Abstract: A laminated construction board comprising a kraft board support backing adhesively bonded to a foam insulating panel is disclosed. Also shown is an improved method for attaching laminated construction boards with fasteners. The fasteners are driven through the foam panel, until the retaining portion thereof engages the support backing, securing it in abutting relationship with an underlying wall substructure. The insulated surface of the board may be covered with various surface finishes, and is especially suited for use with acrylic mortar systems.Also disclosed is a building structure, a method of constructing a building structure, a wall surfacing system, and a method of constructing a wall sheathing, all utilizing construction boards attached to a substructure with staples wherein the crown of the staple engages the support backing of the construction board.

Abstract: A warp sensing apparatus for measuring the displacement or warp in disk-shaped objects such as drum lids and the like. A drum lid or other disk-shaped object is centered on the apparatus and clamped at the axis of rotation of the disk-shaped object. After the disk-shaped object is clamped, a contact probe of a transducer is positioned on the surface of the disk-shaped object to measure bidirectional displacement of the contact probe perpendicular to the surface of the disk-shaped object caused by undulations in the surface of the disk-shaped object. A manual rotating wheel permits the disk-shaped object to be rotated. A meter readout on the transducer displays the magnitude and direction of the contact probe displacement caused by undulations in the disk-shaped object as the disk-shaped object is rotated.

Abstract: Embossed, coated paper is prepared by a process in which a polymeric film is laminated to a paper web, utilizing an extrusion coated resin interlayer therebetween, and a pattern from an engraved chill roll is simultaneously embossed onto the exposed surface of the polymeric film.

Abstract: An improved automatic air pressure relief and check valve assembly which may be used in combination with a swimming pool filter tank or a swimming pool separation tank. The valve assembly includes a normally open lower valve which communicates with the inside of the tank and is responsive to the tank's being full of pressurized water for closing the lower valve. The valve assembly further includes a normally closed upper valve communicating with the lower valve and the outside of the tank, the upper valve being responsive to air being expelled from the tank through the open lower valve, when water is filling the tank, for opening the upper valve to permit the air being expelled to exit through the upper valve. Cooperating with the upper and lower valve of the improved valve assembly is means for precluding both the upper and the lower valves from being simultaneously maintained in their closed conditions.

Abstract: Valve assemblies having a valve seat with a conical surface for causing an included O-ring to roll upon and wedge against the conical surface for closing the port when a spherical valve member is forced against the O-ring.

Abstract: Valve assemblies having valve seats and/or valve members with conical surfaces which cause an included O-ring to roll upon and wedge between the valve member and the seat for reliably closing the valve.

Abstract: An automatic air pressure relief and check valve assembly which may be used in combination with a swimming pool filter or separation tank. The valve assembly includes a normally open lower valve which is responsive to the tank's being full of water for closing the lower valve, and a normally closed upper valve which is responsive to air being expelled from the tank through the normally open lower valve for opening the upper valve during times when water is filling the tank. The upper valve may be selectively opened when air is required to enter the tank so that water may be drained from the tank. Preferred embodiments of the upper and lower valves include valve seats having conical surfaces and respective valve members which cause an included O-ring to roll upon and wedge against its conical seat for reliably closing each valve.

Abstract: A laminated composite sheathing is adapted to provide structural support and resist weakening from weathering by providing a thermally insulating layer of foam bonded on one or both faces to a relatively rigid laminated sheet preferably formed of a fiberboard core adhesively secured between facing sheets of kraft paper bonded together with a resilient polymeric material.

Abstract: A mobile concreting apparatus and method which may be used, in particular, for on-site construction of swimming pools. It includes a vehicle supporting a plurality of containers, each adapted to contain one of the ingredients of concrete. Each container is provided with its own ingredient feeder which feeds the ingredients to a mixing device mounted on the vehicle to create a concrete slurry. The slurry is transferred from the mixing device to the surface to be coated by a structure including a slurry pump, a hose and a nozzle. Each ingredient feeder can be individually varied in the rate at which it feeds its ingredient so that the relative composition of the slurry, and the flow rate of the slurry, can be rapidly and selectively varied on the job site to meet the particular requirements for each job. In addition, feed rate settings which provide a desirable composition and overall feed rate can be noted and reproduced on subsequent occasions when the same composition and feed rate are desired.
