Abstract: In indicating devices of the invention, a slide member is disposed between two registering rectangular sheets forming a holding member and is guided for relative rectilinear movement in certain embodiments and for relative rotational movement in other embodiments, the position of the slide member relative to the holding member being adjustable according to differences in handicap and to indicate stroke holes on which strokes are to be given by one golfer to another golfer in a accordance with a particular order of handicap order numbers of a golf course. Certain embodiments are designed for use separately from a golf course score card while others include indicia to be usable as golf course score card and to more directly indicate stroke holes.

Abstract: A circuit is disclosed in which the armature and the field winding of a DC motor are respectively connected in series with first and second silicon controlled rectifiers to which controlled pulses are applied to render the rectifiers alternately conducting with a toggling action. A capacitor is connected between terminals of the rectifiers to facilitate the toggling action and a free-wheeling diode is connected in parallel with the field winding to insure that field current is flowing at the same time that armature current is flowing.
