20080226876 | Method for Producing a Core Material Reinforcement for Sandwich Structures and Said Sanwich Structures - A sandwich structure reinforcement carried out by a gripper, which pierces the sandwich structure or the core material, only at one side, thereby obtaining a hole penetrating through, e.g., a polymer rigid foam. At the opposite side, the gripper catches the reinforcing structure (for example a sewing thread, pultruded fiber-plastic composite rods) and inserts the reinforcing structure into the sandwich structure during back movement thereof. The through hole is additionally enlargeable by the reinforcing structure, thereby making it possible to obtain an important fiber volume part in the through hole of the core material. | 09-18-2008 |
20100263504 | DEVICE AND METHOD FOR PRODUCING A REINFORCED FOAM MATERIAL - The invention relates to a device for producing a reinforced foam material and for receiving a textile semifinished product in a hook. To this end, the device has a first subunit having a transport device and a second subunit having a receiving device. The transport device is designed to convey the textile semifinished product into the receiving device, and the first subunit and the second subunit are designed such that the textile semifinished product can be presented in defined length by a relative movement of the first subunit relative to the second subunit. Furthermore, the receiving device of the second subunit is set up such that the textile semifinished product can be placed in the hooks by a relative movement of the receiving device relative to the hook. | 10-21-2010 |

20140134422 | IN-MOULD-FOAMING PROCESS USING A FOAMABLE MEDIUM WITH OUTER LAYERS, AND PLASTICS MOULDING OBTAINABLE THEREFROM - The use of a solid, foamable plastic, for example poly(meth)acrylimide (PMI), polyvinyl chloride (PVC), polyurethane (PU) or poly(meth)acrylate (PMMA), permits the production of a plastics foam composite moulding which is in essence homogeneous and which, in the course of the foaming process at about 200 degrees Celsius, forms a stable mechanical bond with an outer layer or a plurality of outer layers or with a plurality of identical or different outer layers. | 05-15-2014 |

20120239230 | CONTROL DEVICE AND METHOD FOR THE OPERATION THEREOF - A control apparatus has a control lever, in particular for controlling a locomotive or a traction vehicle, and a sensor device for detecting an operating position of the control lever. The sensor device has an angle measurement device which is suitable for measuring an adjustment angle of the control lever, forming a digitalized angle value. A measurement range of the angle measurement device is greater than an adjustment angle range of the control lever and an evaluation device is connected to the angle measurement device which determines the operating position of the control lever based on the digitalized angle value of the angle measurement apparatus. | 09-20-2012 |
