Apparatus to deliver predetermined forces, containers to hold particulate material and media, media, and the associated parameters for operating such equipment along with methods and compositions provided by the apparatus and methods.

A camshaft contains a support tube, on which components including at least one cam are arranged at predetermined locations. The support tube extends at least partially through a hole in the components, and wherein a press fit is produced between the support tube and the components by hydroforming. Accordingly, at least one locally formed material formation is provided between the support tube and the hole. Via the material formation, the component is retained at the location in a desired orientation relative to the support tube in such a way that the support tube having the mounted components can be fed for hydroforming.

A drive gear for a generally cylindrical imaging component. The drive gear includes a body for engaging the generally cylindrical imaging component; a cylindrical shaft attached to the body, the cylindrical shaft having an end surface; and lobes extending longitudinally outward from the end surface.

A roller-bearing mounted shaft may include a shaft tube having a shaft outer face with at least one rolling body running face. The shaft tube may have at least one functional element joined thermally thereto, wherein the shaft tube is formed as a welded and drawn tube and includes a carbon content of greater than 0.45 percent by mass.

A bone, cartilage, and disk removal tool assembly is provided with a motor mounted in a housing. A spindle is mounted for rotation to the housing. A rack-and-pinion mechanism is operably driven by the motor and connected to the spindle to oscillate the spindle for providing a rotary oscillating cutting operation. According to at least another embodiment, a plurality of cams is supported in the housing and driven for rotation by the motor. A plurality of followers is mounted for rotation to the housing, in engagement with the plurality of cams so that one rotation of the plurality of cams oscillates the plurality of followers more than once while preventing over-rotation of the plurality of followers. A peak angular acceleration of the spindle is less than nine million radians per second squared.

Three controls, three variable gear assemblies, a hatch, and a variable torque and power generator (VT&PG), may be used independently and together to provide constant frequency and voltage output power and to increase the amount of output power generated with the same input water flow or wind speed. A three variable spur/helical gear assembly of sun and planetary gear sets is a mechanical three variable control and referred to herein as a Transgear gear assembly, simply Transgear. A hatch wraps around a waterwheel and may control the amount of water inlet to the system by opening and closing and may be controlled by Transgears and a VT&PG. Two Transgears may comprise a constant speed motor control and produce required frequency and voltage and be reduced in part count and complexity. The VT&PG of a marine hydrokinetic or wind power generator may be used as a low torque generator and a high power-rated generator in these applications and may generate more electric power than a conventional fixed power generator (the rotor axially aligned to overlap the stator in a conventional manner) over a wider input range.

The drive gear includes a body for engaging the generally cylindrical imaging component; a cylindrical shaft attached to the body, the cylindrical shaft having an end surface; and lobes extending longitudinally outward from the end surface.

Three controls, three variable gear assemblies, an optional hatch or variable propeller pitch, and a variable overlap generator (VO generator), as well as one or more commutator and brushless free direct current generators may be used independently and together to provide constant frequency and voltage output power and to increase the amount of output power generated with the same input water flow or wind speed in a plurality of embodiments useful in wind power generation and water renewable energy generators for any of tidal and ocean current or wave conditions. Two Transgear assemblies side-by-side and sharing the same central shaft may comprise a constant speed motor control, produce required constant frequency and voltage and be reduced in part count and complexity. The variable overlap generator of a marine hydrokinetic or wind power generator may be used as a low torque generator, a high power-rated generator or a control in these applications and may generate more electric power than a conventional fixed power generator (the rotor axially aligned to overlap the stator in a conventional manner) over a wider input range. An electromotive force (EMF) embodiment generates alternating current at constant frequency and voltage in varying wind and water speed conditions.

A joined prefabricated individual cam includes multiple cams for an adjustable camshaft in particular for an internal combustion engine of a motor vehicle. The camshaft has two shafts mounted concentrically one inside the other, namely an inner shaft and an outer shaft. The joined multiple cam is fixedly pinned to the inner shaft via radial openings provided in the outer shaft with a rotatable bearing on the outer shaft. Such a multiple cam has at least one prefabricated individual cam which is placed as a cam ring on the outside circumference of a carrier pipe at an axial distance from the neighboring individual cams and is fixedly connected to this carrier pipe at a predetermined angle of rotation and axial distance assignment.
