Title: Pivotably mounted ultrasonic testing apparatus
Inventor: CORNFORTH ALEXANDER RANKIN
IPC: G01N29/26
Filed: 1987-11-06
Abstract: An ultrasonic testing apparatus comprises a shoe 3 rotatable about a tube 8 to be tested and includes at least one pivotally mounted arm 2 having at one end the shoe 3 housing an ultrasonic transducer probe and at the other end a counter-weight in the form of a chamber 1. Control means are provided to introduce liquid into, and exhaust liquid from, the chamber 1 whereby the centrifugal force generated during rotation urges the probe into or out of engagement with the tube in dependence on the mass weight of the chamber. To raise the shoe 3 from the tube 8 a control signal passes through closed contacts 10 of a microswitch 9 and a valve 5 opens an outlet port 13 to exhaust the chamber 1 and the arm 1 then pivots away from the tube 8. At the limit of travel, the arm actuates the microswitch 9 to open contacts 10 and change the state of the valve 5 so as to close the outlet 13 and open an inlet to fill the chamber again. Contacts 17 then close to open an inlet to a valve 6 which actuates a hydraulic stop cylinder 11 and a stop 4 arrests the arm 1. To lower the shoe, a control signal changes the state of valve 6 to exhaust the cylinder 11 and retract the stop 4. In another arrangement, mercury is transferred between two chambers on opposite sides of the arm pivot. The pivotal action prevents transducer damage at unfinished ends of the tube, which may be irregular. <IMAGE>

Such arrangement makes it easy to spin and release the ball and to control the spin of the ball. A release device for feeding a ball to the hitting device comprises blower means (101) for sending forth air to the outlet through a release passage communicated with the upstream of the outlet, and feeding means for feeding balls one by one to the release passage. Such arrangement enables the ball released on the circular runway to be accelerated thereon.
