Abstract: ABSTRACT OF THE DISCLOSURE         The specification discloses a method for the treatment of sulphurized copper concentrates, which treatment is particularly applicable to copper ores such as bornite, chalcopyrite and chalcocite.  It is well-known that these copper-bearing ores are always accompanied by gangue or other types of ore such as pyrites, quartz and calcite, the major portion of this gangue being eliminated during the preliminary stage in the concentration of the ore.  A concentrate is thus obtained which contains for example approximately 15 to 50% of copper and 5 to 35% of iron. The specification discloses a method which comprises the following stages a) lixiviation of said sulphurized concentrate by an aqueous solution containing cupric chloride formed in situ, at least in part, by oxidation, by means of hydrochloric acid and air, of the cuprous chloride solution resulting from lixiviation; b) partial extraction of the copper contained in the lixiviation solution resulting from the preceding stage, by contacting said lixiviation solution with an organic phase containing a cationic solution, said extraction being accompanied by oxidation by injection of air; c) re-extraction of the copper contained in said organic phase by contacting the latter with an aqueous solution of sulphuric acid and recycling the organic phase to the extraction stage b);  and d) electrolysis of the copper sulphate solution obtained in the preceding stage, with a yield on the one hand of copper and on the other of an aqueous solution of sulphuric acid which is recycled to the re-extraction stage c), part at least of the aqueous phase which results from the partial copper extraction stage b), being recycled to the lixiviation stage a) and constituting a part of said cupric chloride solution.

Abstract: ABSTRACT    An apparatus and method is disclosed for bundling firewood. Relatively large pieces of wood, preferably first split and cut into convenient lengths, are compressed and while compressed have a strap applied therearound after which the applied pressure is released to form a bundle of firewood that is tightly banded.  The apparatus includes a base section having a pair of spaced upwardly opening U-shaped members upon which the pieces of firewood are stacked with the end portions of the firewood supported by the U-shaped members. A pressure platen section is mounted above the base section and includes a second pair of U-shaped members of the base section so that, as the pressure platen is moved downwardly, the pieces of wood therebetween are compressed.  The pressure platen section is moved upwardly and downwardly by hydraulic ram and about eight tons of pressure is preferably exerted to compress and contour the wood into a cylindrical bundle.  While compressed, a strap of band is applied centrally around the compressed wood bundle.  An electro-pneumatic system is utilized to control the sequencing of the app-aratus including automatic actuation of the hydraulic ram and appli-cation of the band to the compressed bundle.

Abstract: Abstract of the Disclosure An internal combustion engine where a combustion chamber communicates via an injection port with an injection chamber whose volume is 0.5 cc ~ 1.5 cc.  During the intake stroke, air-fuel mixture is introduced from an intake port into the combustion chamber, and at the same time, under the influence of high vaccum produced in the combustion chamber, a jet stream of exhaust gas, air or air-fuel mixture is violently injected from the injection port into the combustion chamber via an auxiliary intake passage communicated with the injection chamber through an auxiliary intake valve, so that the jet stream enhances the ignita-bility by scavenging burned gases from around a spark gap and also generates strong swirl and turbulence of air-fuel mixture in the combustion chamber.
