Patent number: 7498389Abstract: A multi-component kit for a curable composition for fixing purposes, comprising an epoxy component (a), which comprises curable epoxides, and a hardener component (b), which comprises a Mannich base formulation, and the use of Mannich base formulations and, especially, further additives in hardener components for epoxy resins, the Mannich base formulation having specific properties (viscosity, H equivalents, content of free phenol derivatives). The multi-component kits according to the invention can be used within a broad temperature range and enable mortar compositions to be produced which, after curing, exhibit a particularly large tolerance range for temperatures and exhibit particularly high bond stress values at low temperatures and, especially, also at high temperatures.Type: GrantFiled: December 22, 2004Date of Patent: March 3, 2009Assignee: fischerwerke Artur Fischer GmbH & Co.

Publication number: 20040216591Abstract: The invention relates to a discharge device for a cartridge (1) having two chambers (2, 3) that are arranged concentrically to one another and are closed by pistons (9, 10), the discharge device having a discharge ram (11) having a thread (12), which is axially displaceable by being screwed into an end piece which is arranged at the rear end of the cartridge (1) and has an internal thread (14). In order to allow simple manufacture of the discharge device and to facilitate its handling, the discharge ram (11) has an inner plunger (16) which exerts pressure on the piston (9) of the inner chamber (2) and, arranged concentrically with the inner plunger (16), an outer plunger (17) which exerts pressure on the ring-shaped piston (10) of the outer chamber (3), the outer surface of the outer plunger (17) being provided with the thread (12) which extends over its entire length. Furthermore, the end piece having the internal thread (14) is in the form of a threaded ring (13).Type: ApplicationFiled: December 4, 2003Publication date: November 4, 2004Inventors: Amir Assadi, Juergen Gruen, Clements Schmidt

Publication number: 20040168397Abstract: The invention relates to a composite anchor, which consists of an anchor rod (1) anchorable by means of a compound mass in a hole (12) drilled in a building component (13), the anchor rod comprising several cone-like segments (3a, 3b, 3c) widening towards the insertion end (4) and spaced from one another by cylindrical portions (6a, 6b). The length of the cylindrical portions (6a, 6b) is 0.5 times to 2.0 times the length of the cone-like segment (3a, 3b) adjoining the respective portion in the direction of the insertion end (4). This produces a stable mortar shell (14) after the compound mass has hardened, which causes high withdrawal values as a consequence of the cone-like segments (3a, 3b, 3c) settling into the hardened mortar shell (14) following widening of the drilled hole as a result of cracks forming. The composite anchor is therefore especially suitable for anchoring in zones subject to tensile forces.Type: ApplicationFiled: December 4, 2003Publication date: September 2, 2004Inventors: Juergen Gruen, Rainer Jakob, Paul Steurer, Rainer Wohlgethan

Patent number: 6688289Abstract: The fuel injection apparatus has one fuel pump for each cylinder, which has a pump piston, driven by the engine, that defines a pump work chamber, which communicates via a line with a fuel injection valve, disposed on the engine separately from the fuel pump, which valve has an injection valve member, by which at least one injection opening is controlled, and which is movable in the opening direction, counter to a closing force, by the pressure generated in the pump work chamber; a first electrically triggered control valve controls a communication of the line with a relief chamber. A second electrically triggered control valve is also disposed on the fuel injection valve and controls the pressure prevailing in a control pressure chamber of the fuel injection valve, which pressure urges the injection valve member in the closing direction.Type: GrantFiled: February 27, 2002Date of Patent: February 10, 2004Assignee: Robert Bosch GmbHInventors: Nestor Rodriguez-Amaya, Roger Potschin, Juergen Gruen, Ulrich Projahn

Patent number: 6637670Abstract: The fuel injection device has a fuel pump, which has a pump piston that is driven by an engine and delimits a pump working chamber, which is supplied with fuel from a fuel tank and is connected to a fuel injection valve, which has an injection valve member that controls at least one injection opening and can be moved by the pressure generated in the pump working chamber in an opening direction counter to a closing force. A first control valve controls a connection of the pump working chamber to a discharge chamber, and a second control valve controls the pressure prevailing in a control pressure chamber of the fuel injection valve. The connection of the pump working chamber further contains a pressure-holding valve, which maintains a pressure that is higher than the pressure prevailing in the discharge chamber.Type: GrantFiled: May 17, 2002Date of Patent: October 28, 2003Assignee: Robert Bosch GmbHInventors: Nestor Rodriguez-Amaya, Roger Potschin, Jürgen Gruen, Ulrich Projahn

Patent number: 6583259Abstract: The two-component composition for chemical fastenings consists of a first component and a second component separate from the first component. The first component contains a free-radical-curable synthetic resin, which is a mono-acrylate or monomethacrylate of an alkoxylated bisphenol having a viscosity of 100 to 5000 mPa·s at 23° C. The second component is a curing agent for the synthetic resin, such as dibenzoyl peroxide or methyl ethyl ketone peroxide. The first component may also include an accelerator. Good adhesion characteristics in wet concrete are provided by the adhesive composition because a monoacrylate and/or monomethacrylate of an alkoxylated, especially an ethoxylated or propyloxylated, bisphenol is used as the curable synthetic resin.Type: GrantFiled: April 3, 2001Date of Patent: June 24, 2003Assignee: fischerwerke Artur Fischer GmbH & CO.
