    H.E. Rainier letter to the Equal Suffrage League, September 9, 1914

    No full text
    H.E. Rainier wrote this letter on September 9, 1914, addressed to the Equal Suffrage League, to inform the League of a debate Rainier would be participating in. Rainier requested facts and statistics that would help support women's suffrage in the debate on the issue of equal suffrage. Rainier requested statistics especially on the rates of divorce in states that had already achieved suffrage for women. The Franklin County Woman Suffrage Association was formed in 1912, after the Ohio Constitutional Convention elected to bring to a vote the question of removing the words "white male" from the state constitution with regard to voting rights. Headquartered in the Chamber of Commerce building in Columbus, Ohio, the organization put out regular publications, organized public speeches and meetings, distributed literature and held parades in support of the suffrage movement. Women's suffrage in Ohio was defeated in a special election in 1912 and again in 1914 and 1916 before a resolution narrowly passed in 1917 allowing municipal voting by women in Columbus. In 1920, the 19th Amendment passed, extending the vote to women and prohibiting state and federal government from denying suffrage on the basis of sex

    Mathematical models of gear rattle in Roots blower vacuum pumps

    This paper is concerned with the modelling of gear rattle in Roots blower vacuum pumps. Analysis of experimental data reveals that the source of the noise and vibration problem is the backlash nonlinearity due to gear teeth losing and re-establishing contact. We derive simple non-smooth models for the lightly damped, lightly loaded dynamics of the pump. The models include a time-dependent forcing term which arises from the eccentric mounting of the gears acting at the gross rotation rate. We use a combination of explicit construction, asymptotic methods and numerical techniques to classify complicated dynamic behaviour in realistic parametric regimes. We first present a linear analysis of permanent-contact motions, and derive upper bounds on eccentricity for silent operation. We then develop a nonlinear analysis of ‘backlash oscillations’, where the gears lose and re-establish contact, corresponding to noisy pump operation. We show that noisy solutions can coexist with silent ones, explaining why geared systems can rattle intermittently. Finally, we consider possible design solutions, and show implications for pump design in terms of existence and stability of solutions.<br/
