Abstract: A labeling machine wherein there is a picker reciprocably movable between a label magazine and a transfer position for transferring labels to a gripper assembly at the transfer position whereupon the gripper assembly takes the label from the picker and applies it to a container and wherein there is an adhesive pick-up roll supported in a container of adhesive and a transfer roll reciprocably movable in timed relation to the movement of the picker to transfer a coating of adhesive from the pick-up roll to the surface of the picker; characterized in that the transfer roll is a driven roll and is rotated while in contact with the pick-up roll at least one complete revolution, and further characterized in that while in contact with the surface of the picker is rotated no more than one complete revolution as it travels from one end of the picker surface to the other end thereof.

Abstract: Fused silicide coatings for protecting niobium alloy substrates are modified by providing dispersed nucleation sites in the form of discrete particles in the coating. The discrete particles have a thermal expansion coefficient lower than that of the fused silicide material. This alters the microstructure and reduces the thermal expansion coefficient of the coating so as to minimize the number of tensile cracks.
