Abstract: Highly immunoreactive regions of gp41 of HIV-1, gp32 of HIV-2 and p24 of HIV-1 were identified using synthetic peptides. Superior immunoassay performance is obtained with these peptides linked to carrier proteins as compared to use of the free peptides. Additional natural and unnatural variants of these reactive regions to define a set of peptides that, as cysteine-linked peptide-protein conjugates, provide optimal immunoassay performance including high immunoreactivity with HIV antibody positive samples, low reactivity with negative samples, high discrimination between positives and negatives, and high specificity. These peptide conjugates further permit simultaneous detection of HIV-1 and HIV-2 antibodies, and make possible rapid and simple test formats that require no instrumentation for detection of these antibodies.

Abstract: A dual vibrating beam force transducer having an electrostatic drive system. The transducer comprises a body (12) having first and second generally parallel beams (20, 22), coupled together at their ends. First and second electrodes (14, 16) are positioned adjacent to but not in contact with the respective beams. A drive circuit (18) causes an oscillating voltage to be applied to the electrodes. The beams are thus subjected to electrostatic forces that cause the beams to oscillate in a vibration plane containing both beams. The mechanical resonance of the beams controls the oscillation frequency, such that the frequency is a function of a force exerted along the beams. An embodiment is also described in which the drive means is coupled directly to one of the beams.

Abstract: Solid, water-insoluble lipospheres formed of a solid hydrophobic core having a layer of a phospholipid embedded on the surface of the core, containing biologically active agent in the core, in the phospholipid, adhered to the phospholipid, or a combination thereof, are disclosed for use in providing extended release of active agent, including drugs such as vaccines and anesthetics, insect control agents such as insecticides and repellents, and agricultural compounds such as fertilizers, fungicides, pesticides, and herbicides. Lipospheres can be prepared by a melt technique or a solvent technique, summarized as: (1) forming a liquid solution or suspension of the agent by either melting the agent, or dissolving or dispersing the agent in a liquid vehicle, to form a mixture of liquid agent that solidifies at room temperature or greater; (2) adding phospholipid and an aqueous solution to the liquid agent to form a suspension; (3) mixing the suspension at a temperature above the melting temperature until a homogeneous fine dispersion is obtained; and then (4) rapidly cooling the dispersion to below the melting temperature of the liquid mixture containing the agent. Agent can also be added to the phospholipid or mixed with the resulting lipospheres. The agent containing lipospheres have several advantages over other delivery systems, including emulsions, vesicles and liposomes, including stability, low cost of reagents, ease of manufacture, high dispersibility in an aqueous medium, a release rate for the entrapped substance that is controlled by the phospholipid coating and the carrier. Examples demonstrate the effective administration of anesthetics, antigens, and insect repellent (DEET).

Abstract: A food-safe composition for the pretreatment of a surface, preferably an oven or a broiler, which may be subjected to heat is liable to soiling by organic food deposits, especially baked-on food deposits. A food-safe, inorganic thickening agent which is substantially insoluble in an alkaline aqueous composition and which is present in an amount sufficient so that, during application to the surface, the composition is capable of forming a continuous coating adhered to all desired portions of the surface, is combined with (1) an alkaline, food-safe, water-soluble inorganic salt in an amount sufficient so that the composition is readily removable with water or an aqueous solution after the composition has been dried and soiled and (2) a high-boiling, organic component selected from the group consisting of (a) ethers having more than seven carbon atoms and (b) aliphatic esters having carboxylic acid-derived portions of more than seven carbon atoms, wherein said high-boiling, organic component is present in an amount sufficient so that the continuous coating remains continuous as the coating dries. The composition forms a film after drying, preferably by heating, which remains continuous over all portions of the surface, including areas which may already be soiled with food deposits. After the film accumulates additional food soils, the soiled film can be readily removed by contact with water or an aqueous solution.

Abstract: A security switching device (1) is used for monitoring two sensors (2,2') which check the same function in a system. The two sensors (2,2') are connected to associated inputs (4,4') of the security switching device (1). The security switching device (1) contains two timing circuits (9,9'), each of which is allocated to one input (4,4'). The timing circuits (9,9') only supply an output signal when the signals at the inputs (4,4') of the security switching device (1) simultaneously rise to the operating value within the time windows implemented. If this is the case, a feedback circuit (11) becomes effective which initially suppresses the effect of the time windows until the signal returns from the value in the operating state to the rest state at one of the inputs (4,4'). <IMAGE>

Abstract: A method of treating coal. The method comprises passing the coal through a retort having a shell temperature of about 500-1000 DEG F and shock heating the coal to a maximum surface temperature of about 500-1000 DEG F without allowing the coal to become exothermic. The coal is prevented from going exothermic by a combination of factors, including the evaporation of moisture from the shock heated coal, the tendency of coal to absorb heat and maintain a temperature of about 390-570 DEG F until the coal undergoes molecular transformation of comp lex hydrocarbons contained in the coal to simpler forms, and the effects of a cooling blanket gas passed through the shock heated coal. The blanket gas preferably comprises an oxygen lean blanket gas stream containing about 2-8% oxygen by volume. The treated coal exhibits extremely low moisture content and increased BTU value and other improved combustion characteristics.
