A feedback-stabilized vertical-deflection circuit

IEEE Transactions on Broadcast and Television Receivers, 1967
This paper describes a feedback-stabilized vertical-deflection circuit that makes use of a transistor oscillator to drive an output tube. The circuit possesses a few innovations that overcome some of the deficiencies that exist in conventional vertical-deflection circuits.

On the gravimetric undulations of the geoid and the deflections of the vertical

Geofisica pura e applicata, 1958
The author mentions the aims of the World-wide gravity project he established in the Ohio State University in Columbus, in 1950. He outlines the practical procedure of the gravimetric computations of the undulationsN and the vertical deflection components ξ and η and emphasizes that only by the global international cooperation and additional gravity ...

Yoke Analog Vertical Deflection Systems

IEEE Transactions on Broadcast and Television Receivers, 1965
The yoke analog consists of a series RC network connected across the yoke. If the time constant of this network is exactly equal to the L/R time constant of the yoke, the voltage across the resistor of the RC network will, at all times, be the same as the voltage across the inductive component of the yoke.

Method to Compute the Vertical Deflection Components

2010
To make a more exact mathematical model of the global atmosphere circulation and to improve the weather forecast one needs to take into account the Vertical Deflection Components (VDCs). The required accuracy for these tasks is 1–2′′ now and 0.4–1.0′′ in future.

Deflections of the vertical from gravity anomalies

Eos, Transactions American Geophysical Union, 1947
With the increasing number of surveys based on astronomical coordinates and with loran stations established on oceanic islands far from the mainland and its geodetic control, there has been an increasing interest in deflections of the vertical.Some of those who have a professional interest in deflections of the vertical but who have not analyzed the ...

Gravimetric deflections of the vertical by digital computer

1963
A digital computer program has been developed to calculate plumb-line deflections from gravity data. A region of 1,200 X 1,200 km for which free air anomalies were available was subdivided into units of 50 X 50 km. With n denoting the number of points per unit, each unit was represented by one gravity anomaly calculated as an average in cases where 0 ...

Lunar deflections of the vertical and their elementary interpretation

Studia Geophysica et Geodaetica, 1972
The selenopotential was determined at the Apollo 12 landing site (A12) using the selenocentric constant, Stokes' constants of the Moon up to n=13, the angular velocity of rotation of the Moon and the value of gravity directly observed at A12. Using and the constants mentioned above, the radius-vector of the equiselenopotential surface passing ...
