  • Patent number: 5980034
    Abstract: An anti-clogging nozzle system for a continuous jet ink jet printer is disclosed. A printing nozzle has both an ink inlet and an ink outlet permitting constant ink flow behind the nozzle orifice during printing. A pressure sensor monitors the ink flow and signals clogs to an automatic unclogging system. The unclogging system includes a control circuit to initiate an unclogging operating cycle when necessary. One of two unclogging modes is employed, both of which require the control system to operate an unclogging valve to vary pressure in the ink return line.

  • Patent number: 5763198
    Abstract: The invention is directed to rapid and quantitative assay systems for screening test compounds for their ability to modulate tyrosine kinase or phosphatase activities involved in signal transduction by determining the tyrosine phosphorylation state of a protein substrate using an anti-phosphotyrosine antibody and an antibody specific for the protein substrate. These assays may be practiced in a whole cell or cell-free system. The assays can be used to identify test compounds for use in therapeutic applications to disease processes in which tyrosine kinase or phosphatase activity in a signal transduction pathway contributes to a pathological process.

  • Patent number: 5646663
    Abstract: An apparatus and method for producing a stream of ink drops in a continuous ink jet printer having a maximum allowable number of fast satellite drops. An ink, which may be a hot-melt ink in its liquid phase, is pressurized for continuous flow to a nozzle and a rectangular or triangular waveform is generated at a fixed frequency. The waveform is applied to a transducer coupled to the nozzle such that nozzle vibrates and the ink flow is perturbed and discharged from the nozzle as primary drops with satellite drops formed therewith. The harmonic content of the rectangular or triangular waveform is adjusted until the desired number of fast satellite drops suitable for desired image formation are formed in the stream of primary drops. In a preferred embodiment, the desired number of fast satellites is a maximum of three.
