| 20080213520 | Multi-Layer Film With Triple Coextrusion Film - The invention relates to a multi-layer film with a deriving barrier layer and a plastic layer with reduced electrical resistance, whereby the plastic layer with reduced electrical resistance forms the middle layer of coextrusion film formed from three coextruded layers. The barrier layer is connected to the coextrusion film and on the side of the barrier layer facing away from the coextrusion film is provided with a plastic layer of limited extensibility. | 09-04-2008 |
| 20100028637 | Multi-Layer Film Comprising a Barrier Layer and an Antistatic Layer - The invention relates to a multi-layer film comprising a barrier layer, a poorly extensible plastic layer, and an antistatic plastic layer arranged on the side of the barrier layer, opposing the poorly extensible plastic layer. According to the invention, either a layer of material that is generally recognised as safe in terms of food is arranged next to the antistatic plastic layer, opposing the barrier layer, said layer of material being between 5 and 20 μm thick, and the antistatic layer being approximately between 10 and 150 μm thick, or the antistatic plastic layer is embodied as a layer of material that is generally recognised as safe in terms of food, the antistatic plastic layer containing a plastic material that is generally recognised as safe in terms of food and an antistatic agent that is generally recognised as safe in terms of food. | 02-04-2010 |

| 20080218982 | Surge Protector with a Mounting Base - A surge protector includes a housing with connectors for passing through an electrical lead that is to be protected, whereby a surge voltage discharge device is located inside the housing and a mounting base for placement on a mounting rail is located on the outside of the housing. The mounting base on the housing exhibits a power surge proof discharge contact for contacting the mounting rail with the discharge contact being connected to the discharge connector of the surge protector. An attachment is connected in a removeable fashion to the mounting base which includes a contact component which contacts the discharge contact of the mounting base and is connected in an electrically conducting manner with a lead that exits the attachment. | 09-11-2008 |
| 20100328829 | OVERVOLTAGE PROTECTION ELEMENT - An overvoltage protection element with a housing, at least one overvoltage limiting component in the housing, especially a varistor, and two connecting elements for electrically connecting the overvoltage protection element to a current or signal path in a normal state, the connecting elements being in electrically conductive contact with a respective pole of the overvoltage limiting component. In the normal state of the overvoltage protection element, at least one pole is connected to a connecting element via a plug-and-socket connection, and at least one spring is located between the housing and the overvoltage limiting component such that, when the overvoltage limiting component is thermally overloaded, it is turned by the spring separating the at least one pole from the assigned connecting element, and creating a thermally separating connection between the overvoltage limiting component and the housing when the temperature of the overvoltage limiting component exceeds a given boundary temperature. | 12-30-2010 |

| 20100319428 | METHOD FOR HYDROFORMING HOLLOW PROFILE METAL WORKPIECES - A method for hydroforming hollow metal workpieces includes submerging the same in a reservoir of hydraulic fluid. A press is provided having a hydroforming station located within the reservoir and includes a forming cavity configured to receive the fluid filled workpiece and create a fluid cushion spaced between the outside of the workpiece and the inside of the forming cavity. Sealing mandrels supply high-pressure hydraulic fluid to the interior of the workpiece which hydroform the same to the shape of the final part. The outward flow of fluid from the fluid cushion space is controlled, along with the associated pressure, to maintain the fluid cushion at least until such time as the mandrel pushing step concludes, thereby alleviating friction and adhesion between the formed part and the forming cavity. | 12-23-2010 |

| 20110121587 | BUMPER SYSTEM - A bumper system includes a crossbeam having ends constructed to form attachment zones, and two crash boxes which are secured to side rails of a motor vehicle and coupled to the attachment zones, respectively. The crossbeam has a front wall, a rear wall, and an inner wall which extends between the front and rear walls along a major length of the crossbeam. The inner wall is hereby recessed to leave a gap in the area of the attachment zones. | 05-26-2011 |

| 20080304575 | Method for Compression and Expansion of Analogue Signals - In an analog signal compression method with digital compression and digital expansion of linear based or sine-based linear signals, a signal coordination point is determined in a bi-adaptive scaleable mV/step and a time/step structured plane. To accomplish this, the linear or sine-based input signal is digitized, the breaks of the digitized linear or sine-based signal are detected, and the time difference and the amplitude difference of two successive breaks of the linear or sine-based signal are determined. This permits time differences and amplitude differences of successive breaks to be value coded as a data word on the basis of adaptive scaleable time-per-step tables and voltage-per-step tables so that the time-per-step tables and the voltage-per-step tables are selected depending on the absolute value of the determined time difference and amplitude difference, thus producing compressed data. An associated expansion method for reconstructing the original analog signal is also disclosed. | 12-11-2008 |
