The new tetraene of formula: ##STR1## is useful particularly as an intermediate in the synthesis of, for example, hexahydropseudoionone, pseudoionone and vitamin A. It may be made by dehydrochlorinating 3-chloro-2-methyl-6-methylene-1,3,7-octadiene in the presence of a palladium catalyst and an inorganic base.
A laundry washing or drying machine having an outer drum (11) and an inner drum (12). The inner drum is rotatably disposed in the outer drum (11) and adapted to support laundry items to be treated in the machine. At one gable (16), the inner drum (12) is connected with a pulley (18) adapted to be drivingly connected to a corresponding drive pulley driven by an electric motor. Further, at one or at both gables, the inner drum (16) is provided with a shaft (17) journalled in a seat disposed adjacent to an opening (22) in a corresponding gable (15) of the outer drum (11). The shaft (17) is formed by one of a pressing (90) made in the associated inner drum gable (16), a pressing (71) made in the central part of the pulley (18), or joint pressings (50, 51) made in the inner drum gable (16) and in the pulley (18). The seat is formed by a central cantilevering (21; 53) in the corresponding gable (15) of the outer drum. The cantilevering (21; 53) is directed toward the inner drum (16) and defines the opening.
