Abstract: A tube connector for an infusion tube is connectable to an infusion container. The tube connector has a first fluid opening that is connectable to the infusion tube or to a drip chamber connected to the infusion tube to provide a first fluid connection between the infusion container and the infusion tube. The tube connector has a second fluid opening connectable to the infusion tube to provide a second fluid connection between the infusion container and the infusion tube. The tube connector has a blocking device configured to block a fluid connection between the infusion tube connected to the second fluid opening and the infusion container connected to the tube connector to prevent a release of fluid from the infusion container into the infusion tube.

Abstract: A coupling system for a closed fluid transfer system includes a coupling member that features a coupling member housing. The coupling member housing includes a housing portion that at least partially surrounds a sealing member receptacle in an axial direction with respect to the longitudinal axis and which includes a coupling member housing threaded portion on the inner surface facing the sealing member. The coupling system also includes a mating coupling member for coupling with the coupling member. The mating coupling member includes a mating coupling member housing that has a mating coupling member guiding structure. The coupling member housing threaded portion of the coupling member is configured such that the mating coupling member guiding structure and the sealing member receptacle structure are jointly and movably guided, in particular in a predetermined positional relation to each other, by the coupling member housing threaded portion.

Abstract: An adapter for coupling with medical vials has a housing with a center longitudinal axis. The adapter includes first latching portions on an inner circumference for latching to a first closing cover of a first vial, and second latching portions on the inner circumference for latching to a second closing cover of a second vial. The second closing cover has a larger diameter than the first closing cover. The housing has web portions and spring arm portions extending between the web portions and on which the first latching portions are arranged. The housing is elastically deformable from a first state, in which the spring arm portions latch with the first latching cover, into a second state, in which the spring arm portions allow a latching connection between the second latching portions and the second closing cover. The adapter device can be used in infusion therapy.

Abstract: A power-limit protection circuit with an efuse element. The power-limit protection circuit has an efuse element coupled between a first terminal and a second terminal. The power-limit protection circuit judges whether a calculated power signal defined from a current signal flowing through the efuse element and a voltage signal at a terminal of the efuse element is larger than a predetermined power threshold. When the calculated power signal is larger than the predetermined power threshold, the power-limit protection circuit increases an impedance of the efuse element to limit the current signal between the first terminal and the second terminal such that the power delivered through the efuse element is limited within the predetermined power threshold.

Abstract: A composition useful as an impregnant for the making of laminates for printed wiring boards including an epoxy resin a first cross-linking agent of a strene-maleic anhydride copolymer and a second co-cross-linking agent.

Abstract: A resin composition that may be applied to make laminates and printed wiring boards. The composition includes a copolymer of styrene and maleic anhydride (SMA) as a cross-linking agent, and a mixture of an epoxy resin and a bismaleimide triazine resin.

Abstract: A water-vapor-permeable, watertight, heat-reflecting flat composite is made by a process of combining a metal layer and a nonporous, water-vapor-permeable, watertight, hydrophilic flat substrate. The process includes at least the three steps of (1) selecting the substrate, (2) pre-cleaning the substrate, and (3) applying the substrate to the metal layer. Such a composite offers protection from heat loss, infrared-based detection, ultraviolet radiation, electro-smog, and static electricity.

Abstract: A piston for internal combustion engines, preferably made from aluminum alloy, has machined, oil-dragging grooves formed on the periphery of the piston skirt and concave transitions with a sawtoothlike profile with an obtuse profile angle. The piston skirt is provided with an electrodeposited hard iron layer having a thickness of 1-30 .mu.m and contains 0.5-6% metal-oxy compounds incorporated therein.
