Filed: 1974-06-13
Abstract: 1481213 Cameras EASTMAN KODAK CO 13 June 1974 [14 June 1973] 26263/74 Heading G2A A camera has two lenses which can be moved together so as to bring one or the other into alignment with the exposure aperture, one of the lenses having focusing means. As shown, the two lenses are a standard taking lens 22 and a telephoto lens 26, mounted in respective carriers 12, 14, the carriers sliding in respective guides 16, 18. Lens 22 is fixed focus, but lens 26 can slide axially in a tube 32 for focusing adjustment. A shutter plate 34 has an exposure aperture 38, over which lies a shutter blade 36 pivoted on a pin 40, and spring- biased into the closed position of Fig. 1. It is momentarily opened by the impact of a lever 46 actuated by the shutter release button 48. A sliding plate 54 is connected to a selector member 74 projecting through an opening in the camera wall. The member 74 is moved manually to select which lens is to be aligned with the exposure aperture. The words "standard" and "tele" are marked on the camera housing, and one or other of these is covered by a projection 94 on member 74, to indicate which lens is in position. Sliding plate 54 has a downwardly extending leg 72, and two further leg portions 58, 59. Leg 58 is attached to a snapover spring 60 above the viewfinder, and leg 59 has a slot 96 in which engages a pin 70 fixed to an adjustable element 68 of the viewfinder lens system. As shown, lens 22 is in the operative position, the word "standard" being visible. To change over to the telephoto lens, member 74 is moved to the right. Plate 54 has a bent-down portion 56 which engages in a groove in lens carrier 14, so that this also moves to the right. After is has moved a distance x, the trailing edge of a recess 51 contacts an arm 52 of carrier 12, after which the two carriers move together. Spring 60 snaps over, and carries carrier 14 into a position aligning the long focus telephoto lens with aperture 38. At the same time lens element 68 moves to alter the viewfinder field. When movement of plate 54 to the right has been completed, it uncovers a focusing member 78 which is linked with the lens mount 24, so that focusing movement of lens 26 can be effected. A blocking lug 50 on lens carrier 14 is clear of the release button 48 when either lens is aligned with aperture 38, but in intermediate positions it lies under the button and prevents it from being depressed. At the same time leg 72 appears in the viewfinder field as a visual warning.

Filed: 1930-09-05
Abstract: 368,695. Rectifying alternating current. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Sept. 5, 1930, No. 26519. Convention date, Sept. 11, 1929. Void [Published under Sect. 91 of the Acts]. [Class 38 (ii).] Vapour apparatus, arranqements of.-In a grid control system for mercury vapour rectifiers, the grid voltage is derived from two components, one alternating and bearing a fixed phase e relationship to the anode voltage and the other unidirectional, either or both being adjustable in magnitude in order that the moment at which the grid voltage reaches the critical value for ignition may be advanced or retarded. The alternating component is supplied by an auxiliary secondary winding S3 on the transformer carrying the main secondary S1 supplying the anodes b1, b2. The unidirectional component is derived through an adjustable tapping on a resistance g connected between the cathode c and the mid-point of a further secondary winding S2 supplying current to the exciter anodes d1, d2. The conductor h is thus maintained at a potential lower than the cathode c and consequently the grid potentials only rise above the cathode potential when the alternating component exceeds the unidirectional component in value, the time at which this occurs being adjustable by varying the magnitudes of the components.

Title: Colour Television Display Device
IPC: H04N9/28
Filed: 1967-06-08
Abstract: 1,193,171. Cathode-ray tube circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 8 June, 1967 [11 June, 1966; 2 Sept., 1966], No. 26519/67. Heading H4T. In a convergence correction circuit for a three-beam colour television display cathoderay tube the negative half of the field sawtooth deflection waveform, the sawtooth portion of which is symmetrical about zero potential controls convergence correction in one half of the display and a positively going pulse developed during fly-back controls the correction in the other half of the display. Thus during the negative half of the field sawtooth waveform which is supplied at terminals 20 1a 201b (Fig. 2) current flows through the R (red) G (green) and B (blue) convergence correction coils via diodes 204, 205, 216 and 217 this current being integrated by the coils to vary parabolically and so produce the required convergence in one half (the lower half) of the display. During the occurrence of the subsequent fly-back portion of the sawtooth wave the reversal of polarity of the latter cuts-off diodes 204, 205, 216, 217, the current in the convergence coils commences to decrease exponentially and the polarity across the coils reverses. Diodes 207, 231 and 239 now conduct and a positive bias voltage developed across the RC circuit 209, 211 and which exceeds the maximum value of the positive part of the sawtooth and ensures that diode 207 conducts only during the pulse portion of the fly-back is applied to both ends of coils R and G via diode 231 and resistor 233 and to one end of coil 13 via resistor 238 and diode 239. This voltage modifies the decreasing current in the coils and by adjustment of resistors 233 and 238 the convergence correction in the upper half of the display may be controlled independently of the correction in the lower half which is effected by resistors 203 and 220. For static convergence at the centre of the display, potentials developed across potentiometers 234, 236 and 251 by rectification of line fly-back pulses are utilized. In a modification, the negative part of the field sawtooth wave is fed to the convergence correction coils via a saturable inductor shunted by a resistor which operates by virtue of its inductance-current characteristic to improve the shape of the resulting parabolic current in the coils (Figs. 3 and 4, not shown).
