A medical dressing (10) comprising an embossed, thin polymeric film coated (11) on one side with a medical grade, pressure-sensitive adhesive (16). The embossed film (11) has a low coefficient of friction, preferably less than about 0.6, on the outer adhesive free surface which makes the film particularly resistant to unintentional removal by rubbing forces. The film is intended primarily for use ...

The invention relates to a method of monitoring the drilling of a boreho le through an earth formation with a rotating drill bit fixed at the lower end of a drillstring. At least one physical quantity associated with the vibrations resulting from the interaction of the rotating drill bit with the earth formation is detected and an oscillatory signal is generated in response thereto. Filt er coeffi...

Disclosed are rigid polyurethane-polyiso-cyanurate foams prepared from polyisocyanates, polyols, trimer catalysts and a blowing agent mixture comprising (i) a halocarbon, and (ii) an organic carboxylic acid, and, optionally water. The foams have excellent aged K-factor values at fluorocarbon levels reduced by up to 75 percent over prior art materials. 37,338-F

F 35356 Tubular Membrane A method of producing a membrane having substantially uniform porosity in which a blend of a first polymer and a second, immiscible, polymer is extruded to form a structure of the desired cross section in which the polymers are present as interpenetrating networks and leaching out the second polymer so producing a structure comprising the first polymer network characterise...

QM 35355 MICROPOROUS MEMBRANES A liquid phase-inversion process for the preparation of a microporous membrane from a solution in a latent solvent and a flexible microporous membrane comprising a highly crystalline aromatic polymer bearing in-chain ether or thioether and ketone linkage's described.

A cap comprising of a cover (2) and a tubular body (1) for use on a aerosol can (5). The tubular body (1), fitted onto the aerosol can (5), contains a perpendicular bar (10), horizontal bar (6), ducts (30) to release the contents on the can. To activate the ejection valve stem (14), a lever mechanism is incorporated in the cover which can be disposed in an open and close position. In the open posi...

A method for producing a laminate having at least one pleated lamina is disclosed. The method uses an apparatus having two rolls (22, 24) defining a nip, with at least one of the two rolls having circumferentially oriented grooves (26). The laminae (14, 16) are forwarded through the rolls in face to face relation. One lamina is pleated and the pleats are transversely registered with the circumfere...

STABILIZATION OF ANALYTES A method for stabilizing analytes with antibodies and antibody fragments comprises dissolving the analyte in a liquid to form a solution, adding analyte-specific antibodies, fragments of such antibodies, or both to the solution, heating the solution, and then cooling and filtering the solution. The filtered solution may be diluted in a suitable matrix.

Procédé d'introduction d'un opercule à coulissement étanche dans un corps tubulaire cylindrique et dispositif correspondant. Dans le procédé qui consiste à introduire un opercule à l'aide d'un moyen de poussée appuyant sur la face envers de l'opercule, on appuie le moyen de poussée de façon à obtenir un pliage de l'opercule lorsque la pression de l'air emprisonné dans la corps augmente, cet air s'...

In the process to texturise a filament yarn, the false twists are imposed at a point where the yarn material leaves the heating stage. The yarn with its raised bulk is given a temporary false twist during the thermal fixing action. The false twister is placed where the yarn leaves the heater unit so that the yarn is given a false twist passing through the heater. The pneumatic processing stage has...
