Abstract: A rack serving unit comprises a carriage which may be moved along a rack aisle on substantially horizontal carrying rails. Carried along by the carriage there is a lifting platform which is suspended on the carriage by way of at least two traction mechanisms, preferably cables, and may be moved in the vertical direction with respect to the carriage. To stabilise the lifting platform against undesired lateral movements, a stabilising device is provided which comprises at least one guide element extending substantially horizontally parallel to the translatory movement path of the lifting platform. This guide element is in constant engagement with the lifting platform in such a way that the position of this latter in the direction of the translatory movement is constantly defined. Provided at both ends of the translatory movement path, there is a lifting device for each guide element by means of which the guide element may be moved synchronously with the lifting platform in the vertical direction.

Abstract: The invention relates to a method for sintering aluminium-based sintered parts which are, initially, guided with the aid of a transport system T through a de-binding area (3) before being guided through followed by a sintering area (2) and finally being guided through a cooling area (4).

After passage of the carrier arm, the spring strips return to a sealing position.

Abstract: An installation for coating objects with powder, in particular for powder painting, comprises a booth which is known per se and in which powder can be applied to the objects by an application device. Stray powder is entrained by an air stream directed through the interior of the booth from the top downwards. The mixture of air and powder is extracted via an extraction opening in the bottom of the booth and supplied to a movable filter unit which is situated beneath the extraction opening and in which the powder is separated from the air/powder mixture for reuse. A plurality of such movable filter units are movable while suspended from a supporting-rail system, it being possible for all of these filter units, which are each intended for separating off a particular type of powder in particular one powder paint color, to be selectively brought under the extraction opening of the booth.

Abstract: An installation for treating, in particular coating, articles, especially vehicle bodies, comprises at least one bath, in which a treatment liquid, in particular a paint, is located. The articles are intended to be immersed therein. A conveyor with which the articles are conveyed through the installation in a continuous or intermittent translational movement comprises a plurality of transport carriages, which run in guided manner on running surfaces. Each transport carriage comprises a separate drive for translational movement and a drive operating independently thereof for the immersion movement. The installation thus constructed is extraordinarily flexible, since the immersion movement does not have to correlate with the translational movement.

Abstract: The invention relates to an electric overhead conveyer comprising a large number of carriages (8), which circulate on a running rail system (1). Each carriage (8) has an autonomous carriage control (11), whose memory stores (13) all the data for the rail network. The overhead conveyer can either be operated in individual circulation mode, in which each carriage (8) attempts to travel individually at the greatest permissible speed, or in group mode. In group mode, the carriages (8), which are to traverse a common section of the rail network (1) are combined into groups and exchange data concerning the locally permissible speeds that are respectively valid. All the carriages (8) in the group then travel at a speed that corresponds to the lowest permissible speed for all carriages (8) in the group.

Abstract: Objects, (4) especially vehicle bodies (4), are guided through a painting installation comprising at least one bath (2) in a continuous translation movement, by means of a transport device (5). Immersion devices carry the objects using a carrier structure (61) which is connected to the transport device (5) in such a way that it can be pivoted by a pivoting arm (50, 51). A first drive device (54, 55, 56, 57) causes a pivoting movement of the pivoting arm (50, 51) about a first axis. A second drive device (78, 79, 80, 81) is used to pivot the carrier structure (61) about the second axis, in relation to the pivoting arm (50, 51). One such immersion device enables very different kinematics of the immersing and emerging movement to be carried out.

Abstract: In order to regenerate the heat exchanger material located in the various segments of a housing section (2) of a regenerative post-combustion device (1), air is heated in the combustion chamber (8) of this post-combustion device (1) by a burner (9), is directly removed from the combustion chamber (8), is adjusted to the desired regeneration air temperature using fresh air, and is returned to the inlet (4) of the thermal post-combustion device (1). The outlet (10) of the thermal post-combustion device (1) remains closed during this operation. The rotary distributor (5) of the thermal post-combustion device (1) rotates during this process which is continued until all segments of the heat exchanger material are heated to a temperature at which the contaminants absorbed by the heat exchanger materials are released and combusted in the combustion chamber (8).

Abstract: A regenerative post-combustion apparatus (1) in a housing (2) in a known manner comprises from top to bottom a combustion chamber (8), a heat exchanger area (7) subdivided into a plurality of segments filled with heat exchanger material, and a rotating distributor (5). The latter depending on its rotational position establishes a connection, on the one hand, between an inlet (3) for waste gas to be cleaned and at least one first segment of the heat exchanger area (7), as well as between at least one second segment of the heat exchanger area (7) and an outlet (10) for cleaned gas. Disposed above the rotating distributor (5) is a burn-out rotary slide valve (31). The latter is subdivided by dividing walls into segments, of which one is closed in the direction of the rotating distributor (5) and communicates with an outlet (68). The other segments of the burn-out rotary slide valve (31) are open in a downward and an upward direction.

Abstract: A transport system for the shell assembly of vehicle bodies comprises a rail system (2, 3) which connects at least two processing stations and on which at least one carriage (4), which carries the workpiece, is capable of travelling. The guidance of the carriage (4) on the rail system (2, 3) and/or the design of the said carriage permits a certain displacement of the carriage (4) transversely to the direction of movement and in the vertical direction. Disposed in the processing stations are spatially fixed positioning means (13a, 13b, 17a, 17b, 31) which cooperate with corresponding positioning means (10a, 10b, 15a, 15b, 16, 28) on the carriage and shift the carriage (4), without having recourse to any other driving source than the movement of the carriage (4) itself in the processing station, into the exact position which is necessary for processing the workpiece in the said processing station.

Abstract: The invention relates to a method for disposing of hazardous or high-energy materials, in which the latter are caused to undergo a reaction in a pressure-proof housing under controlled conditions, the end products of which reaction are non-hazardous, as well as an apparatus for disposing of hazardous or high-energy materials with a pressure-proof housing in which the materials may be caused to undergo a reaction under controlled conditions, the end products of which reaction are non-hazardous.

Abstract: In order to regenerate the heat exchanger material located in the various segments of a housing section (2) of a regenerative post-combustion device (1), fresh air is fed via the flushing air connection (11) into the combustion chamber (8) of this post-combustion device (1), is heated there by a burner (9), and is fed to the rotary distributor (5) via a segment of the heat exchanger material. Heated air which, when passing through the heat exchanger material has picked up contaminants deposited thereon is fed to the inlet or outlet connection (4, 10) of the post-combustion device (1) via the rotary distributor (5) and, from there, is introduced once again into the combustion chamber (8). The rotary distributor (5) of the thermal post-combustion device (1) stops during this process which is continued until the heat exchanger material is heated to a temperature at which the contaminants absorbed by the heat exchanger material are released and combusted in the combustion chamber (8).

Abstract: The invention relates to a power & free conveyor which comprises a free rail (3) and a power chain (1) that follows said free rail (3), to a large extent, in a parallel manner. A transport carriage (4) provided with a front runner (5) and a rear runner (6) are arranged on the free rail (3). The front runner (5) and the rear runner (6) each comprise a carrier (11, 14) that can pivot between two positions. In an area of the movement path of the transport carriage (4), the course of the power chain (1) deviates from that of the free rail (3) so that the transport carriages (4) can no longer be moved via the front runner carrier (1) thereof. Instead, the transport carriage is pushed by the interaction between a chain carrier (2) and the rear runner carrier (14) that is swung out into a carrying position. The rear runner carrier (14) comprises two stabile positions which can be changed by overcoming a resistance.
