Abstract: An illustrative example embodiment of a fastener includes a pin having a head and a tail opposite the head. The tail includes a first crest, a second crest and a groove between the first and second crests. The first crest includes a surface on at least one side of the first crest having a first profile. The second crest includes a surface on at least one side of the second crest having a second profile. The second profile is different than the first profile. A pitch between a peak of the first crest and a peak of the second crest is different than a pitch between a root of the first crest and a root of the second crest.

Abstract: The present disclosure relates to a blind fastener and a method of installation thereof. The blind fastener comprises a sleeve and a mandrel. The sleeve comprises a first sleeve end, a second sleeve end, and a cavity extending from the first sleeve end to the second sleeve end. The mandrel is configured to be at least partially received by the cavity of the sleeve. The mandrel comprises a first mandrel end disposed adjacent to the first sleeve end and comprising an enlarged portion having a diameter greater than a diameter of the cavity, a second mandrel end comprising a pull region, and a shank region extending intermediate the first mandrel end and the second mandrel end. The pull region comprises an axial length no greater than four times a diameter of the shank region and is configured to be engaged by an installation tool.

Abstract: A Metric Information Network (MIN) with a plurality of Ground Control Points (GCPs) that are selected in an automated fashion. The GCP selection includes clustering algorithms as compared to prior art pair-wise matching algorithms. Further, the image processing that takes place in identifying interest points, clustering, and selecting tie points to be GCPs is all performed before the MIN is updated. By arranging for the processing to happen in this manner, the processing that is embarrassingly parallel (identifying interest points, clustering, and selecting tie points) can be performed in a distributed fashion across many computers and then the MIN can be updated.

Abstract: Provided is a method, system, and program for managing a multi-page document. A plurality of input files are received including digital representations of multiple pages of a document. The content of each entire page is represented in a first representation format. The entire page content is capable of including content of a first content type and second content type. For each page of the document represented in the input files, a determination is made of regions in the page including content of the second content type. Each determined region in the page is processed to generate the content for each region in a second representation format. The content of the entire page in the first representation format and the content of each region in the second representation format is added to at least one output file. The output file is then stored.

Abstract: Provided are a method, system, and program for processing graphics input. The graphics input may include a first and second types of graphics matter, such as line art and continuous tone. At least two data structures including representations of a same graphics matter are provided. An object is generated to include information on the data structures, including information relating the data structures. The object is then processed to produce graphics output including the graphics matter in the graphics input.

Abstract: An apparatus and method for providing a stream of molten metal from a metallic ingot wherein a quantity of the molten metal from the melted ingot is maintained at an established level within the chamber of the apparatus. It is further heated to an established temperature to then facilitate passage of the molten material through the apparatus's orifice.

Abstract: Superalloys containing uniform dispersions of at least 0.1 volume percent of a metal nitride improve qualities of superalloys. These superalloys are produced from superalloy powders by a nitridng process utilizing a controlled atmosphere for controlled times at controlled temperature. A nitriding temperature of at least 700.degree. C is required in order to produce effective amounts of nitride in practical lengths of time.
