Abstract: In manufacturing two-sided laminated cardboard (1) in a laminating apparatus (10), by controlling band tensions of a first outer layer (11) and a second outer layer (12), a torque difference between an exerted first torque (Q1) in an upper roller (21) and an exerted second torque (Q2) in a lower roller (22) is controlled towards a pre-determined value (?Q) of said torque difference, while at the same time a torque addition sum of the first torque and the second torque is controlled towards a pre-determined constant value (Q) of said torque addition sum. Thus the invention provides an effective and reliable solution for counteracting concaveness or convexness, in the conveying direction (MD), of the two-sided laminated cardboard (1) to be manufactured.

Abstract: In a first step of the method of achieving TRIP microstructure in steels by deformation heat, steel feedstock is heated to a temperature below the temperature at which austenite begins to form in the steel in question, i.e. below AC1. In a next step, the feedstock is formed into a final product, using applied severe plastic deformation whereby deformation energy causes the temperature of the material to increase to the final temperature between AC1 and AC3, and whereupon the ferrite-pearlite microstructure transforms into austenite. In a third or last process step, the final product is cooled down from the final temperature to the temperature of the bainite nose of the material (B). The cooling is then interrupted and the material is held at the temperature of the bainite nose (B). Consequently, the TRIP microstructure forms. Finally, the product is cooled down to ambient temperature.

Abstract: The invention relates to a method of solubilizing expanded polystyrene (EPS), in which the EPS is brought into contact with at least one initial solvent, enabling the transition of the EPS from an expanded solid state to the gel state. The aforementioned gel is subsequently treated with at least one complementary solvent that is different from the initial solvent, enabling the solubilization thereof such as to produce a true solution. The invention also relates to the product thus obtained and to the use of said product.

Abstract: A set for producing an offset resurfacing condyle cap implant for an artificial hip joint is described. The set has a thin-walled metallic cap (1), to be placed onto the hip joint head that has been milled into shape only in polar area (P) and otherwise has been only decartilaged or freshened, with the walls of the metallic cap being steadily enlarged in the cross-sectional view from of 2 mm to 6 mm in thickness in the area of base edge (2), such that an eccentricity results in its external shape and its interior space (I) has first an essentially cylindrical equatorial area (Z) followed in aforementioned polar area (P) by a truncated cone-shaped, conically narrowing area, with several bore holes (4) in its walls, the axes of which run parallel to main axis (H) of cap (1), and at least one peg (5) for centering and load-bearing insertion into bore holes (4) in cap (1).

Abstract: A ball joint or cap for an artificial hip joint is described that is suitable for carrying out a rotating or pivoting motion in an artificial hip joint socket, with a gap being provided for a natural fluid film (synovial fluid) between itself and the artificial hip joint socket, and with regular depressions without interconnecting channels between them being recessed in areas of its surface. It is proposed that its surface in the polar area is smooth and without depressions, that an area is provided in an intermediate area between the smooth polar area and its equator, in which depressions are recessed with hole widths between 1.0 mm to 3.0 mm, that adjacently in the intermediate area in the direction of its base edge, further depressions are recessed, the hole widths of which become steadily smaller, the closer they lie to the base edge, with hole widths between 0.5 mm and 1.0 mm.

Abstract: Described here is a set for the construction of a resurfacing hip implant. It comprises a thin metal cup for cemented insertion into the natural acetabulum, a thin metal cap for cemented placement upon the natural femoral head, and an inlay which can be placed in the cup of the acetabulum as a sliding partner for the cap for the femoral head. Also described are methods of using and implanting the implant.

Abstract: A set is provided for creating an offset-resurfacing hip-joint implant. The set includes a 1 to 1.5 mm thick metallic acetabulum shell (1) for insertion into the natural acetabulum, from which only cartilage has been removed, a metallic head cap (2) for placement on the natural hip-joint head, from which only cartilage has been removed, and an inlay (3) for insertion into the acetabulum shell (1) as a sliding partner for the head cap (2). The inlay has a material thickness of 2 to 5 mm. The head cap (2) has a wall thickness which increases constantly from a thickness of 2 mm to 6 mm viewed in cross section in the region of the base edge (6) of the head cap, so that an eccentricity is produced in its outer shape.

Abstract: The invention relates to a glove, in particular a pilot's glove, having a lining comprising at least one outer layer made up of several material blanks with a glove outer surface, and the outer layer of the lining has no joining point on at least a volar zone and preferably a distal zone in the finger tip region of one or more glove finger(s). The material blanks comprise at least an inner hand part, a top hand part, several finger side parts and optionally a thumb part, and the inner hand part is joined to the other material blanks along a single continuously extending join line 5 to form the at least one glove finger. The invention further relates to a lining comprising material blanks joined to one another and an intermediate element is stitched into the join formed by a seam.

Abstract: The invention relates to a protective glove (1) for protecting certain regions of a user's hand (2) against foreign bodies impacting with it such as bullets and/or stabbing or cutting devices, with a lining (4) made from a material that is not or not very resistant to stabs, cuts or incisions and is not bullet-proof, for example a textile fabric, a leather, a laminate or similar, comprising several glove fingers (10 to 14), and a glove top face (17) extends on an external surface (3) of the lining (4) in the region of finger top sides (19) and in a top hand region (15), and a bullet-proof and/or cut or stab inhibiting protective padding (20) is built up on or placed on certain regions of the glove top face (17) starting from a padding bottom face (21) and is attached to the lining (4) at joining points (22), and the protective padding (20) prevents penetration by foreign bodies impacting with it to a glove interior lying underneath it.
