Filed: 1936-01-29
Abstract: 469,736. Sound-reproducing devices; electric horns. RAMSAY, F. R. F. Jan. 29, 1936, No. 2652. [Class 40 (iv)] Electromagnetic sound-producing apparatus, particularly for use as a vehicle horn, comprises a pair of coaxial (and preferably solid) polepieces a, b having a narrow air-gap between their adjacent ends, a fixed and rigid iron part f carrying the polepiece a and a movable rigid iron part i carried by the polepiece b, the said parts f, i being adapted to carry relatively heavy magnetic fluxes, a winding d surrounding the adjacent ends of the polepieces and arranged in the space bounded by the iron parts f, i, and a resilient diaphragm c held at its periphery by a fixed part g and connected at its centre to the movable polepiece, the arrangement being such that large air-spaces are provided between the ends and periphery of the winding and the iron parts so that when the circuit through the. winding is closed the first effect is to produce a strong flux through the iron parts and polepieces, but thereafter when the diaphragm is in rapid motion the fluctuating magnetic fluxes can by reason of the said air-spaces take up an alternative path through these spaces and the adjacent ends of the polepieces. The movable polepiece b carries a plate i forming a small gap h with the fixed part g and is slightly smaller than the fixed polepiece a which carries the winding d. The diaphragm is clamped between the part g and a part k carrying a horn m and a cover t is secured to a fixed bridge-piece v. An interrupter for the contact assembly s is formed by a rod o passing through holes in the polepieces and adjustably secured to the movable polepiece b. The winding d may be mounted in a recess which is V-shaped, Fig. 2 (not shown), or semicircular, Fig. 3 (not shown), formed by the polepieces a, b which are preferably of the same diameter. As described in connection with Fig. 4 (not shown), the interrupter rod may pass through a hole in the fixed polepiece and engage the upper surface of the movable polepiece, and the plate k may be replaced by a casing having a spiral passage leading to a relatively short horn.

Abstract: N-acylated sulphamides are produced on reacting carboxylic acids at elevated temperatures with sulphonyl isocyanates of the general formula R-SO2-N=C=O, wherein R represents an aliphatic, aromatic, araliphatic, cycloaliphatic or heterocyclic group.  Carboxylic acids mentioned include acetic, propionic, butyric, pivalic, stearic, oleic, crotonic, oxalic, maleic, fumaric, adipic, muconic, chloracetic, nitroacetic, benzoic, toluic, naphthoic, chlor-, bromo-, nitro-, methoxy-benzoic, phenylacetic, phenylpropionic, phthalic, terephthalic, cyclohexyl - carboxylic, cyclohexenyl - carboxylic, cyclopentyl - carboxylic, pyridine - carboxylic, pyrazol-carboxylic and furan-carboxylic acids.  Mixtures of acids, e.g. the acid fractions of paraffin oxidation products, may be used.  The components may be reacted in the presence of diluents such as dichlorobenzene, trichlorobenzene, nitrobenzene, diethylbenzene or heavy benzine. Water is preferably excluded.  The N-acylsulphamides are soluble in solutions of bicarbonate or alkali hydroxides.  In examples: N-acyl-sulphamides are prepared by heating p-toluene sulphonyl isocyanate with (1) glacial acetic acid; (2) benzoic acid; (3) phenylacetic acid; (4) stearic acid; (5) oleic acid; (6) first runnings fatty acids from paraffin oxidation of boiling range 180-260 DEG  C. at 760 mms. Hg.; (7) adipic acid; (8) nicotinic acid; and (9) abietic acid or colophony.  A mixture of alkyl sulphonyl isocyanates, such as may be prepared from alkyl sulphonic acid chlorides obtainable by the action of sulphur dioxide and chlorine on a mixture of liquid paraffin hydrocarbons, treated similarly to the p-toluene sulphonyl isocyanate in example (1) yields a mixture of N-acetylalkylsulphamides; N - benzoylsulphamide may be obtained using benzene sulphonyl isocyanate in a similar process to that of example (2), and o-toluene sulphonyl isocyanate may be used in a similar process to that of example (4).  The product of example (6) may be dissolved in soda solution and salted out as the sodium salt and from an aqueous solution of the latter a manganese salt, soluble when dry in xylene and suitable as a drier, may be precipitated by the addition of manganous salts. The product of example (9) forms water soluble salts, e.g. with caustic soda solution or triethanolamine. Specification 692,360 is referred to.
