  • Publication number: 20230357811
    Abstract: The present disclosure relates to a synthesis method of ?-nicotinamide mononucleotide (?-NMN) and an intermediate thereof. In the present disclosure, phospholipid metabolism enzymes phospholipase D (PLD) and phospholipase C (PLC) widely present in the biosphere are used as catalysts to prepare ?-NMN through two-step enzymolysis or one-pot synthesis; and an intermediate, namely phosphatidyl nicotinamide riboside (PNR), is obtained during the two-step enzymolysis. The present disclosure has simple reaction steps, low production cost, and environmental friendliness, and is suitable for large-scale industrial production.

  • Patent number: 8151861
    Abstract: A one-piece core-making technique used in producing railway truck bolsters and side frames, which includes the following steps: 1. After scraping the top of a core box, applying a shaped top mould (11), which is precisely located, from top to bottom. 2. Press or slightly hit the top mould (11) to make sure the top mould covers/caps the scraping surface. 3. Keep pressing to make sure that the flat scraping surface was pressed to a required curved shape, like the shape of the top mould (11). 4. Last, it will become a one-piece core with a partially integrated inner cavity section. The one-piece core made by this technique has a smooth surface. This technique also can improve the internal quality of the product and ease work intensity.

  • Publication number: 20100126687
    Abstract: An integer cored craftwork of lorry with swing bolster and sideframe includes: a baroque top mold (11) being located exactly from above to below as sand on the surface of core box being finished to blow. The top mold (11) is pressed for being buckled on the surface of blowing sand, then a definite journey of pressure quantity is finished downwards, so that the locally even surface of blowing sand is extruded to be a curved shape up to the mustard according to the shape of the baroque top mold (11). Finally the integer core forming a integrate lumen section of a cast is finished. It provides a slick surface of integer core while improving the inherent quality of cast and easing the work intension.
