the input terminal of amplifier with a capacitor, and selecting the ratio of capacitors as specified.  
     CONSTITUTION: In a conventional series stabilizing power supply circuit, a capacitor Cf6 is provided between the output terminal 2 and the input terminal of the amplifier 3 to improve the counter-measure for conventional oscillation and the transient characteristics. Since the transient voltage from the outout terminal 2 is a differentiated waveform and it is transmitted to the amplfier 3 via the capacitor Cf6, if the transient voltage is more than the withstanding input voltage of the amplifier, the amplifier is destroyed. Then, the capacitor Ci11 is provided between the  input terminal and ground of the amplifier 3. Taking the output voltage maximum  value as E omax , amplifier withstanding input voltage as Eb, when selection is made  as Cf/Ci<Eb/E omax , then the output voltage is divided into Cf and Ci, consequently, the amplifier 3 is not destroyed.

Title: Improvements in or relating to nuclear power plant utilising steam
Inventor: BAUER STEFAN GEORGE
IPC: G21C15/18
Filed: 1961-01-02
Abstract: 928,484. Nuclear power plant. ROLLSROYCE Ltd. Jan. 2, 1962 [Jan. 2, 1961], No. 145/61. Class 39 (4). A nuclear power plant has its steam-handling components distributed between at least two compartments separated by a steam condenser, which is in free flow connection between the compartments, so that on failure of a component in any compartment steam will be condensed on flowing through the condenser. The object of the invention is to reduce pressure in the compartment by condensing substantially the whole of the steam passing through the condenser. In Fig. 1 the reactor 12, used in a marine vessel, is housed within the compartment 11, and in the event of accident the steam is led from the compartment 11 through a series of apertures 18 in the bulkhead 15 to the condenser 14. Any remaining air is passed to the engine room 13 through the apertures 19 in the bulkhead 16. The steam trap condenser comprises a large number of corrugated metal plates e.g. aluminium arranged in a stack, each plate having its edge to the steam flow and its corrugations inclined to the flow, for example at 45 degrees. The corrugations of adjacent plates are inclined to each other, for example at right angles, and the plates are maintained at a temperature near the ambient temperature of the compartment 17 in which they are housed by the normal compartment ventilation arrangements.

Title: Improvements in thermionic valves
IPC: H01J19/42
Filed: 1938-01-04
Abstract: 508,853. Welding thermionic valves. ROBINSON, E. Y., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Jan. 4, 1938, No. 257. [Classes 83. (ii) and 83 (iv)] [Also in Group XL] Anodes, enclosing screens, shields, &c. of a thermionic valve are secured to their support wires or posts by forming in a tubular anode &c. one or more longitudinal grooves to accommodate the support wires &c., an aperture being formed on one or each side of the groove for the insertion of a spot welding electrode so that the anode &c. may be welded to the wires. The insertion of a welding electrode in the axial direction within the anode is thus avoided and a valve of smaller size for a given electrode dimension may thus be built or an envelope of given size may accommodate a larger electrode or other component. In a pentode valve having a flattened tubular sheet metal anode 4, support wires 3 and lead wires carried by the seal 2, back bones 5, 6, 7 for control screening and suppression grids secured in main cross pieces 8, 9 and a filament cathode 12 supported by springs 11 from a mica cross piece 10 having a closed tubular rivet at each end, the anode, which is preferably formed from a single bent sheet provided with a lock seam, has at the two ends of the major axis inwardly directed longitudinal grooves 13 to receive the support wires.3. At each side of the groove, preferably at the locations shown, slots 14 are cut to accommodate the welding electrodes 16. Some of the metal removed from the slots is retained to form a welding tag or tongue 17, at one or both sides of the grooves in order to facilitate welding. In a modification a slot and tag may be formed at one side of the groove only so that one welding electrode may be inserted laterally as shown in Fig. 5. In a further form the groove may be convex outwards, Fig. 6, in which case tags are dispensed with. In another form only one pair of slots may be provided at each support wire and a double weld effected therein.

