Abstract: In this ridge or hip covering, flexible sealing strips (9) are arranged between the covering caps (7) fastened to the ridge or hip board (6) of the roof structure and the roofing tiles (3).In order that the sealing strips (9) can universally be used with the most different roofing tiles and roof pitches, they comprise a flexible supporting strip (10) which is provided on one or both longitudinal edges (11) with a comblike edge part (12) of elastically deformable material, the teeth (12a) of which are connected with an edge strip (13) of flexible material which bridges the tooth spaces allowing the teeth to spread, whereby the outer longitudinal edge (14) of the edge strip adapts to the contour of the upper side of the roofing tiles (3) lying below it.If with the sealing strips (9) both a sealing against rain and driving snow and a ventilation of the roof space is to be made possible, an air-permeable bonded fabric, in particular of polyester or polyamide fibres, can be used for the edge strip (13).

Abstract: A closure assembly for a container includes a filler nipple formed on the container and having an inner wall provided with a depression, a plug unit and an operating lever pivotally supported on the plug unit, and a sealing ring received in a groove of the plug unit. The sealing ring has a radially outwardly expanded sealing state and a relaxed, non-sealing state. A sealing ring actuating device is operatively connected to the sealing ring and the operating lever for moving the sealing ring from one state to another upon movement of the operating lever between an intermediate position and a closed position. A locking bolt arrangement is supported in the plug unit and has an advanced, locking state and a withdrawn, unlocking state.

Abstract: An arcuate or circular profile element of generally V-shaped cross-section has a curved bottom wall, arcuate sidewalls having free edges, and laterally projecting flanges projecting from the free edges. By choosing specific relationships between the thickness of the different parts of the element, lighter-weight elements can be used to withstand the same loads as before, or elements having the same weight as before can be used to support heavier loads.

Abstract: A piston for internal combustion engines, preferably made from aluminum alloy, has machined, oil-dragging grooves formed on the periphery of the piston skirt and concave transitions with a sawtoothlike profile with an obtuse profile angle. The piston skirt is provided with an electrodeposited hard iron layer having a thickness of 1-30 .mu.m and contains 0.5-6% metal-oxy compounds incorporated therein.

Abstract: A stack of sheets is stood on a support surface inclined to the horizontal by 15.degree. at the upstream end of a track. A pair of elements perpendicular to this surface and mounted on a carriage clamp this stack and the carriage is displaced to the opposite end of the track. An applicator brush underneath the track in its center is rotated about an axis perpendicular to the track and parallel to the support surface. This brush is partially immersed in a hot-glue bath so that on rotation it may stroke a layer of glue on the bottom of the stack held in the clamp on the carriage.
