For a stable, easy-to-handle fire basin for burning wood and similar fuels, consisting of a plurality of segments () which are supported on the ground with feet () and towards the top have a plurality of segment surfaces () to form the tub-shaped fire basin (), the invention proposes that the segment surfaces () of the fire basin () also have or form concave depressions or recesses.

Fire basin

The aim of the invention is to comfortably handle a combustion light, in particular in the form of a wind light, comprising a firing agent, preferably a wax candle, a base (), and a preferably translucent housing part (), and a carrier tray () for the firing agent. This aim is achieved, according to the invention, in that the carrier tray () is mounted on a cardanic suspension () about two axes (--) in an overhead pivotable manner. The invention further relates to a suspension having a lower part, wherein the cardanic suspension () is pivotable about the two pivot axes thereof by more than 90&#xb0;, in particular by 180&#xb0;, wherein in said pivot position, the upper housing part () is arranged below as a base, and the lower part () is then positioned on the top as a covering.

Burning lamp, in particular wind light and suspension thereto

In order to improve the safety and handling of a brazier () for burning wood and similar fuels, comprising a substantially pot-shaped basket () and a fire pan (), it is suggested that the fire pan () is mounted on the basket () such that these can pivot relative to one another, particularly tipping by 180&#xb0; or 'overend' from the operating position into a fire-extinguishing position, the basket () that lies above when in said extinguishing position serving as the cover hood that puts out the fire. This brazier can also be in the form of a tea light, a standard or table lamp or a pendant lamp.

Brazier

A process for preparing trioxane by converting methanol to formaldehyde by dehydrogenation at a temperature of 300 to 1000&deg; C., in the presence of a catalyst, wherein the catalyst is generated physically separately from the reactor and at a temperature above the dehydrogenation temperature, and trimerizing the formaldehyde prepared in this way to give trioxane. Also described is a process for preparing polyoxymethylene and polyoxymethylene copolymers from the formaldehyde.

Process for preparing trioxane, polyoxymethylene and polyoxymethylene copolymers

Fluorinated emulsifier acids can be isolated from wastewater by firstly removing fine solids and/or material which can be converted into fine solids from the wastewater, preferably by precipitation, subsequently bringing the wastewater into contact with an anion-exchange resin and eluting the adsorbed emulsifier acids from the latter.

Method for recovering fluorinated alkanoic acids from waste waters

The invention relates to a method for removing fluorinated emulsifying agent acids from waste waters, characterized in that the finely dispersed solids in the waste water are stabilized with a nonionic or cationic surfactant or an analogous acting surface active substance, the fluorinated emulsifying agent acids are subsequently bonded on an anion exchange resin and the fluorinated emulsifying agent acids are eluted from the latter.

Process for the recovery of fluorinated alkandic acids from wastewater

An apparatus for preparing formaldehyde from methanol by dehydrogenation in a reactor in the presence of a catalyst at a temperature in the range from 300 to 1000&deg; C., a carrier gas stream which has a temperature above the dehydrogenation temperature is fed to the reactor.

Apparatus for the preparation of formaldehyde from methanol

The invention relates to a method for producing formaldehyde from methanol by non-oxidative dehydrogenation, in a reactor, in the presence of a catalyst at a temperature between 300 and 1000&deg; C. Said method is characterized in that the generation of the catalyst takes place spatially separate from the reactor and at a temperature greater than the dehydrogenation.
