Instrumentation Of Multi-Channel Counting Experiments
Recent experience in instrumentation of several nuclear-physics experiments has demonstrated the feasibility of automating the data-acquisition phases of the experiment. Electronic circuits are employed wherever the rate of data flow would be slowed by the use of human operations. Information is selected, temporarily stored, and then recorded in a form suitable for immediate entry into a computer. Experimenters thus freed from the tedious aspects of data collection can devote their time to studying the results of the experiments. Potentially useful nuclear events are first selected by the fast-logic part of the instrumentation. Circuits performing simple logical functions are packaged in modular form for easy grouping into particular coincidence, gating, and mixing configurations. Circuits with slower response times are used for temporary storage and recording operations. Automatic test routines are used to initially align the equipment as well as provide continuous calibration during the experiments. Some of the high-speed circuits are described as well as the methods used to incorporate them into a large counting system.

A Criterion For Vacuum Sparking Designed to Include Both R. F. and D. C.
An empirical relation is presented which represents a boundary between no vacuum sparking and possible vacuum sparking. Metal electrodes and r.f. or d.c. voltages are used. The criterion fits several orders of surface gradient, voltage, gap, and frequency. Current due to field emission is considered necessary for sparking but in addition, energetic particles are required to initiate a cascade process which increases the field emission currents to the point of sparking. An elementary cascade process is outlined, but the data upon which it is based is not fully stated.

Oral History Interview with Richard L. Nielsen, September 4, 2012
The National Museum of the Pacific War presents an oral interview with Richard L. Nielsen. Nielsen joined the Navy in 1960 after two years of college at San Francisco State. Nielsen discusses his father's service aboard liberty ships as a radio operator in the Merchant Marine during WWII in the Pacific. He also shares anecdotes about time in boot camp at San Diego. After boot camp, Nielsen went to hospital corps school. Upon completion of that, he was stationed in the intensive care unit at Oak Knoll Naval Hospital in Oakland, California. He relays an encounter he had with Admiral Nimitz as a patient at the hospital. He also relates an incident in which he traveled with a doctor to Yerba Buena Island to treat Admiral Nimitz at his home the day before he passed away.

INCREASING HEAVY OIL RESERVES IN THE WILMINGTON OIL FIELD THROUGH ADVANCED RESERVOIR CHARACTERIZATION AND THERMAL PRODUCTION TECHNOLOGIES
The overall objective of this project is to increase heavy oil reserves in slope and basin clastic (SBC) reservoirs through the application of advanced reservoir characterization and thermal production technologies. The project involves improving thermal recovery techniques in the Tar Zone of Fault Blocks II-A and V (Tar II-A and Tar V) of the Wilmington Field in Los Angeles County, near Long Beach, California. A primary objective is to transfer technology which can be applied in other heavy oil formations of the Wilmington Field and other SBC reservoirs, including those under waterflood. The thermal recovery operations in the Tar II-A and Tar V have been relatively inefficient because of several producibility problems which are common in SBC reservoirs. Inadequate characterization of the heterogeneous turbidite sands, high permeability thief zones, low gravity oil, and nonuniform distribution of remaining oil have all contributed to poor sweep efficiency, high steam-oil ratios, and early steam breakthrough. Operational problems related to steam breakthrough, high reservoir pressure, and unconsolidated formation sands have caused premature well and downhole equipment failures. In aggregate, these reservoir and operational constraints have resulted in increased operating costs and decreased recoverable reserves. The advanced technologies to be applied include: (1) Develop three-dimensional …

Oral History Interview with Bill Marten, February 4, 2016
The National Museum of the Pacific War presents an oral interview with Bill Marten. Marten joined the Merchant Marine in November 1943. He started as a fireman working as a water tender in the engine room. Marten describes some of his service on tankers crossing the Atlantic. He details an incident where he witnesses another tanker in his convoy explode after it was hit by a torpedo. Marten took part in 12 voyages and eventually left the Merchant Marine in 1948.

Oil and Gas Field Code Master List 1990
This is the ninth annual edition of the Energy Information Administration's (EIA) Oil and Gas Field Code Master List. It reflects data collected through October 1990 and provides standardized field name spellings and codes for all identified oil and/or gas fields in the United States. There are 54,963 field records in this year's Oil and Gas Field Code Master List (FCML). This amounts to 467 more than in last year's report. As it is maintained by EIA, the Master List includes: Field records for each state and county in which a field resides; field records for each offshore area block in the Gulf of Mexico in which a field resides;field records for each alias field name; fields crossing state boundaries that may be assigned different names by the respective state naming authorities.
