Abstract: A latch includes a catch pivotable about a first axis between a latched position for retaining a striker and an unlatched position for releasing the striker. The catch has a cam surface. A pawl is pivotable about a second axis and is engageable with the cam surface of the catch. In some embodiments, the pawl secures the catch in the latched position by resting on a first portion of the cam surface, the curvature of which is substantially concentric with the second axis when the catch is in the latched position. The pawl is movable off of the first portion of the cam surface to release the catch from the latched position. The catch can be drivable toward the latched position by the pawl.

Abstract: The present volume monitoring device (40) includes a cylindrical portion (66) having a piston assembly (100) therein. The cylindrical portion (66) having a measuring device (48) attached thereto at one end (46) and a readout gage (44) attached thereto at an other end (50). The measuring device (48) including a plurality of plungers (181) which when the volume displacement monitoring device (40) is positioned within an opening activates a flow of fluid to move the piston assembly (100) and establishes a readout on the readout gage (44). The volume displacement monitoring device (40) provides an economical way of monitoring the size of an opening. Furthermore, the volume displacement monitoring device (40) can be used in the field and does not require additional environmental protection to remain within safety standards.
