Abstract: A device for handling pot-shaped hollow bodies, more particularly transport containers for semiconductor wafers or for EUV lithography masks includes a wall, which encloses an inner space, a gripping and moving apparatus arranged in an inner space for moving the hollow body within the inner space and a wall opening which is formed by the wall, can be closed by a closure body and through which the inner space is accessible. The device includes a lid handling unit which can be detachably connected to the lid. The lid can be connected to the lid handling unit and is separated from the hollow body.

Abstract: An apparatus for cleaning pot-shaped hollow bodies, in particular transport containers for semiconductor wafers or for EUV lithography masks includes a support wall onto which the hollow body can be placed by way of its edge surface, a locking device by means of which the hollow body can be sealingly and releasably connected to the support wall, a passage opening which is formed by the support wall and is arranged radially within the locking device, a cleaning device by means of which a first cleaning fluid can by dispensed for cleaning the hollow body inner surface when the hollow body is connected to the support wall and a first discharge channel with a first end. The first discharge channel is in fluidic communication with the passage opening and with which the first cleaning fluid dispensed by the cleaning device can be discharged.

Abstract: The invention relates to transporting rollers (22) for transporting essentially flat articles, to holding-down means (23) for pressing the articles onto transporting rollers (22), and to a transporting system (30). In this case, the transporting roller (22) is of at least two-part configuration and comprises a spindle element and at least one track element (1), the latter enclosing the spindle element in a tubular manner.

Abstract: A device for galvanizing of member-shaped substrates includes a base (1), an adapter (5) supported on the base (1) for supporting a to-be galvanized member-shaped substrate (2), an upper sealing ring for securing the to-be-galvanized member-shaped substrate to the adapter (5), an annular complementary member (10) located opposite the upper sealing ring (3) and having counter-recesses complementary to a recess formed in the lower end of the sealing ring (3) and in which a respective O-ring (7) is received, with the annular complementary member (10) being mounted in the base (1) without any side clearance and sealing, together with the sealing ring (3), with the respective upper and lower O-rings (6, 7) being received in respective recess, an electrolyte region.

Abstract: A connecting plug for connecting an input/output unit to a machine control with a central bus, wherein the input/output unit is to be connected to a multi-strand electrical cable connected to a bus node, has a housing with a first plug connection for an incoming cable and a second plug connection for an outgoing cable. The incoming cable is looped through to the outgoing cable forming a looped-through cable. The housing has a connector for the input/output unit. An electronic device is arranged in the housing and connected to the connector. The connector is connected by the electronic device to the looped-through cable.

Abstract: A contact clip for an insulated, multi-strand electric cable has first and second clip parts engaging one another. The first clip part has a receptacle for correctly positioning the cable and the second clip part has contact pins assigned to a strand of the cable, respectively. The contact pins pierce the cable insulation and electrically contact the strands of the cable. They are positioned transversely to a longitudinal cable direction adjacent to and at a spacing from one another. This spacing matches the strand spacing. The receptacle is wider than the cable in the transverse cable direction. A fitting member is inserted into the receptacle for determining a lateral position of the cable in the receptacle. A first contact pin, depending on the lateral position of the cable within the receptacle, either engages one of the strands of the cable or the fitting member.

Abstract: A circuit for filtering pulse sequences of a given frequency out of a composite signal includes a series combination of a monostable multivibrator (MF) and a random-access memory (RAM), an address register and a clock. The monostable multivibrator (MF) serves as a pulse shaper of incoming signals. The input (D.sub.E) and output (D.sub.A) of the random-access memory (RAM) are connected to the inputs of an AND gate (UG). An address counter register (AR) associated with the random-access memory (RAM) has a count cycle whose duration is equal to the pulse spacing of the sequence to be recognized. During each clock period (T2), the current signal state of the input (D.sub.E) of the random-access memory (RAM) and the content of the addressed memory cell are checked for equality by the AND gate (UG) and the current signal state is then written into the cell.
