THICKENED AQUEOUS NO- OR LOWPHOSPHATE BUILT CLEANING COMPOSITION A no- or low-(less than 0.01%)phosphorus built liquid automatic dishwasher detergent composition is based on a mixture of aluminosilicate zeolite and a bleach-stable, water-soluble, carboxyl group-containing polymer, such as sodium polyacrylate, of relatively low molecular weight, to achieve comparable cleaning performance to a phosp...

In order to carry out the measuring method according to Patent No. 393 738 (A 68/89), a device is proposed which has a loudspeaker 1 arranged in a resonant cavity 2 with a tubular sound exit opening 3. The resonant cavity 2 is arranged via a spacer 4 at a spacing from the tube (pipe) 6 in which the gas or liquid column whose length is to be determined is contained. The spacer 4 also carries a rece...

The object of the invention is to provide a theft-proof and vandalism-proof storage facility for bicycles which is suitable to be set up in the region of public facilities. A further requirement is to accommodate as many bicycles as possible in an extremely small amount of space. In the case of the present container, a cuboidal frame structure 1, which is large enough for a bicycle to be garaged t...

New monospecific antibodies (Ab), esp. monoclonal mouse Ab, react in an ELISA test with a NIC-OH conjugate (NIC = 1-methyl-10alpha-methoxy-dihydrolysergol), esp. NIC-17-hemisuccinate/BSA (bovine serum albumin) conjugate, but in a similar test system will not react with underivatised carrier (BSA). Also new are (1) similar antibodies (Ab') specific for a BNS conjugate (BNS = 5-bromonicotinic acid),...

On the side of a base bar (1) is located a bearing block (4) for a swivelable guide ruler (6) with two rails, between which is guided a cutter bar (8) with at least one blade (9). The cutter bar is engaged by a hauling member (10), guided by a deflector (11) at the guide ruler end, away from the bearing block. The guide ruler is held in its cutting and compression position by an arrester (20). Pre...
