  • Patent number: 9581112
    Abstract: An air filter and carburetor arrangement includes a round filter and a round filter carrier having a filter plate. The round filter has a central filter axis, which lies at an angle to the filter plate. The carburetor has a carburetor body, in which an intake duct is configured with a duct longitudinal axis, and at one end of the intake duct on the carburetor body a filter connection side for the round filter carrier is configured, wherein the round filter carrier is fixed with at least one surface portion of the filter plate on the connection surface of the carburetor. The design is provided such that the duct longitudinal axis of the intake duct lies in the plane of the filter plate at a lateral distance (r) to the filter axis of the round filter fixed to the round filter carrier.

  • Patent number: 9186847
    Abstract: A method for producing a three-dimensional object by selective solidification of a build material includes irradiating a surface of a mask with at least one radiation source. The mask is disposed at a distance from a build plane and an optical imaging system is used to produce a reproduction of the mask on the build plane.

  • Patent number: 8399167
    Abstract: The present invention relates to a toner composition for forming a masking pattern for use e.g. in connection with a method of building up a three-dimensional body from a large number of mutually connected layers of powder particles that are bonded to each other using radiant heat. The toner composition consists of powder particles that arc able to withstand a temperature of at least 200° C. without sticking together. It also relates to a developer that comprises the toner composition and carrier particles and a method in connection with the production of a volume body by using a toner composition or a developer according to the invention.

  • Publication number: 20130056139
    Abstract: A production of a cast workpiece having increased wear protection in regions, wherein ceramic particles having an average grain size of between 0.2 and 4 mm are mixed with at least one binding agent. Said mixture is applied to a heat-resistant fiber mat at a particular layer thickness, whereby a two-layer structure arises. After hardening of the binding agent, an insert (9) is constructed from the two-layer structure, the shape thereof corresponding to the shape of a surface region of the cast workpiece to be protected. The insert (9) is applied in the casting cavity (8) at the location corresponding to the surface region of the cast workpiece to be protected. The casting cavity (8) is finally filled with casting material, wherein the ceramic particles in the insert (9) are embedded in the casting material.

  • Patent number: 8379869
    Abstract: An acoustic shock protection method and device are provided. A pattern analysis-based approach is taken to an input signal to perform feature extraction. A parameter space is identified, which is corresponding to, the signal space of the input signal. A rule-based decision approach is taken to the parameter space to detect an acoustic shock event. The device may be advantageously implemented using a weighted overlap-add approach to provide low group delay, high-fidelity and a high degree of protection from acoustic shock events.

  • Patent number: 7110554
    Abstract: An adaptive signal processing system for improving a quality of a signal. The system includes an analysis filterbank for transforming a primary information signal in time domain into oversampled sub-band primary signals in frequency domain and an analysis filterbank for transforming a reference signal in time domain into oversampled sub-band reference signals. Sub-band processing circuits process the signals output from the filterbanks to improve a quality of an output signal. A synthesis filterbank can combine the outputs of the sub-band processing circuits to generate the output signal.
