Abstract: Abstract Linear Beam Tube With Reflected Electron Trap Some electrons reflected from the collector of a klystron form a beam current flowing back toward the input end of the tube.  This beam is modulated and can carry a regenerate signal which distorts the tube's performance when amplifying a television signal.     The reflected electrons are removed by a spiralling transverse magnetic field having a pitch equal to the cyclotron wavelength in the axial magnetic field used to focus the beam.  The rotative sense of the spiral is such that forward-going beam electrons are not affected but returning electrons are accelerated in their cyclotron orbits until they are driven outside the beam and are collected.

Abstract: Abstract of the Invention Blood flow in human limbs is measured non-invasively by a nuclear magnetic resonance blood flowmeter which includes a pair of polarizing magnets whose fields are stabilized by electro-magnets in each pole piece that are energized in accordance with the magnetic flux of the magnets as sensed by a Hall effect sensor.  Blood molecules are either self-tagged by the polarizing field or are separately tagged by a tag coil whose field is orthogonal to the polarizing field.  Once tagged, the variation in the magnetic moment of the molecule due to the tagging is de-tected by the variation in voltage in the receiver coil which is located orthogonally to the transmitter coil so as to reduce cross-coupling therebetween.  Two sets of scanner coils, one located parallel to and the other orthogonal to the polarizing field directions, respectively, are energized to create a pair of intersecting null planes which act to cancel nuclear magnetic resonance response detected by the receiver everywhere but along the line where the two null planes intersect.  By varying the current in the scanner coils, the resulting line of intersection of the null planes can be moved in two dimensions so as to scan the limb thereby allowing blood flow measurement at various locations within the limb.
