摘要： The invention relates to a connecting element (10) having a hollow-cylindrical shaft (12) and a drive (16), via which the shaft (12) can be driven in a direction of rotation, wherein the hollow-cylindrical shaft (12) has at least one free end, wherein the drive (16) is arranged opposite the free end, wherein a hollow space is formed by the hollow-cylindrical shaft (12). The invention is characterized in that driver structures (22) acting in the circumferential direction of the hollow-cylindrical shaft (12) are arranged in the hollow space, which, projected on the lateral surface, are arranged to extend in the setting direction on the lateral surface, rectilinearly parallel to the element mid-axis (M) or with an angular deviation of at most 20° with respect to the element mid-axis (M), and/or are arranged at the end on the drive side.

摘要： A continuous strip of T-Nuts formed on a common strip of metal. Each T-Nut of the strip of T-Nuts is integrally connected to the next adjacent T-Nut by carry tabs. The carry tabs can be frangible themselves or contain a frangible portion. Each T-Nut includes a cylindrical bore therein and a threaded interior. A mechanism feeds and severs the endmost T-Nut in endwise fashion. The mechanism to feed and sever the endmost T-Nut includes a cutting blade positioned vertically below the frangible portion of the carry tab. A shearing ram having a guide positioned axially in line with the cylindrical bore in the endmost T-Nut is adapted to move vertically from an upper to a lower position to engage the cutting blade with the frangible portion and sever the endmost T-Nut.

摘要： The invention relates to a feeding system (10) having a feeding apparatus (30) for conveying laboratory vessels for samples, microorganisms, cell cultures or the like, and a carrier (12) having one or plural holders (16) for storing laboratory vessels, which feeding apparatus (30) has a loading area (36) and an unloading area (46) remote from the loading area (36) in which plural laboratory vessels can be stored in a vertically stacked configuration, with each receiving unit (34) being coupled to an endless conveyor unit (38) which transports the receiving unit (34) from the loading area (36) to the unloading area (46), and in which the carrier (12) can be used to introduce laboratory vessels into one or plural receiving units (34) in the loading area (36), for which purpose the carrier (12) is at least partially slid over the at least one receiving unit (34) which is to be loaded or unloaded, and for this purpose has projections (28, 32) and/or recesses that are associated with the carrier (12) and are provided in the loading area (36) of the feeding apparatus (30), which will result in positive locking of the feeding apparatus (30) and the carrier (12) when the carrier (12) has been inserted in the loading area (36). According to the invention, the carrier (12) has at least two holders (16) and the positive locking of the carrier (12) and the receiving unit (34) in the loading area (36) of the feeding apparatus (30) will allow only a single predefined orientation of the carrier (12) in the loading area (36).

摘要： The invention relates to a connecting element (10, 20, 30, 50) for producing a component connection (70) of two components (72, 74; 92) lying against each other by means of the connecting element (10, 20, 30, 50), which is welded to the lower layer (74)—the base layer—by friction, wherein the connecting element (10, 20, 30, 50) has a shaft (18), which has a shaft segment (14) and a head (12) having a flat surface (20) lying on the top side of the head for transmitting the axial force, wherein a drive cutout (22, 32) is introduced into the flat surface (20) in order to transmit a torque. The invention is characterized in that a continuous diameter increase starting at an ascent level (A) on the shaft segment (18) to the bottom side of the head results, wherein the distance from the ascent level (A) to a head bottom-side level (K), which has the greatest distance from the shaft end, is less than half the difference between the head outside diameter and the shaft diameter at the ascent level (DA−DS)/2 (D2) and greater than a quarter of the difference between the head outside diameter and the shaft diameter at the ascent level (DA−DS)/4 (D1).

摘要： An aerial rope tramway or slope hoist system suitable for use in an open pit mine or similar application. According to an embodiment, the aerial slope hoist system comprises an upper station and a lower station. The upper station is configured in proximity to a surface section of the open pit and the lower station is configured at a lower section of the open pit mine. According to an embodiment, the upper station comprises first and second towers and the lower station comprises first and second towers. The towers are configured to support respective ends of first and second suspension cable assemblies. Each of the suspension cable assemblies is configured to support and carry a trolley or skip. The system comprises a hoist configured to move the respective trolleys in opposite directions. The towers for the lower station are configured to be moveable and provide the capability to break down the system and/or lengthen or reduce the span of the system.
