Abstract: A coating composition which is capable of being used effectively in a wide variety of applications where heretofore known coating compositions could not be used, or where their use was accompanied by various disadvantages is disclosed. The curing temperature at which coatings (for example, corrosion resistant coatings) are formed from an aqueous coating composition containing dissolved phosphate, dissolved dichromate, dissolved aluminum, and solid particulate material is lowered by adding diethanolamine to the composition. The coating composition of the present invention can be used to effectively coat substrates which heretofore could not be coated or could not be coated satisfactorily as a result of the substrate being destroyed or degraded by the relatively high temperatures that were required to satisfactorily cure heretofore known coating compositions.

Abstract: An active nutation control system for a space vehicle spinning about a geometric axis has thrusters for creating an external torque about an axis transverse to the first. The amplitude of the nutation and its phase in relation with the spinning movement are detected. A control arrangement receives signals from the nutation detectors, computes the changes in the angular direction of the angular momentum of the vehicle caused by thruster activation and energizes the thrusters when contemporaneously the amplitude of the nutation movement is greater than a predetermined threshold, the phase corresponds to maximum efficiency of said thrusters in reducing nutation momentum of the vehicle or at least does not increase it.

Abstract: A cleaning device for cleaning a conveyor belt comprises a cleaning member mounted on a lever which can move angularly about a pivot axis extending transverse to the run of the belt, the lever also carrying a pressure member arranged to contact the face of the belt opposite to the face to be cleaned, the cleaning member being urged into contact with the surface of the belt by the reaction of the pressure member to movement of the belt causing angular movement of the lever about its pivot axis. The pressure member and cleaning member may be resiliently urged towards one another in the direction of the axis of the lever to enable wear of the cleaning member to be compensated automatically while reducing the angle through which the lever pivots during the useful life of the cleaning member.

Abstract: Fittings and methods for manufacturing fittings for piping are disclosed. The fittings are assembled from three identical molded pieces joined along longitudinal edges.

Abstract: Equipment is disclosed for gas blast attenuation of attenuable materials by the toration type of technique according to which a gaseous jet is directed transversely into a gaseous blast of larger cross section, thereby developing a zone of interaction of the jet and the blast into which a stream of the attenuable material is delivered. Each fiberizing center incorporates a plurality of components including means for generating the jet, means for generating the blast, and means for supplying the stream of attenuable material. In addition, the fiberizing center frequently also incorporates an additional structural element or means positioned along the path of the jet and influencing the jet flow.

Abstract: For locally stripping an electric wire, the wire is maintained in a guide, the insulating material is cut with rotary knives over a fraction only of its thickness and the residual insulation material is broken by pulling after the knives have been stopped. An apparatus for carrying out the process has a stripping head supporting a wire-guide, provided with a drive motor for rotation about the axis of the guide and carrying knives radially movable between an inner and an outer position. An electromagnetically controlled wire-clamping system is used for axially moving the wire.

Abstract: An analysis system with which a random number of small to very small liquid specimens can be simultaneously examined side by side without hollow reaction vessels. The specimens do not mix together and do not dry out.To this end, the plates are provided with a water-repelling coating leaving free a number of circular surfaces. The individual specimens are placed between the coinciding circular surfaces of two superimposed plates. A frame ensures that there can be no reciprocal lateral sliding of the plates and that the latter do not move too close to one another. For mixing of the individual specimens, the plates can be rhythmically moved towards and away from one another within given intervals, e.g. by means of a spring-magnet system.The analysis system can be used in many immunological examinations, particularly blood group determinations, radioimmunoassays, enzyme-immunoassays, immunofluoroescent assays and in non-immunological, general chemical, biochemical and clinical chemical examinations.

Abstract: A process and apparatus for forming fibers from attenuable materials, such as molten glass, by attenuating streams of glass from the bottom of a bushing wherein the bottom has downwardly presented wall portions at upper and lower levels. According to the disclosure the upper and lower wall portions are formed into series of elongated channels, separated by grooves in the underside of the bushing. Filamentary material is manufactured by drawing at least one filament from each of a plurality of orifices formed in spaced rows in the bottom walls of the channels. Temperature differences existing in the molten material within the bushing are evened out by differential cooling of the material as it flows through the channels to the orifices. Cooling is effected in various ways including the placement of solid elongated cooling fins underneath the grooves between channels.
