Title: A hydraulic press for moulding and vulcanizing pneumatic tyres
IPC: B29D30/06
Filed: 1919-04-11
Abstract: 142,634. Lefebvre, E. April 11, 1919. Vulcanizing tyres.-In an hydraulic press for shaping and vulcanizing cycle tyres, the up and down movement of the platen effect the whole of the operations automatically. The internal shaping-mandrel consists of 6 parts a, b, Fig. 5, mounted on T-shaped slides which run in radial grooves in a plate o, the slides of the parts a being toothed and engaging the spiral groove of a rotatable disk P, which is keyed on a hollow shaft L splined within a pinion R in gear with a pinion S driven through bevel pinions T by a rack pinion V. The plate o is fixed to a plate M provided with lugs N engaging grooves on the chamber H to prevent rotation. The outer former comprises a fixed head or yoke D having a heating-chamber I and a movable platen G with heating-chamber H. The platen G is raised by the hydraulic plunger A, and the pinion V, traversing a rack Y mounted on one of the sleeves X, rotates the disk P to close the shaping-mandrel. When closed, adjustable stops m reach hooks j, catches f fixed to the columns are released and the upward movement of the sleeve X commences, so that the pinion V moves up with the rack, and the tyre is pressed between the upper head D and the lower platen G on the one hand and the internal mandrel on the other. In this position, the press is locked by the heels of the catches f projecting into the sleeves, and the press is left during the period of vulcanization. When this is effected. the water is run out of the hydraulic cylinder, and the movable members fall bv gravity and by the action of a hydraulic cylinder in the head D pressing upon the mandrel. When the sleeve X reaches a stop Z on its column, the pinion V begins to rotate, and contracts the mandrel so that the vulcanized tyre can be removed and another tyre substituted. The catch f falls into its horizontal position and is secured by the stops m engaging the heels of hooks j.

Filed: 1954-04-01
Abstract: 804,333. Rotary meters. DEBOW, H. R. A., and KING, R. F. J. April 1, 1955 [April 1, 1954], No. 9599/54. Class 110 (2). [Also in Group XXXVIII] Apparatus for measure quantity or velocity of fluid flow comprises a propeller rotating in the fluid flow and arranged to produce an output pulse each time part of the blade passes a reference point. The propeller is homogeneous with its boss and is made from an unplasticized polymethyl resin formed with an integral hollow spindle into which stainless steel pivots are inserted at the ends. The propeller is suspended for free rotation in jewelled bearings 5 supported at the axis of a polymethyl methacrylate tube 2, by radial fin 6. The tube 2 is supported in a flanged length of pipe by rubber rings 3, but holes are provided so that the flow is not excluded from the space between the rings. A fine conductive probe 8 of material resistant to corrosion by the liquid, e.g. gold, projects to the central tube as does a further probe 11. A third probe 12 enters the liquid surrounding the polymethyl methacrylate tube only. The propeller is so situated that the conductivity of the path between probes 8 and 12 varies each time a blade of the propeller approaches while that between 8 and 11 does not. The probes with intervening liquid, form two arms of a bridge circuit fed with a 10 kc/s. signal and balanced when no blade is near the probes. Thus the bridge output is a 10 kc/s. carrier modulated at a frequency dependent on the speed of rotation of the propeller.
