Abstract

An apparatus and method generate oxygen gas from sodium percarbonate and water including seawater. The apparatus includes a chamber, a valve system, and an output port. The valve system controls combining a quantity of the sodium percarbonate, a quantity of the water, a quantity of potassium iodide, and optionally a quantity of sodium sulfate decahydrate. A chemical reaction between the sodium percarbonate and the water in the chamber generates oxygen gas, which is output at an output port from the chamber. The potassium iodide is a catalyst for the chemical reaction and optionally the sodium sulfate decahydrate is a temperature moderator for the chemical reaction. A ratio between the water and the sodium percarbonate is in a range of 2.5 to 8 by weight. A ratio of the potassium iodide per liter of the water yields a molarity in a range of 0.25 to 1.25.

Abstract

A sandwich cable fairing designed for attachment to cables that are towed at operational speeds by marine vessels. The sandwich cable fairing has a design that combines layers of elastic and damping materials. The fairing dampens the vibration caused when the cable is towed at operational speeds. The outer layers (“bread”) of the fairing are made from a material with a modulus of elasticity that provides a desired amount of stiffness. In the middle of the sandwich cable fairing is damping layer made from a viscoelastic material. The layering of materials allows the fairing to have the flexibility to be crushed by cable equipment while maintaining the requisite stiffness to reducing flapping and the resulting vibration.

Abstract

An antenna arrangement has radiation modes for antennas distributed across a geometrical shape, which is a bounded volume in three dimensions or a conformal surface of the bounded volume. A signal network couples between an electrical signal and the antennas with a taper along a selected dimension selected from the three dimensions of the bounded volume. The taper is specified by a selected dimension and a selected mode, which is selected from the radiation modes. Basis polynomials are indexed over the radiation modes and a specified basis polynomial is indexed at the selected mode. The specified basis polynomial gives the taper of an amplitude of the electrical signal at each of the antennas. An operating method determines a respective array factor for each distinct combination of one of the three dimensions and one of the radiation modes, and then selects the distinct combination with a desired array factor.

Abstract

Disclosed are apparatus and methods for sensing and measurement of magnetic fields that are insensitive to temperature, and respond linearly to the magnitude of the magnetic field. In particular, the apparatus and methods include the use of a resistance network including at least one fluorinated graphene foam (FGF) magnetoresistive device. Measurement of a voltage drop across at least one FGF magnetoresistive device is correlated to either merely the presence of a magnetic field or for measurement of at least a scalar magnitude value of the magnetic field. The use of FGF affords both temperature-insensitivity and linear magnetic field responsivity.

Abstract

A propeller pitch adjustment assembly is provided with a base hub operatively connected by blade shafts to propeller blades in which each blade rotates about an axis of each shaft. Each blade shaft is radially disposed about a propeller drive shaft and parallel to a pressure flange of a base hub spring plate. The spring plate counterforces the blade rotation with a lever screw that impacts the plate. An opposing spring transfers a load to the plate. The equilibrium position of the plate is determined by the spring force on the lever and a counteracting force exerted on the lever by a lift force generated by fluid flow over a propeller blade. A capping mechanism can provide a preload to the spring. A force exerted by the lift of the blade on the lever screw results in a blade pitch change.

Abstract

Exemplary inventive practice improves the taxiing dynamics of a seaplane by propulsively imparting roll moments so as to continually encourage levelness of the two wings, thereby maintaining both wings completely above (out of) the water. Two matching motor-driven propellers are correspondingly positioned at or near the wingtips. A computer receives sensory motion inputs and transmits sequential commands that continually adjust the respective propulsive forces of the wingtip propellers by effecting equal and opposite changes in their respective rotational speeds. An increase in one wingtip propeller's rotational speed is concomitant a decrease in the other wingtip propeller's rotational speed, wherein the increase and the decrease are of the same magnitude. The seaplane rolls upward on the wing whose wingtip propeller is increasing in rotational speed. Control of the seaplane's rolling motion is thus enabled by a sustained propulsive equilibrium between the two wingtip propellers.

The invention is a system for the in-situ monitoring of additive manufacturing. The system, without pre-calibration of a test sample, utilizes ultrasonic waves to conduct a layer-by-layer analysis of a three-dimensional component as it is being developed on a build plate.

Similarities or differences in baseline frequencies are used to validate the integrity of the layers of the component, and also to determine if structural inconsistencies exists. Based on these determinations, the system decides whether to continue printing or to halt printing.
