Title: Level converting bus extender with subsystem selection signal decoding enabling connection to microprocessor
Inventor: KHAN SALIM M
IPC: G06F13/40
Filed: 1987-09-24
Granted: 1991-10-29
Abstract: LEVEL CONVERTING BUS EXTENDER WITH SUBSYSTEM SELECTION SIGNAL DECODING ENABLING CONNECTION TO MICROPROCESSOR                   ABSTRACT    The bus extender circuit is a least replaceable unit which interfaces between intermodule subsystems and the microprocessor controller of the system.  The bus extender circuits are structured so that the subsystem modules may be placed in different power zones.  As a result, one subsystem may be powered down without affecting the other subsystems connected to the microprocessor's bus.  In addition, the bus extender circuit converts from Fairchild Advanced Schottky TTL logic to high-speed CMOS logic and vice versa and allows bus interface gate arrays located in each subsystem to interface between the subsystem logic and the microprocessor.  This bus extender circuit design eliminates the need for strapping options or DIP switches for address decoding.

Title: Cdna clone for human tyrosinase
Inventor: KWON BYOUNG S
IPC: C12N15/53
Filed: 1987-10-06
Granted: 1992-01-07
Abstract: ABSTRACT This discovery resulted when a .lambda. gtll cDNA library of normal human melanocytes were screened with antibodies directed against purified hamster tyrosinase.  Sixteen independent clones which gave a positive signal were isolated from 5 x 105 independent plaques.  cDNA inserts of 13 clones among the 16 candidates cross-hybridized with each other, indicating that they were from related mRNA species.  mRNA homologous to a representative cDNA .lambda. mel 34 was expressed specifically in melanocytes, detecting an approximately 2.4 kb mRNA species of human melanocytes.  The nucleotide sequence of the three overlapping cDNA inserts spanning 1.88 kb was determined and an amino acid sequence was deduced.  The human tyrosinase is composed of 548 amino acids with a molecular weight of 62,160 excluding a hydrophobic signal peptide. Mouse genomic DNA blot analysis revealed that the gene for mel 34 was deleted in albino mouse homozygous for the deletion at and around  the albino locus on chromosone 7.  It is concluded that A mel 34 contained cDNA encoding human tyrosinase.  Moreover, the cDNA gene for human tyrosinase was recovered from the .lambda. mel 34 and can be used for many purposes including the production of pure human tyrosinase.     In addition, the three clones of the 11 not represented by .lambda. mel 34 are represented by .lambda. mel 17-1.  The gene for  .lambda.mel 17-1 cDNA was not mapped at the albino locus, detected single hybridizing restriction fragment in human and mouse DNA, and was highly conserved from mouse to human. The abundance of .lambda. mel 17-1 cRNA paralleled the melanin content in human and mouse melanocytes.  The expression of .lambda. mel 17-1 cRNA was elevated after stimulation of mouse and human melanoma cells with MSH or/and IBMX, and U-V light (such as suntan).  This was also closely correlated with the elevation of melanin content.  The fact that the .lambda. mel 17-1 gene is conserved evolutionarily indicates that the molecule encoded by the .lambda. mel 17-1 has biologiacally important functions.            The expression of that gene is controlled by hormones (MSH) or U-V light and positively correlated with the melanin content. These data indicate that the gene is involved in melanin biosynthesis in addition to tyrosinase.  Current studies suggest that .lambda. mel 17-1 gene product act on melanin biosynthesis's pathway distal to tyrosinase.

Abstract: ABSTRACT            Processes and apparatus of this kind are of use for wrapping palletized loads on their vertical front  side and rear surfaces.          A vertical transverse film curtain which  extends before the front surface of the load from  two film reels having stationary vertical spindles and disposed on either side of a powered conveyor carrying the load  is first produced  by means of a transverse weld.   The load moves towards the curtain.   The curtain is deformed transversely substantially into a substantially  U-shaped contour to cover the front and side surfaces of the load.   The same stops when it has passed the reels.   The curtain is deformed transversely on either side of the load to apply the film to the rear surface so as to be closed on itself.   By means of cutting and welding jaws the curtain is cut, and double-welded transversely to disconnect the wrapped load from the film coming off the reels and to restore a film curtain for a subsequent wrapping cycle for another load.
