Pneumatic Serializer Deserializer

Coded data is serialized for transmission and deserialized upon reception by a reciprocating tape valve. Minimum weight and mechanical complexity are realized.

Binary data from source 10, in the form of parallel pulses, is applied to data conduits 11 and also in reverse order to data conduits 12. Tape valve 13 includes scanning ports 14 and 15 and is reciprocal past conduits 11. The rate of tape movement is controlled by bidirectional governor 18 upon delivery of actuating fluid to driving chambers 16 and 17, respectively. Upon reciprocation of valve 13, conduits 11 and 12 are scanned to sequentially deliver pulses in them, if any, to pneumatic And' s 19 and 20. Transfer through And' s 19 and 20 is controlled by bistable jet amplifier 21. The latter's operating state is indicative of the direction of reciprocation of valve 13. Amplifier 21 is switched at the end of each reciprocation by valve port 22, cooperating with stroke limit positioned conduits 23 and 24.

Amplifier 21 also controls the reciprocation direction by controlling the supply of actuating fluid to chambers 16 and 17. New data is called for by stroke limit positioned conduits 25 and 26 to cooperate with valve opening 27 to indicate the completion of a previous cycle. Serialized data from And's 19 and 20 is transmitted to transducer 28. This closes switch 29 to transmit the data in serial form through transmission line 30. A serial pneumatic signal can be read at 31...
