  • Patent number: 5677129
    Abstract: A method for preparing probes, as well as several probes for use in qualitative or quantitative hybridization assays are disclosed. The method comprises constructing an oligonucleotide that is sufficiently complementary to hybridize to a region of rRNA selected to be unique to a non-viral organism or group of non-viral organisms sought to-be detected, said region of rRNA being selected by comparing one or more variable region rRNA sequences of said non-viral organism or group of non-viral organisms with one or more variable region rRNA sequences from one or more non-viral organisms sought to be distinguished. Hybridization assay probes for Mycobacterium avium, Mycobacterium intracellulare, the Mycobacterium tuberculosis-complex bacteria, Mycoplasma pneumoniae, Legionella, Salmonella, Chlamydia trachomatis, Campylobacter, Proteus mirabilis, Enterococcus, Enterobacter cloacae, E. coli, Pseudomonas group I, Neisseria gonorrhoeae, bacteria, and fungi also are disclosed.

  • Patent number: 5352558
    Abstract: A device for increasing the solids content of an image formed from liquid developer comprising a belt which is comprised of an absorption material containing small pores to absorb dispersant from a dispersant laden image and a pair of rollers bearing the belt wherein the belt on one of the rollers contacts a dispersant laden image bearing portion of an image carrying member such as a photoreceptor drum or an intermediate sheet.

  • Patent number: 5233396
    Abstract: A toner image is transferred from an electrostatographic imaging member to an image receiving substrate. A biased transfer member in the form of a roller or a belt forms a nip with the imaging member. A compliant intermediate transport member passes through the nip for receiving a toner image from the imaging member. The intermediate transport member is preferably semiconductive, and self-discharges in less than one second. In a preferred process for transferring the toner image to a conductive conformable intermediate, both the intermediate transport member and the biased transfer roller are conductive.
