Patent ES-2134185-T3 (ES)
Inventor: MCCAPRA FRANK
IPC: C07D249/08

Abstract: In accordance with the present invention, specific binding assays are disclosed which utilize an chemiluminescent compound, i.e., moiety, which has increased stability in aqueous solution. The chemiluminescent moiety is an ester, thioester or amide in which the ester, thioester or amide linkage is between (1) a heterocyclic ring or ring system containing a carbon atom to which the linkage is attached, wherein the heteroatom within the heterocyclic ring or ring system is in an oxidation state which renders such carbon atom susceptible to attack by peroxide or molecular oxygen to form an intermediate which decays to produce chemiluminescence, and (2) an aryl ring or ring system. The aryl ring or ring system contains at least one substituted six-member ring. The substituted six-member ring has two or more substituent groups, where at least two of said two or more substituent groups sterically hinder hydrolysis of said linkage. One or more of the substituent groups which sterically hinder hydrolysis of said linkage may be an electron withdrawing group. The substituted six-member ring may have one or more additional substituent groups in addition to the substituent groups which sterically hinder hydrolysis of the linkage. Such additional substituent groups may also be an electron withdrawing group. The carbon atom in the heterocyclic ring or ring system, to which the linkage is attached, may also have a secondary substituent of the formula RnX-, where X is selected from the group consisting of O, N, S and C, where R is any group, and where n is a number such that X has proper valency. Other chemiluminescent moieties are disclosed which are characterized by a heterocyclic ring or ring system and a secondary substituent of the formula RnX-, with the ester, thioester or amide linkage being between the heterocyclic ring or ring system and a leaving group. The disclosed chemiluminescent moieties can also include substituents at peri positions within the heterocyclic ring or ring system. Also in accordance with the present invention, compositions including and assay kits incorporating such chemiluminescent moieties are disclosed.

Abstract: The AB block copolymers of the prior art generally have a damping curve having a relatively narrow damping range and can only be prepared in a relatively complex manner. In practice, this is regarded as disadvantageous. 
<??>The block copolymers according to the invention comprise
 30 to 90% of a block A and
 70 to 10% of a block B whose mean vinyl and isopropenyl group contents are each at least 30% higher than those of block A.
 These block copolymers have a damping curve of varying width, depending on the point in time of addition of the cocatalyst.

Abstract: A coupling fitting for making joints in reinfocing bars or wires for structural concrete aims to provide a mechanical strength of the coupling virtually equal to the full design strength whilst providing the ability to increase the strength upto and beyond ultimate tensile strength of the rebar by the addition of resin. To that end the coupling comprises a sleeve (1) for fitting in spaced relation around adjacent portions of rebars to be joined and having positively adjustable engagers (3) threaded through the wall of the sleeve, and profiled engagers (17) to engage said portions. The engagers serve for centring the rebars and the profiling serves to provide a key preferably with both the sleeve and the rebar. It is also preferred to have the positively adjustable engagers configured to bite into the rebars. The spaced relation affords provision for introducing settable resin.

Abstract: A water absorbent latex polymer foam produced by the process of combining a foamed latex polymer product with a water absorbent polymer and drying that blend to form a foamable latex polymer containing a water absorbent polymer is disclosed in this invention. The latex foams produced by this process are of great use, for example, within diapers, sanitary napkins, packaging materials and the like. In particular, the use of water absorbent polymers with particle size less than about 30 microns has been shown to produce particularly effective absorbent latex foams. Furthermore, a water absorbent latex polymer foam produced by the process of combining a foamed latex polymer product with both a water absorbent polymer and chitin and drying that blend to form a foamable latex polymer containing both water absorbent polymer and chitin. The latex foams produced by this process are of great use, for example, with wound or surgical dressings.

Abstract: An implant (1) is provided with undercut anchoring surfaces for bone tissue, which extend from the surface (2) into the inside of its body. Arranged under the surface (2), in a specific grid spacing (11), are geometric cavities (5) which, on the one hand, in each case have a through-opening (4) and which, on the other hand, pass under the surface (2) with adjacent cavities (5). A high-pressure liquid jet, which is limited in its penetrating action and to which abrasive particles are admixed, which particles are tolerated by the human body, is used as generatrix and moves relative to the surface (2) in order to generate the geometric cavities (5). With suitable adaptation between cavities (5) and working grid (11), it is possible to produce under the surface (2) arch-like shapes with support columns (6) and through-openings (4), which facilitate the incorporation of bone tissue.

Abstract: The material separation process takes place by machine by comminuting (1) the objects (G) in the mixture so that particles of either non-metallic or metallic material are formed. The particle mixture is subsequently screened (2) of fine parts and then separated (5) electrostatically into a non-metallic (N) and a metallic (M) granulate fraction. The material separation takes place with a high degree of separation, i.e. pure granulate fractions (N) and (M) are produced with only small residual parts of the respective other material. Applications of the process on different kinds of piece goods made of composite material with non-metallic and non-magnetic metal portions are described, such as bottle tops, defective incandescent or fluorescent lamps, processing waste or manufacturing waste of composite materials, for example lined metal foil or aluminium sandwich plates. <IMAGE>

Abstract: There is provided a process for preparing a sub-soluble and splittable, conjugated microfiber with a cross section having matrix orange islands and slightly connected with each other at the tip of the orange island in the matrix center. Conjugated fibers can be made into filaments and staple fibers. Filaments are spinning taken-up and then is carried out texturing by means of a belt nip twister and the resulting texture yarns are sub-dissolved following weaving to split. As to the staple fibers, it is staple fiber processed to obtain staple fibers and followed by processing into non-wovens or spinning to spun yarn and then weaving. Owing to a different splitting method from filament fabrics, staple fibers can be made to fabrics as follows:     1. Suede fabrics;   2. Water resistant and humid permeable, high density fabrics;   3. Peachskin fabrics. o
