Title: Controller for preinjection of chlorine in water purifying plant
Inventor: TSUKURA HIROSHI
IPC: C02F1/76
Filed: 1989-11-22
Abstract: PURPOSE:To automatically preinject chlorine at an optimum rate by calculating a correction value based on the deviation of the actual amt. of solar radiation from the model amt. or the deviation of the measured value of a residual chlorine content of a treating basin from the desired value and combining the preinjection rates of chlorine obtained at first and second arithmetic units to calculate the preinjection rate of chlorine. CONSTITUTION:The preinjection rate of chlorine D1 based on the expected amt. of solar radiation and the preinjection rate of chlorine D2 based on the measured value of the requisite amt. of chlorine are obtained, and both rates are used as a feedforward factor. Meanwhile, the correction amt.  Db for D1 corresponding to the difference between the expected amt. of solar radiation and the actual amt. and the correction amt.  Da based on the residual chlorine amt. are used as a feedback factor and combined to determine the preinjection rate of chlorine. Consequently, the error due to a control lag, etc., is controlled insofar as possible, the amt. of residual chlorine is fixed, and further a rapid change in the meteorological factor and water quality factor can be coped with. Accordingly, chlorine is preinjected at an optimum rate.

Title: Low release holding pressure check valve
Inventor: CHIYAARUZU DABURIYU DANMAIAA
IPC: F16K15/03
Filed: 1990-11-13
Abstract: PURPOSE: To facilitate designing, manufacturing, installation, and maintenance by arranging a spring between a clapper device and a valve wall, pivoting a pivot point of the clapper by means of the spring, and setting the pivot point in the fixed position in the spring end and the clapper device during opening/ closing of a valve. CONSTITUTION: When an opening force applied to a clapper 32 exceeds a spring closing force, the clapper 32 is released movably from a valve seat 28, and a valve 12 is opened. While the valve 12 is opened, the position of a second shaft 64 is changed with respect to a valve main body 10 but not changed with respect to the clapper 32 and to the adjacent edge of a spring 52. When the clapper 32 pivots around a first shaft 43, an opening angle of the clapper 32 is increased from an angle α77 of about 118 deg. to an angle α77' of about 164 deg.. A closing force applied to the clapper 32 varies from about 87% of a spring force F79 to about 27% of that.  In a valve 12 with a small hold-open force, a minimum value and a maximum valve of the angles α77, 77' are selected so that a closing force in the valve opening position is reduced in comparison with that in the closing position.

Title: Method and apparatus for measuring flying distance of projectile
Inventor: HANSU RISHIERUTO
IPC: G01C22/00
Filed: 1993-11-10
Abstract: PURPOSE: To attain accurate measurements without requiring excessive resolutions for processing by measuring the traveled distance through internal signal processing that is based on the measurement of the initial deceleration of a launched object and on the continuous tracking of gradual deceleration. CONSTITUTION: Initial deceleration, i.e., a value (a0 ) obtained when a shell leaves a gun barrel, is sampled from the deceleration acc measured, and launching speed V0 is calculated from its square. The value V. is integrated to calculate the distance Vo t traveled when the shell is not affected by air resistance. Also, air resistance ratio is calculated through the double integral of the deceleration acc and is combined with the distance V0 to calculate the distance s(t) traveled. In this case, an accelerator (sensor) 1 is placed opposite to and in contact with a fixed support surface 8 that prevents the outward deflection of the beam 2 of the sensor 1 during launching phase, and the sensor 1 moves only in the traveling direction of the shell. Also, an accelerator with a small measuring range which measures only deceleration is used.  Therefore, sufficient distance measuring accuracy is obtained without the need for excessive resolution for signal processing.
