Title: Method and apparatus for manufacturing glass spheres
IPC: B01J2/06
Filed: 1975-10-28
Abstract: 1506243 Glass spheres TECHNION RESEARCH & DEVELOPMENT FOUNDATION Ltd 28 Oct 1975 44456/75 Heading C1M A glass sphere is made by allowing a drop of molten glass (e.g. from melting furnace 1) to sink through a tubular column 3 filled with a liquid 5 which has a specific gravity 0À05-0À2 less than the molten glass and which is substantially inert to the glass, the temperature of the liquid 5 being so graduated that the drop cools slowly to a temperature below its annealing point on completion of its passage through the column 3, so that the sphere is precisely spherical and hardened sufficiently to be handled. The liquid 5 (which is supplied to the column from reservoir 6) may be a molten mixture of inorganic salts (e.g. NaCl/ZnCl 2  or in which case the temperature may be graduated from 750 C. at the head of the column 3 to 380 C. at its foot. The reservoir 6 and column head may be heated by resistance heater 13. To facilitate removal of formed spheres, the column 3 is bifurcated, the cooling cuffs 7 and 9 being operated alternately to block the corresponding tube with a plug of solidified salt and direct glass spheres to the other tube. Formed spheres are removed through the outlet 11 of the blocked tube. The apparatus is preferably formed of a Ni/Cr/Fe alloy.

Patent GB-446055-A (GB)
Abstract: 446,055. Anti-aircraft gun sights. NAAMLOOZE VENNOOTSCHAP NEDERLANDSCHE INSTRUMENTEN COMPAGNIE NEDINSCO, 9, Molensingel, Venlo, Holland. July 29, 1935, No. 21443. Convention date, Aug. 4, 1934. [Class 92 (ii)] Relates to apparatus for calculating and applying to anti-aircraft guns the lead corrections in elevation and azimuth for speed of target and of the kind in which the target is followed by a sight 2 driven by a constant-speed motor 24 through a handadjusted change-speed gear 19, 20. According to the invention, a second change-speed gear 22, 23 is provided for controlling the angular speed of the driving member 20 of the first change-speed gear in accordance with the reciprocal of the time of flight, the radial movement given to the driven member 19 by adjusting the handle 12 in following the target is then a measure of the required lead. Fig. 1 is a diagram showing the angles involved in correcting the elevation for a target flying from Z to T. The apparatus for giving continuously the corrected elevation #T is shown in Fig. 2. By rotating the handle 12 with clutch 16 disconnected, a shaft 5 is rotated to elevate the sight 2 about the axis Y-Y, and by moving the whole apparatus about an axis X-X the sight is brought on to the target. By engaging the clutch 16 and adjusting the handle 12, the telescope is driven by the motor 24 through the change-speed gears, shaft 9, and differential gear 7 to follow the target continuously at an angular velocity w, the shaft 9 rotating proportional to this velocity. The disc 20 is rotated proportional to 1/t, where t is the time of flight, by displacing the roller 22 relatively to the disc 23 by means of a rack 28 moved by a cam 29. The cam is rotated proportional to target elevation gammaT and translated proportional to range ET. The shaft 17, in setting the roller 19 relatively to the disc 20 to cause the shaft 9 to rotate proportional to w, must therefore rotate proportional to the product wt. The rotation of the shaft 17 is conveyed to one side wheel 39 of a differential gear the other side wheel 43 of which rotates proportional to the present elevation gammaM. The planet wheel 37 then rotates the shaft 31 proportional to (gammaM+wt)=gammaT which is conveyed to the gun. The Specification describes the use of the apparatus in applying the lead correction in azimuth.

Abstract: 1,197,642. Semi-conductor devices. HITACHI Ltd. 13 Oct., 1967, No. 46849/67. Heading H1K. During the manufacture of a semi-conductor device metallic particles having a predetermined electric potential relative to a semiconductor substrate are deposited on an insulating coating on the substrate while the latter is heated to above 75‹ C., the preferred temperature range being 200-600‹ C. Such treatment reduces the effect of the inversion channel beneath the insulation and thus produces relatively stable devices. The invention is described particularly with respect to silicon MOS capacitors, the deposited metal particles being of Al, Cr, Ti or Ag, evaporated in vacuo from a source held at a fixed potential relative to the substrate. For P-type silicon the evaporation source, and hence the deposited metal, is preferably held at a negative potential relative to the substrate. The invention includes the case in which the deposited metal and the substrate are at the same potential. Removal by etching of the deposited metal particles does not interfere with the advantage gained by the method of the invention. As well as silicon oxide the insulating layer may be of silicon nitride or of a vitrified material comprising phosphorus oxide and silicon oxide produced by heating a silicon dioxide layer in an atmosphere containing POCl 3 . The invention may also be applied to a planar bipolar transistor, a charged evaporated Al coating over an apertured oxide layer being etched away from all regions except those required to form emitter and base electrodes and an annular region enclosing these electrodes.
