Filed: 1972-04-10
Abstract: 1339090 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 10 April 1972 [9 June 1971] 16361/72 Heading G4A A data processing system having a plurality of I/O and/or auxiliary storage devices, such as tape units, is arranged to execute a plurality of tasks concurrently, to separately determine device utilization/loading due to tasks currently being executed and due to a task undergoing allocation, and to allocate a data set to a device on the basis of both determinations, e.g. to the device having the lowest utilization. The number of times an I/O supervisor is invoked to access data sets on the devices during the time interval between allocation of successive different tasks may be counted for each device currently being utilized. A task activity table may also be constructed to include an entry for each device to which a data set associated with a task is allocated, each entry including a count which is incremented whenever a data set allocated to that device is accessed.

Abstract: 529,679. Fluid-actuated valves. KENNEDY, J. E. June 6, 1939, No. 16581. [Class 135] Relates to valve-controlled nozzles for the discharge of a gaseous or vaporous pressure fluid, such as air or steam, along the inner surface of the wall of a container to aerate and discharge pulverulent, granular and like materials such as cement or flour from the container. The nozzle comprises a casing 5 secured at 7 in the container wall and having a tubular projecting outlet member 11 and is fitted with a valve stem 17 having heads 22, 19 at opposite ends, the head 19 seating on the end of the member 11 under the action of a spring 21 and being moved off its seat by the action of fluid pressure on the head 22.

Title: Oxazolidinone compounds and their preparation
IPC: C08G59/14
Filed: 1964-04-22
Abstract: Novel 2-oxazolidinones of the formula <FORM:1070581/C2/1> wherein Z11 is a polyvalent organic radical, Z0 is a polyvalent organic radical which contains at least one epoxy group, n is a whole number from 2-10 and G is oxygen or sulphur are made by dehydrohalogenating the appropriate poly(beta-haloalkylurethano)halohydrin.  Suitably, a bis urethane halohydrin of the formula HO.CH2.CHCl.C.HCl.CH2.O2C.NH.(CH2)6. NH.CO2.CH2.CHCl.CHCl.CH2.OH may be dehydrochlorinated to form 1,6-bis(4-oxiranyl - oxazolidin - 2 - one - 3 - yl) - hexane. In an example, tolylene diisocyanate is reacted with isopropylidene - bis(1 - phenoxy - 3 - chloropropan-2-ol) and the product is dehydrohalogenated to give a compound containing oxazolidinone and epoxide residues.ALSO:Substituted 2-oxazolidinone compounds of formula <FORM:1070581/C3/1> where Z11 is a polyvalent organic radical, Z0 is a polyvalent organic radical which contains at least one epoxy group, n is a whole number from 2 to 10 and G is oxygen or sulphur, are prepared by dehydrohalogenating a poly-(beta haloalkylurethano) halohydrin (A).  The compound (A) may be obtained by reacting an isocyanate, e.g. tolylene diisocyanate, hexamethylene diisocyanate, p,p1-diphenylmethane diisocyanate or an -NCO terminated prepolymer with a polyhalohydrin, e.g. polyepichlorhydrin and a polyalkylene glycol or trimethylol propane, or isopropylidene bis-[1 - (p - phenyleneoxy) - 3 - chloro - 2 - propanol]. Polymerizable compositions may be prepared by mixing the above compounds with an epoxy reactive comonomer which may be a polyol, polyfunctional amine, a polycarboxylic acid a polyanhydride or polyepoxide. The invention also comprises polymers containing two or more epoxy groups of epoxyoxazolidinane compounds containing only one epoxy group, e.g. the polymerization product of 3-allyl-5-epoxy ethyl-2-oxazolidinone. In Example (4) a polymer obtained by reaction of tolylene diisocyanate polypropylene glycol and isopropylidene bis - [1 - (p - phenyleneoxy) - 3 - chloro - 2 - propanol] was dehydrohalogenated with 10% NaOH and compounded with the following hardeners: (i) hexahydrophthalic anhydride, (ii) methylnadic anhydride, (iii) dodecenylsuccinic anhydride, (iv) diethylene triamine, (v) an epoxy adduct of diethylene triamine.  In Example (9) an epoxyoxazolidinone was used as a plasticizer for a 1/1 ethyl acrylate/methylmethacrylate polymer.  They may also plasticize polyvinylchloride, other vinyl halide resins and commercial epoxy resins. They may be used to cross-link acrylic polymers, e.g. a styrene/alkyl acrylate/methacrylic acid polymer or styrene/butadiene-acrylic acid polymer or vinyl acetate/acrylic acid polymer.

Abstract: 509,083. Extracting phenols. WITTEK, H. June 7, 1938, No. 16878. Convention date, June 5, 1937. [Class 91] [Also in Group IV] Phenols are extracted from tars, cracked tars or oils, or gas liquors by treating in the presence of water or other solvent for phenolates, with an alkaline earth metal oxide or oxides and magnesia. Low temperature tar, or crude tar oil is agitated at 40‹ to 50‹ C. with water or alcohol, and ground burnt dolomite. Magnesium oxide, silica and alumina settle out, and any iron oxide passes into the aqueous calcium phenolate layer. The aqueous layer is separated from the solid residue and hydrocarbon layer, and is worked up by heating in vacuum below 60‹ C. to remove neutral oils, distilling off the free phenol, acidifying the residue preferably with carbon dioxide, and further distilling ; or all the phenols may be liberated by acidification before distilling. The distillation may be effected in the presence of magnesium oxide sludge, and in a current of carbon dioxide, the aqueous phenol layer being pretreated with sulphur dioxide, whereby lighter coloured phenols are obtained. The magnesium oxide may be used to remove bases and unsaturated hydrocarbons from the hydrocarbon layer and neutral oil distillate, or these may be removed by sulphuric acid. Calcium carbonate and magnesium oxide sludges are mixed and burnt for further use.
