Title: Process for dry-cleaning fibrous materials and preparations therefor
IPC: D06L1/04
Filed: 1955-01-19
Abstract: A dry-cleaning composition for fibrous materials comprises a dry-cleaning solvent containing (1) a carboxylic acid amide of at least 12 carbon atoms, which may be substituted in the amide group by an alkyl, hydroxyalkyl or polyglycol ether group, and/or a salt of an imino-ether containing at least 12 carbon atoms, and (2) an oxyethylated compound.  Optional additions include water or additions of the kind used in dry-cleaning liquors.  The solvents specified are carbon tetrachloride, trichlorethylene, perchlorethylene and benzine. An exemplified amide is oleic acid ethanolamide, and a suitable imino-ether is that of coconut oil fatty acid ethanolamide.  The salt of the iminoether and the amide may be added together to the dry-cleaning solvent by incorporating therein a mixture of the salt and amide such as is obtained by reacting one molecular proportion of a carboxylic acid amide, containing at least one hydrogen atom bound to the amide group, with less than one molecular proportion of a dialkyl sulphate.  The oxyethylated compounds may be condensation products of ethylene oxide with compounds of high molecular weight containing a hydroxyl or amino group, such as oxyethylated fatty alcohols, oxyethylated fatty acids, oxyethylated alkyl phenols, oxyethylated fatty amines and oxyethylated fatty acid amides. Compounds exemplified are nonylphenol polyglycol ether containing 5 ethylene oxide groups per mol., and dodecyl-phenol polyglycol ether containing 5 ethylene oxide groups per mol.  Concentrated preparations may be prepared, in the form of solutions, suspensions or pastes, for addition to the drycleaning solvents.

Title: Process for the isotopic enrichment of lithium by chemical exchange
Inventor: SAITO EICHI
IPC: C01D15/00
Filed: 1960-01-19
Abstract: In a process for the isotopic enrichment of <PICT:0902755/III/1> lithium by exchange between Li amalgam contacted with an aqueous solution of an ionized Li compound, the influence of the side reaction between the water of the solution and the Li of the amalgam, which leads to decomposition of the latter, is rendered negligible by applying a potential difference between the amalgam and solution in the contact apparatus to inhibit such side reaction.  Alternatively, the potential difference is applied between the amalgam and solution in a separate contact apparatus from the exchange contact apparatus, and partial decomposition of the amalgam is allowed in the exchange contact, with regeneration of the decomposed amalgam fraction by the p.d. application.  In the process, 6Li concentrates in the amalgam and 7Li in the solution.  Li compounds may be hydroxide, halides, e.g. chloride, sulphate, or nitrate.  The circulation of contacting amalgam and solution may be coupled by converting the Li in the amalgam leaving the contact apparatus to the ionized lithium compound in solution, and converting leaving solution to amalgam. The amalgam leaving countercurrent contact apparatus 24, in which a p.d. is applied, passes through packed amalgam decomposition column 18 countercurrent to water from 34.  The resulting LiOH solution from the top of the column 18 passes through 24, and evaporator 13, to electrolyser 14 supplied with mercury from column 18.  The resulting amalgam is passed to 24 and steam from 13, 14 is condensed at 32 and returned to 18.  Fresh solution is fed in at 31 and enriched products are withdrawn at 28, 30, whereby such units may be connected in cascades.

Title: Improvements relating to speed control arrangements for multiple motor drives
Inventor: DOBRICH HEINZ
IPC: H02P5/50
Filed: 1961-01-19
Abstract: 908,921. Control of A.C. motors. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Jan. 19, 1961, No. 2225/61. Class 38 (3). In a multi-unit rolling mill for steel strip, plastics or paper, to establish desired differences in speed between successive stands 1, 2, the speed of each stand is adjusted as it first receives the strip 5 in accordance with the motor armature current of the preceding one. When the strip reaches a switch 6, a relay 6<SP>1</SP> closes contacts 6<SP>11</SP> momentarily so that the value of the current in the first armature 31, measured by a device 39, may be stored in a device 40. As the strip enters the rolls 2, if they are not running at exactly the correct speed, the resulting tension or compression in the strip changes the current in armature 31. This new value is signalled to a comparator 42, through contacts 7<SP>11</SP> (which close as the strip reaches a switch 7), where the difference between the new and the stored current value is used to control a generator 38 supplying the field 36 of the second stand's motor. The speed of the rolls 2 is thus adjusted, either until the current in armature 31 is restored to its original value, when the strip between the rolls will experience neither tension nor compression, or until this strip is loaded by a predetermined amount which is obtained by biasing the store 40 by a device 41; alternatively, the comparator 42 may have a predetermined zone of insensitivity. Contacts 7<SP>11</SP> re-open when the desired condition is reached. The arrangement may be applied to any number of successive stands, e.g. third rolls would be controlled by the current in armature 32. The switches 6 and 7 are spaced to avoid operation while the armature currents are unstable. The overall speed of the mill is varied by altering the voltage on bus-bars 33, 34, and the speed of each motor may be kept at the set value by tacho-generator feedback, in which case the output of comparator 42 would adjust a reference voltage. It is stated that the speed of a number of loaded stands may be further adjusted by a subsequent stand; e.g. prescribed current differentials may be established.
