Abstract: RETROVIRAL PACKAGING CELL LINES AND PROCESSES OF USING   SAME            Abstract of the Disclosure This invention provides a mammalian cell useful  for retroviral packaging comprising two plasmids, both of which  comprise  the  5'  long  terminal  repeat  (LTR) sequence from a helper virus, neither of which comprise a functional ? packaging sequence or a 3' LTR from the helper virus, one of which comprises the env gene from the helper virus and the other of which comprises the gag  and  pol  genes  from  the  helper  virus.    This invention  also  provides  a  process  for  preparing  a producer cell useful for transferring a foreign gene into  a mammalian  cell  which  comprises  treating  the above-described mammalian cell with a vector plasmid so as to insert the vector plasmid into the cell and thus create the producer cell, the vector plasmid comprising the foreign gene,  a functional ?  packaging sequence from the helper virus, both the 5' and 3' LTRS from the helper virus, and  a  gene  encoding  a  selectable  or identifiable  phenotypic  trait,  and  recovering  the producer cell so created.

Title: High speed digital signal framer-demultiplexer
Inventor: HUBBARD WILLIAM M
IPC: H04Q11/04
Filed: 1989-02-20
Granted: 1992-10-20
Abstract: ABSTRACT OF THE DISCLOSURE         A framer-demultiplexer circuit provides means for reducing the high serial bit-stream rate of byte-interleaved low level signal frame structures proposed by the Synchronous Optical Network (SONET) signal hierarchy to speeds which can be processed with low-power low-cost CMOS VLSI technology, while establishing and maintaining basic byte integrity.  In this circuitry the incoming high-rate serial bit stream is divided alternately between shift registers 43, 44 under the control of a single high-precision clock-division circuit to provide a multi-bit formatting that enables parallel delivery of staged bytes with a multifold reduction in transmission to a rate within the processing capabilities of CMOS devices.  Necessary synchronization of the register and latching elements of the circuit with the incoming bit stream is effected through use of comparator means 62, 64 which detect key bit patterns within the standard framing bytes for controlling the phases of the bit-distribution and byte out-latch clocks 41, 48. Additional comparator circuitry 34, 35, 36 employs framing byte sequences established during synchronous byte output to detect and signal the occurrence of fram structure benchmarks from which data-processing CMOS circuitry can determine the boundaries of data bytes within the parallel byte output from the demultiplexed frame.  The phase-control bit sequence comparator circuitry 62, 64 is disabled during periods of satisfactory frame processing, but is reactivated upon the detection of framing sequence error to provide resynchronization in order to ensure recovery of properly restaged data bytes.

Abstract: A carton contains a flap on the outer top panel and a flap on the inner top panel, the free edge of the outer top panel flap overlying the inner top panel flap. When a user presses down on the outer top panel flap, it pivots out of the way to allow the user's fingers to fold the inner top panel flap under the top panel structure to provide a handle for lifting the carton. When the fingers are withdrawn, the outer top panel flap is biased upwardly by its arcuate foldable connection to close the handle opening. If the inner top panel flap is contacted by the outer top panel flap as it pivots upwardly, the outer top panel flap pushes the inner top panel flap up to a substantially closed position. Score lines extending from the ends of the foldable connections of the inner and outer top panel flaps to the corners of the carton distribute the lifting stresses to the side panels of the carton.
