    摘要: An NMR teaching method and apparatus incorporating pieces representative of chemical fragments. Each piece has the number of sides corresponding to the number of bonds present around the central atom. Bonds to hydrogen are curved while bonding sides are flat. The presence of concavities and convex tabs on the bonding sides indicates bonding of the respective piece to a mating piece that causes splitting of the NMR peak. The shape of concavities on each piece is indicative of the chemical fragment of the respective piece while the shape of the convex tab of the respective piece is indicative of the chemical fragment of the mating piece. First and second bonding indicators can be used to replace the convex tabs. When presented with a spectrum, a student user can select the necessary pieces using data from the spectrum. Once selected, the student user can then assemble the pieces to determine the identity of the unknown molecule in the NMR spectrum.

    摘要: The present invention relates to a punch for punching a workpiece. In particular, the invention relates to a punch including a base to stably support the punch and a support member configured to accommodate and locate the workpiece in a punching position. The support member is preferably movably connected to the base and preferably includes at least one punch member configured and operably associated with the support portion to punch the workpiece in the punching position upon an actuation movement of the support member with respect to the base. Another embodiment of the present invention relates to a punch having a paper tray oriented at an angle with respect to the base to support a sufficient portion of a sheet of paper to prevent an unsupported portion from falling over and withdrawing from the support portion. In particular, the paper tray and punch mechanism are oriented to expel paper chips such that the chips are visible to an operator as they are punched.

    摘要: A flame spray system and a method for applying uniform coatings of powdered plastics to surfaces which utilizes a pressurized carrier gas stream to transport plastic powder to a spray gun. The spray gun passes the powder through a flame produced at the end of the spray gun, melting the powder into droplets. When the molten plastic droplets strike the application surface, they adhere and combine to form a solid coat of plastic upon cooling.
