  • Patent number: 10072686
    Abstract: The fastener is intended to be attached to a glazing element, which has a glass sheet and at least one frame part setting against the surface of the glass sheet. The fastener has a support part and a fastening element to be inserted into the gap between the glass sheet and frame. The fastening element comprises a locking element for locking to the surface of the frame part facing the glass sheet. The fastener installed in place remains in place in the gap between the frame part and glass sheet by means of the locking element without any other attachment elements. The locking element can be a locking projection turning to an angle from the plane of the fastening element, a flexible locking tongue turning to an angle from the plane of the fastening element or a rigid locking tip. The support part may comprise gripping means for attaching to the edge rail of the sunshade.

  • Publication number: 20160186487
    Abstract: In the method a sunshade is installed to a glazing part, which comprises a transparent sheet (10) with a first end edge and second end edge and a first side edge (16) and second side edge (18). The side edges are free edges of the sheet. In the method at least one first fastening element (20) is attached close to the first end edge of the transparent sheet and at least one second fastening element is attached close to the second end edge of the transparent sheet, and the sunshade (100 is suspended on the said fastening elements. The first and second fastening elements are attached to the side edges of the transparent sheet. Typically the sunshade can comprise at least one guide wire (24), which has a first end and second end. In this case the first end of the guide wire is attached to the first fastening element and the second end of the guide wire is attached to the second fastening element.

  • Patent number: 6444329
    Abstract: The present invention is related to a method of preserving plywood, particle board and similar wood composite products made from wood pieces/particles and a binder used to adhere such wood pieces/particle together against rot and mould decay. According to the invention, the preservative of the wood material is a complexing agent which is capable of binding transition group metals and is admixed into the binder used in the manufacture of said wood composite products prior to the formation of said product. The invention also concerns a binder composition, which contains a polymer resin as its adhesive component and a complexing agent, particularly an aminotetracarboxylic acid or a salt thereof, by approx. 1-30 wt.-% as the preservative of the wood material, and a method of producing said binder composition. Tests performed on faced plywood indicated that a water-soluble, environmentally safe complexing agent offers a white rot resistance which is superior to conventional preservatives commonly used today.

  • Patent number: 5428822
    Abstract: A radio system including at least one local exchange (MX); a radio network having fixed radio stations (BS) located apart from each other and connected to the local exchange; and at least one mobile radio station (MS) capable of roaming freely within the area of the radio network and informing the radio network of its location by selecting one of the fixed radio stations (BS) in accordance with a predetermined selection procedure and sending to the base station a registration message which is forwarded to the local exchange (MX). The mobile radio station (MS) provides the registration messages with information indicating the order of transmission of the messages, on the basis of which information the radio network determines the order of transmission of successive registration messages of the same mobile radio station.
