Title: Manufacture and use of organic esters
IPC: C07C69/80
Filed: 1934-07-09
Abstract: Acylated acyclic formals are made by condensing acyclic formals of polyhydric alcohols with organic acids or their anhydrides or chlorides.  The acyclic formals may be made by condensing formaldehyde or paraformaldehyde with polyhydric alcohols such as diethylene glycol, triethylene glycol, or glycerol in the presence of an acid catalyst such as ferric chloride or other acid salt, or hydrochloric, sulphuric, phosphoric, or other mineral acid; and the organic acid may be an aromatic acid such as benzoic, phthalic, trimeric, naphthoic, or naphthenic acid.  When the organic acid is polybasic, the resulting ester may be cyclic; thus the condensation of phthalic anhydride with the acyclic formal of diethylene glycol yields a cyclic ester.  In an example, this ester is prepared by heating under reflux one molecular proportion of formaldehyde (as para-formaldehyde) and two molecular proportions of diethylene glycol in presence of sulphuric acid and distilling off the formal which is then heated with one molecular proportion of phthalic anhydride.  The formal esters are solvents, softening or plasticizing agents for cellulose acetate, nitrate, &c., and cellulose ethers, and may be employed to give plasticity or suppleness to coatings, films, textile materials, artificial masses, &c.  They may be used in spinning solutions for making artificial filaments, ribbons, films, foils, sheets &c. by dry or wet processes.  The spinning solution may contain other plasticizers or high-boiling solvents such as triacetin, dibenzyl, diethyl or dibutyl tartrate, the phthalate of the monomethyl ether of ethylene glycol, ethyl lactate, formal glycerol or diacetone alcohol, and low-boiling solvents such as acetone, methylene ethylene ether or methyl acetate.  The solutions may also be employed as dopes, varnishes and lacquers, for plastic sheets for laminated glass, and in the manufacture of plastics and moulding powders and articles made therefrom.  The compositions may contain any other ingredients, such as natural or synthetic resins, dyes, pigments, and fillers.

Filed: 1954-07-09
Abstract: <PICT:0760777/IV(b)/1> A process for the production of smooth 20 to 40 per cent protein slurries of improved colour comprises extracting vegetable globulin from groundnut meal with caustic soda solution having a concentration up to 0.1 per cent, acidifying the aqueous extract to between 4 and 5 with minimum turbulence if necessary raising the temperature and/or adding urea or ammonium sulphate and concentrating the mixture at pH about 5 in a continuously operated high-speed centrifugal machine.  As shown, the aqueous extract in tank 1 may be introduced from constant level tank 2 continuously and simultaneously with acid, e.g. aqueous 5-12 per cent hydrochloric acid solution, through pipe 8 in a quantity controlled by pH controller 9, into a residual bulk of liquor containing precipitated protein in tank 7 at pH 4 with minimum turbulence.  The pH of the liquor pumped forward to tank 14 is raised to 5.0 by addition of alkali prior to passage to high-speed nozzle discharge centrifuges. An aqueous extract containing ammonium sulphate or urea at raised temperature, e.g. 40 DEG  C. may be acidified directly to pH 5.0 in tank 7.  The acid may contain an agent suppressing the action of bacteria and enzymes, e.g. 1 per cent sulphur dioxide.  Specification 712,637 is referred to.

Title: Improvements relating to driving apparatus more particularly intended for intermittently operating apparatus for reproducing sound from a record
IPC: G11B19/265
Filed: 1936-07-22
Abstract: 478,595. Clutches for starting and stopping rotation. BRITISH THOMSONHOUSTON CO., Ltd., HALL, E. S., and BOWEN, A. July 22, 1936, No. 20340. [Class 80 (ii)] [Also in Group XXXVIII] Relates to mechanism for intermittently clutching a normally stationary rotatable member, such as a gramophone record 4, to a continuously rotating driving member 1, the rotatable member being given a starting rotation to permit of smooth clutching with the driving member. The invention particularly relates to such mechanism in which a spring-biassed pawl 3 pivoted on the rotatable member is normally held out of engagement with teeth 2 on the driving member by a bell-crank lever 7 pivoted on a fixed bracket and moved to start the rotation bv means such as an electric contactor 13. According to the invention, the tail of the pawl is engaged by a second bell-crank lever 9, pivotally mounted on the first, to keep the pawl engaged with the part 8 of the first lever and prevent clutching, the starting movement of the first lever acting through the second lever to impart the initial rotation to the rotatable member through the medium of the pawl. Further movement of the first lever causes the second lever to engage a stop 14 whereupon the pawl is released to engage the driving member. On release of the contactor 13, and after one or more revolutions of the rotatable member, the tail of the pawl engages the lever 9 and is brought out of engagement with the driving member and back into engagement with the lever 7.

