摘要:
The invention relates to a filter (1) having a drainage outlet (31), which can be tightly connected to a connecting head (12). It is proposed to use an insertion seal having radially opposite sealing surfaces of an outer seal (23) and an inner seal (24).
摘要:
A filter housing (10) having a raw-side inlet (12) and a clean-side outlet (14) for media to be filtered and a forward-mounted part designed as a cyclone pre-separator (20) including at least one fastening region (32) of a first part (30) made substantially of plastic is fastened to the raw side, and a second part (40) braced between the first part (30) and the filter housing (10). The fastening region (32) of the first part (30) is screwed to the filter housing (10) using metal fastening elements (50, 54, 56, 60), and—at the upper side facing away from the filter housing (10) it has at least one pressing contour (70) for compensating for at least one dimension tolerance of the elements fastened together. The contour is substantially plastic material, which can be deformed by means of applying a force generated by the screwing together of the metal fastening elements (50, 52, 56, 60), in particular which can be melted.

The present invention relates to binder compositions which are based on polymer dispersions and comprise boric acid or salts of boric acid as crosslinking agents, to processes for preparing them, and to their uses.The aqueous binder composition comprises: a) a water-insoluble polymer (P) in the form of dispersed polymer particles having a glass transition temperature in the range from −50° C. to 50° C., obtainable by free-radical polymerization of ethylenically unsaturated monomers M, the monomers M comprising: 80% to 99.9% by weight, based on the total amount of monomers M, of at least one neutral, monoethylenically unsaturated monomer M1 of low water-solubility; and 0.1% to 20% by weight, based on the total amount of monomers M, of at least one monoethylenically unsaturated monomer M2 which carries at least one carboxyl group and/or at least one carboxamido group (CONH2); and b) boric acid and/or at least one salt of boric acid.
摘要:
The invention relates to a high-current contact (3) wherein several individual, electric conductors (6) of a common electric line (7) are soldered to the contact element (5) individually or in groups. According to the invention, the contact element (5) comprises a plurality of recesses (13) into which the electric conductors (6) are introduced. The soldered connection of the high-current contact (3) can be tested in a simple manner.
摘要:
The invention relates to aqueous dispersions of water-soluble polymers of N-vinyl-carboxamides, which are substantially salt-free and comprise anionic polymeric stabilizers having a comb-like molecular structure, processes for the preparation of the dispersions in the presence of anionic polymeric stabilizers having a comb-like molecular structure and the use of the dispersions as retention aids or fixing agents in papermaking.
摘要:
An air deoiling element with a drainage line for discharging the separated liquids, in which the drainage line is integrally mounted to a support member.
摘要:
A filtering device for a spinning head for producing plastic threads. The spinning head has a housing in which the plastic melt flows through a filter element under pressure before exiting the spinnerets. The filter element is provided with a filtering material that is subjected to an axial contact pressure through a distributor device, according to the degree of pressure of the melt. This contact pressure acts upon the sealing edges of the filter element to close the sealing gaps. The special geometrical configuration of the filter element and/or its elasticity guarantee advantageous filtering in terms of energy. The filtering system is resistant to pressure and provides good, permanent sealing.
