Title: Impregnation appts. - has two vats and rollers to ensure complete saturation of fibrous material
Inventor: ZANKL WOLFGANG
IPC: D06B1/14
Filed: 1992-03-27
Abstract: Appts. has an immersion roller in a vat. The material is carried across the top of the roller. A second vat and roller in the installation is arranged to impregnate any material unaffected by the first roller. The rollers are placed in close fitting vats. Pref. the roving is taken from a bobbin by a roller system to take up the slack. It travels beneath the first vat and reverses across the roller, with a change of direction to cross the top of the roller in vat. It is then wound up. An accumulation of material on the rollers, is removed by the surface scrapers which are fitted with set-screws. The rollers are between 10 and 20mm wide, with a ratio to the diameter of 1 to 4. The shape of the vat is designed to fit close to the rollers. ADVANTAGE - The treatment fluid is kept in flow at a low temperature. There is a constant flow around the rollers, and suspended particles do not form deposits in the vat, but become homogenous with the material. The fibrous material absorbs fluid to twothirds of its thickness in the first vat, and the same at the opposite side, in the second vat, so ensure total impregnation. The system permits viscous fluids and specialized fibrous material to be handled. The speed can be improved, with less supervision. The installation is practical and economic, and may be extended in a series with a common drive

Patent DE-4232130-A1 (DE)
Inventor: FENNEL HELMUT
IPC: B60T8/173
Filed: 1992-09-25
Abstract: To regulate the flow rate of an electric motor-driven hydraulic pump (6, 6', 18) that is activated by a variable pulse/pulse-break train (UA) and that serves to supply auxiliary pressure to a brake system with ABS and BASR, the generator voltage (UGen) produced by the pump motor (7, M) during times of pulse break (Taus) is evaluated as a measure of pump speed. In a control circuit the set value (USOLL) for pump speed is compared with the actual value (UIST) of the pump speed and the new correcting variable for activating the pump is derived from the difference.
