Publication number: 20070084162Abstract: An apparatus for purification of air comprising comprises a housing having inlet openings for supplying the air to be cleaned and outlet openings for discharging the cleaned air, a filter system disposed in the housing, and a fan arranged to draw air through the housing and filter system. The filter system includes at least one tubular or bag-shaped fleece filter which is arranged on top of a carrier structure and at least one secondary filter element which has a filter fineness which is smaller than the filter fineness of the fleece filter. The entire apparatus is arranged either stationarily or moveably in regions of greater to lesser dust concentration. The cleaned air is conveyed to the region with the higher local dust concentration and thereby significantly decreases the local dust concentration.Type: ApplicationFiled: September 13, 2006Publication date: April 19, 2007Applicants: Mann & Hummel GmbH, Keller Lufttechnik GmbH & Co.

Patent number: 6650121Abstract: A sensor for the monitoring of an NOx catalyst having a storage material for the adsorption of NOx, the storage material forming the sensitive element of the sensor. As a result, it is possible to measure the instantaneous degree of charging of the storage material, and a quasi-linear control for the storage of NOx is made possible. The ability to precisely monitor the degree of charging of the storage material makes it possible to better utilize the storage capacity, and the catalyst can be dimensioned in a more cost-effective manner. The conversion phase of the rich side can be predicted more precisely and consequently be integrated more favorably into the driving cycle. The sensor for the monitoring of an NOx catalyst is especially suitable for installation in the exhaust path of an internal combustion engine with direct gasoline injection or of a diesel engine.Type: GrantFiled: September 6, 2002Date of Patent: November 18, 2003Assignee: Robert Bosch GmbHInventors: Dieter Seipler, Bernd Schumann

Patent number: 5418465Abstract: A sensor for measuring the mixture ratio of liquids, particularly of fuel mixtures, comprises a measuring cell, which has a cavity with one inlet and one outlet. The liquid is directed through the cavity, whereby regions of the inner wall of the cavity are electrically conductive and, together with at least one additional electrically conductive surface, form a capacitor, which is a component of an evaluation circuit. The measuring cell is manufactured from at least two ceramic carriers, which are connected by way of at least one connection layer to form a layer arrangement. The cavity is produced between the ceramic carriers as the result of the lack of at least one connection layer in certain regions. In each case, at least one electrode is applied, in the vicinity of the cavity, to the ceramic carrier delimiting the cavity using thick-film technology.Type: GrantFiled: June 22, 1993Date of Patent: May 23, 1995Assignee: Robert Bosch GmbHInventors: Dieter Seipler, Botho Ziegenbein, Bernd Maihoeffer

Patent number: 5266745Abstract: A thick film hybrid arrangement has a plurality of ceramic foils provided with conductor paths and superimposed over one another, a support for supporting the ceramic foils, and a plurality of thin metal lugs located between the ceramic foils for contacting the conducting paths. The metal lugs extend outwardly beyond at least the ceramics foils so as to form outer contacts.Type: GrantFiled: September 16, 1991Date of Patent: November 30, 1993Assignee: Robert Bosch GmbHInventor: Dieter Seipler

Patent number: 5107708Abstract: In an acceleration pick-up (11), the bending spring (13) is a substrate plate, e.g. produced from Al.sub.2 O.sub.3, which is arranged at one side on an elevated portion (12) of a support (10) produced from mechanically rigid material. Accordingly, the resistors (19 to 22) and particularly the evaluating circuit (24) on an elevated portion (12) of the support (10) can be arranged jointly on the bending spring (13) and applied in a single work step using thick-film technology. In addition, a cut out portion (14) is formed in the bending spring (13), so that two bending webs (15, 16) can be formed at the greatest possible distance from one another. Two of the resistors (19, 21) are arranged on the bending webs (15, 16) and one of the remaining resistors (20, 22) is arranged in the area of the cut out portion (14). Accordingly, an electrical monitoring of the mechanical state of the bending spring (13) is made possible.Type: GrantFiled: January 3, 1990Date of Patent: April 28, 1992Assignee: Robert Bosch GmbHInventors: Dieter Seipler, Jiri Marek, Botho Ziegenbein, Martin Holland

Patent number: 5068714Abstract: To adhere a semiconductor chip or wafer substrate (10) to a carrier plate substrate (11) of, for example, ceramic, glass or the like, in which the two substrates carry exposed connection pads (13, 16), at least one of the substrates is coated with an adhesive electrically insulating, normally tacky material, which is exposed, by photo-masking technology, in all areas except those where the pads are located, to cure the material. Metallic powder, typically silver, is then introduced into the remaining tacky portions of the layer, to render it conductive, and the two substrates are then pressed against each other, with the pads in alignment, the metal powder within the tacky insulating material forming an electrical connection between said pads. The insulating layer can be applied either to the semiconductor chip or wafer substrate or to the carrier plate substrate, or to both.Type: GrantFiled: December 14, 1989Date of Patent: November 26, 1991Assignee: Robert Bosch GmbHInventor: Dieter Seipler
