Title: Antifriction elements of the graphitic type for bushes, packings, joints, washers and the like and method for manufacturing same
IPC: F16C33/16
Filed: 1946-09-10
Abstract: Antifriction parts such as brushes, packings, joints, and washers are manufactured by forming a compact agglomerate of carbonaceous material, stoving to convert the agglomerate entirely into artificial graphite, impregnating the graphite with a substance which, by polymerization or condensation, is capable of hardening, and treating the impregnated agglomerate to effect partial hardening of the impregnant which is left in a semi-plastic state.  Suitable impregnants are natural or artificial resins, oils, chlorinated aromatic compounds, or cellulose products.  The parts of lamp black, sugar charcoal, petroleum pitch or retort coke, coal, anthracite, or charcoal with a binder are graphitized by electric heating.  The parts may be given a prior impregnation, in an atmosphere of nitrogen, hydrogen, carbon monoxide, or illuminating gas, with a metal or a metal compound, e.g. (1) molten metal sulphides and/or selenides; (2) solutions of copper, lead, or silver salts which are subsequently transformed to sulphides or selenides by the action either of hydrogen sulphide or selenide or of solutions of polysulphides or polyselenides; or (3) a solution of an alkaline polysulphide or polysehenide followed by treatment with a metal or a metallic solution.  The parts are then washed, dried, impregnated with the condensable or polymerizable substance, heated to evaporate volatile matter, and further heated to modify the impregnant.  The Specification as open to inspection under Sect. 91 comprises also carrying out the two impregnations in reverse order or in combination; thus the part is impregnated: (a) with a solution of an alkali metal polysulphide in an alcohol-water mixture, a fatty acid having at least two sets of conjugated double bonds, and a metal soap, e.g. stearate or palmitate, when subsequent heating effects simultaneous sulphurizing and hardening; (b) with molten lead and a fatty siccative oil containing dissolved sulphur followed by heating to 180 DEG  C.; or (c) with a siccative oil containing a metal soap with treatment with hydrogen sulphide and/or selenide.  A further impregnation with sulphur or selenium in an organic solvent may be made.  The finished parts may have anti-oxidants incorporated therein and may be coated with lubricants.  This subject-matter does not appear in the Specification as accepted.

Patent GB-820535-A (GB)
Title: A new salt of phenoxymethyl-penicillin and its use for the isolation of said penicillin
IPC: C07D499/00
Filed: 1957-08-30
Abstract: The invention relates to the phenoxymethylpenicillinate of N,N-di-isopropyl-beta-hydroxy-ethylamine.  The salt is prepared by reacting the free base with the free acid in an organic solvent, or by reacting a salt of the base, e.g. the acetate, with a salt of the penicillin, e.g. potassium phenoxymethylpenicillin.  The salt is sparingly soluble in organic solvents such as n-butyl acetate, n-amyl acetate, ethyl acetate, acetone, methyl ethyl ketone and ether.  It is used in recovering phenoxymethylpenicillin from fermentation broths, the penicillin so recovered being substantially free from phenoxyacetic acid or beta-phenoxylactic acid (precursors used in the fermentation) and from benzyl penicillin.  The broth is acidified to solubilize the phenoxymethyl penicillin, e.g. by the addition of phosphoric acid to pH 2.0, extracted with n-butyl acetate or other organic solvent sparingly soluble in water, N,N-diisopropyl - beta - hydroxyethylamine added to the extract and the phenoxymethylpenicillinate of N,N - diisopropyl - beta - hydroxy - ethylamine crystals filtered off, washed with acetone and dried. Alternatively, the organic solvent extract is treated with an aqueous buffer, e.g. aqueous sodium phosphate of pH 6.5, and the aqueous extract so obtained is then extracted with the organic solvent and the base added to that extract.  The salt may be converted to other salts of phenoxymethylpenicillin; or may be converted to the free phenoxymethylpenicillin by treatment with strong acid in aqueous solution or suspension.

Abstract: 503,239. Automatic control systems. WOOLNOUGH. G.L., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Oct. 12, 1937, No. 27748. [Class 38 (iv)] Temperature.-In an electric furnace automatically controlled by an energy type regulator which supplies a constant but adjustable average energy to the furnace sufficient to cause a slow temperature increase a device responsive to furnace temperature changes the setting of the regulator so that the average energy supplied causes the temperature to fall slowly. Temperature fluctuations are thus minimized. The switch 4 controlling the circuit of heating elements 2 in a furnace 1 is operated by a winding 5 in series with the contacts 6 of a vacuum switch operated by a coil 7. The last is in series with the contacts 10 of an energy type regulator consisting of an enclosed thermal switch having a heating winding 12 connected across an adjustable portion of a potential divider 20, 13, 17. The contacts 6 when closed increase the heating of the coil 12 by putting a resistance 19 in parallel with the resistance 20, and so set up intermittent supply of current to the furnace. A temperature responsive element 1A in the furnace operates a switch 15 when a predetermined temperature has been attained and removes a short circuit about the adjustable element 17 and so reduces the setting of the energy regulator 9. A manual switch 16 is adapted to render the regulator 9 inoperative when starting up the furnace.
