CLASS 260, CHEMISTRY OF CARBON COMPOUNDS

1	MISCELLANEOUS ORGANIC CARBON COMPOUNDS:

This subclass is indented under the class definition. Organic carbon compounds.

(1) Note. This subclass serves as the residual home for any organic carbon compounds comprehended by the Class Definition and not provided for by the integral classes delineated in the Class 260 hierarchy outline in the Lines With Other Classes section of the class definition.

665R	. C-metal:

	This subclass is indented under subclass 1. Compounds under Class 532, ... containing a metal other than a heavy metal or aluminum bonded to carbon, e.g.; 1, 4-disodium naphthalene and phenyl magnesium chloride.

665G	.. Grignard type

	This subclass has no definition.

665B	.. Beryllium containing

	This subclass has no definition.

998.11

DENTAL:

	This subclass is indented under subclass 1. Product classifiable under Class 520 ... useful in the filling of teeth or the manufacture of artificial teeth.

998.12

ABLATIVE:

	This subclass is indented under subclass 1. Product under Class 520 ... intended to be used in heat shields of the type which function by a controlled decomposition of the front surface to keep heat from the back surface. Some patents in this subclass are related to compositions useful in re-entry heat shields for space vehicles.

998.13

BRAKE, FRICTION OR ANTI-SKID:

	This subclass is indented under subclass 1. Product under Class 520 ... intended to operate by friction or rubbing as in a brake or clutch or which is intended to have a high coefficient of friction as in the prevention of skidding or slipping.

998.14

BALL, BAT, PIN OR BILLY:

	This subclass is indented under subclass 1. Product under Class 520 ... intended for use as a ball, bat, pin or billy or as any part thereof. This subclass included compositions used as e.g., solid golf balls, golf ball covers, bowling pin coating, etc.

998.15

FLOOR COVERING:

	This subclass is indented under subclass 1. Product under Class 520 ... intended to be used in preformed sheet form to cover floors or like areas exposed to pedestrian or vehicular traffic and compositions used in making the external traffic bearing surfaces of same (e.g., roll flooring, plastic tile etc.).

998.16

SOUND RECORD:

This subclass is indented under subclass 1. Products under Class 520 ... which are intended for use in making records of sound or which are used to reproduce sound (e.g., phonograph records, etc.) by other than magnetic means.

SEE OR SEARCH CLASS:

252,	Compositions, subclasses 62.51+ for compositions which record or reproduce sound by magnetic means.

998.17

PEARLESCENT:

	This subclass is indented under subclass 1. Product under Class 520 ... which has a pearlescent or opalescent appearance.

998.18

MOLD OR MOLD COATING:

	This subclass is indented under subclass 1. Product under Class 520 ... useful as a mold or in coating a mold. Many patents in this subclass are drawn to sand molds bonded with synthetic resin useful in the metal casting art.

998.19

ROAD MARKING OR PAVEMENT COMPOSITIONS (NON-CEMENTITIOUS, NON BITUMINOUS):

	This subclass is indented under subclass 1. Product under Class 520 ... which are either used as the surface exposed to vehicular traffic and applied to the surface as fluent material or are used to mark a surface used for vehicular traffic. The marking materials may be either fluent or preformed (e.g., strips, etc.).

998.2

DIPEPTIDES, E.G., ASPARTAME, ANSERINE, CARNOSINE, ETC.:

This subclass is indented under subclass 1. Compounds which are compound formed by the formation of a peptide bond between 2 amino acids.

(1) Note. The presence of the term dipeptide is not dispositive although it should alert the user to the possibility of classification in this subclass.

(2) Note. Caution should be observed in search for compounds denominated as dipeptides or containing a single peptide bond between an amino acid and another moiety or a peptide bond connecting complex heterocyclic compounds. Such compounds should be searched as if this subclass did not exist.

(3) Note. Dipeptide. Compounds denominated dipeptides have been placed in this subclass and its indents as a search aid. The patents in these subclasses have been otherwise placed as if these subclasses did not exist.

998.21

. Aspartylphenylalanone esters and cyclohexylalanine esters:

This subclass is indented under subclass 998.2. Subject matter in which the dipeptide is either a aspartylphenylaline ester or a cyclohexylalanine ester.

(1) Note. This subclass is intended to collect dipeptide sweeteners.
