  • Patent number: 11421340
    Abstract: In one embodiment employing a vertical draw apparatus, a method of crystallization growth on a substrate surface of a substrate having a substrate material includes: mounting the substrate to a sample holder with the substrate surface facing a liquid surface of a reservoir disposed in a chamber that provides an ambient temperature; seeding the substrate surface with seed droplets; lowering the substrate surface to the liquid surface of the reservoir; independently controlling a temperature of the substrate and a temperature of the reservoir to produce a temperature difference between the substrate and the reservoir over a period of time for crystallization growth; and retracting the substrate surface from the liquid surface of the reservoir at a draw rate. The draw rate and the temperature difference are selected to grow polycrystalline laminate on the substrate surface. Consistent polycrystalline columnar microstructures are formed with appropriate seeding of the substrate surface.

  • Publication number: 20220259220
    Abstract: This invention outlines a method for synthesizing a blended resin system in a one pot reaction that may utilize, for example, bio-based anhydrosugars such as isosorbide as a principle component to produce isosorbide dimethacrylate and other monomeric materials for thermosetting applications. This invention establishes a one-pot procedure for reacting a hydroxy group containing compound with methacrylic anhydride in the first step and using the by-product methacrylic acid to react with glycidyl ethers to form additional methacrylate compounds in the second step. This methodology can be formulated to produce a wide array of resin systems that have controlled ratios of hydroxy group containing compound/cross-linker/reactive diluent. Additionally, the novel resin systems may be partially to fully bio-based, promoting global sustainability and reducing costs, and when free radically polymerized have properties that meet or exceed their petroleum derived counterparts.

  • Patent number: 11402322
    Abstract: Processes, compositions, and sensors for sensing a variety of toxic chemicals based on colorimetric changes. Exemplary process for sensing a toxic chemical includes contacting a toxic chemical, or byproduct thereof, with a sorbent that includes a porous metal hydroxide or a porous mixed-metal oxide/hydroxide and a transition metal reactant suitable to react with a toxic chemical or byproduct thereof. The sorbent is contacted with the toxic chemical or byproduct thereof for a sampling time. A difference between a post-exposure colorimetric state of the sorbent and a pre-exposure colorimetric state of the sorbent is determined to thereby detect exposure to, or the presence of, the toxic chemical or byproduct thereof.

  • Patent number: 11402185
    Abstract: A projectile having a spin stabilized gyroscopically stable flight path due to a base flange. With the base flange, the aerodynamic overturning moment about the center of gravity is reduced to increase the gyroscopic stability factor for stable flight. In one application, a medium-caliber untethered human electro-muscular incapacitation (HEMI) projectile has improved effectiveness due to its stable flight from launch to targets. Other applications for damping resulted in significant improvement in ground dispersion of 40 mm projectiles. The increased stability and increased aerodynamic damping reduce coning motion during flight which ensures that the projectile arrives at the target with greater accuracy, and with its nose oriented for effective incapacitation of the target.

  • Patent number: 11402188
    Abstract: A two piece aerodynamic pusher consisting of a body and tailpiece. This pusher fits into a standard 40 mm cartridge case by means of three sabots. After the cartridge case is functioned, the combustion gases push the projectile forward and ignite a delay column located in the rear of the pusher. Upon muzzle exit, the sabots discard and the pusher continues down range as the delay column burns. Once the delay has burned, a charge located in the pusher body is ignited, pushing the payload out of the front of the projectile. The cap pops off, and the pellets are dispersed. This effectively moves the payload release point from the muzzle until a designated point down range based on the delay length.

  • Patent number: 11387802
    Abstract: A hybrid ferroelectric/non-ferroelectric piezoelectric microresonator is disclosed. The hybrid microresonator uses a ferroelectric layer as the actuator as ferroelectric materials typically have higher actuation coefficients than non-ferroelectric piezoelectric materials. The hybrid microresonator uses a non-ferroelectric piezoelectric layer as the sensor layer as non-ferroelectric piezoelectric materials typically have higher sensing coefficients than ferroelectric materials. This hybrid microresonator design allows the independent optimization of actuator and sensor materials. This hybrid microresonator design may be used for bulk acoustic wave contour mode resonators, bulk acoustic wave solidly mounted resonators, free-standing bulk acoustic resonators, and piezoelectric transformers.

  • Patent number: 11386243
    Abstract: A method for screening a large design space of compositions with possible application as binders in cermet and powder metallurgy applications allows rapid elimination of large portions of the design space from contention so that resource intensive procedures, such as computationally intensive modeling techniques and experimental testing, can be focused on potential binder compositions with a high likelihood of being used successfully. The method relies on parameters such as surface tension, contact angle, viscosity, a special capillary metric that is used to characterize capillary behavior, and melting point, which are relatively easy to calculate or determine, to screen out large portions of the design space. Exemplary binder compositions are obtained using the method.

  • Patent number: 11371916
    Abstract: An apparatus for passive sampling of airborne particles such as those found in an aerosol is disclosed. The passive sampler is designed to take advantage of natural air flow to collect airborne particles, such as those contained in an aerosol, for subsequent analysis. The passive sampler increases the sampling efficiency for diffusion and electrostatic collection of particles by using natural airflow or movement to bring particles closer to the deposition surface. Alternately charged electret filters further increase the sampling efficiency.

  • Patent number: 11371819
    Abstract: A packaging arrangement for 30 mm×173 mm ammunition rounds. The packaging arrangement has a heavy duty standoff device of defined height, which standoff device mounts a very high strength support plate and a heavy duty restraining plate. The support plate has through holes (of diameter slightly less than the rounds defined maximum diameter) to hold the rounds of in an upside down position and from sliding/moving. The height of the standoff device keeps the rounds from being able to touch the bottom of the metal box. The restraining plate has multiple recessed areas sized to accommodate the back ends of the said rounds. The packaging arrangement is lowered into a metal box with handles for carriage purposes. On top, there are Homosite filler pads, and the box accommodates a top lid.
