  • Patent number: 7066185
    Abstract: The hairclip (1) has two legs (4, 5) and a hinge (6) with a spring (7) connecting the legs. The legs (4, 5) each have a tine base (10, 11) and a number of curved tines (8, 9) arranged in rows on one side of it. Each tine base (10, 11) is adjoined by an actuating section (12, 13) on the opposite side. The two actuating-sections (12, 13) are disposed asymmetrically relative to a length of the tine bases (10, 11) and opposite each other. For the sake of tight spacing and easy manipulation, these hairclips (1) are placed on the curlers (2) in such a way that the actuating leg sections (12, 13) of one hairclip (1) are not disposed in the immediate vicinity of the actuating leg sections (12, 13) of an adjacent hairclip (1).

  • Patent number: 7037488
    Abstract: A hair wax product is made by a process, in which a solid wax composition is heated to melt or soften it and then foamed with a gas in a mixer that applies shear energy to it. The gas is preferably air or a non-reactive gas, such as nitrogen. The gas is introduced to the liquified or softened solid wax composition in a sufficient amount so that the density of the resulting hair wax product is less than or equal to 0.9 g/ml, preferably 0.6 to 0.8 g/ml. The hair wax product contains bubbles and/or pores having a size of from 0.0001 to 5 mm and has melting and softening properties such that rubbing it by hand is sufficient to remove a waxy portion from it and work the waxy portion into hair.

  • Patent number: 7024778
    Abstract: The split end removing device (1) is a removable attachment (3) for a haircutting machine (2). This split end removing device includes first and second parallel hair strand guiding sections (4,5) and a third hair strand guiding section (6) removably positionable in a working position (A) between the first and second sections (4,5). The parallel sections (4,5,6) are formed so that a hair strand (7) placed under the first and second sections (4,5) is grasped from below by the third section (6) in its working position and the attachment (3) is held fixed on the haircutting machine (2) so that only split ends (9) are cut away from the hair strand. The third hair strand guiding section (6) is a separate part (10) that is completely removable from a remaining portion of the device (1). It has a handle section (12), comb teeth (13) and a parting tip (15).

  • Patent number: 7004782
    Abstract: The connecting device (1) for electrical connection of a socket (2) of an electrical apparatus (3) with a socket plug (4) of a power cord (5) includes a cord receptacle (19) provided with curved first and second receptacle sections (7, 8) on opposite sides of the socket (2). The curved first and second receptacle sections (7, 8) are dimensioned so that a power cord loop (9) wrapped around the socket plug (4) can be held fixed in a first seat (10) in the first receptacle section and in a second seat (11) in the second receptacle section of the cord receptacle (19). Because of that unintended interruption of electrical power supplied to the electrical apparatus by unintentionally pulling the socket plug of the power cord out of the socket of the electrical apparatus is avoided.
