Title: Water softening system - based on bottle neck with permanent magnet
Inventor: FLAMMANN NORBERT DIPL ING
IPC: C02F9/00
Filed: 1989-09-29
Abstract: Small quantities of hard water are softened for use in coffee machines or steam/spray/dry irons by a permanent magnet treatment.

Title: Measuring warp angle of textile material on conveyor during mfr.
Inventor: VERCRUYSSE MICHEL DIPL-ING
IPC: D06H3/12
Filed: 1991-04-11
Abstract: Determining the warp angle of a textile material on a conveyor involves sensing the material with a sensor (4 7) position w.r.t. the conveyor direction and to the warp angle. Components statistically independent of the warp angle are filtered out of the signal.     The filter transmission characteristic, centre frequency, bandwidth and/or filter characteristic are adjusted using the signal from a second sensor which depends on the warp angle dependent components of the first signal. The filter characteristic is thus matched to the warp angle dependent components.

Title: Stomach rumen contents disposal of slaughtered beef - uses mechanical and indirect drying before burning with enclosed gas system to contain smells
Inventor: SCHU GEORG F DR ING
IPC: A22B5/18
Filed: 1991-06-08
Abstract: To dispose of the contents of stomach rumen, in slaughtered beef, part of the water content is extracted mechanically and then it is dried indirectly through heat feed without ingress of false air from the rising water vapour which is sucked clear. The dried material is carbonised under vacuum at low temp. to produce ashes for removal and low temp. carbonising gas. The gas is passed to a burner to be consumed with flue ash and exhaust gas. The exhaust gas is used as thermal energy for a heater. The combustion gas is used to generate steam, and part of the steam is returned to given an indirect heating to the rumen contents. The exhaust gas, on leaving the burner is burned further before reaching the heating vessel. The water vapour rising from the rumen contents during drying is mixed with the exhaust gas from the cyclone burner. Part of the water vapour from the drying material, or all of it, can be condensed and the condensn. passed to the waste water outlet with conden. heat used for hot water supplies. ADVANTAGE - The technique gives a safe and tolerable disposal of the rumen contents, with incineration without smell and effective drying before burning.
