B 23 Q

DETAILS, COMPONENTS, OR ACCESSORIES FOR MACHINE TOOLS, e.g. ARRANGEMENTS FOR COPYING OR CONTROLLING (tools of the kind used in lathes or boring machines B 23 B 27/00); MACHINE TOOLS IN GENERAL, CHARACTERISED BY THE CONSTRUCTION OF PARTICULAR DETAILS OR COMPONENTS; COMBINATIONS OR ASSOCIATIONS OF METAL-WORKING MACHINES, NOT DIRECTED TO A PARTICULAR RESULT

Notes

(1)

In this subclass, groups designating parts of machine tools cover machine tools characterised by constructional features of such parts.

(2)

In this subclass, the following terms or expressions are used with the meanings indicated:

–

"controlling" means influencing a variable in any way, e.g. changing its direction or its value (including changing it to or from zero), maintaining it constant, limiting its range of variation; [3]

–

"regulation" means maintaining a variable automatically at a desired value or within a desired range of values. The desired value or range may be fixed, or manually varied, or may vary with time according to a predetermined "programme" or according to variation of another variable. Regulation is a form of control; [3]

–

"automatic control" is often used in the art as a synonym for regulation. [3]

Attention is drawn to the Notes following the title of class B 23.

Notes

(1)

In groups B 23 Q 1/44 to B 23 Q 1/62, the following expressions are used with the meaning indicated: [6]

–

"sliding pair" means a pair consisting of two elements operating in such a way that only straight line movement between both elements is possible; [6]

–

"rotating pair" means a pair consisting of two elements operating in such a way that only rotary movement between both elements is possible; [6]

–

"screw pair" means a pair consisting of two elements operating in such a way as to produce simultaneous rotation and axial translation between both elements. [6]

(2)

In groups B 23 Q 1/44 to B 23 Q 1/62, where more than one pair of elements is provided on the same axis for the same kind of movement, the pairs are regarded as a single pair for the purposes of classification. [6]
