摘要： A method for detecting an oversuds condition that can lead to a suds lock condition in a laundry treating appliance includes determining a baseline fill level prior to introducing wash liquid in the cycle of operation; sampling fill levels of the wash liquid during a wash phase of the cycle of operation while wash liquid is being drained; comparing each sampled fill level to the baseline fill level and determining a difference; continuing to sample fill levels for a predetermined period after the difference equals zero; identifying a minimum fill level for the predetermined period; sampling a final fill level after the predetermined period; calculating a difference between the minimum fill level and the final fill level; and identifying a potential suds lock condition if the difference exceeds a predetermined threshold.

摘要： By compressing and heat curing a non-resilient, non-flexible recurable material formed by subjecting cured polyimide foam to the action of pressurized steam, a wide variety of useful articles may be produced. These include tough, flame-resistant plastic films, sheets, panels, boards, and shapes in general; composites (both reinforced and unreinforced); and laminates and other articles in which separate shapes or parts are bonded together by a new type of tough, flame-resistant adhesive. Additionally, heretofore worthless products such as the kerf cut away from buns of polyimide foam during the foam manufacturing process can be converted and vastly upgraded into any of such an array of new articles of manufacture such as those just mentioned.

摘要： A non-flexible, non-resilient recurable cellular material, prepared by exposing cured polyimide foam to an atmosphere of steam at an elevated pressure, is introduced into a honeycomb or like structure so that the cells are at least partially filled with the recurable cellular material. The cellular material is then cured while contained within such cells to form a composite polyimide foam-containing structure. Laminates may be applied to either or both faces of the polyimide foam-containing cellular structure. These articles possess enhanced strength, yet are lightweight and flame resistant, and thus useful for structural, vibration damping and thermal insulation applications.

摘要： A body of cured polyimide foam is treated with steam to produce a non-flexible, non-resilient cellular structure. A molding member is impressed into this structure to a depth less than the full thickness of the structure. The structure is then cured to polyimide foam with the molding member removed therefrom either before, during or after the curing has been completed. The resultant articles, which may be laminated, are useful as panels to dampen vibration and sound, and to provide thermal insulation. In addition the articles are flame resistant and flexible.
