Abstract:
A drill pipe screen transporter device rotatably couples a drill pipe screen to a transporter for its insertion and/or extraction into and out of a derrick assembly. A first plate assembly has a first base plate; and first and second spacer plates have arcuate notches for engaging the transporter. U-shaped bolts secure the first plate assembly to the transporter. A second plate assembly rotatably connected to the first plate assembly, has an aperture for supporting the screen. A collar assembly, spacer collar and pivot pin rotatably attach the second base plate to the first base plate for rotation of the screen relative to the transporter. A swivel stopper engages the first base plate of the first plate assembly when the second plate assembly is rotated a predetermined amount. A counterweight located opposite to the swivel stopper returns the second plate assembly to its initial horizontal positioning.
Abstract:
A method for translating a decorative surface of an acoustic substrate to an edge of the finished acoustical product is provided. A portion of an acoustical substrate having a decorative surface on a first side is compressed to form a void having at least one adjacent region of compressed material having an increased density. The acoustical substrate is then manipulated to close the void and place at least a portion of the decorative surface on a side of the substrate. The manipulation of the acoustical substrate also places the region of compressed material at the edges of the acoustical substrate, thereby reinforcing the edges of the acoustical product. A decorative non-woven acoustic panel that has at least one peripheral edge with a density greater than the density of the main body is also provided.
Abstract:
A method of forming a box-like acoustical substrate is provided. Portions of an acoustical substrate having a decorative surface are compressed to form a flange, a first compressed region, a second compressed region, and a third compressed region. First, second, central, and third uncompressed regions are positioned respectively adjacent to the compressed regions. A left first surface and a right first surface of the acoustical substrate may be folded toward the back surface of the substrate until the second compressed region and the third compressed regions are flush with the central uncompressed region. An outer portion of the left surface may then be folded towards the back surface until the flange is flush with the right edge. The acoustical product may be used as an acoustical trap or duct. When the acoustical product is utilized as a duct, an air impermeable sheet may be positioned on the external surface.
Abstract:
A method is provided for securing a polymer blanket to a mechanical device. The method includes positioning the polymer blanket against a polymer surface of the mechanical device and ultrasonically joining the polymer blanket to that surface. The invention also relates to a mechanical device including a mechanical component and a polymer insulator ultrasonically joined to a polymer wall of the mechanical device and at least partially enclosing the mechanical component.
Abstract:
A liner/insulator include including at least two individual layers of wet processed mat wherein the layers including thermoplastic polymer staple fibers and thermoplastic bicomponent fibers. The layers are bonded together by heat and pressure to provide “tunable” acoustical and thermal properties.
