Translation of "Kalkablagerung" in English

Any lime deposition which may occur can only be detected at the onset of the drying process.

Depending on lime scale deposits concentrated or diluted (add 250 ml pramex to 500 ml water).

SUMMARY OF THE INVENTION The object of the instant invention is to improve a solenoid valve of the aforesaid type such that the aforesaid drawbacks do not occur and especially such that deposition of calcium in the area between the valve plate and valve seat is prevented.

However, it has been found in practice that the reduction in limescale which can be achieved by this method is barely significant.

The most varied devices or facilities for treating water for prevention of the formation of scale or calcium deposits in water-conducting pipe systems are already known.

The company Emipuls Swiss SA develops, manufactures and sells high-quality devices which protect pipes and all types of devices that use running water against limescale and rust deposits.

For heavier limescale, allow the cleaner to work overnight and use a brush if necessary.

Against the background of the prior art outlined above, the underlying objective of the invention is to propose a composition which combines the cleaning function, the functions of the substances to be added during the final rinse cycle and the function of preventing lime scale if using hard water, these functions being activated at fixed times during a dishwasher rinse cycle, i.e. appropriate functional substances are released in a controlled manner during the dishwasher rinse cycle.

For both alternatives, it is preferable to provide means to ensure that the substance(s) for preventing lime scale deposits in the dishwasher and/or on the washed articles is (are) at least partially released prior to the final rinse cycle.

This electrolysis cell serves to produce oxygen radicals for the inactivation of the microorganisms or also to reduce lime scale.

The strip-form toilet cleaning product according to claim 1, characterized in that it contains further ingredients conventionally present in toilet cleaning products, preferably selected from the group comprising acids, bases, salts, thickeners, antimicrobial active substances, preservatives, complexing agents, bitter substances, polymers, colorants, scents, perfume boosters, fillers, builders, bleaching agents, corrosion inhibitors, erosion regulators, enzymes, microorganisms, active substances for biofilm removal, active substances for inhibiting lime deposits, active substances for reducing adhesion of soiling, active substances for improving processability and mixtures thereof.

The contamination, particularly caused by limescale, can also be determined in another way than by a sensor means.

The limescale deposit and the associated damage to the boiler or pipe wall or the valves can lead to dramatic damage through to functional failure of the equipment and components.

Thus, the limescale deposit which, in uncoated components, was 3.5 g after 300 test cycles, could be reduced to 0.4 g in the case of coated components.

The adherent composition of claim 1, further comprising toilet cleaning agents selected from the group consisting of acids, bases, salts, thickening agents, antimicrobial active substances, preservatives, complexing agents, dyes, perfume boosters, fillers, builders, bleaching agents, bittering substances, corrosion inhibitors, enzymes, microorganisms, active substances for biofilm removal, active substances to inhibit lime deposition, active substances to decrease dirt adhesion, and mixtures thereof.

Owing to the anti-limescale coating, the limescale deposit in oil or gas pipes used to convey or store crude oil or natural gas, in safety valves or sand control systems belonging to the line system, can be significantly reduced or even completely prevented.

If, with the tissue treatments in the prior art, calcium deposit sites such as phospholipids and unstable glutaraldehyde radical molecules are merely chemically bonded, the effect against lime deposition may decrease over time.

Whereas the problem of calcification at the machine side, which can result in an abortion of the dialysis and thus in a non-achievement of the treatment goal, is thus generally known, the effects of the lime deposition in the machine on the calcium supply to the patient have previously only been rarely looked at.

As a result, the energy level E 1 corresponds substantially to the energy level E 2, with the result that, upon determination of these two energy levels, it is established that there is no contamination or scale build-up, i.e., lime deposit, on the translucent element 2 .

If the wetting operation takes place with insufficiently softened water, a lime deposit forms on the translucent element 2, this deposit being determined by means of the above-described measuring method, using the elements 4, 5 .

The method described in WO 02/12790 A1 as well as the device described in this document have been found to be fundamentally useful, since especially the laborious and cost-intensive maintenance work for removal of the lime in the steam generator becomes superfluous, as well as providing maximum heat transfer from the walls to the liquid during operation and not reduced by lime deposits, with the inner rotating components acting so to speak as a scraping device, with which the deposits on the walls are removed instantaneously during the operation, that is, during the rotation.
