Title: Improvements in or relating to apparatus for photoelectrically exploring sound records
IPC: G11B7/00
Filed: 1937-10-05
Abstract: 503,232. Optical sound - reproducing apparatus. ZEISS IKON AKT.-GES. Oct. 5, 1937, No. 26999. Convention date, Nov. 23, 1936. [Class 40 (ii)] Apparatus for the reproduction of sound records in which the positive and negative half-waves are recorded separately comprises two photo-cells and an amplifying valve controlled by and common to the cells, the latter having their anodes connected to a common source of anode potential and being connected in their output circuit in opposed aeries relation-' ship. As shown, the double photo-cell 2 having a common cathode 3 and two anodes 4, 5 is connected through coupling condensers 6, 7 and resistances 8, 9 to the amplifier valve 1. Resistances 10, 11 serve to apply the anode potential, supplied through the lead 12, to the cells. If desired, separate potentials may be applied to each of the anodes through the resistances 10, 11 and by making these potentials adjustable, a convenient means of equalizing the sensitivities of the two halves of the cell is provided. Alternatively, adjustable light-absorbing devices may be disposed in the light path of the cell. In operation, under the influence of the light impulses from the record, each of the anodes 4, 5 will in turn become more positive than the other with respect to the cathode, so that assuming that the summed impedances of the parts 7, 9 and of the parts 6, 8 are considerably less than the resistances 11, 10 respectively, an alternating potential will be set up across the resistances 8, 9 and accordingly across the grid and filament of the valve 1. The two component cells of the double photo-cell 2 are connected in opposed series relation as regards their output circuit, i.e. the arrangement of the cells in the output circuit is anode-cathode-cathode-anode.

Many examples of specified radicals are given. The dye precursor may be prepared by many conventional methods, for example by condensation of 4-(4<SP>1</SP>-aminophenyl)- pyrylium salts with ammonia or agents which disengage ammonia or by condensation of a 4-aminobenzaldehyde of the general formula or an arylvinylketone of the formula with a ketone of formula in the presence of ammonia or an agent which disengages ammonia. A list of preferred starting materials are given. In one example for the preparation of the dye precursor, pyridine, benzoyl chloride and copper powder are heated for an hour at 100-105‹ C. Methylbenzylaniline is added at 70-80‹ C. and heating at 100-105‹ C. continued. Toluene is added, the resultant precipitate being dissolved in hydrochloric acid. After clarification and recrystallization from ethanol and water, 4-(4<SP>1</SP>-methylbenzylaminophenyl)-pyridine is obtained. In a second example, p-dimethylaminobenzaldehyde, acetophenone and ammonium acetate are heated under reflux in glacial acetic acid. The precipitate is recrystallized from ethanol being 2,6-diphenyl-4-(41-dimethylaminophenyl)-pyridine.  The 4-(4<SP>1</SP>-aminophenyl) pyridines may be mixed with another dye precursor, e.g. crystal violet lactone, N-phenyl leucoauramine, N- benzoyl-leucomethylene blue and, in dissolved form micro-encapsulated. The capsules are applied together with a binder to paper. A visible trace on another, acidic, surface results when the capsules are ruptured by pressure.

Abstract: 1440123 Automatic voltage control SIEMENS AG 11 June 1973 [16 Oct 1972] 27667/73 Heading G3R [Also in Division H4] In an arrangement for measuring a dimension of an object utilizing the time required by the beam of a television camera tube to scan an image of such object projected on to the target of the tube, the peak amplitude of the scan control current is stabilized at a predetermined level. This arrangement compensates for variation produced in the deflection circuitry due mainly to thermal effects and thus improves the accuracy of measurement. As shown, the object 2, which comprises the melt zone produced during a non-crucible zonemelting process of a semi-conductor, is imaged via an optical system 12 on to the target 13 of a vidicon television camera tube the beam of which is scanned in the horizontal direction by a horizontal scanning coil 11 and the video signal output of which is utilized in a processing circuit 3 to produce the required measurement. To maintain the peak value of the horizontal sawtooth scanning current from generator 4 at a predetermined level, a series resistor 5 develops a voltage proportional to the scanning current and this voltage is supplied via an amplifier 6 to a peak rectifier 7 the output of which is compared with a pre-set reference voltage from potentiometer 8 in a comparator from which an output is supplied via an amplifier 9 and switch 10 to known peak level control circuitry in generator 4. The opticalelectric conversion scale factor of the arrangement may be adjusted by adjustment of potentiometer 8. Switch 10 may, alternatively, select a manually adjustable pre-calibrated potentiometer for calibration purposes or in the event of failure of the control arrangement.
