Title: Improvements in and relating to electrical systems for the photographic recording of electric oscillations and/or for sound recording
IPC: G11B7/00
Filed: 1936-08-31
Abstract: 467,711. Optical sound - recording apparatus. KOLB, O. K. (Beer, P. F.) Aug. 31, 1936, No. 23770. [Class 40 (ii)] The sensitivity of an electrostatic oscillograph is varied automatically in dependence on the intensity of the sound undulations so that the amplitude of movement of the oscillograph may not exceed a maximum value consistent with distortionless recording. In one form, the output of a valve U into the primary P of a transformer is passed by the secondary Sl, S2 to the oscillograph O, the stationary electrodes a1, a2, a3, a4 being connected to the ends of the secondary and the mirror electrode b being connected through condensers to the centre point of the secondary. Bias is applied to the oscillograph by a battery Q through resistance R4 on the positive side, and through resistance R3 on the negative side. The resistance R4 is in the anode circuit of a control valve B, the grid of which is negatively biassed through a resistance R2 and receives oscillations from the transformer primary P. When the oscillations exceed a given value, current flows in anode circuit of control valve B causing a drop of voltage in resistance R4 whereby sensitivity of oscillograph is reduced. The action of the control valve B depends on the voltage to which the grid and cathode of the valve are connected, and a rectifier W1 may be added between the grid and a suitable point of the battery to fix a limit to the anode current of the control valve B. An additional valve A may be provided to displace the zero of the oscillograph for noiseless sound recording. The grid of this valve is fed from the transformer primary P by the system of condensers C5, C6, resistances R6, R7 and rectifier W2. The anode of the valve is connected to the oscillograph circuit by means of resistance R8 and condenser C2. In a modification, the valve A is omitted, and the circuit consequentially modified. In another modification, a pushpull output valve is used to perform the functions of both valves U and B.

Abstract: 819,710. Photographic processing methods and apparatus. WINNEK, D. F. July 29, 1957, No. 23958/57. Class 98(2) Processing liquid is supplied to a predetermined level of a tank holding exposed prints, which tank may have a light-tight cover and may be accommodated in a drawer of a cabinet holding other requirements of the invention, supply and removal of the liquid are continued at the same rate to produce turbulence within the tank for the processing, and the supply is discontinued but removal maintained until the tank is empty; the removal operations involving return of the liquid to a reservoir from which it originated, thus providing a period of continuous circulation. This liquid may be developer and its use may be followed by a treatment with washing water supplied similarly but removed to waste, then by a circulation of fixer and finally by a longercontinued washing treatment. Drying air may then be impelled through the tank by features first used to effect the liquid supply and removal. As shown in Fig. 5 the liquid is supplied through inlet 53 past baffle shell 55 to the height of level-controlling probe 58 above films carried by hangers 36 in tank 35, and then further liquid begins the circulation through outlet 54. Part of the liquid may enter the tank through spray nozzles 45 directed to the films. In Fig. 9 for the liquid circulation 61, 62, 70, 72, 79, 81, 83 and 85 are solenoid operated valves for an electrical circuit of Fig. 12 (not shown) to cause time controlled liquid circulation by pump 34 including washing of all pipe portions used and also the pump itself after the developer and the "hypo" treatments.

Abstract: 885,673. Purifying gas; treating ammoniacal liquor. KOPPERS CO. Inc. July 13, 1959 [Aug. 18, 1958], No. 23966/59. Drawings to Specification. Class 55 (2). In a process for treating crude coal distillation gas the gas is first cooled to condense tar and aqueous condensate before being de-tarred in an electrostatic precipitator and the de-tarred gas is then washed first with a wash oil to remove naphthalene and then with water to remove ammonia, the ammonia containing liquor being passed to a still where it is stripped of free ammonia which is burnt in the presence of air and steam under temperature and heat evolving conditions precluding the formation of oxides of nitrogen and the combustion products discharged to atmosphere. The wash oil for removing naphthalene may be a petroleum oil boiling between 300 and 378 C. or a tar distillate boiling between 200 and 400 C. Hydrogen sulphide and cyanide in the gas absorbed in the washing to remove ammonia are also removed from the liquor and burnt together with the ammonia. To increase the amount of hydrogen sulphide and cyanide removed by washing the gas with water, the liquor therefrom may be treated in two stages, in the first a portion of the free ammonia and all the absorbed hydrogen sulphide and cyanide are removed and burnt and in the second the remaining ammonia is removed and returned to the step in which the gas is washed with water. In the burning of the ammonia the water vapour to ammonia ratio ranges between 3.7: 1 to 1: 1 and the temperature of the vapours supplied to the chamber in which the ammonia is burnt is maintained in excess of 70 C. to prevent formation of ammonium carbonate. The temperature in the combustion chamber is maintained between 760 and 980  C. and the residence time of the gases in the combustion chamber such that there is a heat release of between 20,000 and 130,000 B.Th.U per hour per cubic foot of combustion volume.
