Title: Myxomatosis vaccine - by serial passage in chick embryo then in rabbit kidney cells
IPC: A61K39/275
Filed: 1970-05-15
Abstract: Prepn. of vaccine against myxomatosis in which a cell culture is inoculated with an attenuated myxomatosis virus obtd. by serial passage on the chorioallantoic membrane of chick embryos, then culture on rabbit kidney cells until virulence to the rabbit has completely disappeared, finally incubating the culture medium and collecting the viral suspension.

Title: Small vehicle drive system with turbine and batteries - pre-heats fuel air mixture to reduce exhaust pollution
IPC: F02C3/04
Filed: 1973-07-04
Abstract: The compressor (1) is driven by an electric motor (2) through the gear train (3).
