DEFINITION
Classification: 451/559
MISCELLANEOUS:
(under the class definition) Invention not strictly falling under any other subclass in this class either because of some inherent abrading distinction or because it is involving an operation which in itself or in combination is only doubtfully classifiable as an abrading operation or because the operation involved is merely cognate or accessory to some abrading operation without being sufficiently distinct to warrant assignment to another art.
CROSS-REFERENCE ART COLLECTIONS
The following subclasses are collections of published disclosures pertaining to various specified aspects of the abrading art. These specified aspects do not form appropriate bases for subclasses in the foregoing classification (i.e., subclasses superior hereto in the schedule) wherein original copies of patents are placed on the basis of proximate function of the apparatus. These subclasses assist a search based on remote function of the apparatus and may be of further assistance to the searcher, either as a starting point in searching this class or as an indication of further related fields of search inside or outside the class. Thus, there is here provided a second access for retrieval of a limited number of types of disclosures.
(1) Note. Disclosures are placed in these subclasses for their value as references and as leads to appropriate main or secondary fields of search, without regard to their original classification or their claimed subject matter.
(2) Note. The disclosures found in the following subclasses are examples, only, of the indicated subject matter, and in no instance do they represent the entire extent of the prior art.
