Title: Continuous emulsion polymerization
Inventor: UEMURA TAKEMASA
IPC: C08F2/00
Filed: 1981-05-22
Abstract: PURPOSE: To prevent formation of agglomeration during polymerization and thereby to make a long-time continuous operation possible, by pre-emulsifying a material monomer by application of ultrasonic waves, supplying the pre- emulsified monomer to a polymerization system and continuously emulsion- polymerizing the monomer.  
     CONSTITUTION: An emulsifier such as an anionic surfactant or a nonionic surfactant is added to an emulsion-polymerizable, water-soluble monomer such as styrene, vinyl acetate or acrylonitrile, and the mixture is emulsified by applying thereto ultrasonic waves. Then, the resulting material monomer emulsion is continuously supplied to a polymerization system agitated, for example, by mechanical means, and the emusion is emulsion-polymerized. This process makes it possible to shorten the induction time of polymerization thereby to heighten the polymerization rate and to prevent formation of agglomerates during polymerization thereby to obtain a polymer with a uniform particle size. Here, this effect is further heightened by agitating the polymerization system by means of ultrasonic vibration.

Patent JP-S4958462-A (JP)
IPC: F23J3/06
Filed: 1973-07-13
Abstract: A process for removing fuel ash from precipitator bottoms circulates water through the bottoms to carry off the ash, then passes the water at least in part through a hydrocyclone separation stage to produce a major overflow fraction of reduced solids content and a minor overflow fraction of increased solids content, and recirculates the water withdrawn from the bottoms less the underflow fraction back through the bottoms at a rate to maintain the solids concentration less than that at which substantial settling out of solids will occur. Preferably, the recirculation is continuous, and the underflow from said hydrocyclone separation stage is subjected to secondary stage hydrocyclone separation from which the underflow may be subjected to tertiary stage solids separation, the overflow from one or both further separation stages being recirculated.

Title: Method of temperature control of fermentation mixture and heat pipe used therein
Inventor: MATSUFUJI MASARU
IPC: A23L11/20
Filed: 1984-04-19
Abstract: PURPOSE:Heat pipes which have electric heaters and heat medium built in are inserted in the fermentation mixture and heated at the start of the fermentation, then the temperature is controlled, e.g., by stopping applying electricity, when cooling is required because of exothermal reaction after the start of fermentation, whereby fermentation product of high quality is obtained. CONSTITUTION:Several heat pipes 10 which have electric heaters 10 and heat medium such as water 18 built in are inserted in the fermentation mixture in the tank 28. When electricity is applied, the heat medium works to heat the pipes 10 uniformly to facilitate warm fermentation. When the temperature in the tank rises over a prescribed level, the electricity is stopped and the heat pipes acts as coolers. Namely, the heat in the fermentation mixture dissipates in the form of latent heat of vaporization through fins 24. Thus, both the peripheral part and the center are kept at a certain temperature range in the tank 28.

Title: Drive pulse width control circuit of printing head
Inventor: KAMITSUBARA KINJI
IPC: B41J2/30
Filed: 1988-03-30
Abstract: PURPOSE:To control a drive pulse width analogously and to always apply constant energy to a printing head without being affected by the variation of the voltage of a power supply, by proper selecting the values of the resistor and condenser of an integrating circuit. CONSTITUTION:A detection circuit 5 issues a signal to a driver circuit 6 in order to drive a printing head at the start time of printing and also issues the same to a power source voltage supply circuit 1 at the same time. The power source voltage supply circuit 1 supplies a current to an integrating circuit 8 on the basis of said signal. When the condenser 3 of the integrating circuit 8 is gradually charged to become a set value, the detection circuit 5 detects this state to stop the signal to both of the driver circuit 8 and the power source voltage supply circuit 1. Thereafter, the charge of the condenser 3 of the integrating circuit 8 is discharged through a discharge circuit 4 to finish one driving. Printing is performed by continuously performing a series of the operations. When the voltage of a power supply is varied, the time before the charge applied to the condenser 3 of the integrating circuit 8 reaches a set value is changed and a drive pulse width is automatically controlled.
