Abstract: PURPOSE:To enable an online measurement with a continuous and quick operation, by measuring a dielectric constant of a liquid to be measured before and after cleaning when the liquid being measured is cleaned by an alkaline or neutral cleaning solution to calculate changes in the dielectric constant before and after the cleaning. CONSTITUTION:A liquid to be measured is introduced between pole plates 2a and 2b of a first dielectric constant measuring cell 2 with piping 1 to measure a dielectric constant with a capacitance measuring device 3. The liquid being measured further flows into a counterflow contactor 5 through a piping 4 and is stirred up together with an alkaline or neutral water phase to be injected at an upper inflow port 5b by an agitator 5a. The water phase as heavy liquid is discharged at a lower outflow port 5c while the liquid being measured as light liquid flows over continuously at an upper outflow port 5d and flows into a second dielectric constant measuring cell 7 passing through a piping 6 to measure a dielectric constant with a capacitance measuring device 8 likewise. The dielectric constants measured with the devices 3 and 8 are inputted into a calculator 10 to obtain a difference between both values and the results are compared with a calibration curve of concentration of nitric acid vs dielectric constant to calculate the desired concentration.

Filed: 1990-06-26
Abstract: PURPOSE:To short-circuit a main circuit of each pole to a short-circuiting circuit when excess current runs in the main circuit in order to make recovery work easy after a trouble happens by installing a movable conductor in the main circuit of each pole in series and at the same time forming a contact for short- circuiting responding to the movable conductor of each pole. CONSTITUTION:When excess current runs in a main circuit 34 of each pole because of short-circuit trouble, etc., a drawing out apparatus 19 works by an instant drawing out coil 21 and parts a movable contactor 15 from a fixed contactor 14 to start shutting work.

Title: Vulcanizing process in dome type-vulcanizing machine
Inventor: TAKAHAMA ITSUO
IPC: B29L30/00
Filed: 1988-07-05
Abstract: PURPOSE:To heighten productivity and to minimize energy loss by a method in which the vulcanizing steam of high temperature and high pressure is continuously ejected upward from the lower part of a steam box, and the steam is caused to collide with ceiling of an upper dome and the connecting shaft connecting an upper vulcanizing mold to the upper dome. CONSTITUTION:The vulcanizing machine of dome type has the cylindrical lower dome 3 fixed on a horizontal heat insulating plate 2, and a lower vulcanizing mold 5 is fitted onto a lower fitting plate 4. An upper dome 7 is connected to an upper vulcanizing mold 11 by the connecting shaft 9 with relatively large diameter. The vulcanizing steam of high temperature and high pressure is continuously ejected upward from an ejecting port 28 into a steam box 14 without stop until the temperature and the pressure inside of said box reach the temperature and the pressure sufficient for vulcanizing. Since the steam is decelerated by the collision with the ceiling 8 of the upper dome 7 and the connecting shaft 9, the steam for vulcanization is not almost mixed with air. Consequently, the volume of the steam for vulcanization to be discharged outside, becomes small remarkably.
