Abstract: A novel reusable flexible hand-held, mitten-shaped glove to which one or more layers of abrasive, cleaning, or polishing material may be attached to the glove's face by means of a suitable non-permanent, pressure-sensitive, and moisture-resistant adhesive that has been applied to the back of the material. The abrasive, cleaning, or polishing material may be peeled off as needed either to expose fresh material or to attach new material to the face of the glove.
Abstract: The installation comprises three units separated from one another: a grinding mill (1) fed with pieces of dry ice, a metering device (3) having an extracting spring-screw (13), and a propelling device (5) mounted in a vehicle gas conduit (4). The assembly is maintained under an atmosphere of CO.sub.2 by a cover (6). Application in the cleaning of surfaces in the nuclear industry.
