Abstract: A portable microwave leakage detector comprises a dipole antenna and a hot carrier diode connected in parallel with a light emitting diode, the circuit incorporating minimum solder joints and affording maximum sensitivity without moving parts such that the detector circuit does not decay with time. The dipole antenna is oriented diagonally in a detector case so that the user of the detector automatically presents the antenna to the radiating microwave field (or leakage field) at a maximum receiving attitude with respect to the field. The detector can be utilized to determine whether a microwave oven or any other device is leaking radiation beyond limits imposed by the Food and Drug Administration.

Abstract: A method for generating hydrogen bubbles electrolytically in the lower reaches of a body of water which is normally highly saturated with hydrogen; controlling the bubble size of the hydrogen bubbles within a range of from 100 to 600 microns so the hydrogen bubbles function as a vehicle to raise the oxygen deficient water to the surface, but the hydrogen bubbles substantially remain in the water near the surface of the body of water, moving along the surface thereof and move outwardly in a path therealong exposing the water so carried to natural aeration and sunlight; the range of the bubbles size being such as not to adhere to solid materials and carry them to the water surface to eliminate turbidity and the formation of floc.

Abstract: An atomizing system including an improved nozzle assembly in which one or more fluids are mixed and dispersed as droplets from a conical bore controlled by means for adjusting the size of a dispersal orifice in conjunction with means for automatically operating the improved nozzle assembly from a pressure source which simultaneously supplies a pressurized gas and liquid to the valve assembly.
