Abstract: A removable real time clock battery (“RRTCB”) assembly is disclosed herein. The RRTCB assembly has an outer housing removably mounted in a port of a downhole tool. The outer housing is adapted to receive at least a portion of an inner housing. The inner housing has a cavity therein and is mounted in the port of the downhole tool. The inner housing is removably disposed within the outer housing. A real time clock battery is removably disposed in the cavity of the inner housing. The real time clock battery electrically connects to a clock disposed within the downhole tool. The RRTCB assembly can be readily removed from the downhole tool or bottomhole assembly (while at the earth's surface) without otherwise disassembling the downhole tool. The real time clock battery can then be removed and replaced or installed if not present.

Abstract: A modular form panel for assembling a cast-in-place concrete structure includes an inner panel section and an outer panel section. A filling gap is defined between the inner and outer panel sections. The filling gap is configured to receive concrete poured on-site to form a concrete wall or roof section. One or more tie members span the filling gap interconnecting the inner and outer panel sections. The panel includes an integral side flange in some embodiments. When multiple panels are positioned adjacent one another, the adjacent side flanges form an end gap on each lateral side of the panel. The end gap has a thickness greater than the filling gap thickness. Concrete disposed in each end gap forms an integrated support column on each side of the panel. A bond beam gap is defined along the top edge of the panel having a greater thickness than the filling gap.
