Patent IT-987455-B (IT)
IPC: C07C201/16
Filed: 1973-05-15
Granted: 1975-02-20
Abstract: In a purification process for p-nitrophenol obtained by nitration of phenol, separation of crude nitrophenols, steam distillation to remove o-nitrophenol, and cooling the broth obtained when it contains more than 0.5% sodium bisulphite and is at pH 5.4 to 6.4 to deposit crystals of p-nitrophenol, an improvement consists in stirring the crystals with water at 55 DEG -85 DEG C to give a mixture containing 10-40% excess of p-nitrophenol over the solubility at that temperature, separating the upper layer of p-nitrophenol in water obtained, cooling it to 40 DEG -50 DEG C and separating the layer of water in p-nitrophenol, cooling the latter to below 30 DEG C and collecting the crystals deposited.

Title: Pre strengthened stress relieved steel - by cold working, straightening and rapid heating
IPC: C21D/
Filed: 1975-06-30
Granted: 1979-12-10
Abstract: Stress relieved, pre-strengthened elongated steel workpieces are made by cold working a carbon or low alloy steel workpiece, straightening it by reverse bending and rapidly heating to between 500 degrees F and critical temp. of the steel in 10 minutes. The process is part. applicable to steels contg. 0.1-0.75% C, 0.5-1.5% Mn, 0.01-0.07% P, 0.01-0.5% S, 0.1-5% Cr, 0.-0.5% Mo, 0.1-0.8% Si and balance Fe. The steel is cold worked e.g. by drawing to strengthen the workpieces and is then straightened by passage through rollers e.g. in a Lewis or Medart straightener. The workpiece is then heated to 500-1300 degrees F within 1-300 seconds, preferably by passage of an electric current therethrough.

Title: Continuous and automatic apparatus for control and regulation of the pH value in pumpable products
Inventor: PARO BOZIDAR
IPC: G01N/
Filed: 1990-10-24
Granted: 1994-06-16
Abstract: The continuous and automatic apparatus for control and regulation of the pH value in pumpable products is intended for the chemical, petrochemical, pharmaceutical and food industries. With this type of apparatus it is possible to continuously treat large amounts of product (on a line) with a completely automatic process with very high precision which amounts to +/- 0.02 pH unit. The corrector added to the product passes with it through a static mixer for perfect mixing and then a holding vessel with a coil to provide time for complete electrochemical reaction, whereupon the pH value of the product is measured. If the value departs from the tolerance imposed on the regulator, the product is automatically recycled, which continues until the pH reaches the required value. A metering device controlled by the regulator meters the corrector as a function of pH value, not on the amount of flow. The pH measurement electrode operates in an environment at constant temperature and pressure. The amount and density of the product do not influence the precision of correction. <IMAGE>
