Abstract: ABSTRACT             A separator for effecting separation of solid materials from liquids has a filter screen arranged so that in operation liquid passes through that screen and solid materials are retained on and travel along that screen in a first direction,   Generator means is provided for subjecting the screen to acoustic pressure waves, the generator means being arranged close to but not touching the screen so that in operation liquid passing through the screen couples acoustic pressure waves from the generator means to the screen.  The generator means is an acoustic pressure wave transducer assembly that stretches at least nearly the whole way across the filter screen in a second direction transverse to said first direction.   Preferably the generator means produces ultrasonic pressure waves and comprises a casing and a plurality of individual ultrasonic transducers within the casing so that a relatively uniform field of ultrasonic waves is produced over the entire width of the screen.  The generator means is adjustable relative to the screen both towards and away from it and in said first direction.

Abstract: ABSTRACT OF THE DISCLOSURE       The sulfides of nickel and cobalt prepared by sulfiding nickel and cobalt-enriched ammoniacal solutions oxidize rapidly (and often pyrophorically) when exposed to normal atmospheric conditions.  The oxidized sulfides then react with water present in the atmosphere in a hydration reaction.  This oxidation and hydration may increase the weight of the sulfides by as much as 150% or more, depending upon such factors as the type of sulfides involved and the duration of the exposure. However, when nickel sulfide, cobalt sulfide, or mixtures thereof are dried, dehydrated, heated at temperatures of about 1000°F. or higher in a substantially inert atmosphere, and then cooled in a substantially inert atmosphere, the sulfides can surprisingly be ex-posed to normal atmospheric conditions for prolonged periods of time without undergoing significant oxidation or hydration.  Consequently, only minimal weight in-creases are observed with the treated sulfides.  The invention is of particular utility where the sulfides must be shipped from one location to another for further processing and will be in transit or storage for long periods of time.

Abstract: Abstract A solar heat system is comprised of a panel or bank of heat collector modules each of which has a fluid-carrying tube of an elongated triangular shape in transverse cross section formed with longitudinally extended inwardly projected heat radiating fins.  A tube is mounted within a concavo-convex reflector of a hyperbolic form such that the side walls of the tube are subject-ed to reflected rays of solar radiation over an effective range of solar exposure of about one hundred and fifty (150°) degrees.          The reflected rays are concentrated in a longitudinally extended focal zone on each side wall of the tube and these zones of con-centrated solar radiation move transversely of a side wall in re-sponse to the angle of the solar rays falling upon the reflector.

Abstract: ABSTRACT OF THE DISCLOSURE             Combustible bricks are manufactured from plant materials by agglomeration under pressure of these materials after pulverization and drying.  Prior to this, the plant materials are subjected to a fermentation and, in the course of fermentation, to a pulverization treatment while controlling this fermentation so as to obtain a destructuration of the cellulosic tissues of the plant materials without producing separation of the lignin.           This process produces small bricks having a good strength and a low moisture content.

Abstract: IMPROVED ELECTROSTATICALLY CHARGED CABLE TRANSDUCER            ABSTRACT OF THE DISCLOSURE         The sensitivity of a buried electrostatically charged cable transducer, such as an electret cable, to mechanical dis-turbances caused by men, vehicles and the like moving on the surface of the ground is greatly improved by disposing the cable loosely in a coextensive rigid hollow member such as a tube.  The inside dimension of the tube is larger than the out-side diameter of the cable, the cable being supported on the inner surface of the tube at longitudinally randomly spaced points.  The cable is thus free to move radially relative to the tube in response to pressure waves or vibrations propagat-ing through the ground and incident on the exterior of the tube so as to bend, twist, compress and/or otherwise stress the cable and generate corresponding electrical signals between the inner and outer conductors of the cable.  The enclosing tube forms no part of the electrical circuit and accordingly may be and pre-ferably is made of low cost nonconductive plastic material: with such a nonconductive tube, the outer jacket or covering of the cable may be omitted so as to further increase energy coupling efficiency between the tube and cable and thus increase the transducer sensitivity.  The plastic tube additionally con-stitutes an effective moisture-proof corrosion-resistant seal for the cable.

Abstract: A B R I D G M E N T           Control of vertical motion of a suspended crane hook assembly to accommodate vertical motion between a station carrying the crane and a station carrying a load is achieved by a transducer on the hook assembly and a control cord depending onto the load station.  Tension above a set value in the cord produced by a crew member on the station causes the hook assembly to descent and below the set value causes it to rise.  Movement of the stations causes a continuous adjustment of tension and the hook assembly follows the motion, extra tension being applied to guide the hook assembly down to the load and vice versa.

Abstract: HINGE PIN                 ABSTRACT OF THE DISCLOSURE           A hinge pin including two, substantially identical sec-tions which when assembled form a cylindrical sleeve.  Each sec-tion has a first end having a cross-section greater than a semi-circle which tapers along its length to a second end having a cross-section less than a semi-circle.  When the two sections are joined together, they form a cylindrical sleeve for use as a readily removable hinge pin.  Ready removal is effectuated by sliding one section away from the other along their tapered lengths, the taper enabling the average diameter of the sleeve to decrease as the two sections are so slid apart.

Abstract: ROTARY ROLLER BIT WITH IMPROVED SEAL MEANS          Abstract of the Disclosure The present invention provides an improved means for sealing-the roller cutter lubrication system in sealed roller bits.  By providing an air barrier in a narrow space between the leg of the bit body and the rotary cutter it is possible to effectively protect any seal, located between the leg and the entry of the cutter, from being damaged.  By providing a narrow space of suitable height it has been found possible to provide such over-pressure inside said space that an effective barrier of air under pressure is provided as an assistance to the seal means provided to seal the roller cutter lubrication system.  This eliminates the risk for dirt and particles to penetrate into the bearing system of the cutter, thus improving the drilling life of the bearings and the drill bit.
