Title: Carbon black product
IPC: C09C1/58
Filed: 1964-02-18
Abstract: A pelletized carbon black, suitable for compounding in elastomers, consists of a fluffy (i.e. non-pelletized) carbon black and an oleaginous pellet-binding material of low volatility which is compatible with and soluble in an elastomer mix.  The individual kinetic particle units of the carbon black are separately coated with a film of the oleaginous material which is present in a quantity of from 1 to 90% of the oil absorption value (defined in the Specification) of the carbon black.  The pelletized carbon black preferably contains from 1 to 15% by weight of oleaginous material. The oleaginous material may be an aromatic rubber compounding oil, for example obtained by solvent extraction from crude petroleum hydrocarbon fractions, a cycloparaffinic rubber compounding oil obtained by solvent extraction from hydrocarbon fractions, a thermoplastic resin, for example rosin, rosin derivatives, phenolic, terpene, coumarone-indene, urea-formaldehyde and melamine resins and lower molecular polystyrenes, used as such, in solution in other oleaginous materials or in a volatile solvent, or a fatty acid, for example oleic, lauric or stearic acid; mixtures of oleaginous materials may be used.  The carbon black may be pelletized in a dry pelletizing process using, for example, a solution of wood rosin in a naphthenic rubber compounding oil; alternatively, the oleaginous material may be added in the form of an emulsion or a water-soluble derivative, for example the ammonium salt of lauric acid, to a water-wetted paste of the carbon black, the mixture being pelletized in a wet pelletizing process and dried at elevated temperature.

Abstract: 398,220. Electric signalling and distant-control systems. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektrieitõts-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) March 7, 1932, No. 6858. Convention. date, March 6, 1931. [Class 40 (i).] In a system in which control and signalling is performed over a wire individual to the apparatus concerned, no current flow occurs except when the wire is actually transmitting signals or controls. A remote switch S is controlled over individual wire L3 and common return wires L1, L2. To move the switch to its off " position T2 is closed and R2 energizes to effect the control, S changing over to open s1 and close s2. When T2 is released, A2 energizes changing over a1, a2 and lighting B2. Si does not operate to sound the alarm as slow release relay V holds open the circuit. B2 indicates that the control has been successfully performed and is extinguished by changing over Q. Should the switch change over automatically from the position shown in the diagram A2 energizes, B2 lights and as V has not been energized, Si energizes and lochs to sound the alarm HU. Si is released by the operation of the hand switch Q1. The system may be fed by either alternating or direct current. Those switches which are normally operated simultaneously are connected to different polarities to equalize the load on the conductors L1, L2.
