IPC: B23K35/30
Filed: 1962-02-12
Abstract: In a gas-welding spheroidal graphite cast iron process, both the iron being welded and the filler rod consist of cast iron, which is wholly ferritic when cast in a sand mould in a section of 10-20 mm., and has the following composition: .C.3.0-4.2%, .Si.2.0-3.0%, .P.less than 0.1%, .Mn.less than 0.1%, .Mg.in such amount, e.g. 0.04-0.08%, that the graphite in the iron being welded and the weld metal is at least predominantly spheroidal, balance being Fe.  To ensure the iron is ferritic under the above conditions it must be free of other carbide-stabilizers, e.g. Cr and Mo.  Specification 874,405 is referred to.

Title: Improvements in and relating to flying machines
IPC: B64C39/00
Filed: 1929-02-18
Abstract: 306,410. Junkers, H. Feb. 17, 1928, [Convention date]. Aeroplanes ; planes, construction of ; cars and cabins.-In a flying machine of the type having hollow wings arranged to accommodate passengers and loads, additional hollow spaces are provided which extend downwardly beneath the wings in such a manner that they are the first portions of the machine to come into contact with the ground in the event of undercarriage breakage thus absorbing the shock and affording protection to the loads carried in the wings ; these spaces are utilized to carry the less valuable inert loads. These protective spaces may extend beyond the leading edge of the wings to take the shock of the machine pitching on its nose. In the construction shown the fuselage is formed with downwardly extending hollow spaces 7 which form the protective space desired; these spaces are continued forwardly to form a nose 8. Further protective spaces are arranged on the leading edge of the wings and serve as housings for the propellers. In the case of a double fuselage machine both fuselages are designed in this manner whilst when there are more than two fuselages all or only some are employed for the formation of protective spaces. Similar spaces may be provided between the leading and trailing edges of the wings to serve as protection ir the event of failure of one side of the undercarriage only. These last-mentioned spaces only are provided on flying machines having no fuselage; in machines with fuselages the fuselages may then also be designed as protective spaces or not.

IPC: C01B17/10
Filed: 1933-02-22
Abstract: Sulphur is melted and the liquid is emulsified by agitation in a liquid having a boiling point above the melting point of sulphur in the presence of a protective material, the emulsion so produced being finally cooled.  The melting point of the sulphur may be reduced by dissolving in it a material such as naphthalene.  The dispersion medium may be glycerine or an aqueous solution of glycerine or of sugar.  As protective material any dispersing or wetting agent or protective colloid may be used; examples are sodium caseinate, glyptal resins, albumen, sulphonated tallow, Turkey red oil, clay, and soaps.

Abstract: 594,283. Annealing bi-metallic products. SUPERIOR STEEL CORPORATION. April 7, 1943, No. 5552. Convention date, Aug. 6, 1942. [Class 72] Bimetallic products having a ferrous metal component and a component of a relatively soft metal such as a copper alloy are annealed by subjecting them to a temperature and for a time indicated by the cross-hatched area on the drawing and then cooling them to at least 900‹ F. at a rate not exceeding the rate of cooling in still air at atmospheric temperature. In the treatment of clad steel bulletcups, the latter are annealed by placing them on an endless belt which carries them through a gas-fired furnace heated to, say, 1200- 1300‹ F. at such a rate that when the belt leaves the furnace the cups have been subjected to the required temperature for the required period. The speed of the belt and the distance the cups travel from the exit end of the furnace is such that when the cups fall off the belt their temperature is at or below 900‹ F.

Title: Protected metal sheets for building purposes
IPC: E04C2/26
Filed: 1949-03-02
Abstract: A coating composition for application over bituminous materials is made by reacting a polymerizable solvent for bituminous materials with a polyester resin formed by reacting a glycol or mixture of glycols with a dicarboxylic acid ester forming material containing at least 10 mol. per cent of one or more unsaturated a ,b -dicarboxylic acid ester forming substances and the balance comprising aromatic and/or saturated aliphatic ester-forming substances.  The polymeriable solvent may be styrene, dichlorostyrene, indene, the coumarone-indene fraction of coal tar distillates, vinyl ketones, vinyl ethers, allyl maleate, allyl phthalate, ethyl acrylate, methyl methacrylate, acrylonitrile or acrolein.  The glycols which may be used to form the polyester resin include ethylene glycol, propylene glycol, triethylene glycol, the polyethylene glycols and unsaturated glycols such as vinyl-ethylene glycol.  The dicarboxylic ester forming substances include dicarboxylic acids, anhydrides, esters and acid-halides, such as maleic acid or anhydride, fumaric acid, citraconic acid or anhydride, itaconic acid, to which substances may be added phthalic acid or anhydride, tetrachlorophthalic anhydride, succinic, adipic, azelaic or sebacic acids.  Monohydric alcohols, e.g. allyl or crotyl alcohol, and/or monocarboxylic acids, e.g. acrylic or crotonic acid may be included as modifiers in the preparation of the polyester resin.  Pigments, fillers and catalysts may be added to the coating composition.  The catalysts may be chain initiating catalysts such as acetyl peroxide, lauryl peroxide, stearyl peroxide, benzoyl peroxide, tertiary butyl perbenzoate, tertiary butyl hydroperoxide, or catalysts to complete polymerization at the surface of the coating where it is in contact with oxygen such as cobalt nitrate or cobalt naphthenate.  The coating may be cured at elevated temperature or by adding cuprous oxide or cuprous salts may polymerize at ordinary temperatures.  In an example, diethylene glycol, maleic anhydride, phthalic anhydride and p-toluenesulphonic acid were reacted together to obtain a liquid polyester which was made into a coating composition with styrene, titanox B 30, chrome oxide green, and cobalt nitrate to which was added benzoyl peroxide as a paste in tricresyl phosphate.

The usual hand-operated slide a, shown in the open position, Fig. 1, has a arm a<2> resting on a rod which is locked against a spring c by a bolt e. The automatic switch, which can be secured to the takeup arm, Figs. 3 and 4, comprising a wheel t adjustably fixed to the spindle r bearing on the film, closes a contact at 13 when the film breaks and operates the electro-magnetic means shown to release the bolt e, the rod band spring c then closing the slide. The electro-magnet j, when excited, moves down the core spindle f against the spring l. The tapered end n engages an incline o', Fig. 8, thereby disengaging the catch o from a recess in the spindle f, the spring m forces the spindle f downwards and the bolt e is released by the incline f<1>. Fixed to the spindle f is an insulated disk i<2> carrying sockets for terminals, (1) preferably in the positive of the motor circuit and (2) in the electro-magnetic circuit so that, when the spindle f descends, the motor circuit is broken and the magnet de-energized. The bolt e may have a spring to disengage it when released. The parts are restored to their operative positions by hand.
