Title: Nuclear Fuel Element
IPC: G21C3/33
Filed: 1966-10-13
Abstract: 1,157,979. Fuel elements. COMBUSTION ENG. Inc. 13 Oct., 1966 [2 Dec., 1965], No. 45881/66. Heading G6C. In a nuclear fuel element assembly comprising a plurality of longitudinally extending fuel elements, the fuel elements are secured to a support plate at one end of the assembly by means of spring pins which extend partially into holes in the ends of the fuel elements and partially into holes in the support plate, which latter holes are in alignment with those in the assembled fuel elements. The spring pins may be slotted, tubular pins of C-shaped cross-section, or be spirally shaped. A second support plate is secured to the other end of the fuel elements, extensions on these ends protruding into holes in the support plate which are larger in diameter than the extensions and these are thus free to move upon thermal expansion of the fuel elements. Rods extend between and are bolted to the support plates to hold them in position with respect to each other.

Patent GB-468506-A (GB)
Abstract: 468,506. Calculating - apparatus. WOODS, W. B. (National Cash Register Co.) Jan. 6, 1936, No. 441. [Class 106 (i)] Transfer mechanism.-In a cash register or similar amounting-machine, the driving means for the transfer mechanism of each denomination has at least as many transfer actuating parts as there are denominations in the totalizer. The invention is described as applied to an add-subtract totalizer of the kind disclosed in Specification 368,117. In the known machine, the transfer mechanism is driven by a series of driving members helically arranged on a shaft that makes two revolutions during each operation, the second revolution being necessary to effect transfers consequent upon the addition of the " fugitive one." In the present machine, the second revolution of the shaft is rendered unnecessary by providing each driving member with a number of actuating parts equal to the number of denominations in the totalizer, whereby all initial transfers take place simultaneously during the first step of movement of the shaft and consequential transfers are effected thereafter seriatim. At transfer, a tooth 1a Fig. 3b, on the selected positive or negative totalizer wheel 1, abuts a tooth 23 and rotates a sleeve 25 to the position shown, in known manner. Now, upon the rotation of a driving pinion 31, having as many teeth as there are denominations in the totalizer, the sleeve is rocked through an additional angle by the abutment of the first tooth of the pinion with a lug 78 on the sleeve. A pin 116, Figs. 4a and 4c, projecting from the end of sleeve 25 into a slot 117 in an arm 115 is thus rocked in two steps from the position shown in Fig. 4a to that shown in Fig. 4c. The first step is idle but the second is effective to rock the arm 115 counterclockwise about a shaft 20. A transfer pinion 19 carried by the arm is thus caused to rotate the driving pinion 16 for the next higher denomination through one step in known manner. A single revolution of the pinion 31 is sufficient to effect any subsequent transfer that may occur. The slot 117 is so shaped that, by co-operation with the stud 116 and the shaft 18 of the sleeve 25, it is locked in both positions of adjustment. In order to avoid overloading of the mechanism due to a number of simultaneous transfers, the teeth of the driving pinions 31 for some denominations may be staggered relatively to those for other denominations, additional teeth being provided if necessary for the correct working of the machine.

Title: Ballast circuit for a gaseous discharge lamp
IPC: H05B41/16
Filed: 1974-10-30
Abstract: 1485166 Supply circuits for discharge lamps GENERAL ELECTRIC CO 30 Oct 1974 [2 Nov 1973] 47006/74 Heading H2H In order to avoid large variations in the light output from a fluorescent lamp due to increases in the ambient temperature around the lamp apparatus a capacitive circuit 7 is provided, the capacitance of which decreases with an increase in ambient temperature. The impedance of the circuit 7 thus increases to decrease the power dissipation of the lamp with a resulting decrease in the ambient temperature. The combination of the decrease in lamp power dissipation and decrease in ambient temperature allows the light output of the lamp to remain nearly constant. The circuit 7 may comprise a capacitor 19 in parallel with a capacitor 22 and a thermistor 21 in series. An increase in temperature causes the thermistor 21 to effectively remove the capacitor 22 from the parallel circuit. In alternative embodiments the circuit 7 may include a bimetal switch or a triac controlled by a thermistor for removing the capacitor 22 from circuit. Furthermore the capacitor 22 may be of the kind having capacitance variable with temperature or may be placed in series with the capacitor 19. Lastly the circuit 7 may comprise only a capacitor having capacitance variable with temperature. The lamp apparatus may include two lamps 9, 10, having filamentary electrodes 12, 13, 17, 18 heatable from windings 6, 14, 15 of a transformer 4 having a primary winding 3 and a secondary winding 5. Capacitor 16 is provided for starting purposes and the capacitor 19 will provide power factor correction.

