Electro-expulsive separation system

An electro-expulsive system has one or more overlapped conductors, each comprising a flexible ribbon conductor, which is folded back on itself. The conductors are embedded in an elastomeric material. Large current pulses are fed to the conductors from power storage units. As a result of the antiparallel currents, the opposed segments of a conductor are forcefully separated and the elastomeric material is distended. Voids in the elastomer aid the separation of the conductor segments. The distention is almost instantaneous when a current pulse reaches the conductor and the distention tends to remove any solid body on the surface of the elastomeric material.

Electromagnetic Repulsive Deicer for Aircraft

Scheme for removing ice from airfoils in flight adds little weight and demands relatively small amount of energy. Employing electromagnetic repulsion of conductors embedded in rubber covering on airfoil, scheme breaks up layer of ice by snapping it in manner of snapping rug to remove dust. Layer of elastomer conforms to shape of airfoil in relaxed state. When carrying large electrical currents, conductive ribbons in elastomer repel each other, creating ridged surface on airfoil. Sheet of ice on airfoil broken up in sudden transition from relaxed state to energized state.

EKG and ultrasonoscope display

A system is disclosed which permits simultaneous display of an EKG waveform in real time in conjunction with a two-dimensional cross-sectional image of the heart, so that the EKG waveform can be directly compared with dimensional changes in the heart. The apparatus of the invention includes an ultrasonoscope for producing a C-scan cross-sectional image of the heart. An EKG monitor circuit along with EKG logic circuitry is combined with the ultrasonoscope circuitry to produce on the same oscilloscope screen a continuous vertical trace showing the EKG waveform simultaneously with the heart image. The logic circuitry controls the oscilloscope display such that the display of both heart and EKG waveforms occurs on a real time basis.
