Patent DE-4132474-A1 (DE)
Inventor: KELLER GUENTER DIPL ING
IPC: B02C4/02
Filed: 1991-09-30
Abstract: In order to construct grinding rollers of rolling machines, in particular of high-pressure roller presses, for the pressure crushing of granular material in such a way that the surface regions of the grinding roller that are exposed to wear have an extremely high resistance to wear, according to the invention a multiplicity of wear-resistant material pieces are inserted into these surface regions in such a way that the wear response of the grinding roller at these points is determined virtually exclusively by the wear-resistant material inserted. By varying the size and number of pieces as well as the material properties of the material pieces inserted, it is possible for the wear of the grinding roller to be matched to the substances that are to be crushed in different ways, and to minimise said wear. In particular it is possible to ensure by pinpointed local insertion that previously preferred points of wear on the grinding roller are particularly protected against wear, and thus the wear pattern of the grinding roller remains uniform even over lengthy periods of use.

Title: Protein sepn. by column chromatography - uses silica gel coated with double lipid layer
Inventor: BAYERL SYBILLE DR
IPC: C07K1/20
Filed: 1992-05-26
Abstract: Chromatography gels are prepd. by coating pure silica gel with a double layer of lipids and are subsequently used to separate proteins by column chromatography. Also claimed are similarly coated chromatographic materials (unspecified) other than silica gel. The lipid layers, esp. comprising a phospholipid, partic. phosphatidylcholine, are applied to the silica surface e.g. glass or amorphous quartz beads, as minute unilamellar vesicles by spontaneous adsorption and fusion. The gels can be adapted to particular proteins by providing layers having positive or negative charges e.g. by modifying the coated gel using negatively-charged lipids or positively- or negatively-loaded amphiphilic molecules. Also a two- or multi-component lipid mixt. can be used to produce a surface charge pattern. USE/ADVANTAGE - The gels, which are inexpensive and simple to prepare, increase yields of sepd. proteins and facilitate the sepn. of highly sensitive proteins. They have a biocompatible surface and do not give rise to protein denaturing.

Inventor: HETZENEGGER JOSEF DR
IPC: C09D11/037
Filed: 1992-07-31
Abstract: Lustrous pigment (I) is based on a flaky substrate (II) coated with basic organic colourant of the formula: F-(Z-X)m (III); where F= an n-valent colourant radical; Z= a bridging gp; X= a basic gp; and m= 1-4.

(I) has good properties for application eg strong lustre, high colour purity, interesting colour effect, high mechanical strength and better opacity than usual. (III) adheres well and uniformly to (II). Interesting 2-tone-pigments are obtd if the absorption colour of (III) and interference colour of (II) are different, whilst intense colours are obtd if they are the same. In an example, 0.5 g bis(5-methyl-imidazol-4-yl-methyl)-Cu phthalocyanine was dissolved in 200 g 25 (wt)% acetic acid at 80 deg C. 100 g TiO2 coated mica pigment were dispersed in this soln for 5 min, then 660 g 5% aq NaOH soln was dripped into the stirred dispersion in 2 h, until the pH was 7.0 +/- 1. After stirring for 30 min, the pigment was filtered, washed salt-free with water and dried. In a 10% polyester-CAB lacquer on cardboard, the colour flop was red to blue.

Title: Agent to protect trees from being nibbled by game - has a dispersion powder of homopolymers and copolymers as an aid to adhesion
Inventor: GUBISCH ERWIN
IPC: C08K3/013
Filed: 1992-09-03
Abstract: An agent for protecting against ribbing by wild animals consists of 200-500 pts. wt. slaked drive, 10-100 pts.wt. dispersion powder of homo- or co-polymers as an aid to adhesion, 200-700 pts.wt. fillers, an effective amt. of a deterrent for mild animals and opt. thickeners, antifoaming agents and.or agents to and flowing (?) Pref. the dispersion powder of homo- and co-polymers has a minimum film-forming temp. (MFT) below 20 deg.C and is based on vinyl acetate homopolymers and vinylacetate ethylene copolymers. The filler is ground dolomite. The agent contains 1-15 pts.wt. thickener chosen from polyvinylalcohols, water-soluble cellulose derivs. and polyvinyl pyrrolidone and 1-20 pts.wt. flowing and, chosen from casein, sodium gluconate and melamine-formaldehyde derivs. 2-10 pts.wt. defoamer based on alcohols or silicone oils and 0.1-15 wt.% of the deterrent for the animals. before application to the trees, the agent is mixed with water in wt. ratio agent: water 1:1-1:2. USE/ADVANTAGE - The agent can be used to protect trees, esp. young saplings from damage due to being nibbled by wild animals. The agent adheres very well to trees, and the length of time it remains in place is many times greater than is the case with conventional agents which contain only slaked line as the binder. The adhesion is at points and no water- and air-impermeable film is formed (unlike when polymer dispersions are used as the binder). The agent is more economical and environmentally friendly than previous agents. The binder components gradually crumble as they weather and, on account of their composition act as a fertilisation promoting tree growth. The agent is also easy to handle, easy to transport and need only be mixed with water at the site of application.
