Abstract: A plastification and injection unit in injection-molding machines for processing of polymer materials, for example rubber, has a plastification screw that is disposed so as to rotate in a screw cylinder, which simultaneously represents the injection piston. The screw cylinder is disposed in an injection cylinder, in an axially displaceable manner. The injection cylinder can be connected with the sprue channel of an injection-molding die by way of a nozzle, and the injection piston has a back-flow barrier. The screw is axially displaceable in the screw cylinder by means of a separate drive. The screw tip projects out of the screw cylinder and has a closure body having a sealing surface for contact with the face surface of the screw cylinder.

Abstract: A method continuously creates a bainite structure in a carbon steel, especially a strip steel by austenitizing the carbon steel; introducing the austenitized carbon steel into a bath containing a quenching agent; adjusting the carbon steel to the transformation temperature for bainite and maintaining the transformation temperature for a certain period of time; and then cooling the carbon steel. The carbon steel stays in the bath until a defined percentage of the bainite structure relative to the total structure of the carbon steel has formed. Residues of the quenching agent are removed from the surface of the carbon steel by blowing the same off when the carbon steel is discharged from the bath, and the remaining structure components of the carbon steel are then transformed into bainite in an isothermal tempering station without deflecting the carbon steel at all.

Abstract: A solution is supposed to be created with a method for generating positively and/or negatively ionized gas analytes for gas analysis in an ion mobility spectrometer or in a mass spectrometer, with which method the gas analyte can be ionized without the restrictions of previous ionization methods for gas analysis in an ion mobility spectrometer or in a mass spectrometer, forming positive and/or negative ions. This is achieved in that the positive and/or negative gas ions are generated by means of a plasma, which is brought about by means of a dielectrically inhibited discharge, whereby the dielectrically inhibited discharge is produced in that a noble gas is passed in through a capillary made of a dielectric material, whereby an alternating voltage is applied by means of two electrically insulated electrodes disposed on the capillary adjacent to the exit region of the capillary, and the gas analyte is passed to the exit region outside of the capillary.

Abstract: A tunable diode laser system with external resonator in Littrow or Littman configuration has an optical lattice on which the light beam from a laser diode is diffracted, a support element to hold the lattice or to hold a mirror, which reflects the light diffracted by the lattice, and an actuator to change the position of the lattice or the mirror. The tunable diode laser system enables a reliable mode-hop-free tuning and furthermore is easy and economical to realize by having the support element include a carrier, on which the lattice or the mirror is arranged, and a base body, while the actuator acts on the carrier and rests against the base body. The carrier is connected to the base body via linkages, such that a linear deflection of the actuator is transformed into a rotation of the carrier in the plane of the light beam, while the center of rotation lies outside the base body.
