Abstract: A fill port cap combination wrench designed to facilitate opening, closing, and properly torqueing most six-inch fill port caps on intermediate bulk containers and mini bulk containers. The fill port cap combination wrench includes a flat annular surface adapted to engage tabs on the fill port cap, and a connecting member having a first side and a second side. A first support structure vertically extends from the first side of the connecting member to the flat annular surface and a second support structure vertically extends from the second side of the connecting member to the flat annular surface. The connecting member further includes an aperture, disposed between the first side and the second side, for engaging the drive of a socket wrench or a torque wrench. A handle is included laterally extending from each support structure for manually turning the fill port cap combination wrench.

Abstract: A universal cap seal for fifty-five gallon drums designed to fit over bung flanges and rims in drums of varying size and varying height. The universal cap seal comprises a body having a flat upper surface and an internal surface. The flat upper surface of the body includes a channel that holds a tamper evident lifting band. The lifting band has a lifting tab that enables the user to remove the cap seal from the flange. A sidewall extends from the flat upper surface. A shield extends downwardly from the sidewall and includes a plurality of individual pivotal segments separated by a plurality of slits. The internal surface of the body includes at least two downwardly extending internal snap elements that frictionally engage an outer portion of the flange.

Abstract: A temperature compensated pair of resonators. The temperature compensated pair of resonators comprises a first resonator configured to resonate at a first frequency and having a first frequency temperature coefficient and a second resonator configured to resonate at a second frequency and having a second frequency temperature coefficient. The second frequency is greater than the first frequency; the second frequency temperature coefficient is less than the first frequency temperature coefficient; and the first and the second resonators are fabricated on a common substrate.

Abstract: An apparatus and method for detecting a target environmental variable (TEV). A first film-bulk acoustic resonator (FBAR) oscillator that includes a first FBAR with a first response to the target environmental variable generates a first frequency. A second film-bulk acoustic resonator (FBAR) oscillator that includes a second FBAR with a second response to the target environmental variable generates a second frequency. A circuit that is coupled to the first FBAR oscillator and the second FBAR oscillator determines the target environmental variable (e.g., changes in the TEV) based on the first frequency and the second frequency.

Abstract: A playground climber comprises one or more equally sized dodecahedron-shaped modules, two or more of which of equal size are joined together along a face of each. The modules are each made up of pieces of pipe of equal length attached together at their ends using a connector, each module having twelve faces and twenty corners, each face having five sides, and each corner being formed by the juncture of three pipes. Each module is a regular dodecahedron with structural members so positioned that a child can reach the members. Also, the majority of the faces of the dodecahedrons are open to permit a child to pass therethrough. The structural members of each face of each dodecahedron are spaced close enough to each other to permit a child to grasp the structural members of a regular pentagon, which forms each face of the dodecahedron, while climbing thereon.
