Abstract: A test stand for testing computer hardware components is provided. The test stand has a base structure. A first support arm mounts to the base structure. The first support arm has one or more apertures disposed therein to enable airflow through the support arm to avoid airflow hindrance of cooling fans during operation of the subject internal computer hardware components and when the test stand is in certain positions. A second support arm also mounts to the base structure. The second support arm has a rotation mechanism mounted therein. A support bracket for supporting the test subject computer hardware components extends between the first support arm and the second support arm. The support bracket is in communication with the rotation mechanism, such that the rotation mechanism controls and enables the rotation of the support bracket through a predetermined rotational degree range.

Abstract: A filtering device of the piston-cylinder type having a piston (P) and a cylinder (C) with reduced cross-sections (36) and (16) to create a pressurization chamber to force all fluids within the closed end of the cylinder into the piston as the piston is urged toward the closed end of the cylinder.
