.~.~ Supports supported by opposed parts of envelope
DEFINITION
Classification: 313/274
(under subclass 271) Devices which have the filament within an envelope, the filament being supported within the envelope by means of supports (e.g., support wires, rods, or tubes), at least one of the supports being supported by a part of the envelope wall which is opposed to or spaced at a distance from the part of the envelope wall which supports either a different portion of the same support or another support.
(1) Note. This and the indented subclass does not include devices where all the supporting and/or spacing means are sealed into a common stem or press of the envelope even though the supporting and/or spacing means are widely spaced from each other.
(2) Note. Some devices in this subclass have the lead-in wires which pass through the envelope wall at the same end of the envelope so that only a single base is needed for the device.
(3) Note. One of the more common structures found in this subclass is the so-called "multiple-ended" incandescent lamp, that is, a lamp having a stem or press at each end of a substantially tubular envelope, the filament supports being supported by each of the stems or presses.

253+, for discharge devices having an envelope and support structure for a plurality of electrodes. The support structure being supported by opposed or spaced portions of the envelope. See subclass 255 where the same electrode is supported by supports which are supported at spaced or opposed portions of the envelope.
286, for other devices under subclass 238 which have an envelope and an electrode therein, the electrode being supported by means of supports (e.g., wires, rods or tubes) which are supported by opposed or spaced parts of the envelope wall.
288, and the subclasses specified in the notes to the definition of this subclass for other devices under subclass 238 which have an envelope and an electrode therein, a spacer member being positioned between the envelope wall and the electrode or an electrode support.
