20150157805 | RETRACTABLE SELF-DESTRUCTING SAFETY SYRINGE WITH PRE-ATTACHED NEEDLE - A retractable self-destructing safety syringe with pre-attached needle including a barrel, an inner needle base disposed in a barrel neck at an end of the barrel body, and an elastic engagement mechanism formed between the barrel neck and the inner needle base is provided. An asymmetric elastic locking member having an elastic function is disposed at the end of the plunger, with which a sleeve-type retractable locking member on the needle base can be interlocked by the elastic function. After being retracted into the barrel body, the needle base together with the needle will be forced to deflect to one side under an asymmetric force, and the needle therefore will be forced to incline in a direction nearly a 45 degree angle toward to one side of the inner wall of the barrel and is blocked by the barrel neck, so that the needle and the needle base could not be pushed out the barrel neck again and self-destruction of the syringe is truly achieved. The asymmetric elastic locking member is a plastic hook which is formed with the plunger body by one-time molding process. | 06-11-2015 |

20160115783 | Data Transmission System and Method for Transmission of Downhole Measurement-While-Drilling Data to Ground - Disclosed is a data transmission system and a method for transmission of downhole measurement data to the ground. The system includes a drill string mounted with a logging while drilling measurement tool, and a throw while drilling section, which accommodates a micromemory. The throw while drilling section includes a housing which is mounted outside of the drill string as a sleeve to form a clearance space therebetween; a control circuit; and a wireless transceiver. The throw while drilling section releases, under function of a micromemory release instruction transmitted by the control circuit, the micromemory loaded with the downhole measurement data to the ground. | 04-28-2016 |
