A sole for a shoe, in particular a sports shoe, includes a unidirectional bending element. The unidirectional bending element enables a dorsal bending of the sole (bending of the sole in the direction upward and away from the ground) and blocks a plantar bending of the sole (bending of the sole in the direction downward and towards the ground). The unidirectional bending element may be arranged at a first layer of the sole and may vertically project from the first layer.

A guide vane ring of a turbomachine, in particular of an axial-throughflow turbine, includes a vane group (6) having a plurality of vanes (2). The vane group (6) has a vane root (11) which has two flanges (12, 13). The vane group (6) is fastened to a vane carrier by means of the flanges (12, 13). In order to reduce stresses in the vanes (2) which occur during deformations of the vane carrier, one flange (13) has on a front end portion (14) and on a rear end portion (15), radially on the inside and radially on the outside, in each case a contact zone (18) which bears against the vane carrier. The other flange (12) has on one end portion (15), radially on the inside, a contact zone (18) which bears against the vane carrier, and is spaced apart from the vane carrier radially on the outside. Moreover, this flange (12) has on the other end portion (14), radially on the outside, a contact zone (18) which bears against the vane carrier, and is spaced apart from the vane carrier radially on the inside. Furthermore, the flanges (12, 13), between their end portions (14, 15), are spaced apart from the vane carrier radially on the inside and radially on the outside.

The invention relates to a separated safety run-flat spring tyre, and belongs to a rubber light industrial product. The separated safety run-flat spring tyre comprises a tyre casing outer side and a tyre rim matched with the tyre casing outer side, wherein a compression spring matched with the tyre casing outer side is arranged on the inner surface of the tyre casing outer side; a tyre casing stabilizing layer is arranged between the compression spring and the tyre casing outer side; and a tyre crown of the tyre casing outer side is closely fitted with the tyre rim through a tyre rim backing layer. The pneumatic tyre with the air supporting tyre casing is replaced by the spring tyre, so that the technical problems that the conventional tyre is easily punctured and also has the phenomena of air leakage and tyre burst are solved, and the separated safety run-flat spring tyre is not required to be inflated with air and patched and suitable for the filed of motor vehicles such as automobiles, motorcycles, bicycles, armored cars and airplanes, or non-motor vehicles.

The present invention provides a moisture-curing sealant comprising a) at least one silane-functional polymer and b) at least one catalyst for the crosslinking of the silane-functional polymer, said sealant being free of organotin compounds and having, in the cured state, a secant modulus at 100% elongation and 23° C., determined to ISO 8339, of less than 0.4 MPa and a resilience at 100% elongation, determined to ISO 7389, of greater than 70%. The sealant is especially suitable as a construction sealant of the 25LM class according to DIN EN ISO 11600, especially as a facade sealant, or as a sealant according to ASTM C719 Class 50.

An object of the invention is to provide a golf ball excellent in the durability at the normal and low temperatures, flight distance, and shot feeling on the shots. Another object of the present invention is to provide a golf ball excellent in a direction stability on the shots. The present invention provides a golf ball comprising: a core consisting of at least one layer; and a cover covering the core and having a thickness ranging from 0.3 mm to 1.0 mm, wherein the cover is formed from a cover composition that contains as a resin component, (A) a highly elastic polyamide resin (B) a metal-neutralized product of binary copolymer and / or ternary copolymer, and (C) a resin having a polar functional group in a specific amount, and wherein the cover composition has a slab hardness ranging from 65 to 75 in Shore D hardness.

An object of the invention is to provide a golf ball excellent in the durability at the normal and low temperatures, flight distance, direction stability and shot feeling on the shots. The present invention provides a golf ball comprising: a core consisting of a center having a diameter of 35 mm or less and a surrounding layer covering the center; at least one intermediate layer covering the core, said intermediate layer having a thickness ranging from 0.5 mm to 1.2 mm and a density of 1.10 g / cm3 or more; and a cover covering the intermediate layer and having a thickness ranging from 0.3 mm to 1.0 mm, wherein the cover is formed of a cover composition that has a slab hardness ranging from 65 to 75 in Shore D hardness and contains as a resin component; (A) a polyamide resin composition having a flexural modulus in a range from 700 MPa to 4,000 MPa and a melt flow rate (240° C., 2.16 kg) of 5.0 g / 10 min or more; (B) at least one member selected from the group consisting of an ethylene-(meth)acrylic acid binary copolymer, a metal-neutralized product of the binary copolymer, an ethylene-(meth)acrylic acid-(meth)acrylic acid ester ternary copolymer, and a metal-neutralized product of the ternary copolymer; and (C) a fluidity improving agent.
