Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
181 words
A repertory dialer comprising: a plurality of mechanically alterable digit selector switches arranged in groups, each group representing a stored telephone number, and each selector switch representing one digit of a stored number; counting means including a ring counter operative to provide at its output a plurality of time sequential signals; gating means operative to connect a selected group of digit selector switches to the output of said counting means thereby to sequentially energize the digit selector switches in said selected group to provide a series of signals representing a predetermined number; a number generator operative to convert the series of signals from said selected group of digit selector switches to a form adapted to call the predetermined number; and said gating means including: a plurality of AND gates each connecting each one of said digit selector switches to respective outputs of said ring counter; and a plurality of manually actuable number selector switches, each connected to selected ones of said AND gates and operative to couple said sequential sequence of output signals to a selected group of digit selector switches.
Claim 2
Dependent Claim
181 words
A repertory dialer comprising: a plurality of mechanically alterable digit selector switches arranged in groups, each group representing a stored telephone number, and each selector switch representing one digit of a stored number; counting means including a ring counter operative to provide at its output a plurality of time sequential signals; gating means operative to connect a selected group of digit selector switches to the output of said counting means thereby to sequentially energize the digit selector switches in said selected group to provide a series of signals representing a predetermined number; a number generator operative to convert the series of signals from said selected group of digit selector switches to a form adapted to call the predetermined number; and said gating means including: a plurality of AND gates each connecting each one of said digit selector switches to respective outputs of said ring counter; and a plurality of manually actuable number selector switches, each connected to selected ones of said AND gates and operative to couple said sequential sequence of output signals to a selected group of digit selector switches.
Claim 3
Dependent Claim
106 words
A repertory dialer according to claim 1 wherein said number generator includes: a binary counter; a plurality of counter preset gates each connecting a respective one of the digits of said digit switches to said counter and each operative to preset said counter to a binary number representative of the corresponding digit of said digit switches; clock means for generating 60/40 telephone pulses corresponding to the numbers preset in said counter thereby to provide telephone dialing pulses adapted to be transmitted over a telephone line; and means coupled to said binary counter and said ring counter for providing a predetermined interdigital time delay between telephone pulses.
Claim 4
Dependent Claim
156 words
A repertory dialer comprising: a plurality of mechanically alterable digit selector switches arranged in groups, each group representing a stored telephone number, and each selector switch representing one digit of a stored number; counting means operative to provide at its output a plurality of time sequential signals; gating means operative to connect a selected group of digit selector switches to the output of said counting means thereby to sequentially energize the digit selector switches in said selected group to provide a series of signals representing a predetermined number; a number generator operative to convert the series of signals from said selected group of digit selector switches to a form adapted to call the predetermined number; and muting means connected between one of said digit selector switches and said counting means and operative to stop the operation of said counting means when said one of said digit selector switches is energized and set to a predetermined position.
Claim 5
Dependent Claim
156 words
A repertory dialer comprising: a plurality of mechanically alterable digit selector switches arranged in groups, each group representing a stored telephone number, and each selector switch representing one digit of a stored number; counting means operative to provide at its output a plurality of time sequential signals; gating means operative to connect a selected group of digit selector switches to the output of said counting means thereby to sequentially energize the digit selector switches in said selected group to provide a series of signals representing a predetermined number; a number generator operative to convert the series of signals from said selected group of digit selector switches to a form adapted to call the predetermined number; and muting means connected between one of said digit selector switches and said counting means and operative to stop the operation of said counting means when said one of said digit selector switches is energized and set to a predetermined position.
Claim 6
Dependent Claim
23 words
A repertory dialer according to claim 3 wherein said muting means includes a manually operable switch for restarting operation of said counting means.
Claim 7
Dependent Claim
37 words
A repertory dialer according to claim 1 wherein said number generator includes a multitone oscillator and an input matrix and is operative to generate selected dual-frequency signals in response to signals from said selected group of switches.
Claim 8
Dependent Claim
37 words
A repertory dialer according to claim 1 wherein said number generator includes pulse generation circuitry operative in response to signals from said selected group of switches to produce telephone system compatible pulses to call the predetermined number.
Claim 9
Dependent Claim
42 words
A Repertory dialer according to claim 1 wherein said counting means includes clock means coupled to said ring counter and to said gating means and operative in response to actuation of a number selector switch to control operation of said ring counter.
Claim 10
Dependent Claim
51 words
A repertory dialer according to claim 1 wherein each of said digit selector switches comprises a multiposition switch having a moveable contact and a plurality of stationary contacts, said moveable contact being connected to a respective one of said AND gates, and said stationary contacts being connected to said number generator.
Claim 11
Dependent Claim
26 words
A repertory dialer according to claim 1 wherein each group of digit selector switches is disposed in a respective module removably contained within a common housing.
Claim 12
Dependent Claim
31 words
A repertory dialer according to claim 8 wherein a group of multiposition switches representing a stored number are housed in a circuit board which contains etched connections to the associated circuitry.
Claim 13
Dependent Claim
47 words
A repertory dialer according to claim 10 wherein each of said multiposition switches is a rotary switch having a rotor disposed for rotation within said circuit board, said movable contact being attached to said rotor and adapted to selectively contact said stationary contacts on said circuit board.
