Abstract: 794,241. Guiding vehicles and trailers. DAIMLER-BENZ AKT.-GES. July 2, 1956 [July 4, 1955], No. 20444/56. Class 79(5) [Also in Group XXXII] In a motor vehicle or trailer, a trailing axle 5 is axially slidable in bearings 12, 12, secured to leaf springs 13, 13, the latter being displaceable longitudinally but not transversely of the vehicle. Struts 6 rigid with the axle 5 are resiliently mounted forwardly at 8 by means of a rubber bushing 9 which permits a degree of lateral movement as shown in Fig. 2. The bearings 12 are connected to the respective leaf springs 13, 13, by resilient sleeves 11. A disc 17 rigid with the axle 5 is adapted to be engaged by centering springs 18, 18, the other ends of which are rigid respectively with rods 14, 14, secured to the springs 13, 13. Extensions of the rods 14 are connected by a tie bar 15. The springs 18, 18, are under a predetermined degree of precompression. In operation, when the vehicle is negotiating a bend the axle 5 is able to move laterally in the bearings 12 and the resilient sleeves 11, 11, and the bushing 9 permits a degree of obliquity of the axle 5 in relation to the vehicle frame. The springs 18, 18, provide a centering action. Both ends of the springs 13 are mounted by straps which permit the longitudinal movement.

Abstract: 248,258. Traitteur, F. O. von, and Schnellpressenfabrik Frankenthal Albert et Cie., Akt.-Ges. Aug. 17, 1925. Stereotype, casting.-In stereotype-plate casting-apparatus in which the metal is supplied to the mould from a hopper to which it is supplied from the melting-pot, the hopper is provided with one or more ducts, separate from the supply duct, by which surplus metal can return to the pot, thereby enabling the metal in the hopper to be kept in circulation either continuously or during the cast. The hopper d receives metal from the pot b by a supply pipe c and surplus metal returns to the pot through overflow channels f<1> in the upper wall f of the hopper and through one or more ducts g which may be valvecontrolled. The ducts g and wall h of the hopper may be kept heated by a device e. One or more devices l of inverted V-shape may be arranged beneath the supply pipe c to render the flow of metal into the mould e more uniform throughout its length. A slide n operated by hand or mechanically is provided to close the outlet from the hopper. The apparatus may be used for casting curved or flat plates and a number of moulds may be connected to one metal pot.

Title: Process and apparatus for the manufacture of tubes from sheet metal
IPC: B21C37/08
Filed: 1932-07-21
Abstract: 396,549. Making tubes. ROCCHI, V., 25, Via S. Gregorio, Milan, Italy. July 21, 1932, No. 20646. [Classes 83 (ii), 83 (iii), and 83 (iv).] Bending; milling; broaching; cold-rolling; shearing; welding.-Tubes are formed by passing sheets while cold through a continuous machine wherein they are sheared to width, shaped at the edges, bent up to cylindrical form, electrically welded and finally rolled and sized. A sheet is fed from the pile through rolls 3, 4, Fig. 3, and is sheared to width between discs 5, 6, backing-up rings 9 of metal being supported on discs 10 of hardened gum or other resilient material. The sheet is then conveyed by rolls to further conveyer rolls 14, at the side of which are supported circular cutters 15 having teeth about their periphery and stationary knives 16, Fig. 22, comprising a series of cutting edges which complete the shaping of the edges of the sheet to the form of Fig. 7. A series of pairs of rolls 17, 18, Fig. 1, then bend the sheet successively until it assumes a substantially circular form, the gradually-formed tube being guided by vertical rolls during this operation. Co-operating rolls 22, 23 and an internal mandrel 24 then shape the open-sided tube to circular form. After passing over a guiding roll having a flange which enters the longitudinal gap in the tube, the tube is closed between rollers 28 and welded. The pressure of the electrodes 29, 30 may be adjusted from a handwheel through a screwed rod and from a lever 38 through a bar 37 respectively. Water is circulated through the electrodes for cooling. The welded tube passes between a series of rollers and over a co-operating mandrel to size it accurately, and strikes a stop at the end of the operation to close an electric circuit whereby the rolls are reversed to return the tube. In a modified form of sizing apparatus, the tube 50, Fig. 21, passes into a hinged tube 61 in which there rotates a mandrel carrying skew rollers 57<1>, the tube 61 being moved longitudinally.

Each tip 30 is carried by a holder 22 which is urged into its upper position by a spring 24. The dispensing device comprises a cylinder 44 in which slides a piston 42 which is also urged into its upper position. Each  tip 30 is forced downwards by the piston 42 on pressurizing the space in the cylinder 44 above the piston 42. When the piston 42 reaches its lower position; a duct 72 therethrough communicates with a source of inert gas at high pressure, which forces the sample from the tip 30 into the cell 12. The gas above the piston 42 is then exhausted and the piston 42 and the holder 22 move upwards under the action of springs 64, 24. In a modification the piston 42 is driven by a motor.
