Patent DE-4201427-A1 (DE)
Inventor: WREDE ULRICH DIPL ING
IPC: B04B1/20
Filed: 1992-01-21
Abstract: The solid bowl worm centrifuge is used to separate a 2-phase liquid mixture containing solids. The product to be separate is taken to a drum (1) via an intake pipe (11), passes via an intake aperture (10) into a distributor pipe (7) which rotates with a worm (2) fitted in the drum (1). In the distributor pipe (7) the product is accelerated to the rotation speed of the worm and then passes through two outlet apertures (8, 9) into a separating region "T" between the two liquid phases without having to pass through one of them. This not only accelerates the product carefully but also results in crossing-free product feed, thus improving the separator results in both separated liquid phases.

Title: Ring spinner control - has program for spindle speeds and cop winding to vary nominal values automatically and maintain constant yarn tension
Inventor: BAIER FRANK DIPL ING
IPC: D01H1/34
Filed: 1992-09-21
Abstract: To determine the nominal spindle speed, esp. for the spindle drive at a ring spinner to give automatic changes from the nominal value as the cop size increases, nominal value changes are set into the operating program as different function types in steps of 20-1000 steps. Spinning parameters are coupled to the selected changes in spindle nominal values, in the operating program, for transfer to the machine control. In operation, the nominal value is adjusted on line according to the actual values as required. The changes in the nominal values are effected automatically and proportionally either to the spindle speed or the amount wound on the cop according to the value of the other parameter. The settings are inserted for the spindle speed or cop winding to cover start-up, main spinning and the end of spinning, with splicing. Pref. the parameters for each spinning section take in the start and end speeds and the amount wound on the cop, or the type of function to change the spindle speed, the number of step changes in the speed or cop contents and the acceleration between steps. The various function types ensure short start-up and end times to give a constant draw tension on the yarn. ADVANTAGE - Consistent yarn quality through all stages of the spinning and winding process, with reduced yarn breaks. Gives a variety of spinning programs for automatic working.
Patent DE-4232992-A1 (DE)
IPC: C02F3/04
Filed: 1992-10-01
Abstract: Trickle filters (13) comprising microorganism-colonised packings (17) serve for the biological purification of exhaust air. The microorganisms are constantly irrigated with a liquid. In this case, their surface is covered by a liquid film. This decreases the biodegradation efficiency of known trickle filters (13). According to the invention, the microorganisms of the trickle filter (13) are only irrigated to the extent that they are moist in the interior, but their surface is not wetted by the irrigation liquid. As a result, the exhaust air to be purified receives direct contact with the microorganisms which has as a consequence an increased biodegradation efficiency of the pollutants contained in the exhaust air. The process according to the invention is particularly suitable for removing water-insoluble contaminants from exhaust air of industrial processes. <IMAGE>
