Abstract

Two versions of an electromechanical buffer are shown. The buffers accept character bits in parallel and convert them to serial form. Previously stored bit of information may be retained indefinitely for re-reading purposes.

Electromechanical Buffer

Two versions of an electromechanical buffer are shown. The buffers accept character bits in parallel and convert them to serial form. Previously stored bit of information may be retained indefinitely for re-reading purposes.

In one version (upper, large drawing), a rotating disk 1 has about its periphery reeds 2 which are selectively displaced into a 0 or, 1 position for bit storing. Reeds 2 move successively through a writing station which includes air nozzles 3... 8, and electromagnet 9. Disk 1 has timing apertures 10 which are spaced apart a distance equal to the reeds corresponding in number to the bits in a single character. Light from source 11 activates photocell 12. This, in turn, conditions nozzles 3...8 to selectively displace the reeds then adjacent to the nozzles. Any displaced reeds, such as 13 and 14, are retained by electromagnet 9 while the disk 1 rotates. They are subsequently retained by barrier ring 15, as shown for a reed 16.

Reeds not displaced represent 0's, and reeds displaced represent 1's. Sensing of the stored information is performed by the photo cell 17 (small drawing).

The information may be stored indefinitely, since any displaced reeds are attracted to electromagnet 9 as they pass off the end 18 of ring 15. The reeds are restored by the reset magnet 19 before passing adjacent electromagnet 9.

The second version of the buffer (lower drawing) has a rotating disk 25 with displaceable reeds 26. Detents 27 are fo...
