A guide wall 20 extends from one edge of the table 18 and the sheets are urged towards the wall by the roller 66 whose plane of rotation is inclined slightly towards the wall. To prevent buckling of the sheets, they are fed across the table under a plate 74 having an upwardly inclined portion 74a, suitable openings being provided in the table 18 and plate 74 for operation of the various rollers. The upper rollers 66, 106 are mounted on lever arms 69, 110 respectively which are urged by springs 70, 114 towards the lower rollers. The tape 38 is fed from a roll 39 via a roller 180 to the tape applying head 36, and passes through the head over a grooved roller 137, Fig. 18 and out through a lower mouth portion 158. The head 36 is mounted on an arm 143, Fig. 2 fixed to the enlarged end 145 of a shaft 147 rotation of which is effected by solenoids controlled by micro-switches located in the path of the sheets, this rotation in one direction or another serving to raise or lower the head 36. The tape cutter 41<SP>1</SP> is controlled by a solenoid 222 having an armature assembly 224 spring loaded in an upward direction by a spring 226. The control arms 241c, 241d, 241a, 241b, Fig. 12 of four microswitches project through an opening 104<SP>1</SP> in the table 18 and are operated in sequence by passage of the sheets. The arrangement is such that the sequential depression of the control arms energize circuits for lowering the tape applying head 36 by rotation of the shaft 147 to bring the end of the tape into contact with the sheet, raising the head 36 and simultaneously lowering the tape cutter 41<SP>1</SP> and subsequently raising the tape cutter. The tape cutter is operated when the trailing edge of a sheet passes over the control arm 241c, this arm being positioned so that the tape cutter operates at such an instant of time that the end of the portion of the tape which is severed will just reach the trailing edge of the sheet when applied thereto by the tape applying rollers 106, 77.

Title: Improvements in or relating to insoluble salt of penicillin and process of preparing the same
IPC: C07D499/00
Filed: 1949-08-23
Abstract: The 2-chloroprocaine (diethylaminoethyl 2-chloro - 4 - aminobenzoate) salt of penicillin (especially penicillin G) is manufactured by bringing together penicillin and 2-chloroprocaine in a solvent in which 2-chloroprocaine penicillin is relatively insoluble, with the 2-chloroprocaine and penicillin in solution in amounts to form substantially more 2-chloroprocaine penicillin than will dissolve in the solvent, and separating the resulting precipitate.  The process may be effected by reacting in aqueous solution a metallic or metallic-like salt of penicillin with a 2-chloroprocaine salt, or by reacting penicillin (acid) with 2-chloroprocaine (base).  The process is applicable to the purification of penicillin by precipitating its 2-chloroprocaine salt from solution, separating the precipitate and recovering penicillin from the salt, e.g. by dissolving the salt in an aqueous medium of pH not exceeding 2 and extracting with a water-immiscible penicillin solvent.  Examples describe the interaction of: (1) pure penicillin G and 2-chloroprocaine in amyl acetate; (2) a crude mixture of penicillin G with some F, dihydro F and K and 2-chloroprocaine in amyl acetate; (3) pure potassium penicillin G and 2-chloroprocaine hydrochloride in water; (4) an impure mixture of the sodium salts of penicillins G, F, dihydro F and K and 2-chloroprocaine sulphate in water.  2-Chloroprocaine is prepared in the form of its hydrochloride by treating 2-chloro-4-nitrobenzoic acid with thionyl chloride, refluxing the resulting acid chloride with b -diethylaminoethanol in benzene, and then reducing the nitro group with hydrogen in the presence of Adams platinum oxide catalyst in aqueous solution.
