Abstract: Display panels having at least one suspended fibrous cathode containing an electron field emitter are disclosed. The fibrous cathode is supported by a substrate (10) containing two sets of parallel rows of crests and valleys. The first set of parallel crests (11) and valleys (12) provide the valleys along which the fibrous cathode is aligned. The second set of parallel crests (13) and valleys (14) is perpendicular to the first set. The valleys (14) provide the means for suspending the fibrous cathode. The display panels can be produced in large sizes while still maintaining high quality and efficiency.

Abstract: A system is provided for the safe transfer of large data files over an unreliable network link in which the connection can be interrupted for a long period of time. In the subject system, the sender sends a file with a unique signature which is recognized by the receiver, with the signature providing information as to file size. Upon the occasion of an interrupted communication over the link, the receive side waits for another connection. Upon the establishment of the connection, the receive side recognizes the signature of the file as the file which was being transmitted at the time of the interruption and requests blocks of data from the sender from the point at which the interruption occurred, with the point being established by the file size and the time of the interruption. The result is a restartable transfer of the transmission of information from the sender to receiver from the place where it left off, thus eliminating the annoyance of having to restart the transmission from the beginning.

Abstract: A mold core positioning device includes a cam member carried by a first mold segment that is configured to engage a cam follower carried by a second, cooperating mold segment. The cam follower is provided on a core slide to which an outwardly extending core member, such as a core pin, is connected.

Abstract: Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more aggregate materials, fibers, and optional admixtures in the correct proportions in order to form an article which has the desired performance criteria. The inorganically filled mixtures are molded to fashion a portion of the mixture into a form stable shape for the desired article. Once the article has obtained form stability, such as by heating to remove water by evaporation, the article is removed from the mold and allowed to harden to gain strength. The articles may have properties substantially similar to articles presently made from traditional materials like paper, paperboard, polystyrene, plastic, or metal. They have especial utility in the mass production of containers, particularly food and beverage containers.

Abstract: Yarns of melt-spun polymeric filaments are rapidly quenched, whereby the filaments are cooled by quenching gas that is accelerated along the threadline by being passed through a tube of reduced dimensions with the filaments before they emerge. In particular, a yarn is produced which has an elongation to break of about 100% or more. The yarn is comprised of filaments numbering from 25 to 150. The filaments are less than 4 denier per filament and makeup yarns having low denier spread.
