Abstract: TiO2-supported catalysts include at least molybdenum or tungsten as active components for hydrotreating processes, in particular for the removal of sulfur and nitrogen compounds as well as metals out of crude oil fractions and for the hydrogenation of sulfur oxides.

Abstract: A lamp socket including socket contacts for electrically contacting lamp holder contacts, the lamp socket including a mounting dome that is insertable into a lamp holder and includes a support pin that is linked in a spring elastic manner so that the support pin mechanically anchors the lamp socket in the lamp holder, wherein the mounting dome includes support surfaces which form a movement path along which the support pin is moveable, wherein the movement path displaces the support pin from an idle position in a first direction through a displacement section while building up a spring load during a relative movement of the lamp socket and the lamp holder, wherein the movement path returns the support pin through a return section towards an idle position of the support pin partially reducing the spring load during a relative movement of the lamp socket and the lamp holder.

Abstract: A light fixture for supporting a lamp at two ends, the light fixture including a lamp holder which receives and supports a lamp socket arranged at a first end of a lamp, wherein the lamp holder includes lamp holder contacts which electrically connect with lamp socket contacts; and a support which receives and supports a support element arranged at a second end of the lamp, wherein the support mechanically supports the lamp in the light fixture and does not include electrical contacts, wherein the support is essentially pot-shaped, wherein two opposite face walls are arranged at a base of the support, wherein the face walls and the side walls define a receiving cavity which is accessible through an opening and which includes a push-in section arranged in front in a push in direction and a support section arranged in a rear in the push-in direction.

Abstract: A particulate porous spherical titanium dioxide has a TiO2 content of at least 99.0% by weight, a particle size d50 in the range of 30 to 350 ?m, a tight particle size distribution (B 90/10) in the region of a maximum of 120 ?m, a pore diameter of 1 to 30 nm, a pore volume of at least 0.1 cm3/g, and a surface area of 30 to 300 m2/g (BET).

Abstract: A pivot lever actuation unit including an actuating handle which can be folded out of a recess and then swiveled, and an adapter part which can be screwed on under the recess. The actuation unit has a modular construction allowing certain external component parts to be exchanged, and also enables a flexible rebuild.

Abstract: A swivel lever actuating mechanism including a trough. The trough has a shoulder which pierces the fastening plane formed by the thin wall in the direction toward the other side of the thin wall. The trough also supports a drive shaft at which a hand lever with a projection is arranged which is swivelable out of the trough. First locking devices proceed from the trough or hand-lever-projection and cooperate with second locking devices. Independently acting locking devices are provided for the free end of the hand lever. A mechanical drive provided with a cam is arranged in the hand-lever-projection so that the cam moves the locking devices into the open or closed position when the mechanical drive is actuated. A pin with an electric drive is arranged in the trough so that the locking devices are moved into the closed or open position when the electric drive is actuated.

Abstract: Nonaqueous ionic ligand liquids of the formula (Q.sup..sym.)a A.sup.a-, where Q.sup..sym. is a singly charged quaternary ammonium and/or phosphonium cation or the equivalent of a multiply charged ammonium and/or phosphonium cation and A.sup.a- is a sulfonated triarylphosphine, a process for preparing them and their use as catalyst constituents.
