Abstract: A cathode heater assembly for use in a vacuum electronic device comprises a refractive cup having a bottom portion and side walls forming a container; a cathode secured in the container of the refractive cup; and a heater wire coupled to the refractive cup. The cathode heater assembly may be manufactured by providing a refractive cup having a bottom portion and side walls forming a container; inserting a cathode pellet in the container of the refractive cup; impregnating the cathode pellet with electron emissive materials while the cathode pellet is in the container of the refractive cup; and attaching a heater wire to the refractive cup.

Abstract: A conveyor belt assembly with a housing profile that protects components positioned in an interior of the housing from spilt products and is easier to clean than previously known conveyor belt assemblies. The conveyor belt assembly of this invention includes a frame with a sloped surface positioned under the conveyor belt such that spilt product that falls through the conveyor belt lands on the sloped surface and gravity pulls the spilt product off the sloped surface to a side of the housing for easy clean up.

Abstract: A sun visor includes an annular band for securement of the sun visor about an individual's uppermost head portion, wherein the sun visor includes an eyeglass assembly mounted rotatably to a concave portion of the sun visor, wherein a photocell in cooperation with a battery and solenoid drive is arranged to effect rotation of the eyeglass assembly to a lowered second position from a raised first position that is in adjacency to the sun visor concave surface in response to available sunlight.
