(under subclass 1) Subject matter wherein the claimed device includes contact selecting means which in itself is acting, or automatic, the contact selecting structure operating by its own self-contained mechanism when activated by some impersonal influence as for example a signalling current or voltage transmitted from a distance, and which is not manual and requiring personal intervention; i.e., not requiring the presence of an operator. The art to be found in this and the indented subclasses is analogous to the structure to be found
in Class 335, subclasses 111+ and in Class 379, Telephonic Communications, subclasses 242+.
(1) Note. (a) The structure to be found in Class 335 is restricted to devices which are magnetically operated and of general utility and not restricted by the language in the claims to any one art device specifically classifiable elsewhere. (b) The structure to be found in Class 379 is restricted by language in the claims, other than in the preamble, which is generally recognized as restricting the device to telephony. (c) The patents classified in this and the indented subclasses are formerly in the telephone art but were found not to be restricted to the telephone art by any language other than perhaps in the preamble to the claims, and not recited as magnetically operated. A similar group of patents, not restricted to any otherwise classifiable art, but which are specifically claimed as magnetically activated are to be found in Class 335 subclasses 110+.
(2) Note. The search to be complete must be extended to the appropriate subclasses in Classes 379 and 335 as discussed, supra.
SEE OR SEARCH THIS CLASS, SUBCLASS:
1, for devices under the class definition in which a plurality of contacts are arranged to control two or more circuits and where the arrangement is not restricted to automatic selective means.
SEE OR SEARCH CLASS 335, Electricity: Magnetically Operated Switches, Magnets, and Electromagnets,
76, for electric motor controlled switches with plural contacts, subclasses 92+ for electromagnetically controlled vibrators with plural contact activating means, and subclasses 111+ for electromagnetically activated switches with plural contacts and not forming a part of a specific art device, which is otherwise classifiable, and wherein the activating structure comprises self acting (automatic) means similar to the telephone type.
340, Communications: Electrical,
825+, for remote control selective systems for controlling the operation of plural devices at a distance, the said control being exercised over a lesser number of communication lines than the number of different results which can be obtained.
379, Telephonic Communications,
242+, for automatic telephone systems limited to instrument and their combinations for effecting the transmission of spoken sounds by means of electricity and in which connection
between subscribers are automatically and mechanically made at a central station, without the aid or presence of an operator.
