Rubber composition, aging-resistant rubber product using the same
The present invention discloses a rubber composition, a processing method thereof, and an aging resistant rubber product using the rubber composition. The rubber composition comprises a rubber matrix and essential components, wherein, based on 100 parts by weight of the rubber matrix, the rubber matrix comprises a branched polyethylene with a content represented as A, in which 0<A≤100 parts, and an EPM and an EPDM with a content represented as B, in which 0≤B<100 parts; and the essential components comprise 1.5-10 parts of a crosslinking agent, 30-200 parts of a reinforcing filler, and 5-250 parts of a plasticizer. The rubber composition provided by present invention has good processability and can be used for producing rubber products with high aging resistance and compression set resistance.
HIGH-PRESSURE BEARABLE SCALE TYPE BRIDGE RUBBER BEARING
The present invention provides a high-pressure bearable scale type bridge rubber bearing, comprising spring rubber vibration reduction pad assemblies, a flexible steel plate assembly and a rubber bearing body. The rubber bearing body comprises an outer rubber portion and an inner rubber portion; the outer rubber portion is wrapped around the outside of the spring rubber vibration reduction pad assemblies and the flexible steel plate assembly; the spring rubber vibration reduction pad assemblies are arranged on the upper side and the lower side of the inner rubber portion; and the flexible steel plate assembly is fixedly mounted between the spring rubber vibration reduction pad assemblies. The rubber bearing of the present invention has a relatively large elastic deformation after being loaded and can effectively conduct vibration reduction and earthquake resistance during use.
STOWABLE DOCK SYSTEM
At least one of a method, apparatus, and system, as discussed herein and depicted in the figures that includes a first dock section, the first dock section including a first proximal end and a first distal end; a second dock section, the second dock section including a second proximal end and a second distal end; and a moveable guide system that connects the first dock section and the second dock section in a deployed position, such that the first proximal end of the first dock section abuts the second distal end of the second dock section, wherein the moveable guide system is configured to allow for the first dock section to be guided into a stowed position, on top of the second dock section.
Elongate pipe-based support structure
The present invention is a support structure including elongate hollow cylinder and flat plates secured thereto. A first rigid flat plate is horizontally disposed in overlying relation to each hollow cylinder and a second rigid flat plate is horizontally disposed in underlying relation to each hollow cylinder. Stress-distributing strengthening members are circumferentially positioned about the hollow cylinder and secured to their associated rigid flat plates. A key may extend from a first end of each hollow cylinder and a mating socket may be formed in a second end of each hollow cylinder to facilitate end-to-end interconnection of a plurality of hollow cylinders.
Vehicle Body and Method for Assembling a Vehicle Body
A vehicle body includes a primary vehicle structure and interior vehicle fittings as well as a coupling device for fastening the interior vehicle fittings to the primary vehicle structure. The coupling device is configured to generate a magnetic field, so as to fasten the interior vehicle fittings to the primary vehicle structure without contact. Methods for assembling a vehicle body as well as an edifice are also described.

Heavy load bearings and related methods
Bearing assemblies, bearing components and related methods are provided for heavy load applications. In one embodiment, a bearing assembly includes a first bearing apparatus having a base member and a first plurality of polycrystalline diamond compacts (PDCs) on a first surface of the base member, the first plurality of PDCs defining a first collective bearing surface. A second bearing apparatus is configured to engage and slide over the first collective bearing surface. the second bearing apparatus may include a second plurality of PDCs defining a second collective bearing surface. The collective bearing surfaces may be configured to be substantially planar or substantially arcuate. Such bearing assemblies may be implemented in, for example, bridges, roadways, buildings, railways and other structures and machines that may require heavy load bearing support.

VIBRATION DAMPING DEVICE FOR STRUCTURE
A vibration damping device for a structure 1 includes a circular tubular member 3 having a circular tubular inner peripheral surface 2; a columnar elongated member 6 which is disposed in the circular tubular member 3 relatively movably in a direction X with respect to the circular tubular member 3 and having a circular tubular outer peripheral surface 5; and a circular tubular elastic member 10 which has a circular tubular member outer peripheral surface 8 fixed to the inner peripheral surface 2 of the circular tubular member 3 and a circular tubular member inner peripheral surface 9 fixed to the circular tubular outer peripheral surface 5 of the elongated member 6, and which is disposed between the inner peripheral surface 2 of the circular tubular member 3 and the outer peripheral surface 5 of the elongated member 6.
Self-centering viscous damper with pre-pressed ring springs
Disclosed is a self-centering viscous damper with pre-pressed ring springs. The self-centering viscous damper with pre-pressed ring springs comprises a first inner cylinder, a second inner cylinder, a third inner cylinder, an outer cylinder, a first end cover, a second end cover, a piston, a piston rod, a ring spring, a first connector, a second connector, a first linking nut, a second linking nut, a first outer cover, a second outer cover, a first end and a second end. Due to the interaction between the inner and outer cylinders, the ring springs are further pressed whether a damper is tensioned or pressed. The ring springs have been applied with pre-pressure which overcomes a frictional force and a restoring force when the ring springs are in an initial equilibrium position.
