  • Patent number: 5639335
    Abstract: To enhance printed products, lamination is to be carried out by of a controllable pair of laminating rollers, rather than by the conventional method of calender rolling. To do this, the film is applied with relatively low contact-pressure roller pressure in a floating manner. The film can be fed to the laminating rollers without tension by means of a controllable applicator mechanism with a film tension regulating device. The processing rate and sheet length, for example, can be entered by computer so as to control the sequence of the feeder output and also the sequence of a wet cutting device via a suitable incremental-value transmitter from the main drive. Accordingly, processing rates of 60 to 100 meters per minute can easily be set. The quality remains good even at the highest speeds.

  • Patent number: 4831718
    Abstract: Positioning of the individual portions is no longer effected on the laminating station but on a positioning station which is arranged upstream of the laminating station. In the positioning station the individual portions of a layer are deposited and positioned by being pushed against each other. The finally positioned individual layer is then delivered as a closed unit to the laminating station and laminated to form a transformer core. The individual portions are stacked on a stacking station in such a way that they are already arranged in the correct relative position with respect to each other.

  • Patent number: 4559784
    Abstract: A method and apparatus for regulating a bypass flow of a turbocharged internal combustion engine is disclosed. A first preferred embodiment of the apparatus includes an air receiver which is in fluid communication with a turbocharger and an air oscillation pipe. The air oscillation pipe is in fluid communication with an inlet manifold, which inlet manifold is in fluid communication with a bypass duct and the turbocharged engine. The bypass duct is in fluid communication with the turbocharger. Pressure pulsations emanating from the engine propagate into the inlet manifold and the air oscillation pipe causing an air column within the inlet manifold and air oscillation pipe to oscillate. Periodic oscillations of the air column produces periodic pressure differences across the bypass duct, facilitating a bypass flow of air through the bypass duct.

  • Patent number: 4378677
    Abstract: A bypass control apparatus for turbocharged internal-combustion engines, comprising an actuating cylinder for the bypass valve, wherein the pressure of a fluid medium or fluid in the actuating cylinder is controlled by a fixedly adjustable throttle in the fluid supply pipe or line and a throttle in the fluid discharge pipe or line which is adjustable by electromagnetic means in proportion to the engine speed.

  • Patent number: 4346559
    Abstract: A bypass control apparatus for turbocharged internal-combustion engines, comprising an actuating cylinder for the bypass valve of the bypass control apparatus, wherein the pressure of a hydraulic fluid in the actuating cylinder is controlled by a volume flow which is proportional to the engine speed. The hydraulic fluid is returned into a hydraulic tank through a throttle line or pipe containing a fixedly adjustable throttle. The throttle line branches off a hydraulic line or pipe at a location upstream of the actuating cylinder.

  • Patent number: 4328672
    Abstract: A bypass control apparatus for turbocharged internal-combustion engines, comprising an actuating cylinder for a bypass valve of the bypass control apparatus, wherein the pressure of a fluid medium or fluid in the actuating cylinder is controlled by fixed throttles and throttles adjustable by the boost air pressure arranged in the fluid supply and discharge pipes or lines.
