  • Publication number: 20200246891
    Abstract: A welding or additive manufacturing wire drive system includes a first drive roll and a second drive roll. One or both of the drive rolls has a circumferential groove for simultaneously driving both of a first wire electrode and a second wire electrode located between the drive rolls in the circumferential groove. A sensor device generates a signal or data corresponding to a consumed or remaining amount of one or both of the wire electrodes. The first wire electrode contacts the second wire electrode within the circumferential groove. The first wire electrode further contacts a first sidewall portion of the circumferential groove. The second wire electrode further contacts a second sidewall portion of the circumferential groove. Both of the wire electrodes are offset from a base portion of the circumferential groove, said base portion extending between the first sidewall portion and the second sidewall portion of the circumferential groove.

  • Publication number: 20200160012
    Abstract: This invention provides a system for separating a field of view (FOV) of a scene imaged by a vision system camera assembly, in which a separating mirror assembly redirects a first optical path of at least a first optics with respect to at least a first image sensor in the camera assembly. A first reflecting assembly redirects the first optical path from the separating mirror toward a first FOV. The first optical path is extended free of splitting the image. The separating mirror assembly redirects a second optical path of a second optics with respect to a second image sensor in the camera assembly. A second reflecting assembly redirects the second optical path from the separating mirror toward a second FOV. The second optical path is extended free of splitting the image projected from the scene on the second image sensor.

  • Publication number: 20200114452
    Abstract: A welding or additive manufacturing wire drive system includes a first drive roll having a first annular groove, a second drive roll having a second annular groove, a first welding wire located between the drive rolls in the annular grooves, and a second welding wire located between the drive rolls in the annular grooves. A biasing member biases the first drive roll toward the second drive roll to force the first welding wire to contact the second welding wire. The first welding wire contacts each of a first sidewall portion of the first annular groove, a first sidewall portion of the second annular groove, and the second welding wire. The second welding wire contacts each of a second sidewall portion of the first annular groove, a second sidewall portion of the second annular groove, and the first welding wire. The drive rolls rotate in opposite directions thereby moving the welding wires through the wire drive system.

  • Patent number: 9145549
    Abstract: Cytochrome P450 BM-3 from Bacillus megaterium was engineered using a combination of directed evolution and site-directed mutagenesis to hydroxylate linear alkanes regio- and enantioselectively using atmospheric dioxygen as an oxidant. Mutant 9-10A-A328V hydroxylates octane primarily at the 2-position to form S-2-octanol (40% ee). Another mutant, 1-12G, hydroxylates alkanes larger than hexane primarily at the 2-position, but forms R-2-alcohols (40-55% ee). These biocatalysts are highly active for alkane substrates and support thousands of product turnovers. These regio- and enantio-selectivities are retained in whole-cell biotransformations with E. coli, where the engineered P450s can be expressed at high levels and the expensive cofactor is supplied endogenously.
