  • Patent number: 11714032
    Abstract: Vacuum systems for epoxy mounting of material samples are disclosed. In some examples, a vacuum system may be a castable and/or cold mounting vacuum system that facilitates mounting and/or encapsulation of material samples in epoxy resin under low, vacuum, and/or near vacuum pressure. In some examples, the vacuum system may comprise a flow control device configured to control epoxy flow through a dispensing tube that connects to a hollow vacuum chamber. In some examples, the vacuum chamber may have an opening encircled by a rim sandwiched between upper and lower portions of a sealing ring. A movable lid may be configured to press down on the upper portion of the sealing ring when in a closed position, so as to seal the opening.

  • Patent number: 7493684
    Abstract: Aircraft loading apparatus includes a frame removably attachable to an aircraft (e.g., a helicopter). The frame is constructed for assembly and disassembly in a transitional position and includes a pair of raising and lowering mechanisms. The mechanisms include a pair of belts with free ends attachable to form a sling and connected for simultaneous extension or retraction of equal lengths of each belt. In operation, the frame is attached to the aircraft adjacent an area at which an article (e.g. an auxiliary fuel tank) is to be connected. The article is positioned under the frame and the belts are extended to form a sling around the article. The mechanisms are activated to simultaneously retract equal lengths of each belt to raise the article into a connecting position, the article is connected, and the frame is disassembled into a removable configuration and removed from the aircraft.

  • Publication number: 20060130425
    Abstract: A bracket for reinforcing a wooden joist including a body having a central portion with a base wall. An upper portion is integrally formed with the central portion and has a first wall secured to and extending forwardly from the top of the base wall and a second wall secured to and extending from the front of the first wall. A notch in the top of the base wall extends upwardly through the first and second walls. A lower portion is integrally formed with the central portion and has a third wall secured to and extending at right angles from the bottom of the base wall and a fourth wall secured to and extending at right angles from the third wall. A brace is rigidly affixed to the base wall beneath the notch.

  • Patent number: 5770131
    Abstract: A process and apparatus for applying an oscillating force to a molten material. The apparatus includes a barrel in communication with a hopper for receiving a flow of moldable material. A screw conveyor is rotatable and axially reciprocatable within the barrel. At least one conveyor flight is formed on the screw conveyor for conveying and compressing the moldable material. Rotation and reciprocation of the screw conveyor forces the material to flow out of the barrel and along a conduit in a mold assembly. The conduit communicates with a mold cavity. A controller controls the rotation and reciprocation of the screw conveyor. The controller reciprocates the screw conveyor toward and away from the mold during filling of the mold cavity inducing a shearing of the material. Each reciprocation of the screw conveyor translates the screw conveyor closer toward the mold cavity. A method is also disclosed which includes dispensing a moldable material into an barrel.
