Abstract: Wig or hairpiece having a flexible antislip system (2) which allows a user to non-adhesively and removably attach the wig or hairpiece to the user's head. The wig or hairpiece includes a drawable fabric (3) impregnated with a thin drawable film (4). The thin drawable film is arranged on a surface of the drawable fabric which contacts the skin of the user's head when the wig or hairpiece is positioned on the user's head. The thin drawable film prevents the wig or hairpiece from slipping on the user's head when positioned on the user's head. The thin drawable film has at least one of a non-sticky and a non-gummy antislip surface at temperatures lower than a softening temperature of the thin drawable film.

Abstract: An apparatus for spinning hollow bicomponent filaments. The apparatus includes a distributor, a spinneret having holes and a shim having openings fixed between the distributor plate and the spinneret. The distributor supplies a first polymer having an MV to a first part of the spinneret holes and a second polymer having a lower MV to a recessed section of the spinneret. The shim openings are positioned above the spinneret holes and extend away from the first part of the holes to allow the second polymer to flow from the recessed section, through the shim openings, to a second part of the spinneret holes. The two polymers travel along the opposed first and second parts of the holes until exiting the spinneret through respective asymmetric C-shaped apertures. The apertures are sized so that hydraulic split does not occur between the polymers and consequently potential filament kneeing is obviated. Upon exiting the apertures, the polymers self-join to form hollow filaments and are quenched.

Abstract: An injection device has a housing (50, 60) and therein a spring for storing energy for an injection operation. The spring (94) impinges, in the proximal direction, upon an ejection member (92) for ejecting injection liquid (16) from a vessel, displaceably arranged in the housing, at whose proximal end an injection needle is attached. Located in the housing is a displacement member (36), displaceable in the longitudinal direction, for displacing the vessel (14) in the proximal direction, in order to effect a movement of the injection needle (18) in the proximal direction and, thus, its insertion. Provided on the ejection member (92) is a detent lug (100), associated with which is a corresponding detent opening (102) in the displacement member (36). A control member (70), effective in travel-dependent fashion, serves to disengage the detent lug (100) from the detent opening (102) when the displacement member (36), during the injection operation, has traveled a predefined distance in the proximal direction.
