Abstract: A liquid, such as water, is heated by the application of alternating electric current to resonate the molecules of the liquid. In a preferred embodiment, multi-phase alternating current is applied with one phase applied to a pair of capacitive elements inserted into the liquid and the other phase applied to an inductive element inserted in the liquid between the pair of capacitive elements. By applying alternating current to the liquid in such a manner, the liquid is rapidly and efficiently heated.

Abstract: The sensitivity of a balance beam having unequal arms used to detect and measure phenomenon which exert low energy mechanical forces includes a U-shaped beam area having a horizontal slot therein and a pivot post having a vertical slot which registers with the horizontal slot. A fastener, such as screw and wing-nut passes through the slots to releasably fix the pivot post to the fulcrum area in a selected horizontal and vertical position. The selected position is the optimum point of equilibrium of the beam that is determined when the horizontal fulcrum's bottom knife edge passes through center of gravity of the beam. Pivot post has a blade thereon which extends perpendicular to the balance beam and rests on a pair of fulcrum supports. The fulcrum supports are vibrated by a didder device to enhance sensitivity of the balance beam.
