  • PLATE PROCESSING
    Publication number: 20120264038
    Abstract: A method of processing a linked series of metallic plates, in which each plate (9) is connected to an adjacent plate along adjoining edges (8), the method comprising: providing the series of plates as a first fan-folded stack of plates (1); drawing the plates in sequence from the stack; applying a surface treatment to one or more of the plates; and stacking the plates in reverse order to form a second fan-folded stack of plates (5).

  • Synthesis of long-chain polyunsaturated fatty acids by recombinant cells
    Patent number: 8288572
    Abstract: The present invention relates to methods of synthesizing long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid, in recombinant cells such as yeast or plant cells. Also provided are recombinant cells or plants which produce long-chain polyunsaturated fatty acids. Furthermore, the present invention relates to a group of new enzymes which possess desaturase or elongase activity that can be used in methods of synthesizing long-chain polyunsaturated fatty acids.

  • Wavelength Assignment In An Optical WDM Network
    Publication number: 20120251103
    Abstract: The path selection and wavelength assignment to a selected path are performed by mapping the wavelength reach to the demand distribution (agile reach) resulting in a 50-60% increase in the network reach. The network reach is further increased (about 2.2 times) when on-line measured performance data are used for path selection and wavelength assignment. The connections may be engineered/upgraded individually, by optimizing the parameters of the entire path or of a regenerator section of the respective path. The upgrades include changing the wavelength, adjusting the parameters of the regenerator section, controlling the launch powers, mapping a certain transmitter and/or receiver to the respective wavelength, selecting the wavelengths on a certain link so as to reduce cross-talk, increasing wavelength spacing, etc.

  • Water management in fuel cells
    Patent number: 8277998
    Abstract: An electrochemical fuel cell having an anode, an ion transfer membrane and a cathode has liquid water delivered to the fluid flow channels within the cathode so as to maintain a relative humidity of 100% throughout the fluid flow channels. A calibration method and apparatus is described for determining an optimum quantity or range of quantities of liquid water to be delivered to the cathode fluid flow channels under varying operating conditions. An operating method and apparatus is described that ensures an optimum quantity of liquid water is delivered to the cathode fluid flow channels under varying operating conditions.

  • LIQUID LEVEL SENSOR
    Publication number: 20120239316
    Abstract: A liquid level sensing system, including: an input acoustic waveguide, and an output acoustic waveguide, positioned extending into liquid to be sensed; the input waveguide being arranged to receive acoustic energy; an acoustic sensor attached to the output waveguide for sensing acoustic energy at the output waveguide that has been transferred from the input waveguide to the output waveguide by being acoustically coupled by the liquid; and a processor arranged to process timing characteristics of the sensed acoustic energy to determine a measure of the liquid level.

  • FAN ASSEMBLY
    Publication number: 20120230658
    Abstract: A bladeless fan assembly for creating an air current includes a nozzle mounted on a base housing a device for creating an air flow. The nozzle includes an interior passage for receiving the air flow and a mouth for emitting the air flow. The nozzle defines, and extends about, an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The nozzle also includes a heater for heating the air flow upstream of the mouth.

  • SYSTEM AND METHOD FOR PARAMETER ESTIMATION IN BIOLOGICAL PROCESSES
    Publication number: 20120232804
    Abstract: A method of measuring a biological process, the method including the steps of: (a) determining a probability density function for a series of repeated measurements of the biological process; (b) approximating the probability density function utilising a parametric formula; (c) determining a maximum likelihood estimator for the parametric formulation of the probability density function; and (d) utilising the maximum likelihood estimator for subsequent measurements of the biological process.
