  • Patent number: 10655038
    Abstract: A method of making magnetizable abrasive particles includes providing a slurry layer disposed on a substrate. The slurry layer has an exposed surface and comprises magnetic particles, a binder precursor, and a liquid vehicle. Abrasive particles are electrostatically contacted with the slurry layer such that they are aligned substantially oriented perpendicular to the surface of the substrate, and are partially embedded within the slurry layer. The liquid vehicle is at least partially removed from the slurry layer and the binder precursor is converted into a binder to provide a magnetizable layer comprising the magnetic particles partially embedded in the binder. The magnetizable abrasive particles are separated from the releasable substrate. Each magnetizable abrasive particle respectively comprises a portion of the magnetizable layer disposed on a portion of an abrasive particle.

  • Publication number: 20200139612
    Abstract: The method includes stretching a thermoplastic layer so that it plastically deforms and decreases in width and subsequently laminating the thermoplastic layer to a substrate to make the laminate. The stretching and laminating are completed in-line. The thermoplastic layer has a first surface and a second surface opposite the first surface, with the first surface of the thermoplastic layer bearing a plurality of male fastening elements. The second surface of the thermoplastic layer is laminated to the substrate. In some cases, the thermoplastic layer decreases in width by at least 25 percent, and after the stretching, the thermoplastic layer has a width of up to 60 millimeters. In some cases, stretching is carried out by first and second rolls, and the second roll is faster than the first roll. The thermoplastic layer is typically not directed onto a third roll slower than the second roll before laminating.

  • Publication number: 20190364870
    Abstract: A flying insect station for attracting and killing insects on the exterior and interior of a structure is disclosed. The flying insect station includes features for attracting and killing files within a shortened window of time, preferably within one hour. The station includes in one aspect a surface being substantially dark in color and substantially reflective in nature to provide a facade of an opening. Suppression means such as a pesticide is included on one or more of the surfaces of the station for killing flying insects staging on the surface(s). An attractant may be used to provide a plume of attractant around surfaces of the housing to attract and lure flying insects to stage about a reflective surface.

  • Publication number: 20190359899
    Abstract: Systems and methods are provided for hydroconversion of a heavy oil feed under slurry hydroprocessing conditions and/or solvent assisted hydroprocessing conditions. The systems and methods for slurry hydroconversion can include the use of a configuration that can allow for improved separation of catalyst particles from the slurry hydroprocessing effluent. In addition to allowing for improved catalyst recycle, an amount of fines in the slurry hydroconversion effluent can be reduced or minimized. This can facilitate further processing or handling of any “pitch” generated during the slurry hydroconversion. The systems and methods for solvent assisted hydroprocessing can include processing of a heavy oil feed in conjunction with a high solvency dispersive power crude.

  • Publication number: 20190351531
    Abstract: A method of transferring a shaped particle to a substrate includes providing a scrim of at least two elongate strands periodically joined together at flexible bond regions to form an array of apertures between the strands. The scrim is extended along at least one direction to increase the minimum dimension of the apertures. Shaped particles are applied to the extended scrim and at least a portion of the shaped particles enter in at least some of the apertures therein. The extended scrim is relaxed and frictionally retains the particles between the elongate strands. The particle loaded scrim is extended along at least one direction to release and transfer the shaped particles to the substrate in a predetermined orientation.
