Abstract: A method of measuring relatively small amounts of hydrocarbon oil contained in water, or other immiscible liquids including mixing a solvent and a conductivity additive with the oil and water or immiscible liquid, hereinafter termed "water" as it will be the most prevalent use, to form a mixture. The solvent is water rejecting and extracts the oil from the water. A method of producing a chemo-conductivity additive to render the electrically non-conductive oil of the mixture electrically conductive without rendering the solvent conductive or adding to any existing water conductivity. The amount of oil is electronically ascertained by measuring the conductivity of an electrical current passed through the mixture after the oil has been rendered conductive.A novel apparatus is provided to perform the process. The apparatus comprises all the elements for carrying out the process including a separating funnel, measuring beaker, electrode assembly, electronics assembly and both analog and digital displays.

Abstract: A combined sighting target and bracket adapted for receiving a reflector housing for use with electronic distance measuring instruments in surveying and other civil engineering applications. The unique structure permits adjustment of three parameters that render the present invention generally compatible for use in conjunction with virtually any kind of electronic distance measuring instrument. One such adjustment, namely, vertical displacement between a reflector housing and the sighting target, permits duplication of any offset distance that exists between a telescope and ranging optics of the remotely located measuring instrument. The other adjustment features include elevation and azimuth angle variations that permit orientation of the reflecting device to be virtually normal with respect to the incoming and reflected laser, infrared, or other such energy commonly used by such electronic distance measuring instruments.

Abstract: An improved solid cleaning and polishing compound consisting of a mixture of non-abrasive powders and oils. A powder-like mixture of diatomaceous silica and jeweler's rouge is combined with a mixture of mineral and linseed oils. The resultant combination of mixtures is sifted (to remove undesirably sized particles) and then stored in an air-tight container for a period of time sufficient to achieve suitable curing or aging.

Abstract: There is disclosed an improvement in a selective adsorption process wherein a gaseous mixture of gas components is separated by contact with a compact, moving bed of particulate adsorbent having a selected adsorbency for one of the gas components which is thermally desorbed therefrom. The process of the invention comprises contacting the hot, thermally desorbed adsorbent with recycle lean gas in a sufficient amount and through a sufficient depth of stripping zone to effect substantially complete desorption of the rich gas component therefrom prior to introduction of the adsorbent into the fractionating zone of the process. The process is particularly useful for the separation of gaseous components which are extremely difficult to separate by cryogenic techniques.

Abstract: A clip for releasably securing at least one package of the type adapted for hanging on a display bracket, the clip comprising a bayonet portion for guiding the package onto a bracket, and a securing loop that is opened and closed by means of a spring-type locking mechanism, the loop and locking mechanism being integrally formed with the bayonet portion. In one embodiment, the locking mechanism comprises a V-shaped member having its apex extending below and in close proximity to the bayonet portion when the loop is closed.

Abstract: A temperature measuring apparatus or device for measuring the temperature of an object or a series of closely adjacent objects through the measurement of relative infrared radiation is normally referred to as an infrared thermometer. Known infrared thermometers can be modified so as to be useful in making stress-degree measurements as are needed in determining when plants or crops should be watered or irrigated by including within such devices a temperature detector capable of providing an electrical signal. Such modified thermometers include a circuit which relates the signal produced by the temperature detector to the signal produced by the infrared radiation detector used in such a device so as to display the difference between the temperature detected by the infrared detector used and the temperature detected by the temperature detector.

Abstract: An improved bidirectional plug valve with increased C.sub.v or decreased insertion pressure loss is provided. The improvements reside in a unique combination of surprising structural parameters including an increase in the diffuser-to-dump transition radii, a high degree of dimension match for diffuser and plug chamber, an unconventionally large diffuser angle, and most surprisingly, a reduction in plug port size with a substantial corresponding reduction in plug size and dump area. The indicated structural features of the invention, combine synergistically to provide an unexpected C.sub.v improvement of approximately 50% and a substantial cost reduction for the valve operating mechanism.

Abstract: There is disclosed a calculating and recording device of the slide rule type for determining and retaining play statistics of a football game. The device has a body bearing at least one, and preferably two, coextensive grooves, each of which can receive a slide which is calibrated in indicia of arithmetic progression coextensive with the length of the slide. The rule includes removable marker means each bearing an indicium of a single class of a plurality of distinct classes of indicia representing plays or types of plays of a football game and the body of the rule has at least three parallel rows of receiver means in arithmetic spacing equal to the spacing of the indicia of the slide which receive the removable marker means to record passing, rushing and first down statistical information.

Abstract: A unitary, wide rim of fiber composite material for use in conjunction with flywheels for inertial energy storage apparatus, the rim being fabricated to minimize radial stresses and equalize hoop stresses ordinarily produced at high speed rotation of the flywheel. Novel fabrication techniques include varying the density of the rim as a function of radius by means of ballasting; varying the ratio of the fiber and epoxy mixture as a function of radius; varying the winding tension of the fiber as a function of radius; using a combination of layers of fibers having different modulus of elasticity; and varying the winding geometry of the fiber from non-circular to circular as a function of radius. By utilizing two or more of the aforesaid novel fabrication techniques, a preferred embodiment of a unitary, thick flywheel rim achieves radial stress reduction to trivial levels and hoop stress equalization sufficient to permit extremely efficient energy storage as a function of flywheel weight.
