摘要： An inlet conveyor for conveying tires through a tire uniformity testing system includes a tire centering mechanism and a pair of conveyor belts for delivering tires to a tire testing station. A fixed conveyor having rollers on which tires can easily slide is secured to a frame that supports the centering mechanism. The conveyor belts are reeved around respective pulleys and are supported by support rails fixed to and extending away from the centering mechanism in cantilever fashion. A conveyor elevator is raised or lowered with respect to the frame unit to raise or lower the support rails and conveyor belts to either engage or disengage a tire resting on the fixed conveyor. The support rails and conveyor belts are adjustable in a lateral direction to vary the width of the space between the belts to accommodate different size tires. The conveyor belts are advanced by a rotary pneumatic actuator that precisely controls the distance the belts move to position the tire with respect to the testing station. The inlet conveyor is mechanically isolated from the testing station so that disturbances affecting the inlet conveyor are not transmitted to the testing station. The inlet conveyor is movable with respect to the testing station to reverse the direction of tire flow through the testing machine.

摘要： A method and apparatus for measuring the wall thickness of insulated pipe of various sizes, shapes and locations without requiring removal of the insulation. The apparatus includes a source which emits a collimated beam of low-level radiation and a detector adapted to detect the beam. The source and detector are pivotally mounted on trucks which in turn are movably mounted on frame assemblies which include rotatable shafts. Stepping motors are mounted on the frame assemblies and are drivingly connected to the shafts for rotating the shafts. Indexer devices are connected to a computer and to the motors for controlling the rotation of the shafts. Motion translators are mounted on the trucks and are operatively connected to the shafts for translating the rotational motion of the shafts into linear motion. The source and detector are located in aligned, opposed spaced relationship adjacent to the pipe. The stepping motors simultaneously linearly move the trucks, and the source and detector mounted thereon, in discrete linear steps along the shafts for scanning the pipe to take discrete measurements of the pipe wall thickness. The radiation beam emitted by the source passes through the insulated pipe and is detected by the aligned detector at each discrete step. A single channel analyzer device connected to the detector measures counts of unattenuated radiation beams detected by the detector. A computer is connected to the single channel analyzer through an interface and generates computer profiles of the pipe wall thickness.
