Abstract: The invention discloses a center lock structure, comprises a chassis, rotary sliding sleeve and a center rod, the top of the rotary sliding sleeve is circumferentially and slidely connected with the chassis; and the center rod is extended into the rotary sliding sleeve along the top of the chassis, an elastic member is provided at one side on the bottom of the center rod, the elastic member is exposed outside the center rod when there is no external force, and the elastic member is concealed in the center rod when squeezed by an external force; in the invention, by the center rod, upper and lower rotary sliding sleeve, through holes and the accommodating grooves for pressing or releasing the elastic member, the structure can be unlocked by rotation and pull-down.

Abstract: The present disclosure provides a method for two-phase partitioning production of a medium-chain fatty acid (MCFA) by dry anaerobic digestion. In the present disclosure, due to a slow heat transfer of the dry anaerobic digestion, a same dry anaerobic digestion device is naturally divided into two phases, and the MCFA is synthesized while producing electron acceptors and electron donors in the same dry anaerobic digestion device. Meanwhile, the dry anaerobic digestion device is provided with a high-efficiency decomposing microbial inoculant on an upper part and inoculated with sludge having a carbon chain extension function on a lower part. In this way, a material residence time is regulated, and cycles of hydrolytic acidification and carbon chain extension are shortened, thereby achieving the high-value conversion of agricultural waste while increasing a conversion rate of organic acids in the dry anaerobic digestion.

Abstract: A light bulb includes a housing, an illuminating component, a driving circuit board, a light transmitting component and a lens. The housing has a circumferential opening and a cavity chamber therein. The illuminating component is disposed within the cavity chamber. The driving circuit board is disposed inside the cavity chamber. The driving circuit board is also electrically coupled to the illuminating component. In addition, the driving circuit board drives the illuminating component while being powered up. The light transmitting component is disposed within the cavity chamber and affixed to the illuminating component. The light transmitting component includes a plurality of transmitting microstructures on its surface that uniformly distribute lights emitted from the illuminating component along an axial direction of the light bulb. The lens is disposed within the cavity chamber. The lens also focuses the uniformly distributed lights on a predetermined range along the axial direction of the light bulb.

Abstract: A method for making molecular sieves comprising silicoaluminophosphate 44 (SAPO-44) or substantially pure SAPO-44 and a method for using the molecular sieves so prepared for oxygenate conversions to olefins.

Abstract: A rescuing helmet assembly comprising a helmet body and a lining helmet is provided. The helmet body is provided with a spot light and the lining helmet is provided with copper tubing for storing oxygen. A light switch and an oxygen switch are disposed external of the helmet body and can be triggered on when a protecting face mask is moved downward. Accordingly, the spot light is triggered on and the oxygen is supplied. When a fire accident has occurred, the user may readily wear the rescuing helmet assembly to prevent being choked by the smoke. The light beam emitted from the spot light may readily help the user find a way out or it may serve as a target which can be readily spotted by firemen. The chance of being rescued is considerably increased.
