Abstract: A waterjet safety enclosure formed by walls using a detection device or light curtain to detect unsafe conditions. The waterjet safety enclosure walls can be used in new work areas or retrofitted and shaped to fit existing work areas. The waterjet safety enclosure walls may form a partial or complete perimeter about a work area and may be adjustable or mobile. The waterjet safety enclosure wall detects unsafe conditions when a high pressure stream of water from a waterjet cutting machine approaches, contacts or penetrates the waterjet safety enclosure wall. The detection device detects the high pressure stream of water and sends a signal to a controller to stop the operation of the waterjet cutting machine.

Abstract: An automatically adjustable abrasive recycling system is provided. The abrasive recycling system includes one or more sensors configured to sense at least one characteristic of the abrasive recycling system, and slurry supply mechanism that operates, at least in part, based upon the sensed characteristic to control the operation of the abrasive recycling system. Methodology corresponding to the automatic operation of the abrasive recycling system is also provided.

Abstract: A preferred embodiment of the present invention relates to an abrasive recovery apparatus for use in conjunction with the slurry generated by water jet cutting or conditioning operations. The generated slurry is comprised of both non-recyclable fines and recyclable particles. The abrasive recovery apparatus comprises a slurry intake system having one or more pumps which collect and distribute slurry. The abrasive recovery apparatus further comprises a vibrating separator having a filter sized and shaped such that the non-recyclable fines in the slurry are separated from the recyclable particles in the slurry. The abrasive recovery apparatus still further comprises a fluidized bed dryer having heating elements to dry the recyclable particles.
