Abstract: The invention is a test apparatus incorporating high current test pins, forced into contact with a circuit assembly under test by opposing compliant pressure pins. An advantageous test pin for low voltage, high current testing is a solid, one piece test pin. The solid test pin, when supplied with adequate contact force, provides both low resistance and low inductance. The required compliant force is applied to the test circuit, opposite and substantially in line with the solid test pin, by a compliant pressure pin. Since the test pin does not supply the compliant force, it can be designed primarily for the desired electrical parameters of the test contact. The only mechanical considerations for the conductive solid pin are the amount of desired surface contact area, the dominant mechanical parameter in setting the contact resistance, and the body dimensions, which determine the resistance and inductance of the pin itself.

Abstract: Pressure-sensitive adhesive-backed labels are carried adhesive back side down on a backing strip. The apparatus completely removes each label from its backing material and then may relocate, manipulate, or hold the label by its adhesive back side before it is attached to a passing article. A group of rollers covered with a nonstick material is located in a frame with their axes aligned along a circumference so that the label is given a reverse curl (to the curl created by the supply roll) before application to the passing article. A solenoid actuated finger holds each label to the rollers while the frame moves to bring the label in contact with the passing article. This arrangement permits the label to be accurately placed on the passing article.

Abstract: Pressure-sensitive adhesive-backed labels are carried adhesive back side down on a backing strip. The present method and apparatus completely removes each label from its backing material and then may relocate, manipulate, or hold the label by its adhesive back side before it is attached to a passing article. The apparatus may be arranged to dispense the labels along an axis parallel to the path of travel of the moving article or along an axis that crosses the path of travel of the moving article.
