In a conveyor system with a radiant heating system, convection is provided with hollow elongated tubes having small holes for providing a gentle air flow toward a workpiece to heat the workpiece with convection and radiation.

Apparatus and a concomitant method for electrostatically depositing select doses of medicament powder at select locations on a substrate. Specifically, the apparatus contains a charged particle emitter for generating charged particles that charge a predefined region of a substrate and a charge accumulation control circuit for computing the amount of charge accumulated upon the substrate and deactivating the emitter when a selected quantity of charge has accumulated. Additionally, a triboelectric...

A method for producing a silica glass for photolithography, which comprises the following steps: jetting a starting material gas, an oxygen gas and a hydrogen gas from a burner and depositing and consolidating silica glass powder on a target to form an ingot having a growing direction, where the ingot is grown in such a manner that at least a part of glass synthesis face on the ingot having the silica glass powder deposited and consolidated is a plane substantially perpendicular to the growing d...

The invention proposes a jet device for a machine for producing a material web, in particular a paper or board web, having a nozzle device for dispensing a jet of liquid which is under pressure and is directed onto the material web and/or a transport belt guiding the material web. A changeover device by which the pressure with which the medium impinges on the transport belt or the material web, respectively, can be set.

A machine for terminating a computer chip with one or more stripes of a solderable paste, comprising a feed plate wheel defined by an outer marginal edge and having an upper exposed plate surface inclined to the horizontal against which an inventory of 3-dimensional chips is placed for loading, at least one narrow groove formed in the exposed plate surface directed outwardly toward the marginal edge wall and arranged to pass through the inventory and receive therein at least one of the chips in ...

An apparatus is provided for producing continuous glass filaments. The apparatus comprises a feeder (20) for supplying streams of molten glass to be drawn into continuous filaments, a drawing device (40) adapted to draw the streams into the filaments, and heat removal apparatus (50) located adjacent to the feeder for transferring energy in the form of heat away from a filament forming area adjacent to the feeder. The heat removal apparatus includes first and second manifolds (52a, 54) through wh...

A machine system and process for producing attrition resistant, controlled release fertilizer is described. In the process, a prewet solution is used to initially coat the plant nutrient to be coated followed by the separate application of the individual components used in the coating. The machine system provides an improved means for uniformly applying a single layer or multiple layers of polymer coatings to the plant nutrient.

The invention is directed to a method for producing low sintering fine-particle multicomponent glass powder having a particle size of the primary particle in the nanometer range. The method utilizes microemulsion techniques with subsequent separation of the particles out of the emulsion and calcination for utilization as glass flow having a sintering temperature <900.degree. C. or in a glass flow, for generating thin transparent layers or for generating color decorations on glass, glass ceram...

A method of manufacturing an optical waveguide comprises a first step of laminating, on one major surface of a first glass material, a second glass material to a desired thickness, the second glass material having optical characteristics different from those of the first glass material, a second step of forming the second glass material to have a desired circuit pattern, and a third step of laminating a third glass material having optical characteristics similar to those of the first glass mater...
