Title: Improvements in and relating to Arrangement for Automatic Focusing of Projectors
IPC: G03B21/53
Filed: 1967-09-22
Abstract: 1,177,975. Slide projectors. ERNST LEITZ G.m.b.H. Sept.28, 1967 [Oct. 1, 1966], No.44158/67. Addition to 1,177, 567. Heading G2J. [Also in Division G1] As an improvement in the automatic focusing mechanism of Specification 1,177, 567, the photoelectric means and the sensing means comprise three photo-resistors FW1, FW2, FW3, positioned such that if the separation of slide and projection lens is too great for correct focus, FW1 will receive a reflection from the first surface of the transparency for glass-less slides, or of the cover glass, as the reversible motor drives the slide carrier, and will give a signal for the motor to continue driving until the reflection reaches FW2 whereupon, if no further beam is sensed by FW1, the signal from FW2 stops the motor, while if a further beam is sensed by FW1, the stop signal is over-ridden and the motor continues driving until the second beam is sensed by FW2 and the first beam by FW3, and these last two signals stop the motor. The controlling light beam reflected by the slide is two spaced mutually inclined mirrors which direct beams to FW1 and FW3, while the beam passing them reaches FW2. When glass-less transparencies "pop" due to heat this focusing mechanism restores focus, since in the absence of other signals, FW3 acts to reverse the motor. The control circuit includes AND gates TU1, TU2, TU3, TU4, and OR gates To1 as in Fig. 2, and the slide carrier is spring-biased to a starting position wherein the slide-lens distance is too great for correct focus. In a modification, a third mirror directs light to a fourth photo-resistor which senses the reflected beam from a slide inserted into the position of the previous slide and which thereupon reverses the motor.

Abstract: 986,309. Data transmission systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 22, 1963 [Dec. 26, 1962], No. 46118/63. Heading H4P. Transfer of data from one magnetic drum to another takes place in such a manner that characters read in ascending order from the transmitting drum are written in the recording drum in descending order relative to the direction of movement of the drum. The system can operate in both directions simultaneously, a drum at one location both receiving and transmitting data. Data from a unit 12, e.g. a typewriter keyboard or card reader, is recorded on drum 10 under the control of clock pulses from a clock track on the drum. The position of the first character to be transmitted is set on counter 44 by the unit 12, the counter being advanced at each revolution of the drum. When counter 42, fed by clock pulses at character rate, shows the same count as that of counter 44, the character currently being read is stored in buffer 19 and subsequently transmitted from this at slow speed over a telephone line or wireless link. At the receiver, the character is stored in buffer 21. Counter 43 indicates the position of drum 11, and counter 47 counts in reverse at each revolution of the drum. When counters 47 and 43 agree the character stored in buffer 21 is read in to the drum. Characters read in in this way will be in descending order as seen by the record head. The reading of two characters per drum cycle is mentioned.
