  • Patent number: 11248459
    Abstract: Selectively automating the powering of downhole equipment during run-in-hole (RIH) operations provides a means of safely installing and monitoring downhole equipment. Selective automation comprises monitoring lowering of a pump assembly into a borehole as part of an installation process. In response to determining that the lowering of the pump assembly into the borehole has stopped, an output of power from a power source to a cable coupled to the pump assembly is allowed. A data transmission is communicated from a downhole gauge in the pump assembly to a communication device at a surface of the borehole via the cable. In response to not receiving a valid data transmission at the communication device, it is determined that the cable may be damaged, and that further cable testing should occur.

  • Patent number: 11021724
    Abstract: The subject invention concerns materials and methods for alkene reduction of compounds, such as levoglucosenone (LGO) and (S)-?-hydroxymethyl-?,?-butenolide (HBO), using an alkene reductase enzyme. In one embodiment, a method of the invention comprises alkene reduction of a target compound by reacting the compound with an Old Yellow Enzyme (OYE) that reduces alkene bonds. In one embodiment, the OYE is OYE 2.6 from Pichia stipites and comprises the amino acid sequence of SEQ ID NO: I. In a specific embodiment, the enzyme is an Old Yellow Enzyme (OYE) 2.6 mutant having an amino acid substitution at position 78 in the sequence, wherein the tyrosine at position 78 is substituted with a tryptophan amino acid (Y78W) and is designated as OYE 2.6 Y78W (SEQ ID NO:2).

  • Patent number: 7238870
    Abstract: A specialized at least bilayered device similiformic with the fretboard/fingerboard/keyboard of an instrument is designed to be removingly disposed between the strings and fretboard or frets of the instrument and prevents or mitigates fret damages (from, for example, dimpling or string grooving) owing to string pressures—such as during transport and storage of the instrument in a case or other. Fret integrity and active or functional life is extended in an industrially efficient, economical and elegant way heretofore uncontemplated and/or commercially realized.
