Abstract: A magnetoelastic torque sensor (2) for providing an output signal (24) indicative of the torque applied to a member about an axially extending axis of the member (11), comprising a member which is unitary and of generally homogeneous chemical composition, the member comprising separate magnetically active (ABC) and magnetically substantially passive regions. A first magnetoelastically active region in the member is magnetically polarized in a single circumferential direction and possesses sufficient magnetic anisotropy to return the magnetization in the region, following the application of torque to the member, to the single circumferential direction when the applied torque is reduced to zero, whereby the magnetoelastically active region produces a magnetic field varying with the torque. Magnetic field sensors (6) are mounted proximate to the magnetoelastically active region and oriented with respect thereto to sense the magnitude of the magnetic field at the sensors and provide the output signal in response thereto. The magnetoelastically active region of the member is formed of a polycrystalline material wherein at least 50 % of the distribution of local magnetizations lie within a 90~ quadrant symmetrically disposed around the single circular direction and has a coercivity sufficiently high to prevent irreversible loss of the magnitude of the circumferential polarization.

Inventor: MASON EUGENE E
IPC: A24F13/18
Filed: 1999-09-03
Abstract: A cursory inspection of the device reveals a small "Funnel" but because the funnel (or device) is plugged at the base (or bottom) the name "Funny Funnel" was developed. Unlike a true funnel, the back is flat and highs than the rounded front. The highly visible arcs on the inside of back will be referred to as the "area of promotion," which may be used for advertising, logos, etc. Vehicle use requires a Velcro R "button" for support while home or industrial use requires a supportive base. In both instances the "funnel" can be easily removed for cleaning, etc. A burning cigarette is easily deposited because of the large opening at the top. The cigarette will extinguish itself in seconds and can be relit.      The "funnel" shape of the device, the use of the Velcro R button and the "area of promotion" are new a new concept for cigarette extinguishers.
