IPC: B23K20/08
Filed: 1991-09-03
Abstract: PERMANENT WIRE SPLICING BY AN EXPLOSIVE JOINING PROCESS Abstract of the Disclosure A method and apparatus for wire splicing using an explosive joining process.  The apparatus consists of a prebent, U-shaped strap of metal 21 that slides over prepositioned wires 22.  A standoff means 23 separates the wires from the strap before joining.   An adhesive 41 holds two ribbon explosives 15 in position centered over the U-shaped strap.   A detonator 24 connects  to  the  ribbon  explosives.    The  process  involves spreading strands of each wire to be joined into a flat plane, alternating  each  strand  in  alignment  to  form  a  mesh-like arrangement with an overlapped area, sliding the strap over the strands of wires, and positioning the standoff means between the two surfaces. The detonator then initiates the ribbon explosives that drive the strap to accomplish a high velocity, angular collision between the mating surfaces.  The collision creates surface melts and collision bonding results in electron-sharing linkups.

Abstract: In an image pickup system for use in a craft (11) flying over an object zone which moves independently relative to the craft, first and second electric signals represent first and second partial zones when the craft is at first and second locations at a first time instant and at a second time instant which is later than the first time instant.  The first and the second partial zones are a forward partial zone Pf viewed by a first camera unit (13) and a backward partial zone Pb viewed by a second camera unit (14).  Due to movement of the object zone, the first and the second partial zones are different by a difference zone.  Supplied with first and second location signals produced by a location signal producing unit (15) represent the first and the second locations, a correcting signal producing unit (16) produces an overall correcting signal representative of the difference zone.  By the overall correcting signal, a processing unit (17) processes the first and the second electric signals into first and second image signals for use in producing a stereo image of the object zone.  An equivalent of the location signal producing unit may be located in a terrestrial station (20).

These cell lines offer a rapidly repriducible, continuously-available sourse for the production of taxol and taxol-related  compounds.  This production may be scaled to commercial levels by use of the cell lines in bioreactors.   The cell lines  provide screening  assays for species and cultures of Taxus that are sources of taxol and taxol-related compounds.
