The magnetic coupling allows the cage to hang at an angle from the lower sprinkler body plate when fluid is not sprayed onto the cage and/or to provide for a speed dampener of the rate of nutation of the cage.

Various embodiments of a hammermill system, hammer, and methods are disclosed. A hammermill hammer comprises a metal composite comprising a plurality of inserts and a body portion disposed between each of the plurality of inserts. The composition of the plurality of inserts is different than composition of the body portion. The material of the plurality of inserts has a greater abrasion resistance than the material of the body portion and the material of the body portion has a greater impact resistance than the material of the inserts. The hammers produced have improved wear resistance and longer useful life compared to conventional hammermill hammers.

The present invention relates to a micro chamber plate, and more particularly, to a micro chamber plate having micro chamber holes formed using a flowable film. Thus, samples can be injected into the micro chamber holes in a smoother manner compared to when samples are injected using a vacuum and/or centrifugal force. In addition, bubbles and excess samples in the micro chamber holes can be efficiently discharged, making it possible to perform reaction and analysis in a more accurate and efficient manner.
