Abstract: An energy recovery apparatus for use in a refrigeration system, comprises an intake port, a nozzle, a turbine and a discharge port. The intake port is adapted to be in fluid communication with a condenser of a refrigeration system. The nozzle comprises a necked-down region and a tube portion. The nozzle is configured to expand refrigerant discharged from the condenser and increase velocity of the refrigerant as it passes through the nozzle. The turbine is positioned relative to the nozzle and configured to be driven by refrigerant discharged from the nozzle. The discharge port is downstream of the turbine and is configured to be in fluid communication with an evaporator of the refrigeration system.

Abstract: A method of manufacturing a service technician training apparatus for domestic appliance servicing comprises severing conductors within an actual appliance and connecting severed ends of the conductors to controllable switches. The training apparatus can include a plurality of the switches mounted on an instructor's console that is arranged to be obscured from view by the student that is troubleshooting the appliance.

Abstract: This invention is a methodology and apparatus for sports maneuver instruction and development comprised of a scaled miniature poseable figurine of human representation that is reversibly attached to a similarly scaled miniature of a sports implement. The figure has poseable arms legs and torso that will retain the pose set by the user until changed by the user into a different pose. The methodology for using the figure as an instructional and visual aid includes having the user holding the figure, pose and position the figure in the initial pose of a position in a sports maneuver. The user then reposes and repositions the figure as necessary to “act out” each step or a particular step the maneuver that the user was interested in. In this manner, the user, could visually teach novice sports enthusiasts, or use the figure individually to analyze known sports maneuvers or to create new ones.

Abstract: The present invention teaches a toy refrigerator with a body and a door that has an activity surface, which is either a metallic surface or a writing surface, such as a whiteboard. The body and the door is made either from plastic material or from wood. The activity surface is used as a space to teach children through use of additional play items such as magnetized alphabets or figures. The activity surface is alternatively used as writing or drawing or posting surface.
