Title: Process of and apparatus for preparing dinitrogen pentoxide
Inventor: BAGG GREVILLE EUAN GORDON
IPC: C01B21/20
Filed: 1997-06-26
Abstract: PCT No. PCT/GB91/01250 Sec. 371 Date Apr. 17, 1992 Sec. 102(e) Date Apr. 17, 1992 PCT Filed Jul. 25, 1991 PCT Pub. No. WO92/02452 PCT Pub. Date Feb. 20, 1992.Process for producing dinitrogen pentoxide (N2O5) consists of reacting a solution of dinitrogen tetroxide (N2O4) in a volatile organic solvent, with a stream of an ozone-containing carrier gas. N2O5 produced by reaction between the N2O4 and ozone is transferred into the gas stream, and is thereafter condensed out of the gas stream by contact with further inert organic solvent. The latent heat of formation of N2O5 is absorbed by the heat of vaporization of the solvent, so limiting increases in reaction temperature and suppressing the dissociation of the N2O5. In a preferred embodiment the reaction and absorption steps are performed in separate columns having organic solvent recalculating continuously through each with carrier gas flowing continuously from the reaction column to the absorption column.

Title: Production of color filter
Inventor: AKIYAMA KATSUHIKO
IPC: G02B5/20
Filed: 1982-01-08
Abstract: PURPOSE:To obtain a color filter which is free from degradation in optical characteristics such as decrease in transparency by forming the 1st, and 2nd org. filter patterns on a substrate, and hardening the surface layer of the 1st patterns then forming the 2nd patterns. CONSTITUTION:A layer 12 of a photosensitive material to be dyed consisting of, for example, a mixture of gelatin and ammonium dichromate is coated on a substrate 11. The layer is subjected to selective exposure corresponding to the patterns of color filters of the 1st color, for example, green and is then developed to form patterns. This substrate is immersed in a dyeing soln. for green, whereby filter patterns G of green are formed. The substrate is subjected to a fixing treatment for green, whereby a hardened layer is formed on the surface thereof. If the similar treatments are performed thereon with red and blue as well, color filters 13 juxtaposed with green, red and blue roughly within the same plane are obtained. Thus, the color filters free from degradation in optical characteristics such as decrease in transparency are obtained.

Abstract: PURPOSE: To improve size distribution of stuff cast into a furnace by dividing a rotary chute of a casting device at the top of a bell-less furnace into a main body and a tip part so as to allow its free slanting motion.  
     CONSTITUTION: A rotary chute 6 is divided into a main body 6A and a tip part 7A which is made vertically rotatable with respect to the body 6A by means of a pin 11. Further, a fixed point 14 provided on a bracket 13 rotating around a furnace center 12, a pin 15 provided on the side of the main body 6A and a pin 16 provided on the side of the tip part 7A are connected by means of a link mechanism. When the chute 6 is put into slanting motion, the tip part 7A can change an angle α of slanting motion in accordance with an angle θ of slanting motion of the main body 6A. In case the angle θ is wide, the tip part 7A stretches instead of making a slanting motion so that raw material may be cast closely to an interior wall of a furnace. In case the angle θ is narrow, the tip part 7A declines so that expansion of width of a locus for the raw material dropping may be prevented.

IPC: G01B7/00
Filed: 1981-01-10
Abstract: PURPOSE:To perform a simultaneous inspection of a trouble part when an induction heating of a material to be heated is conducted, by a method wherein an AC power is applied to a parallel circuit in which a capacitor is connected in parallel to a heating coil surrounding the material to be heated to discriminate the resonance frequency of the parallel circuit. CONSTITUTION:A frequency of a parallel circuit 4 or a frequency of an AC power from an AC power source 5 is detected by a frequency detecting circuit 13. In case a normal part 1a of an electroseamed steel pipe being of a material 1 to be heated is positioned in a coil 2, a frequency f1 of an AC power applied to the parallel circuit 4 is, for example, 1-10KHz, and in case an abnormal part 1b such as cracks exists in the material to be heated, the frequency of the parallel circuit 4 is reduced to, for exmaple, 10% lower frequency f2. Thus, if a comparision circuit 16 becomes below a frequency L corresponding to a reference voltage level set by a reference level setting means 15, an indicator 17 indicates the presence of the abnormal part 1b in the material 1 to be heated.
