Patent DE-4003519-A1 (DE)
Title: Synthetic fibre sliver processing - is given a temporary false twist after converting before laying in a can
Inventor: GILHAUS KONRAD F DR ING
IPC: B65H57/00
Filed: 1990-02-06
Abstract: To convert sliver material of man-made fibres to spinning, by compression or chopping, the sliver is temporarily twisted as a false twist before it is laid in the can, after it has been processed. The treated sliver is given 3-20 twists/m, and pref. 5-10 twists/m in a fixed ratio to the delivery speed from the compression or chopping stage. A twisting unit (29) for the sliver (27) is after the rollers (28) delivering it from the process stage. The twisting unit (29) defines a further clamping point (K2) to impose a temporary twist in the material. The drive (38) for the twisting unit (29) is coupled to the drive to carry the sliver (27) at the compression or chopping converter (3). The twisting unit (29) has a rotating tube (32), pref. with a smaller cross section at the entry end.  It rotates round its longitudinal axis, while the sliver (27) is fed through, and forms a defined clamping point (K2) for the sliver at the outlet end away from the delivery rollers (28), using a deflection wedge (43) where the sliver (27) moves over its peak (44) facing an opening (45) in the tube (32). ADVANTAGE - The sliver material is stable within its laid coils, and can be withdrawn from the can cleanly and without snagging and at high speeds.

Title: Large scale prodn. of cooked blood broth - forr culture of e.g. haemophilic bacteria, involving proteolytic digestion of blood proteins
Inventor: KLUDAS KARL-HEINZ DR
IPC: C12N1/20
Filed: 1990-05-31
Abstract: In the prodn. of cooked blood broth for appropriate bacteria by addn. of nicotinic acid amide adeninedinucleotide (NAD) and/or haemoglobin (Hb) as growth factors, the new feature is that blood proteins, after proteolytic degradation, are held at 60-80 deg C for 5-10 mins. then sterile: filtered conventionally. The proteolytic enzyme used is one which splits the protein into free amino acids at 25-50%. USE/ADVANTAGE - The broth is used to grow e.g. haemophilic bacteria for diagnosis (in human or veterinary medicine) and vaccine prodn. Unlike known methods, this proceudre allows large batches of broth to be produced, and eliminates the need for addn. of peptone (supplementary N source) since the blood proteins are denatured by enzyme treatment not by heating.

Title: Selective alkaline etching soln. for copper and copper alloys - useful in brasses and bronzes, even when lead is present, completely removes copper to exclusion of nickel
Inventor: BACHER WALTER DR
IPC: C23F1/34
Filed: 1990-08-06
Abstract: An effective etching soln. is claimed for the selective removal of Cu or Cu alloys from a Ni substrate. This soln. is alkaline (pH adjusted to 9-11 by NH3) and contains, (g/l) a metal or NH4 chlorite 3-90; and a metal or NH4 carbamate 50-200. USE/ADVANTAGE - Fully removes Cu to the exclusion of Ni. Useful in situations when other etching agents cannot be used, e.g.  for certain bronzes and brasses, and esp. when Pb is present. In an example, precisely weighed plates of the purest Cu and different Cu-Zn alloys (including those contg. Pb) and Cu-Sn alloys were mechanically treated by ultramilling to a Ra value of less than 15 micron, then galvanically coated with Ni on one side. The Cu was then removed by placing in a soln. made from deionised water and contg. (g/l) NaClO230 and (NH4)(OCONH2) 122, and the pH adjusted to 10 by NH3 at room temp. for more than 1 hr. until the Cu concn. in the soln. was constant. The plates were then removed, rinsed clean, and reweighed. No Ni ions were detected in the spent etching soln., and screening electron microscopy of the etched plates' surface showed that no corrosive action of the soln.  on the Ni had taken place.
