  • Patent number: 10668614
    Abstract: A hand-held power tool is provided that includes a housing, a motive source, a front endbell, an output shaft, a front housing, and a gear set assembly. The output shaft protrudes from an output end at the front endbell of the housing. The output shaft is also functionally coupled to the motive source such that the output shaft rotates in response to activation of the motive source when the motive source is supplied with power. The gear set assembly is located in an interior space of the front housing, and is configured to transfer rotation from the motive source to an output spindle. The gear set assembly also includes a ring gear that surrounds a portion of the output shaft and abuts the front endbell of the housing. A set of piloting features is provided that is configured to prevent movement of the ring gear relative to the motive source and the front housing, or the front housing relative to the housing.

  • Patent number: 10623118
    Abstract: The system and method for adaptively obtaining coefficients of an inverse model for both equalization and pre-distortion for a multi-channel and reconfigurable RF system. The system preforms real-time learning and adaption and does not require training sets. In some cases, the system learns new coefficients across time and transient changes in performance.

  • Patent number: 10557740
    Abstract: A bulk material storage bin has an upright wall supporting a plurality of vertically spaced indicators providing a person with visual information regarding the level of the bulk material in the bin. The indicators have bright color and dark color surfaces that are selectively displayed to provide a person with information of the level of bulk material in the bin. An actuator located in the bin cooperates with a motion transmission apparatus to move visual members to an ON position displaying the bright color when the bulk material engages the actuator and to an OFF position displaying the dark color when the actuator is free of bulk material. The motion transmission apparatus includes a rod movably retained on an O-ring held on a mount device secured to the side wall of the bin. A yoke supporting an endless flexible member mounted on the rod is connected to the visual members whereby movement of the rod moves the visual members between the ON and OFF positions.

  • Patent number: 10408659
    Abstract: A material storage bin has an upright wall supporting a plurality of vertically spaced indicators providing a person with visual information regarding the level of the material in the bin. The indicators have contrasting visual colors as bright yellow and dark black surfaces that are selectively displayed to provide a person with information of the level of material in the bin. An actuator located in the bin cooperates with a motion transmission apparatus to move visual members to an ON position displaying the bright color when the material engages the actuator and to an OFF position when the actuator is free of material in the bin.

  • Patent number: 10309177
    Abstract: A system and method for collecting a core sample. The system includes an outer cylindrical tube, a drive head, a drive shoe, a cooling chamber housed inside the outer cylindrical tube, insulation, a core sample liner, an inlet tube, and outlet tube. The drive shoe further comprises a first, second, and third step, the first step configured to receive the insulation, the second step configured to receive the cooling chamber, the third step configured to receive the core sample liner, wherein the first step has a diameter larger than the second step and the second step has a diameter larger than the third step. The method includes drilling a hole in the ground with a drilling tool, enclosing a core sample by a core sample liner, freezing the core sample via a cooling liquid, retrieving the drilling tool at a surface of the ground, and removing the core sample encased in the core sample liner from the cooling chamber.

  • Publication number: 20190151871
    Abstract: A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.

  • Patent number: 6143172
    Abstract: A plurality of water- and oil-porous sacks are partially filled with a number of generally toroidal bodies of a polymer material that entraps oil and including mesh fragments scattered throughout the bodies. Each sack is sewn with a perimeter stiffening ring, to retain a flat profile, and has a netting that closes to help inhibit outflow of the oil when the sack is retrieved. When deployed from ship or by air onto a spill, the sacks spread into a pancake shape and the polymer matter forms a single layer that retains the oil. The inventive sacks will float indefinitely without releasing the oil or allowing it to emulsify, so the oil can remain in place until collection efforts are feasible. The sacks can be burned in situ, or standard fishing boats or specialized collection boats can be used to retrieve the sacks, and the collected material can be burned to capture the energy content of the oil or processed to separate the oil from the polymer.

  • Patent number: 6067927
    Abstract: An indicator providing visual information of the level of bulk material in a bin has rotatable visual members with bright and dark colored surfaces covered with a transparent lens. A actuator located within the bin is operatively coupled to the visual members to turn the visual member to an ON position exposing the bright colored surface to a person when bulk material engages the actuator and to an OFF position exposing the dark colored surface to a person when the actuator is free of bulk material whereby the person can determine the level of the bulk material in the bin. The visual members are also provided with a device that triggers a sensor that activates a remote indicator providing data as to the level of bulk material in the bin.

  • Patent number: 5629377
    Abstract: A water-absorbent resin particles that exhibits a centrifuged absorption capacity of 26 g/g or greater, an absorption under load of 24 g/g or greater at 0.6 psi load. Other aspects of the invention are processes for the preparation of such water-absorbent resin particles which comprise the inclusion of chlorine or bromine containing oxidizing agent followed by the heat-treatment to produce particles with superior centrifuged absorption capacity in combination with high absorption under load at high load, and acceptable levels of residuals. These water-absorbent resin particles provide superior performance when incorporated into absorbent structures.
