Title: Improvements relating to the generation of modulated carrier wave energy
Inventor: LEYTON ERIC MCPHAIL
IPC: H03C1/50
Filed: 1952-11-04
Abstract: 748,935. Mediating systems. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Nov. 2, 1953 [Nov. 4, 1952], No. 27690/52. Class 40 (5). An aerial in a bridge circuit receives amplitude modulated carrier energy produced by combining, in said circuit, the outputs of two channels in which carrier energy of predetermined phase relationship and of the same frequency is phase-modulated by the signal, a vestigial side-band characteristic being produced by phase displacement of sound frequencies of the modulating signal for one of the channels. In the television transmitter described, the aerial 19 and a dummy load 20 are connected in a bridge circuit 8 ... 18 of the type described in Specification 581,167. The phase modulators 2, 4 feed amplifiers 6, 7 respectively, one of which is connected to one of the pairs of conjugate points of the bridge, and the other to the other pair. The modulators are fed in phase quadrature with carrier energy from a common source 5 and modulating signals from a video source 1. In order to produce the required amplitude modulation characteristic in the aerial 19, the video source is connected directly to the modulator 2 and through two parallel circuits to the modulator 4. One of these circuits contains a low-pass filter 3a which passes only those frequencies required to form the vestigial side-band, while the other circuit contains a high-pass filter 3b, passing the remainder of the modulating frequencies, followed by a network 3c which produces a phase shift of 90 degrees.

Abstract: Dyestuff intermediates useful as colour couplers in color photography, producing quinone-imine types of dyestuff and having the general formul  <FORM:0626321/IV (b)/1> and <FORM:0626321/IV (b)/2> where n is nought or an integer from 1-8 and D is a phenolic nucleus, are produced by reacting a phenol having a reactive position ortho to the hydroxy groups with a polyfunctional monomeric lower alkyl ether of a methylol carbonamide containing 1 or 2 C atoms in the alkyl group at temperatures from 0-50 DEG  C. in the presence of a mineral acid catalyst and preferably in a solvent, e.g. methanol and like water-soluble alcohols.  Preferred carbonamides are di(methoxymethyl)-adipamide, -oxamide succinamide, -sebacamide, -glutaramide, -urea, and -melamine, and dimethylol-urea, -urondimethyl ether, phenols specified are a -naphthol, 1-naphthol-5 sulphonic acid, 2.4-dichloronaphthol, 1.5-aminonaphthol, m-nitro-naphthol; m-cresol; xylenols; diethyl or acetyl-m - aminophenol, dibromophenol, a  - hydroxy quinoline; o-hydroxy diphenyl; thymol.  In examples: (1) a mixture of 7 gs. a -naphthol, 5 gs. dimethoxymethyl adipamide, 2.5 gs. benzaldehyde-o-sulphonic acid and 200 cc. ethanol was agitated during the slow addition of 50 cc. H2SO4.  On standing overnight the mixture was poured into cold water whereupon a solid was deposited; (2) a mixture of 15 gs. a -naphthol, 12 gs. dimethoxymethyl urea in methanol was reacted similarly.  Alkyl ethers of methylol carbamides sym. di(methoxymethyl) urea is obtained by warming on a water bath for two hours 1000 gs. dimethylolurea in the form of an aqueous paste, 3000 gs. methanol, and 1.5 gs. phthalic acid; the solution obtained is filtered, concentrated to 1 1/2 litres under vacuum, neutralized to phenolphthalein and cooled to 0 DEG  C. Crystals of m.p. 95-96 DEG  C. are obtained.  Sym di(methoxy-methyl) oxamide is obtained by reacting oxamide, 37 per cent formaldehyde, and potassium carbonate to give dimethyloloxamide which is then further reacted with methanol as above.  Sym. di(methoxymethyl) adipamide is obtained by first preparing dimethylol adipamide in dried form which is then ground, suspended in methanol and dry HCl passed into the suspension.  Diethyl ether is added to the solution obtained and on cooling crystals of the adipamide (m.p. 116 DEG  C.) separate out.  The Specification as open to public inspection under Sect. 91 described the addition of modifying agents containing solubilising groups which condense with the dimethylol urea &c. to form polymers, e.g. benzaldehyde-o-sulphonic acid metal salts as exemplified in example (3) (Cancelled), which is otherwise similar to example (2), where it is stated that such addition results in a more soluble and dispersible medium giving a powerful blue green dye. This subject-matter does not appear in the Specification as accepted.
