A shielding device for shot blasting or shot peening chambers comprising a shot retention chamber, preferably with multiple interior compartments formed by divider walls, which retains a protective layer of shot to absorb the high energy impact of high velocity shot particles, the shot layer being retained by magnetic or electrically enhanced magnetic means such that the shot retention chamber can be mounted at any angle up to 90 degrees above or below horizontal.

Systems and methods herein convey a coin that is verified and sorted as to one of a plurality of denominations, by a coin verifier, that sorts the coin to a corresponding one of a plurality of rotating conveyor belts equal in number to the number of denominations. The corresponding one of the plurality of rotating conveyor belts rapidly conveys the sorted coin of one denomination at a constant speed to a drop point disposed above a corresponding one of a plurality of coin storage devices, whereupon the sorted coin of one denomination is dropped into the corresponding one of the plurality of coin storage devices.

Rapid conveyance of coins by rotating conveyor belts

A ball peening machine used for forming or surface treatment is constructed with a unique delivery system. The peening media is loaded by gravity from a hopper to a conveyor belt which is constructed with paddles extending transverse to the direction of travel. The media is delivered to the work piece at the end of the conveyor where it turns sharply downward. The paddles tend to propel the media downward.
