Title: Improvements relating to lubricating greases
IPC: C10M/
Filed: 1958-03-05
Abstract: A lubricating grease comprises a lubricating oil thickened to a grease consistency with a metal alcoholate/carboxylate derived from a hydroxy fatty acid.  The lubricating oil may be a mineral oil while the thickening agent may have the formula (RCOO)x-nX(OH)n wherein R is a hydrocarbon radical having one or more substituents at least one of which is a metaloxy group, X is a soap-forming metal (e.g. an alkali or alkaline earth metal, magnesium or aluminium) or a soap-forming group (e.g. ammonium), x is the valency of X and n is 0 or a number smaller than x.  The grease consistency may be obtained by the use of a mixture of such metaloxy soaps or a mixture of metaloxy soaps and other soaps, e.g. hydroxy fatty acid soaps. The thickening agent may be prepared (1) by reacting a hydroxy fatty acid, or a soap thereof, with a metal or metal alcoholate or (2) by reacting an ester of a hydroxy fatty acid with a metal or metal alcoholate to form a metaloxy fatty acid ester and then saponifying the latter with a metal hydroxide.  In examples, hydrogenated castor oil is reacted with sodium, lithium or lithium ethoxide and the reaction product is saponified with lithium hydroxide in the presence of mineral lubricating oil.  In a further example, 12-hydroxy stearic acid is reacted with lithium and the reaction product is dissolved in mineral lubricating oil. For comparison purposes, the preparation of a conventional lithium 12-hydroxy stearate grease, by reacting 12-hydroxy stearic acid with lithium hydroxide with 12-hydroxy stearic acid in the presence of mineral lubricating oil, is described.

Abstract: 1,175,549. Delivering shields; endless conveyers. DEVELOPMENT & CONTROL Ltd., S.A. 14 Feb., 1967 [15 Feb., 1966], No. 7100/67. Headings B8A and B8R. General arrangement.-Newspapers fed in an overlapping stream between conveyers 16 and 18 are delivered in counted batches into receptacles 30 movable in an endless path on chain conveyer 42. Receptacles 30 are linked to chains 42 by limited-lost-motion connections and biased in the direction of movement of chains 42 by springs 94. A stop means 100 is engageable in turn with each receptacle 30 preceding the one receiving newspapers from belts 16 and 18 to restrain the receptacle against movement with the conveyer and then to restrain the conveyer whilst the preceding receptacle is being filled. Disengagement of stop 100 after a predetermined quantity of newspapers has been delivered, accelerates the restrained receptacle along the conveyer to intercept the stream cleanly. Receptacles 30 deliver the counted batches to roller conveyer 40. Receivers.-Each receptacle 30 comprises back 34 and supporting fingers 36 and is linked to chains 42 by blocks 82 slidable in channels 88 on rails 34. Pins 90 on rails 34 are slidable in slots 92 in blocks 82 to provide the limited-lostmotion connection. Receptacles 30 are guided by rollers 74 and 80 running in guideways 76 alongside the chains 42. Each receptacle may be arrested by roller stops 104 mounted on lever 106, and engageable with stops 122 on the receptacle. Spring 116 biases roller stops 104 into engagement with stops 122, the roller stops being retractable by means of solenoid 112. Chains 42 are driven through a slipping clutch by motor 54. Delivery in counted batches.-Newspapers are guided by curved members 102 on to the fingers 36 of each receptacle 30 as it moves downwardly on chains 42 below its arrested position, the preceding receptacle being restrained by stop means 100 causing pins 90 to travel to the top of slots 92 due to the continued movement of chains 42 and thus eventually stopping the conveyer. When a predetermined number of newspapers has been delivered as determined by counter 24, solenoid 112 is energized to release the succeeding receptacle which is accelerated by stretched spring 94 in the direction of conveyer movement, thus to intercept the stream. Fingers 36 pass between the rollers of conveyer 40 to deposit each stack 38 thereon.

Title: Purified laurolactam
Inventor: RAFF PAUL
IPC: C07D201/16
Filed: 1964-02-25
Abstract: Laurolactam, the lactam of o -amino-lauric acid, is recovered from solutions of laurolactam in mineral acids, from suspensions of laurolatam in acid, neutral or alkaline aqueous solutions, or from solutions of salts which also contain laurolactam in solution or suspension, by mixing the lactam-containing mixture with an organic solvent or solvent mixture as defined below, adding water if desired, separating the two layers which form, treating the solution of laurolactam in the organic solvent optionally with aqueous alkalis and then with water removing the extraction agent from the laurolactam by distillation, and then immediately distilling the lactam melt thus obtained under subatmospheric pressure to purify it. The organic solvent or solvent mixture is not miscible with water, boils at a temperature between 100 DEG  C. and 150 DEG  C. at atmospheric pressure, and forms stable homogeneous liquid binary mixtures with laurolactam in the temperature range above the boiling point of the solvent or solvent mixture up to the melting point of laurolactam.  Specified solvents are alkyl-substituted benzenes containing 7 or 8 carbon atoms, cycloalkanes or alkyl-substituted cycloalkanes containing 8 carbon atoms and 6- to 8-membered rings, and chlorinated hydrocarbons. Preferably, the extraction agent is removed from the laurolactam by a two-stage distillation, a liquid binary mixture containing preferably more than 50% by weight of laurolactam being obtained in the first stage, this mixture is, if desired, kept under protective conditions at a temperature in the range between 84 DEG  C. and 154 DEG  C., and the mixture is separated completely into laurolactam melt and extraction agent at a temperature above the melting point of laurolactam in the second distillation stage. When the initial material has been obtained via a Beckmann rearrangement it is preferred to add a neutralizing agent at the same time as the extraction agent.  Examples are given.
