Abstract: A semimobile crusher plant as well as a process for displacing and supporting a semimobile crusher plant are disclosed. The semimobile crusher plant is permanently connected to a crawler-type chassis that has double crawlers, on which the entire load of the crusher plant rests during the displacing. During the crusher operation, the entire load of the crusher plant, including a payload, is supported by means of support rockers more or less equally on the double crawlers of the crawler-type chassis and on foundation blocks provided at the operating sites of the crusher.

Abstract: A dumping system, for the dumping of material, in particular for the filling of a former strip mine, includes a conveyor belt with belt modules (7) suspended on cables and a traveling tripper (15), which is arranged traveling in the direction of conveying. The belt modules (7) are fastened by braced carrier cables (3) and suspension cables (5) fastened thereto in a mostly horizontal alignment. The traveling tripper (5) can travel on the belt modules (7). Furthermore, the slack of the carrier cables (3) may be compensated by a different length of the suspension cables (5), such that the belt modules (7) are aligned mostly horizontally. It is thus possible to span over the area to be dumped (for example, a pit) with cables and to dump material by the traveling tripper at all points of the bracing. Thus, it is not necessary to drive the dumped material.

Abstract: A compact spreader on continuous tracks (10) for use in opencast mining has a discharge boom (70) with a rearward extension designed as a rocker having a counterweight (100). The rocker is suspended centrally in a framework (50) over the turntable (40). Hydraulic cylinders (14) absorb only forces from half of the imposed load. The embodiment according to the invention is suitable for large band widths and discharge projections up to 100 m and eliminates the danger of tipping over.

Abstract: A mobile crusher (2) is provided that can be displaced on four caterpillars and that includes a supporting frame (20), a large hopper (31), an apron conveyor (32), a sizer (34) and an intermediate conveyor (36) for use in strip-mining. The material is received by the shovel (1) of a shovel excavator or a wheel loader, is fed to the crusher (2), crushed and is then transferred onto a conveyor plant via a discharge conveyor system. The crusher (2) has to follow at the same cycle in which the shovel excavator moves forward during an advance in mining. In order to obtain a good maneuverability of the crusher (2), the two front caterpillars (22) are driven and can be steered like a two-caterpillar chassis. As the crusher (2) is subject to high loads, all components have to have a robust design. For this purpose, the individual functional groups are accommodated in a stable supporting frame (20).

Abstract: A conveyor belt system drive has at least one drive at the head drum or head drums. At least one non-driven relieving roller is arranged in a vicinity of each of the driven upper belt middle rollers. A device brings the driven upper belt middle rollers into a position spaced a distance from the belt. The driven upper belt middle rollers can be removed from the belt for maintenance operations or replacement. It is not necessary to stop the conveyor belt system in case of a defect of a driven upper belt middle roller to repair or replace same. The non-driven relieving roller advantageously assumes the support function of the driven upper belt middle roller, when this is located in the position spaced at a distance from the belt. The driving power of the conveyor belt system is dimensioned such that failure a driven upper belt middle roller can be compensated.

Abstract: A method for forming a longitudinal edge region of a transport/drive belt having at least two layers of a thermoplastic material and at least one layer of a woven fabric web includes positioning a mat at one longitudinal edge of the transport/drive belt. The method further includes transferring heat and pressure to the transport/drive belt so as to melt and merge at least a region of the at least two layers of thermoplastic material without adding any additional material, solidifying the at least two layers of thermoplastic material, and removing the mat.

Abstract: Provided herein are carbohydrate complement-modified bifunctional glycoproteins, and their use in tumor-selective therapy. The bifunctional glycoproteins comprise a first component that specifically binds to a tumor-specific antigen and a second component having enzymatic activity by means of which a non-toxic prodrug is cleaved into a cytotoxic drug. The carbohydrate complement comprises at least one exposed carbohydrate residue selected from the group consisting of mannose, galactose, N-acetylglucosamine, N-acetyllactose, glucose and fucose. The modified carbohydrate complement contributes to increased relative concentration of the glycoproteins at the site of the tumor, and enhanced clearance from the general circulation and non-tumor sites.

Abstract: The invention relates to a method for contactlessly and dynamically detecting the profile of a solid body. At least one light beam is generated by a laser device and expanded to form a linear light band projected onto the moving surface of the solid body. Light reflected from the surface of the solid body is focused in an imaging device whose optical axis is at a fixed triangulation angle to the direction of projection of the laser device and which is arranged at a fixed based distance from the laser device. The reflected light is detected by a planar light receiving element at a frequency that is high by comparison with a speed of movement (v) of the solid body after which the measured values of the profile are obtained as a function of the triangulation angle and the base distance.

Abstract: The present invention relates to a method for contactless dynamic detection of the profile of a solid body, particularly a moving one, a laser beam, expanded to form a linear light band, from a laser device being projected onto a region of the surface of the solid body, and the light reflected therefrom being focused in an imaging device, whose optical axis is at a fixed triangulation angle to the projection direction of the laser device and that is arranged at a fixed base distance from the laser device, and is detected by means of a planar light receiving element, in particular at a frequency that is high by compariosn with a speed of movement of the solid body, whereupon signals output by the light receiving element are used in a data processing device as a function of the triangulation angle and the base distance to obtain the measured values of the profile by means of geometric relationships, the values being stored as a profilogram.

Abstract: To leach the metal, crushed ore must be dumped in relatively thin layers of a height of approx. 5 m to 10 m. A conveying and stacking system, including a movable conveyor belt system, traveling tripper and stacker is used for this. The movable conveyor belt system is formed by a plurality of individual belts, the so-called grasshoppers. Provisions are made in the dumping technology for a high block for the end device in the conveying chain, the stacker with its swingable stacker boom, to always discharge an arc-shaped layer of ore, after which the device moves back by the amount of the next layer to be discharged in an arc-shaped pattern. This process is repeated until the stacker has moved back by the effective length of a grasshopper. Conveying is then stopped, one grasshopper is removed from the conveyor belt system and dumping of the ore is then continued. To enable this technology to be used, the stacker must be provided with a material pickup area, which is as long as a grasshopper.
