UNITED STATES GYPSUM COMPANY

A work vehicle includes an operator seat and a seat sensor configured to provide a first signal in response to presence of an operator seated in the operator seat. A pedestrian detection system includes an electronic controller operatively coupled with one or more sensors. The pedestrian detection system is configured to detect presence of a pedestrian in proximity to the work vehicle. A controllable switch device operatively coupled with the seat sensor and the pedestrian detection system. The controllable switch device is configured to provide a second signal to activate the pedestrian detection system in response to the first signal provided by the seat sensor.

A cement-based acoustic isolator for use in a composite flooring system which includes a Cross Laminated Timber (CLT) subfloor, a metal inverted track attached to a top surface of the cement-based acoustic isolator, and an upper flooring attached to a top surface of the metal inverted track, includes a plurality of structural panel layers stacked upon one another; and an adhesive which secures the plurality of structural panel layers to one another. The adhesive also secures the plurality of structural panel layers to the metal inverted track and the CLT subfloor of the composite flooring system.

Sprayable joint compound compositions, building construction assemblies and methods, including methods for finishing joint seams and methods for installing interior walls and ceilings, the sprayable joint compound compositions having a thixotropic property and the sprayable joint compound compositions comprising a combination of a thixotropic rheological modifier, a polyacrylic dispersant and a hydrophobic lightweight filler.

An apparatus for determining durability of a wallboard joint compound composition includes an adhesion release testing machine including a machine base, a vertical mast connected to the base, a load cell connected to the mast, a sled movable on the machine base between a first position and a second position, a display associated with the machine base and connected to the load cell for displaying numerical values of loads applied to the load cell. A probe plate includes a lower surface with a depending probe; an anchor base disposed on an upper surface of the probe plate; and a chain connecting the probe plate to the load cell. A set sample strip of wallboard joint compound composition is secured to an upper surface of the sled and arranged for engagement by the probe as the sled moves on the machine based between the first position and the second position.

A method for assembling a wall system to retrofit an existing panel and frame building assembly for a wall, floor or roof, including providing a sound damping building panel including a dense, fiber-reinforced, structural cementitious panel of fiber-reinforced cement, the dense, fiber-reinforced, structural cementitious panel having a first surface opposed to a second surface, and a layer of acoustic dampening material on the first surface of the dense, fiber-reinforced, structural cementitious panel; attaching the sound damping panel to an existing building panel attached to an existing frame for a wall, floor or roof, the existing building panel having an interior surface facing the frame and an exterior surface opposed to the interior surface. This locates the layer of acoustic dampening material between the exterior surface of the building panel and the first surface of the sound damping panel. A sound damping building panel is also provided.

A building composition, such as a joint compound or texture, including flotation tailings of mined ore as a primary filler, and method of making the building composition. The joint compound may be a drying type joint compound or a setting type joint compound. The joint compound or texture may also include at least one secondary filler. The setting type joint compound may also include calcium sulfate hemihydrate.

Disclosed are product (e.g., board), slurry, and methods relating to an uncooked starch that can be used to enhance strength in one or more gypsum layers in the board. The uncooked starch bas a hot water viscosity of from about 20 BU to about 300 BU according to the HWVA method, and/or a mid-range peak viscosity of from about 120 Brabender Units to about 1000 Brabender Units.

Methods for installation, repair and finishing of interior walls and ceilings by applying a coating of a self-priming joint compound containing at least a first filler having a particle size distribution with a median particle diameter (D50) in the range from about 18 μm to about 65 μm, a second filler having a particle size distribution with a median particle diameter (D50) in the range from about 0.6 μm to about 25 μm, wherein a ratio of the first filler to the second filler is in the range from 1:2 to 1:10 by weight; a polymeric binder; a thickener and a rheology modifier.

A handheld viscosity measurement device is provided and includes a housing including a drive shaft coupled to a motor, and a handle, a spindle attached to the drive shaft, a display device attached to the housing and a battery attached to the housing. In operation, the spindle is inserted in a material while the motor rotates the drive shaft and the spindle, the display device displays a measurement based on the resistance of the material on the spindle.
