International Classification:

A47B 8504

US Classification:

Abstract:

An improved, space-saving bench/table combination assembly which is convenient, compactable and storable, as well as being exceptionally stable and steady in fully expanded disposition, comprises a bench section or portion having pivotally attached thereto a seat back component or portion adapted to be placed at least substantially upright with respect to the seat section which component folds upwardly and outwardly forward ahead of the bench section to present and position its front section in a substantially horizontal plane as a table top from which top depends at its leading or outermost extended edge fold-out legs that are retractable to storage on the back side of the seat back component providing positive and solid table support nicely effective beyond the center of gravity between the leading edge of the table and the bench section of the completely unfolded assembly when it is in such position. The seat assembly advantageously has collapsible, fold-under seat legs which render it very highly compact in completely folded-down condition; it also being excellently stackable for efficient storage in either seat-back bench form or in a completely folded down condition.

Abstract:

A system for separating contaminants from the plastic flake obtained by granulating synthetic plastic containers and products, which have contaminants bonded thereto, has a cryogenic housing for receiving the flake and a transport mechanism incorporated with the housing for moving the flake in a flow stream through the housing. The flake is mixed with a cryogenic medium at a subzero temperature and an impeller receives the frozen flake in a flow stream. An impact wall is provided outboard of the impeller and the impeller is rapidly revolved to radially separate the flakes and hurl the flakes individually at the impact wall with sufficient force to break the bond between the flakes and contaminant.
