  • Patent number: 10487423
    Abstract: A sensor yarn (10) having a thread core (11) around which first and second conductors (12, 13) are helically wound. The two conductors (12, 13) are electrically insulated from each other and from the thread core (11). The two conductors (12, 13) form a capacitive component (15) together with the thread core (11). In one embodiment, the sensor yarn (10a) has a capacitance (Cl) per unit of length that changes in the direction of extent (E) of the sensor yarn. This can be accomplished by a change in the winding geometry of the first or second conductors (12, 13) or by a change of the relative permittivity (E) of the sensor yarn (10). In another embodiment, the sensor yarn (10b) has photosensitive material (30) and a length change is effected by an incident to the light (L). As a result of a length change or other deformation of the sensor yarn (10a, 10b), the total capacitance (CG) of the sensor yarn (10a, 10b) changes, which can be determined by means of an evaluating unit (17).

  • Patent number: 8152857
    Abstract: A tension-free elastic tape is used for the surgical treatment of female urinary incontinence. The tape has a textile structure that allows ingrowth of the tape into the connective tissue. On its longitudinal edges, the tape has edge threads (2, 4, 6, 8) that project from the textile structure of the tape and that especially facilitate a good primary anchoring of the tape in the tissue. The edge threads are firmly incorporated in the structure of the tape.

  • Patent number: 8104392
    Abstract: The invention relates to a rod-shaped fiber composite material (400) composed of a matrix (412) and a circular braid (402) embedded into the matrix. To increase the stability of the fiber composite material (400) and also to perform ducting functions for electricity and fluids, the wall of the circular braid is provided with wall chambers (408) which are separated by a phase boundary from the matrix (412) of the fiber composite material (400). These wall chambers (408) lead to inner and outer sections of the wall of the circular braid (402) being spaced apart, which is useful for the stability with regard to flexing and torsional loading in particular. Rod-shaped fiber composite materials (400) according to the invention can be used for creating stable structural components as well as for producing efficiently protected ducts. The invention further relates to an apparatus and a process which are useful for producing fiber composite material according to the invention.

  • Patent number: 7709986
    Abstract: The invention relates to a direct drive for a cylinder of a converting machine, in particular a printing press or coating machine that converts sheet-type printed materials. The aim of the invention is to develop a direct drive for a cylinder of the afore-mentioned type in such a way that the required lateral corrections are significantly reduced. To this end, the direct drive includes a rotor (14) that is detachably mounted on the end of the cylinder (6, 10) and a stator (15) that is concentric with the rotor and is detachably fixed to the side frame (13). A register motor (16), which is fixed to the frame, is coupled to gearing (17, 18) and this gearing (17, 18) is coupled to a helical gear or screw drive (19, 2, 21, 22), which is in turn coupled to the cylinder (6, 10) by means of an axial/rotative coupling (23, 24).
