Appl. No.:

7/152519

Inventors:

Joseph E. Ferri - Shillington PA

International Classification:

B01D 2318

US Classification:

210293

Abstract:

Disclosed is a porous filter support plate of the kind used in traveling bridge filters for the support of granular filter media used in the filtration of waste water, industrial liquors or baths, or for filtration of potable water in a water purification system. The support plates are formed of porous, heat-fusible materials, for example, a thermoplastic organic material, joined together by heat-fused butt joints and/or reinforced by vertical zones which extend vertically through the plates in which the material has been brought to a molten state and is pressed together to form a dense, solid, non-porous mass.

International Classification:

B01F 700

US Classification:

366303

Abstract:

A mixer especially useful for making mechanical foams is disclosed. The mixer includes a stator and a rotor mounted for rotation with respect to the stator, the stator and rotor defining a fluid flow path between them. The fluid flow path includes two shearing zones spaced axially along the rotor. A surface of the rotor extending from the first shearing zone to the second shearing zone defines one boundary of the fluid flow path. The cross-sectional area of the flow path through the mixer is kept substantially constant, varying by no more than about 25 percent, so that zones of stalled flow and low pressure are avoided, thereby maintaining the velocity of the mixture in the flow path relatively high at all times and maintaining a substantial back pressure on the mixture. Portions of the stator and rotor are easily assemblable or disassemblable so that the mixer can be readily converted from a multi-head form to a single-head form.
