  • Publication number: 20190145392
    Abstract: A cryogenic pump includes a drive assembly and a pressurization assembly operatively coupled to each other. The drive assembly includes a housing having sidewall and piston slidably disposed therein, the sidewall and a first surface of piston defining expansion chamber. A fuel supply valve is provided in fluid communication with supply of liquid cryogenic fuel and configured to selectively provide liquid cryogenic fuel into expansion chamber. A heating element extends at least partially into expansion chamber to heat and facilitate vaporization of liquid cryogenic fuel, thereby increasing pressure within expansion chamber and causing movement of piston in first direction. The pressurization assembly includes barrel defining bore and a plunger slidably disposed therein to define pressurization chamber for receiving liquid cryogenic fuel. The plunger is driven by the piston such that the movement of piston in first direction causes movement of plunger to pressurize cryogenic fuel within pressurization chamber.

    Abstract: A method for controlling an engagement of a lock-up clutch (LUC) of a torque converter of a machine is disclosed. The method includes detecting a pedal tap of a pedal, wherein the pedal tap is detected when the pedal is depressed from a position corresponding to a pedal displacement less than a first threshold displacement to a position corresponding to a pedal displacement greater than a second threshold displacement, and then released to a position corresponding to a pedal displacement less than the first threshold displacement within a threshold time duration. The method further includes causing the LUC to move to the LUC unlocked position if the pedal tap is detected.

  • Patent number: 10287129
    Abstract: A spool holder includes a cylinder defining a longitudinal axis and having an external surface on which a spool of wire may be supported. A first plate is positioned at a first end of the cylinder and a second plate is positioned at a second end of the cylinder. Both first and second plates have portions extending radially outward from the external surface of the cylinder. The first and second plates both have a perpendicular orientation relative to the longitudinal axis. The first and second plates restrict axial movement of the spool of wire therebetween. The first plate and cylinder are stationary relative to a mounting structure, while the second plate is configured to rotate with the spool of wire. A mechanism urges the second plate and, thus, the spool of wire toward the first plate, thereby regulating rotation of the spool of wire.
