Title: Improvements in or relating to anion-exchange resins
IPC: B01D15/04
Filed: 1952-05-06
Abstract: A solid, water-insoluble, anion exchange resin is obtained by reacting with an amine, a haloalkylated proliferous copolymer prepared from a mixture containing 70 to 99.5 per cent. by weight of a copolymerizable polyolefinic organic compound of which the olefinic linkages are in the acyclic portion of the molecule, so that the haloalkyl groups are attached to the aromatic nuclei in an amount equal to at least one haloalkyl group for every fifteen aromatic nuclei in the copolymer.  The polyolefinic compounds include divinyl benzene, butadiene, isoprene, bimethylallyl, biallyl, trivinyl benzene, dimethallyl ether and sulphide, vinyl allyl ether, diallyl maleate, and 2-chloroalkyl crotonate.  The copolymerization is carried out at a temperature between 20 and 80 DEG C. in the absence of oxygen with less than 0.5 per cent. of a catalyst such as benzoyl, lauroyl and stearoyl peroxides, t-butyl hydroperoxide and inorganic per salts, and may be seeded with a proliferous copolymer.  Bromo- or chloroalkyl groups having the general formula CnH2nX, where n is 1 to 4 and X is chlorine or bromine, are introduced by the usual methods and mono-and diamines, such as methyl, dimethyl, n-butyl, isobutyl and dibutylamines, aniline, benzidine, o-, m- and p-toluidines, xylidines, a - and b -naphthylamines, naphthalene diamine, benzyl and dibenzylamines, phenylene diamine, benzyl aniline, benzyl ethylamine, methyl aniline, cyclo- and dicyclohexylamines, di-ethylene triamine, triethylene tetramine, tetraethylene pentamine, 3, 31-iminobispropylamine and propylene diamine and tertiary amines such as trimethyl-, triethyl- and dimethylbenzylamines, dimethylaminoethanol, dimethylaniline, dimethylaminopropene, tributylamine and N-methylmorpholine are used.  After purification by steam distillation, the basic form may be prepared by treatment with alkali metal hydroxide. Examples describe the bulk proliferous copolymerization of styrene with butadiene, isoprene, or commercial divinyl benzene (containing ethyl styrene) or a mixture of butadiene and commercial divinylbenzene.  The copolymer was swelled with ethylene dichloride and chloromethyl ether and anhydrous aluminium chloride was added.  A toluene solution was reacted with dimethylamine, diethylenetriamine, dimethylaminoethanol, or trimethylamine and the products steam distilled.

Title: Diisocyanate-modified polyester elastomers
IPC: C08G18/32
Filed: 1954-04-23
Abstract: Elastomeric products are obtained by reacting a hydroxy terminated linear polyester with an excess of diisocyanate and simultaneously or subsequently reacting the product with a glycol containing a tertiary amino group or a nitro group.  The tertiary amino group accelerates and the nitro group retards the reaction. The glycol may be used in admixture with unsubstituted glycols and may be used in a quantity less than that equivalent to residual isocyanate groups, in which case the product is moulded during the course of the reaction, or in a quantity equivalent to the available isocyanate groups in which case 1-5 per cent by weight of the product of a diisocyanate is incorporated prior to moulding.  The polyesters may incorporate minor amounts of aromatic acids, diamines, hydroxyamines and glycols containing groups influencing the subsequent rate of reaction of the modified polyesters with glycols. In examples: (1) a glycol adipic acid polyester is reacted with 1,5-naphthylene diisocyanate and the product mixed with N,N-di-(hydroxyethyl)-a -naphthylamine. The mixture is cast into moulds and heated for 35 hours at 100 DEG  C. (2) Similar to (1) but adding the amineglycol to the polyester. (3) Similar to (1) but using a quantity of the amine glycol equivalent to the free isocyanate groups with subsequent addition of more diisocyanate.  (4) Similar to (1) but using a mixture of butane diol and N,N-di(hydroxyethyl) cyclohexylamine.  (5) Similar to (1) but using instead of the amineglycol, 2-nitro - 2 - ethyl - 1,3 - propanediol.  Other amine glycols referred to are N,N-di-(hydroxyethyl) aniline and substitution products thereof. Specification 700,608 is referred to.

Title: Improvements in and relating to the manufacture of organo arsenic compounds
IPC: C07F9/70
Filed: 1927-05-03
Abstract: 293,152. Stickings, R. W. E., and May & Baker, Ltd. May 3, 1927. Carbamido-arylarsinic acids and their inner anhydrides are prepared by condensing amino-arylarsinic acids and their substitution products with a cyanogen halide in an aqueous medium. The cyanogen halide combines with the amine group and the product becomes hydrolyzed to the carbamido compound. When a substituent capable of condensing with the urea residue is present in the o-position thereto, heterocyclic arsinic acids result; if the substituent is a hydroxy group benzoxazoles are formed, if an amino group benzimidazoles result, and if a carboxyl group the compound formed is a benzdiazine. The products possess therapeutic properties. According to the examples, (1) the sodium salt of p-aminophenylarsinic acid is condensed with an aqueous suspension of cyanogen bromide, to form phenylurea-parsinic acid, (2) 3-amino-4-hvdroxyphenylarsinic acid and cyanogen bromide yield the inner anhydride of 2-hydroxyphenylurea-5-arsinic acid, (3) 3-amino-4-carboxyphenylarsinic acid condensed with cyanogen chloride gives the inner anhydride of 2-carboxyphenylurea-5-arsinic acid.

An oscillator 1 is stabilized relative to a stabilized pulse source 3 of lower frequency by applying its oscillations and the pulses to a gated mixer 4 only rendered conductive during pulses, the variable amplitude output pulses energizing a high-frequency amplifier 12 tuned to the fundamental or a harmonic of the pulse frequency, whose detected output retroactively stabilizes the frequency of the oscillator 1 through a variable reactance tube 2. According to the invention, instability due to any sloping phase/frequency characteristic of the tuned H.F. amplifier 12 is compensated, e.g. by a phase shift compensating network 10, 21 including a circuit 10 tuned to the same frequency as the amplifier, but preferably of lower Q, connected across the input tuned circuit 9 of the amplifier 12. Alternatively the amplifier input (network 10, 21 being omitted), may be from the primary of a band-pass filter. Also, a resistor in series with the tuned anode circuit of the amplifier may further limit the phase/frequency shift. In a modification a stable interpolation oscillator tunable in steps is beat with the oscillator 1 in a mixer, and the amplified sum or difference frequency applied to the gated mixer 4 and controlled.
