Abstract: This invention comprises a method and an apparatus for separating solids from fluids in fluids containing high total suspended solids and where the solids are of a broad particle size including ultra fine particles. A fluid volume is passed through a filter element thereby separating the solids from the liquid. The solids deposited on and in the filter element are cleaned from the filter element by a continuous backwashing process using pressurized filtered fluid in excess of the fluid pressure of the fluid on the intake side of the filter. The rate at which backwashing occurs and the pressure of the pressurized filtered fluid used in backwashing is increased when the pressure differential between the intake and outlet volumes increases.

Abstract: An electron beam generator includes: an electron emitting cathode (1); an anode (3) with an anode bore (4) for the passage of an electron beam (6); a Wehnelt electrode (2) between the cathode (1) and the anode (3) for controlling the electron beam; the cathode (1); the anode (3) and the Wehnelt electrode (2) disposed within a vacuum chamber (100); and a magnetic unit (7) disposed between the cathode (1) and the anode (3) for generating a static transverse magnetic field causing the electrons to be deflected along a curved path until the electrons enter the anode (3) such that ions follow an ionic path back to strike the Wehnelt electrode (2) and are kept from striking the cathode (1) by displacement caused by the ionic path. The present invention reduces the number of ions that impact the cathode and reduces the number of ions that are formed by the ionization of residual molecules, increasing the service life of the cathode.

Abstract: A high capacity filter apparatus for removing solids from fluids includes a opposing filter elements defining an internal volume. Fluid to be filtered passes through the filter elements into the internal volume and through an outlet. The filter element is continuously cleaned by backwashing along the outer surface of the elements.

Abstract: Filter apparatus for continuously filtering fluids containing large amounts of particles, including large amounts of ultrafine particles. The filter apparatus includes filter media and a backwash system which continuously removes deposited filtrate from an inlet side of the filter media. The filter apparatus also includes means for at least temporarily retaining filtered fluid in an outlet chamber of the apparatus at a location immediately proximate an outlet side of the filter media, such that backwashing of the filter means occurs continuously and instantaneously as filtered fluid passes through the filter means.

Abstract: A drive mechanism for a pair of forging or stretching rollers comprising a hydraulic system including a pump, a hydraulic motor and switching means interposed between a main drive motor and the rollers.
