Abstract: A versioned file system comprising network accessible storage is provided. Aspects of the system include globally locking files or groups of files so as to better control the stored files in the file system and to avoid problems associated with simultaneous remote access or conflicting multiple access requests for the same files. A method for operating, creating and using the global locks is also disclosed. A multiprotocol global lock can be provided for filing nodes that have multiple network protocols for generating local lock requests.

Abstract: An endodontic file (200) is provided particularly adapted for the removal of tooth structure, decayed or damaged nerve tissues or dentine material on the interior walls of a root canal or dentine and/or enamel from the external tooth wall. The endodontic instrument includes a shaft (202) having a shank portion (204) and a generally elongated working portion (206). The working portion preferably includes cutting or abrading features (232) adapted upon rotation and/or reciprocation of the instrument to cut, abrade or remove tissue from the interior walls of a root canal or dentine and/or enamel from the external tooth wall. The working portion extends from a proximal end (207) adjacent the shank portion to a distal end (208) terminating at a tip (250).

Abstract: A machine and method for drafting a patent application has a keyboard, mouse, display, printer, and a computer for receiving and transmitting data. The computer requests and stores information regarding the invention including, if appropriate: 1) qualities and benefits (QAB) of the invention over the prior technology; 2) primary elements (PE) of the invention that define the invention apart form prior technology; 3) secondary elements (SE) of the invention that may be important but not necessary to define over the prior technology; and 4) substitute elements (SUB) of the invention that may substituted or modified in an effort to avoid the primary and secondary elements but not depart from the invention.

Abstract: This disclosure relates to dielectric chaff materials or fibers which are small in character for packing and expandable on release to produce clouds of great cross section. Polymer materials are treated chemically and/or irradiated with nuclear or electronic radiation which partially decomposes the polymer. Upon release, the polymer is heated to create gas bubbles from within which expand the dielectric fibers to change the density and shape of the dielectric.

Abstract: The invention provides a continuous process for producing a pure grade of acrylic acid having residual aldehyde levels under 10 parts per million. The process applies two groups of amines sequentially and continuously in selectively reducing acrolein and furfural and may be advantageously conducted in the presence of maleic acid and maleic anhydride impurities.

Abstract: A process for the preparation of an .alpha.,.beta.-unsaturated C.sub.3 -C.sub.6 carboxylic acid of greater than 98% purity, which combines fractional distillation and melt crystallization procedures.

Abstract: Frequency and other characteristics of energy contained in a region of the lectromagnetic or acoustic spectrum under examination is determined by subdividing the region, examining each subdivision for energy content, and then further subdividing and examining those subdivisions exceeding a threshold energy. This process is continued until the bandwidth of the last subdivision is equal to the desired frequency resolution.
