Abstract: The present invention provides recombinant DNA molecules comprising a sequence encoding a transmissible gastroenteritis virus polypeptide selected from the group consisting of M, N and P, host cells transformed by said recombinant DNA molecule sequences, the M, N and P polypeptides. The present invention also provides subunit vaccines for TGEV.

Abstract: A method of printing a succession of images on to an elongate web, in at least two colors, comprises feeding the web past the first and second rotating printing cylinders 10 and 11, the first print cylinder applying a first color and the second print cylinder applying a second color, and periodically interrupting the movement of the web past the print cylinders, the length of the interruptions controlling the repeat distance, and the interruptions of the movement of the web past the second cylinder being controlled in dependence upon the images being produced by the preceding print cylinder. The web may be driven by means of a servo motor such that the extent to which the web moves while the motor accelerates to and/or decelerates from, its normal running speed is accurately predetermined.
