Method of discriminating kinds of golf balls
First Claim
1. A method of discriminating solid golf balls from thread-wound golf balls which comprises the steps of holding the golf ball to be discriminated between a transmitter coupled to means for oscillating ultrasonic wave and a receiver coupled to means for detecting the ultrasonic wave received by said receiver, applying from said transmitter, the ultrasonic wave having a frequency which can propagate through said solid golf ball, but can not propagate through said thread-wound golf ball, to said golf ball to be discriminated, and detecting presence of the ultrasonic wave reaching said receiver through said golf ball to be discriminated by said ultrasonic wave detecting means.

Abstract
A method of discriminating solid golf balls from thread-wound golf balls which includes the steps of holding the golf ball to be discriminated between a transmitter coupled to an ultrasonic wave oscillator and a receiver coupled to an ultrasonic detector for detecting the ultrasonic wave received by the receiver, applying from the transmitter, the ultrasonic wave having a frequency which can propagate through the solid golf ball, but can not propagate therethrough, to the golf ball to be discriminated, and detecting presence of the ultrasonic wave reaching the receiver through the golf ball to be discriminated by the ultrasonic wave detector.
