46321489, Dec 30, 1986

Filed:

Sep 5, 1985

Appl. No.:

6/773374

Inventors:

Robert G. Stark - Seattle WA
Tom Stark - Sedro Wooley WA
Robert G. Stark - Portland OR
Joseph W. Anderson - Bellevue WA

International Classification:

F16K 1102

US Classification:

13762418

Abstract:

A hydraulic distribution valve having two substantially identical, molded plastic shells which are joined at their peripheries to form the distribution valve housing. A shaft is journaled within the housing and extends through one of the shells. A rotor is coupled to the shaft and is rotatably disposed within a rotor chamber defined by the housing. Each shell additionally defines a plurality of axially disposed cavities, where at least two of the cavities of the second shell communicate with the rotor chamber. The second shell also defines an inlet which communicates through a gallery which passes through a portion of the shaft and rotor for communication between the inlet and a control port which is defined by the rotor. The shaft and rotor can be rotated to align the exhaust port with a selected cavity to permit communication between the inlet and the selected cavity.

Appl. No.:

6/001743

Inventors:

Joseph W. Anderson - Bellevue WA

Assignee:

Marine Construction & Design Co. - Seattle WA

International Classification:

B01D 2902

US Classification:

210108

Abstract:

A flow-through coalescing separator applicable to clean immiscible liquids and to dirt-carrying immiscible liquids, such as dirty oil and water mixtures. A normally retracted piston periodically backwashes and thereupon compresses the filter body in a pressure vessel so as to purge the filter body of accumulations of dirt and hydrocarbons. When the piston is thereafter being retracted by restoration of input liquid flow pressure, positive coupling of the piston to the filter body stretches it back to its original length and thereby to the full functioning open-pore condition despite wall friction and limited rebound capability of the filter body material. The system lends itself to manually controlled operation and to automatically controlled operation, either in the continuous flow-through mode or in the more frequently interrupted retention flow-through mode. In either mode the system provides predictably-metered backwash liquid volume determined by pressure vessel capacity from its input chamber to the working face of the piston.

International Classification:

F01B 1900
F16J 302

US Classification:

1376255

Abstract:

A valve made from substantially all plastic parts that has integrally molded valve seats. A unique valve disk comprises two identical, mirror-image, molded plastic parts. The parts are of thin-walled construction but are joined together to give the valve body a substantially thick cross section with elongated shear surfaces in the radial direction. End flanges on the seal disk parts mechanically trap the soft sealing material and provide the maximum depth along the force line of contact between the sealing seat and the seal disk. The valve body has a cylinder and a cylinder cap of identically molded, mirror-image parts which house a diaphragm that overlies a plastic domed piston. The domed piston is provided with radially spaced circular ribs for supporting the diaphragm against excess deflection.

Inventors:

Joseph W. Anderson - Bellevue WA

Assignee:

Marine Construction & Design Co. - Seattle WA

International Classification:

B01D 2938

US Classification:

210136

Abstract:

Apparatus for separating water from oil employing a cylindrical, axially compressible, flow-through, oleophilic, hydrophobic reticular foam filter body covered peripherally with and bonded to a flow impervious flexible skin of resin impregnated fabric anchored at one end within a pressure vessel by a flow-through cap assembly sealing the adjacent end of the sleeve to the chamber wall. With the remainder of the sleeved filter body slidably retained and backed within such filter chamber, pressure applied intermittently to its opposite end compresses the filter body to squeeze oil accumulations therefrom. Cap means with one-way valve elements on such opposite end of the filter body permits flow of water through the filter body in one direction while obstructing reverse flow under fluid back pressure introduced into the downstream end of the pressure vessel so as to compress the filter body axially. Back-pressure fluid also entering the narrow gap surrounding the sleeve and the pressure vessel wall helps prevent binding of the accordioning sleeve therein during compression cycles.

Appl. No.:

14/155932

Inventors:

Joseph W. Anderson - Redmond WA, US

International Classification:

B29C 53/56

US Classification:

428 341, 156169, 156433

Abstract:

A manufacturing apparatus for producing filament-wound products such as pressure vessels and pipes includes a mandrel for supporting a pre-form vessel, a mandrel driver structured to rotate the pre-form vessel, and an array of individual filament supports for guiding individual filaments used in producing the vessel. Using the unique aspects of the apparatus which avoids the customary high-angle fiber crossings significantly speeds up manufacturing and thus lowers product cost, increases product lifetime, reduces fatigue stress, and reduces weight of the finished product. Methods of production are also disclosed.
