Filed: 1923-06-04
Abstract: 220,741. Scanes, A. E. L., and Metropolitan-Vickers Electrical Co., Ltd. June 4, 1923. Inductances.-In a variometer transformer of the kind in which one or each winding is divided into relatively-rotatable coaxial coils for varying its inductance, a part or the whole of one winding is made angularly adjustable with respect to a predetermined part of the other winding for the purpose of varying the coupling between the windings. In one arrangement, Fig. 1, each winding comprises a pair of coaxial coils, the larger coil 1 of the primary winding being wound on a bobbin 6 carried by a lever 7 pivoted at 8 so that the coupling between the coil 1 and the larger coil 3 of the secondary winding can be adjusted. The smaller coils 2, 4 of the windings are wound on a bobbin 9 which can be rotated for the purpose of simultaneously varying the inductance of the two windings. In a modification, the surfaces of the bobbins are made portions of spheres for the purpose of giving a tighter maximum coupling. In another construction, Fig. 3, one winding only is divided into coaxial coils 12 - - 15 on relatively movable bobbins 16, 17, the remaining winding comprising a single coil 19 on an angularly adjustable bobbin 20. Specification 205,948 is referred to.

Abstract: 658,056. Mincing-machines. SIVERTSEN, P. M. June 1, 1949, No. 14718. [Class 28(ii)] A meat-mincing machine is provided with a rotary cutter 47 spaced rearwardly of a mixing member or of cutting blades 66 adjacent to a perforated front plate 8. As shown in Fig. 3, this rotary cutter may comprise three graduated discs 48, 49 and 35 spaced apart by webs 50 and 51. Alternatively the cutter 47 comprises separate or combined discs with no spacing webs, or a single disc, or a spiral cutting cone 77 combined with a disc member 79 as shown in Fig. 8. In a mixing chamber between the rotary cutter 47 and the front plate 8 there may be one or more removable pins 55 causing the meat to be mixed as it passes through the mincer. The mincer body has an internal and removable sleeve 20 provided with a plurality of axially extending ribs 21. In all cases, the rotary cutters described above coact with cutting edges formed by the ribs 21, to shear the meat. Whereas the usual worm 19 may be supported at the cutting end of the mincer by an axial extension 15 passing through a central aperture 14 in the front plate 8 it is possible, according to one modification described, to support the worm 19 at this end by suitably shaping one of the disc cutters to bear in a smooth portion of the sleeve 20.

The corners of the sheet 25 are cut diagonally at 12, and the sheet is folded along the transverse central line 1 with the roating 15 inside of the folded blank. Heat or pressure is then applied to the marginal portions 2 to form seams. The side portions of the container are then folded inwardly along lines 9, 10 as well as along the lines 4, 5, 6, 7 to form a longitudinally extending re-entrant or gusset fold at each side of the container. Ear portions A, Fig. 6, are also formed as a result of the folding operation. The container is now placed in a receptacle 20, Fig. 6, of wood &c. of slightly larger size than the container when opened out. The ears A are folded over as shown in Fig. 6. The foodstuff such as molten cheese is poured into the container, and forces the container walls to take the shape of the receptacle 20. After the container has been filled to the level of the top edge of the container, the upper marginal portions 16 of the container are brought face to face and sealed, and then folded upon the body of the packet to form a hermetic seal.
