  • Process for preparing acrylic acid from ethylene oxide and carbon monoxide
    Patent number: 9115070
    Abstract: A process for preparing acrylic acid from ethylene oxide and carbon monoxide, in which ethylene oxide is carbonylated in an aprotic solvent with carbon monoxide in the presence of a cobalt catalyst system to give poly-3-hydroxypropionate, the cobalt content in the poly-3-hydroxypropionate formed is reduced with the aid of water and/or an aqueous solution as a precipitation and/or wash liquid, and the poly-3-hydroxypropionate is subsequently split by thermolysis to give acrylic acid.

  • Guidance mechanism for a subcaliber-sized fin-stabilized practice projectile
    Patent number: 4978088
    Abstract: A guidance mechanism for a subcaliber-sized fin-stabilized practice projectile including wings or vanes which are radially fixedly arranged on the shank of the projectile. The wings or vanes possess auxiliary vanes which extend transversely of their main axes, and wherein a hole which is produced in a target board by the fin-stabilized practice projectile corresponds, in general, with the diameter of a circle about which the auxiliary vanes are located on the projectile.
