A catheter device regulates fluid flow within a circulatory vessel. Included is an elongated catheter body configured to access one of a circulatory vessel or a heart chamber. The catheter body includes a proximal end, a distal end, and a first lumen including an open proximal end and a distal end with a port formed at a distal portion of the distal end. A second lumen is also included in the catheter body with an open proximal end. An antegrade valve is coupled to an exterior of the catheter body and configured to provide a controllable antegrade flow and a controllable retrograde flow along the exterior of the catheter body. The antegrade flow is greater than the retrograde flow. A retrograde valve may be included which provides a controllable retrograde and antegrade flow along the exterior of the catheter body. When a retrograde valve is used, the retrograde flow is greater than the antegrade flow.

A foam generator includes a body and a removable insert positioned within the body. The insert is held to the body by a cap releasably engaging a mating surface of the body. The body includes a plurality of inlets for foam constituents adjacent the mating surfaces of the body and an outlet for the foam opposite end. To change the insert, the can is disengaged from the mating surface without the need for tools and without disturbing the inlets. A new insert can be placed within the body and a cap of the new insert engaged with the mating surface without the need for tools.

A process for making a decorative sheet material includes applying a first printed pattern to a web as the web travels over a first printing cylinder having a first diameter, and applying a second printed pattern to the web as the web travels over a second printing cylinder having a second diameter, which is different than the first diameter. A system for making a decorative sheet material includes a first printing cylinder for applying a first printed pattern on a web travelling over the first printing cylinder, and a second printing cylinder for applying a second printed pattern on the web travelling over the second printing cylinder. The first printing cylinder has a first diameter. The second printing cylinder has a second diameter, which is different than the first diameter.

What is presented is a permanent magnet drum separator for removal of a ferrous fraction from a material stream comprising a pickup magnet that is a rare earth permanent magnet that can be moved within the drum separator. The drum separator comprises a rotatable outer shell having tubular shape with a circular cross section. The drum separator includes a carry magnet that is positioned at a fixed location within the rotatable outer shell near the inside circumference of the rotatable outer shell. The pickup magnet is positioned on a hinge plate within the rotatable outer shell. The hinge plate has a first end attached to a hinge and a second end attached to a movable element. The hinge is positioned at a fixed location within the rotatable outer shell near the inside circumference of said rotatable outer shell. The movable element is able to move the pickup magnet about the hinge to vary the distance between the pickup magnet and the inside circumference of the rotatable outer shell.

Drivetrains and frames for vehicles, equipment, machines, etc. Some embodiments of the drivetrains and frames are particularly suited for human powered machines, such as bicycles and exercise equipment. In some embodiments, a drivetrain includes a reciprocating crank coupled to a crank pivot. A lever couples to the crank via a lever pivot positioned on the crank. A lever stop cooperates with a lever guide surface to guide a motion of the lever as the lever pivots about the lever pivot. The lever and/or the crank are operably coupled to a drive pulley, idler pulley, and/or compound pulley. In some embodiments, a drive cable operably couples the lever and/or the crank to the drive pulley, idler pulley, and/or the compound pulley. In one embodiment, one or more pulleys couple to the lever's distal ends. In some embodiments, the drivetrain includes a wheel hub adapted to receive torque from the crank via a drive pulley.
