Abstract: This application relates to a building energy analysis and management system for measurement and verification of building performance. The system can analyze, optimize, manage, maintain, trouble shoot, and/or modify building systems, such as HVAC systems, in connection with the building energy usage. Measurements may be gathered for one or more HVAC units coupled to pressure independent valves, and sent to one or more Surge Panels that pass data to remote analysis servers, which can receive other system or external data. The analysis servers compare measurements to predicted values and can standardize the predicted values to account for external conditions. The comparison can result in difference values used to generate probable causes and optimization recommendations. The system outputs reports or other data display using a graphical user interface that can be adjusted for an anticipated user.

Abstract: A toilet tank lever assembly may be mounted in various toilet tanks by selective positioning of a long lever arm relative a short lever arm. One such lever assembly includes a long lever arm which may be mounted at an infinite degree of adjustment relative a short lever arm as provided by a ball and socket interface between the lever arms. The ability to reverse the short lever arm essentially doubles the number of mounting possibilities. By selecting between a front insert and a side insert, a handle is readily positioned for either front or side tank mounting. Various handles may also be readily attached to the lever post to provide various aesthetic appearances.

Abstract: A wellbore fluid treatment apparatus capable of being actuated by a sealing device. The apparatus includes a casing including a bore and a casing port opened through the wall of the casing. The apparatus also includes a sleeve located within the casing bore. The sleeve includes a sleeve port opened through the wall of the sleeve and a baffle seat forming an inner flow area and configured to receive the sealing device. The sleeve is moveable by the sealing device between a closed position preventing fluid flow from the bore through the casing port and an open position allowing fluid flow from the bore through the sleeve port and casing port. The apparatus also includes a reverse cement shoe attached to the casing. The reverse cement shoe has a valve that allows the casing to be cemented by displacing cement only on the outside of the casing.
