  • Patent number: 11262489
    Abstract: A method of making a multi-layer coating on a substrate is provided and involves applying a mirror coating to a substrate then spraying a silicate topcoat onto the mirror coating. Applying the mirror coating can involve applying a reflective material to the substrate to form a reflective layer and applying an oxide layer to the reflective layer to form the mirror coating. The oxide layer can be made of one or more oxide layers, and each of the one or more oxide layers can include aluminum oxide, silicon oxide, or a combination thereof. The multi-layer coating provides increased IR emittance and decreased solar absorptance relative to conventional thermal control coatings.

  • Patent number: 11261335
    Abstract: A method of making a thermal control coating is provided. A primer layer can be applied to a substrate to form an exposed surface. The primer layer can include an epoxy binder and a silica filler. The exposed surface can be treated with an oxygen plasma to form a treated surface. A silicate-based thermal control coating can be applied to the treated surface, for example, by spraying, to form a thermal control coating on the substrate. Spacecraft and spacecraft hardware components coated with the thermal control coating, are also provided.

  • Patent number: 10815013
    Abstract: A laminate has a composite coating on a substrate. The substrate is a polymeric substrate with a surface resistivity of 4×102 to 1×108?/?; or a textured substrate with surface features which are 100 nm to 10 microns high. The composite coating comprising a tie layer of a nickel-chromium alloy; a layer of a reflective metal; a layer of aluminum oxide; a layer of silicon oxide; and optionally a layer of indium tin oxide. The laminate has a solar absorbance at a wavelength of 0.25 microns to 2.5 microns of between 0.07 and 0.7; and the laminate has an IR emittance of 0.1 to 0.8. Solar absorbance and IR emittance of the laminate may be independently to control the ratio of solar absorbance to IR emittance. Solar absorbance may be adjusted by changing the surface resistance or degree of texturing on the substrate. IR emittance may be adjusted by changing oxide film thickness.

  • Patent number: 7863997
    Abstract: A compact, high speed, miniaturized adaptive controller for a microwave power generator. A pair of directional couplers are arranged between a microwave source and a circulator to measure forward and reverse power. An electromagnet in the circulator may be controlled in response to a VSWR calculation. In some arrangements, the directional couplers may be loop-type directional couplers that are integrated into a waveguide magnetron launching assembly. The directional couplers may use a tapered coaxial line that presents an impedance that reduces along the length thereof. This enhances the directivity of the loop coupler and improves performance of the controller.

  • Publication number: 20030209542
    Abstract: An apparatus, system, and method, for using circular mode magnetic microwave energy to heat the food product in a continuous microwave process. The microwaves are generated and transmitted as rectangular waveguide mode microwave energy, and are converted by mode converters to circular magnetic mode microwave energy. As circular magnetic mode microwave energy, the microwave energy passes through a food material and is reflected on the other side back into the food material, thus travelling through the food material a second time. Reflected microwave energy from the main reflected wave as well as reflections from other structures, surfaces and layers in the system travel back toward the microwave source. They are sensed, and a computer tuning system causes capacitive probes to generate offsetting microwave reflections, which are opposite in phase and equal in magnitude to the sum of all of the reflected waves.

  • Patent number: 6075422
    Abstract: A high power microwave or radio frequency network is disclosed which utilizes [2] two movable capacitive probes in order to provide complete vector tuning [in 4 axis by] utilizing the capacitive reactance of the two capacitive probes to provide [2] two tuning axis and the inductive reactance of two fixed inductive posts to provide [the] two additional [axis] axes of tuning, thereby allowing four axes of tuning with the movement of only two members, the capacitive probes. A third capacitive probe/inductive post set can be added to the two probe configuration for extremely high reflection correction at all phase angles.

  • Patent number: 5892208
    Abstract: An apparatus, system, and method, for using circular mode magnetic microwave energy to heat the interior regions of a work piece of wood fiber and glue. The microwaves are generated and transmitted as rectangular waveguide mode microwave energy, and are converted by mode converter to circular magnetic mode microwave energy. As circular magnetic mode microwave energy, the microwave energy passes through a work piece or billet of material is reflected on the other side, and travels through the billet a second time. Reflected microwave energy from the main reflected wave as well as reflections from other structures, surfaces and layers in the system travel back toward the microwave source. They are sensed, and a computer tuning system causes capacitive probes to generate offsetting microwave reflections, which are opposite in phase and equal in magnitude to the sum of all of the reflected waves.
