  • Patent number: 5290505
    Abstract: A method is indicated of recycling plastic sheet material coated with adhesive and available in chopped form. The method provides for separating the plastic from the adhesive. In a first method step the chopped sheet material (4) is introduced into a solvent bath (1) where the chopped sheet material (4) is moved for a predetermined dispersing time under mechanical action. The mechanical action preferably is exercized by rolling or kneading. In a second method step, the adhesive dispersed in the solvent is separated from the chopped sheet material (4) by mechanical action of forces--preferably by introducing squeezing forces in a conveyor screw.

  • Patent number: 5235896
    Abstract: In a position independent locking of a hydraulic cylinder/piston mechanism, a pressure limiting member is provided in the supply pipe for the hydraulic medium, with the pressure limiting member being open during the hydraulic displacement of the piston and is closed during lack of hydraulic pressure. The pressure limiting member opens starting from a specific pressurization of the hydraulic medium as a result of a force generated by means of the piston and is located in a related working chamber.

  • Patent number: 5213024
    Abstract: A damping mechanism for decelerating the movement of a piston of a cylinder/piston mechanism includes at least one elastically deformable damping element, which in the installed state is disposed undetachably between two holding regions which are spaced apart in the direction of the piston movement and wherein one holding region communicates with the cylinder and the other holding region communicates with the piston during deceleration.

  • Patent number: 5188051
    Abstract: The power steering mechanism for vehicles, in particular motor boats, has a control wheel that is drive-connected to a control via cable that is attached thereto and a lever system connected thereto. The core of the cable is mechanically connected to the lever system whereas the sheath of the cable is attached to the displaceable control member of the control valve. The control valve controls a hydraulic operating cylinder whose power piston also acts on the lever system of the control. To simplify and reduce the size of the arrangement, the operating cylinder and the control valve are built directly together in axial direction, and the core of the cable penetrates the control member of the control valve and is connected to the power piston of the operating cylinder and in this manner is also connected to the lever system of the control.

  • Patent number: 4933617
    Abstract: In a servo steering system for motor boats comprising a steering wheel which mechanically acts on the position of a hydraulic control valve, and a rubber cylinder connected to a hydraulic power unit by way of the control valve, the control valve comprises an additional adjustment unit which is connected to an autopilot unit and is controllable by this latter. In this way both normal servo-assisted hand-steering and autopilot steering are made possible in a simple manner.

  • Patent number: 4713371
    Abstract: The present invention relates to the micro-organism Streptomyces purpurascens (DSM 2658), its mutants and variants, a process for the preparation of anthracycline derivatives by fermentation of these cultures and to the anthracycline derivatives themselves. The new compounds are distinguished by antibacterial activity and, in addition, they act against various types of tumors.

  • Patent number: 4594891
    Abstract: A filling level measuring probe detects the filling level in a container by suppression of an oscillator by contact with a filling material. The oscillator consists of a hollow body 16, which can be connected through a shaft 14 and a screw-in part 12 with a container wall 10 and is set in oscillation with oscillations in the radial direction over a crosspiece 20 mounted in hollow body 16 by means of an electromechanical transducer 26 which is mounted on crosspiece 20. The oscillations are converted by a second electromechanical transducer 28 into an electric signal, of which the amplitude is changed with suppression of the oscillations as a result of contact of the hollow body 16 with the filling material.

  • Patent number: 4580903
    Abstract: An automatic dough parting and kneading machine has at least one channel between the parting chamber and the kneading apparatus. Means are provided to periodically and selectively raise the kneading apparatus into at least partial telescopic engagement with the channel. Thereafter, the kneading belt (on which the pieces of dough are carried) is periodically advanced.
