  • Patent number: 11121504
    Abstract: A circuit board separation mechanism may include a separation block positioned within a separation block cut-out of a heatsink. The heatsink may be positioned between a first circuit board including a first component of at least one connector and a second circuit board including a second component of the at least one connector. The circuit board separation mechanism may include a set screw inserted in the separation block. A portion of the set screw may be configured to engage a surface of the heatsink. The separation block may be configured to lift against a surface of the first circuit board when the set screw is rotated. The first component of the at least one connector and the second component of the at least one connector may be configured to separate when the set screw is rotated and the separation block lifts against the surface of the first circuit board.

  • Patent number: 6422734
    Abstract: A static foam generating apparatus including a pipe having an inner diameter, an axis, an input end, and an output end is disclosed. A plurality of perforated discs are disposed in the pipe, the discs positioned parallel to each other and perpendicular to the pipe axis. A plurality of spacer rings are disposed within the pipe, a spacer ring separating each perforated disc from each adjacent perforated disc. Additionally, a method for generating foam including the steps of providing a static foam generating apparatus including a pipe having an inner diameter, an axis, an input end, and an output end, supplying feed water to the pipe, supplying surfactant to the pipe, and supplying air to the pipe is disclosed.

  • Patent number: 4109796
    Abstract: Rod and reel storage apparatus, designed for temporary or permanent storage of fishing rod and reels, which includes a pair of holders, each holder having a mounting bracket, an upwardly extending arm rotatably and removably attached to the bracket, and a loop assembly attached to the top of the arm, the loop assembly including at least one loop having an obliquely located slot at its uppermost end; the loop adapted to receive a fishing rod at a downwardly oblique angle and adapted to prevent removal of the rod at an angle upwardly parallel to the loop axis. The apparatus may also contain a hinge, substantially in the center of the arm for lateral movement of upper part of the arm and the attached loop assembly. The apparatus may also contain means for rotating the loop assembly. A coating of a resilient plastic material on the loop assembly for protecting the rods and reels from abrasion is also provided.
