Abstract: 1294473 Photographic apparatus EASTMAN KODAK CO 12 Dec 1969 [12 Dec 1968] 60785/69 Heading G2A A photographic flash-light adapter 37 comprises means for receiving at least one percussion ignitable flashlamp, as shown a socket 38 for a flash-cube 28, an actuating member 51 for initiating percussion ignition of a received lamp 27, means for sequentially cocking and firing the actuating member and means for connecting the adapter 37 to a socket 15 on photographic apparatus, e.g. a camera, the socket 15 being adapted for use with electrically ignitable flashlamps. As shown, the connecting means is a mounting stem 41 which is connected in turn to the socket 38 and to the cylindrical side wall 39 of the adapter so that rotation of the camera socket 15 results in rotation of the socket 38 and of the sidewall 39. The rest of the adapter is held stationary by means of a hook 64. On actuation of the camera shutter release, thereby closing the camera synchroflash circuit, a solenoid 55 in the adapter is energized through leads 56, 57 and camera socket contacts 35, 36 to retract an armature 58, thereby freeing the actuating member 51 so that a portion 54 thereof can rise through holes 50, 48 and free an integral striker 45 in the flash-cube 28 to fire the lamp 27. The armature 58 then returns to the position shown, while the actuating member remains in its uncocked, firing, position. The member 51 is recocked as the socket 15, and hence the side wall 39, is rotated. A portion 53 of the actuating member 51 engages the edge 60 of a cut out 59 in the side wall, the edge 60 acting as a cam as the sidewall 39 is rotated. As the member 51 is depressed due to this rotation, it engages a cam surface 61 of the armature 58, which is retracted out of the path of the member 51, but which returns to the position shown under spring action to hold the member 51 in its cocked position. In another embodiment Fig. 4, (not shown), the portion 54 is replaced by a separately movable striking pin (70) having biasing means (73) urging it downwards. In a third embodiment Fig. 5, (not shown), the actuating member is a rigid member (80). Alternatively, the actuating member in any embodiment could be arranged to move into direct contact with a flash-lamp in an attached unit. When the adapter is used to receive a single lamp flash-unit, the actuating member is returned to its cocked position in response to some phase of the cyclic operation of the associated apparatus.

Title: Data transmission system
IPC: H04L12/417
Filed: 1978-07-11
Abstract: A system for the transmission of data from a number of out-station transmitters to a central receiver over a communication line or channel in which each out-station transmitter has an associated timer and a detector which "listens" to the line or channel and enables the transmitter only in the absence of detected signals from the other transmitters on the line or channel. When enabled each transmitter transmits data over the line or channel under control of its associated timer for a time interval during which the other transmitters are inhibited. The time intervals commence from the start times which differ from each other by different random delays which are short compared with the timed intervals, so that upon initial switching on of the system one of the transmitters will always commence transmission, followed by all the other transmitters in sequence. <IMAGE>
