The present invention relates to a connecting apparatus for creating a connection to a measuring instrument or to a valve block/valve with a measuring instrument, and a connection to a pipeline or to a metering orifice device installed in a pipeline. The connecting apparatus comprises: a first connecting device that provides a direct or indirect sealing connection to the pipeline or to the metering orifice device with a first recess extending through in the longitudinal direction, and a second connecting device that provides a direct or indirect sealing connection to the measuring instrument or to the valve block/valve with a second recess extending through in the longitudinal direction. The first and second connecting devices are interconnected with sealing effect. The connecting unit is designed so that the sealing connection can be created solely by rotation of the connecting unit without rotating the first and second connecting devices.

A humidifier including a housing which is used to receive a humidifier module. The housing can be connected by the housing cover and is provided with at least one first sealing element, which seals the humidifier module in relation to the housing. The humidifier module is arranged in an axially displaceable manner on the first sealing element.

A torque transmission device is provided with an outer tube having a non-circular internal circumference and an inner tube having a non-circular external circumference inserted into the outer tube. The two tubes have a predefined rotational clearance as the result of a gap formed between the internal and the external circumference. At least one elastic wire cushion-like element is provided in the gap between the two tubes. The two tubes are displaceable in relation to one another, in the longitudinal direction of the tube, in such a way as to make possible length compensation, even under load.

A method for approaching a predeterminable end point of a seam spaced from the edge of a workpiece, with a sewing machine which comprises an adjustable needle and lower transport, a sensor arranged before the needle and triggering the process for the positioning of the needle in the end point during passage through the edge, a pulse generator coupled with the main shaft of the sewing machine for the delivery of counting pulses for a pulse counter, and a micro-computer which controls the action of the feed means as a function of the pulses originating from the sensor and from the pulse generator. To execute a desired shortening of the length of one or more of the last stitches before the end point of a seam, the workpiece is moved back by the difference between the desired stitch length and the stitch length set by the setting device, before execution of the adjusted feed. For correction of the stitch length executed during the feed phase, the cloth feeder is connected with a switching gear controlled by the micro-computer for controlled switching on during its reversed feed phase which precedes the respective forward feed phase.

Automatic sliding apparatus is provided for automatically stamping stator and rotor laminations for electric motors from workpiece blanks. To accommodate utilization of a plurality of sets of tool dies on a single driveable press ram, a tool changing device is provided which includes a tool holder guide track for movably guiding the tool holder along a straight guide path in a plane at a tangent to the workpieces to be machined. With the plurality of tool die sets mounted at the linearly guided tool holder, tool exchanges can be effected simply and automatically, utilizing a linear drive mechanism for moving the respective tool die sets along the frame of the tool holder.
摘要:
A circuit or control arrangement for an adjusting drive of a press ram of a high-speed cutting press which includes top and bottom dies respectively attached to the press ram and a platen of the press with the top die being adapted to dip or penetrate during a cutting process into the bottom die. An arrangement is provided for maintaining the depth of penetration of the upper die means into the lower die means at a constant value in dependence upon an operating condition of the high-speed cutting press. The maintaining arrangement may include at least one limit switch operatively connected with an oscillator stage which provides adjusting signals to the drive motor. In lieu of a limit switch, a cutting force measuring sensor member may be interconnected with an evaluator circuit and the oscillator means so as to control the drive motor.

In loading a press, it is desirable to provide a loading device which can be driven independently of the main driving means of the press and which causes a minimum of surface damage to the blanks being loaded into the press. To achieve this, gripper elements are provided which are coupled to adjustable drive systems controlled by a numerical control unit. The gripper elements are capable of motion in at least two planes perpendicular to each other to remove devices from the stack and carry them along a preselected path into a tool chamber of the press.
