There is provided an absorption pad having a C-shaped cross section and a superabsorbent layer embedded therein, said pad being blunted at its forward and rearward ends in the nature of a truncated pyramid. In a process for the manufacture of the absorption pad, the absorption pad blanks are shaped on a flake wheel and subsequently finished as absorption pads by pressing and folding. Prior to the ...

An article having an absorbent pad assembly. The pad assembly has a pair of side edges, a longitudinally extending central panel, a pair of doubled longitudinally extending back panels underlying the central panel, and a pair of longitudinally extending top panels extending from the back panels and overlying the central panel.

A filter material, particularly for tobacco-smoke filters, comprises fibrillated polyolefin sheet having main generally longitudinally-extending strands interconnected by interconnecting strands and having a substantial number of free ends formed by severing main strands and/or strands which would otherwise have constituted interconnecting strands, the strands having a thickness in the range 5 mic...

In a procedure for processing suspensions of finely divided solid particles, the suspension, to remove a part of its liquid, is passed in turbulent flow over the surface of a microfiltration membrane under the influence of elevated pressure and with part of the liquid being filtered off until a solid/liquid ratio is achieved at which the suspension is reusable. In a preferred apparatus for carryin...

An auxiliary absorbent article for use atop a primary absorbent article such as a diaper, said auxiliary absorbent article comprising an upper facing layer, a superabsorbent layer and an undersurface, said superabsorbent layer comprising a superabsorbent material dispersed at a matrix such that fluid passes through said auxiliary absorbent article and may be absorbed by the primary absorbent artic...

A device for terminating the rotary movement of a driven shaft following an adjustable predetermined number of revolutions, with one or more switch disks arranged coaxially adjacent and provided with notches of their outer circumference, said disks being driveable by the shaft, with a plurality of switch disks with different rotational speeds, and with a switch arm resting on the outer circumferen...

Adhesion of two silicon nitride parts is accomplished by interposing a layer of calcium fluoride or a mixture of calcium fluoride with kaoline between the two silicon nitride parts and heating the resultant interposed layer.

A composition of at least one member selected from the group consisting of sodium fluoride and calcium fluoride and optionally containing kaolin is powerful adhesive for ceramic articles which is used by interposing the adhesive intimately between the opposed surfaces for union of the ceramic articles and heating the adhesive to a temperature equal to or higher than the decomposition temperature o...

This invention relates to electro-optical sensing of form type and other defects on surfaces such as sheet metal or plastic panels. Method and apparatus are disclosed for detection and quantification of defects such as dents, creases, low spots, flat spots, etc. which are a result of the manufacturing, material handling and assembly process. Surfaces of interest are generally those of automobile b...

A noise reducing cover for an internal combustion engine, comprising a layer formed of a material which is high in damping capacity, and metal fibers contained in the high damping capacity material, thereby effectively preventing engine noise emission, maintaining good heat conductivity therethrough.

In a sunshade blind for a door or window opening with a number of identical slats (10) which are arranged above one another and movable in the vertical direction, elastic connecting webs (18, 19) are arranged between each two neighbouring slats (10), each connecting web (18, 19) being fastened to both slats (10). This arrangement makes it possible to accommodate the blind in an extremely small spa...

The invention relates to roller shutters or roller shutter profiles, which are manufactured from light-permeable and heat radiation-permeable and possibly also from transparent material and in order that the known protective effect can also be used during the day. The visual protection which is lacking at night is achieved by combining these roller shutters with known measures such as curtains or ...

The invention relates to a roller shutter strip which is composed of two separate parts (half shells) (1, 2), one part of which consists of metal and the other part of a heat-insulating material and is shaped and dimensioned in such a manner that, after assembly of the roller shutter armour, one of its side surfaces is formed exclusively by the heat-insulating material.

Finely divided or vaporized organic and inorganic tin compounds are conventionally applied to heated glass articles to produce a coating of stannic oxide on the article. Superior coatings are obtained when the tin compound is butyltin trichloride. This compound offers the additional advantage of being recoverable in substantially pure form.

An insulated electrical cable uses an insulator comprised of an ethylene-vinyl acetate copolymer and an ethylene- alpha -olefin copolymer having a density of 0.91 or more. An insulated electrical cable also uses as an insulator a cross-linked composition made of an ethylene-vinyl acetate copolymer and an ethylene- alpha -olefin copolymer.
