Abstract: A building kit for vertically or horizontally slidable windows which includes a multiple-chambered blind frame profile member fashioned of a synthetic resinous material which is identical for all four sides of the windows and sash profiles of hollow synthetic resinous material which are identical for all four sides of the window as well as an optional horizontal running track. The blind frame profile is fashioned so as to be planar on a side facing the sash except for approximately a centrally arranged projecting guide tongue strip extending in the longitudinal direction of the blind frame profile. An open undercut guide groove is provided in the blind frame profile member followed on each side of the chamber. To seal the sash along the corresponding inside of the window the blind frame is connected with a U-shaped end profile of a synthetic resinous material which is at most half of the width of the blind frame.

Abstract: A frame element, especially for window and door construction, which is formed as a composite member with a hollow metallic profile member covered by a sheath of synthetic resinous material. The sheath includes mounting lugs and grooves for directly supporting window or door members. The hollow metal profile is provided with outer flanges formed as extensions of side walls of the member, which flanges serve to provide a rigid support base for supporting the loads applied to the frame element by way of the sheath. Interlocking groove and strip connections are provided on the sheath and the profile member at the corners formed respectively between the outer flanges and the immediately adjacent joining side wall of the profile member. These interlocking groove and strip connections assure an elastic, resilient seating of the plastic sheath against the outer confines of the profile member over the entire surface of the profile member.

Abstract: A stabilized bi-elastic fabric bonded on its underside to an elastomeric, gas-tight film adapted for use in covering upholstered furniture. The fabric is formed from a ply yarn of elastomeric filaments, coarse yarn, and fine yarn. After being woven, the fabric is stabilized by a process involving steam shrinking, washing, drying and fixing. The stabilized fabric is then heat bonded to the film which makes the composite fabric well suited for filling with foam or for vacuum deep drawing.
