  • Publication number: 20220008889
    Abstract: A change of state of weed seeds to having reduced germination viability in one minute by illuminating a seed in a processing theater to achieve at least one of 0.66 J/cm2 cumulative illumination energy, and 0.06 W/cm2 irradiance, of at least one of an Indigo Region Illumination Distribution (IRID), and Medium Wavelength Infrared (MWIR) radiation, preferably 2-8 microns, with no high energy transfers, scalding, heat shock, cooking or incineration. The MWIR radiation from heated borosilicate glass or glass powder at just under 500 C offered a peak MWIR emission of 3.75 microns, and was unexpectedly effective, and can be used in a radiant and transmissive weed seed accumulator transport belt. The process can be incorporated into a harvester combine to convert a tailings flow prior to discharge on an agricultural field. An illuminated harvest combine using an illuminator according to the invention allows reduction of the weed seed bank.

  • Patent number: 4827604
    Abstract: A rotor (100,200,300l ) for a stator (50) of a rotary switch (10) includes a substrate (106,216,302) having a continuous conductive surface over which a profiled dielectric layer (110,218,316) is molded which includes arcuate groove segments (118) along concentric circles which expose portions of the continuous conductive surface and define switch-encoding circuit paths (120,222,322) for brush contact portions (66) of the stator (50). The dielectric material at the ends (122) of each groove segment (118) deflect the brush contact portions (66) away from the conductive surface during rotation of the rotor (100,200,300), and the brush contact portions thus do not engage corner edges of discrete circuit paths. Each layer (110,218,316) can have an annular detent surface (132,234,324) of a plurality of pointed embossments (130,230,326) defining radial grooves (136,232,328) therebetween at switch locations, cooperable with detent (74) of the stator (50) to accurately position the rotor (100,200,300) upon rotation.

  • Patent number: 4792449
    Abstract: This invention relates to a method for administering drugs. In particular a lipophilic drug is solubilized by a food, such as chocolate, and admixed with an oil-based carrier. The lipid soluble drug is thus conveyed to the gastrointestinal tract. Because this type of food is digested readily, the drug is absorbed as intended, and the dose is not subject to day-to-day variations.

  • Patent number: 4686333
    Abstract: An inner rectangular housing insertable into a cavity of an outer rectangular housing has latching projections on sidewalls near the bottom to latch into latching recesses on inside surfaces of the sidewalls of the outer housing near the cavity entrance. Endwalls of the inner housing have stress ledges near the bottom to deflect outwardly the endwalls of the outer housing to generate permanent tension which is transferred by integral wall corners to the sidewalls of the outer housing to urge them inwardly to maintain the latched condition of the projections and recesses. Such latching and tensioning is useful in the type of electrical switch assemblies whose housings are under long-term stress, vibration and/or heat even when bonded and sealed.

  • Patent number: 4403107
    Abstract: A circuit board is fabricated comprising a metal layer laminated to an underlying dielectric substrate. Portions of the metal layer are separated and recessed into stable indented portions of the substrate by a stamping die, roller, or the like. The substrate is composed of a cellular material, for example, polysulfone impregnated with hollow glass spheres, whereby the indented portions of the substrate are compacted by impression of the die profile to receive separated portions of the metal layer therein.

  • Patent number: 4363930
    Abstract: A circuit board is fabricated from a metal layer laminated to an underlying dielectric substrate. A stamping die, or roller, formed with a deeply impressed pattern of circuit paths, is indented through the metal and into the substrate. The metal is formed into circuit path conductors, electrically isolated from one another by insetting sheared away portions of the metal into indented portions of the substrate.

  • Patent number: 4332987
    Abstract: A DIP switch is disclosed comprising improved sliding actuator means receivable within a rectangular housing channel. The slide actuator comprises a dielectric body having a plurality of parallel arms projecting forward therefrom, with each of the arms having a free, reversely formed end segment projecting backward in superior relationship to the actuator body. The slide actuator further comprises a plurality of parallel conductive arms, electrically and mechanically connected at one end, and projecting rearwardly from the actuator body. Each of the conductive arms is formed to provide a reversely-bent depending end segment projecting downwardly for engaging and interconnecting appropriate circuitry in the housing channel. A cover is further provided for enclosing the top of the housing channel, and provides a series of corrugations along a bottom surface thereof which are engaged by the superior actuator arm segments to register the actuator slide body along the housing channel.
