Title: Data transmission system
Inventor: LAMPKIN JOHN OWEN JR
IPC: B66C13/48
Filed: 1968-03-13
Abstract: 1,215,555. Selective signalling. GENERAL ELECTRIC CO. 13 March, 1988 [29 March, 1967], No. 12278/68. Heading G4H. In a data transmission system, control words and a fixed binary pattern start word are entered in respective shift registers which are connected in series, shift pulses being applied to advance the words through the registers for serial transmission. Transmitter.-Commands for the speed and direction of the three crane motors are entered by manual switches into respective shift registers 30-34 and a start code is entered in registers 28, 36, the start code comprising a leading group and a transmitter identity group. The commands are shifted out serially by pulse generator 46 and gate out frequencies f 1  and f 2  in such a manner that a change in frequency occurs for each O bit and no change occurs for a 1 bit. The transmission is automatically repeated. Receiver.-In the standby condition the receiver is continuously switched between two transmission channels. As soon as a transmitter becomes active, the receiver locks on to the corresponding channel. Provided the received signal is strong enough, it passes to a signal regenerator 74 and clock extraction circuit and is shifted into registers 78-84. Detection of the start code at 86, with a cross check that it corresponds to the transmission channel to which the receiver is locked, presets a counter 88, and each time a subsequently transmitted start word is registered at 84 and the counter has reached zero after counting down the shift pulses between start codes, a transfer pulse is generated. The transfer pulse only becomes effective after several transmission cycles have been correctly received, and causes the commands stored in registers 78-82 to be gated out to the associated control circuits. A check is made that not more than one speed and direction is commanded for each motor.

Title: Metering mechanism for a photographic camera
IPC: G03B17/42
Filed: 1973-03-15
Abstract: 1421558 Metering mechanism EASTMAN KODAK CO 15 March 1973 [16 March 1972] 12450/73 Heading G2A A camera metering mechanism comprises a metering lever 18 movable between an inactive position and an active position in which it disables the transport mechanism, a film sensing member 22 movable from a retracted position to a position in which it engages a metering perforation in the film-strip 10, and a movable latch member 28 which can latch or release the metering lever, the latch member being engageable for movement by the sensing member in the same plane as that in which a spring 42' contacts the latch member urging it towards its latching position. The metering lever 18 is urged downwards by a spring 20 and in the "inactive" position of Fig. 5 (not shown) rests against a tab 30 of the latch member 28. This is carried by a post 26 secured in a support plate 14. Member 28 is biased anticlockwise by a spring 34' which has one leg 38 bearing against a fixed stud 40 and its other leg bent at 58 so as to have a portion 42' extending along a right-angled extension 32' of member 28 and engaging in a notch 56 therein. A sensing pawl 22 has a slot 24 through which post 26 extends, so that the pawl can move rotatably and horizontally. It is urged downwards by a spring 27 so that a nose 50 at its lower end rests against the film 10. As this is transported from right to left as shown, the nose 50 enters the next succeeding perforation and is consequently drawn with the film, so that pawl 22 is pivoted clockwise. The upper end of the pawl engages extension 32' and so pushes latch member 28 also clockwise, against spring 34', until tab 30 has moved clear of lever 18. Lever 18 is now pushed down by spring 20 into its "active" position, in which it disables the film transport mechanism, Fig. 6. Pawl 22 continues to pivot until a cam surface 52 at its lower end engages a fixed tab 54, which causes it to be lifted out of engagement with the film perforation. Lever 16 has meanwhile been raised as a consequence of an exposure being effected, so that tab 30 once more moves under the end of lever 18. In this arrangement the force exerted by the spring 42' on extension 32' of member 28 (fs') in Fig. 7 (not shown) is opposed to the force (F) exerted by pawl 22. Thus there is no twisting movement which would force member 28 towards plate 14, Fig. 4 (not shown), as happens in the embodiment of Figs. 1-4 (not shown), in which the spring 34' terminates at the bend portion 58. In this latter arrangement tripping the shutter may cause a loss of frictional resistance between member 28 and plate 14, with a consequent tendency for the film to move during exposure.

Abstract: 1,136,282. Digital transmission systems. COMPAGNIE FRANCAISE THOMSON HOUSTON - HOTCHKISS BRANDT. 23 March, 1966 [24 March, 1965], No. 12885/66. Heading H4P. In a digital data transmission system detection of an error in the received data causes a return error-indicating signal to be passed to the transmitter. On reception of this signal, the transmitter sends a special character repeatedly. When this is correctly received the error-indicating signal is stopped. Consequent on this cessation the transmitter sends data previously transmitted but received faulty, followed by normal traffic. In the embodiment described, under faultfree conditions parallel bit data characters are converted to serial form and transmitted. The received signals are checked for errors and passed via a first register to a second register which feeds parallel-bit data to the output. If any error is detected an error signal is returned to the transmitter, whereupon transmission of data characters is stopped and instead a special character is sent repeatedly, The error signal also enables a cyclic counter which starts stepping at character rate. If the capacity of the counter is n the number of special characters sent is a multiple of n. When a special character is recognized at the receiver the return error signal is stopped. At the transmitter this causes the cessation of transmission of special signal at the end of the current cycle of n such characters, following which n parallel-bit signals from a store, which contains data previously transmitted and received faulty, are serialized and sent to the receiver. The counter is now disabled and transmission of data characters takes place as normal.
