Title: Test assembly for subterranean well - can be fitted in blowout preventer between upper and lower conduits
IPC: E21B33/038
Filed: 1981-05-11
Abstract: A test assembly can be fitted in a blowout preventer stack above a well and between upper and lower conduits that extend to a production zone. It consists of first and second members carried by the upper and lower conduits respectively. A lock arrangement secures the members with the conduits in communication with each other. A shifting arrangement can shift the locking from such a first position to a second position where the conduits are disengaged from communicating. Locking is by an inwardly or outwardly extending projection on each of the members and a lock member having a recess contoured to receive the projections. Shifting is caused by an axially movable member for moving the lock member between positions where the recess receives the projections and does not receive them. Test assemblies are provided that can be fitted within a blowout preventer stack above a well and between an upper conduit and a lower conduit that extends to a prodn. zone of the well.

Title: Prodn. of oxide catalysts contg. molybdenum - and bismuth or tellurium, using organic suspension medium
IPC: B01J27/199
Filed: 1982-02-11
Abstract: Prodn. of mixed oxide catalysts contg. Mo and either Bi or Te is carried out by calcining a coprecipitate or gel precursor in an O2-contg. gas, where the precursor is derived from a suspension in which the liq. phase comprises methanol, ethanol and/or a non-alcoholic organic liq. The catalysts are useful for oxidn. and/or ammoxidation of alkenes, e.g. in the mfr. of (meth)acrolein, (meth)acrylic acid or (meth)acrylonitrile, but are specified in the claims as "first-stage" catalysts, i.e. catalysts with high activity for conversion of propylene to acrolein but low activity for conversion of acrolein to acrylic acid. Use of an organic medium instead of water produces catalysts giving increased yields of acrylonitrile in the ammoxidation of propylene, and increased yields of butadiene in the oxidative dehydrogenation of 1-butene.
