Abstract
Abstract A circuit for converting a single coded input character into a plurality of coded output characters by applying a portion of the coded input character to a character generator device and deriving the remaining inputs to the character generator device from a counter which is incremented each time an output character is generated. The multiple character sequence is terminated when a predetermined output is obtained from the character generator.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
129 words
A circuit for converting a single coded input character into a plurality of coded output characters comprising: character generator means adapted to generate a predetermined coded output character in response to the application thereto of a selected combination of input bits; means for applying at least a portion of an input character as input bits to said character generator means; counter means; means for applying the output from said counter means as the remaining input bits to said character generator means; means operative only at times when an output character is be generated by said character generator means for altering the output from said counter means; and means responsive to a predetermined output from said character generator means for terminating the generating of characters by said character generator means.
Claim 2
Dependent Claim
129 words
A circuit for converting a single coded input character into a plurality of coded output characters comprising: character generator means adapted to generate a predetermined coded output character in response to the application thereto of a selected combination of input bits; means for applying at least a portion of an input character as input bits to said character generator means; counter means; means for applying the output from said counter means as the remaining input bits to said character generator means; means operative only at times when an output character is be generated by said character generator means for altering the output from said counter means; and means responsive to a predetermined output from said character generator means for terminating the generating of characters by said character generator means.
Claim 3
Dependent Claim
25 words
A circuit of the type described in claim 1 wherein the count in said counter means is incremented each time an output character is generated.
Claim 4
Dependent Claim
58 words
A circuit of the type described in claim 2 wherein there are a plurality of said counter means, wherein the count in a first of said counter means is incremented each time an output character is generated; and wherein the counts in said remaining counter means are incremented each time an overflow occurs from the preceding counter means.
Claim 5
Dependent Claim
26 words
A circuit of the type described in claim 1 wherein said coded input character is derived from the depression of a single key on a keyboard.
Claim 6
Dependent Claim
73 words
A circuit of the type described in claim 1 including means for indicating that an input character may represent a plurality of output characters; a character storage means; means for normally passing input characters directly to said character storage means; and means responsive to an output from said indicating means for applying an input character to said converting circuit and for applying the output from said converting circuit to said character storage means.
Claim 7
Dependent Claim
40 words
A circuit of the type described in claim 5 wherein said input characters are coded in ASCII; and wherein said indicating means is energized when a character in a selected stick of said ASCII code is applied to said circuit.
Claim 8
Dependent Claim
51 words
A circuit of the type described in claim 1 wherein said character generator means does not have a coded output which corresponds to the coded input applied to said character generator after the last character of a desired sequence has been generated whereby said predetermined output is an all zeros code.
Claim 9
Dependent Claim
73 words
A circuit of the type described in claim 1 including a plurality of different sources for said coded input characters; a separate counter means for each of said sources; means for indicating the input character source which is to have access to said character generator at any given time; and means responsive to said indicating means for gating the outputs from the indicated source and its corresponding counter means to said character generator.
Claim 10
Dependent Claim
86 words
A circuit of the type described in claim 1 wherein said character generator is in two parts; wherein said counter means is in two parts; wherein the first part of said character generator accepts the portion of the input character and the output from one of said counter means and generates as an output an intermediate code; and wherein the second of said character generator means accepts said intermediate code and the output from the other said counter means to generate the desired coded output character.
Claim 11
Dependent Claim
43 words
A circuit of the type described in claim 9 wherein said second counter is a stroke substitute counter which is incremented After each character is generated and wherein said first counter means is incremented when an overflow occurs from said stroke substitute counter.
