Abstract: 115,793. Kops, D. Feb. 27, 1918. Corsets.-In closedback and laced-front corsets, such as are described in Specification 113,748, arrangements are made to exert two distinct pressures on the abdomen, (1) inwardly and upwardly to produce an uplifting effect, and (2) circumferentially t o produce a flattening effect. The former is produced by means of the front lace or laces, and the latter by selfreducing straps with or without tension straps which pull in the opposite direction from the self-reducing straps. The corset body 10, Fig. 2, has front steels 11, 12 with fastenings 13, and a lacing 17 which joins two parts of the corset on one side of the steels, and which extends from the lower ends of the front steels to the top of the garment. The lacing is drawn from below upwards, whereby the first effect is produced. The second effect is produced by self-reducing straps 24, connected to the corset body along lines 29, but free at the upper, lower, and forward edges. They are provided with eyelets 31 engaging hooks 32 on the steel sections. These self-reducing straps carry hose-supporters 41. The strap on the right side may be provided with a strap 33 having eyelets engaging the hook 32. Hose-suspenders 35, 36 are provided, the latter not being connected to the body of the corset, but having an eyelet 38 which is engaged by the lace 17. In the form shown in Fig. 4, the hose-suspender straps 36 act as tension devices in the opposite direction to the self-reducing straps 24, and are continued towards the hips, where they are attached adjustably to anchorpieces 44 by lacing 46, which is fastened at the sides. A modification similar to this form has front lacing on the left side similar in all respects to that on the right. In a further modification, the front suspender straps act as self-reducing straps, the usual self-reducing straps being omitted. This arrangement is also shown in Fig. 7, but the connexion between the strap 73 and the anchor-piece is modified. The strap has eyelets 74 connected by a lacing 81 to a strap 75, which is provided with straps 77, 78 passing through metal loops 79, 80 attached to the anchor-pieces and terminating in eyelets 84, which adjustably engage a hook 85 on the front steels. In all forms of the invention, a tongue acting as a gauge covers the lacing 17 at the back, as described in Specification 114,965. Specification 115,794 also is referred to.

Filed: 1926-02-09
Abstract: 247,941. Gelsenkirchener Bergwerks- Akt.-Ges. Feb. 21, 1925, [Convention date]. Drawings to Specification. Purifying and refining; annealing. - In the production of a cast iron with the finest distribution of graphite, the molten iron is heated over (e.g. 100 to 200‹ C. over) the temperature above which the formation of carbide decreases and the formation of graphite increases, this temperature being about 300-500‹ C. higher than the temperature of solidification. In an example, a east iron containing 3.23 per cent of carbon has, after heating at 1600‹ C., 3.12 per cent of graphite and 0.11 per cent of carbide. A small amount of iron mav be so treated and then mixed with iron which is heated to its melting point or a little higher. The iron so treated is particularly suitable for casting in permanent moulds especially by the centrifugal process. The Specification as open to inspection under Sect. 91 (3) (a) states that the casting may be annealed by heating to 850-875‹ C. for a short time and then cooling slowly. This subjectmatter does not appear in the Specification as accepted.