Title: Improvements in transfer device for continuous spoolers
IPC: B65H67/056
Filed: 1961-06-06
Abstract: 963,749. Spooling wire. SYNCRO MACHINE CO. June 6, 1961 [March 14, 1961], No. 20408/61. Heading D1J. The invention relates to continuous wire spooling machines of the kind comprising two axially aligned spool shafts 12, 14, Fig. 1, separately driven such that when one spool S1 is filled the take-up speed of the core of the other spool S2 is made equal to that of the wire being wound on to the filled spool S1. According to the invention coil supporting assemblies 22, 26, 28 and 122, 126, 128 are detachably secured to the opposed ends of the shafts 12, 14 respectively, each assembly including a ring 28 (128) having substantially the same external diameter as the cores of the spools to be used therewith and on to which the initial end of the wire is first wound as a tail winding before being wound on a spool, there being a plurality of individual curved radially extending arms 42 (142) mounted on each of said assemblies, each of said arms including a guiding edge 42a Fig. 2 extending from said ring to the outermost portion of said arm for guiding the wire on to said rings respectively. In operation, when the spool S1, for example, is full the wire is first transferred to the ring 128 associated with the spool S2 in order that an initial tail winding can be formed on the ring 128 and the wire is then transferred to the spool S2. Since the diameter of the ring 128 is the same diameter as the core of the spool S2 the wire is not, during transfer, subjected to any stresses that are sufficient to cause a reduction in its diameter. Each shaft has threaded therein a nut 34 carrying a disc 30 from which the curved arms 42 (142) extend. To remove a filled spool from its shaft the nut 34 is unscrewed and the supporting assemblies 22, 26, 28 removed. When the nut 34 is screwed into position projecting lugs 12a on the shaft 12 extend into corresponding openings 44 in the disc 30 on the nut 34 so that the shaft 12 can drive the disc 30. Specification 691,991 is referred to.

Abstract: 388,294. Discharging ashes from furnaces. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.-(Assignees of Foresman, R. A. ; 1010, 13th Avenue, Moore, Pennsylvania, U.S.A.) July 21, 1932, No. 20604. Convention date, July 27, 1931. [Class 51 (i).] Ashes from combustion chamber of a furnace pass into a water-filled pit 15, Fig. 8a, from which they are discharged by the aid of jets of water issuing from pipes 21, 22 into the valve controlled conduit 20 which is provided with an ejector 43 supplied with water by a valve controlled pipe 48. The discharge of the pit may be effected at intervals by hand control or automatic control in accordance with the level of ashes in the pit, the water supply valves 49, 37 and the ash-discharge valve 38 being opened in sequence in the order named and subsequently closed in sequence after the pit has been emptied first by closing valve 38, then the valve 49 and lastly the valve 37. When the ashes in the pit accumulate to a predetermined level ash-contacting members 83 operate a shaft 80 to close a switch 98 and supply current through an electric controller to a motor 131, Fig. 8, which drives through gearing the controller 138 and a pressure fluid distributing valve 70. The electric contacts on the controller are such that a step-by-step movement is imparted to the valve 70 in accordance with the desired sequence of movements of the fluid control valves. Rotation of the valve 70 first permits pressure fluid to pass from the main 48 to a servo motor 67 to open the valve 49 and permit pressure fluid to pass to the ejector 43 in the discharge conduit 39. Further rotation of the valve 70 effects the opening of the valve 37 by a servo motor 61 to permit pressure fluid to pass to the ashpit and subsequent rotation of the valve effects opening of the valve 38 in the discharge conduit 20 by the servomotor 64. The control circuit includes a thermal switch which allows the motor 131 and valve 70 to stop for a predetermined interval during the discharge of water and ashes from the pit after which the thermal switch closes and the motor is again operated to effect closing of the discharge valves, the valve 38 being closed first and subsequently the valves 49, 37 controlling the supply of fluid to the ejecter 43 and ashpit. The control circuits include lamps which indicate the various stages of the operations. Also float controlled switches are provided to ensure that the water in the pit does not rise above a predetermined level. If desired the electric controller may be operated by a hand lever 230 and shaft 231 through gearing, clutch mechanism being provided in the shaft 231 to connect or disconnect the motor or hand gear as desired. Specification 348,925 is referred to.

Title: Lubricating oil additive
Inventor: DAVIES ROY TREVOR
IPC: C10M169/00
Filed: 1951-08-31
Abstract: A solution of a divalent metal alkyl phenate or thiophenate in an inert solvent is reacted with elemental sulphur to give a complex reaction product as a concentrate in the inert solvent, and a proportion of a metal, ammonium or organic base salt of a petroleum mahogany acid is added to the concentrate.  The final concentrate is useful as a detergent additive for lubricating oils and, as a result of the presence of the mahogany sulphonate, shows no tendency to deposit crystals on standing; in the absence of the mahogany sulphonate there is a tendency for the deposition of crystals of alkyl phenol or thiophenol, which is probably partially regenerated during the sulphurization reaction.  The inert solvent may be lubricating oil and may contain a C8-C20 saturated aliphatic alcohol such as cetyl or stearyl alcohol to reduce foaming during the sulphurization reaction and to act as solubilizer of the sulphurized product. The divalent metal alkyl phenate or thiophenate may be an alkaline earth metal salt which may be a basic salt; similarly, the mahogany sulphonate may be an alkaline earth metal salt which may be a basic salt.  The magnesium salts of both the alkyl phenol or thiophenol and the mahogany acid are also mentioned.  The sulphurized product may be blown with carbon dioxide before or after the addition of the mahogany sulphonate.  In an example, barium p-tert. octyl phenate, in mineral lubricating oil solution containing a mixture of cetyl and stearyl alcohols, is sulphurized and calcium mahogany sulphonate is then added. Specifications 586,841, 599,729 and 600,825 are referred to.
