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.

The present invention is directed to a roll-up wall. The roll-up wall and its components may be used to divide existing larger spaces into smaller spaces with a sound-attenuating barrier. In this invention a sound-attenuating panel is attached to a roller drum which, when turned on its axis by a winding mechanism, deploys or retracts the sound-attenuating panel. This invention discloses details of the sound-attenuating panel, the roller drum, a sound-attenuating guide system, a lower sound-attenuating seal, and an interlocking system. More particularly, this invention discloses an interlocking system which removably attaches a sound-attenuating panel to a roller drum. This invention discloses a plurality of embodiments of the interlocking system and provides detailed descriptions of each embodiment.

The present invention is directed to a roll-up, flexible, sound-attenuating wall system. More particularly, this invention relates to a retractable wall system and its components which may be used to divide existing larger spaces into smaller spaces with sound-attenuating barriers. In each unit the flexible, sound-attenuating wall is attached to a receiver tube which, when turned on its axis, deploys or retracts the flexible, sound-attenuating wall. The flexible, sound-attenuating wall is guided by a guide roller to intersect with other flexible, sound-attenuating walls at various angles. The receiver tube and guide roller are attached at either end to independent support brackets. This invention discloses a plurality of interlocking connector systems for connecting a plurality of flexible, sound-attenuating walls at various angles. Further, this invention discloses a winding mechanism disposed in and attached to receiver tube which turns the receiver tube on its longitudinal axis to deploy or retract the flexible, sound-attenuating wall.

The present invention relates to a device for installation into a hose and/or plastic pipe system and mounting of flow measurement sensors which comprises a plastic flow part as a hollow body with a centrally arranged and deformable region with a rectangular cross section. The present invention further relates to the use of the abovementioned device as well as to a method of flow measurement using the device.

An object handling system is described, the system having two substantially perpendicular sets of rails forming a grid above a workspace, the workspace having a plurality of stacked containers. The system includes a series of robotic load handling devices operating on the grid above the workspace, the load handling devices having a body mounted on wheels. The robotic devices can move around the grid under instruction from a computing device, the robotic devices being moved to a point on the grid above a stack of containers and then, using a lifting device, engage and lift a container from the stack. The container is then moved to a point where the objects in the container can be accessed. Modifications to the workspace and grid are described that allow vehicles and roll cages to be used to move stacks from the workspace to a point outside the workspace or from outside the workspace into the workspace.

A robotic parking device is described. The device includes a number of stacks of containers as shown in FIG. 3, 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 that are moved in to and out of the stacks by the robotic handling devices running on the grid. The cars are put in to the grid at entry points that may be positioned at points under the stacks.

A modular building system or storage system is disclosed with a number of stacks of containers as shown in FIG. 2, the stacks being positioned within a frame structure having uprights and a horizontal grid disposed above the stacks, the grid having substantially perpendicular rails on which load handling devices can run. Containers having functions associated with a number of residential or commercial uses are moved in to and out of the stacks by the robotic handling devices running on the grid. The containers disposed in the stacks are selected by function on demand by a user. In this way the building is reconfigurable to take in to account required uses.

A system and method for handling shipping containers is described. The container handling system includes a crane, the crane having crane load handling devices. The container handling system includes a conveyance device, the conveyance device including transversal load handling devices. The system provides storage and sortation for storing the containers in a series of stacks disposed beneath a grid, the grid having a series of load handling devices operable thereon. The crane load handling device removes a container from a ship, transports it to transversal load handling device operable on a conveyor. The container is moved on the conveyor to a transfer point where it is collected by a robotic load handling device for transport to the storage and sortation area.