Title: A method of forming rigid structures, and structures formed thereby
IPC: B28B7/34
Filed: 1964-11-18
Abstract: Rigid bodies are formed by thinly coating individual particles of finely powdered material with a thermosetting resin, compacting the material to form a porous body, partially curing the resin at room temperature and then completing the curing in stages at progressively elevated temperatures.  The pores of the body thus formed may be partially or completely filled with a metal e.g. nickel by chemical nickel plating or by an atmosphere of nickel carbonyl.  In one example a porous body of finely divided steel, prepared as above, was sensitized by a three minute dip in a bath containing 400 cc of hydroquinone, 100 cc of Pyrocatechol and 1000 cc of acetone and then activated by a two minute bath of 10 gms of stannous chloride 40 cc hydrochloric acid, and 1000 cc distilled water.  The thus treated body was then placed in a chemical nickel plating bath composed of nickel sulphate (0.08 moles/litre), sodium hypophosphite (0.23 moles/litre), lactic acid (0.3 moles/litre) and propionic acid (0.003 moles/litre) for 16 hours after which the pores were completely filled.  In a second example a porous body of glass was treated as above and then chemically plated with nickel for 20 minutes at 190 DEG F in a bath of 7 ozs of nickel chloride, 1 1/2 ozs sodium hypophosphite, 1 1/2 ozs sodium litrate and 1 gallon of water. This was insufficient to completely fill the pores and this process resulted in a porous body.ALSO:Rigid structures are formed by applying a very thin film of a thermosetting resin to the surface of finely-divided individual glass particles, compacting the particles to form a porous preform, partially using the resin at room temperature and finally completely curing the resin in stages at progressively elevated temperatures. The pores of the body thus formed may be filled with a second thermosetting resin, or may be completely or partially filled with metal (nickel) by a chemical plating process or by an atmosphere of e.g. nickel carbonyl.  In one embodiment a porous mould is made by coating the particles with a thermosetting resin dissolved in a solvent, evaporating the solvent, and manually applying the coated particles to a shaping pattern or mould.  The whole is then enclosed in a flexible impervious bag and further consolidated after which the bag is removed and the resin pre-cured and then cured in stages as stated above.  The mould is preferably composed of strata of powdered material having different sizes the finest being at the operative surface of the mould whilst the coarser particles comprise the body of the mould (see Fig. 5, not shown).ALSO:Individual particles of finely divided powdered material are coated with a thermosetting resin by placing the particles in a cloth bag or the like, immersing the bag in a vessel of resin, which contains a solvent, and ultrasonically vibrating the vessel.  The resin solution is then allowed to drain off the coated particles after which the solvent in the coating is evaporated.

Abstract: 1364873 Dissolving vinyl polymers in water NALCO CHEMICAL CO 12 Oct 1971 [15 Dec 1970 18 Aug 1971] 47534/71 Heading C3P A method for dissolving water-soluble vinyl addition polymers in water comprises preparing a water-in-oil emulsion containing such a polymer in finely divided form, and then adding the emulsion to water to cause inversion of the emulsion, whereby the polymer is rapidly dissolved in the water to form a solution. Polymers specified are polyacrylamide, copolymers of acrylamide with methacrylic acid, acrylic acid, an acrylic acid salt, maleic anhydride, acrylonitrile, styrene or dimethylaminoethyl methacrylate, polyvinyl alcohol, polyacrylic acid, sodium polyacrylate, polystyrene sulphonate, polymers of mono- or di-allylamine, and polymers of dimethylaminoethyl methacrylate. The method is of particular advantage for dissolving polymers having a molecular weight in excess of 1,000,000. The oil component of the emulsion is suitably an aromatic or aliphatic hydrocarbon such as benzene, xylene, toluene, mineral oil, kerosene, naphtha, petrolatum or branchedchain isoparaffinic solvent. The emulsions usually contain an oil-soluble emulsifying agent. Inversion of the emulsion is suitably effected by adding a surfactant to the polymer emulsion or to the water in which the polymer is to be dissolved, before the emulsion and the water are combined; the surfactant may be anionic, cationic or non-ionic. Other usable inversion means include agitation, high voltage electric fileds, heat and pH shift, and addition of elec trolytes to the water.
