  • Publication number: 20240408723
    Abstract: An abrasive suspension jet cutting system, the system includes a cutting head. The cutting head has a feed assembly, nozzle and acceleration cavity therebetween. The feed assembly has a slurry orifice and a shielding fluid orifice. Within the acceleration cavity abrasive slurry and shielding fluid are accelerated together from the slurry orifice to the nozzle while maintaining a shielding fluid barrier substantially unmixed with the abrasive slurry around the abrasive slurry. The cutting head is further configured to have both the slurry and shielding fluid pass substantially unmixed through the nozzle thereby limiting nozzle wear. A wear control system is provided to reduce wear of the nozzle and other system components during start and stop. The system may further include a reclamation system that collects and reclaims used abrasive particles and fluid and returns them back to the cutting head to be reused thereby reducing system operational costs.

  • Patent number: 11642965
    Abstract: A system and a method of powering an external device with a vehicular battery system allow a user to charge electrically-powered devices with the electrical power source of his or her vehicle. The system includes an electrically-driven vehicle which includes a high-voltage battery. The system further includes a power modifier, an auxiliary battery, at least one external device, at least one on/off relay, and a user controller. The power modifier modifies the high-voltage DC drawn from the high-voltage battery to safely charge the auxiliary battery. The auxiliary battery stores electrical power. The external device may be any electrically-powered device. The on/off relay allows a user to turn the system on or off when desired. The user controller is communicably coupled to the on/off relay through a relay wireless communication module. The user controller allows a user to remotely operate the on/off relay and, thus, remotely turn the system on or off.
