Filed: 1937-09-23
Abstract: 507,999. Cracking and hydrogenating oils; hydrocarbons. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.) Sept. 23, 1937, No. 25838. Divided out of 503,602. Samples furnished. [Class 32] [Also in Group IV] Non-knocking motor fuels are obtained by subjecting vaporized paraffin hydrocarbons together with benzene and/or its light boiling homologues and/or light boiling hydroaromatic hydrocarbons to a heat treatment at 300- 700‹ C., preferably in the presence of a rigid catalyst having a splitting, and advantageously polymerizing action, and if desired, in the presence of hydrogen. Light boiling homologues of benzene and light boiling hydroaromatic hydrocarbons are those boiling in the boiling range of benzines, i.e. up to 225‹ C. Paraffin hydrocarbons include benzines from paraffin-basic petroleums or from destructive hydrogenation products of coals, tars, or mineral oils, or fractions of the products of reduction of carbon monoxide, and also fractions of hydrocarbons rich in hydrogen obtained by treatment of oils with selective solvents. Pentane, butane and propane are especially suitable. Specified light boiling hydroaromatic hydrocarbons are hydrogenation products of benzene, its homologues and naphthalene. Suitable catalysts are the metals and their compounds of the 2nd to the 8th groups of the periodic system, in particular the sulphides, oxides, phosphates, halides and sulphates of iron, cobalt, nickel, chromium, vanadium, aluminium, zinc, tin, manganese, titanium, magnesium, tungsten and molybdenum (insofar as they remain solid under the reaction conditions). The catalysts may be applied to carriers such as Fuller's earth, bleaching earths, silicates, silica gel, or active carbons or lignite coke which latter may be pretreated with acid substances, e.g. hydrogen fluoride. In an example, butane, benzene and hydrogen at 530‹ C. and under 250 atmospheres pressure are led over a splitting and polymerizing catalyst comprising molybdic acid, zinc oxide and magnesia to obtain a liquid product the fraction of which boiling up to 180‹ C. may be used to improve the non-knocking properties of motor fuels. By hydrogenating refining of' the product at 210‹ C. and 50 atmospheres pressure in the presence of a catalyst consisting of nickel and tungsten sulphides a non-knocking motor fuel is obtained. Samples have been furnished under Sect. 2(5) of benzines boiling up to 180‹ C. obtained by passing (A) liquid hydrocarbons (b.p. range 160-220‹ C.) obtained by conversion of carbon monoxide with hydrogen, and tetrahydronaphthalene over a catalyst at 430‹ C. and 20 atmospheres pressure, (B) petrolatum and crude benzol at. 430‹ C. and atmospheric pressure over a catalyst, and (C) a heavy benzine fraction of a paraffin basic mineral oil with crude benzol at 500‹ C. and 70 atmospheres through a heated tubular coil.

Title: Means for deriving the envelope of an audio frequency current, or the like
Filed: 1939-09-19
Abstract: 536,410. Automatic volume control. RADIO CORPORATION OF AMERICA. Sept. 19, 1939, No. 26185. Convention date, Oct. 29, 1938. [Class 40 (v)] In a circuit for obtaining across a condenser 7 the envelope of the peaks of a sound-recording current applied to the input 1, the discharge of the condenser 4 which is charged through the rectifier 3 is delayed, so that the voltage across the condenser 7 approaches more nearly to the required value. The delay is obtained in various ways. The discharge circuit can be constituted by a resistance 5, Fig. 4, and an inductance 14 shunted by a rectifier 17. The discharge through the resistance 5 may be into another condenser 20, Fig. 6, which has to discharge through a resistance 21. The discharge may actually be prevented by a valve 55, Fig.. 14, which is maintained non-conducting until the voltage across condenser 7 is substantially equal to that across condenser 4. The delay can also be obtained by impressing upon the rectifier 3 a succession of peaks obtained from each individual peak in the input, such as by using an " echo network Fig. 9 (not shown), or by a delay network 33, Fig. 10, bled at each stage of delay, or by parallel connection of a series of networks of progressive delay valves, Fig. 11 (not shown).

Patent GB-447531-A (GB)
Title: Improvements in or relating to the manufacture of cellulose esters
IPC: C08B3/22
Filed: 1935-09-24
Abstract: In a process for stabilizing organic esters of cellulose, the esters immediately after precipitation from the esterification solution are mixed with water insoluble salts of a basic character. Advantageously, the ester after precipitation is suspended or dissolved in a liquid, e.g. a lower aliphatic acid, especially acetic acid or an aqueous solution thereof, the basic salt, finely powdered, or a soluble salt which may be converted to the basic salt being mixed in with the ester.  Or the ester may be dissolved or suspended in an aqueous medium containing a salt which may yield the basic salt, by hydrolysis or by the action of a basic substance such as an alkali metal hydroxide or carbonate, e.g. sodium or potassium acetate, zinc chloride, aluminium chloride, tin chloride, lead chloride or mixtures of these.  The temperature at which the basic salt is mixed with the cellulose ester depends on the method of formation of the basic salt. Elevated temperatures, e.g. the boiling point are usually employed.  The amount of basic salt used is preferably theoretically equivalent to the amount of sulphur in the ester calculated as SO4.  Larger amounts reduce the viscosity of the ester and produce esters which are suitable for lacquers. Small amounts of inorganic salts such as aluminium chloride, zinc chloride and/or hydrochloric acid may be added to the ester during the ripening stage as described in Specification 446,723, and the esters may be treated with basic salts before precipitation as described in Specification 447,530.  The esters produced by this process have a high heat test, and their solutions are stable and have good filtration properties.  They are stable to light and acids, and may be employed for filaments of low denier.  In an example, 12 parts of precipitated unstabilized cellulose acetate are suspended in water containing 0,4 parts of aluminium chloride hexahydrate; after 20 minutes, 0,7 parts of sodium acetate is added, and the temperature raised to boiling point and kept there for 30 minutes; the ester is then washed several times. In another example, 120 grams of partially stabilized cellulose acetate is dissolved in 600 grams of glacial acetic acid at 99 DEG  C.; 40 c.cs. of a solution of zinc chloride in acetic acid are added; the solution is maintained at 99 DEG  C. for 30 minutes and then precipitated with water in small lumps which easily break to a powder.  In a third example, 120 parts of unstabilized cellulose acetate is dissolved in 600 parts of glacial acetic acid at 99 DEG  C., and 6 parts of zinc chloride and 6 parts of sodium acetate are added.  The solution is cooled and precipitated in a soft fibrous form with water.  The ester is washed.  In either of the last two examples, the ester could be suspended in an aqueous solution of the acid.
