Title: Magnetic filter
Inventor: KUWABARA TAKESHI
IPC: B03C1/034
Filed: 1979-12-27
Abstract: PURPOSE:To riase both the removing and back washing-regenerating effects of magnetic fine particles by designating the ratio of the filling density to the radius of a filter element consisting of strong ferromagnetic fine filaments within a specific range. CONSTITUTION:Perforated plates 8 and 9 are fixed in parallel at a fixed interval by means of a fixing bar 10, and filter elements 2 are evenly filled between the perforated plates 8 and 9. In this case, the ratio of the filling density (the ratio of the whole volume of filter element to the volume of a filter container) to the radius (in mm.) of the filter element is designated within a range of 0.5-1.4. A current is applied to an exciting coil 1 to generate a magnetic flux in parallel with the flow direction inside the filter container 3, thereby magnetizing the filter element 2. Under such a condition, a slurry containing magnetic particles is supplied from an inlet pipe 5 into the container 3, whereupon the magnetic particles are adsorbed and arrested on the filter element 2 and then clean slurry is discharged from a pipe 6.

Abstract: PURPOSE:To prevent slips or clattering between a metal cylinder and a die casting and to transmit rotational torque to a rotary shaft securely, by a method wherein knurling is provided on a contact surface of the metal cylinder with the die casting. CONSTITUTION:A cylindrical permanent magnet 3 to constitute a rotor is covered on its outer circumference by a non-magnetic cylinder 4, and fixed to a metal cylinder 1 by a die casting 2.
