Patent GB-898780-A (GB)
Title: 3-diacetamido-2,4,6-triiodobenzoic acid and derivatives thereof
Inventor: ASHLEY JULIUS NICHOLSON
IPC: A61K49/04
Filed: 1958-10-02
Abstract: The invention comprises compounds of the general formula <FORM:0898780/IV (b)/1> where R represents a hydrogen atom, an alkyl1 group containing from 1 to 6 carbon atoms, an alkali or alkaline earth metal or an ammonium ion in which the valencies of the nitrogen are satisfied at least in part by hydrogen, any remaining valencies being satisfied by alkyl or hydroxyalkyl groups containing not more than 6 carbon atoms which are suitable for use in X-ray contrast media (see Group VI).  Compounds of the above formula in which R represents a hydrogen atom or an alkyl group containing from 1 to 6 carbon atoms may be obtained by acetylating the corresponding amine or mono-acetylated amide.  The esters of the invention may be obtained by esterification of the free, acid e.g. by converting the latter to an alkali metal salt and reacting the latter with an appropriate alkyl sulphonic ester or sulphate, e.g. n-propyl toluenep-sulphonate or diethyl sulphate.  The acetylation may be carried out with acetic anhydride in the presence of sulphuric acid or acetyl chloride in the presence of dimethyl aniline or pyridine. The examples relate to the preparation of methyl ethyl, n-propyl, n-butyl and n-amyl esters and sodium diethanolamine salts of 3-diacetamido2,4,6-triiodobenzoic acid.  Ethyl 3-acetamido-2,4,6,-triiodobenzoate for use as starting material is obtained by treating the corresponding sodium salt with diethyl sulphate.  The methyl ester is prepared similarly.  n-Propyl, n-butyl and n-amyl 3-acetamido2,4,6,-triiodobenzoate for use as starting materials are obtained by reacting the appropriate alkyl toluene p-sulphonate with sodium 3-acetamido 2,4,6-triiodobenzoate.ALSO:An X-ray contrast medium comprises a compound of the general formula <FORM:0898780/VI/1> where R represents a hydrogen atom, an alkyl group containing from 1 to 6 carbon atoms, an alkali or alkaline earth metal or an ammonium ion in which the valencies of the nitrogen are satisfied at least in part by hydrogen, any remaining valencies being satisfied by alkyl or hydroxyalkyl groups containing not more than 6 carbon atoms in association with a pharmacologically acceptable diluent (see Group IV (b)).  The alkyl esters may be used in the form of a suspension in oil, such as arachis oil, or in water. The salts may be used in aqueous solutions.  In examples the preparations of an arachis oil suspension of n-propyl 3-diacetamido-2: 4 : 6-triiodobenzoate and an aqueous solution of the diethanolamine salt of 3-diacetamido-2: 4 : 6-triiodobenzoic acid are described.

Title: Improvements in and relating to electric distribution systems
IPC: H02J1/16
Filed: 1925-12-18
Abstract: 264,006. British Thomson-Houston Co., Ltd., and Liddiard, H. W. C. Dec. 18, 1925. Equalizing load on generator.-A motor-generator M, G, provided with a flywheel derives energy from a system A and supplies a system B which is subjected to a fluctuating load. Both machines have shunt fields supplied from the system A and the generator G has a series field SF<1> for normal regulation due to its own load. The motor M has a series field SF<3> arranged to cause a large drop in speed upon increase of load, thereby causing the flywheel to transfer its energy to system B. However, a large drop of speed causes the generator voltage to fall below normal, so this is prevented by providing the generator with another field SF<2> in series with the motor.

Abstract: 1,210,774. Attaching accessories to garments. M. FELDINGER. 26 June, 1969 [24 Jan., 1969], No. 32248/69. Heading A3V. A method of attaching an accessory, e.g. a hood 2, to a garment, e.g. a cloak 1, comprises inserting through the hood and cloak connecting elements made of synthetic material, these elements having a stem 4 and end stops 7, 8 and being inserted by means of a bored needle which pierces the material, the element then being ejected by a plunger 12. The end stop 8 travels along the needle guided in two diametrically opposed longitudinal slots whilst the stop 7 is bent parallel to the stem 4 within the bore 11 and retains its normal position due to the elasticity of the material after having been ejected from the needle. In a modified element one of the end stops is spherical with the other stop of bar shape which is forced through the needle by the plunger, the spherical stop being on the outside of the needle by means of the stem extending through a longitudinal slot therein. Either the garment or accessory may be provided with a reinforced row of holes through which the elements pass, making the attachment releasable.
