The invention relates to an assembled quake-proof mobile house which is achieved by assembling steel-wooden-structure framework-type wall plates with roof plates, connectors and a damping base. Plate frameworks including gable plates, front and back enclosure wall plates and roof plates are all welded by square steel tubes. A wooden board is nailed on the outside of a framework steel tube; and the outside of the wooden board is pasted with water-tight thermal-insulation composite bricks or tiles. The damping base, the major part of which is buffer springs, is arranged at the bottom of the vertical post of the steel tube. Ground beams are arranged at the bottom of the wall plates, and a damping sliding groove is arranged between the ground beams and a foundation. The product provided by the invention can be produced in bulk in factories and then can be assembled after being transported on the site; therefore, the product can solve the long-term living problem in short time for people in stricken area; and if removing is essential, the product can be detached and rebuilt. Due to the damping base and damping sliding groove, when earthquake happens, the product can get rid of lateral shearing force and does not fall down. The assembled quake-proof mobile house has excellent earthquake-proof performance and can be suitable for using as temporary and long-term residences in areas in which earthquakes are common; and the assembled quake-proof mobile house also can be used as temporary headhunters, health centers and supplies warehouses and other buildings on rescue sites.

ActiveUS20120304618A1Shear force on be reduceSmooth flow of propellantCosmonautic vehiclesCosmonautic partsEngineeringShear force
In a propulsion system, an electrohydrodynamic (EHD) body force is used to control the flow of a propellant through a micro channel, expansion slot, plenum chamber, or other flow region and thereby increase the specific impulse created by a propulsion system. In an embodiment, a plurality of electrodes are arranged and powered to create a plasma discharge, which can impart an EHD body force to a fluid. Various configurations of electrodes can be used to control the flow of the fluid into, out of, or through the flow region. In an embodiment, the use of EHD body forces can reduce, or substantially eliminate, shear forces on the surface of a plenum chamber, micro channel, or expansion slot of the propulsion system, resulting in a smooth flow of the propellant and increased thrust.

Roofer's kneepads
InactiveUS20090151039A1Reduce and eliminate pressureOvercome deficienciesRoof toolsProtective garmentKnee protectorDihedral angle
The invention is a wedge-shaped support adapted to be fastened to a user's lower leg to provide comfort when the user is kneeling on an inclined roof, used in pairs. Each shin wedge comprises a wedge of lightweight material capable of supporting the user's weight. The acute dihedral angle of each wedge is approximately equal to the pitch angle of the roof on which the wedge kneepads are being used, thereby providing a substantially horizontal upper kneeling surface when the wedge is oriented towards the peak of the roof. The wedge's lower surface typically comprises a durable pad that prevents premature abrasion of the lightweight material and improves grip onto the inclined surface. Each wedge's upper surface typically includes a soft layer that serves as an ergonomic kneeling pad for the user. An attachment harness secures the wedge kneepad to the user's shin and thigh or knee.
