摘要:
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.
摘要:
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.
摘要:
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.

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.
