DEFINITION

Classification: 34/201

(under the class definition) Apparatus including an enclosure which may be open on one side (including the top side).

(1) Note. See this class, apparatus subclass 92 and notes, for vacuum drying.

(2) Note. For other enclosures which are or may be used for treating material, see classes in the search notes below referencing this (2) Note.

SEE OR SEARCH THIS CLASS, SUBCLASS:

88, for enclosures with display, inspecting or illuminating means, and see notes.

192+, for removable shelf or tray type. 237, and 238, for floors or trays on which material is piled but having no means other than a mere surrounding flange to enclose the same. Such devices are not in this group unless combined with additional means such as covers or walls to enclose the material.

242, for material entrance seals including enough house, kiln or container structure to cooperate with a seal, including those seals in the form of a material transfer chamber.
