Translation of "Grobe verunreinigungen" in English

Coarse contamination of the silver surface should also be avoided.

In this process, coarse impurifications of the cotton are separated.

At least coarse and voluminous impurities are removed from the filter insert 15 .

By visual inspection we can quickly detect coarse contamination of the lubricating oil.

At the cooling water inlet manifold entrance there is a back flow filter 4 in order to retain coarse impurities.

For a coarse filter element, which only filters out coarse impurities, a certain leakage airflow is permissible.

Bag filters 21 are connected upstream of outlet 18 so as to remove possibly existing coarse impurities.

With the aid of aspirated air, dust and husks are separated and coarse contaminants are later outsorted on the primary screen.

Relatively large filler particles or coarse impurities that may be present can thereby be removed from the material to be mixed.

After grinding of the agglomerates, the impurities are separated by screening and the dust fraction is taken out by air flow separation.

In the first step, after shaking the suspension samples with a cotton carrier, whereby the cotton carrier contains the cells to be investigated, the cotton carrier and coarse impurities are removed by pouring the suspension through a nylon screen.

Said waste salts have a maximum water content of 40% and are free of rough organic contaminations such as remainders of dung or urine, blood, flesh, skin and such like.

The patent document DE 35 22 395 Cl also provides for "presoaking" the wastepaper, stacking it in a reaction tower and dissolving it in the tower base by means of a pulper, where coarse contaminations of the wastepaper, for example plastic foils, pieces of wire and similar, can be continuously removed from the fiber suspension.

The separating devices 30, 31 also serve to close the pipe 6, 7 additionally at the bottom and to protect the device in this manner from gross contamination that may be whirled up by the vehicle.

In all cases coarse impurities present in granulated material to be processed can be trapped by a prior-art method in a perforated plate 256 removable from the intermediate hopper 211 and eliminated from the granulated material circulation.

The pore filters, however, can only protect the analyzers against coarse impurities, and have to be changed or cleaned after prolonged usage, because otherwise the measurements will be inaccurate, due to the strong throttling of the line cross section.

As the surface of the clothed roller 4 passes by the waste removal gap 7 provided with the mote knife 8, short fibers and coarse impurities are thrown out of the fiber material through the gap 7 by centrifugal forces which are generated as a function of the circumferential velocity and curvature of the curved roller 4. The trash is collected in a waste chamber 9 in the housing 1.

It is advantageous to space the processing structures in processing channel 3 at distances large enough to prevent a damaging via heavy contaminations or undesired pulverization thereof from occurring.

Filter apparatus according to claim 10, wherein the openings constitute a pre-filter for coarse impurities.

Simultaneously, the intermediate wall 54 with its openings 55 constitutes a pre-filter which retains coarse impurities introduced by the liquid to be cleaned via the supply channels 3 into the distribution space 56 .

The wiper brush as well as the groove scraper primarily serve for brushing rough contaminations off the external surface of the spindle.

This granular purifier comprises a housing 5 having an inlet 11 for the mixture 1 of grains containing coarse and fine impurities.

According to the invention, the feedstock, from which coarse impurities such as metals, glass, and ceramics have been mechanically separated, is thermally degraded to give low-molecular fragments.

As a result thereof, coarse contaminants of the liquid flowing through the filter are still intercepted, as a result whereof serious damage to an appertaining internal combustion engine can be avoided under certain circumstances.

In this known pressure sorter, fiber suspension to be sorted first flows through an upper region of the rotating screen basket having relatively coarse screen openings in order to hold back coarse impurities, from the outside to the inside. It then flows through the lower two-thirds of the rotating screen basket having finer screen openings, from the inside to the outside.

As will be explained below in more detail with regards to FIGS. 2 to 5, the sulfur pieces introduced by the conveyor 34 are melted within the rotating drum 10. Coarse impurities are removed mechanically from the melt, and the molten sulfur is moved to the outside over an overflow 14.

A filter element of this kind is used to prevent coarse impurities from reaching the interior of the appliance which is intended to sterilize the aqueous medium by ultraviolet irradiation and a magnetic field.

So far, coarse pollutions such as hygienic articles, textiles, paper and stones were removed from the sewage by the screen and transported to the disposal site in regular intervals. Now the new pumps pump the sewage with the solids directly to the sewage treatment plant without problems.

This also applies in particular because, during washing, coarse pollutants such as rocks, sand, metals, and environmental pollutants, such as soot emissions and tire particles resulting from abrasion, which are found in street grass clippings, are removed from the biomass, and at the same time the comminution and press devices are protected, because the increased wear that results from such biomass components (which may even make it impossible to carry out the method) is eliminated.

It is advantageous if the step of homogenizing takes place not until after filtration, but before the degassing of the melt, since in this way the homogenization is not adversely affected by any coarse impurities or solid extraneous substances, or unmelted clusters of plastic, and at the same time the subsequent degassing operation can be accomplished effectively and efficiently, with the possibility for almost complete removal of the gas bubbles from the melt.
