摘要:
Methods, treatment compositions and treatment systems are disclosed for forming a detachable and renewable coating on a receptive surface by a process of applying a treatment composition comprising a plurality of hydrophobically modified fumed silica particles colloidally dispersed in a volatile solvent; allowing the volatile solvent to evaporate; and thereby depositing a protective coating on the receptive surface consisting of a layer of the hydrophobically modified particles, which provide a substantially transparent coating with dirt- and water-repellency properties that effectively shed dry particulate soils as well as water from the treated surface or treated article bearing a receptive surface. The methods, treatment compositions and treatment systems employing the hydrophobically modified fumed silica particle are particularly useful in providing nearly invisible detachable coatings and treated articles featuring surface protective benefits including dirt- and water-repellency, self-cleaning with water, and easier cleaning benefits when applied to a variety of automotive and home surfaces, both interior and exterior, including articles and materials such as metals, painted materials, sealed materials, plastics and polymeric articles, wood, textiles and the like.
摘要:
Process for producing detachable dirt- and water-repellent surface coatings on articles, wherein during the coating process, hydrophobic particles are applied to the surface of the articles, thus generating a surface structure with elevations on that surface of the articles that has dirt- and water-repellent properties, which comprises suspending the hydrophobic particles in a solution of a silicone wax in a highly volatile siloxane, and applying this suspension to at least one surface of an article, and then removing the highly volatile siloxane.

Solid odor absorbers including a solid carrier with a nanostructured surface and, incorporated therein, active zinc ricinoleate as an odor absorber are provided.
摘要:
A method for processing compositions, compositions obtained by such a process and methods of use are disclosed for forming a detachable and renewable protective coating which is substantially transparent. The inventive process compositions are produced by making a highly concentrated dispersion of hydrophobically modified silica particles in the presence of an optional, yet preferable, disilazane derivative under high shear conditions. These process compositions are intended to be further diluted to final treatment compositions, optionally while adding other functional ingredients.

An electromechanically driven digital indicating device comprising an arrangement of seven flaps electromagnetically movable to one of two defined positions. The flaps are disposed in a housing at one plane thereof so as to form an "8"-shaped figure. The device includes a deep drawn parallelopiped housing having a front window opening in the form of a parallelogram and having a plate with an elevated, freely accessible "8"-shaped contour constructed integrally with the housing. The plate is supported only at connecting rods at the rear of the housing in internal sides walls of the housing. On the reverse side of the bar-shaped contour, there are provided grooves into which bearing bolts of the flap elements are pivotally inserted.

摘要:
The invention relates to a gravity measurement apparatus comprising a torsion balance bearing a test mass. The torsion balance has a predetermined center of mass and is rotatable around a predetermined rotation axis, wherein the torsion balance is asymmetric in such a way that the center of mass of the torsion balance is offset to the rotation axis of the torsion balance.

摘要:
The feed line (7) and the return line (8) are combined to a single current supply line (6) at one end of the coil which leads to the first turn sections connected to the opposite end of the coil. Second turn sections running back to the supply line (6) are radially opposed from respective first turn sections.
摘要:
Apparatus for the detection and evaluation of process parameters arising during the remelting of an electrode (31) to a metallic block (32) in a vacuum arc furnace detects deviations of at least one process parameter from a predetermined course and uses them to locate faults in the electrode and/or in the metal block (32).
