Claim 6

The electrical power- and heat-producing system of claim 3 wherein said temperature-responsive switching means makes contact between said two terminals thereof in response to a predetermined maximum temperature and breaks contact between said two terminals in response to a predetermined minimum temperature; whereby, with said fourth switching means being closed to operate said control means to said first condition, said temperature-responsive switching means responds to said predetermined maximum temperature to break contact between said two terminals thereof thereby removing the power from said second control coil to operate both said second switching means to disconnect said second heat-producing load from said first output of said second generator means, and said third switching means to connect said electrical load of the auTomotive vehicle to said second output of said second generator means, said temperature-responsive switching means responding to said predetermined minimum temperature to make contact between said two terminals thereof thereby delivering power to said second control coil to operate both said second switching means to reconnect said second heat-producing load to said first output and said third switching means to disconnect said electrical load of the automotive vehicle from said second output, thereby enabling said second generator means to alternately deliver power to said second heat-producing load and to said electrical load of the automotive vehicle.

Claim 7

The electrical power and heat-producing system of claim 1 further including a second heat-producing load connected to said second switching means, said second switching means connecting said second heat-producing load to said second generator means in response to said control circuit means being operated to its said first condition and said second switching means disconnecting said second heat-producing load from said second generator means in response to said control circuit means being operated to its said second condition.

Claim 8

The electrical power and heat producing system of claim 5 further including in combination, temperature-responsive switching means having a first operating condition in response to a predetermined maximum temperature and a second operating condition in response to a predetermined minimum temperature, said temperature-responsive switching means being connected to said first and second switching means so that in response to said first generator means being connected to said second generator means by said first switching means, said temperature-responsive switching means is responsive to said predetermined maximum temperature to operate said second switching means to reconnect said second generator means to the electrical load of the automotive vehicle and to disconnect said second generator means from said second heat-producing load thereby enabling said second generator means to deliver power to the electrical load of the automotive vehicle, and said temperature-responsive switching means is responsive to said predetermined minimum temperature to operate said second switching means to reconnect said electrical generator means to said second heat-producing load and to disconnect said second electrical generator means from said electrical load of the automotive vehicle thereby enabling said second generator means to deliver power to said second heat-producing load.
