Abstract

A multiple-case output typewriter, tape reader punch, card reader punch, and control unit are interconnected to perform mutual transfer of complex scientific messages. The messages are coded on cards or tape and are printed in a system which provides 132 characters, three to each of 44 keys, script, subscript or superscript positioning, and color control. The exchange operates in three modes according to input, i.e., keyboard mode, card mode or tape mode.

Scientific Message Exchange

A multiple-case output typewriter, tape reader punch, card reader punch, and control unit are interconnected to perform mutual transfer of complex scientific messages. The messages are coded on cards or tape and are printed in a system which provides 132 characters, three to each of 44 keys, script, subscript or superscript positioning, and color control. The exchange operates in three modes according to input, i.e., keyboard mode, card mode or tape mode.

The keyboard produces coded electrical signals related to each key. In keyboard mode the operator manipulates the position keys and character keys. To produce the message shown in the typewriter, the CAP and A keys produce the A, the SUB, SYM and B keys produce the subscript Beta, the B key alone produces the b, and the SUP, SYM and 2 keys produce the superscript 2. The A sub Beta b squared message is printed and recorded in code on cards and tape.

The coding, which is compatible with standard 12-bit card and 6-bit tape machines, comprises:
Two bits platen position -- script, SUBscript and SUPerscript

Two bits typebasket position -- lower case, CAPital shift and SYMbol shift

One bit ribbon position -- black or red One bit carriage control or spare Six bits typeslug choice

The character cycle is thus divided into a position interval and a typeslug choice interval, each interval corresponding to a punching cycle. On tape the position bits appear as a first group of punches followed by t...
