  • Patent number: 12105418
    Abstract: Precursor solutions for radiation patternable coatings are formed with an organic solvent and monoalkyl tin trialkoxides in which the water content of the solvent is adjusted to be within 10 percent of a selected value. Generally, the water content of the solvent is adjusted through water addition, although water removal can also be used. In some embodiments, the adjusted water content of the solvent can be from about 250 ppm by weight to about 10,000 ppm by weight. With the appropriate selection of ligands, the adjusted precursor solutions can be stable for at least about 42 days, and in some cases at least 8 months.

  • Patent number: 12104712
    Abstract: An improved mechanical dump valve for a liquid level control system. The dump valve comprises a splined shaft that communicates with the valve actuator by a toothed member, such as a splined bore in a dump valve hub. The dump valve also may include pressure ports. Still further, the present invention includes a liquid level control system comprising a trunnion assembly and a mechanical dump valve in which the trim motion of the float valve is transmitted by means of splined shafts in both the trunnion assembly and the dump valve assembly. The inventive system may comprise float weights for weighting the float accurately without having to drill the float and load it with sand or other weighting material. Also included is a kit for retrofitting existing liquid level control systems that use D-shaped connections with splined components.

  • Patent number: 12072343
    Abstract: A method includes, under control of control circuitry implementing a mixing protocol, aspirating reagents from multiple different reagent reservoirs into a cache channel. Designated amounts of the reagents are automatically aspirated from the corresponding reagent reservoirs by corresponding sippers based on the mixing protocol implemented by the control circuitry. The method also includes discharging the reagents from the cache channel into a mixing reservoir, and mixing the reagents within the mixing reservoir to form a reagent mixture.

  • Patent number: 7488222
    Abstract: A pair of mating connectors includes a receptacle having an insulative housing and at least one conductive receptacle contact with a pair of spaced walls forming a plug contact receiving space. The plug connector has an insulative housing and at least one conductive contact having a pair of spaced walls which converge to form a projection engageable in the plug receiving space of the receptacle contact. In each case, the spaced walls are joined by a bridging structure that unites the walls. The plug and receptacle contacts are retained in the respective housings by engagement of opposed lateral edge portions of the contacts with the housings in a manner to enhance heat dissipation by convection by maintaining substantial portions of the contacts spaced from the housing walls and from each other. The bridging structure may include a retention element for engaging respective connector housings to retain the contact in the housings.

  • Patent number: 7314377
    Abstract: A pair of mating connectors includes a receptacle having an insulative housing and at least one conductive receptacle contact with a pair of spaced walls forming a plug contact receiving space. The plug connector has an insulative housing and at least one conductive contact having a projection engageable in the plug receiving space of the receptacle contact. The open structure of both the receptacle and plug contacts enhances heat dissipation and allows flexibility in achieving desired contact normal forces. The contact construction is especially useful for electronic power connectors.

  • Patent number: 6230392
    Abstract: Disclosed is a method and apparatus for mounting an electrical connector on a printed wiring board. The printed wiring board is initially positioned on locating projections on a tooling plate. Eyelets are positioned in hold down apertures in the connector. The hold down apertures initially engage the locating projections to align the connector pins with pin receiving apertures on the printed wiring board. Engagement continues until the pins are positioned in the apertures and the lower end of the eyelet is deformed to engage the innerside of the down aperture and the lower side of the printed wiring board.

  • Patent number: 5899771
    Abstract: Disclosed is an assembly which comprises a printed circuit board on which there is mounted a component of an electrical connector. The printed circuit board and the electrical connector component have aligned mounting apertures. A boardlock member extends axially through these apertures and has a mounting foot engagement structure from which two resilient spaced legs depend. These spaced legs each have projections which are axially spaced from one another so that the connector member may engage a circuit board of one thickness on the projection of one leg and also engage a circuit board of another thickness by the projection on the other leg.
