    Abstract: An energy diffusion sealing ring [872] for use with a hydrocyclone or pump is provided. The energy diffusion sealing ring [872] comprises a sacrificial suspension matrix [872A] comprised of a polymer, elastomer, or combination thereof, and a number of packed inserts [872B] suspended in the matrix [872]. The matrix [872] serves as delivery means for the inserts [872B] into one or more recessed portions [833, 841]. The inserts [872B] comprise a hard material (e.g., ceramic or carbide) and form wear bodies which slow and dissipate kinetic energy of escaping slurry by way of creating paths of resistance. As the suspension matrix [872A] erodes over time, a plurality of interstices [872C] between the inserts [872B] are formed. Escaping slurry [852] slows as it traverses three-dimensional serpentine paths defined by said interstices [872C], thereby reducing its potential to wear surrounding components. Methods for manufacturing an energy diffusion sealing ring [872] and for dissipating the energy of slurry [850] are also disclosed.

    Abstract translation: 提供了用于水力旋流器或泵的能量扩散密封环[872]。 能量扩散密封环[872]包括由聚合物，弹性体或其组合组成的牺牲性悬浮基质[872A]以及悬挂在基质[872]中的多个填充插入物[872B]。 矩阵[872]用作插入物[872B]进入一个或多个凹入部分[833,841]的输送装置。 插入物[872B]包含硬质材料（例如陶瓷或碳化物）并且形成磨损体，其通过产生阻力路径来减缓并消散逃逸浆料的动能。 随着悬浮基质[872A]随时间侵蚀，形成插入物[872B]之间的多个空隙[872C]。 溢出的浆料[852]在穿过由所述间隙[872C]限定的三维蛇形路径时减慢，由此减少其磨损周围组件的可能性。 还公开了用于制造能量扩散密封环[872]和用于耗散浆料[850]的能量的方法。

    Abstract: The invention relates to a sealing arrangement for metal components, wherein the sealing arrangement has an electrical insulating effect, and wherein the sealing arrangement comprises a ceramic layer and a base soldering material disposed thereon, to which germanium is added. The addition of germanium advantageously ranges from 0.1 to 5.0 mole %, preferably between 0.5 and 2.5 mole %. A particular embodiment of the invention provides for the use of a solder which additionally comprises silicon in the range from > 0 to 2.5 mole %, preferably between 0.1 and 0.9 mole %. Furthermore, solder having a further addition of 10 to 40% by volume of Al
    2 TiO
    5 , preferably between 20 and 30% by volume of Al
    2 TiO
    5 , has proven to be particularly suited for said sealing arrangement. The use of the particular solder composition inside the sealing arrangement generally results in reproducibly tight and insulating joints having the following properties: a) the exiting of solder is prevented and the running of solder is reduced, b) the porosity in the solder (primarily individual pores or narrow pore lines) is clearly reduced, c) the soldered connections have sufficient electrical resistance, and d) the soldered connections are generally sufficiently gas-tight (leakage rate during He leak test -3 mbar*1*s
    -1 ).

    Abstract: A gasket material comprising polytetrafluoroethylene (PTFE) and a thermoplastic polymer having a melting point lower than the melting point of PTFE. Preferred thermoplastic polymers comprise fluorinated thermoplastic polymers, and most preferred fluorinated thermoplastic polymers comprise fluorinated ethylene propylene and perfluoroalkoxy copolymer. The PTFE component preferably comprises full density PTFE, and a filler material may optionally be added. The PTFE component is present in the gasket material in an amount from approximately 50% to less than 100%, based on the total weight of the gasket material, and the thermoplastic polymer is present in an amount from greater than 0% to approximately 20%, based on the total weight of the gasket material.
