摘要:
A connecting panel for joining communication components, the connecting panel having projections introduceable into pocket-shaped receptacles in the base of the communication components and being held in guides at the base. The connecting panel is designed essentially Y-shaped and has projections spacially offset relative to one another. These projections are at two arms that proceed parallel to one another and are joined to one another by a centrally located arm. A further arm proceeding perpendicularly relative to the centrally located arm has a projection proceeding in its longitudinal axis. The guides provided at the base are in the form of ribs having a T-shaped cross section.
摘要:
The invention relates to a heating device, in particular for mobile use, comprising a combustion chamber for reacting fuel with combustion air in order to release heat, a heat exchanger for transferring at least part of the released heat to a heating medium to be heated, a fuel conveying device for supplying fuel to the combustion chamber, a combustion air fan for supplying combustion air to the combustion chamber, a heating medium fan for supplying the heating medium to the heat exchanger, a common drive for the combustion air fan and the heating medium fan, at least one sensor for monitoring the mass flow of the heating medium, and a controller, which controls the fuel conveying device and the common drive. The controller is designed to change the ratio of the amount of the heating medium and the amount of the fuel supplied to the combustion chamber according to the mass flow of the heating medium.

The present invention relates to a process for preparing β-ketonitriles of the general formula I in which R1 is, inter alia, C1-C12-alkyl, C2-C12-alkenyl, C2-C12-alkinyl, C3-C8-cycloalkyl, C3-C8-cycloalkyl-C1-C4-alkyl, phenyl-C1-C4-alkyl, phenoxy-C1-C4-alkyl or benzyloxy-C1-C4-alkyl; R2 is, inter alia, hydrogen, C1-C12-alkyl, C2-C12-alkenyl, C2-C12-alkinyl, C3-C8-cycloalkyl, C3-C8-cycloalkyl-C1-C4-alkyl, phenyl, phenyl-C1-C4-alkyl, phenoxy-C1-C4-alkyl or benzyloxy-C1-C4-alkyl, which comprises reacting a nitrile of the formula II in which R1 has one of the meanings given above with a carboxylic ester of the formula III in which R2 has one of the meanings given above and R3 is C1-C12-alkyl, C1-C4-alkoxy-C1-C4-alkyl, C3-C8-cycloalkyl, C3-C8-cycloalkyl-C1-C4-alkyl, phenyl-C1-C4-alkyl, phenoxy-C1-C4-alkyl or benzyloxy-C1-C4-alkyl, where the reaction is carried out in the presence of a potassium alkoxide and at least 80% of the nitrile of the formula II are added to the reaction under reaction conditions.
摘要:
A throttle valve (10), in particular for injecting a fluid into a geological formation, is described, which comprises a valve body (10) having a piston chamber (11), an annular piston (20) having a fluid channel (21), which extends from a high-pressure side (H) to a low-pressure side (L) of the throttle valve, with the annular piston (20) being displaceable within the piston chamber (11) and the fluid channel (21) being transmissive or closed depending on the position of the annular piston (20) in the piston chamber (11), and a cover plate (12) which is provided on the high-pressure side of the valve body (10) and through which the fluid channel (21) protrudes from the high-pressure side piston chamber (11), wherein the fluid channel (21) is closed in axial direction with a sealing disk (22) which can be rested tightly on the cover plate (12) on the high-pressure side, and the fluid channel (21) has a radial throttle opening (23) adjacent to the sealing disk (22). A fluid injection device having such a throttle valve is also described.
