摘要:
A materials system and methods are provided to enable the formation of articles by three-dimensional printing. The materials system includes an absorbent particulate filler that facilitates absorption of infiltrants, thereby allowing the accurate definition of articles with enhanced mechanical and structural characteristics. The methods include the use of phase-change materials to bind a powder, as well as the formation of support structures to improve the control of the shape of the articles.

A materials system and method is provided to enable the formation of articles by three-dimensional printing. The materials system includes thermoplastic particulate filler material that allows the accurate definition of articles that are strong without being brittle.
摘要:
A three-dimensional printing materials system and method can produce both appearance models and small numbers of functional parts in an office environment. The method can include building cross-sectional portions of a three-dimensional article, and assembling the individual cross-sectional areas in a layer-wise fashion to form a final article. The individual cross-sectional areas can be built by using an ink-jet printhead to deliver an aqueous solvent or binder to an adhesive particulate mixture, causing the particles of the mixture to adhere together, and to previous cross-sectional areas. The binder can include at least one of nonaqueous organic monomeric compound, anionically ionizable polymer, cationic polymer, polymer, waterborne colloid, or inorganic solute.
摘要:
The present invention is directed to three-dimensional printing material systems and method, and an article made therefrom. The method of the present invention includes building cross-sectional portions of a three-dimensional article, and assembling the individual cross-sectional areas in a layer-wise fashion to form a final article. The individual cross-sectional areas are built by using an ink-jet printhead to deliver a fluid to a particulate material that includes particulate material.

A hair accessory for attaching hair extensions to a person's hair includes a clip having front and back members pivotally connected with a hinge. Each member has inner and outer sides. One or more magnets are fixed with the front and back members of the clip, aligned with one another to maintain the clip in a closed position magnetically. The hair extensions are fixed with the outer side of the members. In use with the clip moved from an open position to the closed position about the person's hair, the hair extensions hang downwardly to augment the appearance of the person. The person's hair not within the clip can be combed over the clip to hide the clip from casual view.

A garment for outdoor wear, having a central portion adapted to fit about an adult's torso, the central portion comprising respective side panels; sleeves extending downwardly from the upper extremity of the central portion, to accommodate the arms of a person wearing the garment; and size-adjusting closures extending from the lower extremity of the central portion upwardly under the sleeves.
摘要:
A method for searching the contents of a memory device for a pen-based computer system, where the contents of the memory device are organized as one or more files, where each file contains records, and where a file has an associated "button" proved on a surface of the housing of the computer system. The method includes the ,steps of: receiving a find-command from a user; receiving a selection search string from the user; searching the records of each file in the memory device for the search string; making a list of target files and the number of hits in each file; displaying indicators showing a summary of the list; and processing a user input with the summary. All of the records in all of the files are searched. The number of hits for each file are displayed.
