THERMOPLASTIC RUBBER
20220372257 · 2022-11-24 ·

PRISM Thermoplastic Rubber (PTR) is a novel, composite rubber material technology principally compounded from EOL, ambient ground, whole tires through the management of a unique process governed by the application of advanced, quantum field physics. The value from this technology is to provide a virgin-material-analog that may be readily integrated at high ratio, into new tire construction using conventional tire chemistry and manufacturing techniques resulting in a sustainable and significant, positive cost-benefit ratio as compared to current tire manufacturing economics.

Heat-assisted recording head having sub wavelength mirror formed of first and second materials

A recording head has a near-field transducer proximate a media-facing surface of the recording head. The near-field transducer extends a first distance away from the media-facing surface. A waveguide overlaps and delivers light to the near-field transducer. Two subwavelength focusing mirrors are at an end of the waveguide proximate the media-facing surface. The subwavelength mirrors are on opposite crosstrack sides of the near-field transducer and separated from each other by a crosstrack gap. The subwavelength focusing mirrors each include a first material at the media-facing surface and a liner that covers an edge of the mirror.

IMIDAZOLINE FUNCTIONALIZED OXIDIZED FATTY SUBSTANCE EMULSIFIERS AND METHODS
20170306067 · 2017-10-26 ·

Imidazoline functionalized oxidized fatty substance emulsifiers are made by obtaining a fatty substance composition; performing an oxidative oligomerization of the fatty substance composition to produce an oxidized fatty substance composition comprising from about 10 to about 75% by weight of oligomeric fatty acid components based on the total weight of fatty acid containing components in the composition; reacting the oxidized fatty substance composition with a polyamine comprising at least one ethylene diamine functional group with at least three hydrogens attached to the two nitrogens to form an aminoethylamido functionalized oxidized fatty substance composition; and forming an imidazoline functionalized oxidized fatty substance emulsifier from the amino-ethylamido functionalized oxidized fatty substance composition. Such compositions are particularly useful in asphalt applications and corrosion inhibition.

Use of sterols from animal waste as an additive in asphalt binder

Disclosed are asphalt binder compositions that contain at least one sterol or stanol additive, or blends of sterols and stanol additives, wherein the sterol or stanol additive is derived from an animal waste or manure source such as swine manure. These sterol and stanol-based additives improve various rheological properties of the asphalt binder compositions showing reduced and/or mitigated aging characteristics.
