Title: Improvements in the manufacture of aliphatic anhydrides
IPC: C07C51/56
Filed: 1933-08-23
Abstract: In the production of aliphatic anhydrides such as acetic anhydride by reacting a salt of the organic acid with a pyrosulphate as described in Specification 136,574, [Class 2 (iii)], or a pyrophosphate as described in Specification 299,342, [Class 2 (iii)], one of the reactants is a salt of ammonium or other volatile base which may be a primary, secondary or tertiary acyclic or cyclic amine, for instance the mono-, di-, and tri-methyl, ethyl, propyl and isoamyl amines, and pyridine. Ammonium acetate or acid ammonium acetate may be heated with sodium sulphate, yielding acetic anhydride and sodium and ammonium sulphates, which on further heating yield sodium pyrosulphate and ammonia which is available for the production of more ammonium acetate.  Preferably the ammonium salt should be anhydrous; the dehydration of the salt may be effected in a vacuum or the water may be removed as an azeotropic mixture with benzene, toluene, xylene, dichlorethylene, ethylene dichloride or the like. Preferably the reaction between the acetate and pyrosulphate or pyrophosphate is effected in the presence of a diluent such as a hydrocarbon or chlorinated hydrocarbon or the acid whose anhydride is to be produced.  The temperature of the reaction may be 100--140 DEG C., and may be the boiling-point of the diluent. Alternatively the organic salt may be a salt of a non-volatile base such as soda or potash, which is reacted with a pyrosulphate or pyrophosphate of the volatile base such as ammonia.  In an example, anhydrous neutral ammonium acetate is heated with anhydrous sodium pyrosulphate and glacial acetic acid under reflux, and the anhydride is then distilled off.  The residue is then heated to liberate ammonia and convert the sodium salt into pyrosulphate.

IPC: B65H23/04
Filed: 1950-09-29
Abstract: 697,974. Automatic registration control systems. ENGLISH ELECTRIC CO., Ltd. Sept. 28, 1951 [Sept. 29, 1950], No. 23897/50. Class 38 (iv). In a system for automatic longitudinal registration of a web with an element operating on it, marks or apertures on the web co-operate with marks or apertures on a device driven with the element to form an area which varies, upon error in registration, to vary an amount of light which controls register, the total area controlling the light at any instant remaining constant if registration is constant. As shown, in order to cut off equal lengths from a paper web 6 issuing from feed roll 2 driven by a constant speed motor 1, the speed of a rotary knife 4 is automatically controlled by controlling a reversible servomotor 15 which, through a differential gear 3, increases or decreases the speed of drive of knife 4 from motor 1. Black marks 7 printed on the web run beneath apertures 8 in a scanning disc 5 driven with rotary knife 4 so that when the knife and the web are in correct register the web beneath half of the aperture is black. Lack of register in one sense or the other thus increases or decreases the amount of light which is reflected from a lamp 9 through a gate 11 on to a photo-cell 12 to control, through an amplifier 13, the resultant energization of a split field winding 14 of motor 15 which then runs in the appropriate direction to correct register. A tachometer generator 17 provides velocity feedback. Constant speed motor 1 may alternatively derive rotary knife 4 direct, the correction then being applied to the paper feed.
