Abstract: The invention relates to a machine table for a machine tool. Such machine tools are used, for example, in the wood-processing industry. The machine table comprises clamping elements, each of which has a clamping device, wherein, starting from a receiving position, the clamping elements can be raised to a raised position and lowered to a lowered position relative to a reference element.

Abstract: An embodiment of the present disclosure relates to a composition suitable for leather tanning comprising zeolite treated with monocarboxylic acid and to a method for manufacturing said composition. An embodiment of the present disclosure method comprises providing zeolite into a reactor and keeping said zeolite in motion while introducing concentrated monocarboxylic acid thereto provided that the mean temperature of the resulting composition is 50° C. or below.

Abstract: A system minimizing inorganic and organic contaminants in water circulating in a water system comprises a flow-through filter vessel containing a filter medium and whose outlet is connected by a conduit to a flow-through radiation chamber containing a source of ultraviolet light. An electrostatic probe is inserted into the conduit between the filter vessel and the radiation chamber to subject the water flowing through the conduit to an intense electrostatic field. The filter vessel, conduit and chamber are connected in series to a pump and water utilization apparatus such as a cooling tower, pool or the like so that the water circulates through the filter and the electrostatic field before it enters the radiation chamber to maximize the effectiveness of the radiation chamber in killing organic contaminants entrained in the water.
