Abstract: 1,161,535. Gauging devices. PARAMATIC DEVELOPMENT Ltd. 6 March, 1968 [11 March, 1967], No. 11500/67. Heading B3B. [Also in Divisions G1 and G4] In order to indicate the movement and position of a machine tool part, an inextensible tape connected to the part is led round a measuring drum 15 coupled to the planet carrier 19 of a differential gear associated with a unit 22, responsive to movement of one sun-wheel 20 from a datum position, operative to control a motor 23 to drive another sun-wheel 24 in a direction tending to bring the sun-wheel 20 back to the datum position so that the angular displacement of the sun-wheel 24 is a measure of the displacement of the tool part. A lamp and photo-cell in the unit 22 are positioned thereby one on each side of a disc 21, which is carried by the sun-wheel 20 and has a slot 21a extending over 180 degrees positioned to pass the light beam or not according to the angular position of the disc 21. Thus with movement of the sun-wheel 20 from its datum position, circuitry associated with the unit 22 causes the motor 23 to run and drive the sunwheel 24, through worm and worm-wheel 26, 25 in a direction appropriate to restore the sun-wheel 20. The drum 15 drives one counter through gearwheels 30, 31 to register units of displacement e.g. inches and a gear 27, in the drive from the motor 23 to sun-wheel 24, drives another counter through gear 28 to register fractions of the units.

Title: Process for the Extraction of Chlorine.
Inventor: HULIN PAUL LEON
IPC: C01B7/00
Filed: 1916-08-21
Abstract: 126,992. Hulin, P. L. July 17, 1915, [Convention date]. Chlorine is separated from gaseous mixtures by absorption in a solution of a lower chloride such as ferrous chloride or cuprous chloride, or a mixture of such chlorides, and by electrolyzing the product, acidified by hydrochloric acid, to regenerate pure chlorine and the lower chloride for reuse. The chlorine obtained may be liquefied. The original gaseous mixture may be that obtained by the Deacon process, or by the electrolysis of fused chlorides of alkali and alkaline-earth metals. In the latter case it may be scrubbed with water to remove fumes, mainly chlorides, and then passed up one or more earthenware towers down which flows the absorbent solution. The initial solution may contain 30 per cent of ferrous chloride, but after complete conversion to ferric chloride only a part, say a third, of this salt is reduced by electrolysis, in order to avoid the production of iron and hydrogen.

The individual segments forming the confronting electrodes of a MHD generator are interconnected along equipotential planes which are at an angle to the axis of the duct and the unconnected electrodes lying at respective opposite ends of each series are connected through subsidiary loads to the main load. The subsidiary loads are connected in series to form a potential divider so that the appropriate potentials are developed at these end electrodes. The main load is connected between the furthermost upstream of these end electrodes in series with the subsidiary loads. The duct may be constructed of tubes which are closed along the equipotential planes to form the interconnected electrodes as disclosed in Specification 1,097,443, and the end electrodes comprise U-shaped tubular elements. It is stated that the electrodes need not be evenly spaced nor need the number in each series be the same. In the generator system described, fuel, seed and air, preheated by the exhaust gases, are burnt in a combustion chamber and passed through the generator duct in the presence of a magnetic field which can be produced by a superconductive winding. The exhaust gases after leaving the generator duct are passed through seed recovery means and may be used for raising steam for a turbo-generator plant.

Abstract: 509,072. Esters of monochlorhydrin. JOHNSON, G. W. (I. G. Farbenindustrie Akt.- Ges.). April 20,1938, No. 11896. [Class 2 (iii)] Fatty acid mono-esters of monochlorhydrin presumably contain the acyl radicle in the alpha - position, are prepared by reacting aliphatic monocarboxylic acids having at least 4 carbon atoms with preferably an equivalent amount of epichlorhydrin in the presence of catalysts of the Friedel-Crafts type, e.g. aluminium chloride, iron chloride, boron trifluoride and their addition compounds such as sodium aluminium chloride. Suitable acids are butyric, valeric, caproic, oenanthic, capric, oleic, palmitic and stearic acids and their homologues with straight or branched chains, mixtures of acids, e.g. mixed acids from the oxidation of solid paraffins, middle and light oils and other aliphatic hydrocarbons of high molecular weight, and fractions or single bodies separated therefrom. Depending on the reactants, the reaction may take place in the cold or on heating, and solvents, e.g. petroleum ether, ligroin or benzine, and pressure may be used. The catalyst may be removed by treatment with water or alkaline or acid agents, e.g. sodium acetate, or hydrochloric acid and the crude ester may be purified by distillation, preferably under reduced pressure. In examples, epichlorhydrin is reacted with (1) an acid mixture having an average carbon atom number of 8 and anhydrous iron chloride at 100‹ C. ; (2) butyric acid and iron chloride at 65‹ C. ; (3) an acid mixture having an acid value of 216 from the catalytic oxidation of paraffin hydrocarbons and anhydrous aluminium chloride at 80‹ C. The fatty acid esters of monochlorhydrin may be used for the preparation of mixed fatty acid-mineral acid esters of glycerine.

Title: Improvements in the hydration of olefines
IPC: C07C29/04
Filed: 1940-07-25
Abstract: The hydration of ethylene and propylene is effected by absorbing ethylene substantially free from higher olefines in a highly concentrated acid, such as sulphuric or phosphoric acid, diluting the absorption liquor, absorbing propylene in the diluted liquor and finally recovering the oxygen - containing products.  The absorption may be facilitated by the addition of a catalyst, such as silver or silver and copper compounds, and the absorption of ethylene is preferably stopped when about 0.8 molecule of ethylene per molecule of acid has been absorbed, and, using sulphuric acid of 92-98 per cent, water may be added equal to 7-10 per cent of the liquor for the absorption of propylene. The ethylene for the first treatment may be obtained from cracking gases by washing with liquid hydrocarbon to remove higher olefines, and the gas recovered from the liquid hydrocarbon may be used as the source of propylene, residual gas being used as ethylene.
