Abstract: The present invention relates to a throttle-valve housing having a continuous throttle opening for a throttle-valve which is arranged on a throttle-valve shaft, and a housing having a housing cover and a housing body. An electric drive and a first electronic mechanism for the drive are arranged in the housing, for displacing the throttle-valve shaft. The throttle-valve housing is especially non-complex in terms of production and assembly, and can be especially easily connected to other electronic mechanisms of the motor vehicle. To this end, the first electronic mechanism for the electric drive and the second electronic mechanism for appliances outside the housing are arranged in the cover of the housing.

Abstract: Bimodal polyethylene blends are made from a high-molecular-weight ethylene copolymer and a low-molecular-weight ethylene homo- or copolymer and have a melt flow rate MFR 190/21.6 of from 6 to 14 g/10 min, a density of from 0.94 to 0.97 g/cm3, an environmental-stress-cracking resistance ESCR>150 h and a value of less than 3 when the quality of blending in the blend is measured to ISO 13949. A process prepares polyethylene blends of this type by melting and homogenization in a mixing apparatus and discharge via a gear pump. The blends are used to produce moldings, in particular hollow articles and pressure pipes.

Abstract: Photopolymerizable recording materials suitable for producing photoresist layers and lithographic printing plates are composed of one or more photopolymerizable olefinically unsaturated organic compounds, optionally a polymeric binder, one or more photopolymerization initiators, a color-forming system which on irradiation with actinic light causes an increase in the color intensity of the recording material, a sensitizer and optionally further additive and/or auxiliary substances, and contain as the color-forming system(a) one or more colorless or virtually colorless organic compounds which are oxidizable to colored compounds, and(b) a photooxidant for the colorless or virtually colorless organic compound(s) (a),wherein photooxidant (b) comprises an organic salt with a substituted or unsubstituted hetaromatic system, this hetaromatic system having one or more built-in groups of the general formula (I) ##STR1## where R is substituted or unsubstituted alkenyl, alkynyl, hetaryl, alkoxycarbonyl, carbamoyl, alkyls

Abstract: Hexaarylbisimidazoles I ##STR1## where Ar.sup.1, Ar.sup.2 and Ar.sup.3 are each aryl, of which Ar.sup.2 and Ar.sup.3 can be linked to form an anellated ring system, are prepared by oxidizing the corresponding triarylimidazoles II in an aqueous/organic two-phase system in the presence of active amounts of an onium salt III.
