  • Publication number: 20160090658
    Abstract: Systems, methods, and other embodiments associated with thermal electrolytic production. According to one embodiment, a system includes a tower having an active reflux evaporator and a condenser system. The active reflux evaporator having a distributor pump assembly and an absorber. The distributor pump assembly pumps a heat pipe liquid metal to a distributor. The absorber receives the liquid metal from the distributor. The absorber facilitates evaporation of the liquid metal to form an evaporated metal. The condenser system includes a thermal load and a liquid pump assembly. The thermal load condenses the evaporated metal back to the liquid metal. The liquid pump assembly actively pumps the liquid metal to the distributor pump assembly.

  • Patent number: 7536924
    Abstract: A high frequency flexure-based dynamometer for measuring vibrations to use in determining cutting forces in a tool is disclosed. The dynamometer device may operate within a pre-selected high frequency range while measuring cutting forces less than about 1 N. The dynamometer may include two coupled flexures that interact to produce vibration modes at the edge of a selected bandwidth of interest. These modes may produce a frequency response function within the desired frequency band that has a magnified response and is substantially constant. The dynamometer may include a workpiece mounted to one of the two flexures and a one or more precision accelerometers mounted to the first or second flexures. Finite element analysis may be used to optimize the flexure design.
