An electrical switch for an electric device is provided, including a contact system including at least one electrical power supply line, an electronic control circuit and an electrical connection element arranged between at least one contact face of the control circuit and the power supply line. The electrical connection element has at least one metal pin that is fixed in an electrically non-conductive fixing element such that the pin is aligned with respect to the contact face and the power supply line, and such that the pin protrudes from the fixing element on both sides thereof to contact the contact face and the power supply line.

The invention relates to a four-row tapered roller bearing for machine mountings, with an inner ring of two-part design axially and on outer ring of single- or multi-part design axially, with an inner and/or an outer tapered-roller row, being supported in each case by an inner ring part. In order, firstly, to confer a large supporting width on the bearing and, secondly, to ensure as optimum as possible and as uniform as possible a loading of the rolling bodies in the form of the tapered rollers, the tapered-roller rows are arranged in an O-arrangement, and the roller axles or the respectively adjacent outer and inner tapered rollers of the two respectively adjacent outer and inner tapered-roller rows are arranged at an inclination in such a manner that those lines of influence of the tapered rollers which characterize the pressure angles intersect in the region of the axis of rotation of the tapered roller bearing. In addition to other advantages, this bearing can be produced more cost-effectively and, with regard to production quality, more reliably than known four-row tapered roller bearings.

A connector plug is described for connecting an ignition coil to a spark plug, comprising an electrical conductor, which has a first end for contacting the ignition coil and a second end for contacting the spark plug, and a protective tube, which surrounds the electrical conductor. In accordance with this disclosure it is proposed that the protective tube has a predetermined bending point with a reduced bending stiffness.

A valve device has a movement element, which is cylindrical at least in sections, and a guide element, which has a guide recess for guiding the movement element and is pressed into a valve housing. The guide element comprises a radially inner ring-like section and a radially outer ring-like section. The guide recess is arranged in the inner ring-like section. On its outer circumference, the outer ring-like section has a number of contact sections which are arranged distributed uniformly over the circumference and by means of which the outer ring-like section is pressed into the valve housing. The inner ring-like section is connected to the outer ring-like section via an identical number of connecting sections, which are arranged distributed uniformly in the circumferential direction, wherein, as viewed in the circumferential direction, the connecting sections are offset radially by an angle of 180 DEG/N in relation to the contact sections.

A spark plug includes: a center electrode, a ground electrode, which is side-mounted on the center electrode, and a noble metal insert, which is situated on the center electrode. The noble metal insert is situated in a cutout provided in a base material of the center electrode and connected in a continuous material to the base material of the center electrode. The noble metal insert is directed with one surface towards the side-mounted ground electrode.

A steam generating system includes a nozzle assembly for pulverized coal and air, the coal nozzle assembly comprises an inner housing (3) for conveying primary air and coal and an outer housing (5) for conveying secondary air to an exit face (13) of a nozzle tip (1), wherein the outer housing (3) and the inner housing (5) are arranged coaxially and limit a channel (15) for the secondary air, wherein the cross-sectional area (A_IH) of the inner housing (3) increases towards the exit face (13) of the nozzle tip (1), wherein the cross-sectional area (A_OH) of the outer housing (5) decreases towards the exit face (13), and wherein bars (11) are located in the inner housing (3) near the exit face (13) that accelerate the velocity of the primary air and coal particles.

The invention relates to a windscreen wiper device, in particular for a motor vehicle, comprising at least one shaft (13) that is mounted in a gear housing. The windscreen wiper devices that are known from prior art have gear housings that require a large amount of space. To provide a smaller gear housing, one end of the shaft or shafts (13) can be mounted in the gear housing (11) and the other end in a gear housing cover (12).
