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.

Abstract: An animal control apparatus includes a belt to be removably secured about the midsection of a user and a strap attached to the belt at first and second attachment locations on an outside surface of the belt such that a portion of the strap extends along a portion of the outside surface of the belt between the first and second attachment locations. Spacing the first attachment location from the second attachment location creates a loop between the portion of the belt and the portion of the strap. The loop may receive a linking device attached to a lead of an animal such that the user of the apparatus may control the animal in a hands-free manner while allowing the animal a degree of freedom as a result of the linking device sliding along the strap between the first and second attachment locations of the loop.
