Abstract:
An electronic cigarette is provided. The electronic cigarette includes a casing having two chambers located sequentially within the casing. A battery and a fluid are located in the casing. A sealing element forms a partition between the chambers. A tube element is located in the second chamber, providing an air passage between the two chambers. Also included is a fiber element that transfers fluid from a fluid containing member to a heating assembly.

Abstract:
A battery charging circuit for use in aircraft wherein a voltage-regulated alternator is employed to maintain a nickel cadmium battery charged. A temperature-dependent resistance element thermally coupled to the battery provides a reference voltage against which battery terminal voltage is compared. When the terminal voltage falls below the reference voltage application of sensing voltage to the alternator voltage regulator is interrupted, causing full charging current to be applied to the battery. When the terminal voltage exceeds the reference voltage, sensing voltage is reapplied to reduce charging current. The alternator switches between maximum and minimum charging efforts to maintain a voltage level dictated by the battery temperature.
Abstract:
A hot water generator capable of producing a maximum rate of water temperature increase without generation of vapors including a heat exchanger in the form of an annularly shaped helical coil through which the water to be heated is pumped and which is connected to a piping system including a load and a combustor for rapidly providing increased combustion which is controlled in response to the temperature of the water at the outlet of the coil so that the heater can produce a maximum rate of water temperature rise without causing boiling and generating vapors in the coil. The method concerns the shock testing of piping components by producing nearly theoretical maximum heat flux rate very quickly.
Abstract:
A speed detector for producing from the output of an axlemounted transducer an analog output signal indicative of the speed of a moving vehicle. A signal processing circuit responsive to the output of the transducer generates a square-wave control signal which is utilized to control the recurrent charging and discharging of an error integrating capacitor. The rate of discharge of the capacitor is such that an error voltage is developed across the capacitor indicative of the vehicle speed error, and an FET switch controlled by the square-wave periodically applies this error as a pulse to a storage integrator. By varying the discharge rate of the capacitor in accordance with the voltage developed in the storage integrator, an analog output signal indicative of vehicle speed is developed. By controlling the conduction time of the FET switch, the effectiveness of the error on the analog output signal is proportioned to the absolute speed error of the vehicle.
