Patent number: 12163326Abstract: A system for capturing and destroying hair and waste within a commercial shower drain includes a drain basket placed in the drain and a chemical blend that is poured into the drain basket. The drain basket captures hair and waste that is washed down shower drains. The chemical blend is poured into the drain basket to neutralize the captured hair or waste. The result is a clear drain and clear plumbing, with minimal manual labor. The drain basket does not require removal because the hair and waste are neutralized within the drain basket before a clog can develop. The chemical blend is strong enough to neutralize significant quantities of waste within minutes and is safer for both users and the plumbing systems treated than conventional drain cleaning chemicals.Type: GrantFiled: September 1, 2022Date of Patent: December 10, 2024Assignee: NeverClog, LLCInventors: Geoffrey J.

Patent number: 12017305Abstract: The disclosed apparatus, systems and methods relate to the design principles for forming a welded joint between two sections of tubing or pipe. The material at the end portion of a first section of tubing to is folded inwardly to create a support surface. This support surface improves the ability to weld light gage material with traditional arc welding and it creates conditions to allow brazing to be as strong as traditional arc welding by using A shaped piece of filler material which is located at the intersection between the support surface of the first section of tubing and a side wall section of the second section of tubing. While holding together the first and second sections of tubing with the filler material, heat is applied at the intersection at a temperature and for a duration sufficient to melt the filler material and form the 3t joint.Type: GrantFiled: January 13, 2021Date of Patent: June 25, 2024Assignee: Priefert Mfg.
