Title: For the disinfection of used paper materials it is compressed to extract the residual air for intensive heating followed by dispersion with added chemicals if required
Inventor: DOCKAL-BAUR JUERGEN
IPC: D21B1/02
Filed: 1998-10-02
Abstract: To destroy germs in materials containing paper fibers, the infected material (M) is initially degassed virtually completely. It is then heated (1) intensively at least at 80 deg C, followed by dispersion (2). For special handling, chemical additives (CH) are introduced into the process. The material (M) has a residual air content of  <= 1 vol% before or during the heating stage (1).  The degassing is to give a pref. residual air content in the material (M) of  <= 0.1 vol%. The material (M) is compressed (3) without affecting its water content, at least to a compression stage where the gas-filled hollow zones take in the residual air content. Or the compression changes the water content to give it a solid content of \-15% and pref. 20-35% with a resulting air extraction, directly followed by heating (1). Before or during heating, the compressed material (M) is loosened and flushed with vapor and pref. steam, which also raises the material temp. The steam flow is against the direction of material (M) travel. After the compressed material (M) has been expanded and/or loosened, it is heated to at least 120 deg C, and held in a stack or a flow path for a dwell time of at least 2 secs. at 120 deg C. The material is dispersed (2) or kneaded, directly after the heating stage (1). In preparation for the heating stage (1), the material (1) is mixed with peroxide at a level of at least 4% of the material dry content. The heating is applied without the use of reduction chemicals. The material (M) has a solid content of 15-80 mass%, mainly of used paper. An Independent claim is included for an appts. with a compression stage connected directly to the heating stage, to feed compressed material plugs into the heater. The heating stage has a gas exhaust, and a steam flushing system using steam from the exhaust.

Title: Wiring level production on a support, especially for multilayer circuit board production, involves leaving an exposed and developed photosensitive resin layer as insulation between conductive regions
Inventor: POHL GERT
IPC: H05K3/18
Filed: 1999-03-10
Abstract: Circuit board wiring level production on a support involves leaving an exposed and developed photosensitive resin layer as insulation between conductive regions. Production of one or more overlying circuit board wiring levels on a support comprises:  (a) applying a metallization nucleating layer over the entire support surface;  (b) applying a photosensitive resin layer on the nucleating layer;  (c) lithographically structuring the resin layer by exposure with a circuit pattern and developing for resin removal from the circuit regions to be metallized; and  (d) selectively growing metal in the circuit regions by electroless plating to form a corresponding wiring level metal layer.  An Independent claim is also included for production of one or more overlying circuit board wiring levels on a support by:  (a') preparing the support and a metal foil carrier; (b') applying a photosensitive resin layer (2) on one or both sides of the foil carrier;  (c') lithographically structuring the resin layer by exposure with a circuit pattern and developing for resin removal from the circuit regions to be metallized;  (d') selectively forming a wiring level metal layer (5) in the circuit regions;  (e') joining the support to the wiring level side of the structure; and (f) removing the foil carrier.  Preferred Features: The metal foil carrier consists of several overlying separable foil layers and the foil carrier removal step (f) involves stripping a foil layer from an adjacent foil layer. When the resin layer (2) is applied to both sides of the foil carrier, the foil carrier removal step (f) involves stripping two foil layers from adjacent foil layers. The foil carrier comprises a strippable thick metal foil layer (1a) having a thin metal foil layer (1b) on one or both sides. One or more further overlying wiring levels may be formed after metal layer formation and before application of the support. Joining of the support and the structure is carried out using an interposed prepreg or adhesive foil layer. In the second process, the metal layer may be formed by electroplating or electroless plating.
