Abstract:
1. A nozzle heater-cooler assembly, comprising: a) a hollow cylindrically shaped cartridge that contains an electrical element that contacts flat against the bottom surface of a housing; b) a spring biasing said cylindrically shaped cartridge to lower as measured from base of said nozzle hub to enable a change in position of said electrical element; c) a second larger diameter cylindrically shaped body that said cylindrically shaped cartridge and said spring are fit surrounds the cartridge and spring; d) a central opening means for allowing said heater cooler assembly to slide on body of said nozzle and moveable from an unlocked position with main slide retracted from said nozzle with a groove to a locked position with said main slide extending into said nozzle with a groove; e) an electrical path through metallic rods and springs to enable conductors to fit in a small space and allow movement by translation of the electrical path along one axis a series of dissimilar metal rods with a common heat conduction pad that enables electrical connection of all said dissimilar metal rods; f) a convective cooler design for said nozzle that simultaneously directs pressurized gas along each face of a hexagonally shaped hub; g) a resistive element design composed of two elements on parallel planes, electrically connected in a series circuit.
