Abstract: A disposable diaper (10) is disclosed in which the elastic (24) which provides elasticized leg cuffs extends along substantially the entire length of each of the longitudinal edge portions (25) of the diaper between fastening means (30,32) on front and rear waist portions (20, 22 resp.) for fastening the diaper around a wearer.

Abstract: A rotary piston internal combustion engine includes a housing defining a cylinder chamber in the form of a circular ring. An even number of pistons circulate in the piston chamber and are of a circular cross-section adapted to the cylinder chamber. Two piston carriers mounted rotatably about the axis of the cylinder chamber each carry half the number of pistons, the peripheral surfaces of the piston carriers being such that they supplement the internal surface of the cylinder chamber to constitute a circular cross-section which corresponds to the pistons and against which piston rings on the pistons seal. At least one sealing ring is accommodated between the piston carriers and between each piston carrier and an oppositely disposed wall of the housing in an annular groove of the housing or a piston carrier respectively. The sealing ring bears against a co-operating surface of the respective piston carrier under a force which acts out of the annular groove.

Abstract: A disposable diaper in which elastic which provides elasticized leg cuffs is accommodated in a pocket of material formed by either a facing sheet or a backing sheet of the diaper. The pocket extends along each longitudinal edge portion of the diaper. Fastening member for fastening the diaper around a wearer are affixed to the diaper between the facing sheet and the backing sheet.

Abstract: An absorbent article, particularly a diaper, has a central absorbent unit (1) which is comprised of an elongated absorbent body (2) enclosed between a liquid-permeable inner casing sheet (3) which lies proximal to the wearer in use, and a liquid-impermeable, outer casing sheet (4) which lies distal from the wearer in use. The absorbent unit is provided along its longitudinal edges (9) with liquid-impermeable folds (6) which are upstanding from the inner casing sheet and which form side-leakage barriers. The article has a side-flap (18) on each side of the absorbent unit (1). The side-flaps (18), optionally with associated edge (21, 23), are produced in the form of rectangular strips (10) completely separated from the absorbent unit (1) and are thereafter jointed thereto. A longitudinally extending edge-part (13) of each strip (10) is suitably folded double and the backwardly fold part (19) is joined to the outer casing sheet (3a, 4b or 4) of the absorbent unit (1)along a curved fastening line (21).

Abstract: A lobed rotor machine including an annular cylinder chamber having inlet and outlet openings, four working pistons movable in pairs in the cylinder chamber, two piston carriers for supporting respective pairs of the working cylinder and rotatable about a common machine axis and displaceable relative to each other, and guide channels formed inside of each of the two piston carriers and defining supply channels and return channels for communicating cooling medium to the pistons.

Abstract: A male incontinence guard includes an inner, liquid permeable casing layer; an outer, liquid impermeable casing layer; an absorbent pad having a first end and enclosed between said layers so as to include a first side edge on one side of said pad and a second side edge on an opposite side of said pad; said absorbent pad narrows at the first end; a first elastic device attached in a prestretched state to the inner casing layer and extends from the first end along at least a part of said first side edge; and a second elastic device attached in a prestretched state to the inner casing layer and extends from the first end along at least a part of said second side edge; said elastic devices arranged such that contraction of said elastic devices causes said inner casing layer at the first end of said pad to take a concave shape and said outer casing layer at said first end of said pad to take a convex shape.

Abstract: An absorbent article intended for use as a urine-collecting insert in a diaper or an incontinence guard includes an inner casing layer (2) of liquid permeable material, which when the article is worn lies nearest the body of the wearer, an outer liquid permeable casing layer (3) and an absorbent pad (4) located between the casing layers. The outer casing layer (3) has a lower liquid permeability than the inner casing layer (2), such that liquid absorbed by the article is able to pass through the outer casing layer and absorbed by the diaper or incontinence guard, relatively slowly and in a controlled fashion.

Abstract: A disposable absorbent article, such as a diaper or an incontinence guard, includes an inner liquid-permeable casing sheet which is positioned nearest the body of the wearer when the article is worn, an outer liquid-permeable casing sheet, and an absorbent pad enclosed between the inner and outer casing sheets. The absorbent pad includes, at least in the crotch part of the article, a hose-like body that is comprised of a shape-stable material having a very high liquid permeability. The hose-like body is generally centrally positioned in the article and extends in the longitudinal direction of the article. The hose-like body borders on the inner casing sheet and is surrounded by absorbent material on at least the side thereof remote from the inner casing sheet. The article can also include liquid barriers positioned on respective sides of the hose-like body.

Abstract: The present invention relates to a disposable absorbent article, such as a diaper or an incontinence guard, which includes an inner liquid-permeable casing sheet (1), which lies the closest to the wearer's body when the article is in use, an outer liquid-impermeable casing sheet (2), and an absorbent body (3) which is enclosed between the two casing sheets. According to the invention, the absorbent pad (3) includes, at least in the region thereof which forms the crotch part when the article is worn, a hose-like body (5) which is made of a shape-stable material and which is highly permeable to liquid. The hose-like body is positioned centrally and extends in the longitudinal direction of the article and borders on the inner casing layer and is surrounded by absorbent material (4, 6) at least on the side thereof remote from the inner casing sheet.

Abstract: A disposable absorbent article, such as a diaper, an incontinence guard or the like, includes an inner, liquid-permeable casing sheet, which when the article is worn lies nearest the body of the wearer, an outer, liquid-impermeable casing sheet, an absorbent pad enclosed between the two casing sheets, and a layer of fibre wadding disposed between the absorbent pad and the inner casing sheet. The inner casing sheet is joined to the absorbent pad along two longitudinal lines forming permanent fold lines which divide the article, over at least a part thereof, into a central elongated part and two edge-parts located symmetrically on respective sides of the central elongated part. Each edge-part is folded between the respective fold line and its lateral edge such as to form an inwardly upstanding longitudinal fold in the outer casing sheet.
