Patent AT-E239817-T1 (AT)
Inventor: RYAN RICHARD J
IPC: B65H69/06

Abstract: A method for construction of a large diameter braided rope. The rope (10) is formed of high strength, low elongation synthetic fibers (16) which are twisted together at a twist factor in the range from about 125 to about 145 to form a plurality of comparatively small diameter yarns (14). The small diameter twisted yarns (14) are then braided together at a pick multiplier in the range from about 1.0 to about 2.0 so as to form a plurality of braided strands (12), and the strands (12), in turn, are braided together with a pick multiplier of about 2.0-3.6 so as to form the large diameter braided rope (10). The braiding of the strands (12) imparts a degree of coherence which permits a lower twist factor to be used in the yarns (14). This results in a significant increase in translational efficiency over conventional twisted-strand construction, by avoiding the over twisting of low elongation fibers which occurs when forming large diameter yarns. <IMAGE>

Granted: 2008-03-15
Abstract: The method involves allocating tasks originating in one or more client data processing nodes (C2) to the server processing nodes within a group of two or more server data processing nodes (S1-S4) for processing. A client data processing node with a task to assign first selects a server data processing node from the group that is the next node to be selected according to a predefined cyclical sequence. If the selected node declines the task, the client node randomly selects another server node and passes the task to it for processing if not declined. Independent claims are also included for a data processing system, a client data processing node and a computer-readable storage medium.

Abstract: A method for recovering substantially all carbon dioxide generated in a combustion process where the method comprises the following steps: a) a sweep gas is used to pick up oxygen on the permeate side of a mixed conducting membrane in a first stage which is capable of separating oxygen from a hot air stream fed to the retentate side of the membrane; b) the sweep gas containing oxygen is applied as oxidant in a combuster in the first stage where a carbon containing fuel is combusted; c) hot combustion products of step b) containing CO2, H2O and a low concentration of O2 is used as sweep gas in a membrane in a second stage downstream the combuster in step b); d) the concentration of oxygen in the sweep gas of step c) is increased in the membrane in the second stage (step c) to a sufficiently high level to be used as oxidant in the combuster in the second stage; e) and the steps c)-d) are repeated in one or more stages. Furthermore, the present invention relates to use of the method in different processes.

Abstract: A method of screening for fetal Down's syndrome is described. Screening marker levels are measured. These may be measurements of a biochemical marker in a maternal sample or measurements of a marker from an ultrasound scan. The marker levels are used to calculate a risk of Down's syndrome. Instead of using markers from a single stage of pregnancy, the method uses markers from two or more different stages of pregnancy, typically one being in the first and another being in second trimester. The method may be automated.

Abstract: An illumination system has separate components for extracting and directing light from a waveguide. The system eliminates the need to provide a light directing array (LDA) that is optically and physically coupled to the waveguide. It is more reliable and robust than previous illumination systems and virtually eliminates the failures associated illumination systems having laminated LDAs. Manufacturing costs are reduced and system performance and reliability are improved. The illumination system is inexpensive to construct, and operates in an efficient, reliable manner, affording extended service at low cost.
