摘要:
An electrical magnet having a support structure which comprises a flat plate of structural material and abutment means engaging the conductor of the electrical magnet to the plate. The abutment means may comprise a groove in a face of the plate which receives and restrains the conductor, a raised flange on a face of the plate which forms such a groove, or a flange which extends around and is affixed to the periphery of the plate and which is formed to fit tightly over a coiled conductor. When current is flowing in the conductor of the magnet, all points on the conductor will experience a magnetically induced force, one component of which is in an outward direction parallel to the plane of the plate. The abutment means opposes this component of the force and transmits it to the plate, which is consequently stressed in tension in two dimensions. Several individual magnets supported by the support structure may be combined to form large magnets having solenoidal, toroidal or other configurations. The magnets may be built with a normal or a superconducting electrical conductor.

The removal and recovery of mercuric materials from dilute solutions by treating mercuric halide in aqueous solution with a solvent solution of a primary, secondary and preferably tertiary alkyl amine having from 6-18 carbon atoms in the alkyl groups, at a pH within the range of 0.5-3 to extract the mercury from the aqueous phase into the organic phase and then extracting the mercuric complex from the organic phase to an aqueous phase by treatment with an aqueous phase at a pH within the range of 913.
摘要:
A multimode oscillator is disclosed, comprising an array of interconnected oscillator elements distributed over at least two dimensions. The oscillator elements include a grid or network of impedance elements. Three or more inductive (capacitive) elements may radiate from each junction point in the grid, and a capacitive (inductive) element may be shunted to ground from each junction point. Other arrangements of impedance elements are also possible. For pattern recognition, the oscillator elements may also include radiation sensitive elements for selectively controlling the activation of the oscillator elements. Thus, the incident pattern of light, infrared, ultraviolet, X-ray, sound or other radiation controls the number and selection of the simultaneous modes of oscillation in the multimode oscillator. The radiation sensitive elements may be shunted across the capacitive, inductive or other impedance elements and may take the form of radiation sensitive transistors, diodes, resistors, thermistors, switches, microphones or other devices. The multimode oscillator may be either passive or active. Sustained oscillations may be produced in a passive multimode oscillator by providing feedback means between the output and input of the oscillator. An active multimode oscillator employs active elements capable of sustaining the oscillations in the oscillator. Such active elements may include various negative resistance elements such as tunnel diodes. For pattern recognition, active elements may be employed which are also radiation sensitive. Alternatively, the multimode oscillator elements may include both active elements and radiation sensitive elements arranged to control the activation of the active elements. The multimode oscillator may utilize superconductive elements which may be arranged to form a superconductive grid or network to provide an array of inductive elements. The capacitive elements may be provided by the distributed capacitance between the superconductive grid and a superconductive ground plate or surface.

摘要:
Method for controlling number of nodules per unit volume in malleable and ductile irons by the incorporation of both titanium and tellurium as essential components in the range of 0.003 to 0.05 percent by weight titanium with the tellurium being present in the ratio of 1 part by weight tellurium to 10 to 50 parts by weight titanium. Titanium may be replaced in whole or in part with equivalent amounts of niobium, vanadium, or aluminum. Tellurium may be replaced in whole or in part with equivalent amounts of antimony or rare earth metals.
