摘要： In shears for rod-form material, especially in connection to roll trains, the problem exists of a space-saving construction, especially in the sidewise direction, in view of the multiple arrangements, as well as increased safety (reliability) of operation for the high-pressure hydraulic system of the cutting drive.The shear provided with two knife holders (MT1, MT2) and a fluid drive element (ZK) as well as a respective pressure feeding device (DS), is so designed, for this purpose, that the pressure work chambers (DA1, DA2) of the drive element, such as a double-acting cylinder-piston arrangement, and the elements carrying pressure fluid (high-pressure pumps, etc.) of the pressure feeding device (DS) are designed to be movable in common with a knife holder (MT1) which is movable in relation to the machine frame or a conduction (SF) of material to be cut, and preferably fixed in space with this latter (MT1).

摘要： A shear for cutting bar stock includes upper and lower cutting blade supports each having a cutting blade, and a hold-down member, all pivotally connected about a working bearing. This assembly is pivotally mounted about a second bearing or pivot axis on one end of a frame of the shear, and is height-adjustable by a lockable hydraulic actuator attached to the upper cutting blade support at the opposite end of the shear, to provide vertical adjustability of the cutting point with minimal horizontal or angular displacement thereof. Preferably, the two pivot axes and the cutting point are coplanar. The upper cutting blade support is pivoted relative to the lower one by a hydraulic actuator engaging the upper support at one upper part thereof which is not so coplanar, to provide both a relatively long lever arm and a relatively long cutting arm for minimizing arcuation of the cutting movement. One cutting blade is adjustable within its support for optimum positioning taking into account the shape of the stock. The hold-down member is hydraulically locked into position with the lower (thrusting) cutting blade and moves therewith relative to the upper (contact) cutting blade, providing a three-point support to yield a clean cut.

摘要： The heat exchanger element is constructed with radially disposed walls so as to sub-divide the element into flow zones with alternating zones carrying first and second heat-exchange media. The alternating zones convey the media in opposite directions to carry out the heat exchange. The walls may be of flat shape disposed in a radial pattern or may be formed of corrugated plates interspaced between flat walls.

摘要： An apparatus designed especially for mechanically breaking up reinforced concrete and comprising a cylinder containing a hydraulically-operated piston connected to a thrust wedge and acting upon two insertion pieces to be inserted in a borehole in the reinforced concrete or in stone. In order to avoid excessive wear and tear on the components by reducing the stresses to which they are subjected, the apparatus comprises a bracing part rigidly joined to the cylinder by tie plates, and the two end faces of the insertion pieces remote from the cylinder are braced against this bracing part, through which the thrust wedge passes when the apparatus is in operation. Thus the end faces of the insertion pieces can slide on the surface of the bracing part when they are driven apart by the advancing wedge.

摘要： The valve, preferably a dual control valve suitable for high pressure use, has a housing (2) formed with parallel bores in which rotatable valve elements (3,4) are located. The rotatable valve elements are each formed with a blind bore (22,23) coaxial therewith, and defining between an outer surface of the valve element and the blind bore a valve sleeve which communicates via lateral cut-outs (38,39) with inlets (11,12) to the blind bores. Valve sleeve portions (47,46) are left adjacent the cut-outs. The valve housing (2) is formed with outlet openings which can be exposed upon rotation of the valve elements to the remaining valve sleeve portions or to the cut-outs, respectively, to provide, selectively, CLOSED or OPEN positions of the respective valve elements. The housing and the valve elements are made of metal, the valve elements being fitted in the bore with slight amount of play. Pressure applied by a pressure fluid to the inside of the blind bores presses the respective valve sleeve portion against the outlet opening when it is rotated in CLOSED position. The valve elements (3,4) are coupled together for conjoint movement by gears (7,8,9), operated by a hand wheel (5).

摘要： An instantaneous desired cutting position of a milling cutter or circular saw blade in a mobile apparatus for cutting hard materials, such as a concrete highway surface, is maintained even if the mobile apparatus travels over irregular or slanted surfaces. For this purpose the saw blade position is adjustable either by varying the position of the saw blade mounting in a machine frame or by varying the position of the entire machine frame. The position correction is accomplished by a sensor which produces control signals for a position correction power drive in response to pendulum movements which represent cutter or blade deviations from the desired cutting position. The position of the entire machine frame may be varied by raising or lowering a wheel remote from the cutter or blade. Thus, a binding or jamming of the cutter or blade is prevented.

摘要翻译： 即使移动装置在不规则或倾斜的表面上移动，也可以保持用于切割诸如混凝土公路表面等硬质材料的移动装置中的铣刀或圆锯片的瞬时切割位置。 为此，锯片位置可以通过改变机架中的锯片安装位置或改变整个机架的位置来调节。 位置校正通过传感器来实现，该传感器响应于摆动运动而产生用于位置校正功率驱动器的控制信号，该摆动运动表示刀具或叶片偏离所需切割位置。 整个机架的位置可以通过升高或降低远离刀具或刀片的轮来改变。 因此，防止了切割器或刀片的装订或卡住。

The pump unit (3), which can be formed of two or more high-pressure hydraulic pumps and include a cooling water circulating pump (14), has a vertically extending pump shaft (56). The motor shaft and the pump shaft extend through the mounting plate, and a transmission, preferably a belt transmission, is located below the mounting plate. The belt transmission may include a drive pulley which is hollow in the middle, and formed with an internal gear (33) which engages an external, axially curved gear (14') on the motor drive shaft, to form a separable coupling. The motor can be lifted off the cart, and transported separately.

摘要： A rotary cutter saw apparatus (C, B) is movable along an elongated rail element (1). To permit continuous selected longitudinal adjustment of support blocks (8, 34) with respect to a base support suface (S) along the length of elongated rail element (1), an attachment base is formed on the rail element which interfits with a projection-and-recess fit with a portion of the support block. A clamping arrangement (7) can clamp the interengaging projection-and-recess portions together; preferably, they form a dovetail connection, with a movable clamping jaw which clamps both against the attachment base and the support block structure. The support block may include a plate (10), adjustably positioned over the surface by adjustment screw bolts, or a rod or tube element (35), so that the rail element (1) and the cutter element thereon, can also be tilted about the axis of the rod or tube element.

摘要： Recessed grooves are cut into bore hole walls of concrete or rock materials for the purpose of interconnecting two components of such materials at an interface between these components. These recessed grooves are cut by material removing tools which can be pressed radially outwardly, while a drive shaft simultaneously rotates these tools. For this purpose, an axial movement of an adjustment body is converted into a tilting movement of pivotable shafts which carry the material removable tools, whereby the adjustment body is moved linearly by a hydraulic lifting device. The material removing tools extend radially away from the lower ends of the pivotable shaft. The common adjustment movement of all of the pivotable shafts takes place independently of the rotation of the driven shaft.
