Abstract: A decorative cover is adapted for receiving and storing a plumbing plunger in a generally upright position. The decorative container includes a base member for receiving the plumbing plunger and a cover member for engaging the base member and covering the plumbing plunger. The base member has a generally flat bottom wall and four generally inwardly tapered intersecting sidewalls extending upwardly from an upper surface of the bottom wall by a predetermined distance. A portion of the bottom wall extends outwardly beyond the sidewalls to establish a supporting lip. The cover member has four intersecting sidewalls which taper inwardly from a lower end to a curved upper portion. The cover member is sized and shaped to surround and snugly engage the sidewalls of the base member when the cover member is installed on the base member. The lower end of the cover member engages and is supported by the base member supporting lip.

Abstract: An integrated system for coating an inner wall surface of a tube is disclosed. A hose has an applicator nozzle attached at a forward end thereof. A payout guide is drivingly engaged with the hose to drive and to remove the hose and the applicator nozzle into and through and from the tube, respectively. A fluid supply system is in fluid communication with the hose, and includes a fluid source supplying a fluid to the hose and applicator nozzle, and a supply valve interposed between the fluid source and the applicator nozzle for selectively applying the supplied fluid to the applicator nozzle. A control system is connected to the payout guide to control the driving and removing of the hose and to the supply valve to control application of the supplied fluid to the applicator nozzle.

Abstract: An ozone generating apparatus includes an ozone generator having concentric electrodes and a means for generating a corona discharge between the electrodes, a pump for recirculating a portion of the ozone-containing gas leaving the generator through a conduit which is configured to receive a portion of the ozone containing gas, and a heat exchanger for cooling the recirculated portion of the ozone-containing gas. An oxygen-containing gas is also introduced to the heat exchanger and combined with the recirculated gas portion to form a feed gas which is chilled in the heat exchanger and then introduced into the generator.
