Abstract: ABSTRACT OF THE DISCLOSURE     A closure assembly for a shipping and storage drum where the drum includes an internally threaded plastic outlet for receipt of the closure assembly includes a plastic closure having a generally cylindrical main body portion which is externally threaded and which constitutes the leading edge of threaded engagement into the outlet.  Disposed at the upper end of the main body portion and integral therewith is an annular, peripheral flange the underside of which is shaped with an annular groove which is designed to receive an elastomeric gasket.  The annular groove has an outwardly inclined outer wall and a generally cylindrical inner wall. The gasket is held in position as part of the closure by an interference fit between the inside surface of the gasket and the inner cylindrical wall of the groove.  The plastic outlet of the shipping and storage drum includes a generally cylindrical raised rib and outward thereto and concentric therewith a generally cylindrical raised wall.  Upon full threaded engagement of the closure into the outlet, the raised rib presses into the central area of the elastomeric gasket and the upper surface of the closure is seated within the raised wall and is below the top surface of the wall. The external threads of the closure arranged with two threaded portions, one portion being a straight thread and the lower or leading edge portion being a tapered thread. The thread pitch is the same and the threads are continuous with each other.

Title: Cytopathic viruses for therapy and prophylaxis of neoplasia
Inventor: MCCORMICK FRANCIS
IPC: A61K35/76
Filed: 1994-02-16
Granted: 2003-04-22
Abstract: Methods and compositions for treating neoplastic conditions by viral-based therapy are provided. Mutant virus lacking viral proteins which bind and/or inactivate p53 or RB are administered to a patient having a neoplasm which comprises cells lacking p53 and/or RB function. The mutant virus is able to substantially produce a replication phenotype in neoplastic cells but is substantially unable to produce a replication phenotype in non-replicating, non-neoplastic cells having essentially normal p53 and/or RB function. The preferential generation of replication phenotype in neoplastic cells results in a preferential killing of the neoplastic cells, either directly or by expression of a cytotoxic gene in cells expressing a viral replication phenotype.

Title: Multiple emitters laser diode assembly with graded-index fiber microlens
Inventor: LABRANCHE BRUNO
IPC: H01S5/40
Filed: 1995-12-14
Granted: 2001-12-04
Abstract: The  multiple  emitters  laser  diode  assembly comprises a laser diode bar for emitting a laser beam. The laser diode bar comprises a plurality of emitters aligned with respect to each other in a same plane of emission. A graded-index elongated fiber microlens is transversely set at a given distance in front of the laser diode bar for controlling the divergence of the beam.   The  microlens   has   an  axis  of   symmetry substantially intersecting the optical axis of  each emitter.  A  mount  is  provided  for  positioning  the microlens  with  respect  to  the  laser  diode  bar. Alternatively, the assembly may comprise a laser diode array for emitting the beam.  The laser diode array comprises a plurality of substantially parallel rows of emitters with a substantially regular period between them.  An  array  of  graded-index  elongated  fiber microlenses is positioned substantially parallel to the rows. Each microlens corresponds to one of the rows for collimating the beam generated thereby. The GRIN fiber microlens shows less alignment sensitivity than ordinary fiber lens or aspherical fiber lens when used in a multiple emitters laser diode assembly. The GRIN lens further has the advantage of collimating a laser diode bar  or  array with  a  high degree  of  quality while minimizing  phase  aberration  and  distortion in  the collimated transmitted beam.

Abstract: A reference oscillator (118) in a communication device (100) such as a radiotelephone is controlled by temperature compensating the reference oscillator (118). At the time of manufacture, characterizing data are stored in non-volatile memory (128) in the communication device (100). When the communication device (100) is powered up, the characterizing data are read and used to provide an initial correction (206) to the output frequency of the reference oscillator (118). Subsequently, an automatic frequency control operation is performed using the RF signal received from a remote transmitter as a reference signal. A frequency correction is determined (214) in the form of a frequency step size and step direction. The output frequency of the reference oscillator is repeatedly stepped until frequency error is minimized.
