Abstract: 762,911. Buckles. WALKER, Ltd., T. April 15, 1955 [Aug. 13, 1954], No. 23504/54. Class 43. A buckle of the cast off type comprises a main buckle frame 1 provided at its inner end with a hinged or rigidly attached extension plate 4, the rear end 7 of which is bent or cranked rearwardly at an angle and then curled around one bar or part of a loop member 8 constituting a lay band or keeper loop for the free end of a belt secured by the main buckle, the bent or cranked portion of the extension plate having an aperture 13 for receiving a hook 18 on the end of a member 14 secured to the non-adjustable end of the belt. The hook member may comprise a sheet metal plate with side ears 16 between which a lever-grip device 17 is pivoted and by means of which the hook is removably secured to the end of the belt.

Abstract: 626,436. Making section wires. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 27, 1947, No. 23723. Convention date, Aug. 27, 1946. [Classes 83 (ii) and 83 (iv)] Welding ; shearing.-In making sectional wires of two welded sections of different composition for radio tubes, discharge tubes, electric lamps, &c., three wire lengths are welded together end-to-end and the intermediate section is cut to divide the wire into two two-section wires. A two-section wire with one section of very short length may also be made by forming a welded two-section wire having one section longer than desired so that it can be effectively held in the welding apparatus and then cutting off one of the sections to the required length. One section may be of nickel and the other section of copper-clad steel to seal into glass. In making the three-section wire the end sections may also be of different size or composition from each other. The three lengths may be welded together as described in Specification 446,409, and the subsequent cutting effected in the centre of the intermediate section or at some other point thereof. The end lengths 1, 2 of nickel may be mounted in the grooves of drums 5, 51 and secured in the jaws 4 of the welding apparatus and the copper-clad steel wire 3 in the jaws 6, 7, and the wires 1 and 2 successively welded to the wire 3 by movement of the jaws 4. The welded wire is then released from the jaws and fed by the drums to the shearing mechanism 23, 25. The drums are rotated through Geneva mechanism from shafts 12 connected by bevel gear 14, 15 to the shafts .13. The ends of the welded wire, during transfer to the shearing mechanism, engage respectively a spring finger 16 and a stop 19 to position them in the required position. In a modification the stop 19 may be replaced by a solenoid energized through actuation of a switch by the main drive. The wire passes between a stationary clamping block 23 and a slidable cutter 25 reciprocated against the action of a spring by levers 33, 37, link 38 and lever 40, by a cam 42 on the shaft 12. The cutter is connected by a pin 31 and slot to a clamping block 30 which is pressed forward by a spring 32 so as to hold the work during the cutting operation. The cut wires are carried against and move down the plates 45. The bracket 24 carrying the block 23 and the bracket 26 carrying the cutter 25 may be adjusted to vary the cutting position.

Patent GB-1551402-A (GB)
Title: Method of removing distortion from a metal plate
IPC: B21D1/12
Filed: 1976-06-09
Abstract: An indented deformation on a metal plate which is accessible from only one side, e.g. on certain double-walled car parts, is removed in the following manner. First of all, a bolt (2) is fastened on the indented region (A), e.g. by adhesive bonding or welding. The bolt (2) is connected to a tension tool (3), and a mass (7) which is fitted on the tension tool and effects a striking action away from the bolt changes the indent into a protuberance. By hammering, the protuberance is then levelled out. Hammering can be carried out by means of an electric hammer which, on each strike, heats the working point by induction. <IMAGE>

Patent GB-778199-A (GB)
Title: Preparation of an antigen for the treatment of tuberculosis
IPC: C07K16/12
Filed: 1953-09-02
Abstract: An antigen useful in the treatment of tuberculosis is prepared by subjecting an aqueous suspension of a dead Koch bacillus (Mycobacterium tuberculosis) and its products of metabolism to a precipitation reaction with an equivalent amount of an antibody solution, which is immune plasma, serum or blood (diluted or not with water) derived from an animal immunized with the dead Koch bacillus by inoculation with the latter in a dead or attenuated state and separating the upper liquid phase.  An antitubercular serum may be prepared by injecting the said upper liquid phase into an animal e.g. ox, sheep, pig or rabbit, and in due course extracting blood therefrom aseptically and preparing it for use as a serum.  In the example, 1 c.c. tuberculosous bacterial antigens are mixed with 1 c.c. old tuberculin diluted with water and allowed to stand three hours (Reagent 1).  This is injected into a bullock in small doses over 26 days, three months from the first injection allowed to lapse, and then blood is withdrawn aseptically.  After standing, the serum is separated, cresol is added, and after standing three weeks the serum is filtered through cotton, earth and porcelain filters (Reagent 2).  Six or seven drops of this serum are added to 1 c.c. of Reagent 1 and the mixture allowed to stand 24 hours at 37 DEG C.  The clear liquid is withdrawn, treated with another drop of serum (Reagent 2) and incubated 24 hours at 37 DEG C.  This is repeated until the addition of a drop of serum fails to produce a reaction after incubation. The so produced mixture is incubated at 37 DEG C. for a further 48 hours, and then at 55 DEG C. for 20 minutes.  The liquid produced when decanted from any residue is injected into an animal, which may be the same or different from that previously employed, and the antitubercular serum finally obtained from the blood of the animal is used medicinally for the treatment of tuberculosis in humans and animals.  The antigen prepared by the above process from M. Tuberculosis var. hominis is used to treat humans and that from M. tuberculosis var. bovine to treat animals.
