Patent DE-19854884-A1 (DE)
Inventor: ROMBERGER FRIEDRICH
IPC: E04C2/04
Filed: 1998-11-27
Abstract: The invention relates to a method for producing an at least two-layered external wall element (1) for a building, comprising the following steps: introducing pourable light concrete into a form in order to produce a support layer (3); applying pourable insulating layer material onto the unhardened support layer (3) in order to produce an insulating layer (4) which is integrally connected to the support layer (3); evening out the surface of the insulating layer material and hardening. The insulating layer material is produced by mixing an expanded glass granulate (41) with a cement matrix. According to the invention, fine-grain particles (42) are also added while the insulating material is being mixed. An external wall element (1) produced according to this method has the support layer (3) consisting of light concrete and the insulating layer that is integrally connected to the support layer (3), containing the expanded glass granulate (41) and fine-grain particles (42). This results in a series production-compatible external wall element (1) with high quality surfaces, since the fine-grain particles (42) serve as "lubricants" for reducing the considerable inner friction that occurs between the expanded glass particles (41).

Title: Procedure for controlling a paper feed cycle for a sheet fed printer detects multiple sheet miss-feeds and partial sheet overlays and sets a positioning member to re-direct miss-fed sheets
Inventor: ENGELMANN RUEDIGER
IPC: B65H7/06
Filed: 1999-07-05
Abstract: Procedure compares two signals: one generated by a detector positioned in the path taken by a sheet when it is fed correctly and a reference signal when a sheet is miss-fed. An error signal generated by the comparison can be used to position a positioning member to re-direct the miss-fed sheet. The detector signal is stored over the length of the sheet.  The detector (1) measures the sheet thickness from the strength of light signal received at a receiver (4) from an emitter (3) with signal strength determined by number of sheets, sheet thickness and ink pattern. Hence a calibration procedure is undertaken.
