Abstract: A vehicular drive shaft assembly is balanced about an axis of rotation. The vehicular drive shaft assembly includes a drive shaft tube having a first end and a second end, with a first tube yoke including a first radially outer wall fixedly mounted to the first end of the drive shaft tube. A first balance pendulum is located radially inward of the first outer wall and rotationally fixable relative to the first tube yoke, and a second balance pendulum is located radially inward of the first outer wall and is also rotationally fixable relative to the first tube yoke. The balance pendulums can be rotated before being locked in place in order to account for imbalances in the drive shaft assembly. A second tube yoke fixedly mounted to the second end of the drive shaft tube may also include balance pendulums, similar to the first, in order to provide additional drive shaft assembly balancing capabilities.

Abstract: An apparatus for cleaning a golf putting path including a hand grip portion, an elongate shaft secured to the hand grip portion, and a head secured to an opposite end of the shaft. The hand grip, shaft, and head are collectively sized and arranged to resemble a golf club and further they include a compressed gas cartridge, a discharge nozzle, and a valve in fluid communication with the compressed gas cartridge and the discharge nozzle for controlling flow of gas from the compressed gas cartridge to the discharge nozzle.
