An inspection apparatus for the internal inspection of tubular members has a body 1 adapted for insertion into the tubular member and the body has an inspection window 2. A projection means including a laser 14 and associated reflectives 13, 10 and 9, the reflective 9 being rotated by a motor 7, is directed such that a beam of radiant energy is directed through the window to illuminate an axial ex...

A tool actuator which comprises a casing (8) containing a pipe (1), which is movable from a locking position to an unlocking position, under the action of a fluid pumped through the casing. When the pipe is in the locking position it locks a mandrel (4) in an activating or deactivating position. When the pipe is in the unlocking position it does not contact the mandrel which is therefore free to m...

Spinnable and formable solutions of polyamideimides and process for their preparation. They contain 5 to 30% of a polyamideimide in a solvent mixture comprising 40-80% by weight of gamma -butyrolactone and 20-60% of an aprotic amide solvent. They are obtained by reaction, in gamma -butyrolactone as a polycondensation solvent, of a diisocyanate, of an aromatic acid anhydride, optionally of a...

Xanthan gum is thermally treated while in the dry state ( 15% moisture or less) to render its room temperature 24 DEG C(75 DEG F.) hydration viscosity (V1)/higher temperature 41 DEG C(150 DEG F.) viscosity ratio (V2) between 1.02 and 1.45 as described by Food Chemical Codex. This process will either increase the room temperature 24 DEG C(75 DEG F.) hydration viscosity (V1) and/or decrease the high...
