.~.~ With mounting means for a device within envelope
DEFINITION
Classification: 174/50.54
(under subclass 50.5) Subject matter having means to mount an electrical device within the envelope.
(1) Note. This subclass provides only for hermetically sealed envelopes where the mounting means within the envelope is of general utility, that is, where the mounting structure claimed could be used for mounting any one of a number of different devices such as electrical condensers, inductances, resistors, switches, etc. The mere recitation of an electrode or electrode assembly broadly recited as the thing mounted will not exclude the device from this subclass, but if the electrode is claimed as a filament, anode, grid, cathode, or other specific electrode in the case of a lamp or electric space discharge device the device will be excluded and will be found in Class 313, Electric Lamp and Discharge Devices, subclasses 238+.
Where the supporting structure is not of general utility, but is of the type useful only in mounting the electrodes of a lamp or electric space discharge device, the patent is excluded from this class (174) and will be found in Class 313 even though the electrodes are not claimed specifically.
