Title: Removal of pyrogen
Inventor: CHIBA KAZUYOSHI
IPC: A61K9/08
Filed: 1984-05-28
Abstract: PURPOSE:In the removal of pyrogenic substances which dissolve in injection solution or transfusion solutions and develop fever in men and animals, the solution is stirred in the presence of a surfactant with a steroidal skeleton to form a micelle and the micelle is separated from the solution whereby the solution free from pyrogens is obtained.

IPC: F25B1/00
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To alarm abnormality in the composition of a nonazeotropic mixture coolant by detecting variation thereof due to leakage of coolant. SOLUTION: Upon elapsing of a spectfied decision start time after stopping operation, a decision start timer 25 decides that the temperature of coolant is equal to the outer air temperature and transmits a decision start signal. A high pressure sensor 11 detects the pressure of coolant in a coolant circuit and a temperature sensor 13 detects the outer air temperature. A saturation temperature operating means 16 operates the corresponding saturation temperature of coolant based on the information of corresponding saturation temperature for the pressure related to a nonazeotropic mixture coolant R407C stored in a saturation temperature memory means 17. A temperature difference operating means 18 operates the absolute value of difference between the corresponding saturation temperature of coolant and the outer air temperature.  An abnormality decision means 19 makes a decision that the composition of the R407C has varied if the absolute value is larger than a specified decision value and delivers a composition abnormality signal.
