Title: Process for the manufacture of hollow rubber articles
IPC: B29D22/04
Filed: 1937-11-11
Abstract: 492,566. Moulding and vulcanizing hollow rubber articles. HUNGARIAN RUBBER GOODS FACTORY, Ltd. Nov. 11, 1937, No. 31051. Convention date, Nov. 21, 1936. Addition to 488,422. [Classes 70 and 87 (ii)] Hollow rubber articles, such as balls, are formed by pressing rubber sheets, without any preforming operation, into the cavities of a bipartite mould by means of a co-operating tool, whereupon stamp-welding of the two halves of the article and vulcanizing are effected in the same mould. The mould halves, which may be hinged together, have one or more rows of hemispherical cavities 3 surrounded by flat ribs 5 projecting from the mould. Connecting ribs are also provided between adjacent cavities. The rubber sheets are pressed into the cavities 3 by a tool 12 having protuberances which are smaller than the cavities by the thickness of the rubber sheet. The sheets are retained in the cavities by suction applied through the channels 14. Raw rubber stoppers 23 and inflating agents are then introduced and the mould halves are closed and subjected to welding pressure. A heating agent is then introduced into the passages 16 to vulcanize the articles which are then taken out and subjected to finishing operations. The two mould halves may be attached to one platen of a press and the die to the other platen or alternatively tools acting simultaneously up and down may be introduced between the two mould halves arranged one above another.

Abstract: 928,550. Winding yarn. E. I. DU PONT DE NEMOURS & CO. Sept. 5, 1961, No. 31848/61. Class 120 (2). A yarn winding process, in which a yarn package 3 is driven by a driving roll 12, includes means whereby the package 3 and the roll 12 are simultaneously moved relatively to a yarn guide 2 on a traverse mechanism such that a substantially minimum uncontrolled yarn length y is obtained throughout the build up of the package, with little change in the yarn break angle 6, and with substantially minimum operable clearance C between the guide 2 and the package 3. In Fig. 4 the yarn guide 2 is reciprocated by a traversing device 16. The package 3 is on an arm 20 pivoted about a first fixed point 21 and the roller 12 is on a plate 22 pivoted about a second fixed point 23. A spring 28 biases the plate 22 clockwise to press the roller 12 against the package. A link 29 pivotally connects the arm 20 to the plate 22. As the package increases in diameter, Fig. 5, it forces the roller 12 and hence the plate 22 to rotate anticlockwise about the point 23 and this movement of the plate 22 is transmitted to the arm 20, by the link 29, such that the arm 20 and hence the package 32 move clockwise about the point 21. The resultant movement of the package 32 is along a path 8 resulting in the aforesaid characteristics relating to yarn length y, yarn break angle 6, and clearance C.

Abstract: 899,506. Valves. PNEUMELEC S.A. Sept. 19, 1960 [July 8, 1960], No. 32148/60. Class 135. In a main valve 20, 21, Fig. 3, controlled by a pilot valve 24, Fig. 2, the pilot valve body B is secured to the main valve body A by a hollow pivot shank 5 acting as a fluid duct and a bayonet joint 8, 9. Energization of solenoid 28 shifts piston valve 24 to the right whereby supply pressure at 15 trapped in passages 18, 29, 7 and 31 closes shuttle valve 20 and opens valve 21 on connected piston 22 since pressure behind the piston is exhausted via 32, 11, and pilot valve passages 33, 34, 35. A jack V is thereby exhausted through passages 14, 17, 16. On de-energizing solenoid 28 and energizing solenoid 27, pilot valve 24 is shifted to the left whereby passages 32, 11 are cut off from exhaust 35 and connected via passages 31, 7, 29, 15 to supply pressure which, acting behind piston 22 to shift it leftwards, closes exhaust valve 21 and opens valve 20 so that supply pressure passes via 17, 14 to the jack V. By turning the pilot body B about its pivot shank 5 to unlock the bayonet joint, the pilot valve may be removed and replaced by one of a different type, e.g. a single solenoid actuating shuttle lift valves (Fig. 6, not shown). The face P-P separating the bodies is sealed by concentric rings 12, 13 between which passes passage 11.

Abstract: 1,104,284. Flexible couplings. WELLMAN BIBBY CO. Ltd. 30 June, 1965 [7 Aug., 1964], No. 32310/64. Heading F2U. In order to provide a stiffness-deflection characteristic in a yielding torque-transmitting coupling of the kind having elastomeric elements between interpenetrating blades on driving and driven members 7, 4, the elastomeric elements are formed with two or more limbs 15 and a connecting portion 16 such that upon application of torque the limbs are initially deflected by bending with respect to the connecting portion so as to progressively increase the area of contact between the limbs or between the limbs and the connecting portion, whereby the limbs and the connecting portion are subjected to an increasing rate of compression and a decreasing rate of bending as the torque increases. The drawing shows three types of element; others are described, including a preferred one of Z-shape. As shown, the coupling is subject to maximum torque and the walls of the blades contacted by the elements which are transmitting torque are substantially parallel. The same elements can be used for couplings of different sizes by varying the number of blades on the driving and driven members.
