Abstract
Abstract An automatic machine for inspecting electric capacitors is disclosed. The machine includes a rotating turret having a number of capacitor supports which carry the capacitors through a series of automatic test stations. The stations automatically determine a number of characteristics of one or more sections of the capacitors such as voltage retention, terminal to cover insulation value and capacity. The machine marks and rejects capacitors which do not meet preset voltage retention, insulation, and capacity values and also separates acceptable capacitors into a number of separate differently coded groups according to their particular capacitance value range.
