Title: Improvements in or relating to photographic cameras with polarisation devices
IPC: G03B17/12
Filed: 1937-04-09
Abstract: 492,820. Photographic cameras with polarizing screens. ZEISS IKON AKT.- GES. April 9, 1937, No. 10196. Convention date, April 23, 1936. [Class 98 (i)] One or more screens are mounted on or in the camera so that any screen is movable either into a position in front of the camera objective, or into a position in which the object can be observed through it, without altering its direction of transmission relative to the object. In one form, Fig. 1, a screen 4 is mounted in a holder 5 angularly adjustable in an arm 3 pivoted to the camera on an axis 2 so that it may be swung from the dotted-line observation position, in which the screen is angularly adjusted to the desired setting, to the full-line taking position in front of the objective 6. In a modification, the screen holder 5 is rotatably mounted in a carrier which slides into the camera from an outside observation position to a taking position behind the objective. In a further modification, Fig. 6, a disc 15 carrying two or more screens, each set with its direction of transmission at a different angle to the line joining its centre to the centre of the disc, is pivoted inside the camera, so that, after choosing the most suitable screen by observation through the finder 21, the disc may be given a 180‹ turn by the knob 20 to bring this screen into the taking position behind the aperture 14. Colour filters may be associated with the polarizing screens. Specification 485,802 is referred to.

Abstract: 385,168. Valve generating and amplifying circuits. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and EBERHARD, H., 27, Rankestrasse, Lichterfelde, both in Berlin. April 9, 1932, No. 10223. Convention date, April 10, 1931. [Class 40 (v).] A crystal-controlled valve oscillator 'has its plate current supplied from the secondary coil 9 of an induction coil 7, the primary coil 6 of which is fed by the filament battery 5 or other low-voltage source, and includes a vibrator 8 for interrupting the primary circuit. The tuned plate circuit of the oscillator is coupled to an aerial 15, and its grid circuit includes a choke 13 and a piezo crystal 12 for controlling the frequency. The oscillations generated are modulated at the interrupter frequency, and reception may be effected either on this note or by the heterodyne method. The circuit may be used for transmitting meteorological readings from balloons. For instance, a thread attached to the vibrator reed may vary the interrupter note according to the humidity of the air. Air pressures, or water depths, may be similarly signalled to a distant point, the pressure varying the note by mechanically or magnetically affecting the interrupter. The transmitter may be used for telephony, the interrupter then operating at a supersonic frequency. When a valve circuit used for receiving or amplifying radio signals is associated with the oscillator, the alternating voltage at the secondary coil 9 is rectified and smoothed before applying it to the valve receiver.

Abstract: 351,972. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Cioffari, B. ; 88, Washington Avenue, New Rochelle, Westchester, New York, U.S.A.) April 1, 1930, No. 10391. Convention date, April 1, 1929. [Class 40 (iii).] In television a scanning method comprises deflecting a light beam along a plurality of spaced paths and successively controlling the beams to trace a plurality of additional paths interspersed between the first spaced paths. A mirror disc 11, Fig. 2. deflects a beam of light from a source 18 along a plurality of paths in accordance with the number and tilting of the mirrors 1, 2, 3, &c. Each mirror deflects a beam across a member 10 consisting of a plurality of mirrors 12, 13, 14, &c., each inclined to its neighbours vertically as well as horizontally. As the first beam from mirror 1 passes across mirror 16 the screen 17 is scanned from d<1> to c<1>. When the beam passes across mirror 15, the screen 17 is again scanned along its breadth, but the second scanning line is spaced vertically from the first scanning line by virtue of the vertical tilt of mirror 15. Similarly the mirrors 14, 13, 12 produce scanning lines vertically spaced apart and lying between the scanning line produced by mirror 1 in conjunction with mirror 16, and that produced by mirror 2 in conjunction with mirror 16. Thus each mirror on the disc 11 results in five scanning lines on the screen, there being five mirrors on the member 10. Instead of a mirror disc 11 a lens disc 21, Fig. 5, may be employed.

Title: Television deflection power recovery circuits
IPC: H03K4/28
Filed: 1950-04-28
Abstract: 672,075. Television. RADIO CORPORATION OF AMERICA. April 28, 1950 [April 30, 1949], No. 10526/50. Class 40 (iii). [Also in Group XL (c)] Fig. 1 shows an electromagnetic scanning circuit for a cathode-ray tube 56 in which a saw-tooth voltage from a source 10 is applied via a cathode follower stage 20 to the grid of a driver stage 38 to produce a saw-tooth current flow in the deflecting coils 54, a portion of the scanning current being supplied by the damping diode 72. Capacitors 62 and 74 are charged during the period of current flow through diode 72 in such a direction that the H.T. supply from point 70 to the anode circuit of the driver stage 38 during its conductive periods is supplemented by the voltage across the capacitors. The linearity of the scan may be adjusted by variation of inductor 76 which resonates with capacitor 74 and may be adjusted to compensate for the deviation from flatness of the screen of the cathode-ray tube 56. The fly-back voltage developed across a pulse transformer 66 in the anode dircuit of valve 38 is rectified by diode 82 and smoothed to provide E.H.T. voltage for the final anode 78 of the cathode-ray tube. The stray capacitance 39 associated with the anode of valve 38 may be supplemented to lower the resonant frequency of the circuit comprising stray capacitances 39, 55, 57 and transformer winding 64 and thus improve the linearity of scan. Fig. 2 shows a modification in which the synchronizing signals from a television receiver 100 are separated in unit 104, and applied to line and frame saw-tooth generators 106, 108, respectively, H.T. supply being derived from a unit 110. The H.T. supply to the driver stage 38 from unit 110 is increased by the voltages produced across capacitors 62<SP>1</SP> and 74<SP>1</SP> as described in connection with Fig. 1. The capacitors 62<SP>1</SP>, 74<SP>1</SP> and wave shaping inductor 76<SP>1</SP> are associated with the end of the deflecting coils 54 which is at a low A.C. potential, thus obviating the necessity of filtering out the high voltage fly-back potential which is periodically present at end 58 of the coils.

Filed: 1948-04-16
Abstract: 652,114. Cathode-ray oscillographs. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 16, 1948, No. 10556. [Class 37] [Also in Groups XL (b) and XL (c)] Non-linearity of the scanning in a cathoderay tube due to eddy currents in conducting material in the field of the scanning coils is reduced by accentuating the low frequencies in the scanning wave relative to the higher frequencies. A scanning generator comprises a capacitor 1 charged from a negative potential source 4 and discharged rapidly through a diode 2 which is periodically rendered conductive by synchronizing pulses. The sawtooth wave generated is applied through a negative feed-back amplifier comprising valves 8 and 14 to the scanning coil 20. The lowfrequency component of the wave is accentuated by connecting a potentiometer 6 in series with a capacitor 5 across the input of the amplifier. Alternatively these components may be connected in the feed-back lead 22 (Fig. 2, not shown), or across the scanning coil (Fig. 3, not shown). In the latter case a resistor may be added in series with capacitor 1 to compensate for the effective resistance in shunt with the scanning coil. The desired frequency response may also be obtained by connecting an inductor in parallel with a resistor in series with the coil.
