摘要： The pans of a scraper-chain conveyor are interconnected by way of a dog-bone type connector with enlarged end regions and a central shank which fits into shaped compartments in the side walls of adjacent pans. A hook-like projection on one of the end regions engages in a recess adjoining one of the pockets and a complementary web-like projection on the other end region lies in an opening adjoining the other of the pockets. A swivelling locking plate is fitted to the side wall to overlap the web-like projection and retain the connector in place.

摘要： A cross-axis cutting assembly of a selective cutting machine is provided with internally-fed spray means. The assembly includes two cutting heads supported by a boom, the cutting heads being driven by a shaft which is transverse to the boom. A high pressure water supply line for each cutting head is provided by means of a connecting member. Each connecting member is arranged externally on the boom, is preferably designed as a channelled plate, and closely fits the external contour of the associated cutting head. Each connecting member extends to the free end of the shaft, and is connected to an internal high pressure water duct formed in the associated cutting head by means of a rotary arrangement. Each rotary arrangement has an axial pin which fits sealingly into a passage.

摘要： A conveyor channel section has shaped side walls composed of superimposed rolled profiled strips identical in construction and shape A floor plate extends between the side walls and projects between inclined curved wall portions of upper and lower profiled strips. Longitudinal welds join the floor plate to the ends of the wall portions The wall portions merge with flanges extending inwardly of the floor plate and with ribs extending in an opposite direction outwardly of the floor plate at the level of the flanges. Spill plate holders are welded to the exteriors of the side walls between the ribs and connectors at the ends of the side walls permit adjacent channel sections to be joined together with the aid of coupling members.

摘要： A valve block in a mine hydraulic system contains a non-return valve which is opened when a hydraulic control signal occurs to connect a pressure fluid feed or return line to a working chamber of an appliance such as a prop. A auxiliary valve is mounted in the block and is operated manually to relieve the working chamber even if the non-return valve remains closed.

摘要： A valve device takes the form of a multi-part cartridge with a hollow stepped housing containing a stepped rod. A control piston at one end of the rod is opposed by the force of a main spring in a main chamber remote from the control piston. A valve closure member is axially displaceable relative to the rod. The valve closure member is normally held against a valve seating but pressure on the control piston displaces the rod and causes the valve closure member to be lifted from its seating via stop faces. An auxiliary chamber in the housing leads via a connection to some consumer appliance and forms, the downstream side of the valve. A compensating piston on the rod member opposes a face of the valve closure member open to the auxiliary chamber. A further spring in the auxiliary chamber holds the valve closure member on its seating. The valve can open independently of the control piston should the pressure on the upstream side of the valve exceed the consumer pressure. This upstream side usually leads to either the pressure line or a return line as determined for example, by a change-over valve. The valve closure member will respond reliably to increased pressure on the control piston which only has to overcome predetermined spring force independent of hydraulic pressure in the auxiliary chamber.
摘要翻译：阀装置采用具有中空阶梯式壳体的多部分筒形的形式，其包含阶梯式杆。杆的一端处的控制活塞与远离控制活塞的主室中的主弹簧的力相对。阀关闭构件可相对于杆轴向移动。阀关闭构件通常保持在阀座上，但是控制活塞上的压力使杆移位，并使阀关闭构件通过止动面从其座上抬起。壳体中的辅助室通过与一些消费者用具的连接引出，形成阀的下游侧。杆构件上的补偿活塞与通向辅助室的阀门关闭构件的面相对。辅助室中的另一弹簧将阀关闭构件保持在其座上。如果阀门上游侧的压力超过使用者的压力，阀门可独立于控制活塞打开。该上游侧通常通过例如通过转换阀确定的压力线或返回线。阀关闭构件将可靠地响应于控制活塞上的增加的压力，其仅需要克服与辅助室中的液压无关的预定弹簧力。

摘要： A drive system for driving an endless chain of a mineral mining installation employs one or more chain wheels each driven by an electric motor and gearing including planetary gearing. The planetary gearing has a ring gear which can be held stationary to permit drive to be transmitted. The ring gear is coupled through a clutch, reduction gearing and a braking device to another load-balancing electric motor. Load sensors in the reduction gearing disengage the clutch in the event of overloading. The ring gear is automatically held stationary by the braking device when the load-balancing motor is inoperative. When the motor is switched on the braking device is released to permit the motor to rotate the ring gear in one direction or the other at controlled speed to vary the transmission ratio and effect load balancing.

摘要： A valve device has a multi-part housing containing a servo-valve with a stem which is axially displaced to operate the valve and an electromagnet with a rod-like armature which is axially displaced when the electromagnet is energized. A pivotable lever translates the axial movement of the armature to the stem. For adjustment purpose, an adjustment member is in screw-threaded engagement with the lever remote from the stem. The armature is locked for rotation with the adjustment member. A regulator at the opposite end of the armature to the lever and accessible from the exterior serves to enable the armature to be partially rotated for effecting the adjustment.

摘要： An electro-hydraulic control system has a valve unit allocated to a roof support (support shield, support trestle or the like) and equipped with electromagnetic valves. The unit is controlled by a control unit via a cable which includes two current supply leads serving as a common current supply for all the electromagnetic valves and at least one data bus through which an actuator connected with the valve unit is actuated from a microprocessor of the control unit. The actuator itself consists preferably of a shift register through which all the electromagnetic valves can be actuated.

摘要： A data transmission/reception system usable for bi-directional data transmission in electro-hydraulic control systems between two adjacent supports of a mine installation which each have their own transmitting and receiving stations in a control unit. Bi-directional data exchange takes place via a single wire data bus which is used for simultaneous transmission and reception and forms the summation point for adding the transmitted signals from two transmitters. Each transmitting and receiving station is provided with a subtraction circuit connected to a receiver of the respective transmitting and receiving stations and to which the transmitted signals from its own transmitter are supplied in each case at the subtraction circuit input. The other input of the subtraction circuit is connected to the bi-directional data bus. In this way, a duplex connection between the two transmitting and receiving stations is created in which the transmitted signals from one transmitter is subtracted from two-way transmissions at the associated receiver.
