A procedure for shutting down an operating fuel cell system includes disconnecting the primary electricity using device and stopping the flow of hydrogen containing fuel to the anode, followed by quickly displacing the residual hydrogen with air by blowing air through the anode fuel flow field. A sufficiently fast purging of the anode flow field with air eliminates the need for purging with an inert gas such as nitrogen.

Hand-holdable toy light tube comprising a handle, a light source and a tube of color shifting film. The light source is preferably disposed within an end of the handle. The tube of color shifting film extends from the end of the handle. During use, light from the light source interacts with the tube of color shifting film, producing a brilliant colored effect. Movement of the handle and thus of the tube of color shifting film produces multiple colors.

A system microscopy system and method that enable obtaining high resolution 3D images in a single shot are presented. The system is an ultra-high speed, real time multi wavelength phase shift interference microscopy system that uses three synchronized color CCD cameras. Each CCD is equipped with a precision achromatic phase mask which in turn allows obtaining π/2 phase shifted signals in three different wavelengths simultaneously.

The invention relates to a rail arrangement for coupling a displaceable element to a support structure, wherein the rail arrangement comprises a guiding rail and a fitting. In this arrangement the fitting is connectable to the displaceable element, and the guiding rail is connectable to the support structure. The fitting is arranged in the guiding rail in such a way that the fitting can be displaced in longitudinal direction of the guiding rail; wherein the guiding rail is formed as an open-top hollow profile with a rail base. In this arrangement the rail base comprises at least one elevation that extends upwards (i.e. towards the open-top). The fitting comprises a bottom surface which in longitudinal direction is interrupted by a continuous groove, wherein the form of the groove of the fitting is designed in such a way that the fitting is guided by the elevation along the guiding rail.

A clutch arrangement has a clutch device with a clutch housing capable of rotating around an axis of rotation, where the clutch device is designed to establish or to separate a working connection between a drive and a take-off and is provided with clutch components in the form of a piston and clutch elements. The piston produces a seal between a pressure space and a cooling space holding the clutch elements. The pressure space or the cooling space is connected to a supply unit so that it can be supplied with fluid medium, by connecting at least one supply line of the clutch device is connected to an infeed line of a gearbox and possibly by connecting at least one discharge line of the clutch device is connected to an outfeed line of the gearbox. An actuating line for a first supply line is assigned to the clutch device. The first supply line is independent of the infeed line for a second supply line or of the outfeed line for a discharge line.

A new fishing net 10 that has a handle 12, a looped portion 14, a net 16 attached to the looped portion 14, an elastic cord 18 that has a first segment 34 that extends from the handle 12 to an apex region 28 of the net 16, and a cord engagement means 20 that is located on the handle 12 and through which the cord 18 slidably passes to define a second segment 36 of the cord 18. The cord engagement means 20 frictionally engaging the cord 18 to allow the cord 18 to be incrementally extended in length between the handle 12 and the net 16 by exerting tension thereon in the first segment 34 and allowing the cord 18 to be retracted in length by exerting a tension thereon in the second segment 36.
