Title: Improvements in or relating to the manufacture of glass
IPC: C03B5/185
Filed: 1946-09-03
Abstract: 616,451. Glass manufacture. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY, & CIREY. Sept. 3, 1946. No. 26503. Convention date, Sept. 15, 1945. [Class 56] [Also in Groups XI and XII] The fining zone of a bath of molten glass is heated by association of heat from a source above the bath with heat generated by passage of electricity between electrodes which penetrate the bath bottom at points distant from the lateral walls and are restricted to the lower part of the bath, so that they and the walls are not attacked by the hottest glass and do not cause colouration. As applied to a continuous furnace wherein raw materials are supplied through an aperture 2 to a melting zone 4 leading directly to a fining zone 5 whence the glass passes beneath a partition 8 to a cooling and working zone 6 having extraction apertures 3, the electrodes 9 beneath the fining zone are relatively short and are located near the centre line of the bath bottom; electric resistances may be arranged above the bath, or transverse heating may be provided by lateral burners 10, 11, 12. The melting zone 4 may also be heated by the latter as shown, or a heating current may be passed therethrough.

Abstract: 921,887. Determining the moisture content of steam. VYZKUMNY USTAV ENERGETICKY PRAHA. July 30, 1960, No. 26621/60. Class 97 (3). Steam passing through a conduit is induced by means of an injector to enter a detector 1, or controlled in its entry by means of a valve, not shown, at the exit 11 of the detector 1, according as the pressure of the steam is less than or greater than atmospheric, the detector having a heated surface 8 which is maintained at a constant temperature difference above that of the moist steam so that the heat input to the heated surface, in excess of that which would be necessary if dry steam entered the detector 1, is a measure of the heat utilized in evaporating the moist steam and is thus a measure of the moisture content thereof. The detector 1, which is in the form of a cylindrical tube, is provided with means 2, 4 to measure the pressure inside and outside the tube 1 respectively and thermocouples 6, 9, for measuring the temperatures of the moist steam and the heated surface 8 respectively. The heat supplied to surface 8 is controlled by potentiometer 15 and measured by a wattmeter 14. The surface 8 may be a directly heated grid, as shown, through which the steam passes or a surface, around which the steam flows, heated by a spiral exposed on its front surface or embedded therein. An auxiliary coil may be provided on the sides of the heated surface to prevent loss of heat by conduction from the front surface.

Cellulose ethers, processes for making filaments and films from.-For the coagulation of the cellulose ether films, bands, threads, &c. there is used a hydrocarbon which is readily mixible with the solvent or solvent mixture of the cellulose ether solution but which does not dissolve the cellulose ether. As the solvent there mav be used carbon disulphide or mixtures rich in carbon disulphide, or ethyl ether alone or mixed with other solvents. Suitable hydrocarbons are paraffin oil, petroleum jelly, and other high boiling point fractions of petroleum; petrol, shale oil, and hydrocarbon fractions of Bergination oil. The products are subjected to mechanical treatment to remove the adhering hydrocarbon, the last residues being dissolved by washing or being allowed to evaporate. In examples, paraffin oil is employed as the coagulant, and the cellulose ether is dissolved in a mixture of carbon disulphide and ethyl ether, butanol or benzene or in a mixture of ethyl ether and benzine. Films, &c. so made, are repellant to water.

Abstract: 1371687 Hologram KMS INDUSTRIES Inc 9 June 1972 [9 June 1971] 26954/72 Heading G2J The signal beam and reference beam are scanned across the width of a film 20 by a rotatable mirror turret having a series of facets 64 all at the same angle for the signal beam, and a second series of facets 1, 2, 3 set at individual angles. Thus each successive sweep is characterized by a unique reference beam angle and read-out is possible even if the sweeps overlap. The film meanwhile is continuously moving and thus the sweeps record across the film at an angle. To read, either an appropriately angled reference beam is used, or an unmodulated "signal" beam can be used and a multiplicity of detectors employed, one for each facet of the turret.

Abstract: 1,010,210. Microwave attenuators; semiconductor devices. GENERAL ELECTRIC CO. Ltd. Oct. 11, 1963 [July 13, 1962], No. 27015/62. Addition to 996,821. Headings H1K and H1W. [Also in Division H3] A variable attenuator comprises a microwave hybrid circuit, e.g. a magic-T as shown, having an input arm 1, an output arm 4 and two further arms 2, 3, each containing a P-I-N junction diode 7, 8 in shunt with a dissipative load 5, 6. A variable bias is applied to the diodes. As shown, the arms 2, 3 comprise the co-linear arms of the magic-T. The electrical distances of the diodes 7, 8 from the junction differ by a quarter-wavelength at the operating frequency so that the equal portions of input energy reflected by the diodes return to the junction in antiphase and are coupled into the output arm. When the diodes are in the non- conducting condition, substantially the whole of the input energy is absorbed by the loads 5, 6. The attenuation is stated to vary linearly with the voltage applied to the diodes. The invention may also be realized using a directional coupler or a ring hybrid in the manner described in Specification 996,821. A number of diodes spaced by half-wavelengths may be used to replace the single diodes. The P-I-N diode used in the embodiment includes a wafer of silicon doped with phosphorus, the P-region being formed by alloying aluminium with one main face of the wafer and the N-region by alloying gold, containing a small percentage of antimony, with the opposite main face. The I- region is only near-intrinsic and has a resistivity in the range 100 to 500 ohm-cm.
