Abstract: A method of fastening a button or the like to a garment such that the garment will be buttoned up after the fastening operation, wherein said button is composed of plastic and initially comprises a button head and a stem projecting from the button head, the stem having an outer end for piercing the garment and for deformation by ultrasonic vibration, a central section characterized by a substantially smooth profile, and an inner section flaring into the button head, the method comprising the steps of: providing a button hole in a first portion of the garment; placing said first garment portion in an overlying relation with a second portion of the garment; positioning said button such that the button head is disposed on the side of said first garment portion opposite to said second garment portion and such that the stem extends through the button hole and pierces at least partly through said second garment portion; and deforming the outer end of the stem by ultrasonic vibration thereof.

Abstract: Roof covering comprising a number of surface covering sheet metal strips and a number of fastening elements to be fastened to a foundation structure and to grip over the respective sheet metal strips and thereby hold them in place against the foundation structure. The surface covering sheet metal strips are highly profiled into a wave shape extending in the longitudinal direction of the strips with a wave length, which is of the same order as the width of each strip which has raised portions and countersunk portions as seen from the intended upper side of the strip and bent edge portions extending along the longitudinal edges of the strip. One bent edge portion has a portion extending in outwards direction from said upper side and preferably a subsequently following portion, which is parallel to the principal surface of the strip. The other edge portion has a portion extending in direction away from the principal surface and preferably is followed by a portion parallel to the principal surface.

Abstract: A receptacle for liquids, which has a portion with an opening and provided with a thread portion and a lid with a thread portion for engagement with the first said thread portion and a drawing off tube. This tube is displaceable between two positions, in one of which it extends from the opening portion into the interior of the receptacle. In the other position the tube extends from the opening portion and outwardly which is utilized in connection with drawing-off operations. The tube has a flange which is arranged in a resilient manner to change shape. It can be squeezed between an inner sealing surface of the lid and a sealing surface of the opening portion of the receptacle for liquids.

Abstract: The present invention relates to an apparatus for the feeding of buttons or similar objects to a processing station e.g., a fastening station. The apparatus comprises a rail arranged to receive a row of the buttons and debouch them at a processing station in which holding means are provided to hold the objects and alternatively release them. At the delivery end of the rail two holding elements are provided to allow the feeding of one of the buttons from the rail, catch the fed button and hold it in the processing station and release the button after the processing. According to the invention the holding elements each has the form of a section, rotatable into three positions around an axis. In the first position both the sections are placed opposite to the open delivery end of the rail allowing the feeding of one button from the rail. In the second position they are placed opposite to each other holding the button between the sections.
