Valve seat pores sealed with thermosetting monomer
Hard anodic coating provides a smooth wear resistant value seating surface on a cast aluminum alloy valve body. Vacuum impregnation with a thermosetting monomer, diallyl phthalate, seals the pores on the coating to prevent galvanic corrosion.

Dust particle injector for hypervelocity accelerators provides high charge-to-mass ratio
Injector imparts a high charge-to-mass ratio to microparticles and injects them into an electrostatic accelerator so that the particles are accelerated to meteoric speeds. It employs relatively large masses in the anode and cathode structures with a relatively wide separation, thus permitting a large increase in the allowable injection voltages.

Electroplating eliminates gas leakage in brazed areas
Electroplating method seals brazed or welded joints against gas leakage under high pressure. Any conventional electroplating process with many different metal anodes can be used, as well as the build up of layers of different metals to any required thickness.

Nixie tube display unit employs time-shared logic
Cathodes of display tubes wired in parallel achieve input switching simplification of a Nixie tube display system. Use of time- shared logic energizes the appropriate anode and inhibits all unnecessary cathodes.
