  • Patent number: 12018493
    Abstract: The present disclosure relates generally to building surface products, for example, suitable for forming a building surface. The present disclosure relates more particularly to a building surface product including a panel having a front surface, a rear surface, and a gypsum body between the front surface and rear surface. A first attachment clip is secured to the rear surface of the panel and includes a first leg extending outward from the rear surface of the panel. A retaining flange is coupled to the first leg and extends over the rear surface in a first direction. The retaining flange includes a slot that is configured to receive a post so as to secure the building surface product to a support structure. A first fastener that penetrates the rear surface of the panel is attached to the first leg so as to secure the attachment clip to the panel.

  • Patent number: 11162884
    Abstract: The present disclosure relates to devices and methods for determining the density of insulation. For example, one aspect of the disclosure is a device that includes a sound generator and one or more sound sensors configured to detect sound that is generated by the sound generator and transmitted through the insulation to the one or more sound sensors. The device also includes a control system configured to cause the sound generator to generate the sound and use the sound detected by the one or more sound sensors to generate output that represents the density of the insulation. Another aspect of the disclosure is a method for using the device to determine the density of insulation.

  • Publication number: 20080028619
    Abstract: A heavy-duty material processing shears includes pivotally connected jaws and a hydraulic cylinder operatively extending between the jaws to open and close the jaws. One of the jaws includes a cutting blade with a substantially convex cutting edge. The cutting blade's surfaces intersect at an acute angle to define the cutting edge. The cutting blade's shape enables it to efficiently pierce and cut through large diameter structures such as conductor pipes. The other jaw includes a substantially concave portion that cradles the work piece. The shears include various features that facilitate subsea or above-water use of the shears to cut portions of a decommissioned oil platform.
