Title: Dialkylaminoalkyl-p-hydroxybenzoate salts of penicillin and their production
IPC: C07D499/24
Filed: 1950-03-22
Abstract: A penicillin salt having a protracted effect when injected into the blood stream of an animal, is obtained by mixing a solution of penicillin, or a salt thereof, with a solution of a dialkyl aminoalkyl-p-hydroxybenzoate, or a salt thereof, the alkyl groups of which are the same or different, and do not contain more than 4 carbon atoms.  The solution may be aqueous, in which case water-soluble salts are used, e.g. sodium and potassium penicillins and the hydrochloride or sulphate of the base. Alternatively, the penicillin or the dialkylaminoalkyl p-hydroxybenzoate, per se, may be dissolved in an organic solvent such as ether, methyl isobutyl ketone, amyl acetate, or a mixture of these with acetone, ethanol or other alcohols.  In the examples, a solution of the base or salt thereof is added to a solution of the penicillin or salt thereof and the mixture allowed to stand with cooling, if necessary.  The preferred salt is the diethylaminoethyl-p-hydroxybenzoate salt of benzyl penicillin, which crystallizes with one molecule of water of crystallization and has a melting-point of 89 DEG  to 90 DEG  C.  The formation of these salts may be used for the concentration and purification of penicillin from impure solutions.

Title: Manufacture of glycols and polyhydric alcohols
IPC: C07C31/20
Filed: 1940-05-02
Abstract: A polyhydric alcohol of higher molecular weight is prepared by eliminating halogen from a halogen derivative of a polyhydric alcohol of lower molecular weight, containing a free hydroxyl group, by the action of heat in the presence of finely-divided copper or silver prepared by reducing an aqueous copper or silver salt with sulphur dioxide.  Alcohols which may be used include the chlor-, or bromhydrins of ethylene, trimethylene or propylene glycols.  The process may be carried out as a batch or cascade process at temperatures above 100 DEG  C. in the presence of diluents or under pressure as desired.  Water is preferably absent from the reaction mixture, but a strong base may be present.  In an example, ethylene chlorhydrin is refluxed in the presence of monomethylamine and finely-divided copper obtained by the reduction with sulphur dioxide of an ammoniacal solution of copper sulphate acidified with acetic acid.  Tetramethylene glycol is separated from the reaction mixture by fractionation.

A straight pull impulse transmitter has a plastics belt, preferably polypropylene, with sections of reduced thickness for flexibility, and which is movable manually to a number of alternative setting positions by means of numbered finger stops carried on the upper exposed side of the belt, projections carried on its underside and positioned in correspondence with the finger stops operate, during the automatic restoring motion, an impulse mechanism a number of times dependent upon the setting position. The belt 11 meshes with a gear-wheel 18 and during the setting motion, as it is pulled from right to left, winds up a restoring spring 20, the nylon trigger 57 being rotated into a vertical position by the first projection a where it remains and is repeatedly depressed, as all projections pass over it, to cause the stud 50 on its supporting lever 47 to press the contact springs 44, 45 together and so self-wipe their contact points. The selected finger stop travels as far as X-X and upon the release and the return of the belt the trigger is rotated back, providing a lost motion period, and is successively depressed by the projections to open the impulse springs by lugs 57 as shown. In the home position-of the belt a stud 39 as on the gear-wheel 18 opens successively two contact pairs (33-34, 35-36, Fig. 1, not shown), one of which had been short-circuiting the receiver and the other of which is in series with the impulse contacts. The mark-space ratio is adjusted by means of an eccentrically mounted screw 56. The mechanism is enclosed within two casing-halves each having a groove in which an edge of the belt runs.
