Abstract: ABSTRACT OF THE DISCLOSURE      Tobacco smoke filters and methods and means for making same wherein the products have both internal and external cavities, with the external cavities being of a limited mature so as to provide a substantially smooth outer surface for attaching conventional plug wrap without the need for attaching conventional plug wrap without the need for an internal glue line.  The external cavities comprise from about 5 to no more than 50 percent of the total outer surface of the inner filter member, preferably between about 20 and 30 percent.  This enables the inner filter member to pro-vide substantially uniform support to the overwrap. The outer cavities may be in the form of elongated, discrete, grooves, a knurled-like pattern or a con-tinuous helical groove.  The resultant filter has high filtration and correspondingly low pressure drop charac-teristics, with the technique of manufacture being such as to permit higher production speeds than with the prior art, resulting in lower manufacturing costs.  The outer grooves are formed by various mechanical ironing or grooving techniques, by crimping or by utilizing jets of steams.

Abstract: ABSTRACT      A method and apparatus for performing a surveying operation to locate, a target subterranean ferromagnetic body having remanent or impressed magnetization.  The surveying operation is conducted from an off-vertical bore-hole adjacent the target magnetic body using magnetic field sensing apparatus, and involves determining the range and direction of the subterranean target with respect to the location of the magnetic field sensing apparatus.  Target direction is determined by measuring three magnetic field components and resolving the measured components into a resultant vector.  Target range is determined by measuring total magnetic field intensity and target body magnetic field intensity gradient in the direction of the off-vertical borehole. Both static and time-varying fields may be detected by the subsurface apparatus.  The methods and apparatus dis-closed may be used in such diverse areas as the location of ore deposits, guidance systems for drilling off-vertical wells to intersect a previously drilled well, and location metallic objects underwater.

Abstract: Abstract of the Disclosure A process for magnetically separating non-magnetic material from a mixture by combining the mixture with a magnetizing solution containing the salt of a magnetic element.  The magnetic atoms attach to available sites on the molecules of the non-magnetic material so as to develop in that material a positive susceptibility.  Thus the material is responsive to the influence of a magnetic field to move the material to a region where it can be analyzed or recovered.  Materials with low positive or negative suscepti-bilities are separated by suspending them in a magnetic salt solution which when subjected to the attraction of a magnetic field develops a differential buoyancy force, pushing the diamagnetic or weak paramagnetic material strongly away from the magnet.  Disclosed are solutions of ferric chloride, manganese chloride, erbium chloride, dysprosium chloride, turbium chloride, and holmium chloride.
