Abstract: ABSTRACT           A method and apparatus for insertion of rods into wood or wood-like bodies.  A rod preferably made of metal and partially or completely threaded, is introduced into a body that is preferably wooden and previously drilled, applying a rotary motion at one end of the said rod by appropriate means, the rod and the wooden body being thus intimately joined through the effect of self-threading.  When one or several rods go through a number of wooden elements, a very effective union is obtained between the elements.  Through this means the mechanical resistance of a piece can be increased and units can be produced through the accumulation of elements joined by this method.  The units can be articulated.

Abstract: METHOD OF AND APPARATUS FOR DETERMINING WITH PRECISION THE PAYLOAD OF A WATER BORNE VESSEL     Abstract of the Disclosure -The total weight of material loaded into a floating barge is determined with high accuracy automatically.  Human and other error factors are eliminated.  Before and after loading, the angle of list of the barge in the port-starboard plane and the angle of trim in the fore-aft plane, together with the distance from the water surface to a fixed overhead structure and the distance from this structure to a fixed point on the barge deck are measured.  Using the known barge geometry and the above measurements before and after loading, a computer calculates the change in the volume of water displaced due to loading the barge and by using Archimedes' principle and then calculates the payload introduced into the barge.

Abstract: ABSTRACT         A process for the production of ferrochromium by smelting chromite ore and in which ferrochromium fines may form a part of the feed materials, or for the further treatment of ferrochromium fines alone, in each case in the presence of a limited amount of carbonaceous reductant, is provided.  The amount of reductant is generally limited to a maximum of 150% of the stoichiometric amount required for reduction of all the chromium and iron to metal or carbide form and to produce the required level of silicon in the product (normally 2 to 4%).  The process is carried out by feeding the preferably premixed feed materials to a liquid slag phase in the bath of the furnace at a rate chosen to maintain the molten state and temperature of such material. Oxygen is substantially excluded from the reaction zone which is heated by a transferred arc thermal plasma.  The feed materials generally include slagging agents chosen to ensure that the slag liquidus temperature and metal liquidus temperature are roughly the same or that of the slag is less than that of the metal, but in any event such that the slag phase remains liquid throughout the process.

Abstract: ABSTRACT    Three paperboard webs are glued to one another with as little expenditure of energy as possible. After leaving the gluing apparatus, the finished sheets cut to size are ready for shipment. The middle paperboard web is passed through between two steel rolls which apply glue homogeneously to both sides of the web. High linear pressure is produced in the region of the generatrices of the steel rolls respectively touching the web. Such pressure is necessary in order that a highly viscous polymeric synthetic or natural adhesive, preferably with a solids content of more then 50%, can be used. No special drying facilities are needed, and the water-soluble glue allows recycling without problems.
