Abstract: The invention relates to a roller hearth furnace for the heat treatment of coated metal sheets as well as to a corresponding method. The objective of the invention is to put forward a roller hearth furnace that allows the alternating processing of AlSi-coated metal sheets and metal sheets with zinc alloy coatings for hot-working, whereby considerably less effort is involved for the alternating procedure than is the case in the state of the art. The roller hearth furnace according to the invention for the heat treatment of coated metal parts is characterized in that it has at least a first zone and a second zone, whereby in the first zone, a temperature below the melting temperature of the AlSi deposits or a temperature of more than approximately 900° C. [1652° F.] can be maintained, whereas in the second zone, a temperature of more than approximately 870° C. [1598° F.] can be reached.

Abstract: Method of producing a composite pressure vessel (1) having an inner vessel (4) made of thermoplastic material, having at least one end piece (6) provided in a neck region (2), and having a wrapping (5) which reinforces the inner vessel (4) and is made of a fibre material, wherein the method includes production of the inner vessel (4) by extrusion blow moulding and the end piece (6), while the inner vessel is being shaped, is formed on the inner vessel such that the end piece (6) is at least partially enclosed by the inner vessel (4).

Abstract: The invention concerns a fuel tank made of thermoplastic material with at least one sheet-like stiffening element (1) which is connected to the tank wall, consists of material that has a higher modulus of elasticity than the base material of the fuel tank and which is connected to the fuel tank with interlocking engagement on the outer side thereof, the stiffening element (1) not being completely enclosed by the base material of the outer tank wall.

Abstract: A device to drain uncontrolled urine release in male persons has a body (10) made of soft, pliable material whose central cross section forms an approximately circular cylindrical mantel (12) matched to the penis cross section, to which a collecting chamber (13) connects on one end which is funnel-shaped, narrowing in the direction of a hose connection (14). On the other open end, the mantel (12) is subdivided into multiple tongues (16a, 16b, 16c) through interruptions (18a, 18b, 18c) which follow each other in a circumferential direction, and on the body (10) at the transition from the closed mantel (12) to the tongues (16a, 16b, 16c), a soft elastic pliable sleeve (35) is applied or can be applied, which is suitable for enclosing the tongues elastically from outside.
