Disclosed is a work support having an extendable support beam for spanning between a pair of leg assemblies. The extendable support beam includes one or more elongated rails having a first end, a second end, an upper edge, a lower edge, a middle portion disposed between the upper edge and the lower edge, where the upper edge and the lower edge each extend away from the middle portion and form a channel having an interior surface and an exterior surface, and a t-track extending longitudinally along the interior surface. The work support includes the extendable support beams and a leg mount disposed between the pair of elongated rails, and a pair of legs pivotally coupled with the leg mount and moveable between a storage position where the pair of legs are secured within a cavity, and a working position.

Systems, apparatus, methods, and techniques of assembly of discrete modules of a control panel are disclosed. The modules can be independently wired, tested, and installed into a control panel. Module definitions are defined specifying components to perform the electrical function, a mechanical arrangement of the components, electrical connections, and logical interactions of the module. A bill of materials can be generated based on a designation of a set of modules for a control panel and the module definitions. Modularly assembled control panels are disclosed. An assembly frame is described herein for temporarily mounting components of a module for independent assembly of a control module and for eventual removal and installation into a control panel frame. The assembly frame may include a faceplate frame and side frames and temporary mounting features.

The present disclosure relates to methods and apparatus for launch and recovery of a remote inspection device within a liquid storage tank. In one embodiment, the tank is accessed by opening an entrance hatch and then injecting a vapor suppression foam across a surface of a stored liquid mass to form a foam layer. A launching system having a remote inspection device is attached to the entrance hatch to define a launch and recovery space sealed from an external environment and isolated from the stored liquid mass in the tank via a valve and the foam layer. The launch and recovery space is purged of hazardous vapors by injection of an inert gas prior to launch and recovery of the remote inspection device. Prior to removal of the launching system, the surface of the stored liquid mass is re-coated with vapor suppression foam.

A rotatable member is mountable on a tabletop of a power tool apparatus. The rotatable member includes a first work surface and a second work surface. The first work surface is on a first side of the rotatable member. The second work surface is on a second side of the rotatable member. The second side is different from the first side. The rotatable member is configured to move into a first position such that the first work surface is level with a surface of the tabletop. In addition, the rotatable member is configured to move into a second position such that the second work surface is level with the surface of the tabletop.

A table comprising a worktop including an axis of rotation, a perimeter, and an effective radius, the effective radius defined as the average distance between the axis of rotation and the perimeter; a frame; a rotational connection disposed between the worktop and the frame, the connection configured to allow the worktop to rotate about the axis of rotation; and a plurality of bearings disposed between the worktop and the frame to rollingly support the worktop on the frame, at least one of the bearings disposed more than half of the effective radius from the axis of rotation.

A table is disclosed. The table comprises a table base and tabletop. The table base comprises a top surface with a replaceable adhesive layer attached. The tabletop comprises a first usable side and a second usable side, the first usable side and the second usable side being alternately attached to the replaceable adhesive layer once the adhesive is cut, removed, and replaced. The top surface further comprises a rounded edge that acts to guide the entry of an adhesive cutting wire. The replaceable adhesive layer comprises embedded wire guides that define a cutting zone substantially the width of the cutting wire through the adhesive. The embedded wire guides restrict the cutting wire to the cutting zone while the adhesive is being cut, thereby allowing the first usable side and the second usable side to be alternately attached to the adhesive layer.

A workbench comprising a first support, a second support and a first work surface, in which said first support comprises a leg structure with an upper end, in which said first work surface comprises a first end, in which said upper end and said first end comprise a connection means to releasably connect them together, and in which said connection means comprises a first pair of parallel elongate troughs provided on either said upper end or said first end, and a first pair of parallel elongate flanges provided on the other of said upper end or said first end, which first pair of flanges is shaped and configured to be releasably engagable in said first pair of troughs.
