Title: Ozone manufacture
IPC: C01B13/11
Filed: 1956-03-19
Abstract: 785,671. Producing ozone. AIR REDUCTION CO., Inc. March 19, 1956 [March 21, 1955], No. 8490/56. Class 39(1). Ozone is produced by subjecting hydro. carbon-free oxygen tc a glow-type electrical discharge, separating immediately the ozone from residual gases by condensing the ozone, removing the residual gases and collecting the condensed ozone. Commerical grade oxygen is purified to remove hydrocarbon impurities, water and carbon dioxide by treatment in a combustion tube furnace and is then passed by line 23 through diptubes 55, 57, cooled by liquid nitrogen 69, into the conversion zone 65, 67 of the ozoniser where it is subjected to a glow-discharge between electrodes 61, 63, the ozone so formed condensing immediately at the temperature of the liquid nitrogen and collecting in the bulb 85. The residual gases and unused oxygen are drawn off through outlet 81 and bleeds 75, 77, the flow through the two bleeds serving to cool the electrodes 61, 63. The liquid ozone may be drawn directly from the bulb 85, or the discharge may be stopped, the liquid nitrogen bath removed, and the ozone drawn off as a gas at line 81. For efficient condensation the internal diameter of the U-tube 65, 67 should be 5-12 mm. Preferably the oxygen is introduced at a pressure of less than 1 mm. mercury and the discharge is operated near its point of extinction, an electron density of between 6À0 and 8À5 ma/mm. mercury pressure being desirable. Alternatively the oxygen may be introduced at the foot of the U-tube and the residual gases extracted at the upper end.

Patent GB-138946-A (GB)
Title: Improvements in or relating to the purification of zinc solutions
IPC: C01G9/06
Filed: 1918-05-22
Abstract: Zinc solutions, such as zinc sulphate, are purified for electrolysis by treatment with ozonized air in presence of a metallic oxide, hydrate, or carbonate, manganese dioxide, manganese hydrate, lead and zinc oxides and carbonates, and zinc hydrate being mentioned as suitable.  The treatment is preferably effected at a raised temperature and with agitation.  If the zinc solution contains manganese, an added reagent is not necessary, and the manganese compound may be caused to precipitate by adding a reagent such as chalk or zinc oxide.  Any manganese remaining in the solution after purification is recovered as peroxide mixed with lead peroxide as an anode mud in the electrolysis, and this mixture may be used as the catalyst.  The treatment described removes iron, cobalt, arsenic, and antimony; but copper, nickel, and cadmium are not completely precipitated.  These metals are finally removed by treatment with zinc dust as described in Specification 138,947, or with zinc dust in presence of acid, as described in Specification 138,954.

Abstract: 401,947. Kinematograph apparatus. LANGE, E., 115, Spandauerstrasse, Zehlendorf, Berlin. March 22, 1933, Nos. 8656, 8657, 8658,8659, and 8660. Convention dates, March 23, 1932, July 15, 1932, Aug. 24, 1932, Sept. 30, 1932, and Feb. 7, 1933. [Class 97 (i).] Endless films are loosely coiled in a holding device comprising feeding elements which clamp the convolutions firmly together in one part of the coil, so that they are fed without relative displacement, and permit the remainder of the convolutions to be spaced apart so that relative displacement may take place between them without rubbing. As shown in Fig. 1, the coil 1 is clamped between supporting rollers 2, arranged in a straight line, and rollers 3 pressed against the film by springs 6. Lateral rollers 5 may be provided, and may have projections which effect feeding by engaging notches in the film edges between the perforations. The film passes through slits in a casing 19 to and from rollers 4, 12 and a projector. Pairs of rollers may be provided which twist the film through a right angle between the rollers 12, 14, and means is described by which one of the members of one pair is moved by springs, if the film breaks, to tilt a mercury switch and break the motor circuit. The rollers 2, 3 may be replaced by endless belts 39, 40, Fig. 6, and the belts may be formed of plates hinged together with pins 41 which project from the ends of the plates to engage in notches 43 in supporting and driving discs, and