Abstract: A resinous protective coating useful in the manufacture of printed circuit boards with circuit patterns having a resolution of at least 0.25 mm lines and spaces thereon. The protective coating comprises resins dissolved in solvents, wherein the coating upon being subjected to heat goes from a high viscosity solution to a gel and then to a solid or from a soft "gel-like" state into a solid. The protective coating is resistant to copper electroplating baths, adheres to insulating substrates, adhesive coated base materials as well as metallic substrates and is capable of withstanding the thermal shock of dip soldering.

Abstract: Betaines containing the pyridine nucleus, some of which are novel per se, are dissolved in sea water or formation water, the concentration of betaine being from 200 to 100,000 ppm, to give a surfactant solution suitable for displacing crude oil from a formation in an enhanced oil recovery process. These betaines have low interfacial tension (against oil), a high tolerance towards divalent metal ions and good temperature stability as compared with betaines previously proposed for enhanced oil recovery.

Abstract: A self-contained or boxless electrical wiring device, such as a receptacle or switch, includes a body adapted to be mounted in an aperture in the wall of a building or a mobile home. The body houses wire grasping terminals for connection with the wires of electrical cable without requiring the stripping of insulation. Interior partitions support terminal members into which the insulated cable conductors are forced for terminating the device. The partitions are integrally formed with the front face and side walls of the body in a configuration which is readily molded. Mounting members, in the form of mounting pawls or crimp mounting members are formed at each end to permit installation near wall studs. The body is closed by a back cover having projections for driving the wires into the terminals, the cover being releasably secured via legs which engage the sidewalls.

Abstract: A process for making substrates for interconnecting components in which a filament is applied and affixed to a base in a pre-programmed pattern, the base surface and applied filaments are coated with a coating and the coating is hardened to form a substantially flat surface over the base and filaments. The coated base is then positioned on a table movable along "x" and "y" axes and the coated base is positioned under a high energy beam at pre-programmed points on the applied filament pattern and access openings are formed in the coating on the base at such points to expose the filament at each such point so that the exposed filament can be interfaced with the exposed surface of the coated base and articles for mounting and interconnecting components formed thereby.

Abstract: A method for forming a three-dimensional network containing encapsulated organic material comprises reacting a functionalized polymer and a complementary functional cross-linking agent in the presence of the organic material. The method may be used for recovering oil spilled on sea or land, for treating organic wastes or preventing leakage of oil from tanks or pipelines.

Abstract: Betaines containing the morpholine nucleus, some of which are novel per se, are dissolved in sea water or formation water, the concentration of betaine being from 200 to 100,000 ppm to give a surfactant solution suitable for displacing crude oil from a formation in an enhanced oil recovery process. Included in the solution can be an anionic surfactant containing in its structure an ethoxylated benzene ring which shows a synergistic effect with the betaine in lowering the interfacial tension of the surfactant solution against oil. These betaines have high tolerance towards divalent metal cations and high temperature stability as compared with betaines previously proposed for enhanced oil recovery.

Abstract: Burner for a concealed flare has a fuel gas supply pipe having a low resistance to upward aspirated air flow. The pipe has outlets directing fuel gas onto adjacent plates which cause spreading and mixing of fuel gas with aspirated air. The angle of fuel gas impingement on the plates is 1.degree. to 55.degree. and the plates have a flame retaining top edge.

Abstract: A dispenser package for flowable substances of the type where the flowable product is contained within a flexible pouch adhered to a relatively stiff material and may be opened along a fault line or cut pattern scored in the relatively stiff material with one hand by folding the stiff ends toward one another into a "V" shape containing one or more dimples, pyramidal shapes or other protrusions on the fault line or fault area. The protrusions not only increase and concentrate the stress forces, so that even very tough, high barrier materials may be used in constructing the package and will rupture at the protrusions by the aforesaid folding motion, but also control both the aperture shape and flow direction of the flowable substance as it is dispensed. The ability to make the package of tough materials enables the package to contain substances under pressure which subsequently will be dispensed.

The innermost surface of the annular chamber (3) forms a secondary loading tube (6) which has a Coanda surface (12) at its lower end. A slot (11) is provided between the innermost surface of the gas supply chamber (3) and the Coanda surface (12) to form a Coanda nozzle.The apparatus is particularly suitable for use in loading catalyst to a reactor and achieving a high packing density with a low voidage.In use, particles falling near the center of the primary loading tube are entrained and separated by gas emerging from the Coanda nozzle and have a high velocity imparted to them.
