摘要:
A method of forming a three-dimensional sculpture comprises the steps of providing a mold having a lining and a casting cavity, applying a powder to the mold lining, pouring a casting material into the casting cavity and curing the casting material to form a casting object, said powder being transferred to said casting object during curing of said casting material, and removing said casting object from said casting cavity to form a powder-laden three-dimensional sculpture.

This invention provides a process for rapid forming of a ceramic green part. It is based upon an effect, that nano-scaled oxide colloid can be gelled by drying. Slurry can be obtained by mixing the oxide colloid with ceramic powder and dissolved agent. After paving a slurry film on a platform, a focused high-energy beam scans over the surface of said slurry film; the irradiated portion will be dried and build a two-dimensional (2-D) pattern. In addition, another slurry film is paved on the finished 2-D pattern layer. The high-energy beam scans once more on slurry film locally; another 2-D pattern is built. This built pattern can be connected with the pattern beneath it. After multiple repetitions of this procedure a three-dimensional (3-D) part can be formed. Because gelling is an irreversible reaction, the gelled portion of slurry won't be dissolved in water. Therefore, the non-gelled slurry can be separated from the gelled ceramic green part by flushing.

A conductive seal that is formed on a first sealing surface by extruding an elastically curing material intermixed with conductive particles is in addition intermixed with magnetic particles. After applying the material to the first sealing surface, its cross section profile is expanded to an adjustable level towards a second sealing surface and/or sealing rims are molded to it by a magnetic force from an electromagnetic plate. The magnetic and conductive particles are preferably concentrated in the marginal sections, particularly due to magnetic forces that act on the sealing roving in the extrusion process.

An induction heating and control system and method have enhanced reliability and advanced performance features for use with induction cooking devices, such as induction heating ranges. Enhanced performance is facilitated via the use of an induction heating system which integrates voltage management, power management, thermal management, digital control sensing and regulation systems, and protection systems management.
摘要:
The present invention relates to the prevention and decrease of osteolysis produced by wear of the ultrahigh molecular weight polyethylene (UHMWPE). Methods are disclosed for the isolation of wear particles, preparation of implants exhibiting decreased wear in comparison to conventional UHMWPE and preparation of implants that cause decreased biological response in comparison to conventional UHMWPE. The implants created by these methods are also included in the present invention.

Disclosed is both a method and composition for forming a thermo-formable acoustical panel. The panel may be formed from multi-component polymer fibers or mono-filament polymer fibers dispersed in a mineral fiber batt. The polymer fibers are bound to the mineral fibers by the application of heat to form the acoustical panel.
摘要:
The present invention relates to film-forming compositions containing ethylene vinyl acetate copolymers with a vinyl acetate percentage that causes film-forming problems and processability problems and an alkylene bisoleamide which is used to enhance the film forming capabilities of these high VA content resins. The invention also relates to films prepared from these compositions and to coating compositions.
摘要:
A solid composition having a solid state film forming substance mixed with an inert carrier. The composition is heated in a vacuum chamber to evaporate the film forming substance by sublimation to form a molecular beam of amphiphilic molecules which settle on a substrate surface within the chamber and bond thereto while self-assembling into a thin film.
摘要:
An encapsulation method for sensitive composition is provided in which a film, in particular a plastic film, is laminated over the entire surface of an arrangement having a component mounted on a carrier in a flip chip construction. For additional sealing and mechanical stabilization, a plastic compound in liquid form is subsequently applied and hardened so as to surround the chip. Optionally, before the application of the plastic compound, the film can be removed in the area of structuring lines in such a way that the plastic compound can come into contact both with the carrier and with the chip surface.
摘要:
A method for manufacturing products, wherein a mass, comprising at least natural polymers such as starch, is brought into or through a mold and the mass in the mold is heated, such that this involves at least cross-linkage of the natural polymers, while of at least one first part of the product, the material composition is influenced such that the material properties of the relevant first part deviate from the material properties of parts adjoining said part.
