Title: Cinematograph camera
IPC: G03B19/18
Filed: 1959-06-01
Abstract: 915,127. Kinematograph camera exposures controlling. AGFA A.G. June 1, 1959 [July 1, 1958], No. 18637/59. Class 97 (1). A kinematograph camera has coaxiallyarranged setting means for taking into account the sensitivity of the film in use and for selecting frame speed, the means for selecting the frame speed being connected to the camera housing by a friction catch and to the means for taking account of film sensitivity by a relatively weaker friction catch so that the means for taking account of film sensitivity may be adjusted without any change in the frame speed selected. Preferably the two setting means are mounted in a single constructional unit and may be of annular form surrounding a photo-cell mounted in the said unit. As shown, a photo-cell 13 is supported on a tube 12 mounted within a fixed bush 9 on the camera wall 8 and carries on its flange 14 bearings for diaphragm blades 15. Two concentric tubes 18, 19 are freely supported on the bush 9 and are connected by a weakspring friction catch 21, while tube 19 has a stronger-spring ball catch 20 connecting it to the camera wall 8 so that the tube 18 which is connected to the photo-cell diaphragm setting- ring 16 by a pin 17 may be rotated to make allowance for film sensitivity as indicated by scale 22 without rotating the tube 19 which sets the frame frequency. This setting is achieved by a pin 29 connecting the tube 19 to a further flanged bush 10 having a rear spiral face cam 11 and rotatably mounted in the bush 9, a follower pin 34 on a lever 31 causing adjustment of a plate 38 carrying brake shoes 39 which engage a disc 47 on the movable member 46 of a governor comprising leaf-springs 43 bearing weights 44 connected to a member 45 fixed on a driven shaft 37. Rotation of the film sensitivity setting tube 18 or of the frame frequency setting tube 19 adjusts the quantity of light incident on the photo-cell and hence the position of the meter needle 6 visible in the viewfinder 2, and a follow-up member for the needle causes appropriate adjustment of the diaphragm for the camera objective.

Patent GB-938710-A (GB)
Title: Photographic camera
IPC: G03B17/42
Filed: 1962-05-15
Abstract: 938,710. Photographic cameras. AGFA A.G. May 15, 1962 [May 20, 1961], No. 18726/62. Class 98 (1). A camera has electrically driven filmadvancing means, and a sprocket wheel arranged to be driven by the perforations of the moving film, said wheel incorporating a cam disc arranged to control a double exposure prevention latch, and a motor switch. In the form shown, as the film 6 is advanced by the electric motor 1, its perforations engage the teeth 7a of a sprocket wheel 7, so turning the wheel. Fixed to wheel 7 is a cam disc 8, and towards the end of a normal film advance the cam part 8a engages against a lug 9a of a lever 9, pushing it in the direction 12. Such displacement is allowed by a slot 9b in the lever sliding along a fixed pin 10, round which the lever can also pivot. A lug 9c on lever 9 engages against a part of a latch 14 pivoting about an axis 13, causing a lug 14a on the latch to engage a projection 4d of a switch member 4. This separates the switch contacts 4a, 4b, so stopping the motor 1, and closes the contacts 4b, 4c which form part of a circuit through a regulator 2 which itself can stop the motor after a complete film advance, or a faulty advance. When the shutter release 15 is pressed, a conical surface 15a thereof pivots lever 9 out of engagement with cam 8a, but at the same time maintains the latch 14 in the same position. The same motion of release 15 causes contacts 5a, 5b of another switch 5 to close, so that the regulator 2 becomes operative. Finally, the shutter is released. As the release 15 returns, the spring- loaded latch 14 enters a recess 15c in the shaft of the release. Lug 14a retracts out of contact with projection 4d, allowing contacts 4a, 4b to close once more so that the motor runs again to carry out a further film advance. As cam 8a once more engages lug 9a to push the lever along as before, the latch 14 is displaced out of the recess 15c, so allowing the release 15 to retract fully to its initial position. If the film has not been advanced by a whole frame, the lever 9 is not moved, and so latch 14 remains in the recess 15c, thus preventing any movement of release 15. In this case the motor 1 is automatically switched off by the regulator 2, to save the battery.

