Abstract: A compression roller device includes markers on roller heads for pressure-rolling over a substrate to form visual indicia that the substrate has been properly pressure-rolled. In example embodiments, there are two roller heads that each have a set of markers and that are spaced-apart with a handle center-mounted between them. In this way, the roller heads have free/unobstructed outer/opposite edges so they can be positioned closely against an obstructing surface or element for rolling substrates in tight spots with limited clearance. Also, the recess defined between the inner/facing edges of the roller heads provides clearance for rolling over any protruding fasteners securing the substrate in place. Further, the spaced-apart marker sets provide for marking the visual indicia on both sides of a seam/joint between two adjacent panels in a panel-and-tape system to show that both longitudinal side portions of the tape have been pressure-rolled.

Abstract: The present invention describes a filter screen for removing debris from the hydraulic actuating fluid in an internal combustion engine having a hydraulic pump for supplying hydraulic actuating fluid to hydraulically-actuated unit fuel injectors. An upper portion of a priming reservoir is mounted on a front cover of the engine. The front cover forms a lower reservoir portion. A screen assembly is positioned adjacent to an interface defining an entrance from the upper reservoir portion to the lower reservoir portion. The screen assembly includes a filter screen enclosing the entrance to force the actuating fluid to pass through the filter screen, thus retaining debris that exceed the mesh size of the filter screen.

Abstract: The present invention describes a filter gasket (50) for removing debris from the hydraulic fluid in an internal combustion engine (10). An upper reservoir structure (30) is mounted on a front cover (14) of the engine (10) at interface (46). The front cover forms a lower reservoir (16). The upper reservoir structure (30) forms an upper reservoir (35). A gasket (42) is disposed along the interface (46) to seal the upper reservoir structure (30) to the front cover (14). A screen assembly (70) is positioned adjacent to the interface (46). The screen assembly (70) includes a filter screen (76) connected to a plate member (56). The plate member (56) operatively engages the gasket (42). The plate member (56) forces hydraulic fluid to pass through the filter screen (76), thus retaining debris that exceed the mesh size of the filter screen (76).