to ride on lateral guide plates 42. The plates may be covered with rubber, silk, &c. or the belts may be made of rubber, 60, Fig. 10, guided by rollers 64 and tensioned by a roller on a spring-pressed lever 63. The rollers 5 may be replaced by lateral plates 45 carrying rollers 45<1>, 46. Long films may be divided into two or more coils carried by a common belt. The film openings in the casing of the film holder may be provided with endless bands 84, 85, Fig. 13, of metal or other fireproof material carried by rollers 80...83 to render the casing fireproof. The rollers 82, 83 are carried on fixed shafts in a channel in the casing, and the rollers 80, 81 are pressed on to the film 92 by a spring 91 bearing on their shafts. Suction nozzles 94 connected by pipes to a fan, or brushes or wipers, may be arranged at the ends of the bands 84, 85 to remove dust &c. from the film. A construction of holder is described in which the film is coiled in a horizontal plane, is supported on rollers, and is driven, through bevel gearing, from a driving pulley. The film may be loosely coiled in the holder by winding it therein in conjunction with a spacing strip, and, after connecting its ends, winding the film to remove the strip. Alternatively, the film, wound into a coil with a spacing strip incorporated, may be placed in position in the holder, the strip being afterwards wound from it.
Patent GB-933707-A (GB)
Title: Improvements in or relating to apparatus for defining predetermined instants in a binary signal sequence
IPC: H04B14/06
Filed: 1961-03-09
Abstract: 933,707. Pulse modulating systems. TELEFUNKEN G.m.b.H. March 9, 1961 [March 12, 1960 (2)], No. 8658/61. Class 40 (5). In a synchronizing arrangement for a pulse code modulation system a predetermined sequence of binary signals is inserted at regular intervals in the coded signal series, said predetermined sequence being divided into a preliminary sequence and a final sequence having a smaller number of digits than the preliminary sequence, the coincidence of the final sequence with the setting of a register being utilized for synchronizing when the presence of the preliminary signal has been detected. As described the preliminary signal is the 32-digit sequence 101010 . . . . and the final or " tripping " signal is the sequence 1001. At the receiver the incoming pulse signals are supplied via terminal 1 to a device 2 which produces a potential on lead 3 or 3a dependent on whether the signal at that instant is a " 1 " or " 0." A pulse generator 4 generates pulse trains T, T 1  which are synchronized in known manner with the incoming signal pulses by a phase-comparison circuit 5. The pulses T are fed to a shift register comprising flip-flops 7 to 10 whose outputs are connected to a coincidence gate 11 in such manner that the tripping signal will cause four coincident pulses to appear at the gate 11. An OR-circuit 15 is connected to the output of the shift register element 10 and applies a pulse to set a bi-stable device 16 whenever the signal at 10 has changed from " 1 " to " 0 " or from " 0 " to " 1 " as during the preliminary synchronizing signal, the time-shifted pulses T 1  being supplied to the other input of the bi-stable device 16. The pulses T 1  also control a counter 14 which is arranged to count either forward one or backward two according to whether the bi-stable device 16 is set to " 1 " or " 0 " just before the arrival of a pulse from the OR-circuit 15. The counter is such that it will only count as far as zero in the backward direction. When the counter has made a count of 32 it applies a pulse to a switching device 13 and a pulse lasting for the duration of several digits is supplied as a coincidence signal to the gate 11. If a short alternating type of signal should occur immediately before the correct preliminary signal the lengthening of the pulse from 13 causes it to be maintained at the gate 11 until the tripping signal has reached the register 7 to 10. An arrangement suitable for the counter 14 and its changeover device is described, Fig. 3 (not shown). The arrangement is applicable to a delta modulation system transmitting a difference signal in which it is required at predetermined intervals to transmit a signal giving an indication of the signal amplitude.
