  • Aqueous pearlescing concentrates
    Patent number: 6210659
    Abstract: A pearlescent concentrate containing: (a) from 30 to 80% by weight of an alkyl ether sulfatef; (b) from 5 to 20% by weight of a surfactant selected from the group consisting of a betaine, an alkyl and/or alkenyl oligoglycoside, and mixtures thereof; and (c) from 1 to 10% by weight of an (oligo)ethylene glycol mono- and/or difatty acid ester, all weights being based on the total weight of the composition, and wherein the concentrate is polyol-free.

  • Flashing light warning apparatus
    Patent number: 5162703
    Abstract: A flashing light warning apparatus, which includes a voltage source (U), a main gate transformer (HW), a flash tube (R), an ignition device (Z), at least one storage condenser (K), and an electrical switching device (S), can be switched to provide light energy for daytime flashes and nighttime flashes in an uncomplicated, cost effective system which produces dependable light flashes. The night flashes have a light energy such that they can be seen from afar only with night vision apparatus. When the switching device turns off voltage production of the main gate transformer or further transmission of voltage from the at least one storage condenser, the ignition device is coupled to an auxiliary gate transformer (ZW) for carrying out light flash production by means of high frequency ignition voltage produced by the ignition device.
