IPC: C02F3/02
Filed: 1985-01-25
Abstract: PURPOSE:To excellently perform the injection of chemicals, by setting the objective turbidity of biologically oxidized treated water and making the injection amount of chemicals constant in the sedimentation basin of a water purification plant. CONSTITUTION:In a biological oxidizing treatment tank control apparatus 19, objective turbidity of treated water is set by a treated water objective turbidity setting device 14 with due regard to the removal effect of the org. substance and nitrogen in inflow raw water for the purpose of the security of turbidity necessary for the formation of floc in the sedimentation basin of a water purification tank. The turbidity removal ratio of a biological oxidizing treatment tank 1 is set by the turbidity removal ratio setting device 12 of the biological oxidizing treatment tank 1. The turbidity of raw water flowed into the biological oxidizing treatment tank 1 is measured by an inflow raw water turbidity meter 7 and inputted to a turbidity removal ratio operation circuit 15 which, in turn, performs the temp. correction of a turbidity removal ratio. The number of the biological oxidizing treatment tanks are calculated and controlled by the tolerant inflow amount of the biological oxidizing treatment tank 1 and the turbidity removal ratio thereof.

Title: Liquid transfer device
Inventor: TOMITA TAKEHIKO
IPC: B01J4/00
Filed: 1978-02-02
Abstract: PURPOSE: When liquid drawn from a plurality of reservoirs is supplied through a single pipe, the flow rate of 100% opened least flowable valve is selected as the minimum flow and the deflection from this valve is detected. Each adjusting valve is controlled to the minimum flow rate to make each flow uniform.  
     CONSTITUTION: From the final dirt reservoirs 10 a , b , c  dirty water is collected through  each line 11 a , b , c  into a single line 12, then transmitted by the pump 13, 14 to air  exposure baths etc. Flow detector 15 a , b , c  of each line detects each flow rate and  sends this detection to the raw selector 21 through the adjuster 17 a , b , c  and the switch  19 a , b , c . Each adjuster issues signal to instruct the degree of valve opening of the  adjust valve 16 a , b , c . Also, this signal enters the valve-open degree judger 18 a , b , c  to  check the degree of open for 100%. If it is not 100%, the switch 19 a , b , c  is changed to  connect the 100% signal generator 20 to the raw selector 21. For 100% open valve,  the switch is left as it is and the flow rate of the detector 15 a , b , c  is entered into the  low selector 21.

Abstract: The invention provides a process for pre-polymerizing olefin polymerization catalysts and a process for increasing the efficiency of pre-polymerized olefin polymerization catalysts. In one process of this invention an olefin monomer is added to a fluid carrier stream containing an olefin polymerization catalyst. The carrier stream containing the monomer and the catalyst is passed through an elongated tubular reactor at a flow rate sufficient to provide a residence time in the tubular reactor of less than 1 minute and under temperature conditions to pre-polymerize the catalyst within the tubular reactor without plugging of the reactor. In another process of this invention a pre-polymerized catalyst is contacted with a cocatalyst or a mixture of cocatalyst and an electron donor prior to introducing the catalyst into a polymerization reaction zone. <IMAGE>

Even in this case, a mixing device 15 has a sufficient capacity, so that the high pressure gas and the liquid refrigerant are rapidly and completely mixed to each other in the mixing device 15 and then a transient phenomenon may not occur.

Title: Peripheral structure of inclined duct hole in radiation shielding wall
Inventor: YAMAJI AKIO
IPC: G21F3/00
Filed: 1988-01-25
Abstract: PURPOSE:To intend an improvement of a radiation shielding ability, by placing a compensating shielding made of a material having a better shielding property than a concrete, as a tube of a duct hole and, by extending the tube from both opening ends of the duct hole. CONSTITUTION:A duct hole 11 is formed through a shielding wall 10 and a duct tube 12 made of a material having a better shielding property than a concrete, is placed protrudently from both opening ends. In this situation, the duct hole 11 is placed so that its center axis may incline against surfaces of the shielding wall 10. Therewith, among vertically incident radiations to the shielding wall 10, radiations which permeate through the duct hole 11, are attenuated by permeating through the duct tube 12 which have a property of compensating shielding when they come into and go out of the duct hole 11. Consequently, with rather simple structure, a shielding property can be improved.
