The paper presents the results of durability tests for the indexable knives, implanted with nitrogen. The results for non-implanted tools are also included. The selected knives contained edge defects. The defects with the character presented in this paper had a minor impact on the durability of the investigated tools.

“Thermodynamic steam traps used in the wood industry”. We use three big families of demountable steam traps in the wood industry – mechanical steam traps with closed or open float, thermodynamic and thermostatic steam traps. In addition to these families dismountable steam traps have appeared on the market. They are produced in thermostatic and mechanical float versions. For heating devices, in which we have to deal with heat load, changing in the wide broad, which may lead to suspension of the condensate, we use pumping steam traps combining the features of float steam traps and portion pump. Using appropriate steam trap selection criteria, we are able to eliminate energy loss due to steam loss.
