Abstract: Apparatus to provide improved archery accuracy, by correcting bow handle twist problems, includes: a bar, attached to the bow handle parallel to the position of the arrow; an elastic cord, band, or tube, attached at one end to a front portion of the bar and at the other end to the bow string at a point which aligns the elastic cord with the bar when the bow is at full draw. Slight twisting of the bow handle causes a lateral movement of the rear portion of the bar relative to the elastic cord. Observation of this movement by the archer permits him to change his grip of the bow handle to eliminate the twist and thus improve accuracy. Observation of such movement of the rear portion of the bar is enhanced by placing a small plate at the rear end of the bar together with a pointer on a pivot pin. Other improvements include use of electrical contacts and lights to indicate the presence or absence of twist.

Abstract: An inflatable hat, preferably constructed of a metallized gas-impermeable polymeric sheet, may be provided in any of a number of novelty shapes, forms, colors, designs, and the like. Inexpensive construction affords adaptability to toys, advertising, sports promotions, and various theme objectives.

Abstract: A towel serves additionally as a headband and head covering when held in place by extended strips which fasten together at the back of the head. The towel is pulled back over the head and held in place with fasteners placed on both the towel and the extended strips. It is pulled forward over the head, for removing perspiration and grime from the face and neck area, and conveniently returned over the head during activity. It is also useful to protect from heat or sun while doing heavy physical work, sports activities, lying on the beach, and the like.Alternatively, the headband closure member comprises an elastic-containing band to effect a firm positioning about one's head.

Abstract: Industrial, municipal, sanitary, marine, and infectious waste materials are thermally and chemically converted principally to steam, fuels and environmentally acceptable solids by dehydration, pyrolysis of the solid residue therefrom, and finally gasification of the pyrolysis char residue. In contrast to incineration processes, the products have significant market value and present no atmospheric pollution problems. Temperatures employed range up to about 3000.degree. F.

Abstract: An improved lubricant additive, for imparting improved friction reduction and anti-wear properties to crankcase oils comprises a modified mixed amide, derived from reaction of a substantially saturated fatty acid triglyceride with a deficiency of dialkanolamine, either alone or in combination with a sulfurized substantially unsaturated fatty acid triglyceride which may be transesterified for improved solubility.

Abstract: This invention relates to means for retaining enough of the heat of a hot cooked meal while the meat is being consumed, to enhance the pleasure of eating the entire meal.

Abstract: Racemic hernandulcin, a sesquiterpene, possesses a sweetness intensity about three orders of magnitude greater than that of sucrose. It is non-mutagenic and non-toxic under conventional assay procedures. In addition to attractive utility in foods, beverages and pharmaceutical compositions, it affords a low-cariogenic, essentially non-nutritive sweetening agent for inclusion in oral hygiene products.

Abstract: An improved portable apparatus is provided for the flow-through measurement of analytical parameters of liquids, particularly ground water. A concave end design, employing transparent materials, together with selected transparent pipe sections, affords an adjustable cell volume to minimize turbulence at the point of analysis, while also monitoring electrode fouling.

Abstract: Bacteriophages are employed as agents for recognition and identification of molecules and cellular materials, using their ability to recognize their bacterial host, by coating them with antibodies or by selecting them to perform in a manner analogous to antibodies. Visibility for identification is effected by incorporating a fluorescent agent, a radioisotope, a metal, an enzyme, or other staining material. The bacteriophage are prepared so as to bind to the molecular or cellular material through either the tail or head segment of the bacteriophage.

Abstract: Fine particles of solid fossil fuels are pyrolyzed by passage in a thin layer through a heating zone at successively higher temperatures in a non-oxidizing atmosphere while rapidly separating and removing volatile pyrolysis products. The resulting char may be first treated with mineral acid or employed directly in the hydroprocessing of additional solid fossil fuel to liquid fuels. Alternatively, the acid-washed char may be hydrotreated to afford an improved char product having a low sulfur and mineral content.

Abstract: Laser systems, exhibiting energy conversion efficiencies greater than 20%, employ divalent metal halides, dissociated either electrically or optically, and pumped optically, usually by means of an arc lamp or an incoherent flashlamp. Either pulsed and continuous-wave lasing can be effected in or near the visible region.

Abstract: Improved combustion efficiency is achieved by separately preparing a water-in-oil emulsion, containing up to about 90 volume % water, and blending the emulsion into an oil fuel prior to combustion. The blended oil fuel contains from 1 to about 10 vol. % water in the form of tiny droplets having a diameter within the range from about 1 to about 10 microns. The process of this invention may be applied to heating systems, steam boilers, gas turbines, rotary kilns, and internal combustion engines, including diesel engines.

Abstract: Food supplement compositions for the enhanced absorption of nutrient mineral components additionally include a complex carbohydrate fraction, having an average molecular weight in the range from about 750 to about 3500, and a suitable carrier agent. The compositions are particularly includable in the diets of subjects who have a shortened interstinal length and need additional absorption of calcium and other mineral elements.

Abstract: Improved low-foaming, water-soluble, rust-preventative compositions comprise a partial amide of an alkanolamine and unsaturated dicarboxylic acid, together with an aliphatic dicarboxylic acid salt of an alkanolamine.

Abstract: A phospholipid mixture, rich in N-acylphosphatidylserine (NAPS), is produced by growth of certain bacterial cultures in media containing effective amounts of tris (hydroxymethyl) aminomethane. NAPS may be isolated in high purity by chromatographic techniques.

Abstract: Unusual power enhancement and a plurality of output wavelengths in the visible or near-infrared regions are obtained simultaneously from a laser in which the vapors of two or more Group II-B metal halides are dissociatively excited either in an electrical discharge or by photodissociation by an external laser. By using halides involving only one metal and/or halogen isotope, the power output is greater than that obtainable with natural abundance salts. The laser output is also more confined spectrally. Over 50% of the power is contained in one or two spectrally narrow lines that are associated with a particular metal halide molecule.

Abstract: The efficiency of pulsed laser systems is enhanced substantially by injecting a minor amount of radiation energy into the system .DELTA.t seconds prior to the emergence of the laser pulse. The degree of power enhancement is a function of both radiation wavelength and time delay.

Abstract: There are provided a process for preparing a suspension of elemental sulfur in a fluid, a process for preparing a sulfurized cutting fluid, and products that are obtained from the processes. A high-shearing mechanical device is employed in either process to transform an unfinished suspension of sulfur in a fluid into a stable suspension of finely-divided sulfur.
