A distributor valve for a hydrocutting system. The valve automatically diverts a flow of liquid and solid food products flowing from a source to one or both of two destinations. An entry conduit receives the suspended food products in liquid, and an angled plate deflects the food products downwardly. The food products and liquid enter a drum that is perpendicular to the entry conduit, causing rotational circulation in the drum. The food products and liquid flow into one or both of two longitudinally opposite outlets, depending on whether the path downstream of the outlets is flowing. Upon actuation of a valve on one side, or essentially complete blockage of one side, the fluid and products flow to the other side automatically. No moving parts are needed in the valve to change the flow path; the only change is to the flow downstream, which automatically affects the flow in the valve.

Devices and methods for processing animal or human tissue are provided. The devices may include a vacuum surface to secure the tissue in place and an apparatus for removing fat or other material from the tissue. The apparatus can include one or more blades and/or a fluid jet system.

A novel cutting method and apparatus includes a cutting blade adapted to consistently and easily form a desirable kerf in a concrete substrate while capturing substantially all resulting concrete dust.

A dust collection system for a circular saw having a saw housing and a motor configured to rotationally drive a saw blade includes a dust collecting member and a guide mechanism. The dust collecting member includes a body having a first end in which a dust collection opening is defined and a second end operably connectable to an airflow generation device. The guide mechanism is configured to support the dust collecting member on the saw housing such that the dust collection opening remains adjacent to an outer edge of the saw blade in response to one of the dust collecting member and the guide mechanism contacting the workpiece to move the dust collecting member.
