摘要： A video terminal has a housing composed of a basic housing encompassing a back portion of a picture tube and a frame encompassing a picture area of the tube. The basic housing is uniformly designed for a plurality of picture tubes of different sizes and variously designed frames are adapted to the basic housing in accordance with a respective picture tube. The frames are preferably secured to support mounts fixed to the frame which are disposed in said basic housing. Given an axially symmetrical design of said support mounts, the frame with said picture tube is optionally insertable either horizontally or vertically. The frame can be formed of one or more parts. The parts of the frame and/or of the frames and the basic housing can be connected to one another by snap-in closures.

摘要： A self-advancing mine roof support has a beam-like abutment adapted to be disposed generally adjacent and parallel to a work face. Three roof support elements are spaced apart along the abutment and are pivoted to the abutment. The abutment may be angled relative to the direction of advance by arranging the three support elements in staggered formation. A beam of the central support element is pivoted to the abutment. The two outer roof support elements are connected to the abutment by a linkage, e.g., guide arms, which allows the abutment to pivot about the beam of the central element without changing the distance between the three elements as measured at right angles to the direction of advance.

摘要： The roof-engaging assembly of a support frame for a mine roof comprises a main beam having a cantilever extension pivoted to the main beam by pins. In order to pivot the cantilever extension through an angle of about 180.degree.-200.degree. between a stowed position and an operative position, a link is pivoted at one point to the main beam and is pivoted at another point to one end of a double acting jack. The other end of the jack is pivoted to the main beam so that, by extending or retracting the jack, the link member pivots one way or the other. The cantilever extension has a pin which runs in a slot in the link member, the arrangement being such that pivoting of the link member by the jack produces pivoting of the cantilever extension through a much larger angle, e.g., double the angle.

摘要： In a method of mining coal seams using a ploughing cutter, a longwall conveyor extending along the coal face is moved forwards by the extension of self-advancing cylinders, the advance being controlled in dependence on a piston stroke of a respective self-advancing cylinder and being made in individual defined partial strokes using travel-measuring signals generated at each partial stroke. The distance covered by the partial strokes corresponds to the preset depth of cutting and is increased by an amount sufficient to compensate an average mechanical clearance at the pivot points of the self-advancing cylinders. In addition, a defined face line is fixed with respect to a center of rotation on the side of a main or auxiliary drive of the cutter so as to form a straight line through the center of rotation, the straight line being pivoted through an angle

摘要： A control system for longwall face support frames as used in mines, the system comprising pushing rams which are adapted to be actuated at two different pressures (for example, a low pressure of about 70 to 120 bar for non-defined cutting and a high pressure of 120 to 350 bar for defined cutting) with each pushing ram being individually actuatable by a respective non-return valve arrangement, the pushing rams being connected by a common pressure line to an hydraulic pressure unit.

摘要： A 3-port, 2-position, directional control valve has two cylindrical closure elements for the alternate connection of a control line to a return flow line and a high pressure line. The switching force exerted on a thrust member is transmitted via pressure pins, and a manifold member with a centrally-positioned axial bore connected to the control line is arranged between the closure elements. Sealing elements on the closure elements seal the exit openings of the bore in the manifold member alternately. One of the pressure pins extends through the manifold member eccentrically while extending parallel to the axial bore and is always under pressure, like the high-pressure-side closure element, so that the closure element on the low pressure side is always held open in the zero position of the valve while the closure element on the high pressure side is acted on by the pressure medium in the direction of closure. The switching force required to open the valve is small because the pressurized cross-sections of the axial bore and the pressure pin are constructed to be small.

摘要： The support assembly is made up of a floor-standing runner member 1, a hydraulically vertically-adjustable prop 2 mounted on the same, a roof canopy 3 supported by the same and a rockfall shield 4 hinged to the same on the backfill side which is guided to be pivotable in a vertical plane by two direction-control members 5 and 6 articulated to the runner member so as to be spaced apart one behind the other. The front direction-control member 6 is constructed as a hydraulic thrust piston mechanism. Via a control circuit 8 the hydraulic control valve 7 of the direction-control member 6 is connected to measuring devices 9 usable to measure the position of at least two mutually variably spaced apart support assembly reference points. If the reference points deviate from the preset normal position of the support assembly, pressure fluid acts on the front direction-control member 6 via the control circuit 8 until the normal position has been regained.

摘要： An hydraulic walking roof-support frame for a coal mine has a roof support assembly comprising a main support and an auxiliary support pivotally connected to the main support for pivoting about a horizontal axis through an angle of 180.degree.. The auxiliary support is caused to pivot by a pair of hydraulically operated extensible and retractable jacks connected between the main support and the auxiliary support, the pivot points where the jacks are connected to the auxiliary support being angularly spaced apart relative to the axis of pivoting of the auxiliary support whereby when (during pivoting of the auxiliary support) one jack is in a "dead center" position the other jack can still pivot the auxiliary support permitting remote control thereof.
