Patent number: 10220594Abstract: Hydrophobic thermal insulation fiberglass flexible blanket using a textile grade fiberglass is produced by impregnating a hydrophobic polymer (e.g. a fluoropolymer) dispersion into a fiberglass blanket/mat, such as a needle felted fiberglass (FG) blanket/mat. The preferred FG needle felt blanket is a mechanically, rather than organically, bound glass fiber insulating blanket. The hydrophobic polymer dispersion forms a hydrophobic coating on the surface of the fiberglass filaments. Integral hydrophobicity is achieved and maintained without the need to add commonly-used hydrophobic inorganic particles, such as treated silica aerogels or fumed silica. Optionally, to enhance overall hydrophobicity and to inhibit fibrous surface lofting, a super-hydrophobic coating of fluoropolymer and inorganic particles such as silica particles may be dispersed onto one or more surfaces of the blanket.Type: GrantFiled: July 19, 2017Date of Patent: March 5, 2019Inventors: Lewis Dill, Chengjun Zhou

Patent number: 10189033Abstract: A process and apparatus are disclosed for the deposition of a layer of a first material onto a substrate of a second material. Powder particles of the first material are entrained into a carrier gas flow to form a powder beam directed to impinge on the substrate. This defines a powder beam footprint region at the substrate. The powder beam and the substrate are moved relative to each other to move the powder beam footprint relative to the substrate, thereby to deposit the layer of the first material. A laser is operated to cause direct, local heating of at least one of a forward substrate region and a powder beam footprint region. The laser beam direction is defined with reference to a plane coincident with or tangential to a surface of the substrate at the center of the laser beam footprint in terms of an elevation angle from the plane to the laser beam direction and in terms of an acute azimuthal angle from the movement direction to the laser beam direction.Type: GrantFiled: October 26, 2012Date of Patent: January 29, 2019Assignee: Laser Fusion Technologies Ltd.Inventors: Martin Sparkes, William O'Neill, Andrew Cockburn, Rocco Lupoi, Matthew Bray
