The copolymers may be prepared by polymerizing a -fluoroacrylonitrile and one or more of the above comonomers in bulk, solution, suspension or emulsion using peroxide or azo initiators (several are specified) alone or in redox systems; polymerization may also be initiated by high-energy irradiation, e.g. gamma rays and beta rays.

Title: Improved bis(beta-hydroxyethyl) terephthalate
Inventor: OWEN EDMUND CECIL
IPC: C07C69/82
Filed: 1953-11-18
Abstract: Bis - (beta - hydroxyethyl) - terephthalate obtained from terephthalic acid made by the nitric acid oxidation of a substituted aromatic compound is purified by treating an aqueous solution thereof with sodium hyposulphite and isolating the bis - (beta - hydroxyethyl) - terephthalate from the solution.  The process is preferably carried out at or near pH7, and it is usually necessary to add an alkaline substance to the aqueous soultion of the bis-(beta-hydroxyethyl) - terephthalate, e.g. hydroxides, carbonates, bicarbonates, salts of weak acids and preferably a sparingly soluble carbonate, e.g. calcium carbonate. The amount of sodium hyposulphite required may be determined by using aqueous methylene blue as an external indicator.  In examples: bis-(beta-hydroxyethyl)-terephthalate in aqueous solution is treated with sodium hyposulphate after addition of calcium carbonate (1); and after addition of ammonium hydroxide (2); after a similar treatment in (1) the aqueous solution is treated with decolorizing charcoal (3).

Abstract: 1,237,272. Tetrahydroisoquinolines. INSTITUT PASTEUR. 5 July, 1968 [5 July, 1967], No. 32221/68. Heading C2C. Novel tetrahydroisoquinolines of the formula in which R is -CN, -COOH, -COOR<SP>11</SP>, -CONH 2 , -CONHR<SP>11</SP> or -CON(R<SP>11</SP>) 2  where R<SP>11</SP> is an alkyl or aryl group and R<SP>1</SP> is hydrogen or an alkyl or aryl group, are prepared by reacting a benzylamine of the Formula I in which X is halogen, with an alkali metal base under anhydrous conditions. The cyclization is preferably effected in a liquid medium, e.g. liquid NH3, tetrahydrofuran or hexamethylphosphotriamide, using Na or K amide. The compounds in which R is -CN may be hydrolysed, optionally in the presence of an alcohol, to obtain the tetrahydroisoquinolines in which R is -CONH 2 , -COOH or -COOR<SP>11</SP>. The N- mono- and -alkyl amides may be obtained from the free acid and an amine. The free acid may also be pyrolysed in the presence of a base to obtain the tetrahydroisoquinoline in which R is hydrogen. Examples relate to the preparation of N-methyl compounds some of which are isolated as the hydrochloride, picrolonate and picrate. In Example 3 a minor proportion of a compound of the formula in which R<SP>1</SP> is methyl and R is -CN is obtained by replacement of chlorine by -NH 2  from the NaNH 2  base. A benzylamine reactant, N-ochlorobenzyl - N - methyl - 3 - aminopropionitrile is prepared by heating chloro-2-chloromethylbenzene with N-methyl-3-amino-propionitrile; the amino nitrile product may be hydrolysed with HCl to methyl N-o-chlorobenzyl-N-methyl- 3-aminopropionate which can be isolated as its picrate.

Abstract: 268,031. Automatic Telephone Manufacturing Co., Ltd., and Woodland, C. R. Dec. 23, 1925. Addition to 164,313. Tell-tale apparatus.-The device of the parent Specification for indicating the condition of a telephone line is modified by causing the indicating member to be influenced by the magnetic field of the relays instead of mechanically. A V-shaped piece 1 of magnetic material is pivoted on the inside of the cover of the line and cut-off relays and its lower end passes through a slot to the outside of the casing to act as the indicator. When the line is idle the indicator is in the position shown. When the line relay is energized, its fixing screw 5 attracts the projection 9 on the lower part of the indicator and subsequently, when the cut-off relay is energized, its fixing screw 4 attracts the member 11 on the arm 8 and so holds the indicator in the " outgoing " position. On an in - coming call, the cut-off relay alone is energized and the member 10 on the arm 7 is attracted since it is normally nearer to the screw 4 than the arm 8.
