DEFINITION

Classification: 234/59

(under the class definition) Device which comprises means for sensing indicia or characteristics of a pattern*, or means for sensing a specially-configured cylically effective portion of the device, and means responsive to such sensing to cause actuation of one or more tools, or to tool selection only, or to control both selection and actuation of tools.

(1) Note. Some instance of pattern control are found in preceding subclasses (e.g., as specific phases of "program control"; and as phases of "randomly actuated" control of auxiliary-operations).

(2) Note. Fig. 9 illustrates a card or sheet which bears indicia such as marks or perforations, appearing, for example, in five columns (A-E) and comprising four index points per column (in practice, the usual number of columns may be 45 or 80, with 6 to 12 index points per column). Fig. 10 illustrates a card which has been punched from the pattern of Fig. 9, without alteration of the position or the significance of any of the data. [figure] [caption]Fig. 9 A marked or punched card usuable as a pattern. (subclasses 59+) [figure] [caption]Fig. 10 A card cut from the pattern of Fig. 9. (subclasses 59+)

SEE OR SEARCH THIS CLASS, SUBCLASS:

13+, for a disclosure of a program card or tape which may resemble a pattern, but is utilized to control auxiliary-operation(s) instead of, or in addition to, tool selection.

25+, for a device wherein pattern sensors control auxiliary mechanism.
