Title: Preparation of formylated or acetylated fatty compounds and corresponding hydroxylated compounds, including isomers thereof
IPC: C07C69/04
Filed: 1953-07-08
Abstract: Formylated or acetylated fatty compounds are prepared by reacting one or more fatty compounds (as hereinafter defined) with formic or acetic acid at a temperature between about 70 DEG  C. and the normal boiling point of the reaction mixture in the presence of a strong mineral acid catalyst, sufficient of the formic or acetic acid being present to allow its addition to a double-bond of the fatty compound. In a modification, formic acid is used as reagent and also as catalyst.  The acylated fatty compounds may be hydrolysed yielding corresponding hydroxylated fatty compounds.  The fatty compounds used as starting materials are natural and synthetic glycerides of unsubstituted unsaturated fat acids, the fatty acids obtained by hydrolysis of such glycerides, esters of such fatty acids and unsaturated fatty alcohols obtained by the hydrogenation of such glycerides; they include soybean, cotton seed, peanut, lard and olive oils, oleic, elaidic, linolenic, undecylenic and petroselinic acids, the methyl, ethyl and glyceryl esters of these acids, and oleyl alcohol.  The strong mineral acid catalyst is preferably per chloric acid but others, e.g. sulphuric acid, may be used.  The acylating acid may serve as a solvent but a mutual solvent is usually employed when acylating a glyceride.  The products are believed to be isomeric mixtures.  The acylated compounds may be used as plasticizers, lubricants and hydraulic fluids; the corresponding hydroxylated compounds may be used for the same purposes and as surface-active agents and components of alkyd resins.  In examples (1) oleic acid is refluxed with formic acid using perchloric acid as catalyst yielding formoxy stearic acid which is saponified with caustic soda and acidified to hydroxy-stearic acid; the conversion is substantially unchanged if the acid catalyst is omitted; reference is made to the replacement of the formic acid by acetic acid yielding the acetoxy compound and of the oleic acid by elaidic acid; (2) methyl oleate is reacted as in (1) to give methyl formoxystearate; (3) oleyl alcohol is reacted with formic acid as in (1) yielding formoxy octadecyl formate which is saponified to give hydroxy-stearyl alcohol; (4) linolenic acid containing some oleic acid is similarly formoxylated and the product hydrolysed to a mixture of hydroxy acids which are esterified with methanol and fractionated to yield the methyl esters of hydroxy octadecenoic and dihydroxy-stearic acids; (6) soybean oil is refluxed with formic acid in butyl acetate with perchloric acid as catalyst yielding formoxylated soybean oil.

Patent GB-613694-A (GB)
Title: Improvements in processes for coating surfaces
IPC: C04B28/02
Filed: 1946-06-27
Abstract: A process for coating surfaces with a hydraulic cement-binder composition comprises directing on to the surfaces commingling sprays of an aqueous dispersion of a binder and of a hydraulic cement slurry.  The spraying may be carried out by means of a spray producer having an annular orifice surrounding a nozzle and a hollow needle coaxially mounted within the nozzle, the dispersion of the binder being supplied to the hollow needle, the cement slurry to the nozzle and compressed air to the annular orifice.  The aqueous dispersion of the binder advantageously includes a substance capable of accelerating the setting of the cement or such an accelerator may be separately sprayed as an aqueous solution or the surface may be moistened with its solution before the spraying operation.  Suitable binders include natural or artificial dispersions of natural rubber, aqueous dispersions of a synthetic rubber, or of bitumen, tar, vulcanized oils, or of thermoplastic resins such as polyvinyl-acetate.  Preferably the aqueous dispersions of these materials contain from 50 to 65 per cent by weight of the binder. Specified cements are Portland cement and aluminous cement or mixtures of the two, and the slurry may also contain an inert finely-divided mineral filler such as fine sand.  Specified accelerators are sodium lactate, sodium silicate and triethanolamine and the preferred amounts are between 1 and 10 per cent of weight of the aqueous dispersion of the binder.  Specification 566,543, [Group XXIX], is referred to.

