A closure member control system for roll down smoke and/or gas barrier system includes a closure member which, when closed, maintains a spool with the barrier wound thereon within a housing. On deployment, the closure member opens and is prevented from closing by one or more cords connected to the spool.

A multi-layer rolling fire curtain assembly includes: a multi-layer fire curtain wrappable about a roller and to be deployable between an extended position and an open position, such that a free end of the curtain is movable between a retracted position and an extended position. The fire curtain has a fire resistant inner curtain layer having a first width between first and second lateral edges, and a fire resistant outer curtain layer arranged opposite the inner layer and having first and second scalloped lateral edges varying between the first width and a second width less than the first width. The inner and outer layers are affixed to one another by horizontally oriented connection seams at the first width, the connection seams being configured so that the outer and inner layers are spaced apart by a plurality of baggy areas formed between adjacent connection seams.

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 real-time damper visual verification device and system for use in combination with a HVAC duct structure includes a camera being structured and disposed for generating image signals in response to an optical image and the camera being in connection with a computer processor for generating the optical image and a real-time clock display; the camera being positioned for viewing the damper blades of the HVAC duct structure; wherein a verification procedure includes operating of the plurality of damper blades between first and second movements, the first movement defining the damper blades moving from an open position to a closed position and the second movement defining the damper blades moving from a closed position and an open position; and in which the camera records the optical images of the first and second movements to provide a true visual verification of operation of the damper blades between the first and second movements.

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.

A storage system is described where goods are stored in containers and the containers are stored in stacks. Above the stacks runs a grid network of tracks on which load handling devices run. The load handling devices take containers from the stacks and deposit then at alternative locations in the stacks or deposit then at stations where goods may be picked out. The framework may be provided with one or more of the following services: power, power control, heating, lighting, cooling, sensing, and data logging. The provision of these services within the framework rather than across the system as a whole, allows for flexibility in storage whilst reducing cost and inefficiency.

A method of partitioning the storage system prevents the spread of fire or prevent damage caused by sprinkler activation.

A storage system is disclosed where goods can be stored in containers and the containers are stored in stacks. Above the stacks runs a grid network of rails (e.g., tracks) on which load handling devices can run. To take containers from the stacks and deposit then at alternative locations in the stacks or deposit then at stations where goods may be picked. The framework may be provided with one or more of the following exemplary services: power, power control, heating, lighting, cooling, sensors, and data logging devices. The provision of these services within the framework rather than across the system as a whole, can allow for flexibility in storage whilst reducing cost and inefficiency.
