Title: Production of pentaerythrithiol
IPC: C07C321/04
Filed: 1992-04-02
Abstract: PURPOSE:To obtain the subject compound in high field by reaction of a pentaerythritol tetrahalide with disodium tetrasulfide in an aprotic polar solvent such as N,N-dimethylformamide followed by, if desired, partial desulfurization and reduction with metallic powder. CONSTITUTION:The objective pentaerythrithiol can be obtained by reaction of (A) a pentaerythritol tetrahalide of formula I (X is Cl or Br) with (B) disodium tetrasulfide in an aprotic polar solvent (esp. pref. N,N- dimethylformamide) followed by reduction using metallic powder (e.g. Pt, Pd, Ni, Zn). Or, this pentaerythrithiol can also be obtained by reaction of the compound A with the compound B in an aprotic polar solvent followed by partial desulfurization to produce a compound of formula II, which is then reduced with metallic powder. And, the compound A is made to react with the compound B under heating in an aprotic polar solvent to give a pentaerythritol derivative of formula III (m and n are each 2-4), which is useful as e.g. a monomer for plastics with high refractive index.

Title: Method for measuring concentration by absorption photometer
Inventor: TSUNASAWA YOSHIO
IPC: G01N21/27
Filed: 1987-03-31
Abstract: PURPOSE:To permit automatic concn. measurement with good accuracy by determining the concn. of an original sample by the concn. of the highest reliability which is determined by the predetermined reliability function from the actually measured absorbancy values of the samples as well as the optical path length or dilution rate thereof. CONSTITUTION:The reliability function is previously determined with respect to the absorbancy value and is stored in a memory 9. A sample exchanger 3 is controlled by a CPU 6 to feed the plural samples into a measuring chamber 2 where the absorbancy is measured by using the sample having plural stages of optical path lengths or dilution rates with respect to the same sample. The absorbancy value having the max. reliability is retrieved by the reliability function stored in the memory 9 from the resulted plural absorbancy values and the concn. of the original sample is measured from the optical path length or dilution rate of the sample which gives said absorbancy. An equally good practice is to add the weight determined according to the reliability function to the resulted absorbancy value and to determine the concn. of the original sample by weight averaging.

Title: Production of metallic short fiber
Inventor: SHIYOUJI HISANORI
IPC: D01G1/04
Filed: 1983-05-10
Abstract: PURPOSE:To cut efficiently metallic fibers to short fibers at an optional rate of supply by cutting the melt-spun metallic fibers by means of a rotary cutter consisting of plural pieces of stacked knives. CONSTITUTION:The fibers supplied to a cutter collide against the uppermost knife 1 and are cut by the same. A part of the fibers are further cut shorter while falling downward. The greater part are scattered radially and collide against a perforated plate 4 disposed at the circumference but since the fibers are long, the fibers fall downward without being discharged through the perforated plate and are again cut short by the lower knives 1 then the cut fibers are discharged through the holes of the plate 4. If, however, the fibers are supplied too much, a large amt. of the fibers are bounced to the upper part of the plate 4 and accumulate there, resulting in formation of fiber pills and metallic balls between the knives 1 and the plate 4. Moreover, the knives lose their original cutting quality on account of the heat generated by the collision of the fibers against the knives and the perforated plate, thus giving more tendency to the formation of the metallic balls. Such problem is solved by reducing the size of the upper knives 1.

Title: Vacuum arc treatment method and pre-treatment method
Inventor: TAKEUCHI JUN
IPC: H01H33/02
Filed: 1993-04-08
Abstract: PURPOSE:To control the thickness of a surface reformed layer by feeding oxygen gas at the time of treating an alloy by a vacuum arc. CONSTITUTION:A material 1 to be treated is connected to a negative electrode of a power source 5 and an anode 2 is connected to a positive electrode. An ignition electrode 3 is connected to a high frequency/high voltage power source 7 through a high frequency/high voltage lead 6 and the other side output of the power source 7 is fed to a cathode. Oxygen gas is fed into a vacuum container 4 from an oxygen cylinder 10 through a flow meter 9 and a nozzle 8. Pressure when the oxygen is not fed is adapted as back pressure, and oxygen partial pressure is found by subtracting the back pressure from the pressure inside the container 4. Thickness of a surface reformed layer can be controlled based on the oxygen partial pressure, vacuum arc treating time and scale thickness before the treatment. The thicker the scale before the treatment is, the higher the oxygen partial pressure is, and the longer the treatment time is, the thicker the thickness of the surface reformed layer becomes.
