摘要： A method for measuring the real hot-spot temperature in an electric apparatus containing an oil, such as an electric power transformer. The electric apparatus is operated under predetermined and modifiable operating conditions. This method comprises the use of one or several chemical compounds or tracers present and soluble in the oil. Each tracer may transform, at a given temperature, in order to form a residue, such as a soluble gas. From the presence of the residue in the oil, the operator will be able to determine under which predetermined operating condition the hot-spot has been reached and to deduce the hot-spot for a given condition. Among different used compounds, there are diazoic compounds, carbonyl metals, colorants, pigments, liquid crystals and albumins. The method also allows to check the quality of the apparatus on the market and to estimate its life span.

摘要： PROBLEM TO BE SOLVED: To provide an automatic tasting system capable of making total testing time extremely short or shortest in the case of transferring petroleum product samples to a plurality of testing devices by self-propelled robots and testing them. SOLUTION: This automatic testing system includes self-propelled robots 13A and 13B and a plurality of testing devices D to perform a plurality of common or not common tests on a plurality of petroleum products. One or a plurality of petroleum product samples to be set at each testing device D are collectively transferred to each of the testing devices D by the self-propelled robots 13A and 13B. In the testing devices D, the tests are sequentially performed on the petroleum product samples transferred by the self-propelled robots 13A and 13B. Each petroleum product sample is transferred by the self- propelled robots 13A and 13B according to a predetermined schedule unit SU so that the total testing time on the plurality of petroleum products may be shortened.

摘要： PURPOSE: To automate the measurement of an ignition point and to obtain high accuracy and good reproducibillty by relatively simple constitution by filling a closed measuring chamber with a substance to be inspected and measuring internal pressure generated after ignition to confirm ignition. CONSTITUTION: A measuring laboratory dish 1 is filled with a predetermined amt. of a substance to be measured to be bonded to a lid 2 under pressure manually or automatically by a pressure bonding device 8. The lid 2 is heated to temp. lower than an estimated ignition point to wait the temp. rise of the measuring laboratory dish 1 accompanied by the temp. contact of the measuring laboratory dish 1 and the lid 2. Temp. is monitored and measured by temp. sensors 5, 6. After the temp. of the measuring laboratory disk 1 is made equal to that of the lid 2, the substance to be measured is ignited through an electrode 3 at a definite temp. interval while the temp. of the lid 2 is slowly raised. A rise in pressure immediately after the ignition of the substance to be measured is measured by a piezoelectric resistance type pressure signal generator 4 to set the temp. of the substance to be measured at a time of a rise in pressure to an ignition point.

摘要： PURPOSE:To make it possible to perform on-line measurement of a flash point simply and positively and to control the flash point efficiently, by measuring the flash point from a signal which is obtained by dividing the difference between gas concentrations at two points at specified temperatures by the difference between the specified temperatures at the two points. CONSTITUTION:Specified temperature setting coolers 4 and 5 are provided on a kerosene sample line 10, which is branched from a kerosene distillating line 8. Kerosene streams, which are set at specified temperatures with the coolers 4 and 5, are sent into vapor phase sample pots 6 and 7. Gases, which are evolved in the pots 6 and 7, are sent to gas quantity detectors 13 and 14 together with air streams. The detector 13 and 14 detect gas concentrations. The data are inputted into an arithmetic unit 15. Said detection of the concentrations is continuously performed on line. The arithmetic unit 15 receives the data signals of the gas concentrations, which are sent from the detectors 13 and 14. A signal is obtained by dividing the difference in gas concentrations of both gases by the difference between the preset temperatures. The signal is operated, and a signal corresponding to the flash point of the kerosene in a kerosene striper 2 is outputted. The output signal is further sent to a steam control valve 16, and the flash point of the kerosene is controlled.

摘要： PURPOSE:To measure accurately and simply a flash time by detecting variations in pressure, sound or light caused by a flashing point measuring apparatus. CONSTITUTION:A liquid sample 3 is introduced to a main body 1 of the flash point measuring apparatus, and heated by a heater 9 to vaporize the liquid 3 into discharging space 13. Air is supplied to the space 13 from an air supplying apparatus 20 through the liquid 3, the discharge is performed by spark discharging electrodes 14 to cause the flash and a pressure variation in the space 13 caused by the flash is detected by a pressure sensor 18 through a waveguide 19. The flash time can be detected by detecting the variation in sound or light other than the pressure variation. By constituting in such a way, the flash point of petroleum or the like can be detected accurately and simply.
