CELLULOSE-BASED INSULATION AND METHODS OF MAKING THE SAME
20250019964 · 2025-01-16 · ·

A method for making cellulose-based fire resistant insulation. The insulation includes a plurality of superstructures that establish voids in the insulation. The insulation may be blown in place while the superstructures maintain the void portion of the insulation. The insulation is made with fiber residuals, either alone or in combination with other cellulosic materials. The method of making the insulation includes the steps of treating the cellulosic materials with a fire retardancy chemical or chemicals and creating bonds between the fibers to form the superstructures.

TOOLS COMPRISING REPEATING STRUCTURES FORMED USING ADDITIVE MANUFACTURING PROCESSES

In some examples, a tool for manufacturing parts includes a body formed using an additive manufacturing process, where the body includes a plurality of repeating structures, and where the plurality of repeating structures include a first subset of repeating structures each having a first physical property as specified by a digital representation of the tool used in the additive manufacturing process, and a second subset of repeating structures each having a different second physical property as specified by the digital representation of the tool used in the additive manufacturing process.

LIGHTWEIGHT DOME-SHAPED CASKET LID AND METHOD OF MANUFACTURE
20170319417 · 2017-11-09 ·

A novel technique for the fabrication of a casket dome lid from, for example, Smooth-One-Side (S1S) hardboard is disclosed. The invention is also directed to the fabrication of a casket lid which has a domed configuration both in the lateral and longitudinal directions of the lid. The method comprises the steps of providing a lid blank having a first end, second end, and a central region; providing a pair of diagonal voids oriented at corners of the first end of said blank and extending inward toward the central region; placing the lid blank in a vacuum fixture; and flexing the lid blank into a domed configuration via the vacuum fixture, such that the blank is domed in both a longitudinal and a transverse direction.
