Abstract: A fluid-actuated working cylinder having a cylinder housing enclosing a cylinder chamber and having a cylinder tube whose inner circumferential surface forms a piston running surface for a piston arranged in the cylinder chamber wherein the cylinder tube is a composite body having a tubular inner layer and a tubular support jacket surrounding the tubular inner layer with a radial support effect and wherein the tubular inner layer is made of a diffusion-tight glass material or ceramic material, while the support jacket has a cellulose-containing and/or lignin-containing material structure.

Abstract: A head-up display for a transportation vehicle. The head-up display includes an imaging unit for generating an image, and an optical system for projecting the image onto a projection surface. The optical system includes at least a first mirror, a curved second mirror arranged adjacent to the first mirror, and a selectively reflective element configured in an optical path between the first mirror and the second mirror. The optical system is configured such that light emitted from the imaging unit is directed to pass through the selectively reflective element, reflected off the first mirror towards the selectively reflective element, reflected by the selectively reflective element towards the second mirror, and reflected by the second mirror towards the selectively reflective element, and passed through to be directed to the projection surface.

Abstract: A voltage supply for a mass analyser is provided. The voltage supply comprises a voltage source, a first voltage output, a second voltage output, and a voltage divider network. The first voltage output is configured to provide a first voltage to a first electrode of the mass analyser, wherein the first electrode of the mass analyser has a first mass shift per volt perturbation. The second voltage output is configured to provide a second voltage to a second electrode of the mass analyser, wherein the second electrode of the mass analyser has a second mass shift per volt perturbation. The second mass shift per volt perturbation opposes the first mass shift per volt perturbation. The voltage divider network comprises a first resistor and a second resistor.

Abstract: There is provided a drinks stirrer (10) for stirring an infusion pouch within a drink. The infusion pouch comprises a pouch soring an infusion media, a tag for holding the infusion bag, and a string connecting the pouch to the tag. The drinks stirrer (10) comprises a proximal end (14) having a retainer device (32, 34) for retaining the tag to the proximal end, and a distal end (12) having a scoop (20) for holding the pouch. The scoop (20) comprises a slot (24) for receiving the string to constrain the pouch to adjacent the scoop. A drinks apparatus comprising the infusion pouch and the drinks stirrer is also provided.

Abstract: An inductor for a converter of an electric machine includes a core defining a channel configured to receive transmission fluid on an outer surface of the core. Coils made of windings are wrapped on the core. The windings enclose an open side of the channel to define an oil flow passage, wherein oil flowing through the oil flow passage is in direct contact with both the windings and the core to absorb heat from the windings and the core.

Abstract: An additive printing device and a method for using the same to manufacture a tower structure of a wind turbine is provided. The additive printing device includes a vertical support structure, a support ring suspended from the vertical support structure, and a printer head movably coupled to the support ring for selectively depositing cementitious material. A drive mechanism, such as a rack and pinion, moves the printer head around the support ring while selectively depositing cementitious material. The vertical support structure may be raised and/or the relative position between the vertical support structure and the printer head may be adjusted to raise the printer head to print subsequent layers. This process may be repeated to print the tower structure layer-by-layer from the ground up.

Abstract: A data processing system that receives user input specifying datasets on which operations are performed with user interfaces that enable manipulation of hierarchical groups of datasets. A user interface may enable individual datasets or a previously defined group of datasets to be aggregated into another grouping. The groupings may be scoped, including by persona of users, such that, when a user is prompted to specify one or more datasets as a target of an operation by the data processing system, the available choices are limited to datasets that have a scope encompassing that user. The interfaces may prompt a user to select a grouping within the hierarchy that contains datasets on which the operation can be performed. Upon selection of a grouping with multiple datasets as a target of an operation that is performed on datasets singly, the operation may be performed on each dataset in the selected group.

Abstract: A tunnel for mounting above a road surface (3) comprises a plurality of tunnel segments (1). Each tunnel segment is adapted for mounting at least one projector (6) therein, above a respective opening formed by the tunnel segment in a ceiling of the tunnel. The openings (5) of the plurality of tunnel segments are spaced apart in succession in a direction of travel of vehicles in the tunnel. The tunnel segments are disposed such that projection surfaces (8) of the projectors are seamlessly contiguous or overlapping on the road surface in the direction of travel. The tunnel may comprise awnings positioned at its entrance and its exit, the ceiling being formed at least in part by the awnings. A first awning (10A) may be mounted to a first tunnel segment, in the direction of travel, and a second awning (10B) may be mounted to a last tunnel segment, in the direction of travel.
