Abstract: The invention relates to a supporting roller set for tiltable, axially movable and rotatable support for a rotary drum which can be driven in rotation. It comprises two supporting rollers which lie symmetrically on both sides of a vertical longitudinal central plane of the rotary drum and are each mounted in two rotary bearings which are fixed on bedplate which is tiltably supported on a static foundation. In order to be able to achieve an optimal self-adjustment with easy action of each supporting roller, each bedplate is supported by way of two articulated bearings disposed at a transverse spacing from one another on the foundation, of which the inner articulated bearing is constructed in the form of a ball-and-socket bearing, whilst the outer articulated bearing forms a movable bearing and is supported on the foundation so as to be slidably movable about the central point of the ball of the inner articulated bearing.

Abstract: A supporting roller bearing for a rotary drum comprises a supporting roller, supporting on its outer surface a circumferential running surface of the rotary drum. The supporting roller is mounted with axial clearance. A measuring device determines the particular axial position of the supporting roller and is connected by way of a control unit to an adjusting arrangement to alter the angle between the axis of the supporting roller and the axis of the rotary drum as a function of the measured axial position of the supporting roller.

Abstract: A stimulation device for the determination of the temperature perception of the skin of a patient by means of a stimulator, which is arranged in a casing and which can be heated up or cooled down by a Peltier element. The stimulator (1) is arranged moveably along an axis (5) in the casing (4) and shows a projection (14) in relation to the casing (4) in the starting position. A first pressure device (6) cooperates with said stimulator (1) in such a way that said stimulator (1) can be shifted along said axis (5) by expenditure of force until said projection (14) is at zero. The force is predefined or adjustable by said first pressure device (6).

Abstract: A rotary drum having a toothed rim arranged on the drum casing and supported at several peripheral points on the drum casing by evenly distributed bridge members. Each bridge member includes two clips axially spaced from one another and welded to the drum casing and a cross plate which connects the clips and is radially spaced from the drum casing. Each cross plate is rigidly connected to one clip and slideably connected in the axial direction to the other clip so that differing degrees of thermal expansion and resulting deformation of the cross plates and further strain on the cross plates, clips and connection points can be compensated for.

Abstract: A rotary drum comprising a bearing ring loosely arranged on the drum shell and spacer plates arranged between the ring and the shell, a pair of elements for axially holding a spacer plate in position being provided at one end of each spacer plate, one retaining element being arranged on the drum shell and the other retaining element being arranged on the spacer plate. This construction enables the spacer plates to be readily replaced and the radial clearance to be changed without any need to loosen a retaining element fixed on the drum shell.

Abstract: The apparatus comprises a main drive including a main motor and main gearing disposed between the main motor and the unit being driven; an auxiliary drive including an auxiliary motor and auxiliary gearing disposed between the auxiliary motor and the main gearing; a clutch between the auxiliary gearing and the main gearing; and a centrifugal brake connected to the auxiliary drive. A further centrifugal brake is connected to the main drive.

Abstract: A plurality of parallel strands comprise chain links which are articulately connected together by grate pins that extend transversely over the entire width of the grate. Rod-like holding members are carried on the chain links and extend substantially parallel to the grate pins. Assemblies of individual support bars have upper edges higher than the chain links, each support bar having two recesses to receive two rod-like holding members. Each assembly of support bars extends substantially between the longitudinal centers of two chain links and is supported by a separate pair of rod-like holding members, for receiving material deposited on the travelling grate chain, and comprises slots for the passage of treatment gas. Each pair of rod-like holding members is interrupted at an intermediate point to provide a gap for insertion and removal of the support bars.

Abstract: A grate chain with a plurality of chain members hingedly joined together by bolts and having lateral edge plates with outwardly directed slide lips by which they are sealingly supported in the traveling grate housing.

Abstract: A housing for a travelling hearth has longitudinally spaced vertical columns which support a plurality of horizontal beams and housing sheets. Some of the beams are subjected to higher temperature loading than are others. Those beams that are subjected to lower temperature loading are fixed to each column whereas those that are subjected to higher temperature loading are fixed only to every second column and are slidably connected to the intermediate columns.
