摘要:
The invention provides a pigment preparation comprising (a) C.I. Pigment Red 254 with an average particle size d50 of not more than 100 nm; (b) 0.1% to 30% by weight, based on the weight of the PR 254, of one or more dispersants from the group of the unlaked sulfo-containing monoazo dyes; and (c) 0.1% to 30% by weight, based on the weight of the PR 254, of a basic pigment dispersant of the formula (V)
摘要:
The invention relates to a pigment composition that is composed of compounds of formulas (I), (II) and (III), is characterized by a average particle size d50 ranging from 10 to 60 nm, less than 5% by volume of the particles being greater than 70 nm, and can be obtained by reacting of 1 mol of a succinic acid diester with 2 mol of a mixture of nitriles A-CN and B-CN nitriles, the molar ratio of A-CN and B-CN in the nitrile mixture being in the range from 99.5:0.5 to 85.0:15.

摘要:
A process for producing high-purity azo colorants is characterized in that (a) at least the azo coupling is carried out in a micro-reactor, (b) the azo-dye produced in the micro-reactor is brought into intimate contact with an organic solvent from the group of the C3-C6 alcohols, the C4-C10 ether alcohols and the halogenated aromatics at a temperature from 0 to 60° C., and (c) the azo dye produced in the micro-reactor is subjected to membrane purification in an aqueous or solvent-containing suspension.
摘要:
A method and a device increase the stopping accuracy of a moving object, in particular a rail vehicle, at a predetermined stopping point. An RFID (Radio Frequency Identification) signal generated at the stopping point is received by the object and is used as a guidance variable for approaching the stopping point.
摘要:
A sensing apparatus for ground sensing from the interior of a vehicle, comprising a sensing probe capable of being brought into contact with the ground, and a handle for moving the sensing probe from a rest position into a lower ground sensing position. The sensing probe can be coupled with the handle such that upon actuation of the handle, the sensing probe is lowered into the ground sensing position accompanied by lever action. A lowering locking mechanism can be provided for arresting a lowering movement of the sensing probe. For orientation purposes, the sensing probe can be pivotable via the handle about an essentially horizontal pivot plane, and an orientation arresting mechanism can be provided for arresting an orientation position of the sensing probe. In a vehicle having such a sensing apparatus, the sensing probe can be guided through the bottom of the interior of the vehicle.

The invention provides a process for preparing uncoated, readily dispersible C.I. Pigment Red 112 by azo coupling in a microreactor, which comprises precipitating the coupling component in an upstream microreactor and coupling the precipitated coupling component in finely divided form to the diazo component in a microreactor.The C.I. Pigment Red 112 of the invention features low dispersion harshness in alkyd resin varnish, and a PCB content of below 25 ppm.

An artillery gun having a weapon disposed on a carrier vehicle is provided and comprises a first module, containing the weapon and mounted on a gun mount and also containing at least a portion of an automatic projectile feed mechanism. A second module contains further portions of the projectile feed mechanism. A standby member disposed to the rear of a projectile transporter of the feed mechanism is displaceably guided and can be disposed in a transfer position parallel to a charger disposed on a free end of a projectile transfer arm of the first module. A third module is provided and is embodied as a munitions magazine in which are stored upright projectiles that are adapted to be grasped via a projectile transporter and, accompanied by rotation and alignment, are conveyed via the standby member and charger into a region at the rear of the end of the weapon and to be raised into a loading position. At least one fourth module forms the carrier vehicle.
