International Classification:

F03C 1/00
F28D 3/02

US Classification:

60530, 165157

Abstract:

A high efficiency shell and tube heat exchanger coupled to a hydraulic thermal engine includes an insulated cylindrical shell having first and second ends for conveying a coolant and a plurality of tubes passing through at least one of the ends for conveying a working fluid. A plurality of spaced-apart generally-transverse baffles are disposed in the shell. Each baffle is truncated along one edge defining a slot for passage of coolant along the shell inner wall and past the baffle. Successive of the baffles are rotated with respect to the longitudinal axis of the shell to cause the coolant flowing therethrough to follow a non-axial path. Multiple coolant inlets and outlets may be provided. The heat exchanger is optimized for a use wherein the second working fluid is liquid COin a supercritical fluid state. The heat exchanger tubes have an inside diameter of 0.26 inches or less.

Abstract:

A beverage flow controller includes a tube having a first end and a second end, and a length between the first end and the second end including at least three constrictions. The constrictions have a center to center spacing of at least 4. 5 times the inside diameter of the tube and have an inside diameter of 0. 6 to 0. 8 times the inside diameter of the tube. The plurality of constrictions controls the flow and provides a pressure gradient along the length of the tube.

Abstract:

A golf club handle renovating device for cleaning and for removing an outer, weather-hardened rubber surface of a golf club handle to expose an underlying supply rubber surface includes a tube containing a plurality of stiff plastic blades attached at one end to the inner surface of the tube. The blades project inwardly from the inner surface of the tube so that a second end of the blades define a longitudinal central void adapted to closely receive the handle therein.
