The nozzle includes an interior passage for receiving the air flow, a mouth for emitting the air flow, and a plurality of stationary guide vanes located within the interior passage and each for directing a portion of the air flow towards the mouth. The nozzle defines an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth.

A fan assembly for creating an air current includes an air outlet mounted on a stand. The stand includes a base and a body tiltable relative to the base. The fan assembly has a centre of gravity located so that when the base is located on a substantially horizontal support surface, the projection of the centre of gravity on the support surface is within the footprint of the base when the body is in a fully tilted position.

A fan assembly for creating an air current includes an air inlet, an air outlet, an impeller, a motor for rotating the impeller to create an air flow passing from the air inlet to the air outlet, the air outlet comprising an interior passage for receiving the air flow and a mouth for emitting the air flow, the air outlet defining an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth, a control circuit for controlling the motor, a remote control for transmitting control signals to the control circuit, and at least one magnet for attaching the remote control to the air outlet.

In some embodiments, the device may include a third coupling mechanism which only releases the delivery unit after the engagement and disengagement which follow a triggering.

The invention relates to an integrated turbine set based on permanent magnetic and magnetic suspension technologies. Turbomachinery is high in sealing performance, complex in gear system and large in energy loss. A turbine and a generator (or a motor) of a full-sealing structure are arranged on the same rotary shaft. One end of the rotary shaft is arranged in the turbine to conduct gas expansion (or compression). The other end of the rotary shaft is arranged in the generator (or the motor), a generator rotor is arranged, and a generator stator core and a winding are arranged on the outside of the generator rotor. A magnetic suspension supporting bearing and a magnetic suspension thrust bearing are sequentially arranged at the tail end of the shaft. All components of the generator are arranged in a generator casing. The generator (or the motor) and the turbine keep the same rotation speed and adopt the same casing, shaft-end sealing is not required, and a work medium of the whole turbine set can be absolutely free of leakage. A magnetic suspension bearing achieves non-contact supporting of the rotor, friction loss of the bearing is avoided, and the overall efficiency of the turbine set is improved.

A conveyor grate for the transport and cooling of bulk material, for example cement clinker, comprises a grate floor having multiple planks (12), adjacently situated transverse to the direction of transport on associated support structures and operationally moved longitudinally relative to one another individually or in groups, with moving gaps (14) designed as blow openings situated therebetween, and a method for operating such a conveyor grate. The mutually facing side edges or side edge regions of two adjacent planks (12) form two complementary, mutually engaging profiles between which the moving gap (14) is formed. In the method according to the invention, at least a quantity of the cooling air is blown through the moving gaps (14) which is sufficient to blow the moving gaps (14) completely open.

A sheathed-element glow plug is used to be situated in a chamber in an internal combustion engine. The sheathed-element glow plug has a housing, a pin-shaped heating element, which extends partially from the housing and a pressure sensor which is situated in an inner chamber of the housing. A prestressing sleeve is provided, in this context, which applies a prestressing to the pressure sensor.

A drive system (2) for a motor vehicle (1) has a transmission (11) for driving at least one drive axle (13, 14) of the motor vehicle (1). An internal combustion engine (3) optionally is connected operatively to the transmission (11) or decoupled therefrom. A first electric machine (17) optionally is connected operatively to the at least one drive axle (13, 14) or to an output shaft (39) of the transmission (11) or decoupled therefrom. A second electric machine (19) is connected operatively to the internal combustion engine (3).

The invention provides a method for driving a hybrid drive system, wherein the drive system comprises a first drive source with an outputting shaft, a second drive source with an outputting shaft, a drive shaft connected to the outputting shaft of the second drive source, and a clutch connecting the outputting shaft of the first drive source and the outputting shaft of the second drive source, wherein, the clutch is a three-state outrunning clutch with an outrunning state, a jointing state and a two-way separating state. The method comprises the following steps: according to different operating conditions of the drive system, the three-state outrunning clutch is controlled to be in the outrunning state, the joint state and the two-way separating state respectively; and when the three-state outrunning clutch is in the two-way separating state, the two drive sources can run independently without interference or resistance, thereby increasing the utility rate of energy and facilitating control.

A motor vehicle, includes a drive motor for driving the motor vehicle, at least one additional motor and at least one differential for distributing a torque generated by the drive motor and transmitted by a drive shaft to a driven differential element of the differential to two output shafts. The motor vehicle includes a coupling device which can be controlled by a control device, and in a first coupling state directly or indirectly couples the additional motor with an output shaft, thereby rendering the distribution of the drive torque to the output shafts dependent on an additional torque exerted by the additional motor, and in a second coupling state directly or indirectly couples the additional motor with the driven differential element.

An optical unit is disclosed which is capable of being easily assembled, enabling its optical element to smoothly move, and preventing friction loss from being generated around its nut member. A lens driving apparatus is provided for moving an optical element holder, which supports an optical element having an optical axis and is movable along a guide member, in an extension direction of the optical axis, using a nut integrally provided at the holder, and a lead screw threadedly coupled to the nut to rotate forward and backward by a driving unit. In the lens driving apparatus, the forward or backward rotation of the motor is transmitted to the lead screw via a reduction gear train. The lead screw is installed to be inclinedly movable with respect to the extension direction of the optical axis about threaded coupling portions of a threaded section of the lead screw and the nut.
