Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
88 words
An apparatus for demountably mounting a device to a brittle, lightweight structure which comprises a baseplate, at least one layer of a heat-activatable thermoplastic adhesive, electrical heater means affixed to said baseplate, electrical terminals at the ends of said heater means for applying electrical current, heat-sensing means in contact with said adhesive for providing a decodeable signal, said heat-sensing means having wire leads which terminate at terminals, a socket for housing said wire lead terminals and said heater terminals, and means for attaching said device to said baseplate.
Claim 2
Independent Claim
88 words
An apparatus for demountably mounting a device to a brittle, lightweight structure which comprises a baseplate, at least one layer of a heat-activatable thermoplastic adhesive, electrical heater means affixed to said baseplate, electrical terminals at the ends of said heater means for applying electrical current, heat-sensing means in contact with said adhesive for providing a decodeable signal, said heat-sensing means having wire leads which terminate at terminals, a socket for housing said wire lead terminals and said heater terminals, and means for attaching said device to said baseplate.
Claim 3
Dependent Claim
46 words
The apparatus of claim 1 including a controller means for decoding the signal from said heat-sensing means, for controlling a temperature indicating means and for controlling the current applied to said heater means and further including plug means for operably connecting said controller to said apparatus.
Claim 4
Dependent Claim
15 words
The apparatus of claim 1 wherein said attaching means comprises at least one threaded stud.
Claim 5
Dependent Claim
