The present invention relates to artificial limbs generally and to joints for the same. In particular, the present invention provides hydraulic functional units (35), generally classified as damping devices as connected between artificial limbs whereby to enable movement of artificial joints to closely correspond with natural human movement. In the provision of realistic joints, as used in prosthetic limbs, an important aspect in attempting to achieve a realistic movement is to provide a different operating characteristic to the joint when under load. Indeed, one of the more important characteristics of an artificial leg for achieving a natural-looking walking gait correspond with those of a so called stabilised knee, i.e. a knee which resists flexion when under load, that is when it is bearing at least some of the weight of the amputee. In accordance with the invention, there is provided hydraulic damper control elements for prostheses which utilize a pressure differential due to the presence a fluid flow as a direct control input for a at least one hydraulic valve (47). The valve can comprise a vortex flow arrangement (47f) to cause fluid flow to circulate about aperture. The valve can comprise a moveable element which abuts a resiliently mounted element which reduces the size of an aperture as the force increases.

A bonnet opening is provided on the bonnet, an output end of the high-speed intake and exhaust device penetrates the bonnet opening and is communicated with a high-speed exhaust throttling device for limiting an exhaust amount of gas of the high-speed intake and exhaust device, an output end of the high-speed exhaust throttling device is communicated with an outside air, and a trace exhaust device for discharging the gas separated out from the pipeline to the outside through the high-speed exhaust throttling device after the high-speed intake and exhaust device closes the valve is further provided in the high-speed intake and exhaust device.

A machine tool is provided, in particular for the synchronous machining of workpieces. The tool includes two or more spindle units (2, 3), which run parallel in a machining unit and are designed to hold workpieces and repositioning devices for the precise adjustment of the position of the spindle units (2, 3) in relation to one another, preferably in all three directions x, y and z of the orthogonal co-ordinate system in the machining unit (4). The repositioning devices for displacing at least one of the spindle units (2, 3), at least in an x and/or y direction, include an eccentric bush (5, 6), which can be rotated about a central shaft (B1, B2) and locked and in which the spindle units (2, 3) are mounted eccentrically, parallel to the central shaft (B1, B2).

The invention discloses a magnetic attraction Newton pendulum, and relates to the technical field of toys. The magnetic attraction Newton pendulum comprises a support and at least three lifting ropesarranged on the support side by side at intervals, wherein pendulum balls are arranged at the lower ends of the lifting ropes, and an electromagnetic generator is arranged on one side of the support;and the magnetic attraction Newton pendulum further comprises a control device used for controlling the electromagnetic generator to be powered on and powered off. Compared with the prior art, the magnetic attraction Newton pendulum has the beneficial effects that: the electromagnetic generator and the control device for controlling the electromagnetic generator to be powered on and powered off are arranged on one side of the pendulum balls, the electromagnetic generator is powered on to generate a magnetic field to attract the pendulum balls to move towards one side of the electromagnetic generator, and when the electromagnetic generator is powered off, the pendulum balls move towards the side away from the electromagnetic generator under the action of gravity and inertia, thereby achieving uninterrupted continuous swing.

The invention relates to a roll stand for hot-rolling or cold-rolling metallic strips. Said roll stand comprises back-up rolls and work rolls (2,3; 4,5) which are respectively positioned in chocks (6; 7) in a rotating manner. Each chock (6; 7) can be displaced on two sides in guiding devices (8) of the column frame (9) for adjusting the roll gap (10) and can be additionally displaced on at least one side for adjusting the play, by means of horizontal piston cylinder units (11) arranged in the column frame (9). The aim of the invention is to completely eliminate the play in the vertical guiding device (8) of the work roll chocks (6; 7) during the rolling.
