Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
174 words
A recording system comprising: a. means for generating input information representing words or parts of words, the representations being selected from a font of characters, said information being in the form of a plurality of sets of binary bits, the presence or absence of a character in said combination being represented by the state of its corresponding binary bit in said set; b. a recording medium; c. first recording means associated with said medium for recording a plurality of identical reference intervals on said recording medium, each interval having a plurality of subintervals equal to the number of binary bits in each said set, one subinterval for each one of the characters of the font, and wherein each of said subintervals defines a single binary bit, and therefore a single character, on said recording means; and d. second recording means coupled to said generating means and associated with said recording medium for recording the binary bits of said input information within the appropriate binary intervals recorded on said medium by said first recording means.
Claim 2
Dependent Claim
174 words
A recording system comprising: a. means for generating input information representing words or parts of words, the representations being selected from a font of characters, said information being in the form of a plurality of sets of binary bits, the presence or absence of a character in said combination being represented by the state of its corresponding binary bit in said set; b. a recording medium; c. first recording means associated with said medium for recording a plurality of identical reference intervals on said recording medium, each interval having a plurality of subintervals equal to the number of binary bits in each said set, one subinterval for each one of the characters of the font, and wherein each of said subintervals defines a single binary bit, and therefore a single character, on said recording means; and d. second recording means coupled to said generating means and associated with said recording medium for recording the binary bits of said input information within the appropriate binary intervals recorded on said medium by said first recording means.
Claim 3
Dependent Claim
84 words
The recorder as claimed in claim 1 wherein said recording medium is a magnetic tape having first and second parallel tracks, and said first recording means includes a first magnetic recording head in recording relation to said first track, said recorder further including means for transporting said tape past said first head in incremental lengths which define said intervals, and means coupled to said first recording head for recording clock pulses along said first track of said tape, said clock pulses defining said subintervals.
Claim 4
Dependent Claim
76 words
The recorder as claimed in claim 1 wherein said second recording means includes a second recording head for recorDing said binary bits along said second track and wherein said input means includes a plurality of binary storage elements, one for each of said characters, means for sequentially coupling said storage elements to said second recording head, means for controlling said coupling means in synchronism with said tape transport control means and said clock pulse recording means.
Claim 5
Dependent Claim
137 words
The recording system of claim 1 wherein said means for generating input information includes a shorthand machine having a keyboard comprising a set of keys wherein numerals, words or parts of words correspond to keys or combinations of keys, said machine including a set of binary switches, each switch of said set being coupled to a different key whereby the binary states of the switches in said set at each stroking of said keyboard correspond to the keys or combinations of keys which have been stroked and contain binary information designating the word or numeral information of said stroke, and further including a plurality of binary storage elements, one for each of said binary switches, and means for coupling the storage elements to said second recording means after the last key of a stroke has been released.
Claim 6
Dependent Claim
110 words
A stenographic system as claimed in claim 4 wherein said machine includes a supporting means, and said keys move relative to said supporting means, said switches comprising a plurality of cantilevered wires, each rigidly supported at one end by said supporting means and mechanically coupled at another portion to said keys, whereby said wires are displaced when said keys are depressed, a common contact bar mounted on said supporting means at a position to contact said wires when they are displaced by depressing said keys, a source of electrical energy, and electrical circuit means for completing a circuit through said source of electrical energy, said switches and said storage means.
Claim 7
Dependent Claim
46 words
A stenographic system as claimed in claim 5 wherein said keyboard further includes a numeral bar and some of said keys are used to record numerals when said numeral bar is depressed therewith, and further including a switch associated with the numeral bar and actuated thereby.
Claim 8
Dependent Claim
26 words
A stenographic system as claimed in claim 5 further including means for moving said wires relative to the contacts for said wires for purposes of adjustment.
