A method and device for the production of thermoplastics containing coarse-scale and/or nanoscale, coated, de-agglomerated magnesium hydroxide particles that are supplied to the thermoplastic in the form of a dispersion or suspension in an aqueous or organic solvent, and mixed with the themoplastic. The thermoplastics filled with magnesium hydroxide particles demonstrate improved mechanical properties, particularly an improved modulus of elasticity and low brittleness.

The present invention relates to a throttle for an injection molding machine for injection molding rubber or elastomeric material and comprises a throttle block, an inlet channel and an outlet channel provided therein as well as a throttle means. The inlet channel can be provided at an angle relative to the outlet channel. The throttle means comprises a throttle piston, which serves both to reduce the material flow and inject the rubber or elastomeric materials into the injection mold. A system and method for tempering rubber or elastomeric material in injection molding can be realised with the throttle of the invention, wherein in particular shorter cycle times can be achieved.

Embodiments of the present invention relates to an injection moulding machine or injection unit and to an injection moulding method for injection moulding plastic materials (e.g., elastomeric materials), particularly according, to cold channel and hot channel techniques, comprising an extruder, a first piston/cylinder unit and a second piston/cylinder unit mounted in series thereto. The cylinder of the first piston/cylinder unit leads into the end of the second piston/cylinder unit located at a distance from an injection mould to be filled. According to an aspect of the invention, the elastomeric material is firstly led by means of the first piston/cylinder unit through the cylinder of the second piston/cylinder unit and into the injection mould, wherein the piston of the second piston/cylinder unit frees the flow path to the injection mould. Afterwards, the piston of the second piston/cylinder unit is displaced into the corresponding cylinder in order to introduce the elastomeric material located inside the second cylinder into the injection mould. The piston is retracted once the elastomeric material has been vulcanised on the cold channel nozzles.

摘要:
A deformation device, especially for the steering column of a motor vehicle. The deformation device comprises a deformation tube (2), which can be deformed in a defined manner, as well as a deforming cone (1) associated with the deformation tube (2). The deformation device has at the deforming cone (1) at least one elevation (13, 28) or recess, whose edges (8) engage edges (9) of at least one impression (23, 25) or recess (10), whose shape corresponds to the elevation of the cone or the recess of the cone at the cone-side end of the deformation tube (2), in a positive (material blocking) manner, as a result of which essentially any desired high torque can be transmitted between the deformation tube (2) and the deforming cone (1) without any change in the good behavior in a collision. The design of deformation devices, especially for steering lines of motor vehicles, can be substantially simplified and despite the improvement in product quality that is made possible, considerable cost savings are achieved in the manufacture of steering line components for motor vehicles.

摘要:
An electric power generation system has a multiple jet ejector assembly for recirculating an exhaust stream. The system includes a fuel cell stack having a reactant stream inlet, a reactant stream outlet and at least one fuel cell. A pressurized reactant supply provides a reactant to the multiple jet ejector assembly. The multiple jet ejector assembly includes two motive flow inlets, one suction inlet, fluidly connected to the reactant stream outlet to receive a recirculated flow from the fuel cell stack, and one discharge outlet, fluidly connected to the reactant stream inlet to provide an inlet stream to the fuel cell stack. A pressure regulator is interposed between the pressurized reactant supply and the two motive flow inlets of the multiple jet ejector assembly. A first solenoid valve is interposed between the first motive flow inlet and the regulator. A second solenoid valve is interposed between the second motive flow inlet and the regulator. A by-pass line connects the pressurized reactant supply to the second motive flow inlet. A by-pass solenoid valve is interposed in the bypass line between the pressurized reactant supply and the second motive flow inlet. During low-load operating conditions, the second solenoid valve is open and the first and by-pass solenoid valves are closed, so that pressurized reactant, controlled by the regulator, is directed to the second motive flow inlet. During high-load operating conditions, the second solenoid valve is closed and the first and by-pass solenoid valves are open, so that pressurized reactant, controlled by the regulator, is directed to the first motive flow inlet and pressurized reactant, not controlled by the regulator, is directed to the second motive flow inlet.
摘要:
A conveyor defining a horizontal transport surface receives elongated workpieces in crossed-over and nonparallel orientation at an input side of the surface and moves them in a horizontal transport direction to an output side of the surface. A workpiece-aligning apparatus has a guide extending generally parallel to the workpieces along the surface, a carriage displaceable along the guide parallel to the workpieces, and a pushdown element vertically displaceable on the carriage between a lower position engaging and pushing down the workpieces and an upper position above the workpieces. A drive displaces the carriage along the guide with the element in the lower position and thereby presses the workpieces down against the transport surface and moves the workpieces into generally parallel alignment with one another.
