Title: An improved method of and apparatus for packing or canning food and other plastic substances
IPC: B65B39/00
Filed: 1943-03-25
Abstract: 567,045. Packing food and other plastic substances. YUILL, W. M. March 25, 1943, No. 4831. [Classes 94 (i) and 125 (ii)] [Also in Group V] Packs of casingless sausages of a plastic substance are produced by passing a receptacle forward over a freely-supported extrusion die 16, Fig. 1, having a number of open-ended elongated passages therein until the base of the receptacle 32 engages the end face of the die, extruding the plastic substance through the die to press the receptacle away therefrom until the desired amount has been extruded, releasing the extruding pressure, and cutting the substance at the end face of the die to leave the pack of sausages within the receptacle. The filler casing 15 and die 16 are screwed together and the material forced therein through an inlet 26. The disc cutter which works over the end face of the die to sever the extruded sausages may be mounted on a central spindle or may be in the form of a sleeve. In order to produce sausages of a predetermined size, the filling apparatus is mounted by the flange 27 on a shelf 28 through which project stop members 30, 31 mounted on a rod 34, Fig. 6. The stop 31 is connected by a crank 35 to a lever 36 fixed to a spindle 37 which also carries a lever 47 connected at 47a to means for starting and stopping the press. When a can 32 is mounted on the die 16, the rim 33 engages the stop 31 and moves it back on the rod 34, thus turning the spindle 37 and raising the end 47a of the lever 47 to start the press. The substance is extruded through the die 16 into the can 32 which recedes and moves the stop 30 until in a predetermined position the eye 39 strikes the collar 42 on the rod 40, thus rocking the spindle 37 to stop the press. The cutter is then rotated to sever the sausages and the can removed, this action causing a pin 48 on the sleeve 30a to engage a catch 49 pivoted at 50 on a block 51 under control of a spring 53. In putting a fresh can over the die 16, the stop 31 turns the spindle 37 clockwise, thus pulling the rod 40 to the right and releasing the pin 48 from the catch 49 and permitting the weight 46 to move the stop 30 into engagement with the base of the can 32. In a modification, the casing 15a, Fig. 9, has an inlet connection 26a, while the disc cutter 22a is carried on a sleeve 56 movable within the limits of the slot 57. The stops 30, 31 may be omitted from the apparatus shown in Fig. 1, or may be provided in association with that shown in Fig. 9. The sausages may be delivered into a folded paper wrapper which may be supported on the die 16 by a can. If desired, the length delivered may be greater than the length of the can or wrapper, Specification 543,452 is referred to.

Abstract: 832,446. Cartons; packages. BRITISHAMERICAN TOBACCO CO. Ltd. Feb. 14, 1958 [Feb. 25, 1957; Jan. 7, 1958], No. 4854/58. Classes 18 and 94(1). A carton for cigarettes &c. is provided with a slidably mounted closure flap 34 adapted to open and close an aperture 13 in the top wall of the carton, the flap 34 being hinged at 35 to a flap 30 forming the upper part of the end wall 21. A thumb operated tab 32 is provided on the flap 30. Flaps 12 and 26 form upper and lower guides respectively for the closure flap 34. The side wall 11 is folded finally and the carton is held together by means of adhesive G on the bottom wall flaps 15 and 16. In a modification there is no lower guide flap 26, the cigarettes and their paper wrapper serving this purpose. Interior ribs to act as guide means for the closure flap may be formed at the top of the side walls by suitable fold lines.
