Marker elements are arranged on or above the surface and mark the position relative to...

A method of determining the concentration of an analyte with the use of a bioelement comprises the steps of introducing into a chamber comprising a first and a second surface disposed opposite one another, a sample containing the analyte and a quantity of a bioelement selected for its ability to interact with the analyte bringing about a change in the chemical, physical and/or chemico-physical cha...

The invention discloses a process for the manufacture of porous cellulose particles, which have regular shape, and a capacity of sorbing 1.5-9 times of their own weight of water, a tap bulk density of less than 0.85 g/ml. The process for the manufacture of these porous cellulose matrices is performed by mechanically treatment of hydrolyzed cellulose in a wet stage. The cellulose matrices have pref...

For gas phase polymerization reactions in the presence of an unsupported polymerization catalyst, there is provided a process for introducing a liquid catalyst so as to provide a resin particle lean zone such that the average particle size of the resin produced ranges from 0.25 to 1.52 mm (0.01 to 0.06 inches).

The invention relates to a composition intended to be admixed to a moldable solution of cellulose in an aqueous tertiary amine oxide, which composition consists ofsolid particles,a mixture of a tertiary amine oxide and water, in which the solid particles are dispersed, andat least a further substance,with the proviso that the solid particles and said at least further substance are different from c...

A method for producing an elastomeric mixture based on the steps of mixing the additives and/or fillers of the predetermined composition of the mixture to be produced into a solution of at least one elastomer in one or more solvents, removing the solvent from the mixture thus obtained, and granulating the mixture to produce dry granules of elastomeric mixture.

An automatic transmission for a vehicle is improved by including torque control for the engine. The processor control for the transmission controls the torque converter and/or the automatic gearbox. The control also generates a target torque value for the engine and this is fed to the engine management system for optimum engine settings. The transmission control and the engine control have program...

In accordance with the present invention there is provided a method for making a highly radiopaque polyolefin compound, wherein the radiopaque material in said compound is substantially uniformly dispersed and held within a polymer matrix. During the m ethod one first heats an amount of polyolefin, preferably low density polyethylene, to at least its melting temperature. The amount of polyolefin i...

The invention relates to a hinge, used for example as a fitting on furniture or doors, comprising two connecting pieces (1, 2) rolling against each other, which are joined by at least two flexible joining elements (5, 6) which overlap the two connecting pieces (1, 2) in opposite directions. To ensure that the two connecting pieces (1, 2) can displace axially in relation to each other the invention...

An easily adhesive polyamide film has been created from unstretched or uniaxially stretched non-heated polyamide film coated with a water-base coating mixture, whose main constituents are (A) water polyurethane resin containing acetylene glycol in which two adjacent triple-bonded carbon atoms are replaced with a hydroxyl group and a methyl group and/or a non-ionic surface active agent which is an ...

A method and apparatus for nucleation and growth of diamond by hot-filament DC plasma deposition. The apparatus uses a resistively heated filament array for dissociating hydrogen in the reactant gas. For two sided diamond growth, configurations of substrate-hot filament-grid-hot filament-substrate or substrate-hot filament-hot filament-substrate configuration are used. For the latter configuration...
