Special rules of classification within this subclass

This classification scheme is principally subdivided in four parts, each part having a distinct function:

  • the invention information (i.e. inventive concept and problem to be solved) as it is described in the application is classified in D07B 1/00 to D07B 9/00;
  • additional information or sub-inventions, which could be relevant for search purposes, are classified with the Indexing Codes D07B 1/00 to D07B 9/00;
  • additional information completing the invention information, for which no specific (sub-)group is foreseen in the indexing range D07B 1/00 - D07B 9/00, is classified with the Indexing Codes D07B 2201/00 to D07B 2501/00 and lower hierarchy, if applicable;
  • linked Indexing Codes D07B 2801/00 to D07B 2801/90 to specify the structural function (i.e. wire, filament, fibre or yarn; strand; core; filler etc.), to distinguish between devices and methods or to indicate general knowledge. For example, materials used in cables or ropes are classified in D07B 2205/00. The linked Indexing Code D07B 2801/10 in combination with D07B 2205/00 or lower hierarchy indicates that the specific material is used in the smallest filamentary entity of the rope or cable (i.e. wire, filament, fibre or yarn). The linked Indexing Code D07B 2801/18 indicates that the specific material is used as coating. Further details can be found in the indexing scheme relating to ropes or cables in general.

Documents not classified in the subclass D07B can be allocated the Indexing Codes D07B 1/00 to D07B 9/00 and/or D07B 2201/00 to D07B 2501/00 to identify aspects which can be used for ropes or cables.

Examples:

The invention is directed to a rope wherein a liquid lubricant is used to reduce the internal wear. In order to avoid that the liquid disappears during use, the rope is covered with a jacket. This is claimed in the independent claim. The description and dependent claims further mention that the rope comprises a wire for conducting electricity without defining special constructions. Aramid filaments are preferred as the load bearing entity. HMPE can also be used. The embodiments relate to braided ropes used for fishing nets. To be classified in D07B 1/162, D07B 1/142, D07B 1/025, D07B 1/147 , D07B 2201/1096, D07B 2205/205 linked with D07B 2801/10, D07B 2205/2014 linked with D07B 2801/10, D07B 2205/502 , D07B 2401/207 , D07B 2501/2038.

The invention is directed to an aramid rope wherein a special (i.e. regarding the chemical composition) liquid lubricant is used to reduce the internal wear. The description mentions that the rope is covered with a jacket. It is however clear from the description that the inventive concept relates to the chemical composition of the lubricant which is specially adapted for aramid ropes. To be classified in D07B 1/142 , D07B 1/025 , D07B 1/162 , D07B 2205/205 linked with D07B 2801/10, D07B 2205/50 , D07B 2205/502.

The invention is directed to a strand like tire cord having a (m+n) structure, wherein m may be 2 to 5. The outer wires of the strands are coated with an adhesion promoting agent made of a special brass composition. Moreover, it is indicated in the description that such strands may be twisted in a rope like structure to obtain an open structure. To be classified in D07B 1/062, D07B 1/0666, D07B 1/0626 , D07B 1/0613, D07B 2201/1076, D07B 2201/2011, D07B 2205/3089 linked with D07B 2801/18, D07B 2401/2095, D07B 2501/2046.

The invention is directed to a wire being coated with a special brass usable for tire cord manufacturing. No information is given to the purpose of this coating. In the embodiment the wire is used to manufacture a 3+8 strand. Alternatively to coating the wire, the entire strand may be coated. The latter is only mentioned as an obvious alternative. To be classified in D07B 1/0666, D07B 1/0626, D07B 2201/2011, D07B 2201/2043 , D07B 2205/3089 linked with D07B 2801/18, D07B 2501/2046.
