Abstract: A bracket for fixing a prefabricated window to roof boards or sheathing in an inclined roof is already secured to the window main frame during the factory assembling of the window. The presecuring of the bracket is effected by a screw inserted through a hole in a positioning member which through a connecting portion consisting of a bridge and a rodlike member is integrally connected with one side edge of a first leg of the bracket. The first leg continues at its lower side into a second leg at right angle to the first leg. Before packaging the window for transportation the first and second legs are swung into abutment on the main frame by turning around the connecting portion. When the window is to be installed in the roof the first and second legs are swung through an angle of 180.degree. until the first leg abuts against the positioning member. In this position mounting screws are through the overlapping holes screwed into the main frame.

Abstract: A manually-operated pump element of a device for artificial respiration of uman beings. The pump element includes a gas tight, elastomeric, self-expanding and preferably elongated hollow body, as well as two connecting pieces which respectively serve as an air-inlet and air-exit opening. Two indentations are integrated into the wall of the hollow body as grasping aids. With reference to the cross section of the hollow body, the indentations are separated from one another by an angle of 100.degree. to 140.degree.. In order to apply artificial respiration to a person, the hollow body is grasped with one hand at the indentations in such a way that the palm of the hand and the fingers span the periphery of the hollow body by approximately either 120.degree. or 240.degree., as a result of which, when the hollow body is compressed with this hand, approximately one third or two thirds of the hollow body is emptied.
