Abstract:
The invention is directed to a penumatic or hydraulic drive for opening and closing of doors, in which the linear motion of a double-acting piston 5 driven by a pressure medium is converted into a rotary motion of a spindle 2 through a piston rod 6 and a helical gear box 3. Herein a blocking lever 10 supported in a stationary manner is provided, which in the closed position of the door engages under the action of a spring 18 at a part 11 connected with a piston 5, wherein said blocking lever secures the piston in its end position and is held in its open position counter to the force of an additional spring 15 by a power cylinder 14 acted upon by the pressure means.
Abstract:
A method for the operation of a plasma device (100) is described in which particles (2) are arranged in a plasma, wherein a generation of electric travelling waves (1) is provided, under whose effective action the particles (2) in the plasma device (100) perform a directed movement to at least one pre-determined collection area (20, 20A). A plasma device for carrying out the method is also described.
Abstract:
A conductor track carrier is intended to contact-connect electrical components. The carrier has a flexible base film, a conductor track on the base film, and a contact-connection eye arranged in a contact-connection section of the conductor track carrier and electrically coupled to the conductor track. The conductor track carrier has a respective recess on two opposite sides of the contact-connection section, and web elements formed between the recesses in such a manner that the contact-connection section is pivotably mounted.
Abstract:
Rotary drive, particularly for vehicle doors, in which the piston motion of a piston-power cylinder-unit 5 is converted into a rotary motion by means of roller pairs 14 which engage into oblique slots 10, 11. The oblique slots are provided in cylinders 4, 6 arranged coaxially inside each other and one of the cylinders is connected to the power output shaft 7. The slots exhibit an axial direction at their ends. Herein the cover 2 of a pot-shaped housing 1, through which cover the power output shaft 7 passes, exhibits a collar 15 projecting outwards and embracing the power output shaft. The power output shaft 7 is provided with a cup-type seal 17 seated firmly upon it, whose surface contour 18 overlaps outwardly the collar 15 and which with its edge 19 rests tightly at the cover 2. The cover is provided with an axially oriented groove 20 on its side facing away from the collar, into which groove the edge of the pot-shaped housing 1 is tightly fitted.
Abstract:
We have developed a reduced Drosophila heart preparation in which dissection of the fly heart removes nervous system input and reveals its inherent myogenic activity, which can be preserved for several hours. High speed image capture combined with computer-based analytical packages allows us to generate the equivalent of M-mode traces obtained from ultrasounds of human hearts.
Abstract:
A conductor carrier includes a base insulating film, a contact insulating film, at least one first printed conductor and one second printed conductor. The contact insulating film includes at least one first recess and one second recess. The printed conductors are embedded between the two insulating films and each forms a first overlapping region with the first or second recess of the contact insulating film. The conductor carrier also includes an insulating region which separates the first printed conductor from the second printed conductor in an insulating manner due to the contact insulating film being less raised than outside the insulating region, and extends between the first and second recesses of the contact insulating film in a meandering manner. A configuration having the conductor carrier is also provided.

Abstract:
A one-leaf or two-leaf sliding door, swinging/sliding door or pocket door, particularly for vehicles, has an electric, pneumatic or hydraulic drive. A nut is attached to the at least one door leaf and a spindle extends through the nut. A drive for moving the at least one door leaf is provided either to rotate the spindle directly or to linearly move the at least one door leaf. A freewheel is mounted on an end of the spindle, wherein the freewheel has a component which is stationary relative to but capable of rotating together with the spindle. A releasable brake or clutch is provided for preventing rotation of the freewheel component.
Abstract:
The invention relates to a cable for bringing into contact with a contact point of a flexible strip conductor, to a contact strip for one or more cables of this type, and to a system for bringing control electronics, which are situated on a flexible printed circuit board, into contact with at least one electrical and/or electronic component. The component is, particularly, a mechatronic transmission or engine controller of a motor vehicle. A special contact with a welding boss is placed at the end of a cable. A bundle of cables of this type is fixed in a defined position by way of a contact strip. The invention enables, for the first time, one or more cables to be directly brought into contact with the contact point(s) of a flexible strip conductor. This advantageously eliminates additional contact points and parts such as mating connectors, etc. whereby leading to a distinct improvement in quality and reduction in costs. The invention is particularly suited for use in contacting systems in mechatronic transmission or engine controllers, etc. of a motor vehicle.
Abstract:
A method and a control apparatus for controlling the movement of a sliding door in its end closing area by always permitting movement of the door leaf in a closing direction by providing a free wheel, only permitting movement of the door leaf in an opening direction when a brake, coupling or other fixation for a fixed part of the free wheel remote from the door leaf is disengaged, determining door position, deactivating any present safety devices against pinching in the predetermined end closing area, reducing a current supply of the door drive and thus a closing force acting on the door leaf to a lower value as long as the door leaf is within the end closing area, and disengaging the brake, coupling or other fixation which acts on the part of the free wheel remote from the door leaf.
