Abstract: Apparatus and method for thrusting a cover onto a target area from a remote location. The target area may be water containing fish or a hazardous condition such as a fire and/or a chemical spill. The apparatus comprises a housing having an open cavity, a cover within the cavity, and a pressurized gas supply for propelling the cover from the cavity and onto the target area. A guide bar positioned in the housing and a support surface attached to the cover cooperate to impart rotation to the cover as the cover is propelled from the housing. The cover may be impregnated with an agent capable of neutralizing the particular hazard, or such an agent may be injected under the cover after the cover is positioned on the affected area. In the case of a chemical spill, the cover is utilized to contain the liquid and then the liquid can be cleaned up by pumping the liquid from underneath the cover.

Abstract: A surface treating device for treating a surface having a corner formed by obstacles such as walls or curbs. The apparatus comprises a housing supported on a movable frame. An opening in the housing defines a blast zone on the surface to be treated. A hopper collects abrasive material and directs it to a propeller. The propeller propels the abrasive material from the hopper toward the blast zone with sufficient kinetic energy that the material rebounds from the surface into a rebound corridor. The rebound corridor has a first linear portion which forms the forward most aspect of the apparatus, and the first linear portion is substantially perpendicular to the surface being treated. From the rebound corridor, the recovered abrasive is returned to the hopper. The apparatus has a rotatable, adjustable handle to facilitate movement alongside and under obstacles. A push plate is provided on the rear of the frame under the handle, thereby making it easier to move the apparatus.
