Abstract: ABSTRACT          This invention relates to a hydrocarbon-based bonding agent, or binder, for producing carbon bodies, other refractory bodies or adhesives and tamping pastes/ ramming compounds for high temperature use.  The binder consists of two components, A and B, and a catalyst. A is thermo-hardening and/or catalyst-hardening in the temperature range 10 -250°C.  After hardening compon-ent A, the solid matrix is impregnated with component B with a tar which becomes solid at a temperature at least 200°C higher  than the temperature required for harden-ing A.

Abstract: The invention relates to a method of making steel bars and tubes with good mechanical characteristics. The process consists of manufacturing a low alloy steel containing 0.06 to 0.12% carbon as well as additions with well-determined contents of Si, Mn, Nb, Al, B and optionally V. The steel is used in a raw state of hot rolling, optionally followed by tempering. The bars and tubes obtained in this manner are used for applications in which it is necessary to have a high elastic limit associated with high resistance.

Abstract: ANNULAR BLOWOUT PREVENTER            Abstract of the Disclosure An improved annular blowout preventer having a housing, an annular packer mounted in the housing, and a piston mounted in the housing for the application of an axial force to the annular packer;  the annular packer includes a resilient annulus with a circular series of rigid interengaging inserts embedded in its upper face with the inner ends of the inserts being thicker than the outer ends so that the inner ends of the inserts move inward as the resilient annulus is moved and interengaging side projections and recesses with shoulders to ensure substantially uniform inward movement of the inner ends of the inserts to a preselected inner support position for the resilient annulus.          Background Blowout preventers are used to control pressure within oil and gas wells during drilling and completion of the well.          Annular blowout preventers, the type to which the present invention relates, include a single annular resilient packing positioned within a body having means to cause the packing to be moved into sealing engagement with a portion of a pipe string extending through the preventer or against itself to seal a well when no pipe string extends through the preventer.       An annular blowout preventer is shown and described in U.S. Patent No. 3,572,627 to Jones et al.  The packer has a resilient annulus with a circular series of rigid inserts extending through the packer and having irising end flanges on both ends which move to provide end support of the resilient annulus when it is compressed radially inward by pistons.          These pistons are positioned around the resilient annulus to provide a direct inwardly directed radial force on the

Abstract: METAL MELTING FURNACE     ABSTRACT OF THE DISCLOSURE       A refractory lined melting furnace particularly suited for separation of non-ferrous metals with embedded or attached ferrous components, includes a casing or body pivotally mounted and tiltable by means of fluid opera-tors.  The interior is divided by two vertical walls into a combustible waste burning portion for the generation of combustible gases to assist in heating the furnace, and a melt chamber into which a variety of metallic waste can be charged for melting.  A conventional   fire burner is sup-plied to the melt chamber.  The temperature of the melt chamber is raised to the melting point of the metallic waste material having the lowest melting point, e.g. alu-minum, and when the aluminum is melted, the aluminum runs through drainage apertures into a liquid metal holding chamber provided on the floor of the melt chamber.  When the molten metal has drained, the furnace is tilted rear-wardly to discharge the remaining scrap out through rake-out doors at the rear of the melt chamber.  The sequence is repeated with heat being supplied from the combustible gases formed in the combustible waste burning portion, un-til the storage chamber is full whereupon the furnace is tilted and the molten metal discharged from a tapping hole in the front of the storage chamber.

Abstract: ABSTRACT OF THE DISCLOSURE     A web-forming section of a paper machine includes a lower wire loop having a wire run which constitutes a lower wire of the web-forming section and which forms a single-wire initial portion of a dewatering zone of the web-forming section, and an upper wire unit having an upper wire loop which together with a run of the lower wire forms a two-wire dewatering zone constituted by a joint run of the upper and lower wires within which dewatering takes place substantially through the upper wire, wherein a first open faced forming roll is situated within the upper wire loop so that the two-wire dewatering zone begins and curves upwardly in the region of the first forming roll, a forming shoe within the lower wire loop having a curved deck whose center of curvature is ed on the side of the lower wire loop and which guides the joint run of the upper and lower wires, a second forming roll situated within the lower wire loop after the forming shoe and which guides the joint run of the upper and lower wires over a downwardly curved sector thereof.  Initial dewatering occurs in the single-wire initial portion of the dewatering zone to an appropriate extent through the lower wire.  In the two-wire dewatering zone within the range of the first and second forming rolls and the forming shoe situated therebetween, dewatering occurs first within the sector of the first open forming roll in two directions through both the upper and lower wires whereupon within the region of the forming shoe, the dewatering takes place primarily upwardly through the upper wire and thereupon the dewatering pressure is further increased within the range of the second forming roll with dewatering taking place substantially through the upper wire.

Abstract: ABSTRACT OF THE DISCLOSURE      Cutting of a horizontal, cantilevering object of splittable material, such as a de-barked tree trunk or the like, is carried out with the aid of a guided, endless circulating saw chain, an upper cutting part of which is moved from below and upwardly through the object.  The lower edge portions of the cut surfaces at the cut are allowed to bear against each other under the action of the bending moment of the cantilevering object, while the return portion of the saw chain in the cutting area is kept free from the cut surfaces.  The saw chain is guided by a chain guide extending curvilinearly under the object and guiding the return part of the chain.  The chain guide and the guided return part are both outside and below the object during the whole of the cutting operation, while the upper cutting portion of the chain runs straight between the end points of the curved portion of the chain guide.          Towards the end of the cutting operation, the part of the object not yet sawn through is subjected solely to short-duration tensional stress and substantially not to bending stress, whereby splitting the material is avoided.
