  • Publication number: 20240175462
    Abstract: A steering shaft assembly includes a shaft having a first end region including a nose, a male spline region coupleable with a female spline region of a clamp yoke, a ring flag seat adjacent said nose, and a first ring flag locating feature between said ring flag seat and said male spline region. The steering shaft assembly also includes a ring flag having an annular band seated on said ring flag seat, a flag extending axially from said annular band in a first direction beyond said first end and radially outwardly from said annular band, and a second ring flag locating feature extending axially from said annular band in a second direction opposite said first direction, said second ring flag locating feature interacting with said first ring flag locating feature to orient said ring flag in a predetermined rotational orientation relative to said shaft.

  • Patent number: 4403041
    Abstract: A novel method of diagnosis of atherosclerosis comprises comparing the migration of endothelial cells or of cells of endothelium-like morphology in vitro, in the presence of serum from the person being examined, with the migration of identical cells in the presence of serum from healthy persons or of other standard sera, and interpreting a reduced migration in the presence of serum of the person being examined as being an indication of the possible existance of atherosclerosis in this person. The cell migration is measured for example on monolayer cell cultures of pig aorta endothelial cells or of Balb/c 3T3-A31 cells, in which cultures a portion of the cellular layer has been removed. An outfit for carrying out the method contains the materials and devices necessary for the purpose.
