Title: Improvements in electromagnetic relays
IPC: H01H51/28
Filed: 1942-07-11
Abstract: 553,329. Electromagnetic switches; contacts. WESTERN ELECTRIC CO., Inc. July 11, 1942, No. 9673. Convention date, July 17, 1941. [Class 38 (v)] In electromagnetic relays having contacts such as 8, 9, 13 carrying films of conducting liquid such as mercury, two or more of the contacts are of appreciable area so that on separation of the two contacts, the film between them is drawn, out and the actual moment of break retarded. Fig. 1 shows a form having two flattened fixed contacts 8, 9 between which moves a flattened contact 13 carried by a cylindrical armature 10 floating in mercury in a fixed guide tube 4 connected to an electrode 5. The members 4, 10 are of materials wettable by mercury and the contact 13 is formed from a doubled length of wire flattened at 13. Mercury is carried by capillary attraction up to the part 13 and thence to the contacts 8, 9. The armature is adapted to be attracted upwards to the pole pieces 2, 3 upon energization of the relay and additional delayed action is provided by means of a small hole 11 in the bottom wall of the armature. The contacts 8, 9 may be sufficiently close together that contact is made between 13 and 8 before the mercury film between 13 and 9 has broken. In modifications, one of the contacts 8, 9 is an unflattened wire so as to provide a quick "break" between it and the contact 13. Specifications 543,008, and 543,935 are referred to.

IPC: C01B31/30
Filed: 1964-03-19
Abstract: High density UC2 particles are prepared by granulating and sintering a mixture of UO2, a binder, and a slight stoichiometric excess of C over that required to form UC, and depositing pyrolytic C on the so-formed granules of UC in a fluidized bed at above 1500 DEG  C. at a rate of deposition less than the rate of reaction of the C with the UC, until the UC is completely converted to UC2.  The granules of UO2 and C may be spheroidized to between 400 and 500 m  diameter before sintering.  The C may be deposited by the decomposition of a hydrocarbon, e.g. CH4, which may be mixed with the fluidizing gas which may be argon.  The particles may have a density of 85-90% theoretical. The product particles may be coated with a first layer of pyrolytic C at below 1500 DEG  C. and a second at above 1500 DEG C., or they may be coated with SiC, or with a double or triple coating of SiC and C.

Abstract: PURPOSE:To realize uniform solder contact so as to improve quality, to reduce man-hours and to improve productivity by deforming the top end edge of the wall on a solder tank side into which a member to be soldered is immersed to an approximately bow shape. CONSTITUTION:Molten solder flows over the top end edge of the wall of a 2nd solder tank 6 on the side facing the lower level side in the conveying direction of a printed circuit board 1 and the circuit board 1 is immersed into the molten solder flowing over said tank. An actuator 7 to deform the side wall surface of the tank 6 corresponding to the lower level side in the conveying direction of the circuit board 1 to the curved surface recessing toward the outside is provided. The front end of the actuating shaft 7a of the actuator 7 is pressed to the side wall surface of the tank 6 via pad 8. The side wall surface of the tank 6 is deformed by expanding the shaft 7a and is released from the deformation by returning the shaft 7a to the home position. The molten solder flowing over the two sides at the top end edge of the side walls of the tank 6 is thereby effectively brought into contact with both ends of the soldering surface of the circuit board 1, by which the quality is improved.

Abstract: PROBLEM TO BE SOLVED: To obtain a wiring board with which a solder bonding operation of high connection reliability is obtained by a method, wherein impurities which obstruct a bonding operation to solder are removed from the region of a nickel- plated film which forms an alloy with the solder. SOLUTION: On an insulating board 4, which contains a copper layer as the uppermost wiring pattern of a multilayer wiring board, the whole face which excludes the external connecting-terminal formation region of a copper layer 3 is coated with a solder-resist insulating layer 2. While the insulating layer 2 is used as a mask, an electroless nickel-plated layer 1 is formed on the exposed copper layer 3. Then, the surface layer part of the nickel-plated layer 1 is etched, and impurities which obstruct a connection to solder are melted and removed selectively. Consequently, a nickel-plated layer 5 not containing the impurities which obstruct the connection to the solder is formed on the surface layer part of the nickel-plated layer 1.  An actual external connecting terminal is constituted, a gold plating operation which ensures the prevention of oxidation, and the wettability of solder is executed to the nickel- plated layer 5 which does not contain the impurities.
