摘要: A magnetic material having a magnetic heating efficiency of at least 4.5×10−8 J.m/A.g in a cyclic magnetic field where the product of the amplitude and frequency of the applied field is less than or equal to 5×108 A/m.s, and the frequency of the applied filed is at least 20 kHz. The ideal magnetic material is characterized by a perfectly rectangular hysteresis loop, i.e. loop squareness of 1, with coercivity of 25 kA/m or less and high saturation magnetization. Preferably the magnetic material has a predominately cubic magnetic crystalline anisotropy. Preferably the magnetic material is a substituted magnetite (Fe3O4) or &ggr;-ferric oxide (&ggr;Fe2O3) crystalline lattice in which some of the iron atoms in that crystalline lattice have been substituted for one or more alternate metals atoms. Desirably, the metal atom is a member of the group: cobalt, zinc, nickel, manganese, magnesium, copper, chromium, gallium, cadmium.

摘要: A clamping device (10) for clampingly interconnecting a first elongate element (17) and a second elongate element (15). The clamping device (10) comprises a shaft (19), and a first clamping member (21) mounted on the shaft. The first clamping member (21) has first and second clamping sections (31, 32) between which the first elongate element (17) can be slidingly received and clampingly engaged. An aperture (73) is provided in the shaft (19) adjacent the second section (32) of the first clamping member (21) to slidingly receive the second elongate member (15). A second clamping member (22) is mounted on the shaft (19) and is displaceable therealong for clamping the second elongate element (15) between the first clamping member (21) and the second clamping member (22). A cam locking mechanism (23) is operably connected to the shaft (19) for selectively moving the clamping device between clamping and non-clamping conditions. In moving the clamping device (10) into the clamping condition, the cam locking mechanism (23) causes displacement of the second clamping member (22) along the shaft (19) such that the second elongate element (15) is clampingly engaged between the first clamping member (21) and the second clamping member (22).
