Title: Improved method of preparing a sand-core for foundry-use
IPC: B22C1/24
Filed: 1948-02-12
Abstract: A core is made from sand, drying oil and an accelerator including a substance containing the peroxide group, the proportions being such that an adequate bond is formed on setting, but this does not occur before moulding is finished.  Suitable oils are tung, oiticica, dehydrated castor, linseed, perilla, sunflower seed, grapeseed, soya and tall.  They may be blown with air, heat polymerized, bodied, vulcanized or isomerized.  The peroxide compound may be inorganic, e.g. peroxides of hydrogen, sodium, barium or zinc or alkali perborates, percarbonates or persulphates, or organic, e.g. alkyl-derivatives of hydrogen peroxide, e.g. ethyl peroxide and benzoyl peroxide.  The peroxide compound may be mixed with the oil before use or be sprayed on to the oil bonded body.  The usual metallic dryers may be added also. Some examples of suitable mixtures are given.  The Specification as open to inspection under Sect. 91 comprises also the application of the mixtures of oil and accelerator to the making of protective coatings, impregnated paper or textiles, laminated stock and sheet such as linoleum or oil cloth.  This subject-matter does not appear in the Specification as accepted.

Testing edge of coins for milling.-In a coinfreed machine the coin shoot, comprising a fixed: wall 11, Fig. 3, and hinged wall 12, has a width substantially equal to the diameter of the, coin- 19 which runs on a ledge 13 on the wall 12. Thewall 12 carries a clamp 16 for a needle 17 the point of which projects above the ledge 13 a. a. distance equal to the depth of the milling. The needle point 17 engages the grooves in the milled edge of a coin of proper diameter and allows it to pass but stops a smooth-edged coin.. To clear and return an arrested coin, the wall 12 is moved against the action of a spring by mechanism connected to a lug 21 thereon and a portion 22 of an ejector 23 causes the coin to, fall through an opening 24 to a return shoot. Instead of a needle point, a hardened knife edge or a strip of material may be used. A wheel 25 with ratchet teeth, as shown in Fig. 5, may be employed. In a modification, Fig. 6, a gearwheel 26 to mesh with the milled edge is used at the top edge of the shoot and a needle point P at the bottom edge.

Abstract: 138,930. Durio, E. Feb. 13, 1919, [Convention date]. Stretching by tension.-In stretching tanned skins, an equal tension is applied over the whole surface by means of a number of independently movable gripping elements comprising pivoted jaws 4 connected by links 7 to rods 6, so that the grip of the jaws increases with the tension on the rod. At one end of the frame, the rods 6 are connected to piston heads in cylinders 11 actuated by fluid pressure from a common supply pipe 15, the pressure thus being evenly distributed. At the other end of the frame, the pull on the grippers is taken by adjustable springs 8 encircling the rods 6 and abutting against stationary supports 10 which may be pivoted about vertical ones. The cylinders 11 are mounted to swing about pivot pins 12 adjustable in a transverse slot 13 in the frame, being clamped by nuts 14 if necessary. A diametrically opposite set of pivots may be carried by a slotted bar arranged above the cylinders. The supports 10 may be transversely adjustable.

The alkyds may be derived from maleic, fumaric, itaconic, citraconic and mesaconic acids and polyhydric alcohols of which many are listed including ethers of one or two molecules of allyl or methallyl alcohol with one molecule of a polyhydroxy compound.  The alkyds may also be modified, if desired, with the usual ingredients.  The liquid monomers specified are styrene and various methyl derivatives, isopropenyl toluene, vinyl naphthalene, vinyl benzoate, vinyl dibenzofuran, acrylonitrile, methyl acrylate and methacrylate, isobutyl methacrylate, methacrolein, allyl lactate, itaconic acid, diallyl phthalate, diallyl phenyl phosphonate, carbonyl bis-(allyl lactate) and many other compounds simple and complex, of the ester type.  The polymers (including partial polymers) described are polymethyl acrylate and methacrylate, polystyrene, polydiallyl phthalate and polydiallyl phenyl phosphonate.  The fillers which may be used are organic, inorganic or combinations thereof and specified are (1) fibrous such as glass, various silicates and cellulose (alpha cellulose, paper, cloth, cotton or wood); and (2) non-fibrous such as ground glass and kaolin (which may be the dehydrated form). The kaolin, cellulose or silicate fibre may, if desired, be resin coated, i.e. coated with a thermosetting reaction product of formaldehyde and a heterocyclic polyamine, many of which are specified.  The products obtained are further improved if the composition contains a base of a metal of Group II, in particular the oxides, hydroxides, borates, carbonates, methoxides and ethoxides (e.g. zinc oxide and barium carbonate), which compounds is included as part of the filler and neutralizes the residual free carboxyl groups of the alkyd.  Other optional ingredients are (a) catalysts such as benzoyl, succinyl, acetyl, toluoyl, p-bromobenzoyl, anisoyl, chloroacetyl, acetyl benzoyl and furoyl peroxides, t-butyl perbenzoate, di-t-butyl perphthalate, per-acetic and perbenzoic acids, di-isopropylene and di-isobutylene ozonides and mixtures; (b) inhibitors such as hydroquinone, pyrogallol, tannic acid and aromatic amines such as aniline and phenylene diamine; (c) lubricants such as zinc stearate; and (d) unspecified plasticizers and colouring matter. Sheets of the compositions may be granulated by pressing through a fine-mesh screen or by subjecting to high-speed cutting action. The moulded products have improved mechanical and electrical properties and water resistance and, in some cases, improved flame resistance.

Filed: 1917-03-29
Abstract: 113,356. British Thomson - Houston Co., (General Electric Co). March 29, 1917. Electro - magnets. - A winding for electric apparatus has one terminal at its centre. The turns progress from this terminal in the same direction round the flux path to the ends which are joined together and form the other terminal. The transformer shown in Fig. 1 has a core 10 of the three-legged type with a cylindrical low voltage winding 11 on the core leg 13. The high voltage winding consists of a number of disk coils with one conductor per layer. The central coil 16 is connected between the terminal 17 and the coils 18, 19, and consequently acts as a buffer coil, the transformer being intended for use in a threephase system Y-connected on the high potential side. Between the coil 18 and the end 26 of the winding are arranged further coils in sections 22, 23, 24, 25. Similar coils are arranged between the coil 19 and the end 28 of the winding. The ends 26, 28 may be earthed by connexion to the core. The internal diameter of the coil sections gradually diminished from the coil 16 to the ends of the windings while the external diameter increases. The turns of the central coils are heavily insulated and the sections 16, 18, 19 are enclosed between two insulating cylinders 33. Insulating cylinders 34 enclose the central sections as far as the sections 23 and the whole winding is enclosed by insulation which separates it from the core and from the low tension winding. Taps 37, 38 may be provided to vary the active number of turns. In the modification shown in Fig. 4 the divided winding 60 is disposed on two legs of the core and is provided with terminals 61, 62, the winding being arranged to produce flux in one direction round the core when current enters at one terminal and leaves at the other.
