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.

Abstract: Universal joint (100) includes a centering mechanism (100A) 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 (134, 135) of the joint (100) is rotatably connected to the centering mechanism (100A). Movement of one of the shafts (134, 135) at an angle relative to the longitudinal axis of the coupling yoke (136) is transmitted to the other shaft (135, 134) by the centering mechanism (100A) and the centering mechanism (100A) causes the other shaft (135, 134) to likewise move at the same angle relative to the longitudinal axis of the coupling yoke (136). The centering mechanism(100A) includes cam rods (102, 103) supported within a cam tube (101), which arrangement allows a full range of movement of the shafts (134, 135) at angles of 90°.

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.

Abstract: The invention relates to sub-critical processes and systems for accomplishing the same. In one aspect, the process is a sub-critical oxidation process for the destruction of organic and inorganic contaminates within a waste fluid or gas. The sub-critical processes are preferably carried out in a reactor and/or continuous flow centrifuge operating at sub-critical temperature and pressure. The processes and systems provide for destruction of high levels of organic and inorganic contaminates within a contaminate source, which represents a vast improvement over other conventional approaches. The processes and systems also accomplish this superior destruction of contaminates in a much faster time frame, i.e., minutes as compared to hours. Finally, the processes and systems described herein provide a safe and highly economical sub-critical approach as compared to the super-critical conditions, i.e., exceeding high temperatures and pressures, used in most conventional approaches.

Two hollow arm assemblies, each having circular cross-section, are mounted on diametrically opposite sides of the central body. Each arm assembly includes internal tubes generally configured as 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.
