This invention also designs and builds multiple layers (two layers or more) of millable denture base or denture blocks or disks comprised of denture base or/and denture tooth materials to form final dental devices, such as partial and full dentures. A method for manufacturing a layered denture is provided. The invention provides a multiple layered denture base block (or disk) for milling a denture base. The invention also provides a multiple layered denture block (or disk) for milling a denture. Highly shape adjustable or shape memory polymer layer(s) may be used in these multiple layered forms. Different layer of material has different mechanical and physical properties to meet different need, which provide added benefits to the patients, dental professional and dental laboratory.

Composite pillar structures, in particular for adhesion to soft and rough surfaces, include in the longitudinal direction at least one region with lower elasticity modulus and at least one region with higher elasticity modulus. The region with lower elasticity modulus preferably includes an end face, wherein the two regions adjoin one another.

The present disclosure relates to insulation systems. The teachings thereof may be embodied in an insulation system for an electrical machine. For example, an insulation system may comprise: solid insulation materials; an impregnating resin having oxirane functionalities; a depot accelerator distributed throughout the solid insulation materials; and a catalyst for initiating hardening of the impregnating resin, wherein the catalyst is at least partly in gaseous form under hardening conditions.

A tile made of hard objects, such as stones, that are enclosed in epoxy and a method to fabricate such tiles are disclosed. The method includes placing a predetermined volume of sand of a predetermined coarseness into a mold of a predetermined size; leveling the sand in the mold; placing a first predetermined volume of stones of a first predetermined size range over the sand in the mold; placing a second predetermined volume of stones of a second predetermined size range over the sand in the mold; pouring a predetermined amount of self-leveling epoxy material over the stones and sand; and curing the epoxy material. A top coat is next applied to ensure that the bigger stones that sit proud of the epoxy are wetted to give the brilliant color of wet stones as seen at the lakeshore.

A method for manufacturing a contact lens having a multilayer structure using a mold, includes: (a) charging a first polymerizing composition into a space formed by combining a first mold with a second mold, and polymerizing a first semi product having a thinner thickness and a smaller outer diameter than those of a contact lens immediately before being removed from the molds after all polymerizing processes; (b) opening the first and second molds; and (c) charging a second polymerizing composition into a space formed by combining a third mold with one of the first and second mold, the first semi product fixed onto the one of the first and second molds, and polymerizing the second polymerizing composition.

The present disclosure relates to a method of manufacturing an engineered flooring product comprising a core layer. The method provides the steps of: (a) mixing a hydrate compound, one or more stabilizing agents, and water in a mixer, forming a raw material slurry; (b) spreading a first layer of the raw material slurry onto a cull plate; (c) curing the first layer of raw material slurry; (d) after step (c), releasing the cured first layer of raw material slurry from the cull plate; (e) after step (d), trimming the cured first layer of raw material slurry released from the cull plate; and, (f) after step (e), cooling the cured first layer of raw material slurry released from the cull plate for at least about 24 hours at a temperature ranging from about I0 C-30 C thereby forming the engineered flooring product.

High quality flexible optical mirrors (in a single or multi-layer implementation) are fabricated from polymer matrix composite material(s) by replication, cast-spinning, and 3-D printing processes. These mirrors are suited as controllable mirrors for different applications including telescope mirrors. The mirrors made from smart materials (carbon nanotubes in epoxy) attain controlled properties that may be changed by application of external stimuli, including stress, temperature, moisture, electric and magnetic fields, as well as electromagnetic fields. When formed with non-ferrous metal particles embedded in epoxy, the mirrors are suited for cryogenic operations. The mirrors formed with the ferromagnetic/epoxy material can be deformed and steered by magnetic or electromagnetic fields.

A process of making a tack-free gel is disclosed comprising the steps of providing a mold defining a mold cavity, the mold cavity comprising a plastic material; pouring or injecting a molten gel having a high molding temperature into the mold cavity; and forming the tack-free gel as a thin layer of plastic of the mold cavity is melted over the gel. The forming step further comprises cooling the gel from the molten state to a solidified state. The melting temperature of the plastic material is lower than the molding temperature of the gel; and the higher the temperature differential, the greater the melting of the plastic material and the thicker the layer of the plastic material on the surface of the gel. The mold may be formed of low-density polyethylene (LDPE).

The present invention relates to a method of fabricating an array of optical lens elements, comprising: providing a first mold having a plurality of recesses; applying a first polymer liquid in said plurality of recesses; providing a first contact shaping substrate; contacting said first contact shaping substrate with said first polymer liquid in said plurality of recesses, wherein said contact between said first contact shaping substrate and said first polymer liquid results in a deformation of the contour configuration of said first polymer liquid facing away from said plurality of recesses; curing said first polymer liquid to form an array of optical lens elements.
