An enclosed container is provided comprising at least one first aperture, the first aperture(s) being provided with a first closure means and through which the contents of said container may be dispensed upon at least partial removal or opening of said first closure means, and at least one second aperture which is independent of at least one of said first aperture(s), the or each second aperture being provided with a second closure means and through which second aperture or apertures the contain...

The invention relates to Tetranectin, a new protein isolated from blood. Its structure comprises four polypeptide chains having the formula shown in the attached drawing. Tetranectin plays a role in the hemostatic system and, therefore, may be used as an agent for regulation of hemostasis. Further, the invention relates to a process for preparing Tetranectin in which Tetranectin is isolated, e.g. from blood or blood fractions, cells or genetically engineered organisms. Finally the invention rela...

A valve comprising a rigid tube in which a flexible tube is situated with the two ends of the flexible tube being connected in sealed manner to the ends of the rigid tube, a control orifice being provided through the wall of the rigid tube in the vicinity of its middle region, and a core also being disposed inside the flexible tube, the core being smaller in cross-section than the inside section of the tube when in the rest state, wherein the core has a calibrated internal passage. The valve is ...

This invention relates to a fiber comprising a major amount of a continuous phase comprising one or more melt processible polyesters of fiber forming molecular weight, and a minor amount of one or more polyolefins non-uniformly dispersed in said continuous phase such that the concentration of polyolefins at or near the surface of said fiber is greater than the concentration of polyesters at or near the surface of said fiber, and a process for preparing said fiber.

A folding belt system having the head and tail pulleys twice the width of the support idler rolls and having a transition length of about 7 to 15 times the width of the belt between the fold or hinge lines, where transition width support rolls are located. The folding conveyor belt is composed of a central belt section which has specially constructed flexible areas at each edge extending longitudinally the length of the belt to which are attached cover flaps. The cover flaps completely enclose t...

The present invention provides pavement and a paving material in which a large quantity of aggregates are bound with one another by a hot melt of thermoplastic resin powder, and also provides producing methods of such pavement and such paving material. The thermoplastic resin powder is neither limited in pot life, nor influenced by working conditions and weather conditions at the time when pavement is laid at a job site. Accordingly, uniform strength can be given to the resulting pavement or pav...

The invention relates to a process for the preparation of suspensions of at least one polymer, said process comprising as a first step the preparation of a first suspension of at least one polymer in an organic liquid by chilling a solution of said polymer. In accordance with the invention, there is added to the first polymer suspension in a second step a powder of at least one polymer, which may be the same as or different from the first. Use of said process in the production of two-layer compo...

The invention relates to a matrix suitable for use in the replication of a plastic element having a positive microstructure, comprising a first wear-resistant layer that is supported by a carrier element, wherein the matrix comprises a heating means for supplying electrical heat energy through the wear-resistant layer or carrier element. The invention further relates to a plastic element producing machine and a method for the manufacture of a plastic element having a surface with a positive micr...

The present invention relates to compatibilizers useful to laminate a layer of a vinyl aromatic polymer such as polystyrene and a polyester such as PET. The compatibilizer comprises a mixture comprising 5-95 weight % of a polyester, 95-5 weight % of an impact modified polymer of a vinyl aromatic monomer such as high impact polystyrene (HIPS) and from 5 to 20 weight % of a hydrogenated block polymer of a vinyl aromatic monomer and a conjugated diolefin sometimes called SEBS.
