Filed: 1919-02-15
Abstract: 138,707. Arrol & Co., Sir W., and Shepherd, R. G. Feb. 15, 1919. Overwinding and overrunning, preventing.- Overloading and over-racking of cranes and hoisting machines is prevented bv means of two sets of switches, one set being operated by the weight of the load, the other set being dependent on the radial distance of the load. The hoisting-rope c is attached to a spring or other buffer d which opens " overload " switches g<1>, g<2>, g<3>, in turn as the load increases. These switches are in the circuit of the " no-volt " coil containing other switches o<1>, o<2>, which are automatically opened as the load reaches pre-determined radii. When this circuit is broken the " no-volt " coil breaks the main circuit and applies the magnetic brake. Thus the switch g' limits the load which can be dealt with at any radius, and the switches o<1>, o<2>, determine the radii at which the loads which operate the switches g<1>, g<2>, respectively can be handled. Limit switches m, n, are opened at the extreme traverse of the load. The radius or position switches, m, n, o<1>, o<2>, are operated by a screwed shaft geared to the winding-drum.

Abstract: <PICT:0744373/III/1> In a continuous process for the removal of oxygen or hydrogen from admixture with an inert gas or gas mixture, e.g. nitrogen, argon, krypton, helium, neon or mixtures thereof, by adding to the crude gas mixture flowing at a constant rate an approximately stoichiometric amount of hydrogen or oxygen and then converting the hydrogen and oxygen present to water, the crude gas mixture prior to the hydrogen or oxygen addition being diluted with an amount of the purified gas resulting from the process such that the impurity content of the resulting gas mixture flowing at the constant rate is maintained stoichiometrically equivalent to the hydrogen or oxygen added, and the dilution of of the crude gas mixture with the purified gas is controlled automatically by the oxygen or hydrogen content of the purified gas.  Crude gas passes through pipe 1, blower 2 and pipe 3, and after admixture of hydrogen or oxygen from 4, enters purifier 5.  Purified gas leaves through lines 6 and 7, and is analysed by oxygen/hydrogen detector 8.  The impulses from detector 8 are received by controller 9, which operates valve 10 in by-pass line 11 to in crease the flow of recycle gas to pipe 1, if the impurity of the crude gas is in excess on analysis. If the recycle flow becomes excessive, then flow controller 12 with automatically open valve 13 to increase the hydrogen or oxygen addition.  If the impurity concentration falls then valves 10 and 13 will be closed by operation of detector 8 and flow controller 12.  To remove any temporary excess of hydrogen or oxygen the purified gas may, after analysis, be passed through an oxidisable and reducible mass, e.g. mixtures of copper/copper oxide or mixtures of manganese oxides which may be on kieselguhr, silica, or alumina gel supports.

Abstract: Alkanoic acid amides are made by heating in an aqueous solution an alkene-sulphur oil (Cn H2n + 1)2 Sx, where x is at least 3, with ammonia, an aliphatic primary or secondary amine, at 175-350, preferably 240-270 DEG C.  Oils of average composition between(Cn H2n + 1)2S3 and (Cn H2n + 1)2S8 are treated with ammonia and water at 240-270 DEG C. (Cn H2n + 1)2S5 is the preferred average composition for the oil.  An excess of water and ammonia or amine is preferred usually 3 mols. of water and about 5 mols. of ammonia per mol. of oil are used.  Amines specified are methyl-, ethyl-, propyl-and butyl-amines.  The oils may be made by treating an alkene with sulphur at 160-250, preferably 190-210 DEG C., the reaction being hastened by the addition of about 1 mol. of hydrogen sulphide per 2 mols. of alkene, or the alkene may be treated with sulphur dioxide and hydrogen sulphide at similar temperatures in the presence of about 1-5 per cent. of an aliphatic tertiary amine, or cobalt, nickel, zinc or manganese sulphide using about 2 mols. of the sulphide and at least about 0.6-0.7 mols. of the dioxide per mol. of alkene.  Propylene and isobutylene give particularly advantageous results other olefines mentioned being ethylene, n-butenes, pentenes, hexenes, 3,5, 5-trimethyl-hexenes, dodecenes and octadecenes.  The oils may be formed in an aqueous medium or under anhydrous conditions in a solvent such as dioxane, pyridine or benzene.  Reactions are carried out in a closed system under pressure.
