  • Patent number: 4132039
    Abstract: A lightweight hand operated abrasive blasting apparatus operatively connected with a remote station arranged to provide an air stream with a particulate abrasive material, and an air suction, the apparatus having a housing with an open side facing a work surface that is to be blasted. The abrasive, such as steel grit, is carried to the center of an impeller wheel which centrifugally projects the abrasive in the form of a transversely elongated stream against the work surface, and a vacuum line connected with the housing draws the spent abrasive particles along with particles of material removed from the surface and delivers the material to the remote station for separation and reclaiming of the abrasive particles.

  • Patent number: 4045915
    Abstract: A manually portable casing equipped with suitable handle means has an outer end opening and a sandblasting hood mounted in the casing has a corresponding outer end opening which fits into the outer end opening of the casing. A rotary blaster nozzle inside the hood is supplied with a stream of air entraining grit particles. A rim of the hood has a continuous resilient seal to contact a worksurface that is to be processed thereby to cut off the hood both from the atmosphere and the interior of the casing. The hood and its seal are shaped to cooperate with a particular worksurface configuration which may be concave, convex, angular, etc. Different hoods are used interchangeably to fit different worksurface configurations.

  • Patent number: 4037290
    Abstract: To remove particles of debris from a floor surface, a hood is mounted on wheels to move over the floor with the open side of the hood facing downward to form a traveling chamber. An air jet nozzle inside the hood is directed downward and is moved in a circular horizontal orbit by a variable speed motor to agitate the debris particles as the hood travels. A pump is attached to the hood to maintain a vacuum therein and to withdraw from the hood a high velocity air stream entraining the agitated debris particles. The hood is manually steered and is driven by a variable speed motor.

  • Patent number: 3974764
    Abstract: A valve for rapidly filling and emptying a volume created by rapid displacement of a machine member. The valve has a body to be connected between a reservoir and the machine. The valve has a valve seat with a seating surface that surrounds the flow path of fluid from the volume and an integral valve guide connected to the seat. A valve opening toward the machine is spring urged toward closed position to withstand high pressure of the fluid at the machine. An auxiliary mechanism is provided to open the valve which may be a solenoid, a pilot piston, or fluid cylinder or manual operation. The valve is provided with a dashpot to provide smooth operation.
