Abstract
Abstract A heat generating apparatus and system for an automobile and incorporating the use of an absorption air conditioning system including temperature control means is disclosed. Heat transfer from the catalytic converter by means of a circulating heating fluid to a heating coil attached to the heat generator on the absorption system is provided as well as electrical connectons and controls for utilizing the heat energy from the catalytic converter. The use of a compressor and horsepower drain on the engine is eliminated.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
148 words
A heat generating and heat transferring apparatus utilizing waste heat from a motor vehicle catalytic converter comprising: a heat generator comprising a main tank holding heat transfer fluid and having inlet and outlet connections for said heat transfer fluid; fluid lines connected to said inlet and outlet connections transferring fluid to and from a coil associated with an apparatus which requires heat; means for controlling the temperature of said heat transfer fluid comprising a reversible electric motor mounted to said heat generator and connected to a threaded shaft projecting into a mechanical mounting means attached to said vehicle catalytic converter and thermostatic means for sensing the temperature of said heat transfer fluid and selectively activating said electric motor in a forward or reverse direction responsive to said fluid temperature and wherein said heat generator is selectively lowered into proximity and raised out of proximity with said catalytic converter.
Claim 2
Dependent Claim
148 words
A heat generating and heat transferring apparatus utilizing waste heat from a motor vehicle catalytic converter comprising: a heat generator comprising a main tank holding heat transfer fluid and having inlet and outlet connections for said heat transfer fluid; fluid lines connected to said inlet and outlet connections transferring fluid to and from a coil associated with an apparatus which requires heat; means for controlling the temperature of said heat transfer fluid comprising a reversible electric motor mounted to said heat generator and connected to a threaded shaft projecting into a mechanical mounting means attached to said vehicle catalytic converter and thermostatic means for sensing the temperature of said heat transfer fluid and selectively activating said electric motor in a forward or reverse direction responsive to said fluid temperature and wherein said heat generator is selectively lowered into proximity and raised out of proximity with said catalytic converter.
Claim 3
Dependent Claim
26 words
The heat generating and heat transferring apparatus according to claim 1 further comprising a liquid pump to transfer fluid from said coil to said heat generator.
Claim 4
Dependent Claim
38 words
The heat generating and heat transferring apparatus according to claim 1, wherein said fluid lines are of a flexible type whereby location is made simple and any possible leaks are prevented due to fluid line rupture from movement.
Claim 5
Dependent Claim
31 words
The heat generating and heat transferring apparatus of claim 1, wherein said coil is located in an insulated compartment which serves as a heat source for an absorption air conditioning system.
