Two motors are arranged on opposing sides of a common shaft, drive plates of the pump / motors being rigidly coupled to each other, for example by being in hard contact with opposing sides of the shaft. By providing hard contact between the pump / motor drive plates and a common shaft, the drive plates and shaft act as a substantially solid element under compression, thereby substantially canceling axial loads generated by the pump / motors directly through the shaft. Residual axial loads are handled via bearings positioned on the shaft adjacent the drive plates in such a manner that the drive plates are in light contact only with the bearings. As a result, friction experienced by the bearings is substantially reduced as compared to conventional systems, thereby improving the efficiency of the system. To further reduce loads on the bearings, the pump / motors are arranged to ensure that they generate radial forces in a direction that is opposite to that of a separation force generated by a torque transferring device carried on the shaft and transmitted to the bearings. A common housing surrounding the two pump / motors, bearings and torque transferring device is divided into three regions, to segregate the bearings and torque transferring assembly from the pump / motors. In this manner, the regions containing the pump / motors are substantially filled with oil to, for example, fully lubricate the pump / motors, while the central region containing the gears and torque transferring device contains a significantly smaller volume of oil to simply splash lubricate the contents of the region, thereby reducing drag on the bearings. Control means are provided for selectively moving the two pump / motors substantially simultaneously to a selected displacement angle, using mechanical systems alone and in combination with hydraulic systems.

A gasket for preventing separation of interconnected pipes without damaging the pipes. The gasket includes a compressible body having a plurality of metal segments partially embedded therein. Each of the metal segments includes a row of exposed teeth configured for engaging a spigot end of a pipe and a trough configured for pivotably engaging a bead on a bell. The trough is further configured for shearing or deforming the bead and inhibiting over-pivoting of the segment about the bead when the pipes are partially withdrawn away from one another, for example, during over-pressurization of the pipes.

A lift-driven wind turbine has a turbine rotor with blades mounted to the turbine shaft by two struts hinged to the shaft and each blade to form a four-bar linkage. The blades' airfoil cross section generates lift that rotates the blades around the axis in the presence of a prevailing wind. The airfoil chord forms a geometric angle of attack αG relative to the tangent of the blade path and the struts orient the blades with an outward tilt angle γ. The turbine is designed with values of αG and γ that cause the lift generated by each blade to have an upward component that supports the blade against the force of gravity and a mean radially inward component that substantially balances centrifugal forces on the blade. Wind turbines designed according to the principles disclosed herein facilitate the construction of free-floating utility scale wind turbines for deep water installations.

The invention relates to couplings for fluid flowlines and more particularly to couplings that can be dismantled comprising flanges and a static ball-and-socket joint for use with flowlines having a diameter lying in the range 40 mm to 200 mm and transporting fluids (gases or liquids) of high penetrability, at high temperature of up to 800° C., and at high pressure of up to 450×105 Pa. Teh device comprises a flanged coupling device with a static ball-and socket joint comprising a first coupling member (1) having a conical sealing surface (8), a second coupling member (3) having concave sealing surface (10) of spherical shape, a two-barrier metal gasket (2) disposed between the sealing surface (8, 10) of the first and second coupling members (1, 3), and assembly means (4) for assembling the first and second coupling members (1, 3) together so as to hold the gasket (2) between their respective sealing surfaces (8, 10). The metal gasket (2) is made of a refractory granular nickel alloy that withstands hydrogen, having uniform fine grain structure with isotropic properties and coated in three sealing layers, the first layer (27) being of nickel, the second layers (28) being of silver, and the third layer (29) being an antifriction lubricant of an inorganic material that is compatible with the fluid used.

The invention discloses a wooden horse toy. The wooden horse toy comprises a wooden horse body, a base seat and a supporting rod used for supporting the wooden horse body on the base seat in a balanced mode, wherein an elastic element is connected between the wooden horse body and the supporting rod. The wooden horse toy further comprises a rotation shaft which at least partially extends into the wooden horse body and rotates through the driving of a power device, wherein the rotation shaft is fixed on the fixing rod through a radial bearing. A first contact part is arranged in the wooden horse body, a second contact part used for driving the first contact part to swing intermittently is arranged on the rotation shaft, the rotation shaft drives the second contact part to rotate, and shifts the first contact part to swing towards one side when the second contact part contacts the first contact part, so that the wooden horse is driven to swing towards one side, when the second contact part rotates to leave the first contact part, the elastic element force the wooden horse body to return, the cycle repeats, and the swinging of the wooden horse body is achieved.

The invention discloses a toy which comprises a toy body, a base and a supporting rod. The toy body is supported on the base through the supporting rod in a balanced mode, an elastic element is connected between the toy body and the supporting rod, a rotary shaft driven by a power device to rotate is arranged in the toy body, and fixed to the supporting rod through a radial bearing, a first contact piece is arranged in the toy body, and a second contact piece for pushing the first contact piece to swing intermittently is arranged on the rotary shaft. The rotary shaft rotates to drive the second contact piece to rotate, and when the second contact piece is in contact with the first contact piece, the first contact piece is shifted to swing towards one side, and therefore the toy body is driven to swing towards one side. When the second contact piece rotates away from the first contact piece, the elastic element forces the toy body to reset, and the process is circulated in the same way, so that the toy body swings.
