The present invention relates to the automatic balance adjusting centrifuge that enhances the efficiency of space utilization by simplifying the structure as well as supports a precise movement by improving the structure of the balance weight transport apparatus in the automatic balance adjusting centrifuge that compensates the unbalance of the centrifugal force by transferring the balance weight equipped in the rotor rotational arm.

According to the automatic balance adjusting centrifuge of the present invention, the structure is simplified as well as the precise and exact transfer of the balance weight is possible by connecting the balance weight with the axis of the motor directly and adopting the length sensor. Furthermore, the efficiency of space utilization is enhanced because the axis of rotation of the balance weight transfer motor is in radial direction of the rotational arm.

The invention alleviates wear on a plow moldboard by achieving a reduction in the effective weight of the moldboard on the roadway. One or more elastic links are interposed between the moldboard and the lifting arm which elevates and lowers the moldboard. The elastic links may be tensioned to such a degree that they serve as a counterweight for the moldboard, transmitting all or most of its weight to the lift arm and the plowing vehicle. The effective weight of the moldboard is thus reduced to such a degree that the lower edge of the moldboard bears against the roadway with little or no force, and it skids or slides along the roadway rather than grinding against it.

A motorized wheel assembly adaptable to skateboards provides drive motor and power sources and controls for the directed control of forward or backward propulsion of the skateboard using throttle and braking controls, the motorized wheel, and all skateboard wheels. Weight transfer assemblies for the motorized wheel transfer a portion of a skateboard rider's weight through the front mounted motorized wheel to the ground surface creating sufficient traction for the motorized wheel to propel the skateboard. One weight transfer assembly embodiment provides a pivoting, compression based mounting bracket. Separate embodiments of the weight transfer assemblies include single or dual shock absorbers.

A rolling kneepad having a weight transfer support assembly with swivel casters to support a user, a kneepad cushion provided above the support assembly to comfortably receive a user's knee, and a shin guard peripherally attached to the support assembly and extending outwardly therefrom. The elongated shin guard has a distal end which abuts the upper surface of a user's shoe or boot. Consequently, when the user moves from a kneeling to a standing position, the weight of the rolling kneepad is supported on the top surface of the user's shoe or boot. Downward slippage of the rolling kneepad along the user's leg is prevented and manual reposition of the rolling kneepad prior to the user resuming a kneeling position is avoided. Straps having hook and loop fasteners at the ends are typically used to affix the rolling kneepad to the body of the user.

A style of footwear, comprising a spring-suspension system, meant for impact absorption and the augmentation of metatarsal thrust. An angle spring affixes to the central pivot point and is external to the shoe sole. A guide and quick recoil are joined to the angle spring in a manner set to influence the central pivot point prior to the deflection of the angle spring itself. A type of resilient compression device is affixed below the ball area of the foot. This device receives the pressure of all aforementioned spring-loaded agents in conjunction with the user's weight transfer, metatarsal thrust, and any residual impact force. The timing of the compression device's load phase is such that it releases in tandem with the unloading of the angle spring. The result is an article of footwear, which works with the natural mechanics of the body to enhance comfort and ability.
