Abstract: A cleaner unit is provided for applying a liquid cleaning solution onto the surface of an information disk, such as a so-called compact laser disk or the like. The cleaner unit includes a housing with a rotatable spindle (22) adapted to support the information disk in a generally horizontal orientation, in combination with a circulation system having a rotatable pump impeller (24) for spraying a jet of a cleaning solution onto the underside of the disk (12) near the spindle. A drive motor is operated by a control circuit for initially rotating the spindle and impeller in a first direction for spraying the cleaning solution against the spinning disk, with the rotational disk movement causing the cleaning solution to spread radially outwardly as a film over the underside disk surface. The cleaning solution is thrown from the disk periphery and is captured by an outer contoured deflector shroud (99) for recirculation to the pump impeller.

Abstract: A light show projector is provided for use in producing a pleasing and variable laser-like visual line pattern on a wall or the like in synchronized relation with an audio input signal such as music. The light show projector comprises a compact and portable housing having a substantially point light source projecting a narrow light beam through a rotatable color wheel having multiple radial segments of different colors, and further through an adjustable focusing lens for reflection by a dynamically supported mirror onto a wall or ceiling of a room for viewing. The mirror is resiliently supported by asymmetrically arranged support members, one of which is electromagnetically displaced in relation to selected characteristics of the audio input signal, thereby producing a multidimensional mirror displacement yielding a large and widely variant esthetically attractive laser-like line pattern.
