Abstract: A fire rated door with a surrounding door frame, consisting of a glass pane, which is embedded between its circumferential metal frame, said fire rated door consists of at least one door leaf realized from two glass panes spaced apart by means of profiles, whereby the glass panes extend almost as far as to the border of the door leaf and a transparent fire protection material is included between the spaced glass panes.

Abstract: One preferred embodiment of an improved concrete anchor designed in accordance with the present invention for embedment in a concrete panel or the like includes an elongated bar having substantially flat parallel faces, an inner end disposed within the panel, an outer end disposed within a recess in the surface of the concrete panel and side edges extending between the faces. The side edges extend in continuously diverging relationship from adjacent the outer end to adjacent the inner end. In accordance with another embodiment, the preferred concrete anchor includes an elongated bar having substantially flat parallel faces; an inner end disposed within the panel; an outer end disposed within a recess in the surface of the concrete panel; and side edges, preferably substantially straight, which extend in a substantially parallel relationship between the faces. The outer end includes spaced, outwardly-projecting extensions disposed adjacent the side edges of the bar and, preferably, an elongated opening.

Abstract: A portable pop-up self-supporting of tent-like form comprising a pair of hinged side members (A) and (B) each consisting of a flexible sheet having a peripheral coilable frame. The two side members are hinged along adjacent edges and the opposed edges are joined by flexible base sheet (C). The triangular ends of the tent may be closed by a flexible material including an access flap if required. The base of the tent is held apart by a removable and separate panel member (D) also consisting of a flexible panel having a peripheral coilable semi-rigid frame. The entire structure comprising the side members and the separate base member may be coiled into overlaying loops for storage and, is self-erecting when released.
