Abstract: Auxiliary trimmer unit for an electric dry shaver comprising a stationary and a movable cutter wherein the movable cutter is provided with spaced dual cutting surfaces. A guard unit is provided for the trimmer unit and means are provided to permit shifting of the guard alternately from a position where a first of the cutting surfaces of the trimmer is covered and a second position where the first cutting surface is exposed.

Abstract: A receiver selectively and variably tunable to one of a number of broadcast stations has an electro-optic tuning indicator for providing a visual indication of a selected station. The indicator includes a station encoder having a plurality of sets of indicia representative of a plurality of frequencies of the broadcast stations which are arranged to move past a reading station as the receiver is tuned. Positioned at the reading station is an optical reader including a light source arranged on one side of the station encoder and a fiber optic bundle having its proximal end arranged on the opposite side of the station encoder for alignment with a set of indicia. A photoelectric device forming the input to an electrical digital decoder is coupled to the distal end of the fiber optic bundle. The output of the digital decoder is coupled to a digital display.

Abstract: A radio or television receiver is selectively tunable to one of a number of carrier frequencies transmitted from distant broadcast stations and has a tuning indicator for displaying the frequency of a selected station. The indicator includes a station frequency encoder, having a plurality of sets of indicia representative of a plurality of frequencies of the broadcast stations, arranged to move, as the receiver is tuned, between a light source and the proximal end of a fiber optic bundle. The distal end of the fiber optic bundle is arranged on a display panel to illuminate segments of seven-bar numerical configuration in the form of a squared figure eight. When the receiver is tuned to a station, the indicia, corresponding to the frequency of the station, are aligned with the proximal ends of the fiber optic bundle.
