Abstract: An apparatus for obtaining samples from a structure includes a support member, at least one stabilizing member, and at least one moveable member. The stabilizing member has a first portion coupled to the support member and a second portion configured to engage with the structure to restrict relative movement between the support member and the structure. The stabilizing member is radially expandable from a first configuration where the second portion does not engage with a surface of the structure to a second configuration where the second portion engages with the surface of the structure.

Abstract: A lightweight, flatbed semi-trailer vehicle constructed substantially entirely of lightweight, high-strength structural members and capable of being utilized in conjunction with a truck tractor. The vehicle does not require flooring or decking and comprises at least two longitudinal spaced apart support members, and a plurality of transverse support members bolted to the upper surfaces of the longitudinal support members for use as a lowermost tier of dunnage. A stress plate provides structural rigidity to the design and serves as a second means of interconnecting the longitudinal support members. The vehicle also is equipped with unique fluid suspension means for absorbing and dampening road vibrations and offsetting any adverse effects caused by the elimination of a lower tier of dunnage.

Abstract: This invention is a compact, precise, and relatively simple device for use in determining the average rate of flow of a liquid through a conduit. The liquid may be turbulent and contain bubbles of gas. In a preferred embodiment, the flowmeter includes an electrical circuit and a flow vessel which is connected as a segment of the conduit conveying the liquid. The vessel is provided with a valved outlet and is partitioned by a vertical baffle into coaxial chambers whose upper regions are vented to permit the escape of gas. The inner chamber receives turbulent downflowing liquid from the conduit and is sized to operate at a lower pressure than the conduit, thus promoting evolution of gas from the liquid. Lower zones of the two chambers are interconnected so that the downflowing liquid establishes liquid levels in both chambers.
