摘要： The invention relates to an article having a single- or multi-layered main body having elastic properties, in particular an air spring bellows, a metal-rubber element or a vibration damper.
In order to improve its flame retardant properties, the main body of the article consists of or contains at least one layer D constructed from a rubber mixture which is free from halogen-containing flame retardants and contains at least one carbon black having a BET surface area according to DIN-ISO 9277 between 35 and 140 m2/g and an oil absorption number (OAN) according to ISO 4656 between 70 and 140 ml/100 g and a first aluminum trihydrate (ATH_1) and at least a further aluminum trihydrate (ATH_2), wherein the first aluminum trihydrate (ATH_1) and the further aluminum trihydrate (ATH_2) each have a different particle size.-

摘要： Exemplary inventive practice provides a structure that is attributed with superior resistance to loading. For example, an inventive structure includes two coaxial axisymmetric (e.g., cylindrical) shells and a granulation-filled matrix material occupying the peripheral space between the shells. According to some inventive embodiments, the granulation-filled matrix material has a loading-responsive matrix (e.g., shear-thickening fluid or highly rate-sensitive polymer) and granules dispersed therein. When the inventive structure encounters pressure loading at its exterior shell, the consistency of the loading-responsive matrix becomes thicker or firmer and thereby promotes, among the granules, interactive mechanisms (e.g., friction and/or arching) that reinforce the granulation-filled matrix material. According to some inventive embodiments, the granulation-filled matrix material has a magnetic-field-responsive matrix and magnetizable granules dispersed therein, and is magnetically fortified via application of a magnetic field (e.g., continuously applied where the matrix is magnetorheological fluid, or temporarily applied where the matrix is rheological fluid containing diamagnetic particles).

摘要： A method and system for supporting trailers carrying mechanical equipment, such as hydraulic fracturing oil and gas equipment are provided. One, two or at least three supports extend from the trailer toward ground and are configured to partially support the trailer when in contact with ground, in addition to any axle groups that exist on the trailer. At least one device configured to absorb, damp, or both absorb and damp vibrations from the mechanical equipment during operation is provided. Each device is operatively coupled to, for example integrated with, a corresponding one of the support structures.

摘要： A non-metal spring includes two non-metal elastic units connected to each other and formed between two non-metal terminal rings. Each of the non-metal elastic units includes two intermediate rings intersecting each other, thereby providing two cross portions. The cross portions of each of the non-metal elastic units divide each of the intermediate rings into a first portion and a second portion. The first portions of the intermediate rings of one of the non-metal elastic units are connected to one of the terminal rings. The second portions of the intermediate rings of another one of the non-metal elastic units are connected to a remaining one of the terminal rings. The first portions of the intermediate rings of each of the non-metal elastic units are connected to the second portions of the intermediate rings of an adjacent one of the non-metal elastic units.

摘要： An all plastic compression spring assembly includes a slotted tubular spring element formed from a tensile polymer material and upper and lower loading cones received at opposing upper and lower ends of the slotted tubular spring element. The upper loading cone may be axially compressible towards the lower loading cone within the slotted tubular spring element whereby the slotted tubular spring element radially expands in tension to create an opposing radial contraction force, and in turn, an axial extension spring force. When released, the spring element elastically returns to its normal at rest shape, returning the cones to their normal at rest positions. In some dispenser configurations, the lower loading cone may be stationary or fixed within the dispensing head and the upper loading cone may be downwardly compressible toward the lower loading cone by movement of a nozzle head.
