The CylinderPreservation and DigitizationProject is a free digital collection maintained by the University of California, Santa Barbara Libraries with streaming and downloadable versions of over 10,000 phonograph cylinder s manufactured between 1893 and the mid 1920s. History The project began in 2002 as a pilot project to test the feasibility of digitizing cylinder recordings on a large scale for preservation and public access and explore issues related to the preservation and digitization of cylinder records. In 2003, the Institute for Museum and Library Services funded the project with a grant for 205,000 and between 2003 and 2005 UCSB library staff cataloged and digitized over 6,000 of the cylinder recordings in the library s collection using an Arch ophone , a modern electrical cylinder player designed in France by Henri Chamoux. The website was released to the public on November 16, 2005. Since outside project funding has ended a further 4,000 cylinders have been added to the archive. Scope of the Collection The archive consists of a broad range of cylinder records manufactured between 1893 and the mid 1920s. The majority were produced by Edison Records in Orange, New Jersey , but the collection also contains cylinders produced by the Columbia Phonograph Co., Indestructible Records and other companies. The majority of the cylinders in the collection are music and include band recordings, popular songs, vaudeville , opera arias, and music for solo instruments such as banjo , violin and accordion , but the archive also contains speeches, comedic monologues and home recordings. The archive currently is just the cylinders in the collection of the UCSB Libraries. Other ...

They maintain a growing library of newspaper clippings, personal photographs, and audio and video recordings, as well as acquisitions from the defunct Pontiac Latin Affairs Office. Plans encompass cataloging the archives of the Azteca Boxing Center, a local boxing training facility. Origins Martha says she was prompted to begin the project after trying to organize her husband s old papers. H. Tom s Padilla Hector Padilla , a native Puerto Rican, had passed on and she felt that the history contained in papers from his tenure as the first Latino city commissioner, as well as lobbying for migrant worker conditions and his efforts in forming the Hispanic Congressional Caucus , were important to the community and needed to be put somewhere. The effort of Martha was expanded as she realized that others in the Latino community deserve recognition. Fear that the records of who has done what would be lost spurred Willie Martinez and others to join Padilla in gathering stories and history of the Pontiac Latino community at large.

Orphan date December 2007 A wheel cylinder is a component in a drum brake system. It is located in each wheel and is usually at the top, above the shoes. Its responsibility is to exert force onto the shoes so they can contact the drum and stop the vehicle with friction . What connects these wheel cylinders to the shoes are usually small rods shaped like a birds beak. It is very similar to a master cylinder and functions in pretty much the same way, consisting of just a simple little plunger on the inside. On older vehicles these will begin to leak and hinder the performance of the brakes, but are normally inexpensive and easy to replace. The wheel cylinder consists of a cylinder that has two pistons, one on each side. Each piston has a rubber seal and a shaft that connects the piston with a brake shoe. When brake pressure is applied, the pistons are forced out pushing the shoes into contact with the drum. Wheel cylinders must be rebuilt or replaced if they show signs of leaking. automotive part stub Category Brakes ... more details
