Highly abrasion-resistant transfer coatings are provided on a wide variety of substrates, thermoplastic or thermosetting, by transfer coating from a mold surface or a flexible web, such as by use of a heat transfer tape, an ultra-thin coating consisting essentially of a non-resinous binder material such as microcrystalline cellulose together with mineral abrasive particles, preferably alumina or a...

Also included in the ski binding (7) fastening is an intermediary elastic component (4), and the upper footplate (3) is elastically rotatable around an axis parallel to that longitudinal of the ski body (2). To prevent transmission of vibrations from the ski to the binding (7) and to the foot of the user, the foot plate and binding are elastically and rotatably connected to the fixture plate (5) a...

Inspection of workpieces traveling along a production line includes on-line inspection of the workpieces at an upstream inspection station to detect possible flaws without interrupting the progression of workpieces along the production line. Possible flaws in the inspected workpieces are imaged, and images of possible flaws are stored in a memory in a way that associates a stored image with the wo...

There are described novel alpha -[4-(3'-fluoro-5'-halopyridyl-2'-oxy)-phenoxy]-propionic acid esters and -thioesters having a herbicidal action and an action reducing the growth of grasses, which compounds correspond to the formula I (I) wherein Q is oxygen or sulfur, Hal is halogen, and R is hydrogen, a metal cation, an ammonium group, an unsubstituted or substituted alkyl, cycloalkyl,...

Alkenes of the formula (I): in which R is C2-6 alkyl, n is 1, 2 or 3 and X, independent of other substituents X, is a specified substituent preferably chloro or fluoro, are prepared by reacting a compound of formula (III): with methylenetriphenylphosphorane or by dehydrating an alcohol of formula (V): especially by heating the alcohol (V) in the presence of an alumina catalyst...

An automatic shimming system for correcting inhomogeneties in magnetic resonance magnetic fields. The static magnetic field is mapped using three dimensional phantoms that comprise a plurality of samples including at least an element having non-zero nuclear magnetic moments spatially distributed to enable uniquely locating each sample with only two locating gradients.

Solid particles or viscous liquid droplets of core material (27) are encapsulated in a coating material (21) largely as single particles with a single coherent coating, by feeding a suspension of the two materials onto a rotating surface (13). The suspension is centrifugally dispersed by the rotating surface into relative large coated particles (27, 27a) and relatively small droplets (21a) of coat...

Compositions for flame proofing wood e.g. in the form of aqueous solutions containing tetrakis (hydroxymethyl) phosphonium salt, methylolmelamine with at least 3.5 optionally alkylated hydroxymethyl groups per melamine nucleus, a polyfunctional nitrogen compound with at least 2 N-H groups e.g. urea and a base e.g. triethanolamine.

Non-radioactive chemically-labeled polynucleotide probes, such as non-radioactive chemically-labeled, single-stranded DNA probes, are hybridized to fixed, denatured, single-stranded genetic material having a make-up complementary to said probes for determining the identification and/or presence of said genetic material. The non-radioactive chemical label on said probe is employed to elicit a respo...

A 2,2-difluoro-2-desoxycarbohydrate is used to prepare antiviral nucleosides.

A new process for the preparation of 6-deoxyanthracyclinones of general formula I: I wherein R represents a hydrogen atom, a hydroxy group or a lower alkoxy group is described. The process provides a total synthesis of the 6-deoxyanthracyclinones of formula I using 1,2,3,6-tetrahydro-phthalate as starting material. The obtained racemic mixture of the compounds of formula I, if desired, ...

The present invention relates to a device or kit and a method for the inhalation administration of gangliosides and inner ester ganglioside derivatives useful for the treatment of various nervous disorders, such as those resulting from accidents or diseases which have damaged the nervous tissue.

The invention relates to new cyclic ethers which are substituted in the alpha -position by an isocyanide-dichloride group, of the formula in which R1, R2, R3, R4, R5 and n have the meaning indicated in the description, and to a process for their preparation.
