Abstract: 597,651. Continuous casting-machines. ANDREWS, H., and JAMES & CO. (BIRMINGHAM), Ltd. April 24, 1945, No. 10289. [Class 83 (i)] Moulds.-A method of producing continuous cast-iron sections consists in drawing the casting intermittently from a graphite die to the inner end of which molten iron is fed from a reservoir, applying heat to the inner end of the die to maintain the iron therein molten, and applying a cooling medium to the outer part of the die so as to cool the iron through the solidification point at the desired rate to give the casting the required physical properties. Molten metal from a melting pot 10 passes through a carbon or other block 13 into the die 16 which is heated at its inner end by burners 17 and cooled by water jackets 18 and 19 towards its outer end. Pyrometers 23 and an indicator 24 facilitate temperature control. As the metal in the die cools to form a solid casting ; it is withdrawn intermittently by means of reciprocating grippers acting on the previously cast material. The grippers are actuated by levers from a disc driven at a constant speed and connected to a reciprocating slide by a connecting rod. The point at which the connecting-rod is pivoted to the disc may be adjusted to and from the axis so as to vary the rate of feed. Specifications 168,648, [Class 83 (i)], 496,151, 540,276, 561,363 and 588,618 are referred to.

An anti-tumour preparation containing the cells of Streptococcus hemolyticus having no virulence and no hemolytic activity but having anti-tumour activity is prepared by mixing penicillin and living cells of Streptococcus hemolyticus having anti-tumour activity in a suspension medium comprising an aqueous solution of salts, the amount of penicillin being such that the concentration of penicillin in the suspension medium exceeds 25,000 units per ml. of the total liquid in said mixture, and incubating the resulting mixture firstly at a temperature in the range of 30‹C to 38‹C and then at a temperature in the range of 38‹C to 50‹C so as to obtain the desired antitumour preparation in which the majority of the Streptococcus hemolyticus cells are dead. The first stage of incubation may be effected for 10 to 30 minutes and the second for 20 to 60 minutes. The concentration of penicillin in the suspension medium may be from 27,000 to 60,000 units/ml of the total liquid in the mixture. The suspension medium may be phosphate buffered saline or Bernheimer's basul medium composed of maltose, KH 2 PO 4 , MgSO 4 .7H 2 O, distilled water and having a pH of from 6.8 to 7.0. The cells of Streptococcus hemolyticus may be obtained by cultivating Streptococcus hemolyticus in a cultivating medium in which the main carbon source is one other than glucose e.g. meat infusion broth or a medium containing ribonucleic acid and/or ribonuclease core each present in an amount of from 0.5 to 1.0% w/v. Penicillin may be added to the suspension medium prior to or after suspension of Streptococcus hemolyticus cells therein. The resulting suspension of cocci may be aseptically diluted with a salt solution, preferably containing penicillin to obtain a form suitable for therapeutic administration e.g. injection.

Abstract: 454,582. Fluid - pressure engines. LUCAS, Ltd., J., and WATSON, E. A., Great King Street, Birmingham. April 4, 1935, Nos. 10456 and 27957. [Class 122 (iii)] [See also Groups XXVIII and XXXIV] A device for supplying a charge of lubricating oil to the cylinders of an internalcombustion engine when starting from cold comprises a chamber provided with inlet and outlet connections and appropriate valves, means responsive to the heat of the engine whereby oil can be displaced from the chamber to the engine cylinders or parts communicating therewith and can be automatically replenished when the engine temperature falls, and supplementary means for supplying a quantity of oil to the engine under the action of the pressure in the normal engine lubricating system. The chamber a, Fig. 2, the inlet and outlet of which are provided with ball valves d, contains a metal bellows e containing a readily volatilizable liquid ; on receiving heat from the engine exhaust pipe or cylinder cooling water, the bellows expands and forces oil to the cylinders either directly or through the fuel induction pipe ; on cooling, the bellows contracts and fresh oil is drawn into the chamber. A ball f closes the port g when the bellows is fully expanded. A cylinder h communicates at j with the chamber a and contains a diaphragm or piston i urged upwardly by a spring k ; on starting the engine, the oil in the normal lubricating system moves the piston downwardly, forcing a charge of lubricant out through the outlet c. In a modification, Fig. 5, the piston i is replaced by a bellows n, the interior of which communicates with the normal lubricating system. The two chambers communicate through a non-return valve s.

Title: Novel dibasic aromatic acids and derivatives thereof
IPC: C07C63/331
Filed: 1954-04-09
Abstract: The dimethyl esters of 2 : 2-bis-(m- or p-carboxyphenyl) propane (see Group IV (b)) are converted into ethylene glycol polyesters.  Thus the ester of the p,p1 compound is heated with litharge and excess ethylene glycol in the presence of nitrogen until most of the methanol is removed, followed by removal of most of the excess ethylene glycol, polymerization being continued for several hours by heating under vacuum.  The 2 : 2-bis-(m- or p-carboxyphenyl) propanes (see Group IV (b)) form polyamides with, for example, hexamethylenediamine.ALSO:The invention comprises the compounds 2:2-bis - (p - carboxyphenyl) propane, 2:2 - bis-(m-carboxyphenyl) propane and the dimethyl esters thereof.  Three methods of production are described: (1) a mixture of 2:2-ditolyl propanes is oxidized by heating with aqueous nitric acid in the presence of ammonium vanadate to give a mixture of 2:2-bis-(carboxyphenyl) propanes pure 2:2-bis-(m-carboxyphenyl) propane being obtained therefrom by fractional crystallization; (2) aniline and acetone are reacted in the presence of hydrochloric acid to give 2:2-bis-(p-aminophenyl) propane, the amino groups of which are replaced by cyano groups by the Sandmeyer process, and the 2:2-bis-(p-cyanophenyl) propane is hydrolysed with aqueous sulphuric acid to give 2:2-bis-(p-carboxyphenyl) propane; (3) 2:2-diphenylpropane is acylated using acetyl chloride in the presence of aluminium chloride and the resultant 2:2-bis-(p-acetylphenyl) propane is oxidized with sodium hypochlorite to give 2:2-bis-(p-carboxyphenyl) propane.  The dimethyl esters are obtained by dissolving the acids in methanol, saturating the solution with dry hydrogen chloride and refluxing. Alternatively the mixture of acids obtained in (1) is esterified with methanol and the esters separated.  Other methylating agents specified are methyl hydrogen sulphate, dimethyl sulphate and diazomethane.  The compounds are used to prepare polyesters and polyamides (see Group IV (a)).  2:2-Ditolylpropanes are prepared by reacting toluene in the presence of aluminium chloride with 2:2-dichloropropane (obtained by reaction between acetone and phosphorus pentachloride).  2:2-Di-(p-tolyl)propane is prepared by reaction between toluene and p-methyl-alphamethyl styrene in the presence of a sulphuric acid-mercuric sulphate catalyst. 2:2-Diphenylpropane is prepared by reacting benzene in the presence of aluminium chloride with 2:2-dichloropropane. 2:2-bis-(p-hydroxymethylphenyl) propane is prepared by reduction of the dimethyl ester of 2:2-bis-(p,carboxyphenyl) propane with lithium aluminium hydride in anhydrous diethyl ether.  The dihydroxy compound dissolved in chloroform and the solution saturated with hydrogen chloride gave, after drying over calcium sulphate and removal of chloroform under reduced pressure, 2:2-bis-(p-chlorophenyl) propane.
