Electric capacitor of variable capacitance
First Claim
1. An electric capacitor of variable capacitance, comprising:
- a dielectric body comprised of densely sintered ceramic material;
the body having a hollow space extending through it for holding liquid dielectric therein;
the body having spaced apart surfaces generally at opposite sides of the hollow space;
capacitor plates in the form of metal layers on the spaced apart surfaces of the body, and the plates being separated by the hollow space for defining the capacitor plates;
the capacitor plates both having a respective height dimension;
a first liquid dielectric material of relatively higher dielectric constant present up to a variable height in the hollow space, and the variable height being in the electric field of the capacitor; and
a second liquid dielectric material of relatively lower dielectric constant and of lesser density than the first liquid located in the hollow space above the first liquid.

Abstract
An electric capacitor of variable capacitance, including a dielectric body comprised of densely sintered ceramic material, including a hollow space extending longitudinally through the tubular ceramic body for containing dielectric liquid. First and second dielectric liquids of different dielectric constants and densities are contained in the hollow space, and an adjusting cylinder connected to the hollow space adjusts the height levels of the two dielectric liquids in the hollow space for adjusting the capacitance of the capacitor. The hollow space is either longitudinal channels through the tubular body or is a radial space between two concentric tubular bodies which together define the dielectric body. The metal layers of the capacitor plates are respectively on the inside and the outside of the dielectric body.
