Abstract: Disclosed is a coupling for machine tools, comprising a first main coupling part (1) and at least one additional main coupling part (2) for mechanically fastening an attachment (4) to the machine tool. A first power coupling part (5) is provided on the first main coupling part (1) and at least one other power coupling part (6) is provided on the additional main coupling part (2) in order to supply power to the attachment (4) or the machine tool. Furthermore, an actuator (7) which is used for actuating a locking mechanism (8) that interlocks the two main coupling parts (1, 2) is disposed on one of the main coupling parts (1, 2). A connecting device (9) is provided for automatically connecting the power coupling parts (5, 6). Said connecting device (9) for the power coupling parts (5, 6) is fitted with at least one spline (20) which can be preferably moved in a linear manner and slides the power coupling parts (5, 6) onto one another for connecting purposes by means of a wedging surface (21).

Abstract: The present invention relates to a power source coupling for connecting two power coupling parts (5, 6): a first power coupling part (5) which is mounted on a first component (1) so as to be longitudinally displaceable and has a first connecting plate (16) with one or more first power coupling elements (18), and a second power coupling part (6) which is mounted on a second component (4) so as to be displaceably mounted between a first and a second position. The second power coupling part (6) has a second connecting plate (17) with one or more second power coupling elements (19) which are able to cooperate with the first power coupling elements (18) when the first power coupling part (5) is in the first position.

Abstract: The invention relates to an electrosurgical instrument (5) for an endoscope or a catheter, which can be operated by means of a high-frequency current, contact electrosurgical treatment and non-contact plasma coagulation in an ionisable gas. A stationary electrode (33) is arranged on the distal end of a guiding tube (7) that can be introduced into the instrument channel (1) of an endoscope catheter (3), and when the electrosurgical electrode for the contact treatment is in the retracted position in the guiding tube (7), the stationary electrode is connected to the electrosurgical electrode (11) by means of a contact element (37).The retracted position of the electrode (11) can, but not necessarily, be maintained by an abutment (21) of a handling device (13) and/or by a suitable arrangement and measurement of the contact element (37). The retracted position of the electrode (11) does not need to be optically controlled.

Abstract: Surgical instrument which has a main part (10) with a shaft (12) and a fixed handle part (14), on which a moveable handle part (20) is supported pivotably. The pivotable handle part (20) engages through a slit (18) of the main part (10) and is linked to a slider (16). The slider (16) is guided axially shifted on the shaft (12) so that it cannot be removed. At the proximal end of the work stroke the slider (16) can be removed from the guide and shaft. Spring tongue (50) arranged on the pivotable handle part (20) comes against the main part (10) when the handle parts (14, 20) are spread apart and prevents the slider (16) from entering the cleaning position in which it is released from the shaft (12). The spring tongue (50) can be pressed against the moveable handle part (20) in order to enter the slit (18) of the main part and to release the locking.

Abstract: The combustion system for implementing the process has a combustion grate, hoppers below the combustion grate for supplying primary combustion gas through the grate and nozzles that lead into the furnace above the combustion grate to supply secondary combustion gas. At least one extraction duct for flue gas is provided at the rear end of the furnace above the combustion grate. This duct is connected to the suction side of a fan. The pressure side is connected to nozzles arranged in the upper area of the flue gas pass. The nozzle height allows the flue gases a residence time of at least 1 second after secondary gas is supplied.

Abstract: A multicoupling device for lines, especially hydraulic lines, wherein first and second coupling parts (7, 8) are provided with a plug (5) or a collar (6) for coupling units (1, 2) whose number corresponds to the number of connections to be produced. The coupling units (1, 2) are embodied in the form of a self-locking, snap coupling with a locking collar (9) which can be displaced in relation to the socket (6). The two coupling parts (7, 8) can be brought together via an operating element (10) and can be pressed apart and are mutually lockable in the coupling position. The locking collars (9) interact with a common switch plate (11). The operating element (10) is rotatably mounted on an axis (12) on the switch plate (11). The switch plate (11) can be adjusted in relation to one of the two coupling parts (7, 8) in the direction of closure or opening of the coupling units (1, 2).

Abstract: An arrangement for fixing an add-on piece (1), e.g., an excavator shovel, to a shovel boom (2) or to a vehicle in a replaceable manner is provided. Two parallel holding bolts (3, 4) are arranged on the add-on piece (1) and can be gripped by grippers (6, 7) that can be displaced in relation to one another and which are arranged on a holding element (5) on the shovel boom. The grippers (6, 7) include at least partially open insertion openings (8, 9) for the holding bolts (3, 4). One gripper (6) is connected to the holding element in a fixed manner and the other (7) is held in a guide of the holding element in a linearly displaceable manner. Spring elements (11) acting in a closing direction of the gripper (7) are associated with the linearly displaceable gripper (7).

Abstract: A grate furnace with a grate includes grate steps made of grate elements lying next to one another. Every second grate step in the longitudinal direction of the grate can be driven for carrying out stoking movements and the grate steps in each case lying therebetween are stationary. Drive devices for driving the moveable grates are arranged in housing chambers and are in this way protected against impairment caused by material falling through the grate. A certain section of the housing chamber is open toward the bottom so that it is accessible even during operation of the grate furnace.

Abstract: A grate furnace with a grate (4) consisting of grate steps (15, 16, 17) composed [lacuna] grate elements lying next to one another, of which grate steps in each case every second grate step (15, 17) in the longitudinal direction of the grate can be driven for carrying out stoking movements and the grate steps (17) in each case lying therebetween can be fixed, has drive devices (18) under the grate, which are in each case arranged in housing chambers (25) and are in this way protected against impairment caused by material falling through the grate. A certain longitudinal section (36) of each of these housing chambers (25) is only partially enclosed and sealed by the under-grate blast chambers (7) and is thus open (37) toward the bottom, so that it is accessible even while the grate furnace is operating.

Abstract: In the process for treating incineration residues from waste incineration plants, the incineration material is incinerated on a furnace grate. The incineration residues produced are quenched in a wet slag remover and conveyed out of the latter. The wet incineration residues which come out of the wet slag remover are firstly divided into two fractions by means of a screening operation, after which the main fraction is washed with water taken from the wet slag remover, and in the process adhering fine pieces are separated off. The washed pieces of the incineration residues are fed for reuse. The washing water together with the ultra fine pieces which have been taken up during the washing operation pass into the wet slag remover. The fine fraction produced during the mechanical separation operation is fed back to the incineration operation.
