Hairdryer-ionizing device assembly including a box-like body for holding a suction part, a fan, a driving motor, a heater, an air flow outlet part, an electric switch assembly and an ion emitting device comprising a high voltage generator, from AC to DC, which is electrically coupled to an electrode, and being characterized in that the high voltage generator device is arranged at an intermediate region between the suction part and the air flow outlet part.

The invention is an optical sensor useful for the detection of ionizing radiation emitted from an analyte in a fluid. The sensor is composed of a permeable scintillator having a high surface area to scintillator volume ratio and an optical waveguide located in working relation to the scintillator to collect light photons generated in response to an ionizing radiation source. The sensor is especially useful for biomedical applications. Increased sensitivity allows for miniaturization and implanta...

A device for humidifying and ionizing air includes a first chamber for humidifying the air, a second chamber, which is separate from the first chamber, for ionizing the air, and means for aspirating and expelling the air through the two chambers, keeping the streams of ionized air and of water vapor separate.

An air ionizing ring that provides a flow of ionized gas, comprising a housing having an inlet side and an inlet opening, and a cap that releasably attaches to the inlet side of the housing. When a supply of pressurized gas comes between the housing and the cap, the cap is partially released and the gas flows through the inlet opening. The gas flows sufficiently near a plurality of electrode mounted to the housing and electrically connected to a high voltage power source. Ionization occurs and t...

An imaging device for ionizing radiation, X-rays, gamma rays, or neutrons comprises in succession: a scintillator for transposing the ionizing radiation into electromagnetic radiation (.nu.) in the ultraviolet spectrum, a gas detector coupled to the scintillator and designed to respond to the received radiation by forming an avalanche A of electrons that ionize the gas thereby providing intense light that is optically detectable, An imaging system serves to record the image of the electron avala...

An air amplifying blow-off system incorporating an ionizing apparatus includes a converter driven by the compressed air being directed to an air distributor. The converter provides the power source for the ionizing apparatus. In this way, the air distributor and ionizing apparatus can be an easily contained unit. The system may comprise a turbine which is electrically connected to an ionizing apparatus, such as an ionizing bar. Another system may comprise an oscillatory device connected to a pai...

A plasma gun and powder feed system has purge means for removal of all atmospheric or other matter from the powder feeder, the gun, and inner connecting conduits prior to gun operation. Accurate and automatic flow rate control means are included both for the ionizing gas and the powder feed supply connections to the gun. Oxygen-free purity of powdered materials as received in airtight containers from the manufacturer is thus preserved throughout operation of the plasma-spray system disclosed.

A needle (22) adapted to advance and retract in z directions is accommodated in an ionization chamber (15), whereas an electrolytic solution (L) containing a sample is supplied into the ionization chamber (15) through a supply tube (18). The supply tube (18) is bored with a hole (20) communicating with the inside of the ionization chamber (15). While a predetermined voltage is applied between the supply tube (18) and the needle (22), the tip of the needle (22) is caused to come close to but not ...

An ionizing radiation source comprising a molded and hardened composition based on a phenol-formaldehyde resin and a radioactive material molecularly or ionically dispersed in the resin.

An improved electrostatic ionizing system for use in connection with a spray gun, having a conductive needle positioned near the center of the spray gun spray pattern, the needle having a diameter of less than about 250 micrometers and a needle tip sharpened to have a radius of curvature of less than about 50 micrometers, and a second electrode spaced approximately one centimeter from the needle.
