Methods for preparing magnetic strips are provided in which the strips are manufactured to a thickness of less than about 0.005 inches and are made of a iron-based alloy having a manganese content of from about 8 to about 18 weight percent. The thin strips can be prepared by annealing the alloy, then cold rolling the alloy to reduce its thickness by at least about 40% to produce an initial strip, ...

A method of controlling the build-up of organic and/or inorganic contaminants (e.g., carbonates, nitrates, nitrites, and the like) in an aqueous process stream, comprising directing at least some of the contaminated stream to a heating means wherein at least some of the contaminants are decomposed. Thereafter, the decomposition products are removed and the purified stream is returned to the proces...

To convert an analog current to a digital signal using a high-speed pipelined analog-to-digigal (A/D) converter, the A/D converter may comprise a current sample- and hold (S/H) circuit at the input and several identical pipelined stages, where each stage contains a current S/H circuit, a current interstage low-resolution A/D converter and current references. To improve the speed of pipelined curre...

A damping coupling is provided to reduce the oscillations of the yawing device of a wind power plant. The damping coupling transmits forces from a driving device to a yaw drive, and the damping coupling is arranged and positioned in such a way that the transmitted moment is dependent on the difference in the rotational speeds between the input and the output shafts of the coupling. The damping cou...

A device for detecting alcohol fumes inside a vehicle compartment contains an air nozzle (1) for mounting on the dashboard (2) and linked via a plastic hose (3) to an electronic fuel cell or semiconductor sensor (4) used for measuring the amount of alcohol in the air. Power is supplied to the cell or sensor via the vehicle starting key (14) when it is in the second or third position for turning on...

The output shaft (12) is located in a front ball bearing (17) and a rear ball bearing (18) which is formed with a first cylindrical surface (53) for support of a crown wheel (15). A second cylindrical surface (55) supports the rear bearing. A spline part (54) is placed between the first and second cylindrical surfaces and supports a ring-shaped coupling component (59). The coupling component is pr...

Each conduit (18) is provided with a meter (22) for measuring the amount of tapped-off fluid and a valve (20) which open and closes the feed of fluid. The conduits are connected to a common mouthpiece (34) and a switch (38) operates the drive valve (20). An operating panel (25) is incorporated for selection and indication of available fluid and is placed in the vicinity of the mouthpiece. It is co...
