Abstract:
The invention resides in a body-fluid absorption article which comprises at least two elongated and substantially flat members which, in use of the article, are relatively superimposed with opposed flat surfaces, said members being physically separated throughout, or over a substantial portion of, their interface. The article is further characterized in that its inner member, i.e., the member adapted to be worn next to the skin, mainly consists of a liquid-absorbent material, whereas its outer member comprises one or a plurality of fluid-barrier layers of a watersoluble polymer, such as carboxy-methyl cellulose, capable of preventing any passage of body fluids, at least for the time of use of the article.
Abstract:
In oxidizing sulphides contained in alkaline aqueous solutions by an oxygen-containing gas, the unwanted production of hydrogen sulphide is prevented by effecting the oxidation in the presence of finely divided active carbon and with vigorous stirring.
Abstract:
A tampon is disclosed for taking up menstrual fluids having as the main portion thereof a dry folded sheet material which is muff- or hose-shaped. The tampon is constricted and pulling means are attached at the point of constriction. The sheet material has an inner layer of absorbent fibrous material with relatively weak internal cohesion. A thin cover layer with relatively strong internal cohesion is used to prevent release of inner layer fibers. The configuration aids in insertion and the materials give good characteristics during use.
Abstract:
An apparatus for lifting (or, otherwise handling) objects, involving a plurality of movable contact members spatially arranged on a longitudinally extendible control element in which control element is movably connected with one or more transverse link mechanisms. According to the invention, each transverse link mechanism is comprised of an extensible and constrictable element, (e.g., a lazy tong mechanism) which is supported by a carriage in the lifting device, in turn, is provided with mountings for the control elements which carry and adjust suction cups in the longitudinal direction so that the longitudinal adjustment of the control elements (and thereby of the suction cups) is accomplished by means of movement of the carriage relative to the lifting device or another carriage. The adjustment of the suction cups in the transverse direction is accomplished by extension or constriction of the transverse link mechanism to increase or decrease the spacing of the control elements.
Abstract:
A METHOD FOR HANDLING LOADS COMPRISING THE STEPS OF SUBSTANTIALLY ENCLOSING THE LOAD WITH A BANDLIKE PACKAGING MATERIAL HAVING AT LEAST ONE VERTICALLY DIRECTED LOOP, CONNECTING FORCE-TRANSMITTING ELEMENTS TO OPPOSITE SIDES OF THE LOAD ADJACENT THE UPPER SURFACE THEREOF, AND APPLYING LIFTING FORCES TO THESE ELEMENTS.
