Abstract: A polyamide moulding composition with particularly good tensile strain at break consisting of the following constituents: (A) 50 to 100% by weight of at least one transparent polyamide composed of: (a1) 55 to 77 mol % of acyclic, aliphatic diamine having 5-10 carbon atoms; (a2) 23 to 45 mol % of cycloaliphatic diamine having 6-36 C atoms, where the proportions of (a1) and (a2) are based on the entirety of the diamines used; (a3) 40 to 80 mol % of aromatic dicarboxylic acid or a mixture of such dicarboxylic acids; and (a4) 20 to 60 mol % of acyclic, aliphatic dicarboxylic acid having 8 to 16 carbon atoms, or a mixture of such dicarboxylic acids, where the proportions of (a3) and (a4) are based on the entirety of the dicarboxylic acids used; and (B) 0-50% by weight of additives,; where the entirety of components (A) and (B) gives 100% by weight.

Abstract: The invention relates to a method for storage and for transport of polyamide granulate which comprises at least one amorphous or microcrystalline polyamide. By means of this novel method, yellowing during further processing to form the moulded article can be avoided or at least reduced. Likewise, the invention relates to a corresponding container in which the polyamide granulate is stored. The invention also relates to correspondingly stored or transported polyamide granulate and also moulded articles produced therefrom.

Abstract: The present invention relates to a method and a device for detecting electrical energy delivered to an electric vehicle. To this end, the following steps are provided: connecting the electric vehicle to a charging station for obtaining electrical energy provided on a charging cable, feeding the desired energy quantity into a battery of the electric vehicle during a desired charging period, detecting of at least one electrical value required for the calculation of the energy quantity by an energy quantity meter and output of the at least one electrical value, required by the energy quantity meter for the calculation of the energy quantity, to a monitoring device for the operational monitoring of the charging station.

Abstract: A gas sensor with a housing (1, 11) has an optical signal transmission to the environment of the gas sensor (10). At least one light-emitting diode (3) is arranged in the housing (1, 11) on the inner side of a disk (4) that is transparent to light. At least one optical light guide (5), for coupling in the light of the light-emitting diode (3), is arranged in the housing (1, 11) on the outer side of the disk (4) that is transparent to light. The optical light guide (5) extends up to the outer surface (6) of the housing (1, 11).

Abstract: A vacuum cleaner has a vacuum cleaner housing and an exchangeable filter with through opening arranged in the housing. A holding arm connected with its upper end to the vacuum cleaner housing penetrates the through opening. A fastening member is detachably connected to the lower end of the holding arm for securing the filter to the holding arm. The lower end of the holding arm has a radial recess, and the fastening member has engagement elements engaging the radial recess when the filter is secured on the holding arm. The engagement elements block removal of the fastening member from the lower end of the holding arm. The fasting member has an actuating ring moveable between a locked position, in which the engagement elements secure the fastening member against removal from the holding arm, and a release position, in which the fastening member is removable from the holding arm.
