20120020841 | BLADED REACTOR FOR THE PYROLYSIS OF HYDROCARBONS - A bladed reactor for the pyrolysis of hydrocarbons comprises a rotor with working blades that form an axial bladed cascade, a fixed toroidal collar that adjoins the ends of said blades, and a housing that surrounds the collar and the periphery of the rotor in such a manner that a passage with an annular meridional section is formed. One or more barriers are mounted in the passage, an inlet orifice being arranged after each barrier and an outlet orifice being arranged in front of each barrier. Nozzle blades forming a nozzle cascade are mounted on the inlet side of the rotor cascade, and diffuser blades forming a diffuser cascade are mounted on the outlet side of the rotor cascade. There is a space without blades between the outlet of the diffuser cascade and the inlet of the nozzle cascade. The group of nozzle blades arranged directly after each barrier can be separated off from the remaining nozzle blades by a diaphragm such that a channel is formed connecting the corresponding inlet orifice to said group of blades, which makes it easier to start up the reactor. | 01-26-2012 |

20120146553 | Blumlein Assembly with Solid State Switch - A blumlein assembly incorporating a solid-state switch is presented. In the exemplary embodiment, a semiconductor switch is placed between first and second conducting strips, with dielectric material filling in the space between the strips on either side of the switch. A third conductive strip, parallel to the other two strips, is separated from the middle one of the strips by another dielectric layer. Rather than having the switch attach directly to the dielectric material on either side, a holder or carrier structure is used, which may be formed of several pieces or of a monolithic structure. The holder is formed of a material whose dielectric constant is closer to that of the switch than the dielectric material on either side, but whose boundary with the dielectric on either side has at least a portion that extends in a non-orthogonal direction with respect to the conducting strips. The arrangement allows the structure to withstand higher electric field levels without breakdown. The exemplary switch is light activated and the holder structure also includes ferrules on either side of the holder, by which optic fibers can be optically coupled with the switch. The switch extends to either side beyond the conductive strips, so that the ferrules are not placed between these strips to again allow for the use of higher field values. | 06-14-2012 |
20130181637 | High Voltage RF Opto-Electric Multiplier for Charge Particle Accelerations - Circuitry is presented for use in the pulse-forming lines of compact linear accelerators of charged particles. This presents devices that can provide high-voltage radio-frequency pulses in the range of from a few volts to megavolts for charged particle accelerators. The devices can use as input an external charge voltage and an optical pulse to create output RF pulses with a peak voltage that is increased over the input voltage. The exemplary embodiment presents a circuit of pulse forming lines for compact linear accelerator that includes an opto-switch and RF transmission lines that form a pulse shaper and a ladder-like pulse multiplier unit, with or without an output shaper. | 07-18-2013 |
20140084815 | Layered Cluster High Voltage RF Opto-Electric Multiplier for Charged Particle Accelerators - Circuitry is presented that can provide high-voltage radio-frequency pulses in the range of from a few volts to megavolts for charged particle accelerators. Individual pulse forming sections, such as transmission line transformers (TLTs) or blumleins, are formed in clusters. The pulse forming sections of each cluster are connected in series and have transmission lines ending in a ring structure. Multiple clusters can then be arranged with their rings aligned along the axis of the accelerator. | 03-27-2014 |

20090142364 | Method for finding novel peptide immunostimulatory adjuvants, compositions and methods of use - The invention describes production of an adjuvant with biological activities related to N-acetylglucosaminyl-β1-4-N-acetylmuramyl-alanyl-D-isoglutamine (GMDP), a commonly used enhancer of the immune response. It was found in the present invention that the drawbacks of GMDP can be avoided by replacing it with a peptide that does not have any direct structural relationship with GMDP. | 06-04-2009 |
