Abstract: In a device and method for fixing toner images on a carrier web, rinsing chambers from which a mixture of solvent vapor and air is drawn off are located before and after a fixing chamber. The mixture is passed through a condenser, the discharge of which is re-supplied to the rinsing chambers.

Abstract: A fixing station for a printer or copier includes a heating device for fusing toner to the carrier material and a cover that is selectively insertable between the heating element and the carrier material. The cover may be a window blind type cover. Where two sided fixing is provided, both heating devices have a cover. The cover may have an energy storage spring to cause the heating device to be covered in the event of an emergency. An electro-magnetic locking device may be provided to retain the cover in an open position.

Abstract: A fixing station for fixing toner images on a carrier material is provided in a printer or copier. A flap or shutter mechanism having a plurality of flaps or shutters that are pivotable into an open and into a closed position are arranged between a heat radiation source and the carrier material for controlling fixing of the toner to the carrier material.

Abstract: Continuous process for producing unidirectionally reinforced composite materials by impregnating a continuous reinforcing fiber strand with a thermoplastic matrix in an impregnating bath containing a dispersion of a thermoplastic powder by measuring the width of the strand leaving the impregnating bath and using this measured value for regulating the polymer concentration in the impregnating bath.

Abstract: An electrophotographic printing or copying machine contains as image source a laser diode array (10) having a multiplicity of individually excitable laser diodes (11) which are arranged thereon in a predetermined grid for forming an excitation pattern. Furthermore, a deflection unit (13) deflecting the light beams from the laser diode array (10) and imaging optics which are arranged between laser diode array (10) and photoconductor (17) and are configured in such a way that they image the excitation pattern of the image source optically and free of distortion on the photoconductor (17) as an image point pattern.

Abstract: Image information suitable for positive image generation and present in matrix form is transferred from a data processing device (1) to a converting device (5). The converting device (5) contains a storage device (2) accommodating at least two image lines (m) and an OR logic combining means (3). The latter, in order to generate image information suitable for inverse image generation of a pixel (P), logically combines the image information suitable for positive image generation of this pixel (P) with at least one further such item of image information of an adjacent pixel (P). The generated pixels (P) are output by the converting device (5) to an image reproduction device (4).

Abstract: A process for the continuous production of laminated sheet materials of thermoplastic polymers, reinforcing fibers and metals, in which endless sheets of reinforcing fibers, thermoplastic polymers and metals are combined in layers and the layers thus combined are continuously exposed for 0.1 to 10 minutes to a pressure of 0.5 to 50 bar at a temperature 20.degree. to 150.degree. C. above the melting temperature of the thermoplastic polymer.

Abstract: To produce mouldings for screening against electromagnetic radiation it is highly advantageous to use metal fibre-containing composite materials as obtained by impregnating a bundle of continuous metal filament fibres with a polymeric adhesion-promoting substance, sheathing the resulting compact precursor with a thermoplastic matrix and cutting the resulting extrudate of composite material into defined lengths.The composite materials can be used as such or together with thermoplastic granules.

Abstract: Process for the manufacture of continuous moulded bodies from structures of reinforcing fibres impregnated with thermoplastic plastics, wherein a structure of reinforcing fibres is passed through a melt of the thermoplastic at a pressure of 1 to 800 bar for a length of at least 300 mm and a device for carrying out the process.

Abstract: A lightweight composite material is disclosed which comprises three-dimensionally arranged fibers of at least 50 mm length provided in a thermoplast matrix. The thermoplast matrix is thermally treated to form cavities within the matrix.

Abstract: The continuous process makes it possible to reduce the water content of polymers to minor residual levels (ppm) by adding to a W/O-emulsion an extractant which is subsequently evaporated with the oil.

Abstract: In the illustrated embodiments the undersurface of the thermoplastic coating and the associated electrode are formed with a corrugated structure to produce a correspondingly regularly varying electric field at the exposed thermoplastic surface. The spacing between corrugations is much smaller than the desired x-ray image resolution so that the developed image in effect modulates the regular variation produced by the corrugations. Where the original corrugations are derived from an off-axis zone plate, the developed image can be read out by means of a divergent incident light beam.

Abstract: A process and apparatus for non-mechanically deflecting of a light beam with high resolution characterized by passing a linearly polarized beam through at least one electro-optical deflector and preferably two to obtain four possible beam directions, passing the four beam directions through a multicomponent deflector of prisms which direct each of the four beam directions to a given point on an acousto-optical light deflector which is a two-dimensional acousto-optical light deflector that deflects the beam into two-dimensional arrays on a screen or storage medium, with each one of the four beam directions causing the two-dimensional arrays to be disposed in a different quadrant of the screen or medium. Preferably, the beams leaving the acousto-optic deflector are passed through a four component polarizing filter which prevents undesired overlap between the zero order undeflected portion of the beam and the first orders.
