A pencil that includes a polymer-bonded lead, a polymerbonded wood substitute material that includes an organic filler and covers or surrounds the lead along its length, and an adhesion promoter layer disposed between the lead and the wood substitute material. The lead and the wood substitute material each have a polymer. The polymer in the lead being incompatible with the polymer in the wood substitute material so that the polymer of the lead and the polymer of the wood substitute material do not create any connection with one another. The adhesion promoter layer is connected to the polymer in the lead and to the polymer in the wood substitute material so that the adhesion promoter layer forms a connection with the polymer in the lead and with the polymer of the substitute material. The organic filler is formed by particles having a maximum particle size of 250 μm.

In order to control the brightness and/or the color of a projection apparatus (1), more particularly of a rear projection apparatus of a projection wall, wherein the image generation is based on time-sequential mixing of primary colors, it is proposed that a semi-transparent mirror (14) is used to couple out a portion of the light supplied to the imaging device (11), that a sensor (15) is used to measure said light portion and that the image generation is controlled with the signal thus obtained.

A wall saw includes a saw head which is displaceable longitudinally on a running rail and has a swivelable saw arm and a saw blade with cutting elements which is detachably fastened to the saw arm. The saw blade is rotatable by means of a drive unit which is mounted on the saw arm and which communicates with a drive arrangement. The saw blade is fastened to the saw arm via a coupling formed of two flange halves (11,17) which slide one inside the other and which can be connected with one another in a detachable manner, one flange half (11) being fastened to the flat side of the saw blade facing the saw arm and the second flange half (17) being arranged at the saw arm.

摘要:
A pressure control valve serves to regulate the fuel pressure in a fuel system. The pressure control valve includes a valve housing, at least one inlet, at least one outlet, and at least one prestressed, electrically actuatable, and at least regionally ball-shaped valve member. The valve member cooperates with a valve seat structurally connected to the housing. To make it possible to achieve stable closed- and/or open-loop control properties of the pressure control valve, it is proposed that the valve seat widen conically toward the valve member, and the ball diameter of the valve member is selected such that with the valve closed, the valve member touches the valve seat in the vicinity of its farther end.
