Abstract: The invention relates to a method for production of an auto-adhesively bonded, porous, pressure-resistant molding made from comminuted lignocellulosic fibrous materials that are processed at temperatures between 120° C. and 180° C. and a pressure between 2 bar and 8 bar to yield a fiber suspension that is subsequently filled into a mold or applied to a carrier and dried without the addition of a synthetic binder.

Abstract: The invention relates to a revolving gear consisting of a housing (G), a shaft (W), an intermediate member (Z) and an output member (A). The shaft is revolvably guided in the housing in a rotating joint (wb) and actuates the intermediate member by means of a curved joint (zw). The intermediate member is supported by a curved joint (zg) in the housing and is actively connected to the output member by another curved joint (za). The curved joint between the intermediate member and the housing has a controlling section enabling movement to be transmitted to the output member and a locking section preventing movement from being transmitted to the output member. The output member is unequivocally guided in the housing and transmits movement to at least one valve (V).
