Title: Device for supporting the mandrel rods of expanding rolling mills
IPC: B21B25/02
Filed: 1932-01-22
Abstract: 376,193. Rolling mill mandrels. MANNESMANNRÍHREN-WERKE, 1B, Berger Ufer, D³sseldorf, Germany. Jan. 22, 1932, No. 2072. Convention date, Feb. 10, 1931. [Class 83 (iv).] In a rolling-mill the mandrel rod, which may be subjected to compression or tension, is provided with external means giving effective permanent support for the rod along the whole of its length during the whole rolling operation. The rod 1, Fig. 1, is disposed within a tube 3 whose diameter is less than that of the work, and is supported along its length by rings carried interiorlv of the tube. In a modification the sag of the tube due to its weight is counteracted by mounting the end of the tube 3, Fig. 3, in a bearing in the thrust-block 4, which is tilted in the direction of the arrows. Instead of the tube one or more bearers may be employed as the supporting member. When the mandrel rod is to be rotated the tube 3 may be rotated also, or it may be stationary in which case the supports are constructed as bearings. The tube may be used as a conduit for a cooling medium for the rod.

Title: Packages and containers and methods of packaging
Inventor: FIENUP WILBUR GEORGE
IPC: B65D3/26
Filed: 1955-01-24
Abstract: 807,753. Containers : packages. R.- C. CAN CO. Jan. 24, 1955, No. 2116/55. Classes 66 and 94(1). A package designed to permit easy and substantially full length opening thereof comprises an inner wrapping having a weakened separation line extending substantially the full length and an outer reinforcing wrapping superposed around the inner wrapping and having at least the portion overlying the separation line removable to expose said line. The inner wrapper 12, Fig. 5, is lined with metal foil 21 and has abutting edges 16, 17, constituting a helically formed separation line pitched to extend around substantially the entire circumference of the body wall. Adjacent to the abutting edge 17, the inner wrapper has a printed coloured line 18. The outer wrapping 13 has a first glue strip 25 along one edge 23, to secure said edge to the inner wrapper 12, and a second glue strip 26 adapted to cover the separation line 16, 17, but not the printed line 18. To the outer face of the wrapper 13 is glued a label 14, Figs. 5 and 6, offset such that the glue 31 thereon overlaps the abutting edges 23, 24, of the outer wrapper 13. A paper strip 34, on the glue 31 beneath the label 14, overlaps the edge 24 of the outer wrapper 13 to prevent the edges 23 and 24 from being joined together by the glue 31. The label 14 has a free unattached flap portion 32 constituting a peeling edge 30. To facilitate the removal of the overlapping part of the label 14 from the outer wrapper 13, and the removal of the glued parts of the outer wrapper 13 from the inner wrapper 12, the wrappers 12 and 13 are preferably of chip paper material, or equivalent fibrous material, faced with newsline facing that is easily peeled from the fibrous under material. The package has metal end caps 19, 20, and at one end has a circumferential cut 37 in the label 14 and outer wrapper 13 to facilitate opening, the cut being sealed by one or more coats of paraffin. The container is particularly applicable to the packaging of dough biscuits 10. The dough generates a gas pressure which, when the outer wrapper 13 has been removed to expose the abutting edges 16, 17, of the inner wrapping 12, should burst the foil liner and the helical seam of the inner wrapper as in Fig. 8. If the gas pressure is insufficient the container may be rapped against a table edge 42, as in Fig. 7, adjacent the line 18. Alternatively, after the outer wrapper has been removed, the ends of the package may be grasped and twisted in opposite directions.

Abstract: 607,049. Cycle bells. WEBMORE (BIRMINGHAM) & CO., Ltd., and HARRIS, I. R. Jan. 24, 1946, No. 2320. [Class 13] The striking mechanism of a cycle-bell consists of a hammer-lever 4 and a triggerlever 2 connected by a stressed helical tensile spring 5 to provide a toggle action so that when the trigger-lever 2 passes through the deadcentre the hammer-lever 4 is impelled to an alternative position with a velocity sufficient to overshoot a rest position in which the spring 5 rests against one of the stops 9, Fig. 1, and strike the dome 7. The trigger-lever 2 is biassed to one particular position by a spring 8, Fig. 1, so that pressing and releasing the triggerlever 2 produces a double action strike as the hammer takes up first one position and then returns to the other.

Filed: 1928-01-28
Abstract: 284,352,. I. G. Farbenindustrie Akt.- Ges. Jan. 28, 1927, [Convention date]. Electrodes.-An accumulator plate consisting of a lead grid the openings in which are filled with an alloy of lead and sodium or other metal is made by first casting prisms of the alloy in the spaces of a deep grating c in a mould a. The grating is then removed and molten lead poured into the mould between the prisms. The whole block when cooled is sawn into plates of the required thickness and the metal with which the lead is alloyed is removed and the plate formed in the usual way. In a modification of the process the lead framework is first made by casting lead round prisms of suitable material located in the mould. These prisms are then removed and the alloy cast into the spaces so formed. In order to keep the lead framework cool during this process, prisms of iron may be inserted in the spaces surrounding the space which is being filled with the molten alloy. In a modification the block of lead alloy and the plates obtained therefrom have only an external lead frame. Specifications 23198/94 and 270,763 are referred to.

Abstract: 401,254. Wireless receiving-apparatus. GAVORET ET CIE, G., 21, Rue Dautencourt, Paris. Feb. 2, 1932, No. 3101. Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 28, 1932]. [Class 40 (v).] A multiple variable condenser comprises two or more groups of rotor vanes on a shaft with corresponding stator groups, the profiles of the vanes of the sets being such that the meshing of their first portions will give a constant difference between the frequency of an oscillator controlled by one group of vanes and the frequency of a circuit including one or more inductances controlled by the other group or groups of vanes as one given range is covered, while another part of the profiles will give the same constant difference between the frequency of a second oscillator and that of a second circuit or circuits as a given frequency band is covered. Thus during the rotation of the rotor, a group 22 will move from the position shown in full lines in the Figure, in the direction of the arrow f<1>, to the position in which the point 3 is in the position 5, and one set of vanes will tune the shortwave inductances over a given range, while another set will tune the oscillator to a frequency differing from that of the tuned inductances by the adopted intermediate frequency. The movement from position 5 to position 8 is not used for tuning and is used for switching over inductances and oscillator to long waves or in one position to switch off the receiver. The movement from position 8 to position 9 is utilized so that the decreasing capacities tune the two, or more, circuits to respective frequencies differing by the same amount over a long-wave band and the movement from 9 to 3 again is utilized to switch back the appropriate short-wave circuits. The shapes of the vanes are determined by selecting an appropriate law for one set and determining the outline of those of the other by calculation or experiment.
