The invention relates to stents made of a material with an elongation at rupture of 30% or less and with a tubular base body which entirely or in parts comprises structural segments which are interconnected in longitudinal direction of the stents by means of transverse connectors and in which the structural segments comprise a zigzagging or undulating structure of a brace which is wrapped around the longitudinal axis of the stent. Due to the mechanical properties of the materials used, adaptation of the stent design is required. This is achieved in that in a turning region of the zigzagging or undulating structure the brace comprises a straight bending section aligned in circumferential direction.

A unitized composite aircraft wing includes upper and lower composite laminate wing skins that have differing stiffnesses and are bonded to a composite grid structure. The grid structure includes grid spars extending in a span-wise direction, and cross beams extending in a chord-wise direction of the wing. The grid spars include caps bonded to the upper and lower wing skins.

A torsion bar spring arrangement for a wheel suspension of a motor vehicle includes an actuator arranged on a vehicle body or on a subframe and constructed to variably pre-tension the torsion bar spring arrangement, a coaxial first torsion bar spring having an output side that is connected by way of an output lever to a wheel suspension element of the wheel suspension, and a housing of the actuator supported on the vehicle body in at least one bearing location for movement in a circumferential direction and resiliently yieldingly supported on the vehicle body in the direction of torsional moments acting on the torsion bar spring by way of at least one spring element.

The invention discloses an offshore wind power generation foundation capable of realizing self balance and a wind turbine generator system. The offshore wind power generation foundation comprises a floating platform, a photoelectric conversion device, a water supply hose and a self-balance mechanism; the self-balance mechanism comprises at least three self-balance modules; the self-balance modulescomprise floating bodies, water flow driving pieces, and balance arms provided with water jet channels; water inlets of the water jet channels communicate with the other end of the water supply hose;the balance arms comprise connecting ends and floating ends; the connecting ends are connected with connecting lugs; the floating bodies are arranged on the floating ends; and the water flow drivingpieces communicate into the water jet channels, and are electrically connected with a control device. The balance arms can obtain reactive force, generated by scouring force, to form lateral support on a fan foundation, so that the fan foundation realizes automatic gesture correction, the self-adaption adjustment of the balance state of a wind driven generator can be realized under the precondition of avoiding use of cables, and the overturning of the wind driven generator due to impact and influence from various limit loads such as oceans, currents, wind, waves and the like is prevented.

In a preferred embodiment, an ultra-light weight suspension fork for bicycles that provides smooth action of the suspension system that hitherto has been unachievable. This fork assembly contains a telescoping mechanism located in the head tube of the bicycle that uses linear roller bearings to reduce stiction and prevent torsional losses, but limits weight by only using two such bearings. Side-to-side load is eliminated by the use of two longitudinal members in close proximity to the inner tube of this telescoping mechanism. The telescoping mechanism is coupled to the wheel via an arched single-sided fork crown designed to maintain torsional and braking stiffness. The arched crown contains arches in two dimensions. The fork crown is coupled to the wheel via a shaped fork tube whose wall is thickened while the outside diameter is reduced so that the connection point to the axle mechanism has the same outside diameter as the fork tube thereby enabling significant strengthening of the assembly.

Disengageable ski binding having a carrying plate which is provided as a standing surface for a ski boot and is arranged on a ski-mounted base part such that it can be rotated about a vertical axis of the base part counter to an adjustable resistance of a first latching device, and having disengageable front and rear sole holders which are arranged on the carrying plate, it being the case that the rear sole holders can be disengaged counter to an adjustable resistance of a second latching arrangement, which is separate from the first latching device, and/or the front sole holders are locked within a predetermined angle-of-rotation region of the carrying plate, without affecting the resistance of the first latching device, and are unlocked outside the region of rotation.

A sabot petal having an axis parallel to or coinciding with the launch axis. The sabot petal is formed from a plurality of stacked sheets of composite material consisting of a fiber reinforcement and a polymer resin matrix. Each composite sheet is in a plane rotationally offset from the meridional plane which is defined by the launch axis and radial axis of the sabot petal's cylindrical coordinate system.

A method of braked pivot turning an aircraft, the aircraft comprising a fuselage and a landing gear assembly located to one side thereof. The landing gear comprises a bogie with wheels mounted thereon, at least one wheel being located on a first side of the bogie and at least one wheel being located on a second side of the bogie. The method includes the steps of applying thrust (7″) for moving or turning the aircraft, and via the braking of at least one wheel, applying a greater braking force to the first side of the bogie than to the second side. The first side is located closer to the centre of turning of the aircraft than the second side. The method thereby generates relatively low torque loads in the landing gear leg, reducing fatigue damage. A brake control system is also provided for selectively braking wheels during a turn.

The invention relates to a spinning machine (1) which comprises a plurality of workstations (2), arranged in a row, that have respective spinning devices (5) for producing a thread (9) and a thread traversing device (10) for producing a cross-wound cone (8) that is rotatably received in a cone reel (22) of a cone winding device (6), a device (19) for supplying the negative pressure required for spinning and a drive (14) for the common traverse of the thread guides (11) of the thread traversing devices (10). The invention is characterized in that at least the drive (14) for the thread traversing devices (10) and the device (19) for supplying the negative pressure required for spinning are arranged in the only machine frame (3) of the spinning machine (1), the machine frame (3) being interposed between the workstations (2) of the spinning machine (1) in such a manner that the number of workstations (2) on every side of the machine frame (3) is at least 40% of the total of workstations.

A sprocket unit comprising: a damper mounted on the first shaft with a first face defining a recess and a second face defining chambers for receiving spring loaded weights; a sprocket mounted to the first shaft with a hub defining an aperture and a slot; a front end plate mounted on the shaft with a hub defining an aperture aligned with the aperture of the sprocket; and a spring received within the aperture of the sprocket, the aperture of the front end plate, and the recess of the damper. When the first shaft rotates and firing frequency of the engine coincides with a resonant frequency of the first shaft, the spring loaded weights slide in the chambers of the damper, dampening out the resonant frequency in the first shaft and when the sprocket rotates the spring compresses and extends, reducing torsional load of the first shaft on the second shaft.

A ski boot sole for cooperating with a ski binding to releasably hold the sole in the binding, the sole having front and rear recesses with front and rear metal inserts. The front recess and the front metal insert are engaged by the front sole holder rotatable about a longitudinal axis for releasably holding the front sole holder against displacement in the forward, sideways and vertical directions. The rear recess and rear metal insert is engageable by the rear binding which is rotatable about a transverse axis. The rear sole holder butts against the portion of the fitting plate extending outside the border of the sole to secure the rear portion of the sole in the rearward, sideways and vertical directions. The front and rear metal inserts are held on the bottom of the ski boot sole by threaded inserts mounted above the sole, with screws extending through aligned holes in the metal inserts and the threaded inserts.
