  • Patent number: 7122021
    Abstract: An eye rinsing device including a flask that contains an eye rinsing liquid and that is sealed by a closure element that projects up from the future opening of the flask. The flask includes an eye cup and is adapted to co-act with a flask holder. The eye cup is situated around the closure element and a sleeve surrounds the eye cup. The sleeve is non-rotatably affixed in the closure element. After the flask has been opened, by twisting the sleeve relative to the flask, it is difficult to return the flask to the holder.

  • Patent number: 6314604
    Abstract: The present invention relates to a support (2) for a paintbrush (1). The support (2) may advantageously be used both when you want to lay down the paint brush on a flat surface and when you want to hang the brush on a bucket. The support (2) consists of an integrated part of the paint brush (1), projecting from the paintbrush in the form of a projection from the paintbrush body. According to the invention, the projection comprises at least two points of support, allowing the paintbrush to rest on these points of support, together with a point of support provided by the paintbrush somewhere along the handle (3). Preferably, the support is located at the head (4) of the paintbrush, at the shoulder (6) of the head (4) close to the handle (3). Furthermore, the support may comprise an arched flange (8), directed along the handle, which can function as a bucket holder.

  • Patent number: 4008623
    Abstract: A gyroscopic instrument which may be a compass includes a hollow sphere enclosing at least one motor-driven gyroscope and floating in an electrically conductive liquid within the inner surface of revolution of a vessel surrounding the sphere at a distance therefrom providing for a gap therebetween. A motor-driven pump circulates the liquid through an inlet of the vessel, through the gap, through an outlet of the vessel and through a passageway back to the pump. The surfaces confining the gap have pairs of opposite conductive electrode portions for conducting electrical energy to the motor-driven gyroscope or gyroscopes. The liquid circulating through the gap exerts a bearing pressure on the sphere holding it spaced from the inner surface of the vessel. For this purpose the gap has a relatively narrow bearing zone communicating with the inlet and a relatively wider zone communicating with the outlet.
