The conveyor pan according to the present invention has a framework construction (1) having the bottom run (2) and an interchangeably constructed exchangeable tray (4) forming the top run (3), which can be lifted out, vertically supported on the framework (1). The framework construction (1) of the conveyor pan (50) has two roiled U-profiles forming the side walls of the conveyor pan, each of which has a vertically extending intermediate arm (11), an upper, outwards facing flange arm (12) and, lower outwards facing flange arm (13). The identically constructed but mirror imaged iron U-profiles (10), i.e. with the flange arms (12), (13) arranged facing away from each other, are joined firmly to each other by means of welded on plate strips (5A, 5B) at about half height on the inner wall (14) of the intermediate arm (11), whereby the plate strips (5A, 5B) leave an opening (6) inside the conveyor pan (50), which, with the exchangeable tray (4) removed, can serve as an inspection opening for the scraper chain, not shown, circulating in the bottom run (2) and equipped with scrapers. In the free space between the flange arms (12, 13) toggle pockets are welded in with a positive engagement, which additionally stiffen the iron U-profiles and the plate strips (5A, 5B) are supported by means of bottom run rails (20) on a continuous base plate (7) welded on beneath the iron U-profile (10).

A multiple-lumen access sheath for use with an endoscopic or laparoscopic device. The sheath includes a flared funnel on a proximal end of the access sheath for ease of handling by a user. The sheath also includes an elongated portion extending from the funnel to a distal end of the sheath, the elongated portion comprising a first lumen and at least one additional lumen for substantially the length of the elongated portion. There is also an interface for the at least one additional lumen on the proximal end.

A foot pedal irrigation system allows a physician or other operating person to control the flow of irrigation fluid to a diagnostic or therapeutic device without using the physician's hands. The system attaches to one or more bags of irrigation fluid and uses clamps on inlet and output tubing. The system may include a visual drip chamber to monitor fluid flow without applying pressure to a foot pump which is part of the system. When increased irrigation is desired, the physician presses with a foot on the foot pedal pump; one way valves assure the increased one-way flow of fluid from the pump to the diagnostic or therapeutic device.

The invention relates to a polarizer (1) for electromagnetic radiation. The polarizer (1) has electrically conductive elements (5, 24) arranged in parallel and it a given distance from each other. The elements (5, 24) are held in position by at least one spacer (3, 7, 9, 23). Each spacer (3, 7, 9, 23) is made of a low dielectric material.

A drying device for drying bulk material has one or more storage containers for the bulk material and a heating device for heating the drying air for drying the bulk material. A drying air conduit is connected to the heating device and the storage containers and guides the drying air to the storage containers. One or more first mixing valves are arranged in the drying air conduit upstream of the storage containers, wherein the first mixing valves are used to adjust the temperature of the drying air before the drying air enters the storage containers. The heating device has also the function of regenerating the drying units provided for removing the moisture from the drying air.

The guide shoe according to the invention for cutting machines with a pintype drive has an insertion pocket in which a coupling piece engages from above, which coupling piece is arranged on a guide arm of the cutting machine and to which the guide shoe is attached so as to be pivotable by means of a transverse bolt which passes through the insertion pocket. In order also to allow the guide shoe to be pivotable about a vertical axis, the coupling piece is provided with an upright vertical journal which engages from below in a corresponding bearing hole on the guide arm. In this case, in a preferred embodiment, the bearing journal is decoupled from transverse forces which are transmitted between the guide arm and the guide shoe via a transverse-force piece arranged on the coupling piece.
摘要:
A conveyor chute for chain scraper conveyors, in particular stope conveyors, having a bottom aperture provided in the conveyor bottom forming an inspection or repair aperture and closed by way of a closure panel during the conveying operation. The closure panel is guided in slot-shaped apertures of the two side profiles of the conveyor chute by way of their opposite panel edges and secured against displacement by a locking device. The two side profiles of the conveyor chute are each formed of two profile strips in superimposed array which are not interconnected to the conveyor bottom in the region of the bottom aperture. The two side profiles form the slot-shaped apertures in which the locking of the closure panel in the closed position takes place only on one of the two side profiles.

The invention relates to a multipart chain fixing device for securing at least one conveyor chain on a trough element of especially an underground scraper chain conveyor. The fixing device comprises a bridge part (60), which has a bridge bar (62) that at least partially overlaps the conveyor chain in a positive-locking manner and ends in two lateral side end portions (61). It also comprises two side parts (70), which are fastenable to the trough element pan and to which the side end portions 61 are releasably securable by positive-locking means. For providing a chain fixing device, inclusive of the associated trough element and the individual components, which offer increased safety in underground usage, combined with simple assembly, the side parts (70) are releasably fastenable in a positive-locking manner in cavities in the conveyor floor of the trough element.
