  • Patent number: 8468822
    Abstract: A process and electromechanical system for conditioning the incoming air or air/fuel charge for an internal combustion engine to result in an optimally prepared charge in terms of temperature of the charge and fuel dispersion in the charge. The process includes compressing intake air, bifurcating the compressed intake air stream to provide for heating one branch of the stream while not further purposely heating the other. The process further includes controlling the proportion between the bifurcated stream portions to provide for a desired set point temperature of the combined stream. The process includes selection of the set point temperature such that the temperature of the air is in the vicinity of the fuel self ignition temperature at the end of the compression stroke. Primary components include one or more of an air compressor, heat exchanger, bypass duct, proportioning valve, airflow director, and attendant control system including sensors, processor, and actuator(s).

  • Patent number: 5261538
    Abstract: The present invention comprises a method for measuring the amount, i.e., mass, of a volatile liquid which comprises passing the mass over a heat loss measuring device, calculating the amount of heat loss accompanying the vaporization of the mass and correlating the heat loss to measurement of heat loss of known liquid aerosol mass made with the same device.

  • Patent number: 5239993
    Abstract: A breath actuated dry powder medicament inhalator has a primary air passageway therethrough defining a venturi in the medial portion thereof. A secondary air passageway is provided which includes a compound deaggregating swirl chamber and is fluidly connected to the venturi of the primary air passageway. A dry powder compound storage chamber and cooperatively associated metering plate act to introduce a predetermined amount of compound into the swirl chamber upon actuation of the metering plate. The primary air passageway is configured within the inhalator apparatus so as to create an optimized air flow trajectory through the mouth of the user to minimize dry powder compound impingement upon the outside radius of the throat.

  • Patent number: 5161524
    Abstract: A breath actuated inhalator having a primary and a secondary air flow conduit wherein regulator means are provided in the secondary air flow conduit to planate maximum air flow velocity through the inhaler. By optimizing air flow and velocity rate, the breath actuated inhalator prevents problems associated with excessive inhalation velocity such as dry powder drug compound impingement upon the outside radius of the throat.

  • Patent number: 5040353
    Abstract: A pneumatic apparatus for withdrawing and recycling goods from defective blister packages on a blister packaging machine comprising a housing which is positioned on the blister packaging machine between the detection station and the sealing station and having a plurality of transversely spaced-apart open chambers in the bottom thereof. A plurality of air valves are connected to a high air pressure source and to the blister package machine detection station, and each air valve corresponds to a respective chamber in the bottom of the housing. A plurality of air venturi nozzles are provided wherein each air venturi nozzle is fluidly connected at its air pressure input end to a corresponding air valve and chamber.

  • Patent number: 4327604
    Abstract: A continuously variable ratio power transmission for a motor vehicle consists of two planetary gear sets and overrunning clutches to continuously modify said transmission reduction ratio as a function of the output shaft load conditions. A continuously variable ratio power transmission for a motor vehicle wherein one planetary gear set divides the input shaft torque and speed between two driven members of said planetary gear set which comprise the driving members of a second planetary gear set whose direction of angular motion is determined by overrunning clutches to limit the maximum reduction ratio range possible. A transmission of the aforementioned configuration allows a continuous change of reduction ratio as the magnitude of the torque delivered to the input shaft approaches the magnitude of the torque demanded by the output shaft load. The continuous change of reduction ratio allows the input shaft, and hence, the engine, to operate at nearly constant load conditions.
