Abstract: The instant invention is a ladder accessory in the form of a toolbox. The toolbox is coupled to support brackets mounted on each front leg of a conventional ladder. The toolbox includes a handle that allows for securing to the brackets when the cover is opened by forcing pinions located in the bottom of the box through pinion apertures located on each support bracket. The support bracket allows lifting of the toolbox so as to provide a safe working area for a worker on top of the ladder allowing ease of access to the necessary tools in order to accomplish a particular task. Bracket release levers are provided on each support bracket to allow lifting of the toolbox in a convenient manner.

Abstract: A laser ring mirror assembly is disclosed which supports and cools an annular ring mirror of a high powered laser with a cooling manifold which has a coolant flow design which is intended to reduce thermal distortions of the ring mirror by minimizing azimuthal variations in temperature around its circumference. The cooling manifold has complementary pairs of cooling passages each of which conduct coolant in opposite flow directions. The manifold also houses adjusters which vary the depth between the annular ring mirror and each cooling passage, and which vary the flow area of the cooling passage to produce a control over the cooling characteristics of the cooling manifold.
