Methods and apparatus for launch and recovery of a remote inspection device within a fluid 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.

The compound miter saw table includes a workshop table, a left side wing, and a right side wing. The workshop table is configured to support a saw. As non-limiting examples, the saw is a chop saw or a compound miter saw. The left side wing and the right side wing include articulated extensions that are deployed individually or together in order to support work material while the work material is being cut. The top surface of the workshop table is recessed below the top surfaces of the left side wing and the right side wing such that the work material rests evenly, supported by the saw, the left side wing, the right side wing, or any combination thereof.

A supporter for a woodworking table contains: four supporting rods, four driving columns, and two movable adjustment posts. Two middle sections of two of the four driving columns are rotatably connected with two middle sections of the other two of the four driving columns respectively, and one side of each of the four supporting rods is in connection with each of two ends of each driving column. The two movable adjustment posts parallelly correspond to each other, and each end of each of the two movable adjustment posts is rotatably connected with a middle section of each supporting rod. Each movable adjustment post includes an outer tube, an inner tube, and an adjustable stem. Thereby, the supporter of the present invention is collapsible so as to decrease its storage size. The supporter adjustably supports the table board based on a size of the table board.
