A composite sorbent is formed which is the reaction product of a solid alkali metal carbonate, rehydratable alumina and water or an aqueous solution of a metal salt. The reaction between the components occurs while forming particulates followed by curing and activation at high temperatures. The alkali metal in the sorbent exhibits a highly reactive and accessible state that is very favorable for various sorption applications. The sorbent is especially useful for removal of HCl and other acid contaminants from gas and liquid hydrocarbon streams at high temperatures.

The invention discloses a lighting device (100), which comprises a lamp holder (1), a slender, length-adjustable supporting pillar (2) supported by the lamp holder, and a supporting pillar (2) arranged on the supporting pillar (2). ) on the lighting unit (3).

The invention relates to an injector of an injection system of an internal combustion engine. The injector has an injector housing, a piezoelectric actuator control unit, a connection plug on the head of the injector housing, and an electrical connection between the control unit and the connection plug within the injector housing. The electrical connection comprises a contact element with elastic means for supporting the contact element against the control unit or against the connection plug. One end of the contact element bears against the control unit or the connection plug, while the other end is arranged with a corresponding spacing therefrom. In this way, movements and thermal expansions of the control unit can be compensated.

The invention discloses a method for preparing a quasi-suspending semiconductor gallium nitride (GaN) extending thin film substrate supported by a single crystal sapphire, belonging to the technical field of gallium nitride substrates. The method comprises the steps: a GaN extending thin film on the sapphire substrate is irradiated from the sapphire substrate by an ultraviolet laser beam; the energy density of the laser beam is adjusted to lead the laser beam irradiated on the GaN extending thin film to form array figures with different energy density; and a GaN extending thin film part with high irradiation energy density and the sapphire substrate generate non-damage peeling, and a GaN extending thin film part with low irradiation energy density is still connected with the sapphire substrate to obtain the quasi-suspending semiconductor gallium nitride extending thin film substrate. A mechanical support of the GaN extending thin film substrate is still supplied by the single crystal sapphire, the GaN extending thin film substrate has enough mechanical stability to be used in the following process as the substrate, and the quasi-suspending GaN thin film substrate has less extendingstress and low defect density.

The invention relates to a rotor (12) having several rotor laminations (2), which are stacked one after the other along an axis of rotation (D), wherein each rotor lamination (2) has a plurality of magnetic fins (4), which are separated from each other by nonmagnetic hollows (6), the nonmagnetic hollows (6) are arcuate and the two ends (7) of the nonmagnetic hollows are open toward an outer circumference (U) of the rotor lamination (2), the hollows (6) of at least some of the rotor laminations (2) are filled with a solid material (16). For the purpose of a simple design and improved functionality of the rotor (12), the stacked rotor laminations (2) are connected to each other only in the direction of the axis of rotation (D) in the assembled state of the rotor (12).
