Title: Improvements in or relating to operating mechanism for electric transformer tap changing switches
IPC: H01H9/00
Filed: 1939-02-07
Abstract: 524,485. Actuation of switches. GENERAL ELECTRIC CO., Ltd., and MORRIS, G. G. Feb. 7, 1939, No. 3984. [Class 38 (v)] The main shaft 2 of a transformer tap-changer is operated by a Geneva wheel 1 and striker pin 8 on an arm 6 on a shaft behind, and coaxial with, the motor or hand-driven shaft 20. When the latter is rotated in either direction, a member 21 thereon engages a pin 22 on an arm 11 which is loose on the striker shaft and carries a pair of arms 24, 25, one or other of which, depending on the direction of rotation, engages, after a right angle, a projection 26 on an arm 27 fast on the striker-shaft. Rotation of 11 through 180 degrees stresses a spring 10 by means of levers 12, 13, at which point the pin 8 is about to enter a tooth-slot. Further rotation of 11 allows the spring to expand and advance the wheel 1 one tooth, but the action is retarded by the dashpot action of the piston 16 in the cylinder 14, the retardation being adjustable by valve 19. The arrangement also incorporates that of Specification 524,456.

Abstract: 1419659 Imaging lithographic plates electrophotographically RICOH K K 26 Jan 1973 [8 Feb 1972] 4022/73 Headings G2C and G2H A photo-conductive lithographic plate blank is charged, exposed and developed with a liquid developer, then subjected to a corona discharge and etched, adhesion of the etching liquid to image areas not charged by the corona discharge being prevented by incorporation or coating of a surface-modifying agent in or on a photoconductive material which would otherwise be wetted by the etching liquid. The surfacemodifying agent may be mixed with the photoconductive material or may be applied to the surface of a formed photo-conductive layer. Suitable surface-modifying agents are silicone oils, paraffin, linseed oil, mineral oil, dialkylnaphthalenes and monoalkyldiphenyls. Preferably the blank consists of a support such as paper which has been made electrically conductive by coating one side of the paper with a layer containing a conductive polymer and clay and then coated on the other side with a layer of casein, epoxy resin, styrene/butadiene copolymer and clay and overcoated with a layer of ZnO, acrylic resin, silicone resin and silicone oil.

Abstract: 985,574. Cooling shaft furnace walls. GLAVERBEL. Feb. 2, 1962 [Feb. 17, 1961], No. 4197/62. Heading F4B. In a shaft furnace down which vitrifiable raw material falls in scattered form to be preheated by fumes rising from a melting zone at the bottom, waste heat is recovered from the preheater part of the shaft by the circulation of cooling fluid in metallic elements arranged against the wall of the shaft and through further metallic elements within the upper part. Hollow metallic sectors 11 fit closely against the trued outer face of the preheater shaft 4, the inlet pipes 12 and outlet pipes 13 of the sectors being connected through ring pipes 14, 15 to headers 16, 18 respectively.

Title: Device and method for the display of local disorientations in  single crystals
IPC: G01N23/205
Filed: 1972-01-31
Abstract: 1350049 X-ray diffraction apparatus COMMISSARIAT A L'ENERGIE ATOMIQUE 31 Jan 1972 [3 Feb 1971] 4338/72 Heading H5R In an X-ray arrangement for the display of local defects in single crystals, applicable to crystals having a thickness up to several centimeters, the crystal is irradiated by a monochromatic X-ray beam having at the crystal a size comparable to the defects to be displayed; the crystal is moved, while under irradiation, in a direction perpendicular to that of the incident X-ray beam; and the diffracted beam selected by a stationary slit is received by a detector. With the apparatus shown, the presence of defects in the crystal 11 to be examined is first tested for by mounting the crystal on a carriage 22 which is traversed across the beam, upwardly in the arrangement shown, while the diffracted beam which passes through the slit 13 is received on the film 27; if the crystal were perfect, a single straightline would be formed on the film, but this is broadened due to changes in the diffraction angle produced by defects. If defects are detected, they are displayed by removing the film holder 27, adjusting the slit 15 to have a width not exceeding that of the diffracted beam from a perfect crystal, and arranging for the film 14 to be moved parallel to the movement of the crystal, but preferably opposite in sense, at a speed related to that of the crystal in the ratio of their respective distances from the X-ray source, whereby defects irradiated by the beam at a given position of the crystal are recorded, on a magnified scale, by a reduction in density of the image at the corresponding position on the film 14, due to the diffracted beam partly missing the slit 15. It is stated that the 3-dimensional position of the defective regions in the crystal may be determined by repeating the procedure several times using different reflections. Positioning of the slit 15, which is in the form of a slotted cylinder 32 mounted along a diameter of a disc 16, is effected by displacing the disc with the screw 33 and rotating it with a pinion meshing at 29 with teeth on the circumference of the disc, while the effective width is adjusted by rotating the cylinder with the screw 34.

Abstract: 1,093,541. Indoor games. YISSUM RESEARCH DEVELOPMENT CO. Nov. 12, 1965 [Feb. 1, 1965], No. 4376/65. Heading A6H. [Also in Division G5] A game intended to promote a knowledge of chemistry comprises a board divided into spaces, some of which carry symbols of chemical elements, and a number of pieces corresponding to the elements. Using means operated by chance, the players in turn eventually select a number of elements and then seek to combine them into molecules or even to compose chemical equations. To vary the game, the spaces on the board which do not carry chemical symbols carry order cards, e.g. "miss one turn", and a system of monetary rewards and penalties may be devised. Fig. 1 shows a design of board based on the Periodic System of classification of the elements, the spaces a-p carrying order cards. As shown in Fig. 12, the means for indicating the space to which a piece is to be moved may comprise two dials A and B or A and C, the dial A indicating the period in the Periodic System and the dial B or C indicating the position in that period. The pieces are preferably designed so as to distinguish metals from non-metals and to facilitate the formation of molecules by joining suitable atoms, Fig. 13<SP>A</SP> shows a suitable arrangement, but others are described also (Figs. 14 and 15, not shown). The game may include supplementary boards (one for each player) on which the selected atoms may be temporarily stored.

Abstract: 841,650. Fluid heaters. PETRO-CHEM PROCESS CO. Inc. Feb. 11, 1958 [Feb. 27, 1957], No. 4407/58. Class 64(1) In a heater for oil and like fluid in which the wall of an upright cylindrical combustion chamber 12 closed at its upper end is lined with tubes 21 carrying the fluid to be heated, one or more burners 21 are located at the bottom of the combustion chamber, the tubes 21 being exposed to radiant heat from burner gases forced upwardly near the axis of the combustion chamber and then to convection heating by the now relatively cool gases as, deflected by guide means at the top of the chamber they pass downwardly over the tubes to an annular exit 35 from the combustion chamber located at the lower end thereof. In the form shown the change of direction of the gases at the top of the combustion chamber is effected by a conical baffle 19 which also heats the tubes 21 by radiation. The combustion gases pass from the exit 35 to a manifold 38 and thence through a duct 39 to the stack 11. Combustion air forced by a blower 30 to the burners 27 may be preheated in a heat exchanger 31 by the exhaust gases passing through the duct 39. The inner wall of the manifold 38 comprises a ring 36 and in a further form described the lower portion of each tube 21 is finned and the ring 36 is extended upwardly so that the finned portions of the tubes are disposed within the manifold 38. An additional blower may be provided in the exhaust gas outlet duct 39.
