Abstract: A torque limiting apparatus is provided having an input shaft, an output shaft, a housing, a spring, and a length adjustable shank and collar assembly. The input shaft communicates with a rotating end segment having a cam surface. The output shaft communicates with a rotating end segment having a complementary cam surface for engaging with the cam surface of the input shaft. The cam surfaces cooperate to generate separation forces between the respective rotating end segments. The housing encases the first end segment and the second end segment. The spring is supported in the housing, and is configured to oppose the separation forces generated by the cam surfaces, and is configured to urge together the first end segment and the second end segment to remain in rotating coupled engagement. The length adjustable shank and collar assembly is provided between the spring and the housing and is configured to adjust compressive force on the spring to change torque output of the apparatus. A method is also provided.

Abstract: Members formed from thermally conductive components which have a gap therebetween. The gap is bridged and the conductive components integrated into a composite member by a reinforced polymer. This provides a thermal break which inhibits the flow of heat between the conductive components of the member. This construction also blocks the transfer of sound and other vibrations between the conductive components of the member. The construction also mitigates the formation of condensation on an artifact fixed to one of the components.
