Abstract: A table arrangement has a mounting element to be fastened to a fastening structure element. A first table element is connected to the mounting element, pivotally relative to the mounting element about a first pivot axis between a stowage position, in which the first table element extends substantially parallel to a mounting plane defined by the mounting element, and a position of use, in which the first table element extends substantially perpendicular to the mounting plane. A second table element is connected to the first table element substantially parallel to the first table element and rotatable relative to the first table element about a rotation axis that is parallel to the mounting plane in the position of use.

Abstract: A process for the preparation of 4-hydroxy-2,2,6,6-tetramethyliperidine (HTMP) by hydrogenation of triacetonamine (TAA) in the presence of an Ni, Co, Ru, Rh, Os or Ir hydrogenation catalyst is described. The process is carried out in the melt without a solvent.

Abstract: A process for the production of 2-aryl-2H-benzotriazoles comprises reducing and cyclizing the corresponding o-nitroazobenzenes with hydrogen at a temperature in the range of about 20.degree. C. to about 100.degree. C. and at a pressure in the range of about 15 psia (1 atmosphere) to about 1000 psia (66 atmospheres) in an organic solvent mixture containing an organic amine at a pH over 10 in the presence of noble metal hydrogenation catalyst, preferably palladium. High yields of pure product are obtained with a concomitant reduction of undesired by-products and a reduction in effluent pollution problems.
