  • Publication number: 20240162690
    Abstract: A solid state power switch assembly of an aircraft solid state power controller includes a circuit board, at least one solid state power switch, and a busbar. The at least one solid state power switch has a first side and an opposing second side. A power switch electric contact surface is formed on the first side and the at least one solid state power switch is arranged on the circuit board with the second side facing the circuit board and the first side facing away from the circuit board. The busbar comprises at least one busbar contact portion configured for electrically contacting the power switch electric contact surface and at least one busbar mounting portion, which is configured for be mounted to the circuit board, so that the at least one solid state power switch is sandwiched between the at least one busbar contact portion and the circuit board.

  • Publication number: 20080220031
    Abstract: The present invention relates to dermocosmetic compositions comprising a compound comprising the structural element of the formula I where the radical Z has the following meaning: H, C1-C22alkyl group, C6-C10-aryl group, C1-C22-alkoxy group or a C6-C10-O-aryl group substituted by a C1-C22-alkyl or C-C22-alkoxy group, and the radicals R1 to R6, independently of one another, have the following meaning: H, C1-C22-alkyl group, C6-C10-aryl group, O, OH, C1-C22-alkoxy group or a C6-C10-O-aryl group substituted by a C1-C22-alkyl or C1-C22-alkoxy group, it being possible for R5 and R6 to be bridged in such a way that a five- to eight-membered ring is formed and, in the case of a five-membered ring, this ring may be part of an oligomer as a result of covalent bonds at positions 3 and 4. The invention furthermore relates to the use of said compounds in dermocosmetic formulations and the use of the dermocosmetics according to the invention for reducing skin or hair damage caused by free radicals.
