    摘要: An ammunition projectile puller includes a body with one or more jaws to engage the projectile. The jaws can generally displace axially or radially relative to an axis of a through opening, and/or rotate around an axis transverse to the through axis, all within a predetermined range of motion. The jaws obtain a reliable purchase on the projectile to facilitate the extraction. The extracted projectile is cleared from the puller by the insertion of the next projectile to be extracted. The device is thus self-locating, self-locking, self-clearing, tolerant of projectile variation, operable with different projectile types and calibers, reliable, and efficient.

    摘要: A heat exchange component includes a part configured for exchanging thermal energy, the part is formed of at least one solid state Martensitic transformation phase change material which is configured to readily undergo a solid-solid martensitic transformation from one crystalline structure to another different crystalline structure during a change in temperature in the normal and/or anticipated operating temperatures of the heat exchange component. In some embodiments, the system further includes a temporally-evolving external temperature/heat source which changes the temperature and resultant phase of the solid-state phase change material. The temporally-evolving external temperature/heat source may involve a solid conducting material or electronic/photonic component, a fluid, a plasma, and/or a radiation source. The heat exchange component may be configured as a flat plate, tube, finned structure, porous structure, graded structure, cold plate, heat exchanger, condenser, evaporator, or any component generally regarded as a thermal energy storage or heat transfer structure in various embodiments.

    摘要: A thermal energy storage (TES) device includes a thermoelectric cooler; and a metallic phase change material (PCM) within the thermoelectric cooler. The PCM may include any of gallium or its alloys, low temperature fusible alloys, and solid metal shape memory alloys. A thermoelectric effect within the PCM is to transport heat in the thermoelectric cooler. The TES device may include a graded oxide layer adjacent to the PCM to serve as a distributed electrical junction in the thermoelectric cooler to create a hot side thermoelectric junction in a bulk volume of the PCM. The graded oxide layer may include α-IGZO. The TES device may include a high-thermopower corrugated metal foil layer comprising barrier oxides patterned therein. The high-thermopower metal foil layer may be adjacent to the graded oxide layer. The TES device may include a dielectric layer adjacent to the high-thermopower corrugated metal foil layer.
