2083388 9117816 PCTABS00008 The invention relates to a process for the high yield, cost efficient means of separating enantiomers. The process utilizes a supported liquid membrane and a chiral carrier which selectively complexes with one of the two enantiomeric optical configurations (Fig. 1). The invention is also directed to an apparatus adaptable to the continuous and staged separation of enant...

Compositions characterized by a non-isocyanate based thermoplastic polymer and a finely divided isocyanate based thermoset polymer are disclosed. The compositions can optionally further include an adhesive thermoplastic compatibilizing agent. Finely divided scrap isocyanate based thermoset polymer materials such as polyurethanes, can be used in preparing these compositions, thus lowering manufactu...

Methods for achieving therapeutic treatment of diseases and for regulating gene expression in biological experimental sys- tems via modification or removal of the 5' Cap stricture of targeted ribonucleic acids are disclosed. Modification or removal of the 5' Cap structure is achieved in accordance with preferred embodiments utilizing antisense compounds which are complemen- tary to the 5' terminus...

TITLE OF THE INVENTION APPARATUS FOR JOINING ENDS OF MATERIAL WEBS TO EACH OTHER The ends of material webs or tapes are joined to each other in an apparatus in which two holding and press-on heads are tiltable about fixed journal axes away from two fixed guide rollers for the webs so that a slide carriage for the heads and for the fixed guide rollers is avoided. The holding and press-on heads a...

Method for high-rate charging of batteries with sealed cells, whereby through supplied charging current the efficiency the single battery cell is actively influenced such that the charging time and temperature rise of the cell is minimized such that in a first step the battery is discharged to a voltage UB slightly higher than a first reference voltage (UO) whereafter in a first recharging step th...

A foam is provided for use in a subterranean oil-bearing formation for reducing and controlling the mobility of a gaseous drive fluid. The foam is generated using an inert gas and a fluorocarbon surfactant solution in admixture with an amphoteric or anionic hydrocarbon surfactant solution. A relatively small amount of the fluorocarbon surfactant is operative, when mixed with the hydrocarbon surfac...

For measuring an angle of incidence of a luminous beam, one employs a polarized luminous beam which is brought to pass through a birefringent plate followed by an analysing polarizer, in order to obtain a succession of fringes of interference, and one analyses by means of an appropriate detector and an electronic circuit the spacings between the crests of said fringes, said spacings being a direct...

An adhesive having a content of a thermically curable oxazene resin which contains at least one 1-oxa-3-aza tetraline group in the molecule, optionally in combination with at least one curable epoxy compound, is used for bonding polyimide films to films of the same kind or to other substrates, particularly metal foils. Such bondings are highly heat-resistant and have an excellent peeling resistanc...

The set of devices which is the subject of the invention is for applications in the nautical sector; it consists principally of the integral sail mast-boom-sail assembly which can be oriented around 360 degrees, moved directly or by means of reduction gears. The assembly can be disassemblable or in a single piece. The system makes it possible to manoeuvre, orient and block sails, even of a large...

The fitting for connecting two parts of a dental prosthesis consists of a part (5) with a vertical plate (9) for connection to the side of a tooth, and an interlocking part (7) which supports an adjacent tooth. The first part has an arm (11) extending at right angles, with a tapered plug (13) supported vertically at its free end. The second part is hollow, with a rounded intermediate section (21) ...

Numerically controlled working unit (3; 5) for machines for working the end regions of constructional elements for furniture and the like, having a head (25; 27) which carries at least two tools (31, 33; 37, 39) with parallel axes, of which the first (31; 37) is movable along two translation and working axes (X, Y), whereas the second (33; 39) is movable along three translation and working axes (X...

The machine that opens and cuts textile fibres that are bundled or unpacked and unpacked material in general, to then be sent on for more work, includes: means of transportation with multiple pronged blades that alternate of a fixed bar with a holding mechanism; below this means of transportation a mobile bladed cutter, a rotating blade and a fixed stationary knife; and above the means of transpor...

Hair of straw or other handmade items are pulled together and tied more or less cut irregularly and so must be subjected to a hot immersion dying; these products are then dried and ironed
