Spray coating apparatus having a rotatable workpiece holder

A spray coating apparatus is provided for rotating a workpiece relative to a spray station to obtain a uniform coating of the workpiece. In a typical example, the workpiece comprises a ceramic tile which is to be coated with a ceramic coating and the tile is to be used as a reusable component of the thermal protection system for a space shuttle. The apparatus for rotating the workpiece includes a base support having a first rotatable stage for rotation in the horizontal plane and a second rotatable stage for rotation in a second plane inclined at an angle, such as 45 degrees, to the horizontal plane and the workpiece is supported on this second stage. Thus the workpiece is rotatable in both of two planes of rotation

Granite State Poll for New Hampshire Estuaries Project

The University of New Hampshire Survey Center included a question on its July 2004 Granite State Poll for the New Hampshire Estuaries Project. The major purposes of these questions were to assess the knowledge of New Hampshire residents concerning the meaning of an estuary. Five hundred and nine (509) New Hampshire adults were interviewed by telephone between July 6 and July 20, 2004

Sound separation probe

Probe separates sound waves from turbulent flow pressure fluctuations in ducted airstreams by using principle that sound waves and turbulent flow pressure perturbations travel at different velocities

Irrelevant Exceptional Divisors for Curves on a Smooth Surface

Given a singular curve on a smooth surface, we determine which exceptional divisors on the minimal resolution of that curve contribute toward its jumping numbers.Comment: Added reference to Favre & Jonsson and a slight extension of the comment immediately following Definition 2.

Embeddings of rearrangement invariant spaces that are not strictly singular

We give partial answers to the following conjecture: the natural embedding of a rearrangement invariant space E into L_1([0,1]) is strictly singular if and only if G does not embed into E continuously, where G is the closure of the simple functions in the Orlicz space L_Phi with Phi(x) = exp(x^2)-1.Comment: Also available at http://www.math.missouri.edu/~stephen/preprint

Alternative financial service providers and the spatial void hypothesis

This paper examines the use of alternative financial service providers (AFSPs) such as check-cashing outlets and pawnshops in Philadelphia, Montgomery, Delaware, and Allegheny counties. Also explores whether these providers are disproportionately serving minority and low-income areas.

Alternative financial service providers and the spatial void hypothesis: the case of New Jersey and Delaware

This paper continues the use of the spatial void hypothesis methodology to analyze the location of alternative financial service providers, such as check cashing outlets and pawn shops, in New Castle County, Delaware, and Atlantic, Mercer, Monmouth, and Passaic counties in New Jersey. Also explores whether these providers are disproportionately serving minority and low-income areas.

Reusable silica surface-insulation material

Material was specifically developed for manufacture of insulating tiles, but it can be molded into other shapes as required. Basic raw materials are high-purity silica fiber, fumed-silica powder, and reagent-grade starch. Only purest materials are used, and care must be taken to avoid contamination during processing
