IPC: F16C33/04
Filed: 1966-07-20
Abstract: 1,138,073. Carbonized cellulose. GENERAL ELECTRIC CO. Ltd. 14 July, 1967 [20 July, 1966], No. 32606/66. Heading C1A. [Also in Division F2] In a bearing arrangement having a bearing component and a rotatable component, at least one of the components, or the bearing surface thereof, is formed of cellulose carbon having a density in the range of 1À2 to 1À6 grams per cubic centimetre. In embodiments the bearing component is formed of cellulose carbon and the rotatable component formed of stainless steel, for example; a cup bearing is formed of cellulose carbon and a rotatable pivot shaft having a hemispherical end is received by the cup bearing, the position of the bearing arrangement being either vertical or horizontal; and the bearing arrangement comprises a sleeve of cellulose carbon and a shaft of steel, for example. A method of manufacturing a cellulose carbon component for a bearing arrangement having a bearing component and a rotatable component, includes the steps of beating a material, consisting of a mixture of cellulose and hemicellulose containing at least 20 per cent by weight of hemicellulose, with water for 4 to 16 hours to form a dispersion of solid concentration 2 per cent by weight, removing water from the dispersion to form regenerated cellulose-hemicellulose pulp and moulding the pulp to form a shaped mass, drying the pulp, heating the resulting mass of dried regenerated material, over a period of 48 to 96 hours, to a temperature of 400‹ to 500‹ C., in nitrogen under a pressure of 300 to 400 atmospheres, to effect partial decomposition of the regenerated material to carbon, and subsequently heating the resulting partiallycarbonized mass under atmospheric pressure to a desired final temperature in the range of 400‹ to 3000‹ C., forming a body of the shape required for the carbon component by machining either the mass of dried regenerated material or the final product of the heating procedure, and polishing the bearing surface of the component resulting from the machining and heating steps. In the manufacture of the cellulose carbon cup bearing, the desired final temperature of the partially-carbonized mass was 1300‹ to 1400‹ C.

Title: Improvements in or relating to signalling systems
IPC: G08B3/10
Filed: 1929-10-29
Abstract: 346,016. Direct-call systems. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm.-(Assignees of Ekman, O. I. H. ; 64, Malmskillnadsgatan, Stockholm.) Oct. 29, 1929, No. 32856. Convention date, Oct. 30, 1928. [Class 40 (iv).] A telephone system is combined with a position marking arrangement for indicating to a central operator the location of a wanted party. As the party required moves from A to B, &c. he marks his position by inserting a plug such as AP, BP into the jack AK, BK, &c. allocated to him, e.g. BK1 at position B. If the operator wishes to locate the party, she depresses and holds MK1. Drive magnet DM drives PV until a circuit is completed to operate VM (in this case over PL2, BK1, OL2) breaking the drive circuit, lighting lamp RL and operating SS. The position of PV indicates to the operator the location of the party. If the operator wishes to speak with the party key EK is thrown upwards connecting ringer VK across the circuit to ring bell BV of telephone BT. The key EK is then moved downwards removing ringing and connecting the operator's telephone in parallel with VM. Key MK1 is released and the switch PV is stepped to normal. When the wanted party replies switch BO changes over and ER energizes, re-operating the drive magnet to step PV. Relay VM pulls up when the called line is reached breaking the drive and the parties can then speak. To originate a call the caller at B removes the receiver to change over BO. ER operates and the arm PV hunts for the calling line over which VM operates to sound SS and light lamp RL.

Abstract: 276,216. Combustion Utilities Corporation, (Assignees of Caplan, S.). Sept. 22, 1926, [Convention date]. Tar oils, purifying.-Tar acid-bearing oils such as low-temperature and blast furnace tars and shale oils, which are suitable for the manufacture of disinfectants, contain impurities of the dihydric phenol type which produce objectionable high colour in the product. Such impurities are dissolved by agitating the oil with an aqueous solution of borax, or the equivalent of boric acid and alkali. The aqueous layer is withdrawn from the purified oil, to which another similar finishing wash is given. The oil may be distilled before or after washing. The borax solution is revivified for re-use by adding a soluble ferric salt such as ferric chloride, and some alkali. The objectionable matter is thus removed as a black flocculent precipitate. Oxidized copperas solution may be used instead of ferric chloride, and the alkali may be added at the same time, or as a separate stage.

Abstract: 305,328. Bussmann, W. Dec. 12, 1927. Addition to 284,309. Stroke, varying; relief devices; combined with other types of pumps.-In a combined high-pressure and low-pressure pump as described in the parent Specification, a valve 33 is arranged in parallel between the pumps, and the valve casing is connected on one side of the valve by a pipe 35 to a chamber 38, and on the other side by a pipe 37 to the same chamber. The chamber 38 contains two connected piston valves 39, 40 mounted on a rod 42 and controlling the ends of the pipes 35, 37 and a pipe 45 opening into the tank in which the pumps are mounted. The valves 39, 40 are held in the position shown by an adjustable spring 44 so that the pressures on the two sides of the valve 33 are equal. If the pressure in the delivery pipe 9 of the high-pressure pump exceeds a certain limit, this pressure acting on the end of the valve 39 through a pipe 46 moves the pistons 39, 40 to the right, closing the pipe 35 and connecting the pipes 37, 45. The pressure above the valve 33 is relieved and the valve opens, releasing the pressure in the pipe 5 through the ports 47. The strokes of the plungers of the high-pressure pump may be adjusted by means of a rotatable cam 48 provided with a number of cam surfaces adapted to engage pins 49 or slots on the plungers during the suction stroke. The cam may be adjusted by arms 52 on a rotatable shaft 51 engaging projections 53 on the cam. The shaft 51 may be adjusted by hand.
