Latest Patents

Frisch’s listed patents address distinct stages of specialized manufacturing.

“High Throughput Assembly Station and Method for Image Intensifier Tubes” describes an automated system for assembling photocathodes into vacuum-tube housings. The photocathodes and housings are processed in separate evacuated chambers that remain interconnected as a common vessel. An automated mechanism transfers the photocathodes between chambers, where they are joined to the housings to form vacuum-tube assemblies.

“Channel Evaporator” concerns an evaporator designed to deposit a second material onto a remotely located surface after a first material has been evaporated. Its tubular member has crimped ends to keep the materials separate during the first evaporation, along with an aperture on a flattened area that allows the second material to escape during its evaporation.

Career Highlights

The two listed inventions reflect Frisch’s work on manufacturing equipment and material-deposition processes. One focuses on automating the assembly of image intensifier tubes, while the other addresses the controlled release of materials during evaporation.
