39results about How to "Sufficient dimensional stability" patented technology

Methods for preparing a shaped rubber article, comprising admixing at least one thermoplastic material and at least one elastomer material to provide a processable and dimensionally stable rubber composition, shaping the composition, and irradiating the composition to form the shaped rubber article. The dimensional stability of the uncured composition may be provided by partial dynamic vulcanization, high performance reinforcing fillers, fractional curing, or combinations thereof. The elastomer material is present in an amount greater than about 65% by weight based on the total weight of the thermoplastic and elastomer materials present in the admixture.

A plunger piston for an air spring. The air spring being active between a component which is to be cushioned by springs, in particular the vehicle frame, and a sprung component, in particular the axle carrier of a motor vehicle. The plunger piston is configured as a hollow piston which is connected to the sprung component at the lower plunger-piston end and to a pneumatic-spring bellows which can be loaded with compressed air at an upper plunger-piston head. The pneumatic-spring bellows is connected on the other side to the component which is cushioned by springs, and rolls on the outside of the plunger-piston skirt during suspension movements. The lower plunger-piston end has an open configuration and has a reinforcing element which encircles the edge region of the opening.

A rail covering for a sliding seat rail between two passenger seats in a cabin of a vehicle has a first and a second elongate covering element. The first and second covering elements are formed complementary with respect to each other, allowing the first covering element to telescopically engage with a lower side of the second covering element. The first covering element has, at least in regions on a lower side, a first guide which displaceably holds the first covering element on the sliding seat rail along the main direction of extent thereof. The second covering element has an open end arranged on the end side and, at an end arranged oppositely on the end side on a lower side, has a second guide which displaceably holds the second covering element on the sliding seat rail along the main direction of extent thereof.

The invention relates to a travel limiting element in a brake booster device for a motor vehicle brake system, comprising a pair of longitudinal legs which are connected together via at least one transverse leg, wherein the travel limiting element can be brought into contact with a stop of the brake booster device. In favor of a simple design and cost-effective production, the travel limiting element comprises two dimensionally stable reinforcement braces which extend along the longitudinal legs, and the transverse leg is made of a damping material which surrounds the two longitudinal legs at least in sections.

A laminated surface covering including a facing material made of vinyl and a backing material comprising a rubber component. The rubber component comprising at least a matrix of bonded rubber granules. A bonding material disposed between the facing material and the backing material. The facing material configured to melt at a temperature between 165° F. and 210° F. infiltrating the backing material thereby essentially encasing the rubber granules of the matrix and providing fire retardation and smoke suppression qualities.

The present invention provides a constituent member of a bearing, which can prolong the life of a ball-and-roller bearing and can ensure sufficient static load carrying capacity and dimensional stability; a process for production of the constituent member; and a ball-and-roller bearing which has a long life and exhibits sufficient static load carrying capacity and dimensional stability. A workpiece obtained by shaping a steel containing 3.2 to 5.0 mass% of Cr and 0.05 to less than 0.5 mass% of V is subjected to heat treatment such as carbonitriding, whereby a constituent member of a ball-and-roller bearing is produced. In the constituent member thus produced, the contents of C and N in the surface layer extending from the surface of the member to a depth of 10[mu]m fall within the ranges of 1.1-1.6 mass% and 0.1-1.0 mass% respectively; the Vickers hardness at a depth of 50[mu]m from the surface falls within the range of 740 to 900 (62-67 in terms of Rockwell C hardness); the content of gamma-iron at a depth of 10[mu]m from the surface falls with the range of 20-55 vol%; vanadium nitride particles having particle diameters of 0.2-2[mu]m and / or vanadium carbonitride particles having particle diameters of 0.2-2[mu]m are made present in the surface layer extending from the surface to a depth of 10[mu]m; and the area fraction of the particles in the surface layer extending from the surface to a depth of 10[mu]m falls within the range of 1-10%.

The present invention relates to a complex and a method for manufacturing same, the complex comprising: at least one crystalline hybrid nanoporous material powder, in which a metal ion, or a metal ion cluster to which oxygen is bound, and an organic ligand, or the organic ligand and a negative ion ligand are in a coordinate covalent bond; and at least one organic polymer additive, or at least one organic polymer additive and an inorganic additive, wherein the shape of the complex is spherical or pseudo-spherical, the size of the complex is 0.1 to 100 mm, a total volume of pores is 5 or more volume % based on the sum of a total volume of nanoporous material having a size of at most 10 nm and a total volume of pores having a size of at least 0.1 μm, and wherein a non-surface value per weight (m2 / g) of the complex as at least 83% of a non-surface value per weight (m2 / g) of the nanoporous material powder.
