Title: Temperature controller for centrifugal machine
Inventor: NAGATA AKIO
IPC: B04B15/02
Filed: 1986-05-23
Abstract: PURPOSE:To control the keeping temp. of a rotor with high precision and to carry out centrifugal separation with high accuracy by cutting off the power supply to a heater when the temp. of an evaporator on the outer periphery of the rotor of the centrifugal machine reaches a specified value against the set temp. of the rotor. CONSTITUTION:A temp. detector 13 is fixed to the evaporator 7 in the temp. controller of the centrifugal machine for separating and purifying a biological substance while keeping the substance at low temp. When the temp. of the temp. detector 13 reaches a set temp., a heater control signal is inputted, and the power supply to the heater is cut off. Consequently, the keeping temp. of the rotor 4 can be controlled with higher precision. As a result, centrifugal separation as well can be performed with high accuracy.

Abstract: PURPOSE:To simplify constitution by providing a first electromagnetic valve exhausting a wheel cylinder pressure and a second electromagnetic valve bypassing a reducing valve to apply a constant pressure reduced by the reducing valve to rear wheels after exhausting a braking pressure of the rear wheels. CONSTITUTION:A first electromagnetic valve 16 is connected through a proportional valve 13 to a master cylinder 10, and serves to exhaust a braking pressure into a reservoir 15 upon locking of wheels. A second electromagnetic valve 17 is arranged at the rear of the first electromagnetic valve 16 and normally bypasses a reducing valve 18.

Abstract: PURPOSE:To almost perfectly remove a cyanide compound in a safe and simple manner, by bringing air containing uncondensed hydrogen cyanide exhausted from a reaction container into contact with an oxidizing catalyst at reaction temp. of 250 deg.C or more. CONSTITUTION:A waste solution to be treated is poured in a reaction container 1 and acid sodium hexametaphosphate is added to said waste solution to adjust the pH thereof to 2 or less and the pH adjuted waste solution is sucked by a pump 7 while the reaction container 1 is heated by a heater 5.
