High-speed digital plotter

Modified typewriter mechanism with standard logic components provides digital plot of output of multichannel analyzer. Unit plots irregular curves at approximately 14 channels per second, and smooth curves at over 25 channels per second, and is not subject to analog error or drift

Annual Survey of Virginia Law: Augmented Estate System: An Overview

The New Year 1991 will bring in an entirely new system of property rights for surviving spouses in Virginia. As of the end of 1990, the centuries-old concepts of dower and curtesy will disappear from the Code of Virginia (the Code ). The current will renunciation and spouse\u27s election provisions of estate law also will be scrapped. House Bill No. 808 replaces those historic concepts with an augmented estate system modeled after the Uniform Probate Code (the U.P.C. ), but having several features unique to the Commonwealth. This article examines the mechanics of the new system, with particular emphasis on features that may require both conveyancers and estate planners to rethink traditional procedures and planning techniques

A Quasi-Global Presentation of TIROS III Radiation Data

The TIROS III meteorological satellite was equipped with a five-channel medium resolution radiometer to measure the reflected solar radiation as well as the infrared emission of the earth-atmosphere system in five different spectral regions (Reference 1). According to the initial design of this radiation experiment, one of the most useful applications of the infrared measurements was to be the derivation of day and nighttime cloudiness from Channel 2, which was sensitive within the atmospheric "window" region (8 to 12 microns). Several authors already have demonstrated and discussed the principal usefulness of these data for this particular purpose (References 2, 3, and 4). This present study was performed to investigate and demonstrate the utility of the TIROS radiation data for global synoptic analyses

Current flow in a plasma caused by dielectric breakdown

Spacecraft with a thin dielectric coating on the outer surface of the structure which are biased (-200 V) negative relative to the atmospheric plasma are susceptible to dielectric breakdown. This paper will present experimental tests designed to measure the electron current flow from the structure through the plasma during the arc. The current path was examined in three parts: the electrons supplied through the structure and the arc to the outer structure, the expansion of the arc into the ambient plasma, and the return current through the ambient plasma. The measured electron current either flowing from the plasma or supplied to the plasma by the arc in each case was compared to the random thermal electron current which could be collected. The results of the tests show a spacecraft is capable of supporting arcs with peak currents greater than thermal electron currents, and these currents will be dependent upon the amount of stored charge in the structure (i.e., the structure's surface area and dielectric thickness). Also, the results of these tests show that it is possible for structures with a self capacitance of 10 microFarads to see peak currents of 90 A and structures with 1000 microFarads (i.e., capacitance of one Space Station Freedom module) to produce peak currents of 1000 A

Wills, Trusts, and Estates

The 2019 Virginia General Assembly did not enact any major new legislation, but it did pass several significant amendments. Among the most useful was an amendment to the Virginia Uniform Transfers to Minors Act which extended the maximum age for custodianships from twenty-one to twenty-five. The legislature also decided to cease imposing income taxes on estates and trusts whose sole connection to the Commonwealth is that they are being administered here. It responded to two recent court cases involving the required execution formalities for leases and the right to award attorneys’ fees in actions involving an agent’s breach of fiduciary duty under a power of attorney. Among other legislative actions, the General Assembly modernized the recordation tax exemption for certain deeds of distribution; dealt with issues affecting Virginia’s small estate, wrongful death, and property tax exemption statutes; made it easier for financial institutions to combat financial exploitation of the elderly; strengthened the enforcement of reporting requirements for guardians; and protected circuit court clerks who disclose probate tax return information to the commissioner of accounts or who destroy wills they have been holding for 100 years or more
