A breakaway coupling for connecting two fluid lines, comprising a first coupling part () which can be connected to the first fluid line and a second coupling part () which can be connected to the second fluid line. The coupling parts () can be disconnected from one another by way of a defined disconnecting force, wherein at least one of the coupling parts () has an outflow prevention valve () with a valve seat () and with a sealing body () which is configured for interaction with the valve seat (). The outflow prevention valve () has a hold-open element () which is configured to enable a passage of the fluid in the joined-together state of the coupling parts (). The outflow prevention valve () is configured to prevent an outflow of the fluid from at least one of the fluid lines in the disconnected state of the coupling parts (). The breakaway coupling has an anti-rotation safeguard which, during operation of the coupling, prevents a rotation of the first coupling part () and the second coupling part () with respect to one another. According to the invention, the valve seat () has a bearing surface () for the sealing body (), wherein a compensatory element () is arranged in the region of the bearing surface (), which compensatory element () consists of a material which has a lower hardness than the material of the valve seat () and/or than the material of the sealing body ().

The invention relates to a nozzle () for dispensing a fluid, comprising a manually operated control lever (), which can be moved between a closed position and an open position in order to control the dispensing of the fluid. According to the invention, the control lever () comprises a latching pawl (), which is designed to engage in a slotted guide () of the nozzle (), the latching pawl () being designed to follow an opening movement of the control lever () in an opening direction () and a closing movement of the control lever () in a closing direction (), the latching pawl () being able to be moved, by cooperation with the slotted guide (), relative to the control lever () in a direction perpendicular to the opening and closing direction () into a catch position (), in which the latching pawl () fixes the control lever () in the open position. Because of the interaction of the latching pawl () and the slotted guide (), a locking device that is easy for the user to operate is created for the control lever by means of a simple design.

The invention relates to a biomaterial and/or a biocomposite based on sunflower seed shells/husks. According to the invention, it is proposed that sunflower seed shells/husks are used instead of wood, bamboo or other wood-like fiber products as the original material for the biocomposite products and are used for the production of such products in order to improve the previous biomaterials, and in particular also to design said materials for improved cost efficiency and to improve their material properties.

Biocomposite and/or biomaterial with sunflower seed shells/husks

A process for producing a biomaterial product based on sunflower seed hulls/sunflower seed husks comprising providing or producing a sunflower plastic compound (SPC) compounded material (SPC PBS, SPC PBSA), wherein the material is obtained by compounding a sunflower seed hull material/sunflower seed husk material with a biodegradable plastic, for example polybutylene succinate (PBS), polybutylene succinate-adipate (PBSA), or the like. The SPC compounded material is preferably used for producing an injection molded product, for example biodegradable containers, packagings, films or the like, in particular coffee capsules, tea capsules, urns, cups, plant pots, flowerpots, or the like.

The invention relates to a filling nozzle for dispensing a liquid into a tank of a motor vehicle, having a main valve (). It is provided according to the invention that a safety valve () is arranged downstream of the main valve (), which safety valve can be moved from a closed position into an open position by means of an opening movement directed in an upstream direction, and that a safety device () is provided which has an operative connection to the safety valve () and which is designed to detect the insertion of the filling nozzle into a tank provided for the corresponding liquid and which effects a movement of the safety valve from the closed position into the open position when an insertion of the filling nozzle into a tank provided for the corresponding liquid is detected.

Filling nozzle

A fuel pump nozzle for delivering fuel, with a manually operated switch lever which is movable between a closed position, in which there is no delivery of fuel, and an open position, in which fuel is delivered, wherein the switch lever is biased by a restoring spring in the direction of the closed position and automatically returns to the closed position when the manual force applied declines, wherein the pump nozzle is provided with a hold-open aid which reduces the force required to hold the switch lever in a particular open position compared to the forces required to hold the switch lever open in other open positions.

Tubular film die head for extruding single-layer or multi-layer film which has at least the following features: a substantially annular die gap, fastening elements which fix at least two components with respect to one another which together border areas bearing plastic melt within the tubular film die head, coolant-carrying elements. At least one part of the fastening elements is structured as coolant-carrying elements.

Blowing head for extruding films, comprising clamping elements containing ducts for cooling air

A tubular film blowing head is provided with one outer and one inner nozzle ring between which a ring chamber is formed extending in a conical or parabolic manner towards the circular nozzle gap and of which the inner nozzle ring, which is provided with a central bore for exchanging the pressurized air, is connected by means of a screw connection to a central cone piece of the blowing head. This central cone piece has a bore that is aligned to the central bore. In order to create a screw connection between the inner nozzle ring and the center cone piece that is firm and simple to produce, the inner nozzle ring is connected to the central cone piece by means of a threaded bolt penetrating the central bore of the nozzle ring and provided with an axial bore in that the threaded bolt is screwed into the bore of the cone piece, which is embodied as a threaded bore.

Tubular film blowing head

An extruder die head, preferably a blown film head, comprises an internal cylindrical mandrel and a jacket, which envelops concentrically said mandrel. Between said mandrel and jacket an annular channel is formed that empties into a die slit. The invention also comprises at least one line, which empties into the annular channel in the area opposite the die slit and which feeds a melt. To prevent a slit between the central mandrel and the jacket, enclosing said mandrel, where the polymer melt could accumulate and deposit, the mandrel is made as one piece with a flange-shaped foot. The jacket rests with its bottom face sealingly on the annular surface of the flange-shaped foot and is connected, for example fastened, to the same. The annular channel extends from the peripheral surface of the mandrel to the flange-shaped foot up to and into the transition region. The line, feeding in a melt, empties into this transition region.
