Devices limited to guiding material either vertically, horizontally, or at an inclination.

Subclass 25R: Flexible wall

Class 211: Supports: Racks

Built-up open framework structures designed to support articles. Racks in the nature of upright stands or standards carrying article supports are also included, and also self-supporting articles supports, frequently built up of sheet material. The term "racks" includes frame structures and supports having flexible supporting elements, such as strands or straps, as the article-supporting elements.

Subclass 41.18: Semiconductor wafer

Class 269: Work Holders

A device which, during a work treating operation, contacts a workpiece for the purpose of (a) supporting the work against the force of gravity; or (b) preventing movement of the work in a particular direction or in all directions while, as disclosed, such work is supported against the force of gravity; or (c) providing a surface juxtaposed to the work for constraining the motion of a tool during its performance of such work treating operation. Holding articles together so that (by disclosure) a glue, cement or adhesive may set and secure said articles together is considered to be a work holding operation for this class. Thus a clamp or vise, disclosed for use by cabinet makers, carpenters, woodworkers, etc., to hold plural pieces together while an adhesive sets, is properly classifiable in this class.

Subclass 224: With yieldable means in actuation train
Subclass 296: Gapped support
Subclass 310: Support resiliently urged upwardly

Class 313: Electric Lamp And Discharge Devices

This is the generic class for electric lamp and electric space discharge device structure. Examples of such devices are electric incandescent lamps, gas or vapor filled electric discharge tubes, including lamps, mercury arc devices, vacuum discharge tubes, radio tubes, cyclotrons, cathode-ray tubes, photosensitive discharge devices, secondary emission electron multipliers, spark plugs, and open air arc and spark devices.

Subclass 506: Plural layers
Subclass 509: With dielectric layer

Class 501: Compositions: Ceramic

This is the generic class for: Glass compositions and compositions for making glass, i.e., glass batch compositions, devitrified glass-ceramic compositions and processes for producing such compositions. These compositions may be regarded as thermoplastic compositions. Refractory compositions comprising primarily earthy, inorganic materials, and/or elemental carbon. Fired clay containing compositions in the nature of porcelain, earthenware, and similar materials. These compositions may be regarded as thermosetting compositions

Subclass 102: Zirconium compound containing
Subclass 103: Zirconium oxide
Subclass 134: Titanate, zirconate, stannate, niobate, or tantalate or oxide of titanium, zirconium, tin, niobium, or tantalum containing (e.g., dielectrics, etc.)
