The invention relates to a device for treating the human and / or animal body, for example a core drill, especially an intramedullary reamer for tubular bones, which has a drill head (12). Said drill head (12) is connected to a flexible shaft (14) which is in turn connected by a shank (16) to a drilling machine. The core drill also has a rinsing unit (18) by which means drilled material is removed in the area of the drill head (12). The rinsing unit (18) is connected to a rinsing channel (30) for this purpose, said rinsing channel being configured between the bore and the outside diameter of the flexible shaft (14). The drill head (12) has slits (34) which are connected to an inner cavity (36) of the drill head (12). Said cavity (36) is in turn connected to an inner channel (40) provided in the flexible shaft (14). The rinsing medium is guided into a rinsing head (42) through said inner channel. In the rinsing head (42), the rinsing medium enters a ring-shaped channel (58) through slits (60) provided in the flexible shaft (14). Said ring-shaped channel (58) is connected to a channel (54) to a which a suction device is connected by flexible tubing (56).

A load cell has a longitudinal body including a bending beam axially between a force input element and a force output element, strain gages applied on strainable measuring parts of the bending beam, a hermetically sealed enclosure outside around the strain gages and the strainable measuring parts, and an overload protection arrangement including an overload beam in a recess in the bending beam, a receiving hole partially in the overload beam, and a fitting pin received in the receiving hole so that a defined gap is formed between the fitting pin and an adjacent stop surface in the recess of the bending beam. In further embodiments, the enclosure includes a stiff pipe sleeve and ring elements with flexible membranes connecting the sleeve to the longitudinal body, and a mounting end face of the longitudinal body has centering pins in holes and an 0-ring in a groove.

A rolling-element bearing for bearing rotating components in vacuum devices comprises a plurality of rolling elements (10) arranged between bearing elements (12, 14). A bearing compartment (26) is for example closed by sealing elements (22, 24) on both sides. Said sealing elements (22, 24) have a minor sealing gap (s). The rolling-elements bearing according to the invention are used in vacuum sections in which a pressure of less than 10-3 mbar prevails.

A counterholder (10) for supporting at least a first of two boundary surfaces (12a, 14a), between which a medium (15) is arranged, via which a first compressive force acting on the first boundary surface (12a) and a second compressive force (F2) acting on the second boundary surface (14a) and directed counter to the first compressive force (F1) are exerted, at least temporarily. The counterholder(10) has a shell of elastically deformable design (16) at least in one contact area for positioning at a boundary element (12), which provides the first boundary surface (12a) on a contact side opposite the first boundary surface, and within which, a non-Newtonian, shear-thickening fluid (18) is arranged.

Screw compressor comprising a compressor housing (12) with a screw rotor chamber which is arranged therein, two screw rotors (26, 28) which are arranged in the screw rotor chamber, are mounted such that they can be rotated in each case about a screw rotor axis on the compressor housing (12), and engage into one another by way of the screw contours thereof, and two control slides (52, 54) which arearranged in a slide channel (56) of the compressor housing so as to lie behind one another in a displacement direction which runs parallel to the screw rotor axis, adjoin the two screw rotors with slide compression wall surfaces, and can be moved in the displacement direction, wherein the first control slide (52) and the second control slide (54) can be moved, in a composite position with end sides which face one another, in the displacement direction in a manner which is joint and terminates sealingly with one another, and can be positioned at a spacing from one another in a separated position with the formation of an intermediate space, wherein the control slides form an inflow chamber (198) at least in a transition position which lies between the composite position and the separated position, into which inflow chamber (198) the medium to be compressed flows from one of the compression chambers, by virtue of the fact that it passes between the end sides of the control slides which face one another, and wherein one of the control slides is provided with at least one outflow outlet (212) which adjoins the inflow chamber and through which the medium from the inflow chamber (198) enters into an outflow opening (144) on the slide channel (56), which outflow opening (144) overlaps with the outflow outlet in said transition position.

The assembly to separate tobacco from a compressed tobacco cake has a housing frame (11) with a cutting unit (12) and a rotating cutting plate (13), fitted with a number of cutting blades and rotating around an axis (14). A grinder (21) sharpens the cutting plate with a common counter surface (15). The assembly has at least one sensor (26) near the grinder and / or the counter surface, which registers the sound of the cutting plate in contact with the counter surface as an acoustic body sensor working on the piezo principle, and is linked to the grinder.
