Abstract
Abstract A temperature actuated device is disclosed which is capable of movement with a change in temperature of at least a portion of the device. The device has a first member which is fabricated from a material which undergoes a relatively large change in strength over the operating temperature range of the device. This first member may be operably connected to a second spring member so that movement of the second spring member causes movement of the first member. The second spring member preferably has a different strength-temperature characteristic so that the device will attempt to assume a first stable configuration at a first temperature and a different stable configuration at a second temperature.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
169 words
A snap-action temperature actuated spring device comprising a combination of first and second spring members bearing against one another such that flexure of one such member toward its relaxed position causes flexure of the other such member away from its respective relaxed position, one of said members undergoing a substantial change in modulus in passing from a first to a second temperature within the temperature operating range of said device while the modulus of the other such member remains relatively constant such that, absent external restraint, said combination assumes a first stable configuration at one temperature within said range and another stable configuration at another; said first member having a non-linear load-deflection curve having a peak lying within the useful deflection range of said device such that in passing from one to another of those temperatures at which said stable configurations respectively obtain the flexure of said members causes deflection of said first member from one to the other side of said peak in the absence of external restraint.
Claim 2
Dependent Claim
169 words
A snap-action temperature actuated spring device comprising a combination of first and second spring members bearing against one another such that flexure of one such member toward its relaxed position causes flexure of the other such member away from its respective relaxed position, one of said members undergoing a substantial change in modulus in passing from a first to a second temperature within the temperature operating range of said device while the modulus of the other such member remains relatively constant such that, absent external restraint, said combination assumes a first stable configuration at one temperature within said range and another stable configuration at another; said first member having a non-linear load-deflection curve having a peak lying within the useful deflection range of said device such that in passing from one to another of those temperatures at which said stable configurations respectively obtain the flexure of said members causes deflection of said first member from one to the other side of said peak in the absence of external restraint.

Dependent Claim
75 words
An assembly comprising a first electrode and a spring device according to claim 2, said second member serving as a second electrode and being urged (1) into electrical contact with said first electrode by said first member at a temperature at which said first stable configuration would obtain absent the restraint of said first electrode, and (2) out of contact with said first electrode at a lower temperature at which said second stable configuration obtains.
Claim 10
Dependent Claim
174 words
An assembly comprising a temperature actuated spring device comprising a combination of first and second spring members bearing against one another such that flexure of one such member toward its relaxed position causes flexure of the other such member away from its respective relaxed position, said first member undergoing a substantial change in modulus in passing from a first to a second temperature within the temperature operating range of said device while the moduLus of said second member remains relatively constant such that, absent external restraint, said combination assumes a first stable configuration at one temperature within said range and another stable configuration at another; said assembly further comprising a first electrode and said second member serving as a second electrode which is urged (1) into electrical contact with said first electrode by said first member at a temperature at which said first stable configuration would obtain absent the restraint of said first electrode, and (2) out of contact with said first electrode at a lower temperature at which said second stable configuration obtains.
Claim 11
Dependent Claim
174 words
An assembly comprising a temperature actuated spring device comprising a combination of first and second spring members bearing against one another such that flexure of one such member toward its relaxed position causes flexure of the other such member away from its respective relaxed position, said first member undergoing a substantial change in modulus in passing from a first to a second temperature within the temperature operating range of said device while the moduLus of said second member remains relatively constant such that, absent external restraint, said combination assumes a first stable configuration at one temperature within said range and another stable configuration at another; said assembly further comprising a first electrode and said second member serving as a second electrode which is urged (1) into electrical contact with said first electrode by said first member at a temperature at which said first stable configuration would obtain absent the restraint of said first electrode, and (2) out of contact with said first electrode at a lower temperature at which said second stable configuration obtains.