Title: Improvements in and relating to electron discharge devices and electron emitting cathodes therefor
IPC: H01J17/24
Filed: 1922-07-15
Abstract: 184,446. British Thomson - Houston Co., Ltd., (Assignees of Langmuir, I.). Aug. 11, 1921, [Convention date]. Vacuum tubes; low-pressure metallic-vapour apparatus.-The cathode comprises tungsten or other refractory metal, thorium, or a compound such as thoria and carbon. The introduction of carbon, preferably in the proportion of twothirds per cent, and, in any event, below 3 per cent, prevents reoxidation of the active thorium, and reduces thoria to the active state. According to one method, the filament is prepared by squirting a mixture of tungsten, thoria, and a carbonaceous binder. According to another method, a tungsten filament 2, containing three-quarters per cent of thoria, is mounted in a bulb 1 with an anode 3 of tungsten or molybdenum. The bulb is connected with a pump through a tube 6, and with a bulb 7 containing a substance giving a low pressure of carbonaceous vapour, such as anthracene or naphthalene. The bulb 7 may be surrounded by a receptacle 8 containing a freezing-agent to reduce the vapour pressure; in the case of naphthalene, the temperature of the bulb 7 is reduced to -20 to -30C., the vapour pressure being 0.1 to 0.01 micron. The filament is heated at about 2300 absolute for a few minutes in contact with the hydrocarbon vapour, tungsten carbide being formed. The heating is continued until the resistance of the filament shows an increase of 15 to 25 per cent above that of the filament when cold; this condition corresponds with the presence in the filament of about two-thirds per cent of carbon. The vapour is then removed from contact with the cathode by sealing a contraction 9, or by cooling the bulb 7 by liquid air. Gas is removed from the anode by electron bombardment from the cathode, and withdrawn by the pump. A non-carbonaceous reducing material, such as sodium or potassium, may be introduced into the bulb 1, or, when some positive ionization is desired, caesium may be provided by adding a mixture of caesium halide and metallic calcium as a paste to some part of the bulb. When ionization of residual gases or vapours is not desired, a reagent having a lower vapour pressure than the alkali metals may be used, for example, magnesium, calcium, or strontium. For this purpose, a tungsten filament 11, containing magnesium, may be mounted in the bulb 1, the magnesium being volatilized and deposited on the walls of the bulb when the filament is heated. After sealing off the bulb at a contraction 10, the filament may be heated again to absorb any oxygen or water vapour driven off from the glass. The cathode is then heated for a short time to about 2700 absolute to volatilize any thorium oxide on its surface. Further heating for a few minutes at 2200 absolute causes reduction of thoria by carbon, the active thorium being brought to the surface. In use the cathode is heated to a temperature below 2200 absolute, for instance 2100. Specifications 7655/06 and 148,132 are referred to.

Abstract: 946,894. Radiation dosemeters. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 23,1962 [May 26, 1961], No. 19866/62. Heading G1A. A radiation e.g. X-ray dose received by an ionisation chamber is measured by applying the ionisation current to charge a capacitor to a voltage dependent upon the dose, combining the voltage with a steadily increasing voltage of upposite polarity and using the time taken for the combined voltage to reach a predetermined value as an indication of the dose. When mains current is applied to terminals 1,a relay E closes its contact e to establish a voltage U v  across the capacitor C 4 . The X-ray source is switched on and at the same time a relay B switches its contacts to energize relays F and G. As a result contact e opens and the point P is connected to earth so that the ionisation current of the chamber 8 adds to the voltage U v , which is of such a sense as to cut of the triode 7. At the end of the dose relay B switches back the contacts b 1 , b 2 , b 3 , but relays F and G are kept energised by a holding contact f 1 . This connects capacitor C 4  in series with a network comprising capacitors C 5  and C 6  across which a steadily increasing voltage of opposite polarity to that across capacitor C 4  is built up. At the same time, a free-running multivibrator 13 is switched on and its output pulses are counted by a counter 15. When the voltage on the grid of triode 7 has reached a predetermined value, a switching transistor 17 operates to switch off multivibrator 13 and return the circuit to its stand-by condition. The counter reading indicates the received dose.
