Title: Regeneration of an ion exchange resin bed for the removal of nitrates from water
IPC: B01J49/00
Filed: 1986-10-02
Granted: 1990-12-12
Abstract: A process for the removal of nitrates from drinking water by ion exchange, of the type in which the resin bed , after exhaustion, is regenerated concurrently with the exhaustion flow in successive stages: of expansion of the resin to loosen the bed, of percolation of concentrated brine or other appropriate regenerant, followed by rinsing, also concurrently. The rinsing stage is followed by a homogenisation by mixing the resin particles, this being possible by energetic stirring with highly compressed air, injection of a stream of water or any other means of stirring. An apparatus is described, where the mixing is carried out after the resin exchanger (1) has been drained down to a certain level (h) above the bed, corresponding to an end of a water flow sequence and before filling the exchanger with water for a new treatment. <IMAGE>

Abstract: Method and apparatus for quieting the operation of a dot matrix printer by logically dividing the data to be printed among timed spaced printing passes. A matrix of data to be printed is stored in a memory. A slice of data is selected from the stored data and the number of dots to be printed simultaneously is reduced by logically allocating the data in each slice among complementary submatrices. Each submatrix of data is printed substantially aligned with each other submatrix in two passes of the print head across the print medium to represent the entire selected slice of data. Noise reduction is achieved by reducing the number of data dots simultaneously printed at each print location

IPC: G06F11/26
Filed: 1987-05-19
Granted: 1993-03-31
Abstract: A method for simulating an open fault in a logic circuit comprising field effect transistors utilizes a simulation model which is employed and which takes the fault condition signal storage into consideration by way of an output stage. Given the appearance of a fault-influence signal at the output of a simulation stage, this maintains the through-connection of the signal which appeared immediately before the influenced signal to the simulation model output. In order to take reloading events in the real logic circuit into consideration, this through-connection is canceled after a prescribable time interval.
