Abstract: An electron gun apparatus comprises a cathode subassembly which is movably mounted relative to a fixedly mounted and registered grid/anode subassembly to permit mechanical adjustment of the cathode with respect to the grid/anode subassembly. An evacuated chamber, including resilient bellows interconnecting the movably mounted cathode assembly to the fixedly mounted grid/anode subassembly for permitting the mechanical adjustment, houses the cathode and the grid/anode subassemblies. Means are provided for electrical energization of the cathode, the grid, and the anode. According to a further feature of the invention, the cathode comprises a line filament, and the grid and the anode are slotted for providing an elongated line image.

Abstract: An electrically powered actuator for providing a rotational or large linear motion, which is simple and highly reliable, including a bi-metallic strip with a slot extending along its length from one end to a position near the opposite end. In a rotational actuator, the strip is bent into a spiral, with the inner turn fixed to the shaft which is to be rotated and the outer turn fixed to a support and connected to electrical leads. Current passed through the leads and through the slotted strip heats it to make it uncoil or to make it coil further, the several rotations of the strip resulting in a large rotation of the shaft.
