Title: Rotating shear for cropping high-speed rolled stock
IPC: B23D25/12
Filed: 1968-01-09
Abstract: 1,219,191. Shearing. SCHLOEMANN A.G. 9 Jan., 1968 [25 Jan., 1967], No. 1222/68. Heading B3W.  Rotary shear for cropping rolled stock, e.g. wire, moving at high speed comprises two rings 14 mounted side by side on respective driving shafts 3, 4 revolving at the same speed and having circular cutting edges facing one another and converging at an acute angle until the edges are at the distance required for shearing the wire. Preceding the shear is a switching member 15 rockable by e.g. piston and cylinder means 18 between one end position, Fig. 2, in which it directs the end of the wire (not shown) into the free space between the cutting rings 14, and the other end position, when it is directed tangentially to the periphery of the rings. As the switching member is rocked upwardly it lifts the wire into engagement with the cutting edges and the wire is completely sheared at top dead centre position (20), Fig. 3 (not shown). The crop end is guided by a plate 21 to a scrap container and the new wire end is impelled on the periphery of one of the rings into an outlet guide 22. In a shear for single-line operation, Fig. 4 (not shown), the housings 1, 2 carrying the cutting rings are displaceable relative to each other on base plates (23) rockable about a common pivot (24) and each supported on hinge-rods (25), (26). A piston (29) of adjustable length acts on the pivot point (28) between the rods (25), (26). To vary the acute angle between the cutting rings without varying the distance between the cutting edges at the narrowest point of the cutting range the piston rods are shortened, the housings are displaced on the base-plates and fixed by screws (32). For cropping the front and rear end of wire to be wound on a reel two shears are provided in series, the front shear preferably having upwardly converging cutting rings and the rear shear downwardly converging rings, the cutting range of the rear shear being so far below that of the front shear that, after the front crop, the wire is guided in a straight line through the cutting rings of the rear shear.

Abstract: 657,154. Aircraft pressure cabins. SAUNDERS-ROE, Ltd., and HARDY, D. J. Jan. 19, 1949, No. 1505. [Class 4] [Also in Group X] A portlight fitted to a window opening in the wall of an aircraft pressure cabin comprises an inner domed transparent panel, subject to the pressure difference between the exterior and the interior of the cabin and held in position to seal the window opening by the excess pressure within the cabin, and an outer transparent panel flush with the outer skin of the aircraft. In the embodiment shown in Fig. 1, the thickened edge 20 of a part spherical transparent panel 19 is held by the excess internal pressure against a rubber sealing ring 17 on one side of a bezel 15. The panel 19 is in compression and its rim may slide on the ring 17 to accommodate changes in shape of the panel due to pressure and temperature changes. A rubber sealing ring 16 is mounted between the bezel 15 and a circular reinforcing member 18 surrounding an opening in the cabin skin 13. A metal ring 21 and a rubber ring 22 locate the dome in position. An unstressed transparent disc 14 is attached to the bezel 15 and has breather holes 23 passing atmospheric air to the space 24 through silica gel accommodated in an annular groove in the bezel. A third transparent panel 26 provides a duct 28 through which warm air may be circulated to prevent icing or misting and reduce heat transfer from the cabin. In a further embodiment illustrated in Fig. 7 the domed panel 19 is concave inwardly and is therefore in tension. The bezel 15 carrying the outer panel 14 is supported by an annular bracket 32 on a pressure-tight metal ring 33 mounted coaxially with the window opening and carrying a rubber sealing ring 34 against which the bead 31 at the rim of the panel 119 is held by the pressure inside the cabin. In each embodiment a conical metal fairing 27 is provided. Figs. 3-6, 8 and 9 (not shown), illustrate alternative forms of beading and sealing at the rim of the domed panel and mounting of the bezel. The construction enables windows of a given weight to be made larger and thus to function as emergency escape hatches.
