Title: Purificn. of wet-process phosphoric acid - by dehydrative extn. in a water-miscible organic solvent
Inventor: WOJTECH BERNHARD DIPL CHEM DR
IPC: C01B25/46
Filed: 1974-07-06
Abstract: The purificn. of H3PO4 (esp. wet-process H3PO4) is carried out by (a) mixing the H3PO4 (or an aq. soln. thereof) in a vol. ratio of 1:0.3-30 (pref. 1:1-4) with a water-miscible organic solvent having a b. pt. above that of H2O or the H2O/solvent azeotropic mixt.; (b) heating the resulting soln. at a temp. between the b. pt. of H2O (or the azeotropic mixt.) and the b. pt. of the solvent until all or most of the uncombined H2O has been removed; and (c) sepg. the H3PO4 soln. from the residue. The process avoids the loss of selective solvent power associated with high H2O concns. in the extn. solvent, thus avoiding pre-concn. of the crude H3PO4, predehydration of the solvent, etc. The process can be effected in a single step and gives high P2O5 yields.
Patent DE-2435472-A1 (DE)
Title: Continuous sampling of liquids flowing in pipes - using pressure difference between inlet and outlet of bent pipe piece
Inventor: KRUEGER KLAUS
IPC: G01N1/20
Filed: 1974-07-24
Abstract: The pressure difference between the inlet and outlet positions in a piece of bent pipe makes possible continuous sample collections and their return through two radial connecting pieces. No additional flow resistance is introduced by a pipe narrowing. The two connecting pieces are formed so that one points outward, and the other inward. Their clear sections depend on the required sample volume. The device is suitable for both liquids and gasses. It makes no difference in which direction the medium flows since the sampling procedure remains the same and so extra resistance is introduced in either direction.

Patent DE-2500578-A1 (DE)
Title: Introducing magnesium into molten cast iron - in form of briquettes made from magnesium and iron turnings to slow down heating
Inventor: HOELLER HORST
IPC: C21C1/10
Filed: 1975-01-09
Abstract: Introduction of magnesium into molten cast iron by immersing into the melt briquettes containing Mg with addition of Fe to prevent too rapid heating of Mg is improved in that the briquettes are prepd by compressing together cast iron turning with magnesium alloy turnings (wastes from the machining of magnesium alloys, e.g. Mg-Al), the content of the latter being 5-50 wt.% (pref. 10-20 wt.%) w.r.t. the briquettes. Magnesium promotes the formation of graphite spherules improving the ductility of cast iron. The introduction of Mg protected with Fe against too rapid heating prevents evaporisation of Mg (b. pt. = 1105 degrees C). This method is much less expensive than the use of Ni or Cu as a vehicle for Mg (in the form of Ni2 Mg or Cu2Mg). Al if present in the Mg alloy is not harmful.

Title: Workpiece polishing machine using abrasive paper strip - with roll drive motor speed as function of dia and paper speed
Inventor: ERNST JUN PAUL
IPC: B24B21/00
Filed: 1975-01-24
Abstract: The machine has a transporter for the workpiece and a contact component thrusting against a strip of abrasive paper. This is of the same width as the workpiece, and is moved via the contact component from a first to a second roll and then back again. The strip travels at a speed which is a function of the cutting speed necessary during abrasion. Where an abrasive cylinder is used as the contact component, this rotates at constant speed. The speeds of the motors driving the abrasive paper rolls are set as a function of the roll diameters and the paper speed. A slight braking effect is exerted on the roller from which the paper strip is unwound.
