Introduction Investment casting is a manufacturing process that can be traced back over 5,000 years to ancient Egypt and China. It is utilized to cast a wide variety of items, including high- quality, high-performance industrial parts. -
A Replica of the Stretch Clock Recently Reinstated at the West End of Independence Hall
A replica of the Stretch clock recently reinstated at the west end of Independence Hall. (Photograph taken by the author in summer of 197J.) THE Pennsylvania Magazine OF HISTORY AND BIOGRAPHY The Stretch Qlock and its "Bell at the State House URING the spring of 1973, workmen completed the construc- tion of a replica of a large clock dial and masonry clock D case at the west end of Independence Hall in Philadelphia, the original of which had been installed there in 1753 by a local clockmaker, Thomas Stretch. That equipment, which resembled a giant grandfather's clock, had been removed in about 1830, with no other subsequent effort having been made to reconstruct it. It therefore seems an opportune time to assemble the scattered in- formation regarding the history of that clock and its bell and to present their stories. The acquisition of the original clock and bell by the Pennsylvania colonial Assembly is closely related to the acquisition of the Liberty Bell. Because of this, most historians have tended to focus their writings on that more famous bell, and to pay but little attention to the hard-working, more durable, and equally large clock bell. They have also had a tendency either to claim or imply that the Liberty Bell and the clock bell had been procured in connection with a plan to celebrate the fiftieth anniversary, or "Jubilee Year," of the granting of the Charter of Privileges to the colony by William Penn. But, with one exception, nothing has been found among the surviving records which would support such a contention. -

Post-9/11 Brown and the Politics of Intercultural Improvisation A
UNIVERSITY OF CALIFORNIA RIVERSIDE “Sound Come-Unity”: Post-9/11 Brown and the Politics of Intercultural Improvisation A Dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Music by Dhirendra Mikhail Panikker September 2019 Dissertation Committee: Dr. Deborah Wong, Chairperson Dr. Robin D.G. Kelley Dr. René T.A. Lysloff Dr. Liz Przybylski Copyright by Dhirendra Mikhail Panikker 2019 The Dissertation of Dhirendra Mikhail Panikker is approved: Committee Chairperson University of California, Riverside Acknowledgments Writing can feel like a solitary pursuit. It is a form of intellectual labor that demands individual willpower and sheer mental grit. But like improvisation, it is also a fundamentally social act. Writing this dissertation has been a collaborative process emerging through countless interactions across musical, academic, and familial circles. This work exceeds my role as individual author. It is the creative product of many voices. First and foremost, I want to thank my advisor, Professor Deborah Wong. I can’t possibly express how much she has done for me. Deborah has helped deepen my critical and ethnographic chops through thoughtful guidance and collaborative study. She models the kind of engaged and political work we all should be doing as scholars. But it all of the unseen moments of selfless labor that defines her commitment as a mentor: countless letters of recommendations, conference paper coachings, last minute grant reminders. Deborah’s voice can be found across every page. I am indebted to the musicians without whom my dissertation would not be possible. Priya Gopal, Vijay Iyer, Amir ElSaffar, and Hafez Modirzadeh gave so much of their time and energy to this project. -
Campaign Fact Book Former Whitechapel Bell Foundry Site Whitechapel, London
Campaign Fact Book Former Whitechapel Bell Foundry Site Whitechapel, London Compiled January 2020 Whitechapel Bell Foundry: a matter of national importance This fact book has been compiled to capture the breadth of the campaign to save the site of the Whitechapel Bell Foundry, which is currently threatened by a proposal for conversion into a boutique hotel. Re-Form Heritage; Factum Foundation; numerous community, heritage and bellringing organisations; and thousands of individuals have contributed to and driven this campaign, which is working to: reinstate modern and sustainable foundry activity on the site preserve and record heritage skills integrate new technologies with traditional foundry techniques maintain and build pride in Whitechapel’s bell founding heritage The site of the Whitechapel Bell Foundry is Britain’s oldest single-purpose industrial building where for generations bells such as Big Ben, the Liberty Bell, Bow Bells and many of the world’s great bells were made. Bells made in Whitechapel have become the voices of nations, marking the world’s celebrations and sorrows and representing principles of emancipation, freedom of expression and justice. As such these buildings and the uses that have for centuries gone on within them represent some of the most important intangible cultural heritage and are therefore of international significance. Once the use of the site as a foundry has gone it has gone forever. The potential impact of this loss has led to considerable concern and opposition being expressed on an unprecedented scale within the local area, nationally and, indeed, internationally. People from across the local community, London and the world have voiced their strong opposition to the developer’s plans and to the hotel use and wish for the foundry use to be retained. -
