A barrier system for partitioning a space includes panels which interlock with each other to provide a barrier that is fire rated. The interlocking panels are assembled in the barrier in columns using a tongue and groove assembly and a panel lock using a strike and latch supported by the tongue member and groove member, respectively. Each panel includes a peripheral frame (that is shaped to provide the tongue and groove members), opposed steel side faces mounted to the peripheral frame, and an insulation block filling an interior space delimited by the peripheral frame and the opposed steel side faces. The insulation block includes a pair of insulating material layers that sandwich a radiant barrier layer. A floor module supports a bottom edge of the panel and an interface module supports a side/top edge of the panel. The floor/interface modules are configured with telescoping sections and are length trimmable.

A system for enhancing sound provided by at least a first and a second speaker driver symmetrically positioned relative to a first side and a second side of a listener. The system includes a enclosure structure having a first portion relative to the first speaker driver and the first side of the listener, including a material having a sound reflective surface, and positioned between a first area proximate the first speaker driver and a second area proximate the first side of the listener. The enclosure structure also has a second portion relative to the second speaker driver and the second side of the listener, including a material having a sound reflective surface, and positioned between a third area proximate the second speaker driver and a fourth area proximate the second side of the listener.

A system, comprising: a storage workspace including a first framework defined by a series of first uprights, the first uprights supporting a grid of two substantially perpendicular sets of rails; and a plurality of containers for storing objects, wherein the plurality of containers are arranged in stacks, each stack of containers is located underneath a grid space in the workspace; and a grid extension including a continuation of the two substantially perpendicular sets of rails, and wherein the plurality of containers can be moved by one or more load handling devices between the storage workspace and an area beneath the grid extension, wherein the area beneath the grid extension is configured for positioning a roll cage such that containers can be placed or removed from the roll cage.

A dry partition wall system comprising a plurality of wall elements, a floor-side connection element extending over several wall elements, a ceiling-side connection element extending over several wall elements, in which the plurality of wall elements are arranged side by side and are retained on the floor-side connection element and on the ceiling side-connection element and thus jointly form a partition wall, and in which the wall elements are of a multi-layer design.

An inter-tenancy partitioning system installed between floor and ceiling slabs has aligned dual spaced apart ceiling and floor channels formed by channel forming members. Dual panels are supported vertically within the aligned dual ceiling and floor channels Each panel having a width less than that of each channel and the channels are spaced apart to provide a gap between the panels. The panels have a height of greater than 2800 mm and extend through a suspended ceiling to engage the respective channel forming members at the ceiling slab above the suspended ceiling. Outer vertical pieces of the channel forming members of the floor channels have a height that does not extend vertically beyond an upper surface of the adjacent floor covering.

A foldable modular wall system includes a track, one or more stationary wall modules, and one or more foldable wall modules. The foldable wall modules are pivotally and slidably connected to the track such that the foldable wall modules can be selectively moved between a closed confirmation and an open configuration. The foldable modular wall system can also include power hinge jumpers through which electrical wires can nm to power electronic components embedded in or disposed on the foldable wall modules.

A fire-rated receiver channel includes at least one intumescent or other fire-resistant material strip. The receiver channel can nest with a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed at a perimeter of a wall assembly to create a fire block arrangement. In other arrangements, a track assembly includes two nested tracks, an inner track and outer track. The assembly is designed so that the outside width of the outer track is equal to or less than the outside width of the inner track to present a substantially flush external surface for attachment of exterior sheathing elements when the assembly is used in an external wall.

A thermoplastic composite article comprising a porous core layer and an open cell skin disposed on a first surface of the core layer is described. The composite article comprises a noise reduction coefficient of at least 0.5 as tested by ASTM C423-17 and a flame spread index of less than 25 and a smoke development index of less than 150 as tested by ASTM E84 dated 2009.

A structural stud post assembly comprising a center receiver section having opposing receiver channels formed by side walls and angled flanges, and a pair of raceway inserts also defining a raceway channel for accepting wiring and equipment to be disposed in the raceway. The raceways can be installed in the receiver channels to accept and accommodate wiring and equipment. The center receiver comprises a thermal break at about a midpoint to prevent there from being a metal-to-metal thermally conductive pathway through the stud. The structural stud post may be used in the construction of modular building systems.

An exemplary robotic parking device of the present disclosure includes a number of stacks of containers. The stacks being positioned within a frame structure including uprights and a horizontal grid disposed above the stacks. The grid having substantially perpendicular rails on which load handling devices can run. Cars or vehicles are positioned in containers and are moved into and out of the stacks by the robotic handling devices running on the grid. The cars are put into the grid at entry points that may be positioned at points under the stacks.
