  • Patent number: 10556192
    Abstract: A supercritical extractor system may include extractor chambers coupled to a supercritical fluid pump and configured to receive a matrix for an extraction process and a supercritical fluid from the supercritical fluid pump, and evaporator chambers coupled to the extractor chambers and configured to output an extractant from the matrix. Each evaporator chamber may include a body defining a cavity, a cone within the cavity, and arms coupled between an inner surface of the body and the cone. The supercritical extractor system may include a condenser coupled between the evaporator chambers and the supercritical fluid reservoir, and a controller coupled to the supercritical fluid pump, the extractor chambers, and the evaporator chambers and configured to monitor a characteristic during the extraction process.

  • Patent number: 9281908
    Abstract: Various embodiments of the present invention provide systems and methods for estimating signal and noise powers in a received signal set. For example, one embodiment of the present invention provides a method for determining signal power and noise power. The method uses a storage medium that includes a Na×Nw data pattern. The Na×Nw data pattern includes Na bits repeated Nw times. Both Na and Nw are each greater than one. The methods further include performing an initial read of the Na×Nw data pattern, which is stored to a first register.

  • Patent number: 4589307
    Abstract: A new improved push button reversible ratchet wrench completely operable by one hand having the push button improvement operably attached to a double-ended pivotal pawl engaging the ratchet wheel having the square shaped stud adapted to receive a socket. The improvement includes a cam connected at one end to the push button located transversely through the shank of the wrench mid-section. The other end of the cam is pivotally attached to an extension control rod which in turn attaches to the double-ended pawl which engages the ratchet wheel. The push button is operated simultaneously with grasping of the handle of the reversible wrench by the operator whereby manipulation of one hand, the direction in which the wrench will ratchet may be selected, or reversed or central neutral position where the pawl does not engage the ratchet wheel, may be chosen in accordance with the needs of the mechanic.

  • Patent number: 4445404
    Abstract: A new improved reversible ratchet wrench completely operable by one hand having the improvement operably attached to one side of the double-ended pivotable pawl engaging the ratchet wheel attached to the square shaped stud adapted to receive a socket, the improvement comprising an extension rod slidably situated along the mid-section of the reversible wrench pivotally connected at one end to the double-ended pawl, the extension rod other end terminating in a thumb control button, said thumb control button operable simultaneously with the operator's hand grasping the handle of the reversible wrench. By manipulation of one hand, the direction in which the wrench will ratchet in may be selected or reversed, or a central neutral position where the pawl does not engage the ratchet wheel may be chosen whereupon the ratchet wrench is completely free of engagement of the socket.
