  • Publication number: 20240318434
    Abstract: The present disclosure relates generally to siding, for example, suitable for use covering the exterior surface of a building. The present disclosure relates more particularly to a siding attachment accessory including an attachment platform having a front face and a rear face. The attachment accessory also includes at least one siding hanger extending forward from the front face of the attachment platform that is configured to hold a siding component. Each siding hanger of the attachment accessory includes a retaining arm having a proximal end attached to the front face of the attachment platform and a distal end spaced from the attachment platform.

  • Publication number: 20240226859
    Abstract: Process for the preparation of a catalyst by adding, clay, boehmite, a first silica to form a slurry, digesting the slurry with a monoprotic acid to a pH of less than 4, adding one or more zeolites, adding a rare earth component to the slurry and mixing, adjusting the slurry pH to below 4 with monoprotic acid, adding a second silica anywhere in the preceding steps, destabilizing the slurry by raising the pH, shaping and collecting the resulting catalyst, wherein the resulting catalyst has enhanced mesoporosity.

  • Publication number: 20080035861
    Abstract: A detector for use with a high pressure SEM, such as an ESEMĀ® environmental SEM from FEI Company, extends the effective detection space above the PLA, thereby increasing secondary signal amplification without increasing working distance or pressure. Embodiments can therefore provide improved resolution and can operate at lower gas pressures.
