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: There is disclosed a stable liquid gel of colorants useful for incorporation in thermoplastic and thermosetting resins. The liquid gel comprises a liquid vehicle which is a plasticizer for the resins and which is gelled by an organophilic, expanding lattice clay which is ion exchanged with alkyl ammonium ions. Preferably the gel is modified by the addition of certain hydroxyalkyl fatty amines or fatty imidazolium quaternaries. The clay is employed at a sufficient concentration to form a stable gel and is milled into the liquid vehicle to form a pre-gel of substantially lesser than the final, desired viscosity.

Abstract: A unitary hub and method of fabricating such a hub for use in conjunction with flywheels for inertial energy storage apparatus, the hub having a double convex domed configuration cut into double spider leg shape upon which a flywheel rim, such as one comprising fiber composite material, may be wound directly. The hub further comprises two cylindrical bars affixed to the center of the outer convex surfaces of the oppositely facing domes to form axles of the hub, and two similar bars which are affixed to the center of the inner concave oppositely facing surfaces of the hub domes to form height limiting devices. Vertical height increasing stress is applied to the hub, resulting in a decrease in the hub diameter. A fiber composite material rim may be wound upon the circumferential perimeter of the hub. This stationary height increased configuration of the hub permits the unitary structure to increase in diameter at high rotational velocities when subjected to severe centrifugal forces.

Abstract: There is disclosed a "cold", i.e., non-radioactive (stable) isotope method for the immunoassay of biological compounds. The method uses selenium as the tracer label in compounds which compete in reaction with a conjugating compound and thus yield a solution for analysis which is a mixture of complexes of the conjugating compound with the selenium labelled and unlabelled compound. The nonradioactive isotope can be analyzed using fluorimetric determinations with proper preparatory treatment or atomic adsorption. Selenium is particularly unique in its adaptability to this assay because of its great compatibility with biochemicals, e.g., it has an atomic size and structure and chemical properties very close to that of sulfur and it readily forms compounds and small adducts with carbon and hydrogen containing compounds. Selenium is also ideally suited for use in this assay because it can be quantitatively detected at extremely low concentrations, e.g., the lower detection limit is presently about 10.sup.-9 to 10.

Abstract: A method of fabrication and the resulting structure for an economical and reliable anchor assembly to retain a conventional bridge plug within the production casing of an oil or gas well. The anchor assembly is efficiently loaded into the well and interfaced with the bridge plug via a packer and tubing, thereby eliminating the necessity of employing an expensive workover rig, which is common to many conventional well plugging techniques. The preferred method includes the step of deforming (i.e. perforating) the production casing for interlocking the anchor assembly therein. By virtue of the instant anchor assembly, a reliable plug may be installed to effectively plug back a depleted zone of an oil or gas well, while withstanding the generally large differential pressures that may be encountered at relatively deep subsurface production zones during a subsequent stimulation of the well.

A hollow coupling sleeve is positioned over the gap, and a dowel or pin is inserted through a hole in the sleeve and into the gap between the bar members. Accordingly, when in the assembled relationship, the sleeve and pin cooperate to inhibit the lateral and angular displacement of the bar members, whereby to prevent removal of the security bar from the guarded area after installation between the structural supports thereof.

Abstract: There is disclosed a method for the elimination of the chief impurities in aluminum dross tailings. The method can be used as a pretreatment in the manufacture of aluminum sulfate from aluminum dross tailings in a continuous flow reaction zone in which the dross tailings prior to reaction with sulfuric acid are pretreated to reduce the more objectionable contaminants contained therein to acceptable levels. The most objectionable contaminant in the dross tailings is aluminum metal which, in the invention, is oxidized with water or steam at elevated temperatures. The dross tailings, which are chiefly particles of aluminum oxide, are suspended in an aqueous slurry and the slurry is heated to a temperature from 185.degree.-225.degree. F. and maintained under liquification pressures and sufficient agitation to insure particle-to-particle attrition that removes an aluminum hydroxide coating which would otherwise inhibit the reaction.
