  • Patent number: 4419260
    Abstract: In the production of a spray-dried detergent containing a silicone/silica mixture as an antifoaming agent, the aqueous silicone-free detergent slurry (A) is combined in the range of the spray nozzle or in the pressure line leading to the spray nozzle under conditions whereby substantial mixing is avoided in order to avoid loss of the antifoaming action, with an aqueous dispersion (B) which contains the liquid antifoaming silicone agent, which is present in a particle size of from 0.5 to 40 .mu.m, as well as a film-forming, high-molecular-weight polymer which is soluble or swellable in water, and which is suitable for the formation of microcapsules, preferably a cellulose ether. The microcapsules are formed during the combination of the mixture (A) with the dispersion (B) at the time of spraying, or in the dispersion itself, if electrolyte salts were added to the latter before spraying.

  • Patent number: 4417596
    Abstract: A filter-cleaning apparatus comprises a hollow, elongate body provided with cleaning fluid inlet and exit means at respective ends thereof. The cleaning fluid inlet means comprises an annulus which extends peripherally around one end of the hollow body and which defines together with the outer wall of the hollow body a space for receiving cleansing fluid from a source of such fluid. The interior of the hollow body communicates with the space defined by the annulus through a series if holes formed in that part of the wall of the body located within the confines of the space. When cleaning a filter, the filter is inserted into the hollow body through the inlet means herefore and the source of cleaning fluid activated. The filter is then moved axially in the hollow body, past the series of holes, until all the filter has been cleaned. A closure means is provided at the cleaning fluid inlet, to prevent the escape of cleaning fluid during operation.
