  • Patent number: 9844890
    Abstract: High-pressure fluid jet systems are provided which include a pump to selectively provide a source of high-pressure fluid, a cutting head assembly configured to receive the high-pressure fluid and generate a high-pressure fluid jet for processing workpieces or work surfaces, and a fluid distribution system in fluid communication with the pump and the cutting head assembly to route the high-pressure fluid from the pump to the cutting head assembly. The pump, the cutting head assembly and/or the fluid distribution system include at least one fluid distribution component having a unitary body formed from an additive manufacturing or casting process with an internal passage having at least a curvilinear portion to efficiently route matter through the fluid jet system. Example fluid distribution components include fittings, valve bodies, cutting head bodies and nozzles of the high-pressure fluid jet systems.

  • Patent number: 9739352
    Abstract: A coupler assembly is provided for coupling components in a power transmission system, such as a rack and pinion drive system. The coupler assembly includes a floating mount and a pair of clamp members movable between an unfastened configuration in which the floating mount is adjustably supported between the clamp members and a fastened configuration in which the floating mount is fixedly secured between the clamp members. At least a pitch and a yaw of the floating mount are adjustable when the clamp members are in the unfastened configuration. Methods and systems which relate to or include the aforementioned coupler assembly are also provided.
