  • Cooling of pump heads in carbon dioxide chromatography systems
    Patent number: 11982474
    Abstract: The present disclosure relates to methodologies, systems and apparatus for cooling pump heads and providing balanced cooling and heat transfer between multiple pump heads. Multi-pump systems that are used to pump fluids that vary greatly in density with minor changes in temperature, such as the mobile phase of a C02-based chromatography system, require highly stable temperature conditions. In order to achieve a substantially equal average heat transfer between multiple pump heads and a coolant fluid, coolant fluid may be flowed through coolant passageways within the pump heads in a recursive and/or parallel coolant flow patterns. Such recursive and/or parallel coolant fluid flow patterns provide increased stability in temperature, compressibility, and density of the fluids passing through a multi-pump system.

  • Faucet extender
    Patent number: 11066816
    Abstract: A faucet extender having a channel adapted to extend and divert a fluid out of an open edge away from a faucet opening. The faucet extender may have a fluid outlet fitting having a receiving opening and a flow-through opening. The faucet extender may have an attachment mechanism that pivotally rotates and secures the fluid outlet fitting in an angle that diverts the fluid to the open edge. The faucet extender is adapted to interface with a variety of different faucet configurations.
