Cladding elements, such as tiles, plaques, wall panels, wall paper, vinyl covered cloth and the like are attached to or mounted on structural elements such as lath, sheet rock, and the like, by a method which includes providing cladding and structural elements with a receiving layer, positioning between the receiving layers a gripping member having a plurality of stiff gripping elements, the receiving layers being adapted to permit the gripping elements to penetrate and lodge therein, and pressi...

A filter element primarily for disc filters and comprising a pair of moulded panels secured together in parallel relationship so as to define between them a cavity, each panel having on its outer surface a series of outstanding spaced parallel supporting ribs, drainage perforations through the panels between the ribs thereon, and a drainage outlet from the cavity between the panels.

Annular, linear, and point contact structures are described which exhibit a greatly reduced susceptibility to process deviations caused by lithographic and deposition variations than does a conventional circular contact plug. In one embodiment, a standard conductive material such as carbon or titanium nitride is used to form the contact. In an alternative embodiment, a memory material itself is used to form the contact. These contact structures may be made by various processes, including chemica...

The invention discloses a trace element solution, which comprises at least one metal selected from the group comprising selenium, copper, zinc, manganese and chromium and which comprises a concentration of the metal(s) of at least 60 mg/ml. The solution further comprises at least one compound selected from the group comprising iodine, potassium iodide, sodium iodide, iron, iron chloride, zinc oxide, manganese sulphate, sodium selenite, copper carbonate, sodium carbonate, anhydrous disodium EDTA ...

The invention relates to composite elements comprising the following layered structure: (i) 2 to 20 mm metal, (ii) 10 to 300 mm plastic, (iii) 2 to 20 mm metal, whereby (i) and/or (iii) optionally comprise a closable opening.

Compressive and tensile structural elements having an enclosure with walls surrounding a cavity. A non-compressible material is disposed in the cavity. The walls are shaped such that a force tending to compress or elongate the element by a first deflection causes an amplified second deflection of the walls into the non-compressible material. The second deflection exerts a compressive force against the non-compressible material, resulting in a resistance to the first deflection and the force tend...

A filter assembly comprises a tube plate supporting the open ends of a plurality of substantially tubular filter elements, the filter elements being provided in groups of three, the elements of each group being connected one to another in the group by three support strips, and the arrangement being such that any group of elements can be detached from the tube plate and replaced by the same or a replacement group without detaching or cutting away the other groups of elements from the tube plate.

The invention relates to optical elements comprised of an optical isotropic completely aromatic polyester with a glass transition temperature T.sub.g.gtoreq.180.degree. C.

A multielement resistor may be assembled into a matrix from a plurality of resistor elements (12) of a U shape construction. The elements (12) are suspended from their upper portions by connecting brackets (16) which are supported by a supporting frame (14). Connecting brackets are preferably of electrically conducting material and insulated from supporting frame (14). Power input/output brackets (18) are provided. The elements (12) are supported at their upper parts and hang from the frame (14)...

Thermographic elements comprising at least two layers, wherein: at least one of the layers comprises polymer, the polymer consisting essentially of, repeating, interpolymerized units derived from 9,9-bis-(4-hydroxyphenyl)-fluorene and isophthalic acid, terephthalic acid or blends thereof, the polymer being sufficiently low in oligomer content to allow formation of uniform film; and at least one of the layers is an imaging layer, selected from the group consisting of dye-donor layers, image-recei...
