Abstract: 397,119. Gramophone records. WIMMERSPERG, EUGEN, FREIHERR VON, 5, Rue de Langeac, Paris. Feb. 15, 1932, No. 4381. [Class 40 (ii).] A method of making gramophone and like records consists in impressing the sound record proper under heat and pressure on to a thin dried sheet comprising fibrous material permeated with an artificial resin, and thereafter mounting the sheet when cold upon a baseboard. The base-board may consist of pasteboard, cardboard, thick paper or wood. The sound record sheet, which is secured to the baseboard by a water glass solution, may consist of tissue paper, silk paper or the like impregnated with a mixture of resorcinol, #-naphthol, formaldehyde, and alcohol, together with a catalyst such as sodium sulphate. If desired, the sound record sheet may be provided, during the pressure operation, with a backing of untreated paper, such as glazed or parchment paper, and two such backed sheets may be secured to the opposite sides of a base-board in order to form a double-sided record. The sheets on opposite sides of the base-board are so disposed that there is no tendency for distortion of the completed record. When the record sheet is formed of material, such as tissue paper, which is translucent or is rendered translucent by the permeating material, the surface of the base-board may be provided with printed advertising or similar matter. During the pressure operation, the record sheet is supported by a paste-board sheet disposed on the press-table.

Abstract: 1502087 Semi-conductor compounds; gallium arsenide PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 Feb 1976 [12 Feb 1975] 05113/76 Heading C1A A III-V type semi-conductor compound is synthesized from at least one volatile component supplied in gaseous form and at least one component in a liquid mass heated in a horizontal elongate vessel, the liquid mass having a free surface at its upper side where the volatile component is supplied to the liquid mass from the gaseous phase, portions of the liquid mass nearest the wall of the vessel being kept at a lower temperature than portions thereof present at the free surface of the liquid. Suitably, the temperature gradient between the free surface of the liquid and the wall of the elongate vessel is between 5 and 20‹ C. per cm., the temperature gradient in the longitudinal direction of the vessel during synthesis being negligible with respect thereto. In a preferred embodiment, gallium arsenide is made from a liquid mass 2 of gallium and arsenic in vapour form supplied from a store 7 of solid arsenic provided in the same space as the liquid mass. The temperature of the arsenic store is gradually raised to approximately 620‹ C., while simultaneously the free surface of the liquid mass in boat 2 is gradually brought throughout the greater part of its length to approximately 1250‹ C., while the temperature of the wall of the same part of the length of the mass is gradually brought to approximately 1230‹ C., solid gallium arsenide being deposited on the wall. The necessary temperature control is effected by control of heating elements 22 and 21 in the body and cover of the furnace 8 respectively, and distributed over the length of the furnace so that three temperature zones can be formed, viz, a first zone 11 comprising chamber 14 of tube 5 in which the arsenic is heated, a second zone 12 enabling the temperature of a seed crystal 3 of gallium arsenide to be adjusted, and a third zone 13 intended to bring the gallium mass to the desired temperature and after the synthesis of the gallium arsenide to adjust a cooling gradient in the crystallization step. Preferably the temperature of the seed crystal during the heating of the liquid mass is kept lower than that of the greater part thereof and does not exceed 1100‹ C. A rod-shaped single crystal of the semi-conductor compound so made may be grown from the seed crystal in boat 2 while using a temperature gradient in the longitudinal direction of the boat.
