摘要： A method of treating a flexible multi-layer member exhibiting a glass transition temperature and including a surface layer, the method composed of: moving the member through a member path including: a contact zone defined by contact of the member with an arcuate surface including a curved contact zone region; a pre-contact member path before the contact zone; and a post-contact member path after the contact zone; heating sequentially each portion of the surface layer such that each of the heated surface layer portions has a temperature above the glass transition temperature while in the curved contact zone region; and cooling sequentially each of the heated surface layer portions while in the contact zone such that the temperature of each of the heated surface layer portions falls to below the glass transition temperature prior to each of the heated surface layer portions exiting the curved contact zone region, thereby defining a cooling region, wherein the heating is accomplished in a heating region encompassing any part or all of the contact zone outside the cooling region and a portion of the pre-contact member path adjacent the contact zone.

摘要： A ceramic composition (sample) includes CaBi4Ti4O15 or another compound having a layered perovskite crystal structures and exhibiting ferroelectricity at ordinary temperature. The ceramic composition (sample) is then heated to a temperature higher than the melting point of the ceramic composition to make the ceramic composition molten or semi-molten. The ceramic composition is then annealed and solidified to yield a grain oriented ceramic (porcelain). This process can produce grain oriented ceramics from ceramic compositions mainly containing a compound having a layered perovskite crystal structure, and can improve electromechanical coefficients of piezoelectric ceramics containing a compound having a layered perovskite crystal structure.

摘要： A method of net-shaping using aerogel materials is provided by first forming a sol, aging the sol to form a gel, with the gel having a fluid component and having been formed into a medium selected from the group consisting of a powder, bulk material, or granular aerobeads, derivatizing the surface of the gel to render the surface unreactive toward further condensation, removing a portion of the fluid component of the final shaped gel to form a partially dried medium, placing the medium into a cavity, wherein the volume of said medium is less that the volume of the cavity, and removing a portion of the fluid component of the medium. The removal, such as by heating at a temperature of approximately less than 50° C., applying a vacuum, or both, causes the volume of the medium to increase and to form a solid aerogel. The material can be easily removed by exposing the material to a solvent, thereby reducing the volume of the material. In another embodiment, the gel is derivatized and then formed into a shaped medium, where subsequent drying reduces the volume of the shaped medium, forming a net-shaping material. Upon further drying, the material increases in volume to fill a cavity. The present invention is both a method of net-shaping and the material produced by the method.

摘要： A method for removing supports from a three-dimensional objected formed by selective deposition modeling. The three-dimensional object is formed from a curable phase change material and the supports are formed from a non-curable phase change material. The curable phase change material contains between about 5% to about 25% of a non-reactive wax in order to achieve the desired phase change characteristics of the material. When removing the supports with heat, discoloration undesirably occurs in the three-dimensional object as the non-reactive wax migrates within the object. The method prevents wax migration by cooling the object slowly past the freezing point of the build material such that a temperature differential no greater than about 5° C. is present within the object. With the preferred build material having a freezing point of about 49.5° C., this is achieved by lowering the temperature between about 62° C. to about 52° C. over a period of between about 5 to about 10 minutes so that the temperature of the regions of the object remain substantially equal as the freezing point is crossed during cooling.

摘要： In the production of spiral-shaped heating elements, a device winds an oblong base material onto a mandrel while forming a spiral with the base material and equips the ends of the spiral with contacts for electrical connection. The device includes a feeding device for supplying the mandrel, onto whose casing surface the base material is wound in a spiral shape, with the oblong base material. In order to carry out a method for the production of a spiral-shaped heating element made of material containing carbon fibers, the method is as follows: utilize a base material that comprises carbon fibers which have been embedded into IBM a thermoplastic embedding compound, heat the base material to a temperature at which the embedding compound softens, wind the softened base material onto the mandrel while forming the spiral, and set the spiral shape by removing the embedding compound. On the device used to carry out the method, there is included a heating device which affects the base material in the area of the casing surface of the mandrel and can be adjusted to a temperature above the softening temperature of the embedding compound. The invented heating element, which distinguished itself due to its low thermal inertia and high radiation capacity at comparatively low temperatures, is formed in the shape of a spiral having a series of carbon fibers that are connected with each other.

摘要： A system for producing blocks of open-cell, flexible polyurethane foam material and for conditioning each freshly-manufactured block to impart thereto optimal flexible foam properties. The system includes means to pour the flowable constituent of the foam material to be manufactured into a production station at the inlet of a conveyor, the constituents interacting to create on the conveyor a block of open-cell flexible foam material which is then wrapped in a plastic film casing that exposes the leading and trailing end of the block so that the encased block is open ended. The conveyor transports the wrapped block toward the rear end of a gate in a conditioning station having a port therein whose front end is coupled by an air duct to a suction fan. When the exposed leading end of the wrapped block abuts the rear end of the gate, the suction fan draws ambient air into the block through its open trailing end and acts to evacuate from the wrapped block fumes, particulate matter entrained therein and other contaminants generated by an initial exothermic reaction in the block.
