An ink jet printer ink comprising effect pigments and organic solvents or solvent mixtures, wherein the effect pigments comprise a) aluminum effect pigments having a mean thickness in a range of 10 to 100 μm and a d98 value of the cumulative frequency distribution of the volume-averaged size distribution function of less than 15 μm and/or b) pearlescent pigments having a d90 value of the cumulative frequency distribution of the volume-averaged size distribution in a range of 3.5 to 15 μm. The viscosity of the ink jet printer ink is 1 to 50 mPa*s and the weight ratio of effect pigment to binder is 2 to 15. The invention further relates to the use of the ink jet printer ink.

A coating based on diamond-like is formed from a plurality of films of diamond-like carbon formed alternatingly over one another and in this respect a film in which no portion or only a much lower portion of doped fluorine is contained. A film in which fluorine or at least fluorine with a higher portion than the film arranged thereunder or thereabove are formed alternatingly over one another. The coating could be manufactured by using a target of pure carbon. Films are deposited on a surface of a substrate by means of a PVD process, with the portion of fluorine contained in doped form. Films are formed alternately being varied by varying a supplied volume flow of a fluorine/carbon compound or sulfur/fluorine compound as a precursor.

The present invention relates to a method of regenerating a ruthenium catalyst suitable for hydrogenation, which comprises flushing the catalyst with inert gas in a regeneration step until the original activity or part of the original activity has been attained. The method is particularly useful for ruthenium catalysts which are used for the hydrogenation of aromatics.

A covering system includes a flexible, web-like membrane having first and second portions. A first cross support is connected to the first portion of the membrane, and a second cross support is connected to the second portion of the membrane. A drive mechanism is provided for moving the second cross support relative to the first cross support so that the membrane is movable between a first, retracted position and a second, deployed position. The drive mechanism includes a force multiplication mechanism for facilitating a longitudinal tensile stress application to the membrane when it is in the second, deployed position. A transverse tensioning mechanism that includes a catenary linkage is also provided for tensioning the membrane in a direction that is transverse to the longitudinal direction.
摘要:
A tube unit for the enteral feeding of a patient, with a tube segment that extends along at least a segment of the axial direction (S) and a retention device on the distal end of the tube segment, which extends in at least one direction radially to axial direction (S) beyond the distal end of the tube segment in an extended position and which has a smaller diameter in an elongated position, in which the retention device is elongated along axial direction (S). The retention device moves from an extended position into the elongated position is supported by a control device.

An apparatus for combining under sterile conditions a liquid component held in a first container and a solid or liquid component held in a second container is provided. In one embodiment, two hollow bodies for receiving the two containers are provided, the two hollow bodies being arranged one within the other and being slidable relative to one another in a guided manner in the longitudinal direction. A cannula holder forms a pot-shaped structural unit with the first hollow body. Alternatively, the cannula holder is provided with at least one cannula. The cannula holder and the first hollow body may be separate components, in which the cannula holder is pot-shaped.
摘要:
A mixture of platelet-shaped, copper-containing metallic effect pigments having a copper content of 60% to 100% by weight, based on the total metal content, with at least one further component, where the copper-containing metallic effect pigments have a thickness distribution, determined via thickness counting by scanning electron microscopy (SEM) and represented as cumulative undersize distribution, a) with an h50 of 10 to 100 nm, and b) with an h90 of 20 to 150 nm, and in that the at least one further component is a cellulose derivative selected from the group consisting of alkylcellulose, hydroxyalkylcellulose, alkyl(hydroxyalkyl)cellulose, and mixtures thereof, and/or is at least one additive having antioxidative and/or radical-inhibiting properties. The disclosure further relates to a method for producing this mixture, and to a coating composition.

The invention relates to an insulating device containing a first machine element, in particular an exhaust gas pipe, and at least one second machine element, in particular an exhaust manifold, that is connected to said first machine element and through which, in particular, a hot medium can flow and being connected to a unit. The insulating device at least partially surrounds the machine element and is connected to the unit. The aim of the invention is to further develop the claimed insulating device with a low amount of production and material expenditure such that mounting and demounting can be carried out in a simple manner and can be adapted in a problem-free manner to various types of units. According to the invention, a base plate that is connected to the unit is provided, said base plate having at least two side parts that are arranged at a distance from each other forming an intermediate area, such that a sliding part is arranged in the intermediate area and is essentially sealingly connected the base plate and to the lateral parts by profiles and is detachably connected in relation to the base plate, such that said sliding part contains a recess through which the second machine element is guided, and also a cover that can be connected to the base plate by a detachable securing element, said cover engaging with the first machine element. The cover rests upon the lower edges thereof on associated areas of the lateral parts of the base plate and/or the sliding part(s).
