摘要： A shaking control unit for a hydraulic cylinder, wherein a first predetermined pressure is admitted to the piston space of the cylinder through a first hydraulic line. A three/two-way valve connects in its zero position a second hydraulic line to a return tank, the second hydraulic line being connected to the first hydraulic line through a check valve. A first control line leads from the first hydraulic line to a first control area of the three/two-way valve. A second control line leads from the second hydraulic line to a second control area of the three/two-way valve. The three/two-way valve is constructed in such a way that, when the pressure in the first hydraulic line reaches a second predetermined pressure which is greater than the first predetermined pressure, the three/two-way valve switches and connects the first hydraulic line to the second hydraulic line. If the piston of the hydraulic cylinder meets an obstacle, the pressure in the first hydraulic line rises above a certain limit value. This pressure acts on the first control area of the valve and switches the valve, so that the high pressure of the first line becomes suddenly effective in the piston space through the valve and the second line. This pressure switches back the valve after a certain period of time over the second control line.

摘要： The pressure sensor has a mechanical pressure receiving member and a mechanical-electrical transducer connected to it. The transducer comprises a permanent magnet attached with a moving portion of the pressure receiving member which cooperates with a locally fixed Hall-effect sensor mounted on the housing. To linearize the characteristic response curve of the transducer the inner surface of the housing wall is shaped like a funnel in a region between the permenent magnet and the Hall-effect sensor and in the vicinity of the permanent magnet. Because of this geometry the field strength lines are bunched increasingly on increasing separation of the permanent magnet from the Hall-effect sensor so that the field strength at the Hall-effect sensor increases and/or decreases approximately linearly with displacement path of the magnet.

摘要： An apparatus for the contactless measurement of geometrical dimensions includes a light source emitting a light beam, a first deflector deflecting the light beam at an angle toward an object to be measured, a receiver receiving the light beam and a second deflector for deflecting the light beam reflected by the object toward the receiver. The second deflector rotates about an axis extending perpendicularly to the light beam reflected by the object. The axis of the light beam emitted by the light source extends parallel to the axis of rotation of the second deflector. The light beam conducted to the receiver extends coaxially to the axis or rotation of the second deflector. This apparatus requires no calibration, but only an adjustment. For measuring a distance it is sufficient if only the second deflector rotates. If both deflectors rotate, the second deflector must rotate at a substantially higher rate of rotation than the first deflector. The first deflector is vertically adjustable and lockable. Also, the unit formed by the light source, the two deflectors and the receiver may be rotatable about an axis and movable in longitudinal direction of the axis extending parallel to the axis of rotation of the second deflector.
摘要翻译：用于非接触测量几何尺寸的装置包括发射光束的光源，使一束角度朝向待测物体偏转的第一偏转器，接收光束的接收器和用于偏转光束的第二偏转器被物体反射到接收器。第二偏转器围绕垂直于被物体反射的光束延伸的轴旋转。由光源发射的光束的轴线平行于第二偏转器的旋转轴线延伸。传导到接收器的光束与第二偏转器的轴线或旋转同轴地延伸。该装置不需要校准，而只需要调整。为了测量距离，只有第二偏转器旋转就足够了。如果两个偏转器都旋转，则第二偏转器必须以比第一偏转器显着更高的旋转速度旋转。第一个导流板可垂直调节和锁定。而且，由光源形成的单元，两个偏转器和接收器可以围绕轴线旋转，并且可在平行于第二偏转器的旋转轴线延伸的轴线的纵向方向上移动。

摘要： The apparatus for removing stratified outcropped minerals and for transporting these minerals parallel to the mining face or breast comprises a digging portion and a conveyor portion as well as a chain conveyor guided positively in them with digging tools and carrier members. The digging portion and the conveyor portion are assembled together from a plurality of pan-like members. Each pan of the conveyor portion comprises a conveying trough made from two guide pieces which are mirror images of each other attached to a base plate and from two identical bent plates. The guide pieces engage in members in the bent plates and are clamped with them by clamping plates on the top side of the bent plates. The digging portion has a guide piece indentical with the guide piece of the conveyor portion. A basin-like plate of the digging portion is pivotably mounted by a welded substantially circular cross section strip on the breast wall side of the conveyor portion. Coupling members for the adjacent pan-like members of the conveyor portion are located under the bent plates.