Abstract: 983,212. Distillation of water. COW & GATE Ltd. Jan. 3, 1963 [Jan. 3, 1962], No. 295/62. Heading B1B. Fresh water is obtained from an aqueous salt solution, e.g. sea water, by supplying the solution to a series of annular trays 23, Fig. 1, or to a series of annular discs 50, Fig. 2, made of porous material, while hot air is passed over the trays or discs whereby water is evaporated from the solution, and leading the moistureladen air into contact with a surface, which is cooled by some of the salt solution, so that the moisture-laden air is cooled and the watervapour condensed to yield the required fresh water. In Fig. 1, the salt solution is introduced into tank 26 through pipe 27. Some of the solution flows through pipes 30 and 33 on to plate 34 which distributes the solution on to the top tray 23, from which it drips down through holes 24 on to the next tray. Some of the solution in tank 26 overflows through pipe 28 into jacket 15, where it functions as cooling- liquid for the condenser-surface 11. Air is introduced into the apparatus through tube 20; the air is heated by heat-exchangers 18, mounted in duct 13, and the hot air flows up over the solution which it is flowing down from tray to tray. Water-vapour is condensed out of the air on the bottom of tank 26 and on the inner wall of tube 11; and the distilled water, which collects in vessel 17, is withdrawn through pipe 42. Concentrated salt solution collects in vessel 39, and is drained off through pipe 40. The cooled air is recirculated to the heat-exchangers 18 through openings 21. The heat-exchangers may consist of an expansion chamber in the exhaust system of an internal combustion engine. A fan may be used to increase the circulation of the air. The salt solution may be continuously circulated through jacket 15. Cooling may also be assisted by the provision of gilled tubes or fins on the inner surface of tube 11. In Fig. 2, the porous discs 50 are mounted on pipes 51; and there are small holes 53 drilled in each pipe 51 to form communicating passages to the porous discs. The salt solution flows from tray 56 to the pipes 51, and thence to the discs. The discs become saturated with salt solution, and excess solution drips down into tray 54. The discs may be made of felt, supported on wire-mesh.

Abstract: 450,213. Plug-and-socket couplings. ALLDAY, N., The Nest, Streetly Lane, Four Oaks, and BAIN, R., 25, Beaudesert Road, Handsworth, Birmingham, both in Warwickshire. Jan. 4, 1935, No. 309. [Class 38 (i)] In a plug-and-socket coupling having a closure member for closing the sockets when the plug is withdrawn, the closure member is rotatably mounted for movement in a helical path and is acted upon by a spring to move it to the closed position. The cover 8 of the casing of the socket member is formed with bosses 12 carrying a bridge piece 14 in which is mounted a metal collar 15 formed internally with a screw thread of quick pitch. A closure disc 16, having a stud 18 threaded to engage the collar 15, is normally held against the openings 9 by a spring 20. When the pins 10 of the plug member are inserted through the openings, the closure disc is pushed back against the action of the spring and simultaneously rotated to bring holes 19 into alignment with the holes 9, when the pins can pass through into the sockets. The face of the disc 16 may be recessed at 21, Fig. 4, to form a lead for the ends of the pins. In a modification, the screw is carried by the bridge and the collar 15 is mounted on the disc. In another form, Fig. 5, the screw 18 is mounted on the cover 8 and the spring is retained between the collar 15 in the disc and a washer 23. In a modification, the closure member is in the form of a rectangle of such proportions that in one position the holes in the cover are closed and are uncovered in another position.

Abstract: 1,271,061. Self-skinned polymer foams. UPJOHN CO. 5 Jan., 1970 [10 Feb., 1969], No. 463/70. Headings C3C and C3R. Cellular polymer articles having an integrally formed non-cellular skin are formed by moulding a polymer foam forming reaction mixture in a closed mould, of a volume less than that which would be occupied by the resultant foam if the said mixture were allowed to rise freely, a catalyst system being chosen such that the interval between cream time and final rise time of the foam is not more than 33 seconds. Suitable foams may be composed of polyurethanes, polyureas, polyimides, polyamides, polyoxazolidinones and polyisocyanurates. Catalysts capable of providing suitable time intervals may be chosen by trial and error from conventional catalysts, or the required effect may be obtained by using excess quantities of conventional catalysts. Thus, polyurethane catalysts may be employed in amounts varying from 0À1 to 2À0% by weight of the total reactants. Preferred polyurethane catalysts are tertiary amines such as triethylene diamine and dimethylethanolamine, and organic derivatives of tin such as stannous octoate, dibutyl tin dilaurate and dibutyl tin diacetate. Mixtures of such tin and tertiary amine catalysts are particularly preferred. Preferred polyisocyanurate catalysts are tertiary amines such as N,N<SP>1</SP>,N<SP>11</SP>-tris (dialkylaminoalkyl) hexahydrotriazines, N.N-dialkylethanolamines and triethylene diamine in admixture with monomeric homocyclic polyepoxides such as novolac resin glycidyl ethers and glycidyl ethers of non-fused polynuclear phenols. In a preferred aspect of the invention the components of the foam forming reaction mixture are cooled to a temperature of between 0‹ C. to 15‹ C. before being brought together. Examples describe the preparation of integrally skinned rigid foams composed of polyurethanes and polyisocyanurates. Uses.-Upholstery, automobile bodies and padding, furniture construction, walls, partitions and table tops.
