  • Fastener having a tab in the contact region
    Patent number: 6921237
    Abstract: This invention relates to a fastener, which expands by the insertion of an expanding member, preferably a screw. The fastener comprises a substantially flat head and two expandable legs. The head has an upper side and a lower side, preferably separated by a gap. The head has also a hole on the upper side in which the screw engages. Further, the screw engages in other locations of a critical portion of the rest of the body of the fastener, thereby increasing considerably the prevailing torque required to render the screw loose, the pulling force required to break the fastener or otherwise pull the screw out of the engageable hole of the upper side of the head, as well as the stripping torque.

  • PREPARATION OF CAPSULES
    Publication number: 20050156340
    Abstract: Prior art processes for producing protein-based capsules (for example, capsules for use in electrophoretic media) tend to be wasteful because they produce many capsules outside the desired size range, which is typically about 20 to 50 ?m. Capsule size distribution and yields can be improved by either (a) emulsifying a water-immiscible phase in a preformed coacervate of the protein; or (b) using a limited coalescence process with colloidal alumina as the surface-active particulate material.

    Patent number: 6920270
    Abstract: A method for determining at least one parameter of a periodic spin function ?(z) with period p, to be applied to an optical fiber along its length z during a drawing process. At least one parameter is selected so that (I) where ?1 is about 0.05 and y1 is the first of the three components y1(z), y2(z), y3(z) of a periodic function y(z) of period p such that (II) where LB is an expected beat length of said optical fiber and ?(z) is the derivative of the spin function ?(z) with respect to the length z. The method is effective for substantially reducing the PMD of optical fibers drawn when applying a spin function.

  • Chart view for reusable data markup language
    Patent number: 6920608
    Abstract: Methods and systems provide a “chart view” for a markup language referred to as Reusable Data Markup Language (“RDML”). Generally, a chart view comprises the components necessary for automatically manipulating and displaying a graphical display of numerical data contained in RDML markup documents. RDML is a markup language, such as the Hypertext Markup Language (“HTML”) or the Extensible Markup Language (“XML”). Generally, RDML facilitates the browsing and manipulation of numbers, as opposed to text as in HTML, and does so by requiring attributes describing the meaning of the numbers to be attached to the numbers. Upon receiving RDML markup documents, the chart view transforms, formats, manipulates and displays data stored in the markup documents using the attributes describing the meaning of the data.
