Title: Condensation-evaporator nanoparticle charger

Abstract

A particle charging method and apparatus are provided. An ion source is applied to a particle laden flow. The flow is introduced into a container in a laminar manner. The container has at least a first section, a second section and a third section. The first section includes wetted walls at a first temperature. A second section adjacent to the first section has wetted walls at a second temperature T2 greater than the first temperature T1. A third section adjacent to the second section has dry walls provided at a temperature T3 equal to or greater than T2. Additional water removal and temperature conditioning sections may be provided.

  • An improved battery charger of the type having a housing with a source of electrical energy therein suitable for recharging units capable of being electrically recharged is described. The housing includes a plurality of cavities each arranged to accommodate a unit to be recharged, and each cavity has electrical contacts which are positioned to contact the terminals of the unit inserted into each cavity for delivering electrical energy to that unit. The improvement comprises a switch in each cavity which is activatable by insertion of the unit therein, the switch being separate from and free from direct contact with themore » electrical contacts, but electrically connected to the energy source which, in turn, energizes the electrical contacts for recharging the unit upon activation of the switch. A battery pack unit capable of being recharged including a housing with a first pair of electrically conductive metallic strips on the outside of a side portion thereof, and a second pair of metallic strips on the outside of a top portion of the housing. A plurality of batteries is in the housing, the batteries being electrically connected to each other and to both pairs of the metallic strips. One of the strips in each pair is a negative terminal and the other strip in each pair is a positive terminal for the pack unit.« less
  • A battery charger is described, comprising: a source of electrical power for providing signals of cyclically varying amplitude; a switching device that is triggerable for coupling at least a portion of the varying amplitude signals to a battery to be charged; a trigger circuit for providing a trigger signal to the switching device; a logical ANDing circuit having at least two inputs for receiving electrical signals corresponding to criteria that must be satisfied before the switching device can be triggered, said logical ANDing circuit having an output for enabling the trigger circuit so that when the trigger criteria is satisfied,more » the switching device is triggered; and a trigger level detector coupled to one input of said logical ANDing circuit and responsive to a predetermined amplitude of the varying amplitude signal for enabling said ANDing circuit when the varying amplitude signal is below a predefined trigger level.« less
  • A normally open polarity sensing circuit is interposed between the charging current output of a battery charger and battery terminal clamps connected with a rechargeable storage battery. Normally open reed switches, closed by battery positive terminal potential, gates silicon controlled recitifiers for battery charging current flow according to the polarity of the battery.
  • This invention is a novel pocket-type radiation dosimeter comprising an electrometric radiation dosimeter and a charging circuit therefor. The instrument is especially designed to be amenable to mass production, to have a long shelf life, and to be compact, lightweight, and usable by the layman. The dosimeter proper may be of conventional design. The charging circuit includes a shake-type electrostatic generator, a voltage doubler for integrating generator output voltages of one polarity, and a switch operated by an external permanent magnet.
  • A battery charger device characterized by a pair of cigarette lighter plugs having their negative contacts coupled together by a conductor and having their positive contacts coupled together by a self-resetting circuit breaker. In use, one of the plugs is inserted into the cigarette lighter socket of a car having a discharged battery and the other plug is inserted into the cigarette lighter socket of another car having a good battery. If the discharged battery starts to draw current that is greater than a predetermined level the current flow is regulated by a rapid cycling on and off of themore » circuit breaker. When the current drawn by the discharged battery is less than the predetermined level the circuit breaker conducts current between the two batteries with only insignificant IR loss.« less
