Abstract: An apparatus for mounting a scrubber pressure vessel to a base. The scrubber has a skirt which is mounted directly onto the base. The base has two orthogonal longitudinal beams. The beams are oriented with respect to the pressure vessel such that the forces directed to the scrubber by its attached piping are parallel to one of the beams. The skirt is attached to the base on the longitudinal axes and the connections may vary in stiffness such that the natural frequencies of the system along both axes can be adjusted to avoid the operating frequency which would otherwise result in resonance.

Abstract: A pocket-sized golf backswing training device is provided having an elongated hinged tee which has a rod-like lower portion insertable into the ground. A ball is secured to a top of the hinged tee. The tee is movably retained in a predetermined upright position by a positioning means such as a cooperative engagement between upper and lower tee portions. In an embodiment, the upper and lower tee portions are pivotally hinged together by a pin extending through overlapping narrowed segments of the respective tee portions. The device is planted in the ground, positioning the ball in a desired backswing path of a golf club. A practicing golfer then swings the club rearwardly. When a proper backswing is executed, the ball is struck by the club head, tipping the device to a pivoted position. The pivoting of the tee indicates to the golfer that a proper backswing has been executed.
