Title: Aq. dispersion of dyestuff insoluble in water - esp. vat or disperse dyestuff contains aldose or ketose to complex boric acid and inhibit gelation
Inventor: ERZINGER PAUL
IPC: D06P5/28
Filed: 1980-09-18
Abstract: Aq. dyestuff dispersion contains a dyestuff (I), which is insoluble to hardly soluble in water, and aldose (IIA) or ketose (IIB) and opt. also an anionic dispersant (III), non-ionic dispersant (IV) and/or hydrotropic agent (V). Pref. (I) is a disperse or vat dyestuff, esp. a disperse anthraquinone dyestuff of formula (I), (in which R is H, 1-12C alkyl, lower hydroxyalkyl, cycloalkyl or aryl; W is H, halogen, CN, lower alkyl or lower alkoxy; n is 1 or 2; Z1-3 are H, NO2 or an OH or amino gp., opt. substd. by lower (hydroxy)alkyl, cycloalkyl or aryl. In partic., R is H, 1-4C alkyl, (halo)phenyl, 2-4C hydroxyalkyl, hydroxyphenyl, methylphenyl or methoxyphenyl. Ring A opt. has 1 or 2 Cl or Br substits.; Z2 and Z3 are H, OH or (methyl)amino; Z1 is OH or an amino gp., opt. substd. by R. (II) is pref. a pentahydroxy-aldehyde or -ketone, esp. fructose. Pref. the particle size of the constituents of the dispersion is under 10, esp. under 2 micron. The dye liquor or printing ink can also contain a thickener based on polysaccharides. The dispersions are specified for use in the prepn. of dye baths or printing inks, esp. transfer printing inks for (polyester) fibres. Since (II) are strong complexing agents for boric acid, they inhibit gelation and eliminate the need to remove boric acid from the crude (I).

Patent DE-3044073-A1 (DE)
Inventor: KEIL ERICH HELMUT
IPC: D01D5/12
Filed: 1980-11-24
Abstract: Polyesters are drawn in the form of thick tows in a predrawing and a main drawing step. Predrawing is carried out at 71 DEG -90 DEG  C. in water, and the predraw ratio is chosen in such a manner that the main drawing can be carried out at a minimum of draw tension. Between predrawing and main drawing, the tows cool to below 40 DEG  C. Suitable draw ratios for the predrawing are from 1:1.05 to 1:1.6. The main drawing is carried out either in steam or hot water. FIG. 2 shows the curve of draw tension in the main drawing step as function of the draw ratio in the predrawing: there is a distinct minimum.

Title: Process for emptying pressurised dispenser lines
Inventor: MALLEK HEINZ DIPL ING
IPC: B08B9/02
Filed: 1981-06-12
Abstract: A process and an apparatus for carrying out the process which for example forces out the contents of beer lines by means of CO2 gas after use, are described. Filled beer lines, after stagnating for more than three hours, deposit marked slimy residues on the walls. When beer withdrawal is resumed, several glasses must first be discarded (approximately 1 litre for a 4-meter long line). The beer is then usable again. In the present process, the contents are forced out of the line from the CO2 system present in each dispensing system with the aid of an apparatus. The line emptied in this manner is under a CO2 atmosphere. The line remains free of slime. The beer is immediately usable on renewed dispensing. The process enables     1. beer to be hygienically dispensed and 2. the conservation of foods and thus direct material profits of several hundred DM per month and dispensing system. e

Patent DE-3131945-A1 (DE)
Inventor: LECHNER ERNST-FRIEDRICH
IPC: H01R43/00
Filed: 1981-08-12
Abstract: In wrapping a wire around a pin, the turn being produced is rolled against the pin by a tool surface (21) which rotates with the wrapping motion, so that defined and reproducible contact areas are created. As far as the forces are concerned, the contact-making and wrapping are decoupled from each other; the tension of the wire therefore needs to be designed only still for the wrapping process proper.

Abstract: A ball swivel joint comprises a stub which ends in a hemisphere with a larger diameter, the hemisphere being arranged in a socket and having a hemispherical recess which is in engagement with a hemispherical convex surface of a bearing retention element arranged in the socket or, alternatively, of integral design with the socket. The bearing retention element or, alternatively, a segment of the inner surface of the socket engaging with the circumferential surface of the hemisphere is elastically preloaded in a direction in which firm engagement of the various bearing surfaces in mutual contact is ensured and, among other things, this compensates for wear. The ball swivel joint according to the invention can transmit considerable forces within a wide angular range between the stub and a shaft or the like rigidly connected to the socket.
