    摘要： The present invention relates to a process for preparing 4,4′-[1-(trifluoromethyl)alkylidene]bis(2,6-diphenylphenols), in particular for preparing 4,4′-[1-(trifluoromethyl)ethylidene]bis(2,6-diphenylphenol), which comprises the self-condensation of cyclohexanone in the presence of a basic catalyst to form tricyclic condensation products, dehydrogenation of the resulting tricyclic condensation products in the presence of a supported transition metal catalyst in the condensed phase to form 2,6-diphenylphenol and reaction of the 2,6-diphenylphenol with a trifluoromethyl ketone. The invention further provides an improved process for preparing 2,6-diphenylphenol by aldol self-condensation of cyclohexanone.

    摘要： A regulating valve comprising a housing having a cylindrical valve chamber, the valve chamber being provided with at least one inlet and at least two outlets, the inlet and the outlets being at least partially closeable as needed by a common valve body arranged in the valve chamber and rotatable around an axis, the valve body being operable by an actuator, the inlet and/or at least one of the outlets being surrounded by a sealing device on the side of the housing facing the valve body and the sealing device being able to be brought into sealing engagement with the valve body under elastic preload. The valve body is designed having the shape of the segment of a cylinder and is bounded on the peripheral side by two boundary surfaces which each have an edge on the side facing the housing, the edge overtravelling the inlet during its opening being designed as an efflux edge and having an elliptically shaped recess extending in axial direction. Configured in the valve body is a duct-shaped opening which extends between the boundary surfaces and penetrates them.

    摘要： A liquid separator for the separation of liquids from gases is disclosed. The separator has an inlet orifice for receiving a flow of the gas laden with liquid, a first outlet for the liquid and a second outlet for the gas liberated from the liquid, and an adjusting mechanism for varying the available cross-sectional area arranged in the inlet orifice. The inlet orifice has a tubular passage cross-section and is bounded along its entire length by a dimensionally fixed wall. The adjusting mechanism has a pressure control assembly having a pneumatically operable control element which is arranged within the inlet orifice in a manner allowing relative movement therewith.

    摘要： A hydraulic valve play equalization element for the valve drive of an internal combustion engine is disclosed. The equalization element comprises an inner tappet and an outer tappet arranged to move relative to one another in the axial direction. The outside tappet is formed by an essentially cup-shaped housing with a level bottom and the inside tappet and the outside tappet delimit an oil-filled storage space which is sealed towards the outside and which can change in volume. A displacement element to equalize volume changes is enclosed in the storage space. The outside tappet is formed by an essentially tube-shaped mantle of thermoplastic material, which has slide surfaces radially inside and outside. The mantle is closed off with a fluid seal, by a disk structured as an expeller, in the direction of a cam shaft that is used. The inside slide surface encloses the inside tappet, resting against its circumference, and forming a fluid seal.
