Title: Swine fever immunogenic agents and vaccines - prepd. by inactivation of pathogenic virus with an alkylating agent pref. glycidaldehyde without denaturation of the virus
IPC: A61K39/187
Filed: 1977-04-06
Abstract: Prepn. of immunogenic agents against swine fever and vaccines containing them, comprises inactivation of cultures of swin fever pathogenic virus using an alkylating agent. The nature and concn. of the agent are chosen so that the kinetics of the inactivation reaction can be controlled and inactivation may be completed without causing denaturation of the virus the inactivation reaction is then stopped by neutralising the excess alkylating agent. The use of an inactivated virus avoids the risks of development of modified strains of the virus, which may occur when living virus vaccines are used. The process leads to an effective vaccine, free from all pathogenic risk and having well defined, reproducible characteristics. The pref. virus used is known as A-19 isolated by Laboratoire Central de Recherches Veterinaires at Maisons-Alfort.

Closed loop control is provided because the relevant factors of line operation are measured, the analogue measurements converted to digital values and compared with the stored values to produce a control signal which has the effect of reducing the differences between a desired and measured line condition as represented by the digital values compared. Closed loop control is also provided for control of the line to produce desired capacitance or diameter values in the coated wire. Whichever of capacitance or diameter is used as the basis for line control is measured and provided as a digital value to the control. This digital value is compared to a stored digital value representative of the desired capacitance or diameter. The results of the comparison is used to update the stored digital value for an operating condition of the line so that the parameter is altered to provide an operating condition which brings the capacitance or diameter closer to the desired value.
