  • Patent number: 6830699
    Abstract: A method and a device for the restriction of blooms of micro-organisms in an aqueous system are described. A smaller portion of the body of water in the system is subjected to a radiation treatment, preferably a UV-treatment, whereupon the treated quantity of water is returned to the aqueous system. The UV radiation will induce activation of latent viruses, and when these are returned to the water system, micro-organisms in this system will be killed or inactivated, and new micro-organisms will not be formed.

  • Patent number: 6830293
    Abstract: The seat pad as a free-standing structure which provides a seat and back. A pair of contoured rigid bars are enclosed within opposite sides of a fabric sleeve to shape the sleeve into a seat and back. In addition, a web of densified padding is disposed between the bars and within the fabric sleeve to bias the rigid bars outwardly of each other to flatten the sleeve. Rows of stitching are employed to secure the padding to the fabric to provide not only reinforcement but also a pleasing aesthetic appearance to the seat pad.

  • Patent number: 6820799
    Abstract: A single blank is used to make an expandable envelope construction having four side edges which can expand as the envelope construction is filled to capacity. The blank is provided with horizontal and vertical score lines and fold lines which permit the sides and bottom of the construction to collapse inwardly while the pocket enlarges in thickness and decreases in height and width. The blank has side flaps with corners at the ends which are overlaid by the back panel and closure panel in an unsecured manner to maintain the envelope in a sealed condition when expanded.

  • Patent number: 6811545
    Abstract: The safety needle employs a manually operable actuator that can be depressed into a housing in order to release a spring-biased slider that carries a hollow needle. Upon release, the slider moves into a position to retract the needle over a blunt cannula so that the blunt cannula protects against cutting by the needle. An actuator guard may also be employed to prevent inadvertent actuation of the actuator.

  • Patent number: 6786002
    Abstract: The floatable planter is employed in a body of water, such as a fish pond, in order to prevent the growth of algae. The planter employs an aquatic pot for receiving a plant, a peat pot having a planting medium for receiving the aquatic pot, a floatation ring about the aquatic pot, a mass of decomposable material selected from the group consisting of barley straw and lavender, and a mesh bag that envelopes the pots, floatation ring and decomposable material. As the decomposable material decomposes, hydrogen peroxide is produced in order to act as an algaecide in the body of water. The floatation ring ensures the proper floatation of the straw or lavender in the water.

  • Patent number: 6782736
    Abstract: A method for measuring interface levels between fluids is described, characterized in that, with the aid of a magnetic field forming means, a variable magnetic field is formed in one of the fluids whereby a counterflowing magnetic field is established, being a function of the fluid properties with respect to the portion of conducting fraction in the fluid, and conductivity of the fraction; and the properties of the mentioned fluid are registered by registering the dominating impedance, alternatively resonance frequency, of the system; and by corresponding registrations of different fluid layers at the respective height levels, and in the existing interphase layers, and thereafter by mutual comparison of the mentioned properties, one or more exsisting multiphase levels are determined. A device to carry out the method is also described.

  • Patent number: 6761706
    Abstract: A plastic needle guard is mounted on a hub in which a needle is secured. In order to cover the end of the needle, the needle guard is slid manually off the hub and over the end of the needle to position the needle end within the guard. A washer that is loosely mounted within the guard and through which the needle passes drops off the end of the needle to block any return movement of the needle out of the guard. Other embodiments use lock-type washers to prevent a return movement of the needle.

  • Patent number: 6758213
    Abstract: The drinking device for a diver can be mounted in a helmet or in a hollow-nasal mask mounted on the helmet. The drinking device includes a supply line which can be connected to a mouth piece within the helmet or mask to supply liquid under a slight pressure. In addition, a stopper arrangement is provided for regulating a flow of liquid through the supply line to the mouth piece. This stopper arrangement may be controlled manually by the diver.

  • Patent number: 6758267
    Abstract: There is referred to a process for retrieving equipment (70, 72, 90) which is stuck, from a bore hole, where the equipment is connected to a tool and is brought to the surface, and the method is characterised in that a tool is lowered in the bore hole, such as mounted to the lower end of a string or the like, said tool comprising a stationary grip part (14, 44) which is arranged substantially enclosingly about the equipment residue (70, 72, 90) between its outer wall and the wall of the bore hole, after which a central axially movable grip part (16) of the tool is caused to be forced downwards for fixing the equipment residue against the stationary grip part. There is also disclosed a device for accomplishing the method.

  • Patent number: 6748893
    Abstract: There is disclosed a foil system for hydrofoil vessels, where the foil system lifts and carries the total weight of the craft at speed, and comprising a number of adjustable control fins/-surfaces (3-5), supporting legs (7-9) between the foil system and the hull of the vessel, and means to adjust the control fins/-surfaces. The foil system is characterized in that it is formed by one single approximately horizontal foil body comprising two generally mirror symmetric foil arms (1, 2) which extend aft to each side in almost equal angle, in that the forward corner of the angle lies in the center line (11) of the craft, and the foil arms extend aft to each side in an almost equal angle (12) with the longitudinal centerline (11) of the craft.
