  • Patent number: 6572277
    Abstract: In a plug arrangement for optical waveguides, there is mounted on the end of the cable accommodating the optical waveguide a cable fixing sleeve that is bonded to the outside of the cable. The ends of the plastic fibers of the optical waveguide cladding are brought out of the cable end and laid back onto the external surface of the bonded-on cable fixing sleeve and a further sleeve being pushed onto said cable fixing sleeve, with the plastic fibers of the optical waveguide cladding being clamped and bonded between the two sleeves.

  • Patent number: 5402705
    Abstract: Control device (1) for an electrical household appliance for the preparation of infusion beverages, having a housing (2) enclosing a reservoir (3) for cold water, a heating plate (4) supported an infusion collector (5), a water heater (6) connected thermally to the plate (4) and having a conduit (6') connected to the cold water reservoir (3) and a rising conduit (6") connected to a water pipe (7) of an infusion filter (8) disposed above the infusion collector (5). An electrical heating resistance (9) for the water heater (6) is connected to an electrical supply circuit (10) switchingly controlled by the device. The device supplies the electrical resistance (9) in a first phase intermittently by current pulses of predetermined duration, separated by pause times also of predetermined duration, and in a second phase supplies the electrical resistance (9) with a direct current.

  • Patent number: 4812407
    Abstract: The system for testing the diffusion behavior of a substance comprises a donor compartment detachably mounted on a holding member of a rotor, rotatably around a vertical axis, said donor compartment being bounded at its bottom by a membrane effective to separate the donor compartment from an acceptor compartment. The membrane comprises a flexible carrier of a bio-compatible, lifeless, light permeable material, on which cells constituting a monocellular layer have been cultivated, for example. By determining the time dependent variation of the quantity of a substance passing through the membrane by diffusion, it is possible to determine the coefficient of diffusion and/or the coefficient of permeability of the membrane and of the cell culture provided thereon. By suitable selection of the cells, conditions may be created that closely resemble those that occur during the absorption of the respective substance through the biophase of a living organism.
