  • Publication number: 20120227643
    Abstract: A recycling furnace is provided for processing potentially explosive precious metal-containing materials having organic fractions that combust with great energy. The furnace includes a switching facility for alternating operation of two burning-off chambers of the furnace between: (A) pyrolysis or carbonization under protective furnace gas in an atmosphere comprising maximally 6 wt-% oxygen, and (B) oxidative combustion of the organic fractions including carbon. The furnace has indirect heating and a control that determines the end of the pyrolysis or carbonization by a sensor and controls the switching facility to supply air or oxygen to the interior of the furnace. A continuous conveyor for dosing of liquids or liquefied substances during the pyrolysis is controlled by at least one parameter of post-combustion, preferably a temperature sensor. A single waste gas treatment facility is used for thermal post-combustion for the two furnace chambers.

  • Patent number: 8188329
    Abstract: A recycling furnace and method are provided for processing potentially explosive precious metal-containing materials having organic fractions that combust with great energy, the furnace including a switching facility for alternating operation of a burning-off chamber of the furnace between: (A) pyrolysis or carbonization under protective furnace gas in an atmosphere comprising maximally 6 wt-% oxygen, and (B) oxidative combustion of the organic fractions including carbon. The furnace has indirect heating and a control that determines the end of the pyrolysis or carbonization by a sensor and controls the switching facility to supply air or oxygen to the interior of the furnace. Steps (A) and (B) are carried out sequentially in the furnace chamber, wherein neither the batch is changed, nor the furnace is opened. After the end of step (A) is determined, step (B) proceeds right after the pyrolysis or carbonization by supplying air or oxygen.

  • Publication number: 20080284239
    Abstract: The invention relates to a brake system for a vehicle having at least one brake circuit which includes at least one wheel brake, one inlet valve, one outlet valve, and one return device. The return device has at least one first pump device and one second pump device, having respective inlet valves and outlet valves. The pump devices have a delivery cycle offset from each other. An additional valve is located in every supply line of every pump device for preventing negative pressure produced in an intake phase of one of the pump devices from being applied to an inlet valve of another pump device.

  • Patent number: 7278835
    Abstract: A piston pump for brake systems employs a pulsation-smoothing device that functions especially well in the region of the outlet valve. As a result, substantially less noise occurs, and the durability of the piston pump is substantially better. The piston pump is used essentially in traction-controlled motor vehicle brake systems.

  • Patent number: 7076115
    Abstract: Computer programs and computer-implemented methods implement techniques for evaluating experimental data from a library of materials. The techniques receive a plurality of images of a library of materials that includes an array of members associated with locations in the library. User input identifying a plurality of regions of interest is received. A series of reduced data values is determined for one or more of the regions of interest as a statistical function of a plurality of pixel values for pixels in the corresponding regions. A figure of merit is calculated from one or more of the series of reduced data values for a library member at the corresponding library location. The regions of interest include a plurality of pixels in the images and correspond to locations in the library.

  • Patent number: 6758243
    Abstract: A pressure accumulator has a housing having at least one pressure medium opening, a diaphragm chamber arranged inside the housing and having a side wall which is at least partially deformable, and a pressure medium chamber arranged outside of the diaphragm chamber, the pressure medium chamber at least partially being limited by a partially permeable material which allows an exit of gas from the pressure medium chamber but prevents an exit of a pressure medium from the pressure medium chamber.

  • Patent number: 6738529
    Abstract: Computer programs and computer-implemented methods are disclosed for extracting and analyzing combinatorial chemical data from images. The invention receives a stream of data, identifies a plurality of regions of interest and determines a series of values for one or more regions of interest. The library includes a plurality of members. The data stream includes a series of images of the library. Each region of interest corresponds to a location in each of the images and to a location in the library. The series of values for each region includes a value for each of the images. Particular embodiments have the following features. The invention calculates a figure of merit for a library member from each series of values. The stream of data comprises a series of images generated at a frequency of greater than about 1, 6, 12 or 30 frames per second. The series of images is captured from a beginning of a combinatorial experiment to an end of a commercial experiment.

  • Publication number: 20040045431
    Abstract: The invention relates to a roller bearing, in particular a needle bearing (38). The invention proposes embodying a bearing ring (42) of the needle bearing (38) with a lateral extension (46) with which the needle bearing (38) can be pressed into a bearing seat (48). This has the advantage that a compression of the bearing ring (42) by the bearing seat (48) takes place outside the region of the needles (40) of the needle bearing (38) and consequently, the compression of the bearing seat (48) does not influence a bearing play of the needle bearing (38). The needle bearing (38) is particularly provided for supporting a shaft (24) of a piston pump (16) of a pump unit (10), which shaft supports a cam (26).

  • Publication number: 20030170133
    Abstract: The invention relates to a piston pump (10) for a hydraulic vehicle brake system that has traction control. The invention proposes embodying the piston pump (10) with a piston ring (24), for instance a PTFE, which ring serves as both a sealing and a guide ring. The invention lessens the effort and expense of assembly as well as the production costs for the piston pump (10). To achieve reliable sealing, the invention proposes embodying the piston ring (24) with an internal cone on its side toward a pump chamber (18), so that during a pumping stroke, the piston ring (24) is subjected to pressure from the pump chamber (18) and is pressed into sealing contact against a pump bore (12).
