Abstract: A solid-state radio frequency (SSRF) water heating apparatus is disclosed. In embodiments, the SSRF water heater includes a water tank, SSRF generator array and RF sensors enclosed within an RF-shielded cage. The SSRF array synthesizes RF signals in the microwave range and transmits the RF energy through the water tank, exciting and heating the water molecules without direct contact. The RF sensors at the opposite end of the tank sense residual RF energy not absorbed by the water. Control processors regulate the generation and transmission of the RF energy based on the sensed residual energy. The heated water and/or generated steam is piped to hot water dispensers, beverage makers, or steam ovens.

Abstract: A system may include an aircraft galley insert; an aircraft galley insert motor mount; and an aircraft galley insert motor. The aircraft galley insert motor may include: a motor housing; a dynamic seal seat extending from an exterior of the motor housing toward the aircraft galley insert motor mount; a dynamic seal installed within the dynamic seal seat and on the exterior of the motor housing, the dynamic seal preventing matter from an inner cavity from entering an interior of the motor housing; and a shaft driven by the aircraft galley insert motor, the shaft extending from within the aircraft galley insert motor, through the motor housing, through the dynamic seal, and into the inner cavity of the aircraft galley insert, wherein the dynamic seal forms a seal around the shaft as the shaft is driven and as the shaft is deflected at least by gravity effects, turbulence, and vibrations.
