Abstract: A breathing tube which is designed for channelling inspiratory and/or expiratory breathing gas during at least partial artificial respiration of a patient, defines a virtual breathing-gas-flow path, which is imagined to pass centrally through the tube and along which the breathing tube channels the breathing gas. The breathing tube has a filter carrier in which is formed a filter-accommodating space, which has the breathing-gas-flow path passing through it and in which a breathing-gas filter, which can have breathing gas flowing through it, can be accommodated in an interchangeable manner. The filter carrier has a wall which encloses the filter-accommodating space at a radial distance from the virtual breathing-gas-flow path and has an introduction opening, which is arranged at a radial distance from the virtual breathing-gas-flow path and through which the breathing-gas filter can be introduced into the filter-accommodating space and can be moved into its operationally ready operating position.

Abstract: In a method of making multi-component plastic molded parts, using an apparatus which includes two outer platens with first half-molds, and a middle platen with second half-molds interacting with the first half-molds such as to define cavities in two parting planes for injection of a plastic melt and/or a PUR mixture, one of the first and second half-molds can move in increments relative to the other one of the first and second half-molds, thereby forming different cavities in the parting planes from cycle to cycle. In a first cycle preforms are produced in respective cavities and then held in one of the first and second half-molds as the other one of the first and second half-molds moves in increments. Further components can then be injected into cavities formed in the parting planes from cycle to cycle, while another process step can be executed from cycle to cycle in free half-molds.

Abstract: In a method for producing a composite, a carrier component is placed into an opened cavity of a mold. The mold is then closed to a predetermined position, thereby creating a cavity of a first expanded size. To improve venting, a vacuum is generated in the expanded cavity before filling the expanded cavity with a flooding material. A compression step is then executed either at the same time as flooding material is introduced or following the introduction of the flooding material.

Abstract: In a method for producing a coated composite component, an injection-molded part is produced in a first cycle by introducing a melt into the cavity of a first mold. A polyurethane layer is then applied to the cavity surface of an open polyurethane mold half. The mold half with the injection molded part produced in the first cycle is associated with the polyurethane mold half, and the so formed second mold is closed. The polyurethane layer is pressed or embossed onto the injection-molded part in the second mold, and the coated injection-molded part is removed once the second mold has been opened.

Abstract: A device for producing a plastic part that has a plurality of components includes a closing unit for receiving at least one mold in which a thermoplastic molded body can be shaped or positioned, and at least one polyurethane unit for introducing a polyurethane material into a larger cavity comprising the thermoplastic molded body. At least one additional polyurethane unit is provided for introducing an additional polyurethane material having different product properties into a same or a different, larger cavity. As an alternative, the at least one polyurethane unit can be adapted for an additional polyurethane material having different product properties for introduction into the same or a different, larger cavity.

Abstract: In a method for producing a coated thermoplastic material, thermoplastic material is fed into a twin-screw extruder to produce a homogenous melt as the thermoplastic material is advanced. While the melt is in plastic state an adhesion promoter for a coating material to be applied later or a small amount of a coating material to be applied later as adhesion promoter is added to the melt which is then transferred to an injection mold and allowed to cure to form a thermoplastic body. The thermoplastic body is then coated with the coating material.

Abstract: An integrated system for production of composites includes at least one polyurethane unit with a mixing head for mixing a polyol component and an isocyanate component, at least one plasticizing and injection unit, which is suitable for the melting and subsequent injection of a thermoplastic material, and one clamping unit to receive at least one mold. The plasticizing and injection unit and the polyurethane unit can each introduce material to be processed into a mold cavity within the clamping unit. In order to implement a unitary strategy of control and regulation and a unitary approach to operation of this type of integrated system apparatus, a single central control unit and at least one common supply device are provided, with the central control unit being connected at least with the at least one supply device. The at least one common supply device acts at least on both the polyurethane unit and the plasticizing and injection unit.
