  • Patent number: 8510168
    Abstract: A method of distributing hair care or cosmetic products where a salon owner, stylist or booth renter can procure hair care or cosmetic products including hair dyes from a vending device located within the salon as needed at the point of use. The transaction data representing the product purchased, identification of the purchaser, location of the vending device and like is transmitted to a central computer over a communications network. The central computer updates inventory data of the vending device based on the transaction data and if necessary, schedules delivery to the vending device based on the updated inventory data. Additionally, apart from inventory control, the transaction data can be used to follow fashion trends in the hair care and cosmetics fields.

  • Patent number: 8146782
    Abstract: Disclosed is a foam head (1) for a propellant container (2) with an inner and an outer crimped edge (3, 4) of a valve disk (5). Said foam head (1) comprises an actuating button (6) and a foam discharge port (7) and is embodied so as to sit directly on a valve stem (8). A bottom section (9) of the foam head (1) has an outer diameter (10) that is approximately identical to an inner diameter (11) of the inner crimped edge (3). An outer rib (13) which faces the actuating button (6) is disposed in a lower area (12) of the bottom section (9) so as to engage underneath a bottom side (14) of the inner crimped edge (3). A lower edge (15) of the bottom section (9) is provided with at least one recess (16) in order to form an annular spring (17).

  • Patent number: 8057677
    Abstract: A process is described for the extraction of one or more substances from a fluid starting material with an appropriate extraction agent by use of a static micromixer for mixing the starting material with the extraction agent. The static micromixer is provided with disk-shaped components, the disk (1) being provided with at least one inlet opening (2) for introducing at least one fluid stream into a linking channel (3) disposed in the plane of the disk and at least one outlet opening (4) for removing the fluid stream into a mixing zone (5) disposed in the plane of the disk, the inlet opening (2) being connected with the outlet opening (4) in a communicating manner through a linking channel (3) disposed in the plane of the disk, and the linking channel (3) before opening into the mixing zone (5) being divided by microstructure units (6) into two or more part channels (7), and the widths of the part channels being in the millimeter to submillimeter range and being smaller than the width of the mixing zone (5).
