(under subclass 226) Subject matter wherein the resistance element is disposed in a groove, slot, or recess, or in a channel shaped container.
(1) Note. The walls of the recess or groove when open on one side do not completely enclose the resistance element; and such subject matter above is not classifiable here, but in subclasses 285, 303, and 311 below. Some other structure
is necessary in addition such as a sheath on the element, or a cover on the open face of the recess or groove for classification here.
SEE OR SEARCH THIS CLASS, SUBCLASS:
161, for a mechanically variable incased resistor whose casing is partly removed to form a track for the contact.
232, for incased, embedded, or housed resistors whose casing or housing are readily openable and/or separable from the resistance element.
247, for embedded or enclosed resistors having a metallic sheath formed in separate parts, one part being recessed or channeled. 285, for a zigzag or sinuous resistor whose element extends along a groove in a base.
303, for a helical or wound resistor whose element is coiled in a groove on a core.
311, for a resistor generally whose element is mounted in a groove in a base.
