It is provided that at least two first spray openings (16) have central axes (17) which intersect outside the injection valve, and / or that a centrally situated second spray opening (18) has a larger diameter than the other spray openings (16).

A device for handling stacking or removing articles from a stack, has a stacking wheel located between the lifting elements for stacks and a conveyor. When the stacking wheel turns, depending on the direction of its rotation, an article is moved from the conveyor onto the stack in the lifting direction. The stacking wheel bears pairs of holding plates distributed around its periphery; on them swivelling fingers are supported. The swivelling fingers are pressed by springs into their action position in which they project over the facing surfaces of the holding plates and fit into receiving openings of the articles when articles are moved by the stacking wheel. Control plates are assigned to the stacking wheel and engage with their ramp edges the concave, downwardly pointing surface of the swivelling fingers to swivel them into their readiness position which does not project to the inside over the holding plates.

A piston engine (1) that can be driven using a steam power process and is used in particular for utilizing waste heat from an internal combustion engine comprises at least one cylinder bore (4), a cylinder piston (5) which is arranged in the cylinder bore (4), and a rod (20) which is connected to the cylinder piston (5). The rod (20) is guided out of the cylinder bore (4). The cylinder piston (5) delimits a first operating space (9) and a second operating space (10) in the cylinder bore (4). A crankshaft (22) is disposed in a crankshaft space (21). The rod (20) is connected to a slider crank mechanism (23) which is disposed in the crankshaft space (21), the rod (20) being effectively connected to the crankshaft (22) via the slider crank mechanism (23), thus making it possible to obtain a large expansion volume while keeping the design of the piston engine (1) compact.

A method of forming a composite component in which the component comprises a series of sub -layers and in which the sub -layers are offset with respect to one or all of the other sub -layers forming the composite component.

The invention relates to a method for weaving fabrics that comprise in at least some sections multiple layers, especially one-piece woven (OPW) airbags comprising single-layer, double-layer and multi-layer sections. According to the inventive method, weaves or weave combinations are produced in the double- or multi-layer sections that are different from the plain weave.

An epitaxial growth process for producing a thick III-N layer, wherein III denotes at least one element of group III of the periodic table of elements, is disclosed, wherein a thick III-N layer is deposited above a substrate. The substrate can also be a template comprising the foreign substrate and at least one thin III-N intermediate layer. The surface quality is improved by a reduction of the N / III ratio and / or the reactor pressure towards the end of the epitaxial growth process.

The invention is concerned with control of a continuously variable vehicle transmission. The transmission in question is to have a variator (10) which is coupled between a rotary transmission input (32) and a rotary transmission output (46), to provide continuous variation in a transmission dive ratio, via a launch device such as a clutch (62; 68). The variator and the launch device are constructed and arranged to exert a required torque, defined by an input signal. In accordance with the invention, the same control signal is used to control both the variator torque and the torque capacity of the launch device. In such an arrangement, vehicle launch (i.e. moving away from rest) can be controlled in a straightforward manner by progressively raising the relevant control signal, preferably a hydraulic pressure signal. Further independent claims are including for applying traction load to races (20, 22) of the variator and for a method setting torque of the launch device (62; 68) higher than torque of the variator (10).

A luggage case (100) which may include a plurality of walls (102, 104, 106, 108, 110, 112) collectively defining an exterior structure (105) of the luggage case (100), additional a wheel bracket (134) mounted to and extending from one of said walls (102, 104, 106, 108, 110, 112) and a wheel (132, 232, 332). The wheel bracket may include first and second elongate arms (150, 152, 250, 252, 350, 352) extending along a common side of the wheel. The first and second elongated arms may be vertically spaced relative to each other over at least a portion of the length of the first and second elongated arms. The construction of the wheel brackets may result in improved shock absorption and reduced wheel noise relative to conventional wheel brackets and provide an improvement and alternative to conventional luggage wheel brackets.
