Title: Improvements in or relating to the purification of penicillin salts
IPC: C07D499/00
Filed: 1948-12-31
Abstract: Penicillin is purified by treating penicillin or a salt of penicillin with procaine or a salt of procaine in solution in a solvent in which procaine penicillin is substantially insoluble, separating the precipitated procaine penicillin and suspending it in a mixture of water and a substantially water-immiscible organic solvent, hydrolyzing the procaine penicillin under acid conditions or under alkaline conditions at or below room temperature, extracting the liberated penicillin into the organic solvent and recovering therefrom the purified penicillin.  As solvent there may be used butyl alcohol, amyl alcohol, methyl isobutyl ketone, butyl acetate, amyl acetate and chloroform.  Detailed examples are given. Specification 607,004 is referred to.
Patent GB-483810-A (GB)
Title: Improvements in or relating to processes for the manufacture of artificial textile fibres
IPC: D01F4/00
Filed: 1936-08-21
Abstract: Artificial wool, cotton, &c. which have been made by coagulating solutions of casein alone or mixed with viscose, are rendered insoluble by adding to the known formaldehyde bath a quantity of sodium chloride sufficient to prevent swelling of the fibres. Aluminium salts and acid may also be added.  It is preferred to treat the fibres with formaldehyde-sodium chloride baths of increasing concentration with respect to formaldehyde, in particular first to render the fibres partly insoluble by treatment under tension with a bath of low concentration, and after cutting the fibres to the desired length, subjecting them to treatment with baths of higher concentrations in order to cause twisting of the fibres. Specifications 483,731, 483,807, 483,808, and 483,809 are referred to.

Abstract: 777,492. Railway track packing machines. WITTGENSTEIN, G. F. Nov. 22, 1954 [Dec. 5, 1953], No. 33755/54. Class 104 (2). In a railway track packing machine provided with vertically movable packing mechanisms having a pair of pivot members 6 movable towards and away from each other, a pair of jaws 5, 51 arranged one on each side of the sleeper 1 and mounted on the pivot members 6 and a continuously rotatable shaft 13 on which is fixed a rotary member 14, the rotary member 14 is provided with at least two opposite protuberances 15, 151 which engage the upper end of the jaws 5, 5<SP>1</SP> to force them apart so as to intermittently force the tools towards one another to pack the ballast beneath the sleeper 1. The members 6 are screwed and mounted on an oppositely threaded shaft 8 rotated by a worm 9 and wheel 10. Alternatively the members 6 may be moved by a cable and winch in which case a wedge or the like should be provided to prevent recoil along a slideway on which the members 6 move. Two straps 16 articulated about the shaft 13 have elongated openings for the passage of roller pins 11 to allow sufficient movement thereof. Rollers 18 can be held against the member 14 by tension springs 20, Fig. 2, attached at one end to the jaws 5 or 51 and at the other end to a collar 19 loosely mounted on the shaft 13. The jaws 5, 51 may alternatively be directly connected by a spring. In a modification the rollers 18 are held against the member 14 by keying or otherwise securing the jaws 5, 5<SP>1</SP> to the pivot 7 which thus serve as torsion bars. The upper ends of the jaws 5, 51 may be moved outwardly by light springs. The relationship between the length of the jaws 5, 51 position of the pivots 7, the height and circumferential length of the protuberances 15, 15<SP>1</SP>, the speed of advance of the pivot members 6 and the angular velocity of the shaft 13 are such that the speed of the shoes 12 increases from the beginning to the end of the impact stroke on the ballast 3. The protuberances 15, 15<SP>1</SP> may be detachably secured to the member 14. The movement of the pivots 6 towards one another is in practice discontinuous and intermittent by reason of the different powers of the motors for the shaft 13 for the impact stroke and for the worm 10 for the follow-up. Specifications 403,256, 406,064 and 424,549 are referred to.

Abstract: 862,938. Winding tyre bead cores. NATIONAL-STANDARD CO. Oct. 19, 1959 [Nov. 24, 1958], No. 35340/59. Class 144 (1). A tyre bead core winding machine comprises a guide-mechanism 11 reciprocable by a motor 44 transversely of a former 4 to control the winding of the bead core wire 10 in successive turns in the former groove 9, the motor 44 being controlled by a device 28 which is actuated by a timing means 50 driven in synchronism with the former 4. As shown, the guide mechanism comprises a guide pulley 14 mounted on a reciprocable shaft 13 to feed the bead wire 10 to a laying pulley 15 which is carried by an arm 17 of a bell-crank 18 pivotally carried by the shaft 13. The shaft 13 is reciprocated through a crank 66 by a double-acting hydraulic motor 44, the cylinder 43 of which is fed with fluid selectively on either side of the piston 45 through a change-over valve 28. The valve 28 is supplied with fluid from a reservoir 23 by a variable volume pump 20 which is driven by the former drive-motor 6, exhaust fluid from the cylinder 43 being passed back to the reservoir through the valve 28. Actuation of the valve 28 to effect changeover of the cylinder feed, and thereby reciprocation of the piston 45 operating the crank 66, is effected by the alternate energization of two solenoids 37, 38 connected to the valve 28. The solenoids 37, 38 are respectively energized from a secondary supply 108 through micro-switches 62, 63 disposed for actuation by respective series of lugs 60, 61 carried at desired spacing by an endless chain 55 driven around pulleys 56, 57, 58 through a reduction gear 59 from the drive-motor 6. The spacing and number of the switches 60, 61 determines the number of convolutions per layer and number of layers respectively making up the cross-section of the bead core. On completion of the bead core winding, a lug 73 on the chain 55 opens a microswitch 72 to de-energize a relay 112 controlling the drive-motor circuit and thereby stop the motor 6 and thus the fluid pump 20 and the chain 55. Normally closed contacts 116 of the relay 112 are thereby allowed to close a circuit to a solenoid 71 which opens a valve 74 to place the ends of cylinder 43 in communication with each other. A pneumatic motor 80 is then actuated to move a pair of abutments 86, 87 against the crank 66 to align the crank so that the shaft 13 is reset to the start position for the next winding operation. At the same time a further abutment 85 is moved by the motor 80 to operate a bell-crank linkage 92, 94, 97 to effect raising of the laying pulley 15 from the former 4 for removal of the wound bead core.
