Title: Automobile safety belt tensioner
Inventor: FOEHL ARTUR
IPC: B60R22/46
Filed: 1992-03-23
Abstract: The tensioner (12) in a seatbelt system for vehicles is equipped with a piston/cylinder linear drive (18) which can be activated by a pyrotechnic gas generator and is swivellably mounted arranged in a support housing (32) between a position of rest and a trigger position. The piston/cylinder linear drive (18) forms a vehicle-sensitive inertia mass which is loaded by spring prestressing in the direction of the position of rest and can be moved into the trigger position by means of inertia forces caused by deceleration. The gas generator is provided with an impact igniter. A spring-loaded impact component is mounted on the support housing (32), said impact component having an anvil for striking on the impact igniter and being held in a stand-by position by being supported on a holding surface of the piston/cylinder linear drive (18). …<IMAGE>…

Title: Fuel cell gas separator
Inventor: YOSHIMURA JOJI
IPC: H01M8/02
Filed: 1999-06-15
Abstract: The present invention is directed to a gas separator for fuel cells obtained as a laminate of unit cells, wherein the gas separator is one constituent of each unit cell, fuel cells using such gas separators, and a method of manufacturing such a gas separator. The gas separator is obtained by press molding a metal plate. The process of forming predetermined rugged shapes in both faces of the gas separator by press molding causes the gas separator to be distorted. The distortion of the gas separator results in a variety of problems.   A gas separator (30) of the present invention has a base plate unit (60) that is obtained by bonding two base plates (62) and (64) molded to have predetermined rugged shapes to each other, filler units (66) that are formed in spaces defined by the two base plates (62) and (64) corresponding to the predetermined rugged shapes of the base plates (62) and (64), and a coat layer(68) that is formed on surface of the base plate unit (60). In the separator (30) of this configuration, distortions occurring in the base plates (62) and (64) molded to have the predetermined rugged shapes are mutually corrected by joining the two base plates (62) and (64) with each other. This arrangement thus effectively prevents a distortion from occurring in the separator (30). An electrically conductive material is interposed between the pair of base plates (62) and (64) to form the filler units (66). This enhances the electrical conductivity and the thermal conductivity of the separator (30). <IMAGE>

Title: Method and device for filling a cavity between two sheets of fire-resisting composite glass
Inventor: LINDBERG ANDERS
IPC: C03C27/12
Filed: 2002-09-19
Abstract: A fire-resisting composite glass is comprised of at least two glass plates ( 1, 2 ) and an interspaced cavity ( 6 ). The distance between the glass plates ( 1, 2 ) is determined by an encompassing bead ( 3 ) of plastic spacer material. In addition, in the margin region between the glass plates ( 1, 2 ) a bead ( 4 ) of sealing material is introduced. With the aid of at least one core element an opening is formed in the bead ( 3 ) of spacer material for filling the cavity ( 6 ). After the filling, this opening is closed with an entrainer stopper and simultaneously the cavity ( 6 ) is vented. During the closing the plastic spacer material ( 3 ) is joined again in the region of the opening and subsequently the entrainer stopper is covered with sealing material ( 4 ). The method and the device for carrying out the method permits the automatic application of encompassing beads ( 3, 4 ) of spacer material or of sealing material as well as the sealing and protection of the margin regions before the cavity ( 6 ) is filled.
