Abstract: A plumbing apparatus for connecting a tail piece to a waste pipe is provided. The apparatus comprises a body having a top flanged end including an inlet configured for receiving the tail piece, a bottom end having an outlet for receiving the waste pipe, and a channel extending between the inlet and outlet. A seal extends about the channel for forming a watertight seal between the tail piece and the waste pipe. A plate is secured to the top flanged end for securing the apparatus to the floor above the waste pipe, may be removable to facilitate post-installation maintenance, and may have an off-center opening to fit various waste pipe configurations. The apparatus is useful for installing plumbing fixtures such as bathtubs, particularly where there is no access from underneath such as in already built homes.

Abstract: The system includes a first heat exchanger in which the refrigerant is injected directly into the content of the first liquid circuit through at least one nozzle to simultaneously capture latent heat from the content as purified frozen liquid pieces are formed. It also includes a second heat exchanger in which the refrigerant transfers the latent heat captured from the content of the first liquid circuit to a content of the second liquid circuit, thereby raising the content of the second liquid circuit in temperature. The proposed concept provides designers with opportunities to create highly efficient systems and methods where the latent heat extracted for the purification is immediately employed to a useful purpose.
