Unofficial Alpha Subclasses: R D P

DEFINITION

Classification: 8/94.1

Processes of treating hides, skins, feathers, and other animal tissues with chemicals or fluid and the resulting products not otherwise provided for.

(1) Note. This and indented subclasses also include the compositions used in the processes provided for and the resulting product unless otherwise provided for.

(2) Note. For compositions of matter including hides, skins, feathers, or animal tissues, see the appropriate composition class, particularly Class 71, Chemistry: Fertilizers,

subclass 18; Class 106, Compositions: Coating, or Plastic, subclasses 124.4+, 124.6+, 124.7, and 124.8+; Class 524, Synthetic Resins or Natural Rubbers, subclasses 9+.

(3) Note. Class 34, Drying and Gas or Vapor Contact With Solids, subclasses 280+, is the generic class for the treatment of feathers and will take all treatments of feathers not otherwise provided for. The line between Class 34, subclasses 280+ and this subclass is as follows: Class 34, subclasses 280+ takes (1) the drying of feathers, (2) nonreactive gas or vapor contact of feathers and (3) any other treatment of feathers not elsewhere provided for; this subclass takes the treatment of feathers with chemicals or fluids except (1) and (2) above. See the notes to Class 34, subclasses 280+ for feather treatments provided for elsewhere.

(4) Note. Apparatus used in carrying out the processes of this and indented subclasses are in Class 69, Leather Manufactures, subclasses 28 and 29+, unless more specifically provided for elsewhere.

SEE OR SEARCH THIS CLASS, SUBCLASS:

101+, for the bleaching of hides, skins, feathers and animal tissues.

137+, and 147+, for washing, cleaning and manipulative processes of treating furs, skins and leather with a chemical or fluid. 404+, for the dyeing of hides, hair, furs, and feathers.

27, Undertaking, appropriate subclasses, particularly

22.1+, for the treatment of dead bodies of persons for preparation for burial.

34, Drying and Gas or Vapor Contact With Solids,

280+, (see Note 3).

69, Leather Manufactures,

21, and 22 for processes of treating hides, skins, fur or leather which do not involve the use of chemicals or a fluid, and are not more specifically provided for elsewhere and for processes of fluid treatment combined with some other mechanical working or nonfluid treatment of leather.

71, Chemistry: Fertilizers,

18, (see Note 2).

106, Compositions: Coating or Plastic, appropriate subclass

and the notes thereto for compositions for coating of hides, skins, feathers, or animal tissues which form adherent fibers upon the base coated. Coating compositions which react with the hides, skins, feathers or animal tissues coated are classified in this or indented subclasses (see Note 2). 205, Electrolysis: Processes, Compositions Used Therein, and Methods of Preparing the Compostions,

692, for electrolytic treatment of hides or skins.

252, Compositions,

8.57, for compositions for treating tanned hides and skins and for treating furs.

260, Chemistry of Carbon Compounds, appropriate subclasses, for new carbon compounds and processes of preparing them, even though claimed as hide, skin, leather, feather, or animal tissue treating agents (see Note 2).

424, Drug, Bio-Affecting and Body Treating Compositions,

75, for a composition used to preserve and/or improve the appearance of a corpse for preparation for burial other than depilatories.

427, Coating Processes, appropriate subclasses, especially

323, 389, and 412, for processes of forming and adherent skin coating on a proteinaceous base. This and indented subclasses provide for treating hides, skins, feather, and animal tissue with coating type materials where the material is not used in such amounts as to produce a skin coating but only impregnates the base and the purpose of the impregnation is not to waterproof. Waterproofing by impregnation is in Class 427. Combinations of reactive fluid treatments of tanning and coating are in Class 8.

428, Stock Material or Miscellaneous Articles, appropriate subclasses, especially

6, for a treated, embellished or simulated feather or group of feathers, and subclass 473, for a plural layer product including a layer of leather, not elsewhere provided for.

434, Education, and Demonstration, 295+, for processes of preparation of biological specimens, and taxidermy and compositions used in such processes.

435, Chemistry: Molecular Biology and Microbiology,

265+, for processes of treating hides, skins, feathers and animal tissues that include fermentative action and products of such processes not otherwise provided for.

452, Butchering, for the preparation of a carcass for food, particularly

71+, for removal of hair, feathers, or fish scales and subclasses 125+ for the removal of skin.
