Abstract: A flangeless fluid end comprising a fluid end body releasably attached to a connect plate. The connect plate is attached to a power source using stay rods. The flow bores of the fluid end are sealed without threading a retainer nut into the walls of each bore. Instead, the flow bores are sealed by bolting a retainer to the fluid end body. Plungers to drive fluid through the fluid end body are installed within removable stuffing box sleeves. These sleeves are maintained within the plunger bores by the bolted retainers. A number of features, including the location of seals within bore walls and carbide inserts within valve structures, aid in reducing or transferring wear.

Abstract: A power end assembly includes a crankshaft section, a crosshead section, and a connector section coupled together by one, two, or more sets of stay rods. The power end may include one or more support plates that are coupled to the crankshaft section and/or crosshead section. The crosshead section includes a plurality of individual crosshead frames. The connector section may include a plurality of individual connector plates or may be a unitary connector plate. The power end is configured to be coupled to a fluid end assembly by coupling the fluid end assembly to the connector plates.

Abstract: A fluid end assembly comprising a housing having multiple conduits formed therein. A tubular sleeve is installed within one of the conduits and is configured to house a plurality of packing seals. A seal is installed within a groove formed in the walls of the housing surrounding the tubular sleeve such that the seal engages an outer surface of the tubular sleeve.

Abstract: A hydrophilic salt in water feedstock will be used to produce hydrogen gas (H2) from electrolyzed hydrophilic salt catalyst in water. The saltwater feedstock would be electrolyzed as shown with concentration of hydrogen gas in the saltwater 2H2O+NACL+energy=2H2+O2+NACL and that hydrogen gas can be collected by an unique inductive coil in an enclosed chamber included in the production, extraction, and collection of hydrogen gas (H2) from the dissociated saltwater solution that will be used in today's fuel cell technologies, as a hydrogen fuel additive to hydrocarbon fuels, combustion engines, as well as, other technologies. The proposed process is to be duplicated and utilized in a unique scientifically engineered electrolyzed hydrophilic saltwater device for extraction and collection of a hydrogen gas (H2) production and use.

Abstract: A gas feedstock input is provided to accurately supply a hydrogen source from an input gas feedstock supply. The gas input feedstock will be used for the selective absorption graphene cartridge filter process for the production of 99.9% purity hydrogen gas. The gas feedstock filtration science has shown increases in the concentration of hydrogen at the graphene filter output and that this certified hydrogen production can be used in today's fuel cell technologies, transportation, power plants, and space propulsion technologies, as well as, other technologies. The proposed invention expects the unique hydrogen gas graphene cartridge filter device to be used with any gas input feedstock that contains hydrogen to deliver the purest hydrogen gas of atomic size 1 to 2 Angstroms.
