Title: Improvements in and relating to the manufacture of containers and closures therefor
IPC: B21D51/26
Filed: 1930-06-04
Abstract: 355,397. Tins and closures therefor. BRITISH SURE SEAL CO., Ltd. and HUXLEY, J. J., 132, Lots Road, Chelsea, London. June 4, 1930, No. 17292. [Classes 66 and 125 (iii).] In a tin container having a groove near the mouth for the reception of the lower flange of a jointed locking ring, the body is formed with a lap joint over the area of the groove. The remainder of the joint may be wholly or in part a lock joint, or all the joints may be lapped and soldered. In forming the tin, portions such as 19, 20, Fig. 12, are cut away from the blank, the' edges are folded over in the same angular direction about the lines 19a, 20a, and the folded edges engaged to form a lock joint except for the shaded portion 21, Fig. 13, where the edges are merely lapped, the resulting tin having a lap joint from groove 2, Fig. 3, to the mouth flange 3. Alternatively a rectangular portion may be cut from one edge where the groove is to be formed and the corresponding portion of the opposite edge be left unfolded. The mouth of the tin is either curled or flanged inwards to form a smooth surface against which a packing ring can engage or the edge comprises an inturned slightly upstanding flange 3, Fig. 3, adapted to be bent down by the packing whose application it resists. The rubber latex or other packing is disposed in an annular recess 12a, Fig. 10, having a sloping inner edge to provide engagement between the packing ring and the side of the curled edge of the tin as well as the top thereof. The part between the groove and the mouth may be tapered to produce a " glass " finish or may be formed with inclined threads or ribs for the reception of a bayonet joint or other interlocking cap. The closure cap may be a frictiontight cap, a snap-on cap having short inturned flanges in opposite halves and shallow flanges connecting them, or a cap having a rolled flange 11, Fig. 8, which is flattened prior to ribs 4a being pressed inwards from it. The cap may comprise a disc retained by a ring and, if a friction cap is employed with a vacuum container E, the flange thereof may be cut away at one portion to permit of the insertion of a knife &c. to break the vacuum. The locking ring used may be that described in Specification 336,302, [Class 125 (iii), Stoppers &c.], and comprising a tongue 15, Fig. 11, in the tail thereof adapted to engage the base of the tongue 16 in the head thereof, a bead or groove 14 being formed adjacent the lower edge of the ring to facilitate its application to the tin. In forming the groove in the tin a shoulder 31, Fig. 16, on a laterally displaceable rotary former 29 flanges the end of the tubular blank C which is disposed on a rotary block 28 and then a member 33 on the former co-operates with a groove 32 on the block to form the groove, the blank engaging a shoulder 30 on, and being supported throughout almost its entire length by, the block 28. The groove may be shaped to accommodate a spiral applying ring by which the ring is secured to the tin.

Patent GB-758652-A (GB)
Title: Method of producing a penicillin-containing fodder
Inventor: JESPERSEN ERIK
IPC: A23K20/195
Filed: 1953-06-23
Abstract: Penicillin particles for distribution in animal feed are coated with or embedded in a fusible substance which protects the penicillin against the decomposing influence of moisture, oxygen and penicillinase but which is melted or dissolved by the digestive juices of the animal consuming the feed, the penicillin compound being mixed with the substance in a molten condition and the mixture being sprayed into a stream of air at a temperature lower than the melting point of the substance so as to produce solidified droplets. The protective substance is exemplified by tallow, lard, hydrogenated vegetable or fish oils of low iodine number, polyethylene glycols of m. pt. above 40 DEG  C., partial esters of hexitol anhydrides, e.g. sorbitan monostearate and monopalmitate, and solid polyoxyethylene oxide derivatives thereof, low mol. wt. amine- or amide-aldehyde, e.g. urea-formaldehyde, polymerizates, esters of polyhydric alcohols with natural resins, and natural or synthetic waxes.  The penicillin compound is preferably sparingly soluble in water, e.g. is the penicillin derivative of the diethylaminoethyl ester of p-aminobenzoic acid (procaine penicillin) or of p-hydroxybenzoic acid, or is the penicillin derivative of N,N1-dibenzylethylenediamine.  Before the solidified droplets are incorporated in the feed, they may be mixed with a substance which adheres to the droplets and does not decompose penicillin, such substance being exemplified by dried lucerne meal or calcium carbonate, which may have been impregnated preliminarily with a solution of a bactericide, e.g. sodium-(ethyl mercuri)-thiosalicylate, sodium benzoate or ethyl p-hydroxybenzoate. An example is concerned with preparing a feed containing 20 i.u. of penicillin/g., and showing no loss of penicillin after 6 months, by spraying a suspension of 1 part of procaine penicillin in 3 parts of molten hydrogenated soya oil downwards into a horizontal stream of air at a temperature of 20 DEG  C., collecting the droplets on a travelling belt, mixing 1 part of the droplets with one part of fodder, and then incorporating this mixture into 125 parts of the fodder.

Title: Straightening rotating circular-section workpieces
IPC: B21D3/04
Filed: 1971-05-27
Abstract: 1344702 Straightening rods TH KIESERLING & ALBRECHT 27 May 1971 [17 Oct 1970] 17584/71 Heading B3M [Also in Division B8] Circular-section workpieces 68 to be straightened between rollers 9, 10 are fed by rollers 5, 6 whose rotational axes 5a, 6a are adjustable, Fig. 4, to vary the speed at which the workpieces are conveyed. The gap between the ends of workpieces which normally arises during transfer of workpieces from a feed grate 2 to the straightening rollers 9, 10 may thus be eliminated by accelerating the trailing workpiece 68a. Each roller 5, 6 driven by an hydraulic motor 34, is mounted on a pivot 25 extending at right angles to the longitudinal axes of the workpieces, Fig. 2. A piston-cylinder assembly (29), Fig. 3 (not shown), causes rotation of the pivot 25 between adjustable stops (32, 32a). For pivoting the roller-pivot assembly 5, 25 about an axis parallel to the axes of the workpieces, a bracket 19 which supports a housing 24 for the pivot 25 is rotatable by pistoncylinder assembly 21. The pivots 25 are longitudinally adjustable by handwheels 27. Both roller-pivot assemblies are vertically adjustable by screws 18, 23. In operation a workpiece 68a from a grate 2 is fed into a trough 1 and between the rollers 5, 6 by reciprocating means (94-96) Fig. 6 (not shown). The roller assembly 5 is then tilted to its "closed" position, Fig. 2, by the cylinder 21 and a second workpiece is prepared for dropping into the trough 1. With the workpiece 68a in the position shown in Fig. 1, the pivots 25 are positioned to provide a high rate of longitudinal speed with a low rotational speed and the gap between the workpieces 68, 68a is closed. The leading workpiece 68, having undergone straightening, passes via a trough 12 into delivery apparatus 13, a discharge trough 14 and a discharge grate 15. When the gap between the workpieces has been closed the rollers 5, 6 are returned to their positions for normal feed of the workpieces. The sequence and timing of the operations is controlled by sensor coils 8, 11 and by time relays. Fig. 5 (not shown) illustrates an hydraulic system for the apparatus. In a modification, Fig. 7, the rate of feed of the workpieces towards the straightening rollers is altered by varying the speed of the feed roller motors 34, 34a; the feed rollers 5, 6 are not pivotally mounted.
