.~ Keyboard operated or pattern controlled regulator
DEFINITION
Classification: 315/292
(under subclass 291) Systems wherein the means for controlling the amount of impedance connected in the supply circuit of the load device is (1) a perforated card, sheet, or strip having the perforations arranged in a pattern so that the number and/or location of the perforations control the operation of the regulator operator means, for (2) a pattern member having a particular shape which cooperates with the regulator operating means to control the operation of the regulators, or (3) a keyboard consisting of a plurality of manually actuated keys, each of which controls the operation of the regulating means associated therewith.
