Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 165: Heat Exchange

Apparatus or process not provided for in other classes for transferring heat, or apparatus or process not provided for in other classes relating to an auxiliary device particularly adapted to be used with such heat transfer apparatus.

Subclass 104.33: Cooling electrical device
Subclass 121: Mechanical gas pump
Subclass 185: HEAT TRANSMITTER

Class 257: Active Solid-State Devices (E.G., Transistors, Solid-State Diodes)

This class provides for active solid-state electronic devices, that is, electronic devices or components that are made up primarily of solid materials, usually semiconductors, which operate by the movement of charge carriers - electrons or holes - which undergo energy level changes within the material and can modify an input voltage to achieve rectification, amplification, or switching action, and are not classified elsewhere.

Subclass E23.088: Cooling by change of state, e.g., use of heat pipes (EPO)
Subclass E23.099: By flowing gases, e.g., air (EPO)

Class 361: Electricity: Electrical Systems And Devices

Systems or devices which provide safety and protection for other systems and devices; control circuits for electromagnetic devices and non-electromagnetic-type relays. Systems or devices which discharge, or prevent the accumulation of electrical charge on or in an object or material; circuits for charging objects or materials. Systems for generating or conducting an electric charge. Systems which process electrical speed signals. Circuits for reversing the polarity of an electric circuit. Systems which cause the ignition of a fuel or an explosive charge. Systems and processes for demagnetizing a magnetic field. Transformers and inductors with integral switch, capacitor or lock. Electrostatic capacitors, per se. Housings and mounting assemblies with plural diverse electrical components. Electrolytic systems and devices.

Subclass 697: With heat sink or cooling fins
Subclass 700: Change of physical state
