Abstract
1338377 Variable resistors SMITHS INDUSTRIES Ltd 18 Dec 1970 [6 Oct 1969] 49082/69 Heading HIS [Also in Division H3] A variable electric circuit component has its value varied by means of a spindle settable to one or more fixed angular positions. In a variable resistance of this type a spindle 20 has a wiper arm attached to it inside a housing 18, the wiper engaging an annular resistive track such as a wire wound card, printed circuit board or carbon ring. The spindle is lockable in one or more fixed angular positions by means of the projection 34 which can engage one or more indentations, 45, in the outer perimeter of a plastics disc, the disc being rigidly attached to the spindle, and the indentations having been previously formed by the action of the projection 34, on the disc surface, e.g. by heating the projection 34 by an electric current. The resistance may be incorporated in an electrical tachometer such that different fixed settings of the resistor correspond to the instrument being calibrated for use with 2, 3, 4 or 6 cylinder combustion engines.
