A linear cable laying engine has a pair of endless belts (12,14) having a substantial length (16,18) in respective face to face opposition, and means for applying force to the belts to cause them to grip a cable (42) between the opposed faces.
摘要:
A heat extracting substrate is moved along a melt front formed at the edge of the surface of a molten material so that a layer of molten material is deposited on the substrate, cooled and removed from the substrate to form ribbon, filaments, fiber of film directly from the molten material. The edge may be formed by providing an upper edge upon a portion of the wall of a receptacle lower than the top of the receptacle. The molten material may be overflowed over this relatively horizontal edge and against the moving substrate surface.
摘要:
The present invention relates to a method of manufacturing widgets from components and/or particulate; and to a can for containing such components and/or particulate during the consolidation into widgets. The method of the present invention can be used to form widgets from metals, ceramics, plastics, polymers, and/or combinations thereof. The materials used to form the widgets can be in the form of particulate, pellets, shard, and/or ribbon. The method of the present invention can also be used to join widgets and/or to heal ingot cracks.
摘要:
Modified Wee1 peptides, polynucleotides encoding those peptides, and methods for purifying the peptides and crystallizing them as peptide: inhibitor complexes have been discovered. The three-dimensional structure of Wee1, including the ATP substrate binding site, and uses of this information in the design and screening of compounds that may associate with Wee1, or peptides structurally related thereto, have also been discovered.
摘要:
A method of preparing a porous article is provided. The method includes: contacting a porous substrate with a first reactant that enters pores of the substrate; and contacting the porous substrate bearing the first reactant with a second reactant that is capable of reacting with the first reactant in an interfacial polymerization reaction; the amounts of first and second reactant being selected such that there occurs no, or substantially no, closing of pores of the substrate by the formed polymer. The invention also provides a porous article bearing a compound which is photochemically reactive and capable of undergoing a substantially non-reversible chemical transformation upon exposure to ultra-violet, visible or near infra-red irradiation. The photochemically reactive compound can be derivatized by irradiation and further reaction to provide a wide variety of useful membranes, for example, for microfiltration or for biochemical reactions and separations.
摘要:
The invention is a slicing orifice for use with a foodstuff slicing machine wherein the foodstuffs have been formed into loaves and the slicing machine includes a tray with a bed, a feed guide, a loaf indexing drive, a cutting head, an upper and lower clamping portion, a plurality of semicircular orifices in the clamping portions and being laterally offset from one another, wherein each orifice has a plurality of longitudinal gripping channels to effectively retain the foodstuffs during cutting.
摘要:
The present invention is for a flat platelet powder for deposition onto a substrate. The powder is formed by fracture of brittle sheet or ribbon. The resulting powder has a faceted outline formed by fracture. The powder of the present invention produces a dense deposit.
摘要:

摘要:
A method for recovering a usable alloy consisting of 2.5 - 3.5% aluminum, 1.7 - 2.50% tin and balance titanium from titanium scrap is disclosed. The method comprises cleaning the scrap, charging the cleaned scrap into an electron beam furnace and refining the charge under a hard vacuum so as to attain a predetermined composition.
