Abstract: A power contacting device includes a contact pin (1) and at least one contact pin receptacle (2) penetrated by the contact pin in the operating state. To provide a power contact which permanently ensures high-quality contacting, even when the contacted components move relative to one another, the contact pin receptacle (2) has a first guide arrangement (3) which is fixed to a component in the operating state and a second guide arrangement (4) which is conductively connected to the first guide arrangement, the second guide arrangement (4) being arranged displaceably on the first guide arrangement (3) and the contact pin (1) conductively contacting at least the second guide arrangement (4) in the operating state.

Abstract: Glycidyl methacrylate is produced by transesterifying methyl methacrylate with glycidol in the presence of a polymerization inhibitor and a transesterification catalyst in which the catalyst is a salt of formula MeX where Me is an alkali metal ion and X is a cyanide, cyanate or thiocyanate ion.

Abstract: Catalysts used in the epoxidation or hydroxylation of water soluble olefinic compound with hydrogenperoxide are recovered by separating the catalyst as a distillation residue, the distillation residue is introduced into an inert material which is in whirling movement, e.g., as a fluidized bed, the organic compounds contained in the distillation residue are burned with oxygen or oxygen containing gases whereupon the catalyst compound separated on the inert whirling material together with the portion of the catalyst compound which accumulates in the solids separator connected at the outlet of the reactor is dissolved in water and the solution obtained again used for epoxidation or hydroxylation.

Abstract: Very pure carboxylic acid-1-monoglycerides are prepared by reacting a carboxylic acid with glycidol at a temperature of 80.degree. to 200.degree. C. in the presence of a basic alkali metal or alkaline earth metal compound as a catalyst in the presence of an inert solvent which forms a homogeneous solution with the reactants at the reaction temperature.

Abstract: Glycide is prepared by reacting allyl alcohol with hydrogen peroxide in the presence of a tungsten compound as a catalysts the excess allyl alcohol and the greatest part of the water distilled off, the sump mixture obtained in the distillation is split at 110.degree.-220.degree. C. and 5 to 60 torr in a thin layer evaporator into a volatile portion which is predominantly glycide, high boiling by products and the residual part of the water and a sump portion of glycerine, polyglycerine and catalysts. The volatile liquid portion is broken into glycide, water and high boiling byproducts at 5 to 60 torr in a distillation apparatus directly connected to the thin layer evaporator.

Abstract: Corticoids of the formula ##STR1## wherein X is .beta.-hydroxymethylene or carbonyl, and 21-esters thereof with physiologically acceptable acids possess topical anti-inflammatory activity with relatively little systemic activity.
