The invention resides in an assembly for rotationally supporting a wind turbine blade () relative to a wind turbine hub (). The assembly comprises an intermediate ring () having an inner annular portion and an outer annular portion provided with means for attaching the turbine blade. The intermediate ring is rotatably mounted to the hub via a first bearing arrangement. According to the invention, the first bearing arrangement comprises a radial bearing () and a thrust bearing, whereby the inner annular portion is mounted to the hub via the radial bearing and the outer annular portion is mounted to the hub via the thrust bearing. The thrust bearing is a plain bearing comprising first and second sliding surfaces () which are clamped to the hub between first and second clamping members ().

In an inkjet print head an actuation chamber substantially extends in a first direction and the actuation chamber is associated with a piezo actuator arranged to generate a pressure wave in the actuation chamber. The pressure wave propagates in said first direction. A nozzle is associated with the actuation chamber such that a droplet may be expelled through the nozzle upon generation of the pressure wave in the actuation chamber. A reservoir is in fluid communication with the actuation chamber via an inlet and an outlet of the actuation chamber. A pump means is provided for pumping ink from the reservoir, via the inlet, through the actuation chamber, via the outlet back into said reservoir. The print head is provided with a means for reflecting the pressure wave at the outlet of the actuation chamber for enabling to generate a sufficient pressure at the nozzle for expelling the droplet.

An ink jet device with an ink reservoir and a jetting assembly, with an ink supply line being arranged to allow liquid ink to flow through the valve into the ink reservoir in accordance with and supported by gravity acting on the flowing ink, and a purging device adapted to apply a purging pressure to an inner space of the ink reservoir, wherein a passive one-way valve is arranged below a nominal minimal fill level (L) of the ink reservoir for blocking a connection of the ink supply line to the ink reservoir when a pressure within the ink reservoir is high enough but not required to be higher than the purging pressure.

An improved printing device is provided with a rotatable, cylindrical image-receiving support having a number of image-forming stations disposed along the rotational path of the image-receiving support. In each image-forming station a separation image of a required image is generated and transferred in correct registration to the image-receiving support at an image-transfer zone. Preferably, each image-forming station has a rotatable, cylindrical image-registration element and an imaging means for forming the separation image on the image-registration element. When measured along the circumference of the image-registration element in the direction of movement thereof, there is an equal distance in each image-forming station between the place where the separation image is formed on the image-registration element and the center of the image-transfer zone where the separation image is transferred to the image-receiving support.
