The invention provides a sulphur pellet comprising at least one H2S-suppressant, comprising in the range of from 60 to 100 wt % elemental sulphur, based on the total weight of the pellet. The invention further provides a process for the manufacture of sulphur pellets comprising at least one H2S-suppressant, comprising the steps of: (a) mixing elemental sulphur, one or more H2S-suppressants and opt...

An apparatus for treating highly corrosive agents comprises a tube bundle ( 14 ) heat exchanger ( 10 ), structured to carry out a heat exchange between two fluids one of which is highly corrosive and flowing inside of said tube bundle ( 14 ).

This invention relates to a cathode element for use in a pot of an electrolytic cell intended for production of aluminum. The cathode element comprises a cathode block and a steel connection bar. The connection bar includes at least one metal insert, whose electrical conductivity is greater than the electrical conductivity of the said steel. The presence of an insert according to the invention can...

The tool has a holohedral adhesive layer (11) divided into segments, where the tool is fixed on a horizontal tool shaft. A cooling agent supply is aligned at a front side work surface of the adhesive layer. The adhesive layer exhibits multiple synchronization chambers for a cooling agent, where the chambers are opened at a front surface of the adhesive layer. The chambers are radially extended fro...

In a card flat bar having a card flat clothing, the card flat clothing is magnetically attached to the card flat bar body and, in use, lies opposite a clothed roller. In order to hold the clothing element against the card flat bar in a structurally simple way in the event of an increase in force on the clothing, especially to prevent the card flat clothing from making contact with the cylinder clo...

The process for producing a single-piece combing clothing (5) of a combing machine with several teeth arranged next to each other in a distance, where a base area (7) of the teeth ends in a common web (8), is claimed. The combing clothing is produced by ceramic powder injection molding process, where the surface of the teeth is annealed and/or coated in connection to the powder injection molding p...

The cover (12) has an intake air pipe for supplying fresh air to an engine of a motor vehicle, where the cover is double-walled formation. Reinforcements are passed between walls along a driving direction. Channels (22A, 22B) serve as the air pipe and neighboring regions i.e. sound absorbers (24A, 24B, 24C) that are formed between the channels. The reinforcements are formed for permitting reducing...

The method involves providing heat exchangers (12, 13) with air ducts, and connecting end boxes (16, 18) with the heat exchangers such that the air ducts are opened out into an airspace of the end boxes. An intermediate box (14) is connected with the heat exchangers for a motor vehicle of one design such that the air ducts are opened out into an airspace of the intermediate box. The heat exchanger...

A comparator formed by first and second stages. The second stage is formed by a pair of output transistors connected between a power-supply line and respective output nodes; a pair of bias transistors, connected between a respective output node and a current source; a pair of memory elements, connected between the control terminals of the output transistors and opposite output nodes; and switches ...
