Abstract: Tris(isonitrile)copper(I) complex salts with anions selected from BF.sub.4, PF.sub.6, ClO.sub.4, I, Br, Cl and CF.sub.3 COO are useful in preparing radionuclide complexes rapidly at room temperature. Preferred isonitrile ligands are ether isonitriles. The tris(isonitrile)copper(I) adducts enable technetium complexes, such as those of Tc99m, to be prepared easily just prior to their use as imaging agents.

Abstract: A hierarchial library of spectra representing the point-by-point characteristics of known samples is created. Vectors representing each spectrum are classified according to their similarlity and dissimilarity. Vectors representing unknown samples are compared to known groups of vectors according to similarity until a near match is found.

Abstract: Stain-resistant compositions comprising sulfonated phenol-formaldehyde condensation products and polymers of ethylenically unsaturated monomers, polyamide textile substrates treated with the same, and processes for their preparation. The stain-resistant compositions and substrates possess improved stain resistance but do not suffer from yellowing to the extent that previously known materials do.

Abstract: An expert system wherein the rules are of three classes: (1) retrieval rules, which each associate one of several attributes to an object in accordance with the values of inputs; (2) analysis rules, which selectively associate an attribute with an object, and which are somewhat analogous to the natural-language inference rules which would be used in communications between domain experts; and (3) action rules, which selectively carry out the output and control actuation options, based on the attributes associated with objects by the other rules.Preferably only the action rules can enable execution of an external command procedure. Preferably each of each of the action rules requires no logical operations other than a test for association between an attribute and an object. Preferably none of the action rules can associate an attribute with an object. Preferably only the retrieval rules include numeric operations.

Abstract: Compounds having the formula ##STR1## and pharmaceutically acceptable salts thereof, wherein R.sub.4 is aryl are disclosed. These novel compounds are useful, for example, as cardiovascular agents.

Abstract: A process for dyeing crystalline poly(meta-phenylene isophthalamide) fibers with a water-insoluble dye padded onto such fibers by heating with steam at critical temperatures first to activate the dye and thereafter to diffuse it into the fibers.

Abstract: High modulus, high tenacity fibers of poly-p-phenylene terephthalamide (PPD-T) are manufactured comprising a fiber heat treating process for increasing the inherent viscosity and the crystallinity index of the PPD-T. Never-dried fibers swollen with water of controlled acidity are heated beyond dryness in an atmoshphere having a flow of greater than Reynolds Number 10,000 throughout the duration of the heating.

Abstract: X-ray phosphor consisting essentially ofGd.sub.1-X BO.sub.3 :Ce.sub.Xwherein X is 0.001 to 0.09 and process of preparation wherein reactant sources of gadolinium, boron and cerium, e.g., oxides, and flux, e.g., mixture of alkali metal halide and tetraborate, mixture of alkali metal sulfates, are mixed and fired at a temperature in excess of that required to melt the flux, leaching out the flux with water and drying to obtain substantially spherical particles, 0.5 to 20 .mu.m in average diameter. The X-ray phosphor is useful in an X-ray screen which is used in combination with a silver halide, e.g., silver bromide emulsion.

Abstract: A deck for a mobile home is supported on the undercarriage of the mobile home to roll in and out between a retracted position in which the deck is wholly located beneath the mobile home and an extended position in which the deck extends laterally from the mobile home. Channels secured to the frame of the mobile home receive wheels on opposite sides of the deck. The deck has fold up rollers on its leading end which roll along the ground and elevate the deck above the ground. Each roller is carried on a leg which is adjustable in its length.

Abstract: Methods of making assemblies and assemblies for interconnecting optical fibers and use in integrated optical systems. The optical fiber connector assemblies include a pedestal having a step supporting an optical waveguide device having a buried waveguide. End portions of the step support means for receiving cores and cladding of optical fibers with the optical axes of the cores in alignment with the optical axis or axes of the waveguide.

Abstract: A shift device for a prosthetic limb comprises: first and second plates having adjoining flat faces in sliding contact. Spaced parallel ribs on an outer face of each plate define a slideway. Guides in the slideways of the first and second plates enable the plates to move generally at right angles to one another. The guides include first and second guide bars slideably received in the respective slideways. One or more longitudinal slots in each slideway permit limited relative translational movement of the plates. Clamping screws pass through each slot of each of the first and second plates into the guide bar in the slideway of the other plate. The clamping screws are releasable to allow relative movement of the plates and on re-tightening immobilize the plates.
