Patent number: 11813647Abstract: A valve has a plurality of material inlet ports, a flushing inlet port, and an outlet port each connected to a respective supply of one of last two different liquid materials. A movable valve body in the valve has a passage and is shiftable between a plurality of positions in each of which a respective one of the inlet ports is connected to the outlet port via the passage. A controller moves the valve body between the positions such that, after each time the valve body is in a position connecting one of the material inlet ports to the outlet port and material has passed through the passage, the valve body is moved into a position connecting the passage with the flushing inlet port for flushing out the passage.Type: GrantFiled: June 1, 2022Date of Patent: November 14, 2023Inventors: Michael Saier, Lothar Weber

Patent number: 10350803Abstract: An injection molding apparatus is used for making parts having a hollow portion that is disposed under an angle relative to an axis. The molded parts are ejected when a movable stripper plate is displaced relative to the mold core used to cool the angled portion of the molded part. The stripper plate includes cooling channels and a cooling outlet. The cooling outlet is coupled to a cooling inlet of a movable cooling slider element. Leakage of a cooling fluid is prevented by using a sealing device and sealing elements between the cooling slider and a cooling manifold retaining the mold cores when the stripper plate is used during the ejection of the molded parts from the mold cores.Type: GrantFiled: June 29, 2016Date of Patent: July 16, 2019Assignee: OTTO MÄNNER INNOVATION GMBHInventors: Klaus Bohn, Lothar Weber

Patent number: 6156430Abstract: The invention essentially relates to the use of ceramic powders whose surface has been rendered hydrophobic to produce fine-particle dispersions having a high solids content and a low viscosity. The invention further relates to specific ceramic powders whose surface has been rendered hydrophobic, and methods of producing them. Ceramic powders whose oxidic surface has hydroxide groups possessing a basic or amphoteric character can be rendered hydrophobic, for example, through the effect of a hydrophobic carboxylic acid. Acidic oxides are rendered hydrophobic through treatment with metal-containing hydrophobing agents which are, however, also suitable for rendering ceramic powders hydrophobic that have a basic or amphoteric character.Type: GrantFiled: July 30, 1997Date of Patent: December 5, 2000Assignee: Robert Bosch GmbHInventors: Lothar Weber, Ulrich Eisele, Ruediger Nass

Patent number: 5550424Abstract: A spark plug for igniting fuel/air mixtures in internal combustion engines, in particular in internal combustion engines of motor vehicles. On its insulating-body foot, the spark plug has a coating which is intended to protect against misfirings and cold-starting difficulties as a consequence of electrically conductive deposits, in particular in the case of installation of spark plugs in new motor vehicles. The coating includes solvent-free silicone rubber or silicone resin. The silicone rubber may contain filler and is provided with silicone oil for the purpose of good processability. Expediently, the inner side of the metal housing which is exposed to the combustion chamber is also covered with the coating. The coating is physiologically safe, environmentally acceptable and resistant to handling, and does not require expensive extraction systems if it is sprayed onto the appropriate region of the spark plug by means of nozzles.Type: GrantFiled: June 5, 1995Date of Patent: August 27, 1996Assignee: Robert Bosch GmbHInventors: Irene Jennrich, Lothar Weber, Andreas Niegel

Patent number: 4787717Abstract: A pigment is mixed with an epoxy resin or varnish binder in a weight ratio from 5:1 to 6:1 to make a paste, which is then applied as a thin layer by screen printing on top of the counterelectrode layer previously baked onto a metal substrate. In another baking step the new layer for producing a reflective coating is heated to between 120.degree. and 180.degree. C., in which temperature range the binder produces small bubbles before hardening, so that the layer that is produced is permeable to ions when the layer becomes soaked with electrolyte in the assembled electrochromic device. The metal substrate is shaped by drawing to provide the electrolyte cavity after the application of the counterelectrode and the reflecting background layer thereon, since the deformation does not damage either of these layers.Type: GrantFiled: March 22, 1983Date of Patent: November 29, 1988Assignee: Robert Bosch GmbHInventors: Jutta Heinz geb Belgardt, Helmut Sautter, Rainer Schink, Lothar Weber

Patent number: 4780332Abstract: A screen-printing paste containing Cu.sub.2 O or NiO and preferably aluminum oxide or, more preferably, an aluminum compound such as aluminum acetylacetonate which forms aluminum oxide under calcination heat, is printed over an entire surface of a substrate consisting of aluminum oxide ceramic, after which it is calcined in air at from 800.degree. to 1350.degree. C. to produce an adhesion-promoting spinel layer. That layer is then metallized by plating in an electroless bath for deposition of copper or nickel, as the case may be, after which the metal layer thus deposited is reinforced galvanically.Type: GrantFiled: October 8, 1986Date of Patent: October 25, 1988Assignee: Robert Bosch GmbHInventors: Birgit Pitz, Helmut Sautter, Lothar Weber
