Title: Method for reducing the level of elemental sulfur and total sulfur in hydrocarbon streams
Inventor: FEIMER JOSEPH L
IPC: C10G19/02
Filed: 2005-07-12
Abstract: A method for reducing the level of elemental sulfur from sulfur-containing hydrocarbon streams as well as reducing the level of total sulfur in such streams. Preferred hydrocarbon streams include fuel streams such as naphtha streams that are transported through a pipeline.

Title: Adaptive optical equalization for chromatic and/or polarization mode dispersion compensation and joint opto-electronic equalizer architecture
Inventor: LEVEN ANDREAS BERTOLD
IPC: H04B3/06
Filed: 2005-08-05
Abstract: An adaptive optical parallel equalizer architecture is based on a controllable optical FIR filter device to realize an optical FIR (finite-impulse-response) filter including a plurality of coefficient taps in order to have independent control of each optical FIR filter coefficient. A unique adaptive opto-electronic LMS (least mean square) process is utilized to generate an electronic error signal utilized to control the plurality of parallel tap coefficients of the optical parallel equalizer. The electronic error signal is used as the optimization criterion because the electronic signal after photo-detection is needed to achieve any measurable performance in terms of bit error rate (BER). In a specific embodiment, the controllable optical parallel FIR  filter is realized by employing an optical vector modulator. The optical vector modulator is realized by splitting a supplied input optical signal into a plurality of parallel similar optical signals, controllably adjusting the phase and/or amplitude of each of the plurality of optical signals and delaying the resulting optical signals in a prescribed manner relative to one another. Then, the "delayed" signals are combined to yield the optical signal comprising the vector modulated input optical signal to be transmitted as an output. In one particular embodiment, both the phase and amplitude is adjusted of each of the plurality of parallel optical signals, and the error control signals for effecting the adjustments are generated in response to the optical FIR filter optical output signal utilizing the unique opto-electronic LMS process.

Title: A parallel concave and convex propeller blade for wind turbines
Inventor: VETTESE SHAROLYN
IPC: F03D1/06
Filed: 2005-09-16
Abstract: Propeller blades are normally designed according to their use, and airplane blades are different from wind turbine blades, and there are many variations in each. Most megawatt wind turbines have 3 blades that are wide at the hub and narrows to a point at its tip. They are also shaped to give a lift to the blade similar to the wing of a plane. The Parallel Concave and Convex blade, commercially labeled as the 'Sumara' propeller blade, is designed specifically for wind turbines equipped with the auxiliary propeller rotor on the same shaft as the primary rotor with a designated space of distance between the two. The 'Sumara' blade has the same width throughout, with a specific pitch and is designed to achieve a greater torque from its base to its tip. The leading edge to the wind is concave, providing least resistance to incoming air flow and the trailing edge is convex with a greater surface area. A semi-tubular beam rigidly supports the blade on the underside extending from the tip to its base, and converts to a stem that varies in length. The end of the stem is inserted into the receptor of the rotor and adjustment of the pitch is made by rotating the stem within the receptor of the rotor.

Title: A composition and its use for adminstration of mitomycin c in vivo for treating a multi-drug resistant tumor
Inventor: GABIZON ALBERTO
IPC: A61K9/127

Abstract: A method of operating a power controller that converts a line voltage to an RMS load voltage includes a soft start in which a conduction angle of a phase-control clipping circuit is gradually increased to a steady state value that defines the RMS  load voltage. The controller has a circuit with a time-based signal source that triggers conduction independently of line voltage magnitude and a transistor switch whose gate receives signals from the time-based signal source to trigger the circuit. When starting the power controller, a microcontroller increases the conduction angle of the phase-control clipping circuit in plural steps to provide the soft start.
