Publication number: 20240125362Abstract: A pulsation damper for damping pressure medium vibrations in a hydraulic system, has a membrane within a bore of a housing, which membrane is exposed to the pressure medium on its one side and faces a gas-filled cavity inside the housing on its other side, the bore of which is closed by means of a plug. The membrane, in conjunction with the plug and a hollow-cylindrical support body, forms an independently handleable, functionally pre-testable assembly, for which purpose the membrane is substantially cup-shaped, and the support body extends into it.Type: ApplicationFiled: October 12, 2020Publication date: April 18, 2024Applicant: Continental Teves AG & Co.

Publication number: 20210008867Abstract: The invention relates to a method and an apparatus for cold-stamping onto a three-dimensional object. In a first step, an adhesive is applied to the object at a first workstation. In a second step, a transfer film is pressed onto the object by a pressing device at a second workstation. At the same time, the adhesive is cured at the second workstation. As a result, the decorative material of the transfer film adheres to the object at the positions on the object which are provided with adhesive. If, following this, the transfer film is removed from the three-dimensional object after being pressed on, the decorative material remains on the object at the desired positions. At the positions at which in the first step no adhesive has been applied to the object, the decorative material does not adhere to the object but rather remains on the carrier film of the transfer film.Type: ApplicationFiled: September 28, 2020Publication date: January 14, 2021Inventors: Wolfgang ROEDER, Volker SCHMITT, Franz RAUNER

Patent number: 9096762Abstract: The invention relates to a method for the surface treatment of inorganic pigment particles with agglomerates of fine primary particles or single crystals of inorganic compounds, particularly of oxides or sulphates. The method is characterized in that the inorganic compounds are first precipitated from an aqueous solution under suitable pH conditions in a separate vessel in the form of fluffily structured agglomerates and/or single crystals. The precipitation product is subsequently added to an aqueous suspension of inorganic pigment particles.

Patent number: 8641870Abstract: The invention relates to a method for the surface treatment of a titanium dioxide with aluminum phosphate and hydrous aluminum oxide that leads to pigments with improved greying resistance, while simultaneously maintaining good brightness and opacity. The method is characterized in that phosphoric acid is initially added to a TiO2 suspension with a pH value of at least 8, in which context the pH value drops to 3 or below. An alkaline aluminum compound is subsequently added, in which context the pH rises to at least 5, after which an acid aluminum compound is added, as a result of which a pH value of 4.5 to 7 is obtained. The pigment manufactured by the method according to the invention is eminently suitable for use in decorative laminating paper.Type: GrantFiled: March 26, 2012Date of Patent: February 4, 2014Assignee: Kronos International, Inc.Inventors: Volker Jurgens, Janine Siekman, Siegfried Blumel, Alexander Breyder, Volker Schmitt

Patent number: 7979273Abstract: The invention is based on the idea of providing a method for high-resolution, waveform-preserving digitization of analog signals, wherein conventional scalar logarithmic quantization is transferred to multi-dimensional spherical coordinates, and the advantages resulting from this, e.g., a constant signal/noise ratio over an extremely high dynamic range with very low loss with respect to the rate-distortion theory. In order to make use of the statistical dependencies present in the source signal for an additional gain in the signal/noise ratio, the differential pulse code modulation (DPCM) is combined with spherical logarithmic quantization. The resulting method achieves an effective data reduction with a high long-term and short-term signal/noise ratio with an extremely small signal delay.Type: GrantFiled: July 23, 2004Date of Patent: July 12, 2011Assignees: Sennheiser electronic GmbH & Co.

Patent number: 7842131Abstract: The invention relates to a rutile titanium dioxide pigment for use in decorative laminating papers that yields higher opacity of the papers compared to the prior art, as well as a method for its manufacture. The pigment displays a surface coating that contains aluminum phosphate, aluminum oxide, silicon oxide and titanium oxide. The silicon oxide is precipitated in fluffy form. The coated particles display a BET value of at least 15 m2/g. The manufacturing method is characterized in that an aluminum and a phosphorus component are first added to a TiO2 suspension. Thereafter, an alkaline silicon component, an acid-reacting titanium component and, optionally, a further pH-regulating component are added, the pH value being set in the range from 4 to 9 in this context.Type: GrantFiled: January 30, 2007Date of Patent: November 30, 2010Assignee: Kronos International IncInventors: Siegfried Blümel, Lydia Drews-Nicolai, Volker Jürgens, Volker Schmitt

Publication number: 20100078991Abstract: A brake device for braking a vehicle has a brake surface which is rotationally fixedly connected to a wheel axle of the vehicle, a brake lining which can be pressed with a braking force against the brake surface and an actuating element coupled to a control unit, for generating the braking force. The control unit is connected to a speed sensor for measuring a speed of the vehicle and is set up to adjust the braking force in dependence on the speed. The brake device has as high a braking force as possible which is introduced into the brake surfaces. The control unit is coupled to the actuating element via a device for continuous pressure adjustment, so as to enable a continuous adaptation of the braking force to the present speed in each case. The braking force is advantageously adjusted inversely proportionally to the speed of the vehicle.Type: ApplicationFiled: February 4, 2008Publication date: April 1, 2010Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Dieter Maischak, Volker Schmitt

Patent number: 7554277Abstract: A circuit device is disclosed which is used to increase useable motor voltage in a long stator drive. Further, suitable methods for operating a magnetically levitated vehicle provided with the circuit device are also disclosed. In one embodiment of the present invention, the stator section of the long stator drive is connected to the energy supply line on two connection points by way of a first and a second switch. A third switch is located between both connection points arranged on the energy supply line. Both of the stator section connections are connected to the ground potential by way of a fourth and a fifth switch. In one embodiment, in order to accelerate the magnetically levitated vehicle, the first and the second switches are closed and all other switches are opened. The stator section is cross-flown in a direct manner by current in the energy supply line.Type: GrantFiled: October 27, 2005Date of Patent: June 30, 2009Assignee: Siemens AktiengesellschaftInventors: Reinhard Hoffmann, Jörg Lehmpfuhl, Volker Schmitt, Wolfgang Spaeth
