摘要:
The invention relates to a halogen incandescent lamp for motor vehicle headlamps with two incandescent filaments (21, 22), which are arranged within a lamp vessel (10), wherein a first incandescent filament (21) is designed for operation with a higher electrical power than the second incandescent filament (22), wherein the incandescent filaments (21, 22) are constructed in such a way that their dimensions and/or their geometry are in each case matched to an operating voltage of at least 20 volts, and at least the second incandescent filament (22) is an incandescent filament in the form of a single coil. Preferably, both incandescent filaments (21, 22) are in the form of incandescent filaments with a single coil, wherein the first incandescent filament (21) is used, for example, for producing the upper beam or lower beam and the second incandescent filament (22) is used for producing the daytime driving light or foglight.

In a method for laser drilling holes in a substrate, a laser beam is provided having a be spot diameter which is smaller than a diameter of a hole to be drilled. The laser beam is aligned to a new hole to be drilled, and a beam axis directed in a jump direction predefined by a starting position to a center of the hole to be drilled. The beam axis is directed in a defined radial traversing movement away from the center and onto a defined circular path. The angular direction of the traversing movement is defined as a function of the jump direction such that any change in direction of the beam axis at the center does not exceed a predefined maximum angle or else the direction is maintained.

The present invention relates to a process for the coating and water-repellent impregnation of mineral building materials, in which an architectural coating composition containing from 1 to 30 % by weight of C1-C20-alkyl-C1-C6-alkoxysilane as impregnating agent is applied to the building material. The principal architectural coating compositions are paints and plasters.

A controller has an axially releasable locking unit operable to prevent rotation of a regulating shaft from at least one locking position, without first axially moving the regulating shaft. This push-to-turn or pull-to-turn locking unit is arranged entirely outside of a housing of the controller, and is arranged with mounting particulars matched to those of the controller such that the same controller assembly can be used interchangeably either with a push-to-turn locking unit or without such a unit.

Transparent aqueous organopolysiloxane compositions comprising (A) a salt of a water-soluble organic or inorganic acid and a polysiloxane, which contains in addition to the other siloxane units siloxane units containing SiC-bonded monovalent radicals having basic nitrogen atoms in an amount of at least 0.5 percent by weight, based on the weight of the polysiloxane; and (B) an organic silicon compound having basic nitrogen atoms in an amount of from 0 to 0.5 percent by weight, based on the weight of the organic silicon compound; and when constituent (B) does not contain at least one organic silicon compound having a molecular weight greater than 600 g/mol in an amount of at least 0.1 part per part by weight of contituent (A), then an organic solvent (C) is present in an amount up to about 5 percent by weight based on the weight of constituent (A), in which the organic solvent is soluble in water up to about 1 part by weight per 100 parts by weight of water at 20.degree. C. and 1020 hPa (abs.) and is free of halogen atoms.The organopolysiloxanes may contain Si-bonded hydrogen as well as at least one SiC-bonded radical having a basic nitrogen atom in one and the same molecule.

A cooking and/or heat-maintaining unit comprises a main heating element and an auxiliary element adjacent thereto. A control therefor comprises a regulating or control device having a rotary setting member with a shaft for adjusting the power or temperature, as well as a switching member for switching an additional heating system on or off, the switching member having a switching shaft arranged coaxially with the shaft on the setting member. The switching member is operable by rotation of the setting member to a given angular setting, the setting member and switching member being independent until the angular setting is reached. The switching member preferably further comprises a quick-action switch with stable limiting positions, operable by the setting member, and which in one of the limiting positions operates a contact for switching the additional heating system on.
