Abstract: The invention relates to a rubber sprung railway wheel with a respective annular groove formed by lateral shoulders 4-7 on the wheel tyre 1 and the wheel rim 2 and several spaced, prestressed rubber elements 3 embedded in the annular chamber defined by the annular grooves. In order to limit the axial mobility, mutually overlapping radial projections 6, 8 are provided on one side of the wheel in the area of the shoulders 4, 6 leaving an annular gap. Located in the annular gap between these radial projections 6, 8 is an axially prestressed rubber element 9, whose axial prestress is balanced by the axial shear stress in the rubber elements 3 embedded under prestress between the wheel tyre 1 and the wheel rim 2. Such a railway wheel offers the advantage of improved axial rigidity with exclusively rubber springing. <IMAGE>

Abstract: For testing memory cells (SZ), all the bit lines (BL, BL) are led to a pair of error lines (FLA, FLB). This pair of lines is initially precharged with mutually complementary logic levels. All the memory cells (SZ) of one word line (WL) are always read out in parallel with one another. If "in order", the pair of error lines (FLA, FLB) retains its logic states; in the event of an error, one of the error lines (FLA; FLB) changes its logic state by means of switching transistors (ST). This is detected and evaluated by a comparator circuit (VGL), designed as an XOR or XNOR circuit. A corresponding method is likewise presented.

Abstract: In a control mechanism for a load isolator having a rotating control handle (1) and two control arms (1, 2), it is proposed that the first control arm (1) should be pretensioned by means of spring force and that a latching mechanism (3) be provided, at least one of the control arms (1, 2) latching directly into the latching mechanism (3). The two control arms (1, 2) are each supported rotatably on their one end in the same plane, and engage with one another, such that they can move, at their other end. The latching mechanism (3) in this case consists essentially of a supporting lever (11) having a locking corner (14), and of a roller lever (12), having a pin (13). The end of the first control arm (1) is designed as a tip, so that the pin (13) is clamped in the locking corner (14) in the switched-on state. <IMAGE>

Abstract: An inserted tooth milling cutter with a basic body (10) on whose periphery cassettes (16) for holding one indexable insert (18) each are fastened in recesses (14). Each of the cassettes has at least one slot (22, 40) for the fine adjustment of the position of the indexable insert (18) relative to the basic body (10). The slot runs from one of the side faces of the cassette (16) along an imaginary plane, which runs transversely to the main plane of the indexable insert (18) to be held, into the cassette. Allocated to each slot is a screw (34, 49) which forms a tensile connection with two abutments (32, 48, 50) each engaging in the cassette. The abutments and the screw are arranged on or in the cassette with regard to the slot in such a way that turning of the screw under tension results in a change in the width of the slot, mainly at its free end. The position of the cutting edges (96, 97) of the indexable insert (18) therefore changes due to the deformation of the cassette. <IMAGE>

Abstract: The invention relates to a method for cleaning a valve sealing arrangement under dynamic stress, and an apparatus for carrying out said method, each sealing arrangement sealing two spaces from one another by means of two seals, separated from one another, in a serial arrangement, between or in which spaces there is arranged in a moveable manner a valve part whose jacket surface interacts with the seals and thereby prevents fluids overflowing from one space to the other, an annular space, enclosing the valve part, being provided between the seals, which annular space is bounded on the outside by a housing of the valve and which is connected via at least in each case one connection and one outlet opening to the environment of the valve. The invention ensures, inter alia, that even those critical regions of the slots for the seals which can be accessed only with difficulty are reliably subjected to the cleaning agent. In terms of the method, this is achieved, inter alia, in that the seal which comes into contact with the fluid to be sealed off is supplied with cleaning fluid from the spaces on both sides of the contact surfaces, up to its contact surfaces (provided temporarily at the sealing points) with the valve part on the one hand and the housing on the other hand. The apparatus for carrying out the method is characterised, inter alia, in that each seal (70, 71) is edged in each case on its side facing the space inside the valve housing part (1 or 2) to be sealed by a fluid-permeable boundary wall (41), and in that each of the seals has a limited mobility in the direction of movement of the valve part (4). <IMAGE>
