A brake disc, also referred to as a rotor, for a disc brake has the function of interacting with a brake lining as a friction partner in the disc brake. The brake disc is formed at least in part of a material having a molybdenum content of ?50 wt. %.

A loosefill insulation installation has an insulation space, and insulation material in the insulation space. The loosefill insulation material is made from fiberglass fibers. A thermal resistance (R) per inch of installed loosefill insulation material is between 3.1 and 3.9 R per inch. The average density of the installed loosefill insulation material is between 0.6 and 1.0 pounds per cubic foot.

An automated drywalling system network that including one or more automated drywalling systems that each has a robotic arm. The automated drywalling system network can also include a computational planner that generates instructions for the one or more automated drywalling systems to perform two or more drywalling tasks associated with a target wall assembly. The two or more drywalling tasks can include a hanging task that includes hanging pieces of drywall on studs of the target wall assembly; a mudding task that includes applying joint compound to pieces of drywall hung on studs of the target wall assembly; a sanding task that includes sanding joint compound applied to the pieces of drywall hung on studs of the target wall assembly; and a painting task that includes painting sanded the joint compound applied to the pieces of drywall hung on studs of the target wall assembly.

A method for coating a support with a lightweight insulating shotcrete, includes preparing the shotcrete by mixing, in predetermined proportions, at least a fibrous aggregate, a binder and water; pouring the prepared shotcrete in a tank; having at least one outlet; continuously moving the wet shotcrete in the tank until it reaches the or each outlet; sucking the wet shotcrete along a feeding pipe linking the outlet of the tank to a spraying gun, with a Venturi hose fed with pressurized air, included in the spraying gun; spraying the sucked shotcrete on the support with the spraying gun.

A robotic vehicle, in particular for spraying insulation material, comprises a chassis (110), at least two driven wheels (122) having a common axis of rotation, and a wheel connecting member (151) which connects the two wheels (122). The wheel connecting member (151) is connected to the chassis by a pivotal connection which allows the wheel connecting member to pivot with respect to the chassis about a pivoting axis transverse to the common axis of rotation of the wheels. The wheel connecting member (151) may be removably mounted to the chassis (110).

A truck-mounted cargo box houses a commercial-grade system for blowing loosefill insulation material in bags through a hose, without first removing insulation from the bags. The cargo box and system include bag feeding means, and a chute having an inlet end positioned in an end wall of the cargo box mounted on the truck. Also included is a material processing unit in the form of a wood-chipper style or other industrial and/or commercial grade shredder, for together shredding the bags and the insulation material, without first removing the insulation material from the bags, and conditioning them both, as a composite material, to be fed into a fluid stream through the hose. There is also disclosed a kit for retrofitting a cargo box, and a related method.

There is disclosed a method of retro-fitting an external insulation system to a building, and a retro-fit external insulation system for a building. One disclosed method comprising the steps of: mounting a plurality of support elements (16) to an existing external surface (14) of a wall (12) of a building (10); providing a plurality of surface panels (22), each of which comprises an internal wall-facing surface (36) and an external surface (38); arranging the surface panels so that they cover at least a substantial part of the existing external surface of the wall; mounting each surface panel to one or more of the support elements, so that cavities (40) are defined between the internal wall-facing surfaces of the panels and the existing external surface of the wall; and supplying flowable insulation material (42) into the cavities; in which the step of mounting the support elements to the external surface comprises positioning at least one adjustable one-piece spacer (108) between each support element and the surface, the spacer comprising a first end (112) which abuts the surface and a second end (114) which abuts the support element, and adjusting the spacer to vary a space (110) between the support element and the surface.

The present disclosure relates generally to methods, devices and systems for insulation, e.g., of cavities associated with walls, ceilings, floors and other building structures, with foam insulation. In one aspect, the disclosure provides a method for providing a cavity of a building with a predetermined amount of foam insulation. The method includes actuating a valve to begin dispensing foam insulation into the cavity, the actuation being performed by a user, the actuation by the user fixing a start time and/or a zero volume of a time and/or volume meter; then, dispensing the foam insulation from the insulation dispenser into the cavity as the time and/or volume meter counts time and/or volume dispensed; then when a predetermined time after the start time elapses or a predetermined volume of the foam insulation beyond the zero volume is dispensed as measured by the time and/or volume meter, actuating the valve to stop dispensing the foam insulation into the cavity.

A method of manufacturing building panels includes assembling a frame of a building panel. The frame defines at least one cavity and at least one injection aperture in fluid communication with the at least one cavity. The method also includes positioning the frame on one of a base and a shelf of a multi-panel consolidation device having a plurality of shelves, with the shelves being in an expanded configuration, and at least substantially enclosing the at least one cavity. The method also includes forcing the shelves of the multi-panel consolidation device into a collapsed configuration, and injecting an expandable polymer through the at least one injection aperture into the at least one cavity. The method further includes forcing the shelves into an expanded configuration after a predetermined period of time selected to permit the expandable polymer to form a foam bonded to the frame.

An automated drywalling system network that includes one or more automated drywalling systems that each has a robotic arm. The automated drywalling system network can also include a computational planner that generates instructions for the one or more automated drywalling systems to perform two or more drywalling tasks associated with a target wall assembly.
