Abstract: Arrangement at gutters in roofs for slope to the sides of the gutters, which have outlets in the form of sinks and spouts. The object of the invention is to produce a gutter of the aforesaid kind, which renders it possible to assemble a gutter corresponding to the special roof requirements with respect to the number of sinks, overflows etc. and to provide a gutter, which can be repaired without therefore requiring the entire gutter to be dismantled. The invention further renders possible an accurate horizontal positioning irrespective of possible differences in height in the carrying structure or the roof. Differences in height in this context are to be understood to refer to the small variations possibly prevailing in height position from one truss to the other and lying within permissible construction tolerances. The invention further ensures by simple means the prevention of ice formation at the gutter edges. The invention implies that at least one section (1) at the outer edge of the roof (outer section) is provided with at least one sink (6) having its inlet in the same plane as the bottom (2) of the section, a first outflow (8) connected to a second sink (7), and a second overflow (10) of higher location connected to a spout (9).

Abstract: In the packaging field certain types of packages are manufactured from pre-shaped, cylindrical casings made from a heat-shrinkable laminate. The casings are formed by winding a material sheet around a mandrel and subsequent sealing together of the overlapping ends of the sheet. However, because of the stiffness of the material the leading end of the sheet protrudes tangentially from the mandrel during the winding and prevents an accurate adaptation of the material sheet to the surface of the mandrel. According to the method and arrangement of this invention this disadvantage is avoided in that the leading end of the sheet is pre-heated on the side facing the mandrel to such a degree, that the shrinking is initialled. The shrinking of one side only results in that the leading end of the material sheet is given a curved shape with a radius that coincides with the radius of the mandrel, and consequently the leading end is no longer an obstacle to the winding.

Abstract: Speed limiting in an ignition system utilizing a magneto generator is accomplished by increasing the damping of the half wave not utilized for ignition. This is accomplished by switching in additional resistance in parallel with the damping circuit resistance when the speed of the engine exceeds the speed to which it is to be limited. The additional damping during the half wave which is not utilized causes a decrease in the current and voltage wave utilized for ignition because of armature reaction. The decrease, in turn, causes a sudden change in ignition timing in the direction of late ignition and therefore an additional damping or complete suppression of ignition.
