Abstract
Abstract The use of an automatic dial-signal generating means is shared by a plurality of stations each having its own telephone line. Each station has a plurality of selective controls each operable to select a respective one of a number of programming devices common to all the stations, and means which mark that station in response to a selection-control operation thereat. Appropriate means preclude a more-than-transient coexistent marking of any plurality of the stations, and there is associated with each station a respective means responsive to a selection-control operation at that station for supplying activating current therefrom to the selected programming device only after that station has remained marked for a brief but more-than-transient period.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
149 words
In a multi-station telephone dialing system which includes dial-signal generating means and a plurality of common programming devices by the supply of activating current to any of which the generating means is programmed for a respective telephone address: (A) a plurality of stations each having (i) a respective telephone line, (ii) a plurality of selection controls each connected with and operable to select a respective one of said programming devices, and (iii) means normally effective to mark that station in response to a selection-control operation thereat; (B) means connected with said stations for precluding a more-than-transient coexistent marking of any plurality thereof; and (C) a plurality of means, each associated with a respective station and responsive to a selection-control operation thereat, each for supplying activating current from the respective station to the programming device selected thereat only after that station has remained marked for a brief but more-than-transient period.
Claim 2
Dependent Claim
149 words
In a multi-station telephone dialing system which includes dial-signal generating means and a plurality of common programming devices by the supply of activating current to any of which the generating means is programmed for a respective telephone address: (A) a plurality of stations each having (i) a respective telephone line, (ii) a plurality of selection controls each connected with and operable to select a respective one of said programming devices, and (iii) means normally effective to mark that station in response to a selection-control operation thereat; (B) means connected with said stations for precluding a more-than-transient coexistent marking of any plurality thereof; and (C) a plurality of means, each associated with a respective station and responsive to a selection-control operation thereat, each for supplying activating current from the respective station to the programming device selected thereat only after that station has remained marked for a brief but more-than-transient period.
Claim 3
Dependent Claim
37 words
The subject matter claimed in claim 1 further including means effective upon the supply of activating current to the selected programming device to place said generating means in operation on the telephone line of the marked station.
Claim 4
Dependent Claim
27 words
The subject matter claimed in claim 2 further including means, rendered effective upon the conclusion of said operation of said generating means, for de-marking the marked station.
Claim 5
Dependent Claim
55 words
The subject matter claimed in claim 2 further including means, responsive to the marking of any of said stations and effective upon the ensuing passage of a time appreciably longer than that required for the dialing of any of said telephone addresses without said generating means having operated to conclusion, for de-marking the marked station.
Claim 6
Dependent Claim
56 words
The subject matter claimed in claim 2 further including for each station a respective means rendered effective as an incident to the placing of said generating means in operation on the telephone line of that station for precluding a re-marking of that station until the expiration of an appreciable interval after the conclusion of such operation.
Claim 7
Dependent Claim
50 words
The subject matter claimed in claim 1 wherein said marking means of each station comprises a respective station relay and a holding means therefor, and wherein said means for precluding a more-than-transient coexistent marking of any plurality of said stations includes circuit means connected with the several said holding means.
Claim 8
Dependent Claim
57 words
The subject matter claimed in claim 6 wherein said circuit means comprises a series circuit interconnecting said stations in a predetermined order of priority and effective while any one of said stations other than that of lowest priority remains marked for incapacitating the holding means of all of said stations lower in priority than said one station.
Claim 9
Dependent Claim
144 words
In a multi-station telephone dialing system including dial-signal generating means: (A) a plurality of stations each having (i) call-initiating control means, (ii) a respective telephone line and (iii) means responsive to operation of said control means for effecting a temporary seizure of said generating means by that station and the placement of said generating means in operation on that line for the dialing of a predetermined telephone address; (B) means precluding the simultaneous seizure of said generating means by any plurality of said stations; and (C) a plurality of means, each associated with a respective station and rendered effective as an incident to any given seizure of said generating means thereby but otherwise independent of that station''s control meaNs, for precluding a re-seizure of said generating means by that station until the expiration of an appreciable interval after the termination of said given seizure.
Claim 10
Dependent Claim
144 words
In a multi-station telephone dialing system including dial-signal generating means: (A) a plurality of stations each having (i) call-initiating control means, (ii) a respective telephone line and (iii) means responsive to operation of said control means for effecting a temporary seizure of said generating means by that station and the placement of said generating means in operation on that line for the dialing of a predetermined telephone address; (B) means precluding the simultaneous seizure of said generating means by any plurality of said stations; and (C) a plurality of means, each associated with a respective station and rendered effective as an incident to any given seizure of said generating means thereby but otherwise independent of that station''s control meaNs, for precluding a re-seizure of said generating means by that station until the expiration of an appreciable interval after the termination of said given seizure.
Claim 11
Dependent Claim
36 words
The subject matter claimed in claim 8 wherein said means precluding the simultaneous seizure of said generating means by any plurality of said stations includes circuit means interconnecting said stations in a predetermined order of priority.
