  • Patent number: 11752566
    Abstract: A steel workpiece includes an alloy substrate comprising iron, about 1.4 to about 2.0 weight percent aluminum, and about 0 to about 1.0 weight percent silicon. The steel workpiece further includes a coating comprising zinc. A method of spot welding a workpiece stack-up that includes a pair of the steel workpieces includes providing the stack-up, contacting first and second electrodes to the steel workpieces, passing an electrical current through the stack-up, forming a weld nugget from molten mixing of the alloy substrates of the pair of steel workpieces, forming a boundary layer between the coating and the alloy substrate from dispersion of the coating into the alloy substrate and reaction of the zinc with the aluminum and the silicon to prevent molten mixing of the coating within the alloy substrate, and ceasing passage of the electrical current.

  • Patent number: 6483688
    Abstract: A circuit for controlling a valve assembly in applications where electrical isolation of the two control signal supply lines is required to prevent damage of control circuits caused by a reverse polarity feedback signal or other transient signal. The circuit includes a solenoid having a coil. The coil has a first end and a second end. The circuit also includes a first switching circuit electrically connected to the first and second ends of the coil to allow current to pass therethrough in a first direction to move a permanent magnet against a pushpin a first axial direction. The circuit further includes a second switching circuit electrically connected to the first and second ends of the coil to allow a current to pass therethrough in a second direction to move the permanent magnet away from the pushpin in a second axial direction. Further, when either switching circuit is allowing current to flow through the coil, it electrically isolates one negative control source from the other.

  • Patent number: 6129115
    Abstract: A self-latching solenoid valve assembly including a valve body having a pressurized air supply inlet port for communicating with a source of pressurized air and at least one cylinder port. A valve member is supported in the valve body so as to be movable between predetermined positions to selectively direct pressurized air from the inlet port to at least one cylinder port. A biasing member is employed to move the valve member in one direction and a solenoid assembly is used to move the valve member in an opposite direction. The solenoid assembly includes a housing with a solenoid coil supported therein and a fixed ferromagnetic pole piece having a passage extending therethrough with a pushpin movably supported in the passage. A ferromagnetic latch is also supported by the housing and spaced from the pole piece. A permanent magnet is disposed between the latch and the pole piece.

  • Patent number: 5908780
    Abstract: Infection of human fibroblast cells with human cytomegalovirus (HCMV) causes down-regulation of cell surface expression of MHC class I. A recombinant mutant HCMV which fails to down-regulate class I heavy chain expression is described. A method of controlling down-regulation of MHC class I expression in a cytomegalovirus infected cell, a pharmaceutical composition, a vaccine composition,a method of preventing or reducing susceptibility to acute cytomegalovirus in an individual, and a virus based gene therapy vector are also described.

  • Patent number: 5906935
    Abstract: Infection of human fibroblast cells with human cytomegalovirus (HCMV) causes down regulation of cell surface expression of MHC class I. The present invention is directed to a mutant with a 9-kb deletion in the S component of the HCMV genome (including open reading frames IRS1-US9 and US11) which failed to down regulate class I heavy chains. By examining the phenotypes of mutants with smaller deletions with this portion of the HCMV genome, a 7-kb region containing at least 9 open reading frames was shown to contain the genes required for reduction in heavy chain expression. Furthermore, it was determined that two subregions (A and B) of the 7-kb region each contained genes which were sufficient to cause heavy chain down regulation. In subregion B, the US11 gene product is involved. It encodes a endoglycosidase H-sensitive glycoprotein which is intracytoplasmic, similar to the adenovirus type 2 E3-19K glycoprotein which inhibits surface expression of class I heavy chains.

  • Patent number: 5877004
    Abstract: This invention relates to a method for identifying non-essential genes of the human cytomegalovirus (HCMV) genome through the insertion of a .beta.-glucuronidase marker gene into a specified HCMV gene, such that, if the product of the HCMV gene is not expressed, the gene is identified as non-essential for replication of HCMV. This invention also relates to a method of screening for compounds which inhibit HCMV by the insertion of the .beta.-glucuronidase marker gene into a HCMV gene, such that the enzyme marker is expressed and cleaves a conjugate chemical substrate in an assay system to yield a detectable fluorescing product or to result in a color change. This invention further provides the gene responsible in HCMV early cytopathic effect.
