Title: Improvements in or relating to thermosetting compositions based on carbohydrates
Inventor: WORTHINGTON JOHN EDWARD
IPC: B22C1/22
Filed: 1960-01-14
Abstract: A thermosetting composition comprises (a) at least 51% of a mono- or di-saccharide; a minor proportion of (b) a carboxylic acid; and still smaller proportions of (c) an amine; and (d) formaldehyde, a formaldehyde-yielding material of an anhydride of a polycarboxylic acid as crosslinking agent. Specified reactants are: for (a)-dextrose, fructose, sucrose, maltose and lactose; for (b)-citric acid, gallic acid and tannins (e.g. sulphited quebracho or myrabolam); for (c)-aniline, m- or pphenylene diamine and glutamine, and dicyandiamide and/or melamine and salts of such amines; for (d)-formaldehyde, paraformaldehyde, hexamethylene tetramine, maleic anhydride or phthalic anhydride.  The saccharide may be used in admixture with an inorganic acid or a salt liberating such an acid on heating (e.g. hydrochloric acid, phosphoric acid or ammonium sulphate). The compositions may be used to make sintered or formed metal products (see Division C7), but are particularly useful in the production of shell moulds (see Division B3). For this they are mixed with a granular refractory material (e.g. silica or zircon sand) and possibly a small amount of a substance which will form a coating on the refractory grains (e.g. a solution of ethyl cellulose in methylated spirits, or a melamine-formaldehyde resin together with water).  Foams may be made by heating the compositions in the absence of pressure or in the presence of a blowing agent (e.g. azo dicarbonamide, azo diisobutyronitrile or p-p1-bis (benzene sulphonyl hydrazide)). In example 5, a foam is made by heating a mixture of dextrose monohydrate (containing 6% of ammonium sulphate), sulphited quebracho extracted, melamine and hexamine.ALSO:Porous metal products are made by mixing a powdered metal with a certain thermosetting composition, setting the mixture in a heated mould and then burning out the composition. The thermosetting composition comprises at least 51% of a mono- or di-saccharide, a minor proportion of a carboxylic acid (especially a tannin), and a still smaller proportion of an amine and a cross-linking agent which is formaldehyde, a formaldehyde-yielding material or an anhydride of a polycarboxylic acid.

Title: Improvement in magnetos
IPC: H02K21/38
Filed: 1929-01-21
Abstract: 318,221. Wico Electric Co., (Assignees of Hendrickson, I. E.). Aug. 31, 1928, [Convention date]. Inductor - machines. - A magneto comprises a stationary member consisting of a source of flux to the poles of which are connected cores carrying primary and secondary windings, and a rotary inductor which normally keeps the magnetic circuit closed and is arranged periodically to break the magnetic circuit simultaneously at both polar faces, both polar faces being located on the same side of the rotor axis and at the same time the primary circuit is opened at the contact breaker. As shown in Fig. 6, the stator comprises magnets 11 having polar members 10 which carry primary and secondary coils 12, 13. The laminated inductor 15 is formed with non-magnetic or cut-away portions 18 which as shown in Fig. 3 are slightly longer in the circumferential direction than the pole faces. The stator unit M, Figs. 1 and 4, is supported by a plate 20 bolted to the engine crank-case b. The plate is formed with a slot 22 into which projects a stud 23 in the stator unit. This arrangement allows the stator to be moved radially and to be tilted. A cam 24 on the unit M bearing on the bed-plate effects the tilting. The plate 20 has also a slot 25 through which passes with all-round clearance a screw 26 threaded into the unit M. The outer end of the plate has an outwardly-turned lug 27 in which slides the shank of an eyebolt 28. The screw 26 passes through the eye of the eyebolt and a nut 29 threaded on the shank of the eyebolt serves for drawing the unit M away from the inductor to adjust the air gap. The contact breaker may be located inside the flywheel e and comprises a stationary adjustable contact 38 carried on an arm 35 fixed on a plate 31 adjustable for timing, and a movable contact 39 carried by a pivoted lever 40. A spring 42 tends to keep the breaker points in contact, but in the position shown in Fig. 3 the points are separated by a cam 30 which pressed against the free end of the lever 40. The lever may be formed with a tail 40<1> so that the primary circuit is kept open until the magnetic circuit is closed by the inductor, whereby the flux is rapidly built up in the magnetic circuit. In order to control the engine speed by cutting out the ignition after the engine reaches a certain speed, the cam 30 is carried by one end of a weighted lever 43 which is moved by centrifugal force against the action of a spring so that cam 30 cannot engage with the lever 40. A screw 49 prevents excessive displacement of the lever 43. To stop the engine, a conducting plate i may be operated by a wire j to earth the sparking plug f. The inductor may be formed with a single notch which comes under both stator cores at the same time.
