Title: Esterification of acetic acid recovered from wood acetylation with alcohols
Inventor: JANKA MESFIN
IPC: C07H3/06
Filed: 2019-12-16
Abstract: An esterification process that uses an acetic acid composition from a wood acetylation process as a reactant. Even though the acetic acid composition contains impurities, such as ethyl acetate, methyl acetate, acetaldehyde, acetone, terpenes and/or terpenes derivatives, the impurities do not adversely affect the quality of the ester products. This process can be economically advantageous by using cheaper acetic acid - one sourced directly from a wood acetylation process.

Title: Bubble-free liquid filling of fluidic chambers
Inventor: MYERS FRANK B
IPC: G01N21/05
Filed: 2020-03-03
Abstract: This invention relates generally to devices, systems, and methods for avoiding bubble formation in a fluidic chamber during filling of the fluidic chamber with a liquid. A first and second piece are operatively coupled to form the fluidic chamber. A protrusion protrudes into a volume of the fluidic chamber such that there is a distance of minimal approach between an apex of the protrusion and a surface of the fluidic chamber. The protrusion forms a channel that extends from one of an inlet and the outlet of the fluidic chamber to the protrusion apex. A maximum distance of travel through the fluidic chamber volume exists between the inlet and the outlet. A cross-sectional area of the fluidic chamber volume increases from the protrusion apex to a transverse plane of the fluidic chamber and decreases from the transverse plane to the other one of the inlet and the outlet.
