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.
Class 248: Supports
Devices which carry the weight of an article or articles or otherwise hold or steady it or them against the pull of gravity, and devices for holding an article to its support, which are not otherwise provided for.Subclass 346.03: Including attachment or holder for article
Class 379: Telephonic Communications
(1) Systems, processes and instruments for the two-way electrical transmission of intelligible audio information having arbitrary content over a link including an electrical conductor, between spaced apart locations, so as to enable conversation therebetween, and intended for the private use of a listener or a group of listeners. The term "intelligible" used above is intended to include the capability for transmission of speech or the like (e.g., music), rather than restriction to a specified audible signal, such as a bell or buzzer. (2) Switching, signalling or signal transmission peculiar to, or specified as for a telephone or a telephone system, except for multiplex communications as indicated in Lines With Other Classes.Subclass 110.01: COMPOSITE SUBSTATION OR TERMINAL (E.G., HAVING CALCULATOR, RADIO)

Subclass 420.01: Having loudspeaking conversation capability (e.g., hands- free type or speakerphone)
Class 292: Closure Fasteners
Bolt elements and latching devices, not combined with lock structure, for securing in closed or adjusted position any closure element, such as a door, window, gate, trunk-lid, box-cover, bag-frame, or the like.Subclass 302: Sliding catch
Class 345: Computer Graphics Processing And Selective Visual Display Systems
Processes and apparatus for selective electrical control of two or more light-generating or light-controlling display elements* in accordance with a received or stored image data signal. The image data includes character, graphical information or display attribute data. The image data may include, for example, information data from a peripheral input device, from the reception of a television signal, from the recognition of image data, or from the generation or creation of image data by a computer.
Class 348: Television
Generating, processing, transmitting or transiently displaying a sequence of images, either locally or remotely, in which the local light variations composing the images may change with time.Subclass E5.13: Disposition of sound reproducers (EPO)
Subclass E5.143: Constructional details of television projection apparatus (EPO)
