US Patent:

8324762, Dec 4, 2012

Filed:

Nov 23, 2009

Appl. No.:

12/624352

Inventors:

Christian Harvey Keller - Leesburg NJ, US

International Classification:

H02K 7/075

US Classification:

310 20, 310 46

Abstract:

An engine powering device with magnetic components that aid in the operation of piston propelled engines by attaching the device individually to the pistons, causing the pistons to perform the up and down thrusts without the use of fuel combustion thereby mobilizing the engine, eliminating the necessity of fuel and preventing pollution exhausting into the atmosphere. An exemplary system for a magnetically controlled propelled engine that uses exhausted clean air from the engine that flows through an electric generating turbo or turbine to charge the battery to power the engine. Passenger compartment comfort heating is supplied by and electric liquid boiler or liquid heater with a circulation pump. A fuel door mounted universal electrical connector to aid in charging engine battery. This engine has magnetic shielding safety components to protect people and other electronic devices from strong rare earth magnets and electromagnets.

Filed:

Aug 31, 1979

Appl. No.:

6/071704

Inventors:

Christian A. Keller - Baltimore MD

Assignee:

The Johns-Hopkins University - Baltimore MD

International Classification:

G01F 2326

US Classification:

73304C

Abstract:

A generated signal is passed through an elongated signal conveying element positioned preferably perpendicular to the surface of a fluid the level of which is to be measured. The signal is directed from the signal conveying element to a detector element which senses the signal output from the signal conveying element. The signal output detected varies linearly with the depth of immersion of the signal conveying element into the fluid. In one embodiment, the signal conveying element is a capacitive probe comprising two plates or wires, one of which is grounded to the fluid into which the two plates or wires are immersed. Proper selection of accompanying circuitry results in detected signal changes which vary linearly with immersion changes. A second embodiment employs an electromagnetic wave, e. g. light, signal which passes through a light pipe signal conveying element.

International Classification:

G02B 514

US Classification:

250227

Abstract:

A generated signal is passed through an elongated signal conveying element positioned preferably perpendicular to the surface of a fluid the level of which is to be measured. The signal is directed from the signal conveying element to a detector element which senses the signal output from the signal conveying element. The signal output detected in an optical embodiment varies logarithmically with the depth of immersion of the signal conveying element into the fluid. A preferred embodiment employs an electromagnetic wave, e. g. , light, signal which passes through a light pipe signal conveying element. By nearly matching the light pipe index of refraction with that of the fluid, a predetermined precentage of the wave is lost into the fluid each time the light is reflected further along the pipe. The portion of light sensed at the detector, which is located where the unrefracted light exits, is readily converted to an output which varies linearly with the depth the light pipe signal conveying element is immersed into the fluid length.
