Title: Method of and apparatus for the magnetic separation of materials
IPC: B03C1/10
Filed: 1923-05-29
Abstract: 220,100. Rushen, P. C., (Krupp Grusonwerk Akt.-Ges., F.). May 29, 1923. Magnetic separators.-In a magnetic separator of the drum or roller type, the magnetic material separated in the annular magnetic field is taken off, thrown off, or guided from the drum and is then led to another point of the same annular field for subsequent separation. The annular field is formed .by a magnetic system 20 formed of two circular disc poles provided on their peripheries with notches 25, 26 producing separating zones 23, 24, the system 20 being surrounded by a drum 19 mounted on the rotary shaft 18. The material is delivered by a shoot 27 over a deflector 28 to the drum 19, the non- magnetic material either falling direct into a receptacle 30 or being directed by a second deflector 29 against the drum 19, as shown. The magnetic material carried by the drum is thrown off, at the weak zone 25, against a baffle plate 31 provided with a part 33 which directs it against the surface of the drum 19. The, non-magnetic material may be allowed to fall into a receptacle or be directed by a baffle 33 against the drum again. In a modification, the magnetic material, at the first point of separation, is guided off the drum and subsequently fed again to the drum as before. In a second modification, the material before being fed to the drum is sifted by a screen, the fine and coarse particles being fed separately to the same drum, the non-magnetic material separated from the coarse particles being received by a separate shoot, and the fine and coarse magnetic material being mixed on the drum. The magnetic material may be removed from the drum by jets of air or water.

Title: Improvements in the preparation of 3-acyloxy-bisnor-cholanic acids
IPC: C07J75/00
Filed: 1940-09-19
Abstract: 544,051. 3-Acyloxy-bisnorcholanic acid. BERGMAN, E. Sept. 19, 1940, No. 14368. [Class 2 (iii)] 3-Acyloxy-bisnorcholanic acid is prepared from acyl lithocholic acid by forming the acid halide, brominating and treating the α-bromo acid thus produced with an acid binding agent to withdraw hydrobromic acid to form the corresponding α-#-unsaturated acid. This is then oxidized to form the required 3-acyloxybisnorcholanic acid. In an example lithocholic acid prepared by the chromic acid oxidation of the benzoyl derivative of methyl desoycholate is converted into acetyl derivative, treated with thionyl chloride to form the corresponding acid chloride, brominated with the theoretical amount of bromine in the presence of red phosphorus, and the bromine removed with pyridine to form the α-#-unsaturated acid. Chromic acid oxidation of this unsaturated acid in glacial acetic acid solution yields the required 3-acetyl-bisnorlithocholic acid.
