    Abstract: Apparatus for changing a mask used in the evaporation of thin film electronic components formed on flexible substrates by vapor deposition techniques, whereby a number of masks are successively brought into registration with a substrate for sequentially depositing a series of thin films of selected materials including semiconducting, insulating, or conducting materials through the mask onto the substrate. The apparatus is particularly concerned with alignment pins for enabling registration of successive patterns to be vacuum evaporated successively onto one area of a flexible substrate tape with an accuracy of + OR - 1 Mu . The area of the substrate tape may be changed and the process repeated time after time without opening the vacuum system.

    Abstract: An apparatus for providing power for transmitting relaying signals from an extra high voltage transmission line to ground potential which avoids the use of a high cost current transformer and which is immediately effective to provide such signals when the transmission line is initially energized to protect such line if it is energized when a fault is present. The apparatus supplies the power from ground potential to line potential by means of sonic quantity transmitted from a first transducer to a second transducer through an elongated rod-like insulating member which preferably is caused to vibrate at its resonant frequency.
