Abstract: ABSTRACT         In an overhead transmission line comprising a bundle of conductors, each span of the line defining a torsionally oscillatory system, the mass distribution of the system with respect to the central torsional axis is asymmetrical.  In this way the torsional stiffness of the bundle is modified so as to raise the natural frequency of oscillation in the tors-ional mode substantially above the natural frequency of oscil-lation in the transverse mode, thereby to prevent coupling between the modes and so prevent build-up of galloping vibrations.

Title: Post growth adjustment of magnetic propeties of germanium substituted garnet compositions
Inventor: HEINZ DAVID M
IPC: H01F10/24
Filed: 1976-08-30
Granted: 1980-06-17
Abstract: ABSTRACT OF THE DISCLOSURE The magnetic properties of germanium substituted garnet compositions are made adjustable by heat treatment after crystal growth by inclusion in the garnet composition of a small percentage of adjustment-permitting ions whose distribution between tetrahedral and octahedral lattice sites can be reversibly changed by post-growth heat treatment of the garnet material. Post growth annealing of the film results in redistribution of adjustment-permitting ions between tetrahedral and octahedral lattice sites with a consequent change in magnetic properties.

Abstract: NUCLEATING DEVICE AND METHOD OF PREPARING SAME     Abstract of the Disclosure A nucleating device is formed of a material, such as glass, having a highly disordered lattice which has been processed to produce microcavities therein each having a size typically in the order of less than 1000 Angstroms.  Solid crystals are disposed in the microcavities to aid in the crystal seeding and thereby promote crystallization of a melt or solution of a compound without supercooling.  In one embodiment the nucleating device is in the form of a glass float covered with glass fibers processed so as to have microcavities with said crystals disposed in the micro-cavities.  Advantageously, the crystals do not have to have the same chemical structure as the compound being crystallized.         According to the method of this invention, micro-cavities are formed in a substance having highly disordered lattices by removing parts of the lattices as by leaching.          At least a portion of the microcavities are then filled with solid crystals.  The nucleating device may be in the form of a glass float or it may be in the form of glass fibers which surround the float.

Abstract: ABSTRACT     In a method of arc welding under water or at superatmospheric pressure (or both) the weld is made in a chamber containing a gaseous atmosphere.  The weld metal is deposited from flux-cored welding wire whose core contains strong deoxidant(s) such as aluminium, magnesium, titanium, zirconium, lithium, and calcium.  A shielding gas containing a selected proportion of oxygen or oxygen-containing gas but consisting mainly of an inert gas such as argon or helium is employed to surround the arc.  The shielding gas may be constituted by the atmosphere in the chamber or alternatively it may be fed to the welding torch with the welding wire and issue from the torch in the form of an annular stream surrounding the wire as the wire emerges from the torch.  The invention makes possible the achievement of sound welds having achievable mechanical and metallurgical properties at depths of water down to 450 feet or below.

Abstract: ABSTRACT OF THE DISCLOSURE:      A louver assembly has a plurality of louver blades and pivot shafts pivotally supported for adjustable movement between open and closed position in a frame which includes two opposed vertical side frame members.  A jamb seal between each side frame member and the adjacent ends of the louver blades prevents air flow around the ends of the blades when the blades are closed.  Each jamb seal includes a panel installed between a side frame member and the transverse louver blade ends facing that side frame member.  Each panel includes a rigid but flexible, substantially flat, face portion adapted for flush contact with the blade ends when the blades are closed, and two outer and two inner elongated rigid supporting ribs integral with respect to the fact por-tion and extending away from that side of the face portion opposite the blades.  The edges of these ribs away from the face portion are provided from top to bottom with integral elastic sealing cushions.  Each outer rib has a thin resilient air seal flipper being in sealing relation to its side frame member.  The louver blades tend to force each panel towards its associated side frame member, placing the panels and the cushions under compression.  This completely seals the space between the blade ends and their associated side frame members when the blades are closed.  Transverse slots are provided halfway through the panels to receive the louver pivot shafts as the panels are installed by sliding them between the blade ends and the side frame members.

Abstract: ABSTRACT OF THE DISCLOSURE    The invention contemplates improved hydraulic-pressure control apparatus which will proportionally reflect input-signal changes governing a wide range of output pressures.          Use of a separate preamplifier stage, between a signal-pressure stage and a power stage, enables the signal pressure to remain essentially unaffected by load reaction or other transients at the power stage.  In the forms described, an input electrical signal determines a step-function program of signal-pressure levels, and the power stage includes a relief valve which so diverts system-line flow to a sump as to assure quick and accurate response of system-line pressure to the instantaneous input electrical-signal level, all without system-pressure overshoot.
