Abstract: 354,889. Friction blocks. NOVAK, I. J., 73, Whitney Avenue, Bridgeport, Connecticut, U.S.A. May 27, 1930, No. 16344. [Class 103 (i).] Friction elements for friction blocks &c. are made from a fibrous material, such as asbestos pulp or woven fabric, saturated with an oil binder, hardened by heat and pressure. After partial hardening of the elements while they are stacked in a closed pack the elements are spaced apart and the heat treatment is continued in an oxidizing atmosphere, with or without pressure. In a particular example annular ring blanks are stamped out from asbestos mill board, dried and immersed in a bath of china-wood oil heated to 300‹ F. The rings are then removed and allowed to stand at room temperature for from 12 to 24 hours. A coating of fine graphite may then be applied to the rings which are then bolted together in a pack and subjected to a temperature of 400‹ F. for 4 hours. After cooling the rings, which are partially hardened, are separated, hung on spindles and baked in an oven at 325‹ F. for 6 to 20 hours to bring the hardness up to 14 Brinnell. The rings may then be cleaned and shaped for use. Specification 174,685, [Class 103 (i), Brakes &c.], is referred to.

Abstract: 963,503. Pelleting. ALGINATE INDUSTRIES Ltd. May 2, 1962, No. 16462/61. Addition to 762,700. Heading B5A. A modification of the process of the parent Specification for making homogeneous spherical pellets consists in introducing drops of a colloid into an intermediate liquid, which is of different specific gravity from the drops and is also immiscible and non-reactive with them, and thence into a gelling liquid so that the drops become spherical in the intermediate liquid and then become gelled. The colloid (e.g. sodium alginate) is introduced at the bottom of a layer of intermediate liquid 14 (e.g. CCl 4 ) through holes 18 in a tube 17. The drops float across an interface 23 into gelling liquid 15 (e.g. CaCl 2 ) where they become gelled and are removed. The pellets so produced may be used in the manufacture of low density concrete. The pellets are mixed with the concrete and as they contain a high percentage of water on drying the concrete is left with many internal spherical cavities (Fig. 3, not shown). Specification 807,015 also is referred to.

Abstract: 458,394. Hydraulic presses. HULLEN, J. VAN, 82, Hohenzollernstrasse, Krefeld, Germany. June 13, 1936, No. 16567. [Class 69 (ii)] A hydraulic press has a control device for permitting the application of either accumulator or intensifier pressure upon the press ram or drawback piston. Pressure from an accumulator m is directed to the press ram d, Fig. 1, when the lever q of a valve p is in the position I, and to the drawback pistons i when the lever is in the position II. When the lever is in either end position, the lever 3 of a valve x may be turned so that its end 4 moves along a slot 5 or 6 to allow pressure from an intensifier o to act, this pressure closing a check valve 2 in the accumulator connection. The lever q is fulcrumed on the end 4 of the lever 3, and the latter cannot be moved when the lever q is in its mid-position. In a modification, when the lever q is in midposition, the end 4 engages a slot 8, Fig. 4, concentric with the fulcrum of the lever q.
