20150144480 | INDUSTRIAL MICROWAVE ULTRASONIC REACTOR - An industrial microwave ultrasonic reactor has an inner wall liner. A microwave generation device is formed by microwave units distributed on an outer sidewall, or by a microwave pipe disposed outside the reactor and microwave units distributed on the microwave pipe. One end of the microwave pipe communicates with the bottom of the reactor via a connection pipe I, and the other end communicates with the top via a return pipe. A shield is disposed outside the microwave generation device to separate the microwave units from the outside, and a heat removal device is disposed outside the shield. An ultrasonic wave generation device is formed by 10 to 30 sets of ultrasonic pulse units disposed at intervals along the outer sidewall. Each set has 10 to 50 members distributed along the circumferential direction of the reactor. A stirring shaft is fixed below a stirring motor and extends into the reactor. | 05-28-2015 |

20140099294 | Biotherapy for Pain - The present invention is directed to analgesic Clostridial neurotoxin derivatives comprising polypeptides having a long-lasting SNARE protein-selective endopeptidase activity. These derivatives selectively bind to and are internalized by non-neuronal cells secreting cytokines or sensory neurons in preference to motor neurons or autonomic neurons. The invention is also directed to nucleic acid constructs encoding such polypeptides, and methods of making such derivatives and nucleic acid constructs, and methods of treating pain, such as chronic pain, by administering such derivatives to a patient suffering from, or at risk of suffering from such pain. | 04-10-2014 |

20110318088 | CABLE HEAD FOR PETROLEUM LOGGING - A cable head for petroleum logging includes a first connector and a second connector; there is a tension rod between the first connector and the second connector; a first piston, a second piston and a third piston are successively provided on the upper part, the middle part and the lower part of the first connector; the diameter of the second piston is greater than the diameters of the first and third piston respectively; the first and second piston are sealed and mounted inside a first cylinder; the third piston is sealed and mounted inside a second cylinder; the lower part of the second cylinder is fixedly connected with the second connector; a balance cavity is formed between the lower end face of the second piston and the upper end face of the second cylinder when the lower end face of the first cylinder is contacted with the upper end face of second cylinder; the balance cavity communicates with the external by a passage on the first or second cylinder; an axial projected area of the lower end face of the second piston is equal to a cross section area of the first piston. When the cable head is stuck in the well in use, the logging cable can be disconnected by breaking the tension rod, thus it is no need to overcome the pressure of fluid in the deep well. | 12-29-2011 |
