Title: Uniform dielectric heater for goods - has container immersed into dielectric liquid and exposed to HF field, with top of container additionally heated
Inventor: BACH JEAN DR
IPC: H05B6/78
Filed: 1976-12-14
Abstract: The goods, e.g. yogurt are filled in insulating containers with an empty space above them inside the container. The filled container is immersed in a liquid to nearly the level of goods in the container. The liquid permittivity is approx. equal to that of the goods. Then the whole is subjected to a homogenous h.f. electromagnetic field, so that the whole volume of goods except the top layer is heated. The part of the goods projecting above the liq. level, and of the container enclosing the empty space above the goods, is heated by application of additional heat to approx. the same temp. as the rest of the goods. This is dome immediately before, or during, or immediately after the exposure of the container to the electromagnetic field.

Title: Density indicator for encapsulated gas filled switch enclosure - uses float with counterbalancing spring visible through window
Inventor: HOLLMANN FRITZ
IPC: H02B13/055
Filed: 1978-06-22
Abstract: The indicator (1) comprises a float which is filled with a gas less dense than the insulating gas used in the enclosure (16). The indicator is attached to a lever arm (3) which is pivoted (2) and coupled to a counter balancing spring (4).
