A long board for street skating having an offset axial joint with a lower hinge support block on a front segment and a lower hinge support block on a rear segment having a hinge which folds the board in the direction of the upper surfaces of each segment, the offset joint allowing a first set of wheels to set behind a second set of wheels depending from each segment when in a folded position for a more compact profile, each lower hinge support block providing the hinge so that each front and rear segment are parallel in a stored and folded position.

A ball joint, particularly an axial joint, having a housing, a bearing shell which is arranged in the housing, and a ball pin with a ball head which is arranged in the bearing shell, is characterized in that the bearing shell is bent open elastically by the ball head so that the restoring force resulting from its deformation applies a prestress onto the ball head which attempts to press the latter out of the housing.

A ball joint, in particular, an axial joint, having a ball stud, which is enclosed in a ball socket. The ball socket is enclosed in a joint housing and is integrally formed having at least one spring element in a region of the ball socket that faces away from the opening of the joint housing. The spring element has discontinuities, in particular in the form of slots, so that wear compensation is created by the spring element within the ball joint.

Fabricate a conformal body interface using a dataset representing a three-dimensional soft tissue body surface. The conformable body interface includes a body frame divided into two or more longitudinal segments separated by an axial joint. Optionally, the body support is further divided into two or more circumferentially separated segments separated by a circumferential joint. The axial joint is constrained circumferentially by an elastic band, sheet or similar structure, and the circumferential joint is constrained longitudinally by an elastic axial tether or similar structure. In this way, the body interface can accommodate swelling and curvature of the body surface.

A foil assembly for a gas powered turbine includes a plurality of floating wall sectors arranged circumferentially about an axis defined by a flowpath. Each of the floating wall sectors includes a first flowpath strut component, a second flowpath strut component, a floating wall panel connected to the first flowpath strut component by a first clamp seal at a first axial joint and connected to the second flowpath strut component by a second clamp seal at a second axial joint, and a plurality of leading edge structures fore of the plurality of floating wall sectors. Each of the leading edge structures is configured to define a foil profile in conjunction with a first flowpath strut component of a first floating wall sector and an adjacent flowpath strut component of a second floating wall sector.

The invention relates to a multifunctional surface aerator. The multifunctional surface aerator comprises a motor, a coupler, a lifting device and a reduction gearbox, the motor drives the reduction gearbox through the coupler, the output end of the reduction gearbox is sequentially connected with an inverted umbrella seat and an impeller shaft, an inverted umbrella impeller and an inverted umbrella conical surface body are installed on the impeller shaft, the portions, corresponding to the conical surface and the horizontal plane of the inverted umbrella conical surface body, of the inverted umbrella impeller are each provided with blades, and the blades all extend outwards; the blades arranged on the portions, corresponding to the horizontal plane of the inverted umbrella conical surface body, of the inverted umbrella impeller are unequal in height, and blades are further arranged on the portions, corresponding to the axial joint of the impeller shaft, of the inverted umbrella impeller. By means of the multifunctional surface aerator, the technical problems that for an existing aerator, the oxygenation efficiency is not high, and the flow-pushing and stirring capacity is poor are solved, and the vast application prospect is achieved.

The invention relates to a method for producing a rack (2) for a steering gear of a motor vehicle, having at least one toothed section (21) with a toothing (22) and at least one shaft section (24) comprising at least one functional section. Separate segments, comprising at least one toothed segment (61) and a shaft segment (62), are provided, the segments are oriented on a common longitudinal axis(L), and the axial joint surfaces (28) of the segment, said joint surfaces being oriented towards one another, are connected together at a welding point by means of friction welding. For the purposesof the friction welding process, the joint surfaces (28) are brought into frictional contact, the segments (61, 62) are rotated relative to each other about the longitudinal axis (L) in order to rubtogether, the joint surfaces (28) are pressed against each other with a pressing force, - the segments (61, 62) are moved towards each other in the axial direction (A) by a specified joining distance(X), and the segments (61, 62) are held in position without rubbing. The aim of the invention is to improve the joining process of segments of a constructed rack. This is achieved according to the invention in that the method has the following steps: rubbing with a pressing force amounting to a rubbing force, rubbing so as to introduce heat with a heat-introducing force which equals 5 to 12 timesthe rubbing force, and pressing the joint surfaces together until the specified joining distance (X) is reached with a welding force which approximately equals 10 to 20 times the rubbing force.
