Patent number: 11779968Abstract: A vessel cleaning device and method includes an armored chassis with track members operable independently by first and second pneumatic drive systems, and a remotely controllable arm. A plurality of nozzles disposed on the arm are configured to rotate while spraying high pressure liquid in mutually opposed directions when the arm is extended. The device is sized and shaped to pass through a 24-inch opening in the vessel when the arm is collapsed, and the track members and the arm are controllable remotely by an operator external to the vessel. Once the device has passed through the 24-inch opening into the vessel, the arm is movable into the extended position, and the device is movable within the vessel while the nozzles spray liquid along a notional circumference to remove waste materials from an interior surface of the vessel.Type: GrantFiled: July 19, 2021Date of Patent: October 10, 2023Assignee: Clean Harbors Industrial Services, Inc.Inventor: Charles E.

Publication number: 20030030211Abstract: A game system providing multiple levels of integrated play featuring instant progressive awards and variably compounding award amounts. The game system may be one of many types, including seal cards, jar tickets, instant games and lottery tickets. The game system offers the opportunity for awards at an initial level, and a chance for an instant progressive award offered to players qualifying for an upper level. Players eligible for an instant progressive award do not wait until the end of play at the initial level before participating at the upper level. Any upper level progressive award amounts not awarded may be compounded with an award amount associated with the next round of play to create an increased award amount in the next round. Any compounded award amount is variable and not predetermined. The instant progression scheme and variably compounding award amounts increase player interest over multiple rounds of play.Type: ApplicationFiled: August 5, 2002Publication date: February 13, 2003Inventor: Charles E. Brown

Patent number: 6390916Abstract: A seal card game system providing multiple levels of non-progressive play. The game system awards a master case award to a winning ticket not among the population of individual deal winning tickets. A winning ticket of each deal set does not qualify for the master case award level. The game features segregated deal sets, each set containing break-open tickets. Each deal set is segregated by deal identifier indicia. In one exemplary embodiment, the deal identifier indicia is a selected color which is imprinted on each of the playing tickets comprising a deal set. The play tickets may be serialized by deal or by case for security. A seal card may includes the serialization of each ticket associated with the case. The non-progression scheme benefits the game operator in retaining the interest and participation of a higher population of players throughout the multiple deal play.Type: GrantFiled: March 22, 2001Date of Patent: May 21, 2002Inventor: Charles E.
