    Abstract: An actuator includes a housing that defines a first inlet to receive a fluid, a second inlet to receive the fluid and a chamber. The actuator includes an actuator rod movably coupled to the housing. The actuator rod includes a head. A first face of the head is responsive to the fluid from the first inlet, and a second face of the head is responsive to the fluid from the second inlet to move the actuator rod. The head defines at least one cross-bore. The actuator includes at least one plug coupled to the cross-bore to inhibit a flow of the fluid through the cross-bore in a first state such that the plug fluidly isolates the fluid from the first inlet from the fluid from the second inlet. The plug is to enable the flow of the fluid through the at least one plug in a second state.

    Abstract: A flow restrictor includes a first flowbody defining a first end portion, a second end portion opposite the first end portion and an orifice between the first end portion and the second end portion. The first end portion defines a plurality of first slots, and the second end portion defines a counterbore having a first diameter. The flow restrictor includes a second flowbody defining a plurality of second slots and having a second diameter proximate the plurality of second slots that is greater than the first diameter of the first flowbody. The second flowbody is configured to be received within the counterbore of the first flowbody.

    Abstract: A fibrous substrate for depositing carbon generated from pyrolysis of a hydrocarbon may include at least one roll defining a plurality of rolled deposition surfaces configured to receive carbon generated from the pyrolysis. The fibrous substrate may further include at least one spacer between and spacing at least one pair of opposed deposition surfaces of the plurality of rolled deposition surfaces. A system for generating hydrogen gas may include a pyrolysis reactor configured to generate the hydrogen gas from a hydrocarbon through pyrolysis. The system may further include the fibrous substrate. A method for forming the fibrous substrate may include positioning the at least one spacer on a surface of a fibrous mat, and rolling the fibrous mat into the at least one roll.

    Abstract: A piston pump includes a ported member that is moveably disposed within an internal space of a housing between a rotating group and the housing. The ported member includes a first face facing the rotating group and a second face facing a fluid inlet and outlet. The ported member includes an intake port and a discharge port. Moreover, the ported member includes a balance aperture configured to pass fluid between the biasing member and a pump chamber as the rotating group rotates within the internal space such that the biasing member biases the ported member toward a balanced position within the internal space. The balance aperture has a rim at the first face. The rim is clefted at a relief feature of the first face. The relief feature is recessed into the first face.

    Abstract: A piston pump includes a rotor member with a bore therein. The bore is defined by an inner surface. The piston pump also includes a piston supported for reciprocating movement in an axial direction within the bore to change a volume of a pump chamber that is cooperatively defined by the piston and the rotor member. The piston has an outer surface that faces the inner surface with a leakage interface defined therebetween. The leakage interface is configured to receive a passive leakage flow of a fluid from the pump chamber through the leakage interface to provide cooling. Moreover, the outer surface includes a relief feature that is recessed into the outer surface to define, with the inner surface, a cooling pocket of the leakage interface. The cooling pocket moves in the axial direction relative to the inner surface with the reciprocating movement of the piston.
