Abstract: Abstract In order to provide radial compression of cylindrical bodies consisting of compressible material, the latter is led axially through a rotationally symmetrical space, which tapers in the transport direction and whose smallest diameter is smaller than that of the body to be compressed, the envelope of the rotationally symmetrical body being generated by roller shaped bodies which rotate in the same direction and cross the axis of rotation of the space at an angle of between 5 and 45° but do not intersect it.  During the passage, the body performs a helical movement relative to the envelope of the rota-tionally symmetrical space and is compressed in the process, the compression being made permanent by wrapping at the narrowest point of the space. Figure 1 is suggested as an illustration.

Granted: 1988-01-05
Abstract: ABSTRACT PROGRESSIVE SCAN TELEVISION APPARATUS      Phase detectors (202,204) in a progressively scanned television receiver measure the phase of the receiver video speed-up memory read (8fsc) and write (4fsc)  clocks with respect to the  double line-rate horizontal sweep signal (FB) of the display.  Delay means (34,36) are provided for delaying the video signal recovered from the memory (30,32) as a function of the difference (224) between the read and write clock phase measurements each time the memory is read.  The delay is effective for minimizing visible-artifacts which otherwise may tend to occur when displaying "non-standard" video signals wherein the ratio of the color-subcarrier frequency to the line-frequency of the incoming video signal differs from a given broadcasting standard.

Abstract: IMMUNOGENIC HAV PEPTIDES            ABSTRACT OF THE DISCLOSURE        Synthetic peptides, containing amino acid residues 15 to 21, 75-80 and 101-107 of the hepatitis A virus (HAV) VP1 structural protein sequence, was prepared and chemically conjugated to a protein carrier molecule.  The peptide-carrier conjugate, when inoculated into test animals, gives rise to a specific anti-peptide IgG antibody response.  These anti-peptide antibodies bind directly to intact hepatitis A virions, bind to purified and denatured VP1, compete with polyspecific antibody derived from human HAV immune sera, and are capable of neutralizing the infectivity of the virus. The peptide is useful as a synthetic subunit immunogen that stimulates an immune response against HAV.
