Abstract: This device combines a carbide steel blade, a guide scraper post, and a cleaning pad saturated with solution to clean and condition a magnetic tape cassette. The cleaning pad is a member of a disposable pad strip containing a plurality of individual cleaning pads such that a fresh cleaning pad may be used for each cleaning application. A rotary dispensing valve delivers a predetermined amount of cleaning solution to the individual pad at the commencement of each cleaning cycle. Operation of the cleaning machine is initiated by depressing a starting lever which indexes the pad strip and dispenses cleaning solution from the rotary valve to the cleaning pad, while moving the scraping blade and cleaning pad into a position to contact the tape. Pushing of a run button then starts the tape drive system.

Abstract: Methods and apparatus for removing particles from sheet materials, particularly plastic materials that are to be laminated to other materials, are disclosed. The sheet is destaticized, wiped and lightly scraped to dislodge particles from the sheet. The dislodged particles are removed from the sheet by suction. Scrapers with single fixed blades and scrapers with multiple movable blades are used to dislodge particles that are embedded in or adhered to the sheet. The process and apparatus are particularly useful for cleaning sheets of plastic material that are used in laminated glazings having stringent optical requirements.

Abstract: An apparatus for loosening-up the walked-down nap of a carpet has a carrier that rides on rollers on the carpet and which is provided with a pair of brushes spaced apart in the displacement direction. Each brush has an elastic bed for a multiplicity of wire bristles with bent-over ends that engage in and loosen up the carpet nap. The brushes may be cylindrical and driven by a motor on the carrier which also drives the rollers. The trailing brush engages more deeply in the carpet nap than the leading brush.

Abstract: An apparatus and a method of cleaning and polishing capsules in which the capsules are blown against one side of an electrically charged screen to clean dust therefrom by their impacting on the screen. Air is drawn through the screen from the other side of the screen to draw off the dust through the screen. The capsules drop down from the screen and are delivered to a rotating inclined drum having a lining of napped fabric wherein the capsules are tumbled for residual cleaning and polishing.

The preferred design includes a reversible drive for the polishing wheel, a brake for restraining movement of the apparatus along the floor, a pair of oppositely rotated polishing heads on the portable polishing unit, a hydraulic drive for the polishing heads, and an electric power supply including ring and brush contacts permitting free movement of the apparatus around the automobile.

Abstract: An electric stippling device includes a housing within which is positioned an electric motor, a rotatable eraser member operably connected to the motor for rotation therewith and a stippling shaft member operably connected to an opposite end of the motor for reciprocatory movement.

Abstract: An electrically driven hand-held apparatus, for applying a treating material, such as wax, to a surface and for subsequently buffing up the surface or working the treating material thereinto, has a central applicator element surrounded by an annular buffing or brushing element, these elements being relatively displaceable axially so as to present one or the other in a projecting working position. The elements are rotatable by a bi-directional motor, and are coupled by an arrangement which ensures that reversing the direction of rotation automatically causes the relative axial displacement of the two elements. The applicator element may have a reservoir for the treating product, and a spring-loaded feed piston therein. The reservoir may have a valved inlet, and a stem may be inserted for filling the reservoir from an aerosol can. The applicator element and the buffing or brushing element may be removable and replaceable as an assembly.

Abstract: Coatings are loosened for removal from various substrates by rotating a chain-like flail against the coating while maintaining the flail oriented and positioned with respect to the surface of the coating so that the next-to-last terminal link of the flail barely strikes the coating on the edge of the link, twists and then whips the terminal link flat against the coating on the side of the link. The flail is useful for remote controlled operations as underwater or in a hazardous area as high radiation environment and may be employed for cleaning any underwater surface such as conduits, ships hulls, docks, and offshore drilling or production structures. In particular, the flail works well on underwater conduits when used in combination with a wire wheel brush which removes the coating from the conduit after the coating is first loosened by the flail.

Abstract: A car wash apparatus having inner and outer, counterrotating curtain assemblies of circular configuration. Each curtain comprises strip elements which at rest are suspended in close proximity to those strip elements of the other curtain. The strips are displaced during travel over the car body resulting in the strips from one curtain intermingling with strips of the other curtain to enhance the strips cleaning action. A drive mechanism powers the curtains through concentric drive shafts with a water supply shown provided through same. Curtain confining means are supported adjacent the curtain paths guiding the curtain strips for rotational travel into desired impingement against the vehicle body. The strip elements may include highly flexible fibrous segments to clean irregular surface areas of the vehicle. Rotary brushes within the inner curtain assembly clean the vehicle sides. Said brushes are powered via a continuous cable carried by said curtain assembly reeved through power take-off pulleys.
