Patent DE-19822505-A1 (DE)
Title: System to apply a liquid or paste coating to the surface of a moving web
Inventor: UEBERSCHAER MANFRED
IPC: D21H23/32
Filed: 1998-05-19
Abstract: To apply a coating of a liquid or paste (18) to the surface of a moving web, the volume of delivered coating medium (18) is reduced per time unit at the applicator (16), when the monitored coating weight exceeds a nominal value.  When the coating weight is below the nominal value, the setting force at the dosing unit (22) is reduced. The corrective actions are stopped when the delivered volume of coating (18) at the applicator (16), per time unit, reaches the lower threshold and/or the setting force on the dosing unit (22) reaches and/or drops below a lower threshold. The corrective actions are applied to maintain a constant pressure of the dosing unit (22) through the setting force on one side and the coating (18) medium build-up against the web (12a) on the other side, or the setting angle of the dosing unit against the web. The coating weight is registered by a sensor system (26,28,30).  The initial sensor (26) determines the material weight of the web (12) before coating.  At least one further sensor (28) monitors the web weight after coating. A unit (30) records the difference between the sensor readings, to give the coating weight.  The sensors (26,28) are set to give position readings for a number of web sections across the web width. A control unit (34) alters the setting force on the dosing unit (22), according to deviations in the coating weight from a nominal value. The dosing unit (22) is a doctor blade or doctor rod, to set the lateral and/or longitudinal profile of the coating layer (32).

Title: Compression of potentially explosive gases through injection of liquid into a common vessel
Inventor: PIEPERBECK BRUNO
IPC: F04B39/00
Filed: 1998-10-20
Abstract: The equipment consists of two vessels; (B1), in which the compression takes place and (B2) that is a reservoir for the liquid. Of these, B2, which is vented to atmosphere, has the greater volume.  Preferred Features: The vessels are linked by piping so that the levels of liquid are the same initially. Gas (GE) enters near the top of B1. The inlet valve (PVE) is closed, valves in the linking pipelines are closed and pump (PU1) is started. The liquid level in B1 then rises and the gas is compressed until its pressure opens a relief valve (PVA) set to the required final pressure. The liquid level rises until its highest permissible level is shown at (LS+). The pump is then stopped, the inlet gas valve is opened and the connections to the reservoir B2 are opened. The falling liquid in B1 then draws in another charge of gas. Pressure and level meters send signals to a processor (u) that controls the functions of the liquid valves. A final gas pressure of 2 bar is visualized.