Patent GB-721293-A (GB)
Title: Improvements in or relating to a tape-dispensing machine
Inventor: KRUEGER ALFRED PAUL
IPC: B65H35/00
Filed: 1952-02-25
Abstract: 721,293. Adhesive tape dispensers. DERBY SEALERS, Inc. Feb. 25, 1952, No. 4871/52. Class 18. A dispenser of self adhesive tape comprises a number of feed discs 19 having irregular peripheral edges for engaging the adhesive side of the tape and a number of stripping discs 22 also having irregular edges adapted to be spaced intermediate the feed discs and to overlap them so that as the discs are rotated the stripping discs disengage the tape from the feed discs and enable it to be delivered or withdrawn from the dispenser. The feed discs are driven by an electric motor controlled by a switch 41 which is actuated by a cover element 65 or by the support for a severing member 71. For this purpose one of the arms 74 supporting the severing member 71 is provided with an extension which is slotted as at 76 and loosely engages a pin 77 on the cover element 65 and is also provided with an arm 79 adapted to actuate the switch 41. The arm 74 is pivoted to a normally stationary lower cover plate 29 so that in the event of either the cover element 65 being raised by the tape being grasped and pulled against its lower edge 69 or by depressing the severing member 71, the switch 41 is actuated to effect operation of the motor and a feeding of the tape. Feeding is stopped when the tape on the serving member is released. The stripping discs 22 are mounted on a shaft geared to the shaft carrying the feed discs the gear ratio being such that the peripheral speed of the stripping discs is greater than that of the feed discs thereby lessening the tendency for the tape to adhere to the stripping discs. In the event of the tape so adhering to the stripping discs a comb 85 is provided adapted to engage between the discs 22 and remove the tape. The switch 41 is pivoted and may be swung to either an operative or inoperative position. The cover plate 29 to which is also attached the cover element 65 can be swung to an open position, Fig. 5, and in so doing causes the switch 41 to move to its inoperative position. The switch may then if desired be moved back to its operative position but is again moved to its inoperative position upon closure of the cover plate 29. The severing member 71, which may be adjustable angularly, has a stripper 73 for disengaging the tape from the cutter in the event of it adhering thereto after it has been severed. The action of severing the tape also serves to prevent feeding by pivoting the arms 74 in the reverse direction to the switch actuating direction.

Title: Improvements in or relating to process of obtaining crystalline salts of penicillin
IPC: C07D499/16
Filed: 1948-02-23
Abstract: Crystals of ammonium, sodium or potassium penicillin salts are prepared from an aqueous solution of such salt obtained directly from a penicillin broth by solvent extraction procedure comprising alternate extraction of the penicillin from aqueous solution into an organic solvent under acid conditions and back into aqueous solution under alkaline conditions, by transforming such solution into a reduced volume solution of the salt in a solvent of which at least 95 per cent is an organic solvent selected from monohydric alkanols of not more than 6 carbon atoms per molecule, cyclohexanol, benzyl alcohol, saturated acyclic monoketones of not more than 6 carbon atoms per molecule, cyclohexanone or mixtures thereof, the transformation being effected by both evaporation (preferably under reduced pressure) at a temperature below that at which material penicillin destruction occurs and addition of the organic solvent, and being carried to a point at which the volume of solvent is less than sufficient to hold in solution all the penicillin salt present. The evaporation (which may in some cases be taken to dryness with subsequent putting back of a certain amount of water) and the addition of the organic solvent may take place in either order, or may be effected in stages which are alternated.  Advantageously the starting solution is obtained by extracting a penicillin broth under acidic conditions (pH 2-3) with 10-20 per cent of its volume of amyl or butyl acetate, and extracting the acetate solution with 1-10 per cent of its volume of an aqueous solution of ammonium, sodium or potassium hydroxide, carbonate or bicarbonate.  It is also desirable (but not essential) to treat the acetate solution, or the solution obtained by addition of the organic solvent to the aqueous solution, with a small quantity (e.g. 1/2 -2 per cent) of activated decolorizing carbon.  Examples describe the use of n-butanol and acetone as solvents.  Amyl (especially isoamyl), n- and isopropyl, methyl, ethyl and hexyl alcohols, and methyl ethyl, methyl n- or iso-propyl, methyl n-, iso-, sec.- or tert.-butyl, diethyl and ethyl n- or isopropyl ketones are also specified. Specifications 600,719, 642,370 and 642,371 are referred to.
