Abstract: A high-speed process for coating substrates with thin organic coatings in a vacuum is disclosed and claimed. The process utilizes relatively low boiling, reactive monomers (e.g., polyacrylates) which are flash vaporized, condensed on the substrates and cured, in situ. The resultant cured films are pin-hole free and exhibit excellent adhesion. The process is capable of being run at very high coating and curing speeds, e.g., between 1 and 1000 cm/second.

Abstract: A liquid vaporizing apparatus having a cylindrical heated vaporizing surface against which atomized droplets of liquid are thrown by a spinning disk; the disk receiving a continuous thin film of liquid from a capillary tube spaced from the disk so that a fluid drop fed from the tube end is contacted by the disk to roll the drop while pulling a liquid film from the drop, the liquid being continuously replenished from the tube.
Abstract: An atomizer with a capillary passage to a tip surface which is vibrated by a directly coupled ultrasonic device to disperse droplets of liquid fed to the passage. The tip is associated with a heated vaporization chamber, and a cooling chamber between the tip and the ultrasonic device protects the device from the heat of the chamber.
Abstract: An RF filter connector with a one-piece housing formed of conductive material, a plurality of contacts, insulating spacers, high frequency filter elements on selected or all contacts, a conductive ground plane in conductive engagement with each filter element and the housing, and a spring clip member for clip mounting on the connector housing. When mated with another connector, the RF filter connector housing and the other connector housing will be maintained in conductive engagement to effect reliable EMI grounding of undesired signals. An RF filter connector having components which may be readily hand asembled or be automated machinery.

Abstract: An electromagnetically shielded viewing window for an enclosure including a wire mesh member formed of respective crossing wires bonded between a pair of transparent panels, wherein the wire cross points are joined by nickel/copper plating of the wire mesh without covering the mesh open areas. A dull coating of antiqued silver is applied to the plated wire mesh to reduce window glare. A wire gasket extends around the panel perimeter, and a wire mesh portion projects beyond one of the panels and overlies the wire gasket to reliably ground the wire mesh when mounted to the enclosure.