Title: Two-tube colour television camera
IPC: H04N9/04
Filed: 1973-04-19
Abstract: 1423783 Colour television ARVIN INDUSTRIES Inc 19 April 1973 [20 April 1972] 19140/73 Heading H4F In a colour television camera using only one camera tube to produce two chrominance signals, the object 10, Fig. 1, to be televised is split into two images, one above the other, on the camera tube face 25, by means of focusing optics 11 and 20; beam splitter 12, mirror 18 and image splitter system 22, 24. The two images rendered blue component and yellow/ red component representative respectively by filters not shown, are both raster scanned, Fig. 3, but with the beam switching from one raster to the other at the end of each line, e.g. the line sequence would be line 1 red image, line 3 blue image, line 5 red image, line 7 blue image &c. A line sequential chrominance signal is thus produced. The camera also incorporates a luminance camera tube 15, scanned in synchronism with the chrominance tube 25. The horizontal deflection voltages for the coils H1 and H2, Fig. 2 of the luminance and chrominance camera tubes 15, 25 respectively are both supplied from a 15À75 kHz output of generator 40. The vertical deflection voltage for the coil V 1  of the luminance tube 15 is taken directly from the 60 Hz output of generator 40. The line output at 15À75 kHz is used to produce a square wave at 7À875 kHz from divide by two flip-flops 46, which square wave is added to the 60 Hz frame output at adder 45 to produce the raster switching feed (Fig. 3) for the chrominance tube's vertical scan coils V 2 . The luminance amplifier 30 produces the signals Y from each line whilst chrominance amplifier 32 produces the line sequential signals R, B, R, B . . . An adder 35 fed with the chrominance signal and the inverted luminance signal (33) produces the difference signals (R-Y), (B-Y), (R-Y) . . . These are modulated on to a 90 degree phase switching sub-carrier at 3À58 MHz from generator 40 via a 90 degree phase switch 52 synchronized by the output of flipflop 46. The line sequential modulated difference signals (R-Y)<SP>1</SP> 0 , (B-Y)<SP>1</SP> 90 , (R-Y)<SP>1</SP> 0  . . . , are converted into simultaneous modulated difference signals by combining at 60 the direct signals with the one line delayed signals from delay 53. The simultaneous chrominance signal is finally combined at 65 with the luminance signal to produce an N.T.S.C. compatible composite video signal.

Title: Improvements relating to electrical protective circuits
Inventor: ANTOSZEWSKI EUGENIUSZ

Filed: 1961-06-02
Abstract: 1,011,127. Protective arrangements. ENGLISH ELECTRIC CO. L t d. May 30, 1962 [June 2, 1961], No. 19930/61. Heading H2K. An overload protective arrangement includes a timing capacitor 20 which is normally short-circuited by a transistor 12 until the output from a detector circuit 1 . . . 6 reaches a predetermined magnitude when the transistor 12 is rendered non- conducting and permits the capacitor 20 to charge from a stabilized power supply 40 ... 46. After a fixed time delay the voltage across the capacitor is sufhciont to render a transistor 30 conducting which causes a transistor 31 to conduct and energize a protective relay 38. Since the power supply is derived from a current transformer, the opening of a circuitbreaker controlled by the relay results in a loss of the power supply. Thus to permit quick resetting of the protective arrangement, a memory circuit including a capacitor 70 and diode 71 provides a supply for the transistor 12 to enable it, after a tripping operation, to conduct for a period long enough to discharge the capacitor 20. Under heavy overload conditions, current through a zener diode 58, a diode 60 and resistor 54, 55, produces a bias which renders a transistor 50 conductive, so that the resulting voltage drop across a resistor 33 renders the transistor 31 conductive without any time delay.
