Abstract: The Control “STIK” is to be used in connection with a ceiling fan for snaring the pull chain and to engage the slide switch to control the rotation of the motor. The “STIK” is comprised of a long pole with an integrated snare hook at one end approximately 45 degrees with reference to the pole. The snare hook is a V-shaped or cone-shaped component that is used to permit the pull chain to slip into the snare hook sufficiently to engage the operation of the chain. The rectangular notch, located just below the snare hook, is used to engage the slide switch actuator and lower or raise it to a desired position for controlling the rotational direction of the motor.

Abstract: A process for varying the density of porous plated metal foams. Especially useful for battery plate applications, a plated foam is coated with a slurry of predetermined size metal power, particularly nickel, and then sintered. The resultant density of the metal foam may be adjusted as needed.

Abstract: A porous nickel electrode substrate having a central high conductivity core sandwiched between two layers of porous conductive material such as nickel foam or nickel felt. The porous conductive material is plated with nickel and then sintered. By selectively controlling the plating of nickel on the porous material, variable conductivities may be designed into the substrate.

Abstract: A sensor for measuring the density of a magnetic porous material such as foam. The sensor includes a load cell connected to a magnet. The magnet is spaced a predetermined distance away from the material. The load sensed by the pull of the magnet is translated into a perceivable density value.

Abstract: The invention provides a method of monitoring reagent levels in aqueous copper electrolytic solutions. To determine the amount of glue present in an electrowinning solution, potential is applied, decreasing in a cathodic direction (more negative) to initiate a first cycle peak. The first cycle peak is compared to a known to determine amount of glue in the solution. Additionally, voltage is cycled between upper and lower voltages to monitor glue/lignosulfonate ratios. Hysteresis and cycle stability are measured at reference voltages and compared to known hysteresis and cycle stability values to monitor glue/lignosulfonate ratio of electrolytic solutions.

Abstract: Ocean bottom mapping is carried out by projecting a sonic pulse in the form f a fan-shaped beam from a vessel toward the ocean floor, receiving echoes by an array of sonic detectors extending athwartship, repeatedly taking instantaneous, simultaneous, snapshot-like samples of all of the detectors in the array, and, by means of a digital computer, applying a beam-forming transform, such as a Fast Fourier Transform, to the samples, thereby producing a spectrum of amplitudes versus angles. The directions of the floor areas from which the snapshot data emanate are determined from refinement of the peaks in the spectrum of amplitudes, and the distances of the same floor areas from the vessel are determined by the time interval between the pulse and the sample. A bottom profile is constructed from the directions and distances so determined. Two alternative techniques for refining and interpreting spectrum data are described.

Abstract: Sponge titanium powder is compacted, advantageously by roll compaction to a density in the range of about 60% to 80% of the density of solid titanium metal, thereafter heat treated in vacuum at about 500.degree. C. to 750.degree. C., cooled in vacuum to 300.degree. C. and quenched to 100.degree. C. to provide a substrate for electrodes useful in electrolytic processes.

Abstract: A cobaltic oxide hydrate is mixed with spent sulfate electrolyte and the slurry is sparged with air to liberate any entrained chloride ions as gaseous chlorine. Thereafter a reducing agent is used to enable dissolution of the cobalt and obtaining of a chloride-free solution from which, after purification, cobalt can be electrowon.

Abstract: A flexible hose line which may be used for loading and unloading oil tankers having a secondary fluid retaining reinforcement carcass to retain leakage and to indicate by radial expansion failure of the main carcass. The secondary carcass may be of high elongation material or may have an angle of lay of the reinforcement to give radial expansion on pressurization.

Abstract: An improved bimetal actuator is disclosed. A thin film resistor is fixed to the high expansion side of a bimetal element and, when energized, generates sufficient heat to actuate the bimetal. The resistor has a serpentine configuration formed by a continuous series of loops, each successive loop having a greater width from the fixed to the free end of the bimetal, to provide differential heating of the bimetal and thus a greater movement of its free end for the power dissipated in the resistor.

Abstract: An electrolyte containing an organic buffering agent is used to electrowin nickel with a comparatively high bite in a diaphragm-free cell.

Abstract: Sulfur-containing nickel is electrodeposited from a chloride electrolyte in a cell wherein each cathode is separated from any adjacent anode by a pair of diaphragms.

Abstract: Novel polyurethanes particularly useful in forming injection molded articles having a good balance of physical properties including, particularly, greater stiffness, low temperature impact and elevated heat distortion resistance are obtained by reacting hydroxyl-terminated polyesters or polylactones having molecular weights greater than about 2800, a cyclic diisocyanate and an aliphatic diol at decreased reaction temperatures.
