  • Patent number: 5276816
    Abstract: A system and method for interpreting messages sent from an I/O device to an application object in an object-oriented environment, such that the messages interpretation of these messages will be consistent regardless of the I/O device used to generate them. Dynamic binding is used to interpret any object-object interactions that may occur. In general, the message interpretation abilities of the present invention allows additional I/O devices to be used with the object-oriented environment without having to update all the application objects in the environment.

  • Patent number: 5273667
    Abstract: A method for treating the phosphate sludge waste from phosphate conversion baths used in the metal forming and metal working industry is described whereby the phosphate sludge is completely converted into a lubricant additive which can be used in lubricant formulations for the metal forming and metal working industry as well as general purpose lubricants. By operation of this process, waste treatment and waste disposal problems associated with the phosphate sludge are essentially eliminated. Various dry-soap lubricant formulations, warm forming lubricant formulations, non-reactive lubricant formulations, and metal precoat formulations containing the recovered or recycled phosphate sludge additive are described. The lime normally contained in many of these lubricant formulations can be significantly reduced or essentially eliminated by using the recovered phosphate sludge additive of this invention, thereby resulting in improved lubricant formulations.

  • Patent number: 5274077
    Abstract: A novel retinoic acid receptor is disclosed. The novel receptor is encoded for by CDNA carried on plasmid phRAR1, which has been deposited with the American Type Culture Collection for patent purposes. Chimeric receptor proteins are also disclosed. The chimera are constructed by exchanging functional domains between the glucocorticoid, the mineralocorticoid, the estrogen-related, the thyroid and the retinoic acid receptors. In addition, a novel method for identifying functional ligands for receptor proteins is disclosed. The method, which takes advantage of the modular structure of the hormone receptors and the idea that the functional domains may be interchangeable, replaces the DNA-binding domain of a putative novel receptor with the DNA-binding domain of a known receptor such as the glucocorticoid receptor. The resulting chimeric construction, when expressed in cells, produces a hybrid receptor whose activation of a ligand--(e.g.

  • Patent number: 5274493
    Abstract: An electrochromic element useful in an electrochromic glass or mirror device and a process for making such element. The element is a five-layered structure including an electrolyte ion conducting layer interposed between first and second inorganic electrochromic layers which are interposed between a pair of conductive electrodes. The second inorganic electrochromic layer is amorphous. The first and second inorganic electrochromic layers are different and are capable of exhibiting color-forming properties complementary to one another upon the incorporation of at least one H, Li, Na, K, Ag, Cu or Tl ion. The electrolyte ion conducting layer may be a copolymer of ethylene oxide, butylene oxide or methyl glycidyl ether, and optionally a small amount of allyl glycidyl ether, along with an ionizable salt, or may be a polyurethane gel formed by reacting the copolymer with triisocyanate, along with an ionizable salt.

  • Patent number: 5273248
    Abstract: A pair of boards are hinged together to form a double sided easel. The boards can be moved to a coplanar position to form a child's bed. The easel has a pair of easel trays that become legs for the bed. Side boards on the outer sides of the boards become side rails on the bed. End boards on the boards support the easel on a supporting surface and become a head board and a foot board for the bed.

  • Patent number: 5273945
    Abstract: A catalyst is provided which contains 1 to 99 wt. % of a zeolite related to faujasite and having a hexagonally symmetrical structure and an Si:Al ratio between 3 and 30. The compensation cations of this zeolite consist partly or wholly of cations of one or more elements chosen from H, B, Al, Ga, In, rare earth metals and transition metals. The catalyst can also contain up to 15%, referred to the total weight of the binder and zeolite, of a catalytically active metal of the noble, non-noble transition or other type which is not already present in the compensation cations of the zeolite. The catalyst can be used in acid catalysis reactions carried out on hydrocarbon feedstock, in particular in fluidized bed catalytic cracking.

  • Patent number: 5272066
    Abstract: A method for modifying eukaryotic and prokaryotic proteins to extend their in vivo circulatory lifetimes. In the preferred embodiment, enzymatic and/or chemical treatments are used to produce a modified protein carrying one or more covalently attached trisaccharide, sialic acid.fwdarw.galactose.fwdarw.N-acetylglucosamine.fwdarw.(SA.fwdarw.Gal.fwd arw.GlcNAc.fwdarw.), or tetrasaccharide (SA.fwdarw.Gal.fwdarw.GlcNAc.fwdarw.GlcNAc.fwdarw.) moieties. The method can be applied to any natural or recombinant protein possessing asparagine-linked oligosaccharides or to any non-glycosylated protein that can be chemically or enzymatically derivatized with the appropriate carbohydrate units. Following injection into an animal, the modified glycoproteins are protected from premature clearance by cells of the liver and reticulo-endothelial system which recognize and rapidly internalize circulating glycoproteins with carbohydrate chains containing terminal Gal, GlcNAc, fucose or mannose residues.

  • Patent number: 5259061
    Abstract: The manufacture of an optical waveguide device utilizing a fast, accurate method for tuning of the output phase angle of such devices to a desired operating point. Tuning is accomplished by adjusting the accumulated phase along a waveguide arm of the device by removing optical waveguide material using laser ablation. Due to the change in waveguide geometry in the ablated region, the optical phase velocity is changed and thus the optical path length is affected in that section of waveguide, thereby resulting in a change in output phase angle.

  • Patent number: 5258855
    Abstract: An information processing methodology gives rise to an application program interface which includes an automated digitizing unit, such as a scanner, which inputs information from a diversity of hard copy documents and stores information from the hard copy documents into a memory as stored document information. Portions of the stored document information are selected in accordance with content instructions which designate portions of the stored document information required by a particular application program. The selected stored document information is then placed into the transmission format required by a particular application program in accordance with transmission format instructions. After the information has been transmission formatted, the information is transmitted to the application program. In one operational mode, the interface interactively prompts the user to identify, on a display, portions of the hard copy documents containing information used in application programs or for storage.

  • Patent number: 5258198
    Abstract: The previously stated specification is an indepth description of my invention. This product offers an appeal by its natural color and ingredients. There are three distinct flavor sensations the consumer will experience, sweet, sour, and the natural spicy flavor of a garden grown pepper. The product consists of Hungarian and Romanian Wax Peppers, cored and de-seeded and stuffed with a sauerkraut mixture and immersed in a brine with dill weed immediately reacting with the chemistry of the vegetables themselves; thus, allowing an instant flavor impregnation so that no formal canning procedure (unlike that contained in the "Pickled Green Pepper", by Hugo Ziemann) is required to achieve the taste. The product is currently canned in a one quart glass jar, but is not necessarily restricted to that particular size of container.
