Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a method for recovering a metal or metal alloy in particular a ferro-alloy, by reducing a metal oxide in a reduction zone formed by a coal bed with a reducing gas.  To obtain a metal having a high affinity to oxygen, the coal bed is formed by three static bed layers including a bottom layer of degassed coal covering a liquid sump of reduced metal and slag, a middle layer and a top layer.  Oxygen or an oxygen-containing gas is blown into the middle layer to form a hot reducing gas, and at a distance thereabove, fine-grain oxidic charging material is introduced into the middle layer.  A combustion gas of carbon particles and oxygen or oxygen-containing gas is fed into the top layer.

Abstract: In order to inflate a tyre 2 during its rotation, a flexible tube 3 is arranged on the inner periphery of the rim 1. A pressing roller 5, integrally connected to the wheel-holder and thus stationary in rotation causes a localised restriction of the flexible tube 3. During the rotation of the tyre 2, the air is discharged from an orifice 31 forming an air intake to the internal volume 20 of the tyre 2, via a non-return valve 4. In order to carry out the deflation, a roller presses on a pusher which controls the opening of the valve 4.

Title: Magnetostrictive linear displacement transducer
Inventor: DUMAIS ARTHUR
IPC: G01F23/72
Filed: 1988-07-18
Granted: 1991-09-24
Abstract: Abstract of the Disclosure A liquid level detector of the type in which a magnetostrictive wire extends through the liquid level measurement range and is captured in a tensioned vertical orientation within a stainless steel tube.          Liquid level is measured as a function of the time required for a torsional disturbance imparted the wire near the top to travel along the wire to a magnet which is contained within a liquid level float which slides up and down along the tube.  The torsional disturbances imparted to the wire by means of a piezoelectric crystal to which the wire is easily claimed.  Accuracy is enhanced by measuring liquid level as a function of the elapsed time between an actuation signal and the first zero crossing of the voltage which is induced as the torsional strain passes through the area of influence of the sliding magnet.

Title: Magnetic particle clutch
Inventor: RAYMOND BRUCE C
IPC: F16D37/02
Filed: 1988-11-24
Granted: 1992-09-29
Abstract: ABSTRACT OF THE DISCLOSURE         A magnetic particle clutch is provided for use as a clutch or brake.  The clutch is particularly useful in a hell-copter steering subassembly.  The clutch has an inner rotor and an outer drum with a common axis.  The inner rotor has a shaft on which the outer drum is journaled.  Between the inner rotor and the outer drum is a cylindrical working cavity, which contains magnetic powder.  The outer drum has a peripheral coil and has exterior slip rings for actuating the coil.  Axial flux lines caused by the actuated coil pass through the magnetic powder, causing a chain-like linking of particles of powder, which results in a shear force and torque between outer drum and inner rotor.          In order to prevent shifting of the powder within the cylindrical cavity during tilting of the clutch, a series of conical and radial cavities are disposed at each end of the cylindrical cavity and connecting thereto.  The conical and radial cavities at each end act like powder guides.  Centrifugal force on the powder at clutch start-up distributes evenly the powder peripherally and axially along cylindrical cavity.  Gravity forces on the powder during angular displacements of the clutch in a helicopter during flight do not easily displace the powder out of the cylindrical cavity.  The clutch torque is proportional to coil current and is independent of clutch speed.
