Claim 2

A telephone communication control system for use in controlling the operation of apparatus by monitoring the progress of said apparatus between a first and a second site, comprising in combination, (a) a first series path including a first and second telephone handset arranged in a series circuit between said first and second sites to provide a talk/receive path therebetween, said series path including control means operative in a first mode to supply a first control signal when said series path is complete and operative in a second mode to provide a second control signal when said series path is opened manifesting an interruption of said talk/receive path, (b) means responsive to said first control signal for applying an operating level to said monitored apparatus to enable operation of the same, and responsive to said second control signal for disabling operation of said apparatus when said series path is opened, (c) switching means associated with at least one of said handsets to enable a user to selectively open or close said series path.

Claim 3

The telephone communication control system according to claim 1 wherein said switching means comprises at least one normally closed switch located on one of said telephone handsets and arranged in said series circuit, whereby operation of said switch by a user opens said series circuit to cause said control means to provide said second control signal, whereby said operation of said apparatus is disabled.

Claim 4

The telephone communication control system according to claim 1 wherein said control means includes a relay coil in series with said series path and having a first normally opened contact indicative of said second control signal, said coil when energized due to said completed series path, operative to close said contact indicative of said first control signal.

Claim 5

A telephone communication control system for use in selectively supplying operating potential to a controlled apparatus by monitoring the progress of said apparatus between a first and a second control site, comprising in combination: (a) a connector adapted to be coupled to a source of operating potential by means of a first and second path, (b) first and second telephone handsets arranged in a series circuit between said first and second sites to provide a receive/talk path therebetween, said series circuit including control means operative to provide a first control signal when said series circuit is complete and a second control signal when said series path is opened, (c) means coupled in series with one of said first and second paths and responsive to said first control signal to close said path to supply said operating potential to said connector in a first mode and responsive to said second control signal to open said path in a second mode indicative of said series path being opened and hence, to remove operating potential from said connector during said control signal, and (d) switching means associated with at least one of said handsets to enable a user to selectively open or close said series circuit, whereby said path is opened when said series circuit is opened due to the activation of said switching means or another opening of said series path.

Claim 6

A telephone communication control system for use in selectively supplying operating potential to a controlled apparatus by monitoring the progress of said apparatus between a first and a second control site, comprising in combination: (a) a connector adapted to be coupled to a source of operating potential by means of a first and second path, (b) first and second telephone handsets arranged in a series circuit between said first and second sites to provide a receive/talk path therebetween, said series circuit including control means operative to provide a first control signal when said series circuit is complete and a second control signal when said series path is opened, (c) means coupled in series with one of said first and second paths and responsive to said first control signal to close said path to supply said operating potential to said connector in a first mode and responsive to said second control signal to open said path in a second mode indicative of said series path being opened and hence, to remove operating potential from said connector during said control signal, and (d) switching means associated with at least one of said handsets to enable a user to selectively open or close said series circuit, whereby said path is opened when said series circuit is opened due to the activation of said switching means or another opening of said series path.

Claim 7

The telephone communication control system according to claim 4 wherein said series circuit is adapted to be coupled to a source of biasing potential for supplying a current flow through said series path, with said control means responsive to said current flow to provide said first control signal during the presence of said current and to provide said second control signal during the absence of said current due to an opening of said series path.

Claim 8

The telephone communication control system according to claim 5 further including: a momentary switch coupled to said means responsive to said control signal for operating said means in said first mode during the presence of said first control signal.

Claim 9

The telephone communication control system according to claim 4 further including: first indicating means responsive to said first control signal to provide a first indication when operating potential is being supplied to said connector.

Claim 10

The telephone communication control system according to claim 4 further including: second indicating means responsive to said control signal to provide a second indication when operating potential is removed from said connector.

Claim 11

A telephone communication control system for selectively supplying operating potential to a controlled apparatus by monitoring the progress of said apparatus at first and second remote sites, comprising in combination: (a) an output connector adapted to be coupled to a source of operating potential by means of a first and second path and adapted to couple to said controlled apparatus for supplying operating potential thereto, (b) a series circuit including first and second telephone handsets each associated with one of said sites, said series circuit including control means arranged in said circuit and operative to energize when said circuit is complete indicative of an effective talk/receive path between said sites, (c) control switching means coupled in series with one of said output connector paths and operative to close said path in a first mode indicative of an effective talk/receive path and to open said in a second mode, (d) means coupled to said control switching means and responsive to said control means being operative to operate said switching means in said first mode to supply operating potential to said connector, to operate said control switching means in said second mode and to remove operating potential from said connector when said series circuit is opened, and (e) at least one normally closed switch in series with and located at one of said handsets to enable a user to selectively open said series circuit to thereby selectively remove operating potential from said connector.

Claim 12

A telephone communication control system for selectively supplying operating potential to a controlled apparatus by monitoring the progress of said apparatus at first and second remote sites, comprising in combination: (a) an output connector adapted to be coupled to a source of operating potential by means of a first and second path and adapted to couple to said controlled apparatus for supplying operating potential thereto, (b) a series circuit including first and second telephone handsets each associated with one of said sites, said series circuit including control means arranged in said circuit and operative to energize when said circuit is complete indicative of an effective talk/receive path between said sites, (c) control switching means coupled in series with one of said output connector paths and operative to close said path in a first mode indicative of an effective talk/receive path and to open said in a second mode, (d) means coupled to said control switching means and responsive to said control means being operative to operate said switching means in said first mode to supply operating potential to said connector, to operate said control switching means in said second mode and to remove operating potential from said connector when said series circuit is opened, and (e) at least one normally closed switch in series with and located at one of said handsets to enable a user to selectively open said series circuit to thereby selectively remove operating potential from said connector.
