The present disclosure relates to PDE9 inhibitors, pharmaceutical compositions comprising the PDE9 inhibitors, and methods of using the PDE9 pharmaceutical compositions for the treatment of sickle cell disease (SCD).

PDE9 inhibitors for treating sickle cell disease

A casing stabbing apparatus which includes a derrick bracket subassembly for attachment to a derrick, and a boom having an end pivotally connected to the bracket assembly for pivotation about a vertical axis and about a horizontal axis. A pair of arcuate casing gripping jaws is pivotally connected to the second end of the boom. A piston and cylinder assembly extends between the jaws to selectively converge and diverge the jaws. A second piston and cylinder assembly extends between the bracket assembly and the boom to elevate the boom by pivotation about a horizontal pivotal axis. A third piston and cylinder assembly extends between the bracket assembly and the boom to swing the boom laterally in pivotation about a vertical axis. A remote automatic control subassembly enables the casing stabbing operation to be carried out from a remote location by the use of a hand held wand, and it includes remote control feedback circuitry which aids the operating in quickly and precisely positioning the boom for engaging the casing and moving it into a position of alignment.

This invention discloses a two-way tilting mechanism for use with infant bassinettes. It is comprised of a pivotable support adapted to receive an infant bassinette, a base upon which the support is pivotably mounted, a single-action pivoting mechanism connecting the support to the base, locking means for holding the support in a tilted position, and means for releasing the locking means.

Tilting mechanism for use with infant bassinette

A casing stabbing apparatus which includes a derrick bracket subassembly for attachment to a brace of a derrick, and a boom having an end pivotally connected to the bracket assembly for pivotation about a vertical axis and about a horizontal axis. A pair of arcuate casing gripping jaws is pivotally connected to the second end of the boom. A piston and cylinder assembly extends between the jaws to selectively converge and diverge the jaws. A second piston and cylinder assembly extends between the bracket assembly and the boom to elevate the boom by pivotation about a horizontal pivotal axis. A third piston and cylinder assembly extends between the bracket assembly and the boom to swing the boom laterally in pivotation about a vertical axis.

Casing stabbing and positioning apparatus

Apparatus for stabbing well casing to join casing sections to each other, including a rotary table assembly for supporting a casing section in a well bore, a derrick over the rotary table assembly, a crown block at the top of the derrick, a first piston and cylinder subassembly pivotally mounted on one side of the derrick over the rotary table assembly and below the crown block for pivotation about a horizontal axis, a second piston and cylinder subassembly pivotally mounted on a second side of the derrick for pivotation about a horizontal axis, with said second piston and cylinder subassembly located over the rotary table assembly and below the crown block and extending substantially normal to the direction of extension of the first piston and cylinder subassembly, cooperating casing clamping elements carried on the piston rods of the first and second piston and cylinder subassemblies, and counter balancing subassemblies connected to the first and second piston and cylinder subassemblies for pivoting the first and second piston and cylinder subassemblies to a vertically extending inoperative position.
