  • Publication number: 20080287885
    Abstract: The invention relates to a cylinder/piston unit having a cylinder and a piston which is guided therein, wherein the cylinder and the piston enclose a chamber which can be filled at least for a time with an additive, and the cylinder has at least one exit element at its front end. Here, the cross section of the chamber or the cross section of the cylinder inner wall is increased at least in regions of the cylinder from the front to the back, wherein the cylinder end having the exit element is at the front. The piston has an elastic skirt at least in the front region, the front outer edge of said elastic skirt defining a cross-sectional area in the case of an unloaded piston, which is greater than an area which is defined by a contour line. The present invention develops a cylinder/piston unit which ensures simple and reliable handling and can be stored for a long time in the filled state, in a manner which is impervious to gas and moisture.

  • Publication number: 20080146997
    Abstract: A one-way injector having a housing in which at least one mechanical spring energy store, at least one piston/cylinder unit, which can be at least temporarily filled with an active substance, at least one piston-actuating plunger and at least one tripping unit are arranged. To this end, the spring energy store comprises a preloaded spring element. The spring element is held in the preloaded position by a tension means surrounding at least a region of the spring. The tripping unit comprises a cutting tool which, in order to release the energy of the spring energy store, severs or weakens the tension means at least one point, the weakening immediately tearing the tension means. With the present invention, a one-way injector is developed which, with a small overall size, has only a few components and ensures reliable mounting and functioning with simple manipulation.

  • Publication number: 20060288834
    Abstract: A device for manufacturing a product from strip tape includes a roll that draws off and separates a web of material. The web of material is severed into individual strips in cooperation with a multiple circular knife roll. A vacuum conveyor channel is associated with each strip. The vacuum conveyor channel is designed such that each strip is turned on its way to the channel or through the channel by about 90°. The end of the vacuum conveyor channel brings the strips together at one site to form a unit and at that site there are provided a guide and a transport device for the further transport to conversion equipment.
