Abstract: Medical techniques include systems and methods for administering a positive pressure ventilation, a positive end expiratory pressure, and a vacuum to a person. Approaches also include treating a person with an intrathoracic pressure regulator so as to modulate or upregulate the autonomic system of the person, and treating a person with a combination of an intrathoracic pressure regulation treatment and an intra-aortic balloon pump treatment.

Abstract: A process for operating a workpiece transport system for a press arrangement includes driving, the system by at least one driving device which can be held in a stoppage position with a braking device. By application of a predefined torque by the driving device, the functioning of the braking device is checked.

Abstract: Aa process for operating a press arrangement involves a press slide and at least one workpiece transport device that are electromechanically driven and electrically supplied by a supply and feedback device having at least one input and at least one output. In the event of a voltage drop at the input of the supply and feedback device, the current intensity at the input of the supply and feedback device is increased.

Abstract: A multistation press, particularly a suction device press, for machining sheet metal parts is provided for the successive machining of workpieces in several stages. Several press stations are arranged behind one another so that workpieces pass through the stations successively. At least one transfer device transports the workpiece. A common driving device for all press stations has a drive shaft divided into shaft sections. At least one press station is assigned to each shaft section. Slides are driven by the drive shaft and are assigned to one press station, respectively. An adjustable coupling is provided between two successively arranged shaft sections for adjusting a specific phase shift between two successive press stations.

Abstract: A transfer device 41 provided particularly for multistation presses 1 has a holding device 46, 47 which is carried by several rods 53, 54, 55; 83, 84, 85 and which can be swivelled in space and positioned by means of the rods 53, 54, 55; 83, 84, 85. The rods 53, 54, 55; 83, 84, 85 are preferably connected with linear driving devices 61, 62, 63; 86, 87, 88 which therefore jointly act upon the holding device 46, 47. In the case of an embodiment having six degrees of positioning freedom, three of the rods 53, 54, 55; 83, 84, 85 are applied to a first hinge point 49 of the holding device 46, 47. By means of their other ends, these rods 83, 84, 85 define a triangle. Of the remaining three rods 53, 54, 55, two 53, 54 are applied to another hinge point 56 and a third 55 is applied to a hinge point 57 situated away therefrom which again defines a triangle together with the other two hinge points 49, 56. In addition to the simple workpiece transfer, such a transfer device 41 permits complicated positioning tasks.

Abstract: A transfer device is provided particularly for multistation presses and is arranged between two working stations. The transfer device has a suction bridge which extends transversely with respect to a transfer direction and which is guided on its ends by two control arm gearings synchronously along a predetermined transfer curve. The control arm gearings are formed by control arms or rods which are connected on the end side with the cross traverse and which, on their respective end situated away from the cross traverse 46, are held in preferably vertically aligned linear axles, in which case the control arms, in respective pairs, enclose the same angle with one another. By the targeted controlling of the linear axles, almost arbitrary transfer curves can be travelled within the scope of the range of the transfer device. All linear axles are directly supported on a stationary frame whereby a high stiffness and precision is achieved even at high accelerations.

Abstract: A device for axially clamping a disc-shaped tool on a flange of a driven spindle with a threaded end, includes a clamping nut, a clamping disc supported on the clamping nut for biasing the disc against the flange and connected with the clamping nut for joint rotation therewith and axial displacement relative thereto, and supporting bodies arranged between the clamping nut and the clamping disc. An actuating member is located between the clamping nut and the clamping disc, and rolling bodies are displaceable along guide paths defined by guide tracks of the supporting bodies and guide track means of the actuating member for radially loading the supporting bodies. An insert member is supported between the clamping nut and the clamping disc and includes a plurality of stops projecting into the guide paths.

Abstract: A sensor for determining the pressure and temperature of the air in a vehicle tire and comprising temperature sensor elements decoupled from the temperature of the wheel rim and coupled to the temperature of the tire air. The temperature sensor elements are arranged on an insulating foil which is stretched over one of the openings of a cover cap which is fastened at the sensor housing so as to be thermally insulated. The temperature sensor elements are connected with connecting leads of the electronic circuit of the sensor via conductor paths of the insulating foil.

Abstract: In a pressure sensor for detecting the air pressure in the interior of tubeless tires of motor vehicles, on a rim having two edge beads extending around its outside and a drum-like base, to facilitate mounting and provide malfunction-free, exact detection of pressure it is provided that the pressure sensor (10) is disposed in a bore (9) of the preferably radially inner section (5) of a bead (3), and in particular the longitudinal axis (43) of the pressure sensor (10) forms an acute angle with the axis (44) of the rim.
