6626764, Sep 30, 2003

Filed:

Jun 14, 2001

Appl. No.:

09/868413

Inventors:

Paul J. Cornay - Longmont CO 80501

International Classification:

F16D 333

US Classification:

464117, 464905

Abstract:

A universal joint ( ) includes a centering device ( ) for supporting the universal joint and forcing the two joint halves to operate at the same angle thereby causing the joint to operate at constant velocity at all angles. Each shaft ( ) of the joint ( ) is connected to the centering device ( ). Movement of one of the shafts ( ) at an angle relative to the longitudinal axis of the coupling device ( ) is transmitted to the other shaft ( ) by the centering device ( ) and the centering device ( ) causes the other shaft ( ) to likewise move at the same angle relative to the longitudinal axis of the coupling device ( ). The centering device ( ) includes a cam bearing (cam ) longitudinally aligned with a cam bearing (cam ), which arrangement of cam bearings allows a full range of movement of the shafts ( ).

Abstract:

Universal joint ( ) includes a centering mechanism ( A) for supporting the universal and forcing the two joint halves to operate at the same angle thereby causing the joint to operate at constant velocity at all angles. Each shaft ( ) of the joint ( ) is rotatably connected to the centering mechanism ( A). Movement of one of the shafts ( ) at an angle relative to the longitudinal axis of the coupling yoke ( ) is transmitted to the other shaft ( ) by the centering mechanism ( A) and the centering mechanism ( A) causes the other shaft ( ) to likewise move at the same angle relative to the longitudinal axis of the coupling yoke ( ). The centering mechanism ( A) includes cam rods ( ) supported within a cam tube ( ), which arrangement allows a full range of movement of the shafts ( ) at angles of 90 Â.

Appl. No.:

09/707430

Inventors:

Paul J. Cornay - Longmont CO

Assignee:

ERTH Technologies, Inc. - Longmont CO

International Classification:

B04B 502

US Classification:

494 33, 494 51

Abstract:

A centrifuge for decanting lighter material from heavier material from a mixture of initial material includes a housing having a central body and a hollow arm extending from the body, the arm having a first end attached to the central body, and a second end extending away from the central body, and an end cap attached to the second end of the arm to form a chamber in the arm. A baffle is attached to the body and extends into the chamber, the baffle having a longer inner tube having an interior and a distal end, and a shorter outer tube. The longer tube is positioned inside the shorter tube and defines an inner space therebetween. An outer space is defined between the shorter tube and the hollow arm. An entrance path for the mixture of initial material is formed in the housing and communicates with the inner space. An exit path for the light material is formed in the housing and communicates with the outer space.

US Classification:

Abstract:

A two-tube centrifuge separates light material and heavy material from an input mixture. A hollow drive shaft rotates a central body member about an axis of rotation. Two hollow arm assemblies, each having circular cross-section, are mounted on diametrically opposite sides of the central body. Each arm assembly includes an outer housing tube, an intermediate tube, and an inner tube that is longer than the intermediate tube. An end cap having a removable plug is mounted on the outer end of the housing-tube of each arm assembly. The inner ends of all three tubes are mechanically interlocked in a manner to cantilever mount the inner and intermediate tubes to the central-body with their outer ends spaced from the internal surface of the end cap. An input-mixture path extends through the hollow drive shaft, through the central-body, and into a cylindrical space between the inner and intermediate tubes of each arm assembly. A heavy material exit path extends from the inner tube, through the central body, and into an exit cone that lies diametrically opposite the drive shaft and whose axis is coincident with the axis of rotation.

US Classification:

494 31, 494 51

Abstract:

A centrifuge having a housing having a body and an arm extending from the body, the arm attached to the body at a first end; a chamber defined in the arm; a first tube positioned within the chamber and comprising a porous sidewall; a second tube positioned within the chamber; a first flow path defined by the first tube and second tube; a second flow path defined by the second tube; a first exit in communication with the first flow path for evacuating a first material from the arm; and a second exit in communication with the second flow path for evacuating a second material from the arm. An input mixture enters the arm through an inlet. As the sludge flows along an outer flow region defined by the first tube and interior sidewall of the arm, at least a portion of a liquid passes through the porous sidewall of the first tube and into a middle flow region, analogous to the first flow path. The liquid may drain from the middle flow region through the first exit. Solids exit through the second exit.
