Title: Improvements in the preparation of boron nitride
IPC: C04B35/583
Filed: 1958-08-12
Abstract: BN is prepared by passing NH3 through a dispersion or solution of a boron-containing reagent in a molten non-volatile metal salt at 600-950 DEG  C.  The boron-containing reagent is o-boric acid, boric oxide, sodium, or calcium, meta-, or tetra-borates, potassium fluoborate, perborates, or a mixture of CaO and B2O3, or PbO and B2O3 equivalent to the borate.  Metal salts are halides, e.g. chlorides, of Na, K, Ca, Pb, or mixtures.  A stoichiometric excess of NH3 should be introduced through a tube extending below the surface of the melt. The reaction product is solidified, crushed, and leached with water, and may be subsequently leached with dil. HCl.  A continuous process is described where the BN is skimmed from the surface of the melt, and passed to leach tanks, whence the residue passes to a drier.  The leach liquors pass to evaporators, whence the vapours are condensed and returned to the leach tanks, and the residue is returned to the melt.  Alternatively, the residue may again be leached with water and dilute acid to leave further BN residue, and the leach liquors may be evaporated and the residue returned to the melt.  In Example V BaCO3 is also present with B2O3 in the melt.

Abstract: 703,732. Processing photographic roll-films. KEHR, W., and STRAUSS, R. Nov. 14, 1951 [Nov. 25, 1950], No. 26716/51. Class 98(2) In a method and apparatus for processing photographic roll-films, the exposed film is placed in a closable light-tight container and the end of the film is attached to a.core mounted in the container to be rotatable from the outside, and the film, or the part thereof to be treated, is wound in a spiral on the core, and treated while, being repeatedly wound on and unwound, from the core, by turning the core, with the film upon it, backwards and forwards with change of direction of the film spiral. As shown, a film roll is placed in a small chamber 1 attached to a larger treatment chamber 2, and the end of the film is fixed to a core 5. A lid 8 is then put on to exclude light: Core 5 is rotated by a handle outside chamber 2 so that the film is drawn into the chamber and wound round the core. Preferably the film is wound against its inherent curl so that a loose spiral is formed. Ribs. 2a, 8a formed within chamber 2 and lid 8 contact the film at its edges and prevent it from otherwise touching the chamber walls. Treatment liquid may be poured in through a passage 13 before or after winding the film: The core is then rotated in the opposite direction, forming a bend 4a in the film which travels along its length until the film forms a spiral in the reverse direction. This is repeated until treatment is complete. The liquid may then be poured out, and replaced by another treatment liquid, or the film may be taken out and washed and dried, for which purposes core 5 may remain attached to the film to hold it by its weight in an uncoiled position. The film (assumed to be perforated) may pass over sprockets 14 geared to a counter for measuring the length of film wound into chamber 2, and if all the film is not to be treated, when a sufficient length has been wound a clamp 12 is pushed down to,press the film against the partition 10 between chambers 1 and 2.

Filed: 1961-07-31
Abstract: 986,123. Automatic frequency control; automatic gain control. SIEMENS & HALSKE A.G. July 31, 1961 [July 29, 1960], No. 27708/61. Headings H3A and H3Q. In a transmission system wherein a single side band carries a plurality of telegraph channels each operating at a fixed but different frequency, a combined A.F.C. signal or a combined A.G.C. signal is derived at the receiver from at least two of the received telegraph channels. Automatic frequency control, Fig. 1. The received signal at A is filtered at F1, amplified at V1, and, in a mixer M1, the carrier is reinserted by a local oscillator G1, the L.F. modulation products being passed by a L.F. filter F2. The individual telegraph channel frequencies are filtered out at F3, F4, F5, amplified at V3-V5 and fed to frequency discriminators D3-D5, the outputs of which are combined at MS, e.g. added (or the instantaneous largest may be selected) and serve to adjust the frequency of oscillator G1 until each of the telegraph signals fed to filters F3-F5 equals that of the centre of the pass-band of the respective filter. In a modification, Fig. 2 (not shown), wherein the receiver FE is remote from the telegraph equipment, the receiver output is fed to an additional local circuit where it passes through two frequency changing stages, the A.F.C. signal controlling the local oscillator in the second of these stages instead of that in the receiver. Automatic gain control, Fig. 3. At the receiver FE the carrier is reinserted in a mixed M1 by an oscillator G1 and a filter F2 passes the L.F. modulation products. These include a speech channel which is filtered out at F8 and telegraph channels which are filtered out at F9, amplified at V7 and passed to the individual telegraph channel filter F3-F5, the outputs of which are amplified at V3-V5. Control voltages derived from these amplifiers are either combined in a mixer MS or else the maximum instantaneous control voltage is selected, and fed back as an A.G.C. signal either to the amplifier V7 or V1. A.F.C. may also be effected as previously described.
