Abstract: A rolling mill is provided in which the stands can be angularly displaced about the longitudinal axis of the work material so that the drive shaft slopes upwardly or downwardly from the associated output spindle of the drive transmission. This enables rolls of ideal diameter (D.sub.i) larger or smaller by up to 20 mm than the rated ideal diameter for that stand location to be used. A flexible coupling compensates for the angular misalignment of up to 2.degree. between the drive shaft and the output spindle.

Abstract: A reagent and a method for using the reagent for treating a solid material disposed in a liquid medium and having an oxygen-controlled surface condition. The reagent includes a liquid hydrocarbon, a reducing material and an activator material. The liquid hydrocarbon such as mineral oil has a specific gravity different from the specific gravity of the liquid medium. The reducing material such as phosphorous pentasulfide is present in an amount sufficient to establish a reducing environment around the solid material for breaking the oxygen control on the surface of the solid material. The activator material such as zinc thiophosphate is present in an amount sufficient to establish an electrostatic charge on the solid material after the oxygen-controlled surface condition has been broken. A more specific feature of the invention is directed to the method of flotation of extremely fine bituminous coal having an oxygen-controlled surface condition.

The orally administerable product contains an effective concentration of antibacterial compound selected from the group consisting of linolenyl alcohol and linoleyl alcohol to produce an orally administerable product which will resist growth of bacteria selected from the group consisting of Clostridium butyricum, Clostridium perfringens, Streptococcus mutans, Streptococcus mutans BHT and Streptococcus sanguis.

Abstract: An overhead electric conductor with optical fibres loosely housed in the bore of a central core, which bore also contains a greasy water-impermeable medium 4, is manufactured by causing a preformed elongate metal member of U-shaped transverse cross-section and the optical fibres to advance in the direction of their lengths, the rate of advance of the fibres being restrained. As the U-shaped elongate member is transversely folded around the optical fibres greasy water-impermeable medium is injected into the bore of the elongate metal member under a controlled pressure. The consistency of the greasy water-impermeable medium the pressure and rate at which it is injected into the bore and the degree of restraint imparted to the optical fibres 3 is such that, in a predetermined length of the conductor, the length of the optical fibres exceeds the length of the bore by a controlled extent, preferably 1 to 3%.

Abstract: Polymeric residue including toluene diisocyanate is combined with a solvent having a low affinity for polymer solution and a high affinity for toluene diisocyanate to dissolve toluene diisocyanate leaving the polymeric materials in suspension. The polymeric compounds are precipitated and filtered, the filtrate solution distilled and the toluene diisocyanate recovered as a pure product.

Abstract: A method and apparatus for the continuous transfer of particles from a gaseous conveying medium to a liquid conveying medium wherein a liquid is introduced into a cone-shaped inducer so that the liquid flows along the inducer's periphery toward its vertex. A stream of the gaseous conveying medium and entrained particles is directed into the center of the inducer. The particles impinge the liquid and are carried away by it and the gas is exhausted.

Abstract: A tension model device is disclosed which has: Three struts which cross each other at or near the center portion of each strut; and a plurality of corresponding tension strands. The strands are joined from each end of all the struts to each end of the other struts. To facilitate assembly, a removable block is inserted where the struts cross each other. The block has three notches on its surface that engage the struts and space them from each other.

Abstract: A process is provided for encasement and infiltration of cellular tissue to reduce the influx of oxygen and liquid thereto and to retain in situ and retard efflux of liquids and medication therefrom by introducing into said tissue a gel substantially insoluble in said tissue and the body fluids associated therewith.

Abstract: A motor securing device for watercraft such as inflatable boats and rafts and the like including generally downwardly open securing portion which may be defined by a pair of parallel walls and a connecting wall. A motor attachment portion projects generally upwardly from a rear portion of the securing section. A battery-securing shelf extends forwardly from the securing portion. Securing a motor to the upwardly projecting wall and a battery positioned on the supporting shelf provide a counterbalancing action. Retaining structures may be provided to resist undesired displacement of the battery or motor securing clamp.

Abstract: A readily stackable coil package comprises a closed carton 1 which is formed from a folded cardboard blank and which has a pair of oppositely disposed major side walls 2 whose boundary edges 4 lie in parallel planes. Each major side wall 2 has an area 5 of weakness in axial alignment with an area of weakness in the other major side wall. A coil of wire is housed in the closed carton 1 and, also loosely housed in the closed carton, is separately formed means 7 for forming a rigid hollow hub. When it is desired to convert the closed carton 1 into a reel, the areas 5 of weakness are removed to form apertures, the separately formed hub forming means 7 is extracted from the package and is assembled to form a rigid hollow hub extending between and secured to parts of the major side walls bounding the apertures in the major side walls.

Abstract: A method and apparatus are provided for cooling wire rod and wire in which wire rod and wire leaving the last roll block of a finishing mill is delivered to a first portion of a cooling path for the cooling of wire or wire which slopes downwardly from a likewise inclined finishing block at an angle .alpha. of at least 3.degree. so that the wire rod or wire is subject to little or no compressive stress due to the friction between the wire rod or wire and the tube through which the latter passes in order to be subjected to cooling liquid. The wire rod or wire can be placed under tension if the angle of slope .alpha. is sufficiently large and, in an extreme case the first portion of the cooling path can decent vertically. A loop layer receives the wire rod or wire from the first portion and deposits the wire rod or wire in overlapping loops on conveying means where the wire rod or wire is air-cooled.

Abstract: In the location of an earth fault on a sheath of an underground cable, pulses of direct current are applied to the sheath at one location on the cable. A search is made at spaced locations along the cable route for the magnetic field due to a fault current to earth flowing in the sheath which is produced by the applied d.c. pulses using a portable magnetometer, with a visual indicator, and, at each of said spaced locations, the visual indications on the magnetometer are compared with the periods of application of the pulses to the sheath until they correspond. Comparison of the visual indications with the periods of application of the pulses is facilitated by transmitting signals indicative of the periods of current application and using, with the portable magnetometer, a portable receiver arranged to receive the transmitted signals so that the visual indications can be compared with the received signals.
