US Patent:

48971928, Jan 30, 1990

Filed:

Dec 28, 1988

Appl. No.:

7/291050

Inventors:

William J. Lawrence - Kemah TX

International Classification:

B01D 3322

US Classification:

210330

Abstract:

A filtration device includes in a pressure vessel a driven rotary shaft having a longitudinal bore. Fluid suspension to be processed to recover the fluid is expelled from distributing conduit, situated either in the shaft or in the vessel, the outlets of which open to the cavity of the pressure vessel at central processing zones proximate the shaft adjacent the radially inward portions of annular filtration discs secured to the shaft. The filtration discs are laminates in which an inner conducting support layer is enclosed by an outer filtration layer. The layers are porous, the pores are in fluidic communication, and the pores of the inner layer are larger than the pores in the outer layer. Fluid collecting in the outer layer of a spinning filter disc flows from the inner layer through collecting passageways to the longitudinal bore in the shaft, and is removed from the vessel through a conduit fluidly communicating with longitudinal bore.

Appl. No.:

6/208245

William R. Lawrence - Houston TX

Assignee:

Hersey Products, Inc. - Dedham MA

International Classification:

G02B 514

US Classification:

250227

Abstract:

A method and apparatus for detecting and measuring mechanical movement that is directly or indirectly representative of a physical phenomenon. The method and apparatus involve the use of at least one optical fiber that defines a region of bend having a curvature, the radius of which varies in direct relation with the particular mechanical movement that is induced by the physical phenomenon. Light is introduced into one extremity of the optical fiber and propagates through the fiber where the intensity of the light emitted or radiating from the opposite extremity of the fiber is measured. Differentiation between introduced light and emitted light determines the degree of perturbance caused by the region of bend and is thus representative of the physical phenomenon that alters the radius of curvature at the region of bend.

International Classification:

B01D 3322

US Classification:

210330

Abstract:

A filtration device includes in a pressure vessel a driven rotary shaft having a longitudinal bore into which fluid suspension to be processed to recover the fluid is pumped. The suspension is expelled into a processing zone in the vessel from distributing passages fluidly communicating the bore to the cavity of the pressure vessel. The processing zone is adjacent filtration discs affixed to the rotating shaft. The filtration plates are laminates in which an inner conducting support layer is enclosed by an outer filtration layer, the layers being porous, the pores being in fluidic communication, and the pores of the inner layer being larger than the pores in the outer layer. Fluid collecting in the outer layer of a spinning filter disc flows from the inner layer through collecting passageways to a second longitudinal bore in the shaft, and is removed from the vessel through a conduit fluidly communicating with such second longitudinal bore.
