Title: Improvements in or relating to bearings
Inventor: PRICE MICHAEL STUART THOMAS
IPC: F16C33/16
Filed: 1952-01-29
Abstract: The pores of a carbon bearing are impregnated with a hard heat-resistant thermo-set resin which is stable and hard at temperature up to 200 DEG  C. and one or more substances selected from the class boric acid and its salts.  Preferably the resin is derived from furfuryl alcohol and/or furfural.  Additionally the bearings may be impregnated with fatty acids having at least eight carbon atoms, or their salts or glycerides.  The impregnating substances may be used simultaneously or in any order.  The bearings may be made by moulding a powder made from coal, coke, carbon black or graphite or mixtures thereof with a bituminous binder, heating the moulded structure to between 800 and 1400 DEG  C. impregnating the product with one or more substances capable of forming a hard, heat-resistant thermo-set resin on heating, and with boric acid and/or a salt or salts of boric acid, and heating to cure the resin. In an example, coke, graphite and hard pitch are mixed at 150 DEG  C. and pressed to form clutch rings. The rings are heated to 975 DEG  C. cooled and impregnated under vacuum with saturated aqueous borax at 100 DEG  C., dried and further impregnated with 4N sulphuric acid. After drying they are finally impregnated with furfuryl alcohol, heated to 150 DEG  C. to cure the resin, and machined.  U.S.A. Specification 1,797,833 is referred to.

Title: Improvements in or relating to electron discharge devices
IPC: H01J17/04
Filed: 1952-01-30
Abstract: 759,255. Cold-cathode tubes. ERICSSON TELEPHONES, Ltd., ACTON, J. R., and REVITT, W. A. Jan. 30, 1952, No. 2458/52. Class 39 (1). An electric discharge tube in which breakdown of the insulation path between internal leads to electrodes due to sputtering is prevented by surrounding the leads by glass cylinders, for example, as described in Specification 750,211, is characterized in that some or all of the said glass cylinders are fastened to the tube by means of a solder in the form of a glass substance of characteristics such that it melts at a temperature at which the cylinders and the adjoining part of the glass envelope of the tube remain substantially solid. In the trigger tetrode shown the anode 1 is formed solely from the internal portion of a stem or lead wire fastened in the base 9 of the containing bulb 8. The tube has a cathode 2 in the form of a molybdenum ring attached to two stem wires 3 which form the cathode lead-out wires, a " light cathode " or " radiant electrode " 5 formed from an arcuate piece of nickel or molybdenum wire welded to the end of stem wire 4, and a trigger electrode 7 consisting of a piece of similar wire attached to the end of stem wire 6. Each cathode lead-out wire 3 is surrounded by a glass cylinder 10 fastened to the base 9 and the anode 1 is surrounded by a glass cylinder 11. One end of each glass cylinder 10 and 11 is flared and then coated with a "glass solder by dipping the flared end in molten lead borate or alternatively the flaring and coating operations may be effected simultaneously by the heated end of a nickel wire tool which has been dipped into powdered lead borate. In assembling the discharge tube, the cylinders 10 and 11 previously shaped and coated as described are fitted over stem wires 3 and 1 and the heat resulting from the process whereby the bulb 8 is sealed to the base 9 is sufficient to melt the glass solder on the cylinders 10 and 11 which sink under their own weight and on cooling are sealed to the glass studs surrounding the associated stem wires. Spacing discs may be employed to maintain the spacing between the cylinders and the surrounded stem wires. The invention may be applied to the cold-cathode diode described in Specification 701,378.
