Abstract: Abstract of the Disclosure Apparatus for detecting predetermined irregularities in the contour of the sidewalls of a tire includes transducer probes which are selectively positionable adjacent to the sidewalls of the tire.  As the tire is rotated, the output signals of the probes, which are proportional to sidewall contour, are received by a signal processing circuit which determines the rate of change in contour of the sidewall, and compares that rate of change with a preselected rate of change.  The period in which the actual rate of change might exceed the preselected rate of change is timed and if that period lasts longer than a preselected time period, an output signal alerts the operator that a predetermined irregularity exists.  In this manner, small normally occurring irregularities are ignored but larger undesirable irregularities are automatically detected.

Abstract: Abstract In a water ski harness, the unit forming the connection between the bridle and the skier's tow line is provided in the form of a combined float and coupler.  The unit is formed by an elongate buoyant body of low-density material having in place of the conventional pulley, a transverse channel one side of which is formed by a low friction surface of P.T.F.E.  The bridle extends through this channel along the surface so that the unit can move in an unimpeded fashion longitudinally of the bridle.  At the rear end of the body there is a longitudinal aperture the forward end of which communicates with a transverse through aperture, there being a pair of grooves formed on the rear end positioned to opposite sides of these apertures.  Thus, a simple connection to the tow line is provided by passing the looped end of the tow line into the longitudinal aperture, laterally out one side of the transverse through aperture, and then spreading the loop so that opposite sides of it lie in the two grooves.  Tension forces applied to the tow line will thus tighten the loop and bind it securely to the rear end of the body.
