Three metal sheets, having prenotched edges, are interlocked as they are unrolled from three feed rollers which form a triangle. The apparatus is relatively small, and the sheets can be erected into a rigid triangular boom of considerable length.
Cylindrical dipole antenna field in compressible isotropic plasma, assuming triangular current distribution and deriving input impedance formula
Physical adsorption isotherm based on triangular site model, including neighbor interactions via Lennard-Jones intermolecular potentials
Triangular aluminum tool kit, filled with polyurethane is constructed to receive various tools and hold them in a snug but quick-release fit as an aid to heavily gloved workers. The kit is designed to allow mounting within easily accessable reach and to provide protection of the tools during storage.
Photomicrographic method determines mean particle diameters of monodisperse polystyrene latexes. Many diameters are measured simultaneously by measuring row lengths of particles in a triangular array at a glass-oil interface. The method provides size standards for electronic particle counters and prevents distortions, softening, and flattening.
Generator produces dynamic test signals in the range from 0.0001 and 10 to the minus 12th power amperes. It involves an extension of the technique of applying a triangular voltage waveform to a small capacitor to obtain a square-wave output current. The effects of stray capacitance are minimized by appropriate shielding.
Calculation of sawtooth voltage oscillations of triangular shape for pulse width modulation pulse shaping circuit
Elliptic restricted three-body problem solved for eigenvalues and orbital series solutions of Lagrangian triangular point
Oscillating mass flow characteristics in modified Moore variometer configuration for step, triangular and infrasonic functions
Boundary migration in melt-grown bicrystals of KCl containing pure twist boundaries was investigated. The experiments involve the use of bicrystal specimens in the shape of right-triangular prisms with the boundary parallel to one side.
Wideband FM signal generation without frequency deviation or modulation frequency limitations by wave shaping FM triangular wave, discussing transmitter receiver distortion
Triangular plate bending element using Herrmann variational method, deriving matrices for finite elements
Cookie cutter device initiates production of identical, double-contoured fiber glass elements used as shock absorbers. Three-bladed edges convert triangular honeycomb elements into hexagonal shapes which are then stamped to desired length by concave and convex dies. Sandpaper smoothing completes the process.
Fourier transform hologram camera increases the velocity range for holography by a factor of 10 to 1000. Two different optical systems, using a triangular arrangement of beam splitters and a mirror to illuminate the object from two directions, are investigated.
Triangular cutting tool uses carbide tips for notching heat-treated or abrasive materials, and alloys subjected to high structural stresses. The tool is rigidly mounted in a slot of mating contour to prevent deflection during cutting of tensile specimens. No other expensive machine equipment is required.
Bidirectional reflectance of three dimensional surfaces described by diffuse triangular subareas network for spacecraft thermal design, giving numerical technique
Love wave propagation in layers with irregular boundaries, investigating scattered field to determine reflection from triangular notch
Oscillator generates symmetrical triangular waveform when inverting and noninverting inputs are equal. Oscillator portion of circuit has integrated circuit, high-performance operational amplifier wired as differential integrator, and two silicon controlled rectifiers.
