Escaping in the “Tender, Blue Haze of Evening”: The Morro Castle and Cruising as a Form of Leisure in 1930s America

The paper demonstrates a microhistory approach to the development of cruising as a form of leisure in the early twentieth century of American history. Using the 1934 Morro Castle disaster and the subsequent attention the ship and its survivors received, this paper provides a window into an unexplored topic of American leisure. This paper is unique in its finding because the disaster provided numerous firsthand accounts of cruising in the 1930s. The findings illustrate that this form of leisure was directly connected to larger events and trends of the time, including the Great Depression, Prohibition, and America’s Cuban connection. Cruising as a form of leisure, thus, developed out of a social and cultural demand, illustrating escapism in a tumultuous period

Tube welding and brazing

Brochures outline the tools, equipment, materials, and techniques used for joining tubes by automatic and semiautomatic welding and brazing. A few of the metals being joined are stainless steels of various diameters and thickness. Techniques have been developed for on-site or work-bench repair

Low gravity exothermic heating/cooling apparatus

A low gravity exothermic heating/cooling apparatus is disclosed for processing materials in space which includes an insulated casing and a sample support carried within the casing which support a sample container. An exothermic heat source includes a plurality of segments of exothermic material stacked one upon another to produce a desired temperature profile when ignited. The sample container is arranged within the core of the stacked exothermic heating material. Igniters are spaced vertically along the axis of the heating material to ignite the exothermic material at spaced points to provide total rapid burn and release of heat. To rapidly cool and quench the heat, a source of liquid carbon dixoide is provided which is conveyed through a conduit and a metering orifice into a distribution manifold where the carbon dioxide is gasified and dispersed around the exothermic heating material and the sample container via tubes for rapidly cooling the material sample

Willem Blaeu\u27s \u27Asia noviter delineata\u27: Expressions of Power through Naval Might and Natural Knowledge in Dutch Mapmaking

This paper situates Dutch mapmaker Willem Blaeu’s Asia noviter delineata—part of the Stuckenberg Map Collection in the Gettysburg College Special Collections—within the larger framework of Renaissance thought and a shifting colonial balance of power. The map’s pictorial marginalia expresses a Dutch quest for empirical knowledge that echoed contemporary cabinets of curiosities throughout early modern Europe. Similar to these cabinets, Blaeu’s map can be seen as a cartographic teatro mundi, used to propagate Dutch hegemony through both a robust naval presence and an expanding geographic and natural knowledge of the world

Rapid melt/quench furnace using commercially available hardware

This report describes an off-the-shelf Orbital Tube Welder that can be easily used to melt and resolidify almost any electrically conductive material. This can be done on a KC-135 Aircraft within the microgravity period of one parabola. Melt sizes 3 mm diameter by 10 mm length and larger are feasible with most if not all materials. A highly reproducible, controlled, programmable heat and cool cycle can be provided. Sample measurements would have to be developed and could be as sophisticated or as simple as desired. These could include: optical and thermocouple temperature measurements, Peltier pulser for marking the solidification fronts, dimensional changes and whatever. Sample heat flows could be fixed over a very wide range being limited mostly by the cooling period, the desired sample size, and the 20 sec microgravity period of the KC-135 Aircraft parabola

F-104 low-gravity calibration tests for materials processing in space precursory experiments

A precursory low-gravity flight experiment in an F-104 aircraft was conducted to check out the vehicle as a suitable flight test carrier for microgravity experiments. Calibration experiment verification tests in the F-104 were completed. Three flight parabolas were flown. The test data shows all the test parameters recorded by telemetry to have reasonable values. Photographic records are clear and distinct.Solidification modes were the same as those observed in other low gravity environments. The F-104 has been proven to be a useful test bed for low gravity experiments which require less than 60 seconds of low g time

Arc/gas electrode

A gas/arc electrode is disclosed for use under vacuum conditions where a first housing encloses a second housing, with an end of the second housing extending through an opening in the first housing and having an outlet orifice. Provisions are made for circulating a coolant through the first housing to surround and cool the second housing. An electrical current and a gas, such as argon, as passed through the second housing, with the current flowing through a narrow stream of the ionized gas flowing through the outlet orifice to a workpiece to be treated. The second housing forms a chamber which has a cross sectional area, in a plane perpendicular to the direction of gas flow, of at least ten times the cross sectional area of the outlet orifice such that a gas pressure can be maintained in the chamber to reduce erosion of the chamber walls

Exothermic furnace module

An exothermic furnace module is disclosed for processing materials in space which includes an insulated casing and a sample support, carried within the casing which supports a sample container. An exothermic heat source includes a plurality of segments of exothermic material stacked one upon another to produce a desired temperature profile when ignited. The exothermic material segments are constructed in the form of an annular element having a recess opening which defines an open central core throughout the vertical axis of the stacked exothermic material. The sample container is arranged within the core of the stacked exothermic heating material

Vacuum vapor deposition: A spinoff of space welding development

A vapor deposition process has been defined through a spinoff effort of space welding development. In this development for welding in a space environment, a hollow electrode was used to add gas precisely at the welding arc. This provides gas for ionization which carries the welding arc current. During this welding development metal vapor coatings were observed. These coatings are unique in that they are produced by a new process. Some coatings produced and the potential of this new and innovative vapor deposition process are characterized. Advantages over prior art are discussed

The Minority Experience at Gettysburg College: The Hanson Years (1961-1977)

The years of C. Arnold Hanson’s term as president at Gettysburg College were years of turbulence, change, and challenge. Rising to the position of president in 1961, in the dawning of a dynamic era of modern American history, C. A. Hanson served well into the middle of the next decade, during which time he helped guide Gettysburg College through some of its most trying and vital changes. This was the era of the hippie and the free thinker, the era of the Women’s and Civil Rights Movements, the era of Vietnam and anti-war protests, the era that shaped modern American society and culture. During this period, one of the areas in which the most dramatic changes occurred was in the sphere of Civil Rights; Gettysburg was far from the forefront in dealing with bigotry, but it did confront the race issue. As this occurred on the national scale, efforts were made at Gettysburg to follow suit. Sadly, this was often difficult and unsuccessful, occurring “in fits and starts.” During C. A. Hanson’s tenure as president, minorities experienced discrimination as they pursued equal opportunities in education, faculty and administrators struggled to construct a successful strategy for integration, students brought down racial barriers through interaction, and above all, many African Americans demonstrated extraordinary strength of character in their fight for equality and acceptance into the Gettysburg College community.
