Abstract: 1,043,172. Electric incandescent lamps. GENERAL ELECTRIC CO. June 7, 1963 [June 18, 1962], No. 22814/63. Heading H1F1 An electric lamp comprises an outer glass bulb 1 having a neck, an inner envelope 3 consisting of a single unitary length of glass tubing have a closed inner end and sealed to the neck of the outer bulb at its outer end, the inner envelope having a single pinch seal portion 7 between the ends forming an inner chamber 8 in which is a filament 9 carried by a pair of lead-in conductors 10, 11, passing through the seal. The chamber 8 may have a filling of inert gas and a halogen such as iodine. In making the lamp, a button is first upset on the end of an exhaust tube 12 and an intermediate filament support is sealed thereon. Lead-in wires 10, 11 are then arranged on opposite sides of the tube and a filament 9 secured between them, the end of the intermediate support wire being looped round the centre of the filament. A glass tube 3 is then slipped over the assembly and heated by burners, in the vicinity of the end of the tube 12, the tube 3 being sealed by compressing the heated area in a pair of relieved jaws to avoid closing the tube 12, a flow of inert or reducing gas being maintained through the tube 12 durng heating to avoid oxidation of the filament and supports. The tube is then exhausted and filled with inert gas, e.g. argon, krypton or xenon, and a small quantity of iodine vapour, the tube 3 being inverted and the lower end cooled to condense the vapour during this process. The seal area 7 is then heated and closed and an aperture 14 opened from the exhaust tube to the outside of the tube 3. The tube 3 is then sealed at the neck into the outer glass bulb 1, which is then evacuated and gas filled through the exhaust tube 12 which is finally tipped off. In a modification, the closed upper end of the tube 3 may have an exhaust tube sealed to it, the exhaust tube 12 being used only for exhausting and gas filling the outer bulb.

Title: Improvements in or relating to thermoplastic compositions and mouldings having a cellulose derivative basis
IPC: C08J3/205
Filed: 1935-08-14
Abstract: A powdered, granular, or fibrous cellulose ester or ether is impregnated with an aqueous metal salt solution, and the cellulose derivative which is freed from or carries only adherent metal salt solution, is subjected to treatment with an aqueous reagent to fix the metal in the cellulose derivative in the form of a waterinsoluble compound wholly mineral in character, and the individual particles, granules, or fibres are thereafter coalesced.  Suitable metal salts are stannic chloride, and compounds of barium, tungsten, zinc, aluminium, or lead, and the solutions of these salts may be applied to the cellulose derivative while the latter is in a swollen condition.  The metal is preferably precipitated by means of a solution of a phosphate, p  an alkali hydroxide, or carbonate, and a final treatment with a solution of a silicate may follow.  The cellulose derivative in the form of powder, granules, or fibres, if desired, after incorporating plasticizers, fire retardants, solvents, pigments, or dyes, is coalesced under the action of heat and pressure. These may thus be formed by rolling, moulding, or extrusion moulding, sheets, coated fabric, combs, mirror handles, tooth brush handles, pencil or pen barrels, phonograph records, telephone receivers, and electrical apparatus.  In an example, cellulose acetate in filament, fabric, or powder form, is impregnated with a solution of stannic chloride containing formic acid, rinsed in cold water, entered into a solution of disodium phosphate, rinsed, entered into a solution of sodium silicate, washed, dried, mixed with a swelling agent such as acetone, and moulded under heat and pressure. In a second example, powdered cellulose acetate is treated with a solution of stannic chloride, washed, treated with sodium silicate, washed, dried, and mixed with a plasticizer by agitation in aqueous suspension. Specifications 258,874, 259,899, 260,290, 270,987, 272,982, 281,084, 284,798, 285,941, and 309,876, [all in Class 2 (ii)], are referred to.

Class 60. In apparatus for grinding or polishing a sheet of glass 1 the rubbing element 2 has imparted thereto a circular translatory motion by giving to at least two of its points A, B movements of rotation of the same radius and of the same phase, the element being movable towards or away from the sheet of glass under the action of pivoted arms 23 controlled by a common central element 13 capable of being displaced in a direction perpendicular to the sheet of glass. The element 2 is integral with cylindrical members 34 having axes Y-Y which. rotate about axes X-X when members 26 are driven through splined connections 29 by electric motors (not shown). An endless chain 40 couples the two members 26 so that they rotate in synchronism. Each member 26 is carried by a sleeve 4 integral with a piston-like portion 7 which may be subjected to the action of compressed air to move the element 2 towards the glass sheet 1. The extent of this movement is limited by the engagement of the element 13 with a flange 18 on a nut 17 which may be lifted by a motor-driven screw 10 to allow the element to descend. The circuit for the motor includes a pair of contacts 22, one of which is carried by the nut 17 and the other by the element 13. Once the element 2 engages the glass, the element 13 ceases to move upwards and the motor-driven screw 10 continues to rotate until the contacts 22 separate. The pivots 24 for the arms 23 are eccentrically mounted so that the element 2 may be adjusted for parallelism with the glass sheet 1. If the element 2 is to be detachable, it is mounted in slideways in the frame of the apparatus and provided with recesses to engage frusto-conical bosses on the ends of the members 34.
